Understanding the revision of tax status updates on payroll

A labour broker – someone who provides and remunerates workers for a client (for payment)

  • may or not be and in possession of an exemption certificate.
  • The Fourth Schedule allows for an exemption certificate to be issued by SARS to a labour broker (if a set of conditions is met)
  • this absolves the employers from having to withhold PAYE from payments made to the labour brokers.
  • Employers must withhold PAYE from payments made to labour brokers WITHOUT an exemption certificate.
Foreign employment remuneration requirements
  • SARS PAYE Business Requirements Specification (BRS) – any remuneration received due to employment outside of South Africa must be reported on foreign services income codes.
  • irrespective of whether a portion of that amount may qualify for exemption.
  • if a tax resident employee works outside of SA on behalf of an employer, then certain remuneration is exempt from tax (up to a limit of R1.25 million per tax year).
  • IF the following conditions are met:
  1. the employee is working outside SA for a period exceeding 183 full days in total during any 12-month period, and 
  2. for a continuous period exceeding 60 full days during that period of 12 months.
What is standard employment?
  • an employee (including a scholar or student) works for a single employer for at least 22 hours per week.
  • (excludes temporary periods of absence due to exceptional circumstances or a temporary reduction in working hours).
  • is deemed to be in standard employment.
  • should be taxed according to the progressive personal income tax tables.
Tax statuses - how does it work?
  1. The following tax statuses have been renamed to an [Obsolete] tax status in April 2022. (Please refer to release note #29380 for more information).
  • Foreign Employment (No Tax) [Obsolete]
  • Labour Broker (Not Tax) [Obsolete]
  • Standard Employment (YTD) [Obsolete]

2. In future these tax statuses will no longer be available for selection.  Tax statuses available on the payroll that pertain to labour brokers, foreign employment and standard employment include:

  • Labour Broker: Remuneration paid to a labour broker without a valid exemption certificate (IRP30) is subject to employee’s tax. The basic salary will be converted to tax code 3619 if the employee has a valid exemption certificate. If not, the tax code will be 3617 and the employee will be taxed as per the progressive tax tables.
  • Foreign Employment: Apply this tax status for a South African resident employee who earns income in a foreign country. Normal progressive tax tables will be applied but 50 will be added to all tax codes, for example, the ‘Basic Pay’ component’s tax code will display as 3651.
  • Standard Employment (Normal): The normal progressive tax tables will be applied.
  • When adding an employee, the removed tax statuses will no longer be available to select. It will therefore be hidden on screen, when applying APIs and when uploading via bulk actions.
  • Existing employees linked to these removed tax statuses, will display blank in the tax status field.
  • The tax calculation and reports will still apply the tax status in the database.
  • When the user edits the screen, they will need to select a new status from the available list.
  • When accessing the information via APIs and bulk upload, the tax status of the employees linked to the removed tax statuses, will still display. However, when attempting to upload, an error will be returned, since the value does not exist.
  • Validate APIs if necessary.
  • Existing employees linked to an obsolete tax status should be converted to any of the available tax statuses.
  • If an employee’s tax status is changed in the middle of the tax year, a tax recalculation will take place.
  • If the newly selected tax status should be applicable from a specific date, terminate the employee on the Tax Profile screen and reinstate in the next open run selecting the option, Reinstate Starting a New Record.  As a result, the employee will receive separate tax certificates based on the two tax records in the tax year.

EMP501 Reconciliation Prep: Five Must-Do Tasks

Articles main 2024 – 2

Please check that all the information required by the receiver of revenue is correct and complete for all employees. So you will want to draw a report from your payroll system listing the following:

a)      Address of the employee

b)      Banking details of the employee

c)      Identity number or passport number

d)     Tax reference number

Reconcile all tax payments made to the receiver of revenue to the figures declared on the EMP201 form submitted to SARS. These must balance. If they do not balance you need to correct the issue as soon as possible, or make a note of why so that you can explain the differences on your annual submission. The best way to do this is to get the EMPSA from SARS. This shows the actual payments that they have recorded for the year. This can be compared with YTD totals from the payroll system. If they do not tie up then a correction can be made with the February EMP201. This means that the EMP501 reconciliation on Easyfile should not be a problem.

