# Source documents explained: what matters most
Source documents are the original evidence of transactions — invoices, receipts, contracts, bank advices — from which the books are built. The FTA's record requirements are, at heart, a source-document requirement: UAE books are only as defensible as their documents.
In practice, this concept shows up in specific bookkeeping actions. The points below translate the definition into what to do: the entries, the reconciliations, the reviews, and the documentation that make the concept real in a working ledger — rather than a textbook paragraph that never touches the books. Revisit the concept whenever the business changes in a way that touches it: treatments that were correct last year can be wrong this year.
Key points
- Capture at source: photo receipts immediately, file invoices on receipt
- File systematically: by period, by type, retrievable
- Electronic copies need legibility and integrity
# Getting source documents explained right
The UAE angle matters because local law sets the frame: record-keeping duties under the Tax Procedures Law, VAT treatment under the VAT legislation, corporate tax implications under FDL 47/2022. Apply the concept inside that frame and the books satisfy both management and compliance at once. Keep the treatment documented with its reasoning: next period's preparer — or next year's auditor — needs to follow it.

Putting it into practice
Apply it this month: identify where the concept touches your books, post or correct the relevant entries, and reconcile the affected accounts. Document the treatment and the reasoning so next period's preparer follows it. If the amounts are material or the treatment debatable, get the position reviewed before filing anything that depends on it — the VAT return, the financial statements, or the corporate tax return. Revisit the concept whenever the business changes in a way that touches it; treatments that were right for last year's business can be wrong for this year's.
# Avoiding mistakes with source documents explained
Where businesses go wrong with this concept, the pattern is consistent: either ignoring it (and discovering the gap at audit) or applying it ritualistically (and missing its purpose). The middle path — understanding the why, then implementing the how proportionately — is what the disciplines above describe. The common thread is the confident misapplication: the concept understood well enough to use, but not well enough to use correctly.

Frequently asked questions
Which source documents matter most?
Sales invoices (revenue proof), purchase invoices (cost and VAT proof), bank statements (cash proof), contracts (terms proof), payroll records (employment-cost proof). Together they cover the P&L and balance sheet; missing any category leaves a hole auditors find. Document the treatment and the reasoning: what is written down is what survives review — by next period's preparer or next year's auditor.
Are scanned documents acceptable?
Yes, where legible, complete, and retained with integrity for the statutory periods — electronic records are expressly accommodated. But 'scanned' means systematically filed and retrievable, not photos lost in a phone gallery. Start this month, not next quarter: the fix belongs in the current close, because every period it waits, it compounds.
What happens if a business cannot produce its records when asked?
Administrative penalties apply for failing to keep or produce the required records — AED 10,000 for a first violation and AED 20,000 for a repeat within 24 months under the penalties legislation. Beyond the fine, missing records mean the FTA can assess tax on estimates, which is almost always worse than the true position.
How long must a UAE business keep its bookkeeping records?
VAT records must be kept for five years after the end of the tax period they relate to, and corporate tax records for seven years from the end of the relevant tax period, under the VAT legislation and Article 56 of the Corporate Tax Law respectively. Records must be kept in a way the FTA can inspect, and produced in Arabic if the authority asks. Keep both clocks in mind: the longer one usually governs.
Can I do my own bookkeeping in the UAE, or does the law require a bookkeeper?
The law does not require you to hire a bookkeeper; it requires you to keep proper records. A founder can keep the books personally if the records are complete, reconcilable, and retained for the statutory periods. Most businesses outgrow DIY bookkeeping when transaction volume rises, VAT registration arrives, or payroll starts — that is when errors and missed reconciliations start costing real money.
