Who must file
In most countries, anyone with income above the tax-free amount who was not fully taxed through payroll withholding must file: the self-employed, landlords, company directors and anyone with more than one income source. Companies file their own return. Check South African Revenue Service (SARS)'s rules for employees, who are sometimes exempt or auto-assessed.
You must file if your income is above the threshold, you had more than one employer or you have other income. Employees with a single employer and income under R500,000 may be auto-assessed.
Tax year and deadline
Every country fixes a tax year and a filing deadline a few months after it ends. South African Revenue Service (SARS) publishes both. Put the deadline in your calendar with a reminder a month before, because late filing is penalised even when no tax is due.
Tax year: 1 March to 28 February.
Tax year 1 March to 28 February. For the 2026 season, auto-assessments ran 1 to 12 July, filing opened 13 July and non-provisional individuals filed by 23 October; provisional taxpayers file by late January.
What you need
Your Tax reference number and login for South African Revenue Service (SARS)'s online service.

Filing step by step
Check for an auto-assessment on eFiling or the MobiApp and accept it if it is correct.
Otherwise open the ITR12 and confirm the pre-populated IRP5 and IT3 data.
Add medical, retirement and travel deductions with supporting documents.
Submit and pay any amount due by the date on the assessment.
Employees and salary tax
Employers in South Africa withhold income tax from salaries under the 2026/27 bands and pay it to South African Revenue Service (SARS). The South Africa salary tax calculator shows the tax and take-home for any gross salary, which is a quick way to check your payslip before you file.
If you are late
Late returns attract a fixed penalty and late payment attracts interest, both set by South African Revenue Service (SARS). File even if you cannot pay in full; penalties for not filing are usually heavier than for paying late, and most authorities allow instalment plans.
Questions people ask
Do I need to file if my employer already deducted tax?
It depends on South Africa's rules. Some countries require every taxpayer to file, some auto-assess employees, others exempt employees with a single employer and no other income. The rule for South Africa is set out above.
What if I had no income?
If you are registered with South African Revenue Service (SARS), you may still have to file a nil return. Failing to do so is treated as a late return in many countries.
Can I file late without a penalty?
Rarely. Some authorities allow an extension if requested before the deadline. Otherwise file as soon as possible; penalties often grow with time.
Should I use an accountant?
If you are employed with no other income, the online service is designed for you. If you run a business or have foreign income or property, an accountant usually saves more than the fee.