Check to make sure that SARS have received all your EMP201 submissions and that there are no outstanding issues that need to be dealt with. It is always a good idea to keep up to date with SARS documentation.

Articles main 2024 – Keep up to date with SARS

Remind employees with company cars or car allowances to record their mileage from 1 March. Ensure company car details are accurately recorded in the payroll system.

Make sure that all the earnings and deductions are listed under the right Payroll Codes (a list is available on the SARS website). In addition, make sure you have all the information for any retirement annuities you have been processing.

It is a useful exercise to run a ‘test IRP5 upload’ as this can show any oddities like negative 3601 income and negative non-retirement funding income which can be corrected in the February payroll. This also throws up incomplete addresses, business telephone numbers, retrenchment payments without directive numbers etc. These all have to be correct before Easyfile will accept the upload file.

For any assistance or queries, don’t hesitate to contact our Helpdesk at help@paymaster.co.za

Wishing you a smoothe and successful submission period!

New tax year

The New Tax year – starts 1 March

1 March is the day

From 1 March, you will be rolling over into the new tax year. Most payroll systems now “lock down the old tax year” and you can no longer change any of that information. So sort out any issues before the tax year-end. You really don’t want to start having to open the payroll to change earnings or deductions or add information once 7 March has come.

Here are five things that will make your life easier:

1) Check that your employees details are complete

Check that all the information required by the Receiver is correct and complete for all employees. To do this, you need to draw a report from your payroll system listing the following:

  1. Address of the employee.
  2. Banking details of the employee.
  3. Identity, work permit or passport number.
  4. Tax reference number.
2) That all reconciliations are done – payroll deductions to Emp 201 submitted and paid to SARS

Reconcile all Emp. 201 payments made to SARS to the figures declared on the monthly Emp. 201 form submitted to the Receiver. These must balance. (If not, correct the issue as soon as possible – or make a note of why there is a difference, so you can explain it on your annual submission).
The best way to check the balances is the EMPSA from SARS. This shows the actual payments that have been recorded for the year, and can be compared with the year-to-date totals from your payroll system. If this balances then the Emp.501 reconciliation on Easyfile should not be a problem.

3) Confirm all submissions to SARS

Check to make sure that SARS has received all your EMP.201 submissions and that there are no outstanding issues that need to be dealt with. It is ALWAYS a good idea to keep up to date with SARS documentation.

4) Remind company car and travel allowance holders

Remind all your employees who have company cars or car allowance to record their millage first thing on 1 March. Make sure all the details of the vehicle are recorded on the payroll. They will need to upload their log book or make sure that the logbook is complete for the tax year.

5) Resolve any outstanding issues

Make sure that all the earnings and deductions are listed under the right payroll codes. In addition, make sure you have all the information for any retirement annuity and medical aid tax deductions you have made.

It is a useful exercise to run a test IRP 5 upload, since this can show you any faulty issues, such as negative 3601 income or negative retirement funding income which can be corrected in the February payroll. It will also give you any area of incomplete or missing information. These all have to be corrected before Easyfile will accept the upload file.

Foreign tax legislation brings shift in SA payroll management

THE introduction of foreign legislation such as the US Foreign Account Tax Compliance Act (Facta) will bring about a fundamental shift in the way South African employers manage their payrolls.

South Africa has become a signatory to the inter-governmental agreement with the US that requires financial institutions to provide financial information on US citizens in South Africa.

Beatrie Gouws, associate director at KPMG, says Facta was followed by the Common Reporting Standards issued by the Organisation of Economic Co-operation and Development, which has been called Facta ‘on steroids’.

The G20 finance minister endorsed the Common Reporting Standards for the automatic exchange of tax information in February last year with the first exchanges scheduled for 2017.

“It means all the information of foreigners that is in the banking system or financial system will be provided to the South African Revenue Service (SARS) who will share it with other revenue services,” Ms Gouws said at the annual Tax Indaba in Sandton recently.

“The introduction of these two elements is going to explode our world, because things are no longer within the employer and within the payroll where nobody else knows about it. There will be intense scrutiny on what you do and how you do it,” she said.

Another issue that has been causing employers nightmares is the statement of account. Ms Gouws says SARS is permitted to take money from a taxpayers account if the taxpayer is in arrears.

