UAE VAT Reconciliation Before Filing

Reconcile VAT to the general ledger before filing your UAE VAT return: common differences, a 5% check, source corrections and a reviewed working paper.

A VAT return is only as reliable as the ledger behind it. If the figures in the return cannot be traced to posted invoices, bills, credit notes and journals, a business has little to rely on when the Federal Tax Authority (FTA) asks questions. With many UAE businesses on quarterly tax periods, a short, disciplined reconciliation before each filing is one of the most practical controls a finance team can run.

This guide sets out a step-by-step process for reconciling VAT to the general ledger before you submit your return on EmaraTax.

What the rules say about timing

According to the UAE Government's official VAT return guidance, taxable businesses must file VAT returns with the FTA regularly, usually within 28 days of the end of the tax period. The standard tax period is quarterly for businesses with annual turnover below AED 150 million and monthly for businesses with turnover of AED 150 million or more. Your actual tax periods are the ones assigned to your registration, so always check them on EmaraTax.

Twenty-eight days is not long if differences are only found in the final week. That is why the reconciliation should start as soon as the period's transactions are posted, not on the day of submission.

Why VAT and the ledger drift apart

Differences between the VAT figures in source documents and the balances on the VAT control accounts usually come from a small number of causes:

Manual journals posted directly to input or output VAT accounts without a matching source document.

Wrong tax codes, such as a standard-rated purchase recorded with no VAT, or a non-VAT cost such as payroll given a VAT code.

Date differences, where a document falls in one period but its posting lands in another.

Credit notes and returns that were issued or received but not reflected correctly on both sides.

Rounding at line or document level, which is usually small but should still be explained.

Opening balances and VAT settlements that remain on the control account from earlier periods.

Each of these can be resolved, but only if you can see the difference transaction by transaction rather than as a single unexplained net figure.

A seven-step VAT reconciliation before filing

1. Close the period's transactions first

Make sure all sales invoices, supplier bills, expenses, credit notes and vendor credits for the period are posted. Reconciling a moving target wastes time, so agree a cut-off date with the team.

2. Record a starting position

Before correcting anything, note the original differences. This gives you an audit trail showing what was found and what changed, rather than a reconciliation that simply appears to agree.

3. Compare document VAT with ledger VAT

For output VAT and input VAT separately, compare the VAT recorded on source documents with the balance posted to each VAT control account. Show both sides, not only the net position, because a net difference of zero can hide two opposite errors.

4. Run a reasonableness check at 5%

Take the standard-rated sales base and the standard-rated purchase and expense base, apply the 5% standard rate, and compare the result with the VAT actually recorded. Exclude zero-rated, exempt and out-of-scope items, as well as non-VAT costs such as payroll and depreciation. Any remaining difference should be explained by rounding or should be investigated.

5. Investigate and correct at the source

When a difference is caused by an error, correct the original invoice, bill or journal rather than posting a balancing adjustment to the VAT account. A plug journal makes the reconciliation agree but leaves the underlying document wrong. Where a manual journal is genuinely needed, record the reason and the supporting evidence.

6. Explain what legitimately remains

Some differences are valid, such as timing differences, prior-period settlements or control-account reclassifications. Record each explanation together with a reference to the supporting document so that a reviewer can check it later.

7. Recheck, sign off and keep the working paper

After corrections, rerun the comparison. Once only explained items remain, produce a working paper showing the figures, the explanations and who prepared and reviewed it, and keep it with the return. Remember that recorded input VAT is not automatically recoverable: recoverability, reverse charge and imports still need separate review.

Do not forget the related reconciliations

VAT reconciliation works best alongside the rest of your month-end close. A reconciled bank account confirms that VAT settlements and refunds were actually paid or received, while agreed receivable and payable balances reduce the chance of missing credit notes.

How RQM Books supports the process

RQM Books now includes a dedicated VAT Reconciliation workspace, separate from the VAT report. Finance teams can compare source documents with postings on the VAT control accounts, filter the rows that need attention, open the original document from the row, correct it and recheck the result. A printable working paper records the review, including the 5% check on the standard-rated base, explanations with evidence references and an audit trail. Explanations do not change accounting entries, and the working paper supports the pre-filing review rather than replacing the VAT return.

Tax identity settings and the FTA Audit File are managed in the FTA readiness workspace, and period reports are available through RQM Books reporting.

Make it a routine

Assign an owner for each VAT control account, set a reconciliation deadline well before the 28-day filing window closes, and require sign-off before submission. If you would like to see how this works with your own chart of accounts, contact the RQM Books team for a walkthrough.
