Receiving a letter from SARS notifying you of an audit can send even the most diligent business owner into a panic. But if your books are in order, a SARS audit is simply a process, not a punishment. Preparation is everything, and with modern accounting software and good habits, audit-ready books are entirely achievable.
What is a SARS Audit?
SARS conducts audits to verify that businesses and individuals have declared their income and expenses correctly and that the correct amount of tax has been paid. Audits can be triggered by significant discrepancies between declared income and third-party data, large VAT refund claims, random selection from SARS risk-based programmes, tip-offs, or industry-specific compliance campaigns. An audit does not mean SARS suspects fraud. Many audits are routine verifications. However, being unprepared or uncooperative will escalate the process significantly.
The Five-Year Record-Keeping Rule
The Tax Administration Act requires all taxpayers to retain records for a minimum of five years from the date of submission of the relevant return. This is not optional — failure to keep adequate records is itself a tax offence. Records you must keep include:
- All invoices issued and received including cancelled invoices
- Bank statements for all business accounts
- Cash register receipts and point-of-sale records
- Contracts, agreements, and correspondence relevant to transactions
- Asset registers and depreciation schedules
- Employee payroll records and IRP5s
- All VAT calculations and supporting schedules
Store records in both physical and digital formats. Cloud accounting software like Xage Accounting stores your transaction history securely, making retrieval straightforward. Keep scanned copies of physical documents in a secure, backed-up location.
What SARS Can Ask For
During an audit, SARS may request any or all of the following:
- Bank statements — All business bank accounts for the audit period. SARS will cross-reference deposits against declared income.
- Sales invoices — To verify declared turnover and output VAT
- Purchase invoices and receipts — To verify expenses claimed and input VAT
- VAT schedules — Detailed breakdowns of output VAT and input VAT for each VAT period
- Payroll records — To verify PAYE deductions and employer contributions
- Lease and loan agreements — To verify expense claims and distinguish loan proceeds from income
- Director/shareholder loan accounts — Loans to shareholders can be deemed dividends if not properly structured
SARS will typically give you 21 business days to respond to an initial request for information. Request extensions in writing if you need more time rather than simply missing the deadline.
How Double-Entry Bookkeeping Protects You
Double-entry bookkeeping is not just an accounting convention — it is a built-in audit trail. Every transaction is recorded as both a debit and a credit, creating a complete and self-balancing record of your financial activity. This matters during an audit because:
- Completeness — Every rand that flows through your business is accounted for with no lost transactions.
- Traceability — Every entry links back to a source document. SARS can follow any number from your tax return all the way back to the original transaction.
- Consistency — Your balance sheet, profit and loss statement, and trial balance all agree. Unexplained discrepancies that attract audit attention are immediately visible and can be corrected proactively.
- VAT accuracy — Output VAT on sales and input VAT on purchases are tracked separately and automatically, making VAT reconciliation straightforward.
Xage Accounting uses true double-entry bookkeeping for every transaction. When you issue an invoice, record a payment, or import a bank statement, the system automatically creates the correct journal entries behind the scenes.
Import Your Bank Statements and Match to Invoices
One of the most powerful audit-preparation habits is keeping your bank statements fully imported and reconciled in your accounting software. SARS will almost certainly request your bank statements, and if your declared income does not match the deposits in your bank account, you will need to explain every discrepancy.
When your bank is imported and matched to invoices in Xage Accounting, every customer payment appears as both a bank deposit and a cleared invoice, unexplained deposits stand out immediately and can be investigated and categorised, and your VAT calculations are tied to actual bank activity. Import your bank statements at least monthly. Weekly is better. If SARS ever asks, you can produce a complete matched reconciliation within minutes rather than days.
Reconcile Your VAT Monthly
VAT is the area most frequently challenged in SARS audits because it is where errors are most common and the amounts are often significant. Monthly VAT reconciliation means checking that:
- Your output VAT (15% of taxable sales) matches your invoices for the period
- Your input VAT is supported by valid tax invoices from VAT-registered suppliers
- The net amount you declare on your VAT201 matches your accounting records exactly
A valid tax invoice for input VAT claims must include: the supplier name and VAT number, your name and address, a unique invoice number, the date, a description of goods or services, the VAT amount shown separately, and the total including VAT. Keep a VAT schedule showing every input and output VAT transaction for each period — this is the first thing SARS will ask for in a VAT audit.
Audit Preparation Checklist
- All bank statements imported and matched to transactions in your accounting software
- All invoices issued and received filed and accessible digitally
- VAT201 returns reconciled to accounting records for all open periods
- PAYE and EMP201 submissions reconciled to payroll records
- Asset register up to date with depreciation calculations
- Director loan accounts properly documented and at arm length
- Any large or unusual transactions explained with supporting documentation
- Records retained for at least 5 years
A SARS audit is far less stressful when your books are complete, accurate, and organised. Build these habits into your monthly routine — bank imports, VAT reconciliation, invoice filing — and you will be audit-ready every day of the year, not just when SARS comes knocking.