Piet Nel, head of the School of Applied Tax at the SA Institute of Tax Professionals, says a statement of account records all the monthly payments of employee taxes such as pay-as-you earn, skills development levy and unemployment insurance.

The account is supposed to be nil, but differences arise because of the late capturing or recognising of payments by SARS, automatically levying a penalty of 10%.

Mr Nel says if there is a balance outstanding and the employer does not have a suspension of debt request or an instalment agreement, SARS is entitled to take the outstanding amount from the employer’s bank account. This does not happen often but SARS is entitled to do that, he says..

Ms Gouws tells of an instance where an employer was under the impression that his affairs with SARS was in order, and did not request a statement of account regularly.

However, there were some issues with the account of which the employer was unaware. SARS took what it believed was owned from the business account.

The owner could not pay his employees and the factory was subsequently burnt down.

“The ramification of not getting it right is real. You need to check if every single link in the chain is closed,” Ms Gouws warns.

Personal income tax is government’s biggest revenue source and amounts to 35% of the total taxes collected. According to Ms Gouws, 90% of this is collected through the employees’ tax system.

Employers need to realise that they are not simply a conduit for employees’ taxes. There are big tax management risks, she says.

Should I be paying tax?

Should I be paying tax?

It’s something we all wish we did not have to pay and it is one question  that comes up time and time again. There a many questions the average employee or even employer asks and many of them one would assume have obvious answers but tax does not have obvious answers and it is dangerous to hazard a guess when discussing tax and answering questions such as laid out below.

Question:

I earn a basic wage of R1720.00 per week and I have deductions.

My deductions are:

UIF = R17.00

Provident Fund = R111.00

Council Levy = R2.50

Union Fee = R14.05

Sick Fund = R25.80

Funeral Fund = R1.80

Should I be paying tax?

Answer:

R73,650 is the annual tax threshold for the current year and this means anyone who earns less than this will not pay tax.

R73,650 equates to R6137.50 a month or about R1416 per week.

If you earn R1720 per week this is above the weekly threshold and thus you quality to be taxed on the earnings value only. There could well be a few deductions that could bring the amount down and thus below threshold, all the deductions in the example above are tax deductions and the table amount will remain at R1720.

The answer to the question in a nutshell is that PAYE should be deducted from your earnings.

Overview of the basics of employer tax

Overview of the basics of employer tax

By starting a business, you’re helping to create jobs, contributing towards skills development, and even inspiring other entrepreneurs.
But it’s important to get your SARS red tape right from the start if you want to avoid problems and penalties with the tax authorities later down the line. This overview sets out the basics of employer tax – an area where you have no margin for error.
As an employer, you must deduct taxes from employees, file a range of submissions to SARS, and supply your employees with IRP5 certificates that they will also submit to SARS. You must also register all employees for income tax – everyone who is formally employed needs to be registered with SARS.Declarations and forms to be submitted:

  • Monthly Employer Declaration (EMP201) – This form declares the following deductions: PAYE (Pay as You Earn), SDL (Skills Development Levy) and UIF (Unemployment Insurance Fund) contributions.
  • Employer Reconciliation Declaration (EMP501) – Twice a year you must file this reconciliation of all amounts paid to SARS on behalf of your employees. The next deadline is 29 May 2015 – don’t miss it!
  • Employee Tax Certificates (IRP5/IT3(a)) – You must provide these tax certificates to employees after each tax year, and they will submit them to SARS.
  • Cancellation of Tax Certificates (EMP601).
  • Adjustment to Annual Reconciliation (EMP701) – Where you need to make adjustments to past reconciliation and declarations, this is the relevant form.

Employers must submit their Monthly Employer Declaration (EMP201) by the seventh of each month. Then, you will usually submit an interim Employer Reconciliation Declaration (EMP501) in September-October for the six months from 1 March to 31 August. Your final annual EMP501 submission is done during April and May for the tax year 1 March to 28/29 February.

You will normally issue employee tax certificates once a year. Watch out for SARS announcements at the end of each tax year (end of February) to keep ahead of the annual submission dates.

Steps to follow

SARS no longer accepts paper-based declarations for companies with more than five employees. If you have more than 20 employees, you’ll do most of your reconciliations and declarations electronically using the e@syFile software or use the eFiling website if you have under 20 employees.

