Tax Season Financial Planning: What to Review Every Year

Tax season tends to get treated as an accounting exercise — gather documents, submit a return, move on. But it's also one of the best natural checkpoints in the year to review your broader financial plan, since so much of what matters for tax purposes overlaps directly with your retirement, investment, and estate planning decisions.

Here's what's worth reviewing every year, and why each one matters.

For the 2026 filing season, SARS issues auto-assessment notices from 1 to 12 July, with the broader filing period running from 13 July to 23 October for individual taxpayers. Provisional taxpayers have until 22 January 2027 to file. These dates shift slightly each year, so it's worth confirming the current season's dates directly with SARS or your adviser rather than relying on last year's calendar.

If you receive an auto-assessment and agree with it, no further action is needed — but it's still worth checking it properly rather than accepting it without review, particularly if you have investment income, rental income, or retirement contributions that may not have been fully captured by SARS's third-party data.

Retirement contributions are tax-deductible up to 27.5% of your taxable income or remuneration (whichever is higher), capped at R430,000 per tax year. The increased R430,000 cap applies from 1 March 2026. The 2026 return being filed during this season covers contributions made up to 28 February 2026, when the annual cap was R350,000. If you're a discretionary contributor — topping up an RA with lump sums rather than a fixed monthly amount — tax season is the natural point to check whether you've used your full deduction for the current year, or whether a top-up contribution before the tax year closes could still reduce your next tax bill.

The annual TFSA contribution limit is R46,000, with a lifetime limit of R500,000. The R46,000 annual limit applies from 1 March 2026; for the 2026 tax year currently being filed, the annual limit was R36,000. Contributing more than the annual limit triggers a 40% tax penalty on the excess, so this is worth checking carefully — especially if you hold more than one TFSA across different providers, since the limit applies across all of them combined, not per account.

If you hold discretionary investments, make sure you have the relevant tax certificates (IT3(b) for interest and dividends, IT3(c) for capital gains) from your investment providers before filing. This is also a good moment to check whether your investment structure is still tax-efficient for your current income level, particularly if your income has changed meaningfully since the investments were first set up.

Medical scheme contributions and qualifying out-of-pocket medical expenses both affect your tax position through specific tax credits. Keep records of contributions and any significant medical expenses not covered by your scheme, since these are easy to lose track of during the year and can meaningfully affect your final tax calculation.

If you're already drawing a living annuity income, tax season is a sensible annual point to review your drawdown rate against how your investments actually performed over the past year, rather than leaving it unchanged out of habit. If you're approaching retirement, it's worth using this same annual review point to check whether your broader retirement income structure (living annuity, guaranteed annuity, or a blend) still matches your circumstances.

If you earn income outside of a standard salary — rental income, freelance or consulting work, investment income above certain thresholds — you may be a provisional taxpayer, with separate filing and payment deadlines from salaried employees. It's worth confirming this status annually, since it can change as your income sources change, and missing a provisional tax payment triggers interest and penalties.

Tax season isn't just a compliance deadline — treated properly, it's a useful annual forcing function to check that your contributions, investments, and retirement strategy are still aligned with your actual financial position, rather than running on autopilot from a plan set up years ago. A short annual review, done at the same time you're already gathering documents for SARS, is a far more efficient use of the moment than treating tax season as separate from everything else going on in your financial life.

If it's been a while since you've properly reviewed your contributions, investments, or retirement strategy, tax season is as good a prompt as any to have that conversation.
