SARS Tax Deadlines 2025: What Every South African Small Business Needs to Know

A complete guide to SARS tax deadlines for South African small businesses in 2025 — provisional tax, VAT, PAYE, and annual returns. Don't miss a date.

Why SARS deadlines matter more than most business owners realise

Missing a tax deadline with SARS doesn't just mean a fine. It can trigger an automatic administrative penalty, interest on any outstanding amounts, and in serious cases, a formal audit. For a small business already managing tight cash flow, these add-ons can be the difference between a good month and a catastrophic one.

This guide covers the key SARS deadlines South African small businesses need to track in 2025, what each one means, and how to stay on top of them without becoming a tax expert.

Provisional Tax (IRP6)

Provisional tax applies to any person or business that earns income not subject to PAYE deductions — which includes most sole proprietors, companies, and freelancers.

  • First provisional payment: 31 August (for businesses with a February year-end)
  • Second provisional payment: 28 February
  • Third provisional payment (top-up): 30 September

You calculate your estimated taxable income for the year, pay 50% by August and the balance by February. If you underpay by more than the allowed margin, SARS charges penalties on the shortfall.

VAT Returns

If your business is VAT-registered (annual turnover above R1 million, or voluntarily registered), you must submit VAT returns on a two-monthly or monthly basis, depending on your category.

  • Category A businesses: Even months (February, April, June, August, October, December)
  • Category B businesses: Odd months (January, March, May, July, September, November)

The due date is the last business day of the month following the end of the tax period. Late submission attracts an automatic 10% penalty on the net VAT payable.

PAYE and UIF

If you have employees, you are responsible for deducting PAYE (Pay As You Earn) and UIF (Unemployment Insurance Fund) from their salaries every month and paying it over to SARS.

  • Monthly EMP201 return: Due by the 7th of the following month
  • Bi-annual EMP501 reconciliation: Due August and March

The March reconciliation must align with IRP5 certificates you issue to employees. Errors here cause problems for your employees when they file their personal tax returns.

Annual Income Tax Return (ITR14 for companies)

Companies must submit their annual income tax return (ITR14) within 12 months of their financial year-end. For a company with a February year-end, this means filing by February of the following year.

Tax Season for Individuals (ITR12)

If you're a sole proprietor or earn business income in your personal capacity:

  • eFiling (non-provisional taxpayers): Typically October
  • eFiling (provisional taxpayers): Typically January

Dates vary slightly each year — always confirm on the SARS website.

The three biggest mistakes small businesses make with SARS

1. Paying provisional tax only twice

Many business owners don't realise there's a third, optional top-up payment in September. If you've had a good year and underpaid in February, the top-up payment lets you correct this without the underestimation penalty.

2. Not keeping VAT records properly

You can only claim input VAT on purchases if you have a valid tax invoice. Many small businesses lose thousands in VAT claims every year because they can't produce the documentation when needed.

3. Treating the tax deadline as the admin deadline

Your SARS return is only as good as your bookkeeping. If you're trying to reconcile five months of transactions the week before your return is due, you're going to make mistakes. Good bookkeeping is monthly — not tax-time.

A simple system for staying ahead of SARS

Set a recurring calendar reminder for the 25th of each month. Review what returns are due in the next 10 days, confirm everything is in order, and submit early. SARS eFiling works best when you're not rushing. The cost of a few hours of admin per month is nothing compared to the cost of a penalty.