Remember:

  • Always use the latest version of e@syFile, since SARS will not accept data submitted using an old version of the software.
  • Backup your data before installing an upgrade of e@syFile to protect yourself against the risk of possible data loss during the upgrade process.

Compiling the PAYE data and submitting employers’ tax reconciliation declarations can be easy if you use the right tools – especially a reliable and efficient payroll software system – and keep track of new SARS requirements and legislative changes.

TAX SEASON 2014 FOR INDIVIDUALS

1 July marks the start of the Tax Season 2014 for Individuals.
The annual Tax Season is when you need to complete and submit an Income Tax Return (ITR12) to SARS.
During Tax Season, taxpayers need to submit an ITR12 (which is your Income Tax Return) so we can calculate your tax liability based on your declared income and the tax-deductible expenses incurred for the assessment year (1 March – 28/29 February), which may, in some cases, result in a refund.
The Tax Season runs from July to November every year and for provisional taxpayers who submit via eFiling, until January of the next year.
Here are some handy tax tips to help you easily and honestly submit your ITR12 on time:

Tax Tip #1

Who needs to submit an Income Tax Return (ITR12)?

Not everyone needs to file an ITR12.
Are you:
  • An individual (Provisional or non-provisional taxpayers)?
  • Who earns up to R250 000 for the full tax year?
  • From one employer (that’s your total salary income before tax) and
  • You don’t have a car allowance, the right of use of a company car fringe benefit or any other form of income (e.g. interest or rental income) and
  • Have no deductions that you want to claim for (for example like medical expenses, travel or retirement annuities)?

If you answered yes to all of the statements above, then you don’t need to submit a return.

Top Tip: Trusts are required to submit an annual Income Tax Return (IT12TR), as well.

Tax Tip#2

What do I need to complete my Income Tax Return (ITR12)?

When completing your ITR12, have your relevant material to hand. You may need to refer to these, while completing your return; however, you must not submit them to SARS.
Top Tip: Keep your relevant material (supporting documents) safely in your possession for at least five (5) years in case SARS needs access to them in future.
  • Your Employee Tax Certificates [IRP5/IT3(a)s] which you will get from your employer/pension fund
  • Medical certificates as well as documents for amounts claimed in addition to those covered by your medical aid.
  • Pension and retirement annuity certificates
  • Travel logbook (if you receive a travel allowance or use a company car)
  • Tax certificates that you get from investment income [IT3(b)]
  • Completed Confirmation of Diagnosis of Disability (ITR-DD), where applicable. See more information on our Tax and Disabilitywebpage.
  • Information relating to capital gain transactions, if applicable
  • If you have signed up to our Voluntary Disclosure Programme (VDP) then your VDP agreement between yourself and SARS for years prior to 17 February 2010, where applicable
  • Financial statements, e.g. business income, where applicable. You may for example have a property which you rent out, so you will need to declare this income.
  • Any other documentation relating to income you received or deductions you want to claim.
Remember if you need to change your banking details additional relevant material (supporting documents) may be needed.
Top Tips:

Tax Tip#3

How to submit your ITR12?

  • If you want to file from a mobile device, download our Smartphone App .
  • If you need help while eFiling online, you can access Help-You-eFile, a free service available to all eFilers. Simply click on the Help-You-eFile icon on your eFiling login page or at any point during your eFiling session to be connected, quickly, to a friendly SARS agent who will help you to complete your ITR12.
  • You may ask a SARS branch agent to file it electronically for you. Find your nearest SARS Branch.
  • Post it or put it in the drop box at a SARS branch.

Top Tip: See a list of the SARS branches that will be open on Saturdays from 8:00 – 13:00 during 5 July until 27 September 2014 to help taxpayers submit their ITR12.

Tax Tip#4

Important Due Dates for Tax Season 2014

Depending on how you submit your Income Tax Return (ITR12) to SARS, be sure you know the due date:
  • By post or dropping it off in a SARS drop box – 26 September 2014
  • Electronically at a SARS branch (provisional and non-provisional) – 21 November 2014
  • Non-provisional taxpayers who use eFiling – 21 November 2014
  • Provisional taxpayers who use eFiling – 30 January 2015.

