The Rule, Stated Plainly
The Tax Administration Act requires anyone who has filed a return to keep the records supporting it for five years from the date of submission. For a freelancer, "records" means everything behind the numbers on your ITR12 and IRP6s: invoices, receipts, bank statements, contracts, your logbook, retirement fund certificates, medical scheme certificates, and the working papers behind your estimates.
Two extensions to know: records under any audit or dispute must be kept until the matter closes, however long that takes. And documents establishing the cost of assets — equipment you're writing off, property, crypto purchase records — must survive as long as the asset does, plus five years from the return where its disposal or final write-off appears, because they prove figures on future returns, not past ones.
Why This Is Really About the Burden of Proof
The five-year rule reads like an archiving obligation. What it actually is, is trial preparation. Under the Act, the burden of proving that an amount is deductible sits with you, not with SARS. A verification letter gives you 21 business days to produce the documents behind specified figures. What you can produce, survives. What you can't, gets disallowed — followed by a recalculated assessment and possible understatement penalties.
This is why "I definitely spent it, I just can't find the slip" is a losing position, and why the freelancers who sail through verifications aren't the ones with the most conservative claims — they're the ones with the best filing.
The Documents That Decide Verifications
In rough order of how often they're requested from independent professionals:
- Invoices issued and bank statements — SARS reconciles declared turnover against bank deposits. Undeclared deposits are the fastest route from verification to audit, so keep your own reconciliation noting non-income deposits (transfers between your accounts, loans, gifts).
- Expense receipts and supplier invoices — each showing date, supplier, amount, and description. For anything materially business-related but ambiguous on its face (a laptop, a phone, a flight), a one-line note of the business purpose at time of purchase settles later arguments.
- The vehicle logbook — contemporaneous, per trip, with odometer readings. Reconstructed logbooks are the most commonly rejected document in the entire deduction landscape.
- Home office evidence — floor plan or measurements supporting your apportionment percentage, plus the underlying bills (rent or bond interest, rates, electricity, insurance, cleaning).
- Contracts and engagement letters — these establish that you traded independently, which underpins your entire s11(a) deduction position.
- s11F and medical certificates — the fund and scheme certificates SARS partially pre-populates from; keep your own copies to catch mismatches.
- IRP6 working papers — the dated estimate calculations. If a paragraph 20 penalty question ever arises, the contemporaneous working paper showing a seriously calculated estimate is your defence.
A System That Takes 15 Minutes a Month
The failure mode isn't refusing to keep records — it's keeping them in a shoebox, a WhatsApp camera roll, and three email accounts. The fix is a small amount of structure, applied monthly:
- One folder per tax year, subfoldered by category: income, expenses, vehicle, home office, retirement-medical, SARS correspondence, working papers.
- Photograph or save every receipt the day it happens. Thermal till slips fade to blank in months; the photo is the durable record.
- A monthly 15-minute close: drop the month's documents into the folders, reconcile invoices against bank deposits, update the logbook summary, note anything unusual while you still remember it.
- Redundancy — whatever your primary system, a second copy elsewhere. Five years is a long time in the life of a laptop.
Freelancers who run this loop don't prepare for filing season or verifications; the preparation already exists as a by-product of the monthly close.
What This Buys You Beyond Compliance
The same records that satisfy SARS are the dataset your tax planning runs on. Accurate IRP6 estimates in August and February require exactly this: clean monthly income figures and a running view of deductions. The R430,000 s11F cap, the home office apportionment, the travel claim — every optimisation in the freelancer's toolkit is only usable to the extent the paperwork exists.
Five years sounds like bureaucracy. In practice it's the difference between verifications that cost you an hour and verifications that cost you the deduction.
