For many early-stage founders, the terms cash basis and accrual basis sound like accounting jargon best left to auditors. But get the timing wrong in VAT or corporate tax filings, and the result isn’t just messy books—it’s penalties, blocked refunds, or even a valuation haircut during fundraising. Here’s why timing matters and how to stay onside.

Why timing errors hurt startups

• VAT mismatches – Declaring output VAT when invoices are issued (accrual) but reclaiming input VAT only when cash leaves the bank creates gaps. Tax authorities spot the inconsistency and delay refunds.

• Corporate tax exposure – Recognising revenue too early inflates taxable profit; too late and you risk underpayment penalties.

• Investor diligence – If management accounts don’t reconcile to filed returns, investors assume weak controls and increase risk discounts.

Cash basis vs. accrual basis in plain English

Cash basis: You record income when you actually receive cash and expenses when you pay them. Simple, but not always accepted beyond micro‑business thresholds.

Accrual basis: You record income when it’s earned (invoice issued, service delivered), and expenses when incurred even if cash hasn’t moved. Required under IFRS and for most corporate tax regimes in MENA.

Real‑world startup pitfalls

1. Annual SaaS contracts – Invoicing upfront for 12 months but booking it all as current‑period revenue. Tax authority treats it as taxable now, even though service runs across future periods.

2. Deferred expenses – Paying annual software licences upfront but failing to amortise across periods. Results in overstated costs in one month and understated thereafter.

3. Foreign vendor invoices – Expense booked on receipt but cash settled months later. On cash basis this wouldn’t show, but accrual accounting requires recognition immediately—affecting taxable profit.

4. VAT filing errors – Declaring sales VAT on invoice date but forgetting to claim input VAT until payment is made. Creates avoidable working‑capital strain.

Fixes founders can apply this quarter

✔️ Match revenue to service periods – Use deferrals and revenue recognition schedules in your GL.

✔️ Track prepaid expenses – Split annual contracts across months; automate through accounting software.

✔️ Align VAT treatment – Be consistent: accrual for both sales and purchases unless regulator permits cash basis.

✔️ Reconcile monthly – Tie GL revenue/expenses to VAT returns and bank movements. Spot timing gaps early.

✔️ Educate your team – Sales and ops should understand why invoice timing matters for tax, not just finance.

Quick compliance checklist

• Revenue recognition policy documented and applied consistently.

• Deferred income and prepaid expense schedules maintained monthly.

• VAT filings reconciled to GL and bank.

• Annual audit pack includes timing reconciliations.