Tax Tip#5

Beware of scams

  • SARS will never ask for your banking or personal details in any communication that you receive via post, email, phone or SMS
  • SARS won’t send you hyperlinks to other websites – even those of banks.
Top Tip: Beware of people who offer to complete your tax return for you and who promise they can get you a refund. See a list of scams and to report any suspicious activity.

Tax Tip#6

Use a registered Tax Practitioner

Please remember that all Tax Practitioners are now required to be registered with a recognised controlling body (RCB) as well as with SARS.
 You can ask your Tax Practitioner for their SARS and Controlling Body registration details to verify that you are working with a registered and reputable practitioner.
Top Tip: You can check if they’re registered with an accredited professional body and you’ve got better protection if they belong to aregistered practitioner association.
 A person who is not registered with a RCB and who prepares tax returns on your behalf will only be able to perform limited functions. They may not charge you and they may not submit the return on your behalf.
In order to submit a return completed by someone who prepares your ITR12:
Top Tip: Even though a Tax Practitioner is completing and submitting your ITR12 on your behalf, the responsibility still rests with you as the taxpayer to make a true declaration and for any outstanding returns, payments and penalties.

CHANGES TO TAX & CUSTOMS REGISTRATION

What is Single Registration?

The way you register for tax & customs and update your existing details has changed from 12 May 2014. SARS will now have a ‘Single Registration’ of a taxpayer across all taxes they pay and legal entities they’re associated with. From a taxpayer’s view, you will only have to register once as a new taxpayer and there-after add only the relevant details when you start paying e.g. VAT. It will also now be easier to update your existing details.

What will be included in Single Registration?

Single Registration will be phased in, starting with:
  • Single registration of taxpayers.
  • A simplified process to apply for:
    • Corporate Income Tax (CIT)
    • Income Tax (including Provisional Tax)
    • Pay-As-You-Earn (PAYE)
    • Value-Added Tax (VAT)
    • Customs and Excise.

What are the benefits of Single Registration?

Taxpayers/registered representatives will now be able to:
  • View all tax types registered for in a central place.
  • Manage all personal information centrally on eFiling or at SARS branch.
  • Register for additional taxes (CIT, PAYE, VAT excluding Customs and Excise) on eFiling provided you are already registered for at least one tax on eFiling.
  • For the first time, taxpayers or legal entities, such as Companies and Trusts, will be linked to their registered representative on the SARS system.  For more information click here.

How does it work?

  • First-time taxpayers:

Top Tip: Make sure you aren’t already registered, by first calling and checking with the SARS Contact Centre on 0800 00 SARS (7277).  Remember your employer may have registered you or if you own a business, go to CIPC, then SARS will automatically register the business.If you are registering as a new taxpayer, you need to:

 

  • Existing taxpayers:
If you’re an existing taxpayer, you can:

Where can I register or change details?

Depending on what you want to do, the following ways will be available:

Top Tip: Registered Representatives must visit a SARS branch first, to record their relationship with their clients on the SARS system. For more information, click here.

I want to SR2.jpg

A few things to note:

  • No registration or updating of details will be accepted by post, SARS drop-box, fax or email any longer.
  • Companies who register with the Companies and Intellectual Property Commission (CIPC) will automatically be registered with SARS for Corporate Income Tax. You will then just need to link any additional taxes to your profile.
  • Should you need to update the company registered name or company registration number, contact the CIPC.

Employers can register employees by using the Income Tax Registration (ITREG) process. Employees may be registered via eFiling, using e@syFile™ Employer or at a SARS branch. For more information see the guide Registration of employees for Income Tax Purposes.

Who can do what?

Depending on your role or mandate, you will be able to do the following transactions:

Single reg - who can do what 2.jpg

 Again, a few things to note:

  • Once-off mandates – how does it work? In exceptional circumstances e.g. incapacitated clients, an individual may be appointed to act on a taxpayer’s behalf once off. The individual appointed must have a signed power of attorney to request a service each time they visit a branch.Top Tip: The individual who will act on the taxpayer’s behalf must be registered with SARS.Once-off mandates will only be allowed under the following exceptional circumstances:
    • Estates
    • Incapacitated/terminally ill client
    • Non-resident
    • Imprisonment
    • SARS Registered Tax practitioners
    • When you are more than 200 km distance from nearest SARS branch. To check your distance to your nearest branch or mobile unit, click here.
  • Registered Tax Practitioners will still be required to produce a signed power of attorney with each branch visit, and their currenteFiling profile will remain unchanged.
  • When Tax Practitioners phone the SARS Contact Centre, a link between the Practitioner and their clients must already exist oneFiling otherwise the Contact Centre will not be able to assist, read more.

Employment Tax incentive Bill (VIDEO)

DOWNLOAD PDF DOCUMENT

The draft Employment Tax Incentive Bill was published on 20 September 2013 and a revised Bill was published on 24 October 2013. The Bill proposes an incentive to employers to employ young employees due to the high unemployment rates amongst the youth. An amount can be deducted from the total PAYE amount in respect of each qualifying employee that is employed. In other words, the employer will reduce the total PAYE liability of the month with the incentive amount. This amount will be available to employers to encourage employment creation. It will, however,
not affect the employee in any way.

Qualifying employees are defined as employees with a South African ID card, who are between the ages of 18 and 29 years and 11 months and who were employed by the employer on or after 1 October 2013.

The employee will only be a qualifying employee if the employee earns more than the minimum wage (according to the sectoral determination or the bargaining council) and earns less than or equal to R6 000 per month. If the employee is not affiliated to a bargaining council or sectoral determination, the employee should earn at least R2 000 per month to be a qualifying employee.

The incentive amounts for each qualifying employee will be as follows:

 

Monthly

Remuneration

Employment tax incentive per month during the first 12 months of employment

of the qualifying employee

Employment tax incentive per month during the next 12 months of employment

of the qualifying employee

R0 – R2 000 50% of monthly remuneration 25% of monthly remuneration
R2 000 – R4 000 1000 500
R4 000 – R6 000 Formula: R1 000 – (0.5x (monthly remuneration -R4 000)) Formula: R500 – (0.25x (monthly remuneration -R4 000))

 

  • Monthly Employer Declaration (EMP201)
  • Employer Reconciliation Declaration (EMP501)

The effective date is January 2014. The new EMP201 for the Month of January 2014 that is payable 07/02/2014 has been changed to the new layout.

 

Employment Tax Incentive (ETi) PAYE Overview:

Impact on Paymaster online – currently in development:

The ETi calculations and qualifying employees will be determined by Paymaster on line.

The new EMP201 will be revised for January 2013

The declaration process/requirements for the yearend 2014 IRP5’s will be revised as per the Business Requirement Specification document released by SARS.

 

The Home office and what you can claim

It is a new way of working, everybody wants to do it and the internet is making working from home a reality. We walk down the stairs and into our office. What a luxury. To do this we have set aside a small space in our house which we call our office. It is here that we do all our work, and earn our money. So what can we claim as a legitimate expense and how should we do this. Can I claim security; can I claim the gardener’s salary?

The receiver of revenue recognises that we have legitimate expenses and will allow reasonable claims. But this privilege has been abused. To avoid exploitation the receiver of revenue has published an interpretation note setting out what can and what cannot be claimed. Read it, it may save you some heartache and some money.

Disclaimer: please read the full interpretation note before making any decisions on a home office

So what is a home office

An area in your home that is specifically marked and equipped in such a manner that this area is used as a home office on a regular basis. Three important things:

1)      Specifically allocated. An area or closed space that looks like you could work there. The dining room table or the lounge couch is not good enough. I think the minimum should be an area that is enclosed and portioned off from the other area in your house.

2)      Equipped as an office. This are should have the tools of the trade available for use. So if you use a computer then there needs to be a computer. If you are a doctor then there needs to be an examination area and equipment.

3)      Regular basis. You need to use the office regularly. Stopping in occasionally to do some work does not qualify.

 

So what can I claim

You can claim all reasonable expenses related to running your home office:

Examples: Interest on your bond, maintenance, water and lights rates and taxes. download interpretation note for full list here

Download Home expenses spreadsheet here.

 

How much can I claim

This is easy. How big is your house (floor area) How big is your office (floor area). You can claim the expenses in the same ratio as the office is to the house. Example if the house is 100 square metres and the office is 10 square metres then you can claim 10 %

If in doubt please speak to a tax advisor for assistance.
