Why your two returns must tell the same story, and how to reconcile them before the FTA asks

Your Corporate Tax return and your VAT returns describe the same business, so the FTA expects them to tell the same story. When they don't, a query usually follows.

The first wave of full-year Corporate Tax returns for calendar-year businesses was due on 30 September 2026. The FTA now holds a complete year of income data from both returns, filed through the same EmaraTax account. That makes cross-checking easy. A gap between the two is not wrong in itself, but an unexplained gap looks like under-declared revenue or over-claimed expenses.

This article covers where the two returns overlap, the mismatches we see most often, and how to reconcile them before the FTA asks.

The FTA does not publish its risk rules. But a few figures appear in both returns and are natural to compare.

The comparison is not one-to-one. Corporate Tax follows accounting rules (IFRS, accrual basis). VAT follows tax point rules. So some difference is normal. What matters is that you can explain it line by line.

1. VAT quarters don't match your financial year

Your financial year may run from January to December, but your VAT quarters may run from February to April, and so on. If you simply add up four VAT returns, you are looking at a different 12 months.

2. Sales recorded at different times

VAT is due as soon as you issue an invoice or receive payment, even if the work isn't done yet. For Corporate Tax, income is counted only when you have earned it. So advance payments, deposits and long projects billed in stages often show up in different years in the two returns.

3. Income that never goes into a VAT return

Some income is not subject to VAT at all, such as dividends, some bank interest, profit on selling shares and income from a branch abroad. It appears in your accounts and Corporate Tax return, but not in your VAT return.

4. Entertainment, cars and staff costs

You cannot reclaim VAT on entertainment, cars available for personal use and some staff benefits. For Corporate Tax, you can deduct only 50% of client entertainment. Businesses often get one or both of these wrong.

5. Buying and selling fixed assets

When you buy an asset, you reclaim all the VAT at once. For Corporate Tax, the cost is spread over several years as depreciation. When you sell an old asset, VAT is charged on the full sale price, but only the profit or loss goes into your accounts.

6. Bad debts and credit notes

You can claim back VAT on a bad debt only after six months and after informing the customer in writing. Your accounts may record a bad debt provision earlier. Credit notes issued after year-end can also create gaps.

7. Different companies in your VAT Group and Tax Group

The rules for joining a VAT Group and a Corporate Tax Group are different, so the two groups often include different companies. Sales between group companies then appear in one return but not the other.

8. Free zone companies

A Qualifying Free Zone Person must split its income into qualifying income (taxed at 0%) and non-qualifying income (taxed at 9%). Its VAT return also shows what kind of sales it makes. If the two don't match, the FTA may question the 0% rate. The FTA has also tightened the rules for free zone companies from 1 January 2026 (FTA Decision No. 6 of 2026).

ABC Trading LLC has a calendar financial year. Its VAT quarters run February to April, May to July, August to October and November to January. Accounting revenue for 2025 is AED 12,200,000. Here is how the VAT figures reconcile to it.

The raw gap between the two returns was AED 20,000, and the individual items were much larger. Each one has a clear cause and supporting documents. That is exactly what an FTA officer wants to see.

1. Read the query closely. Note the tax period, the figures in question and the response deadline.

2. Prepare a reconciliation. Use the format above and explain each reconciling item in one line.

3. Attach the evidence. Include invoices, contracts, the fixed asset register and group structure charts. Under FTA Decision No. 4 of 2026, the FTA can ask to see the accounting system itself, not just exported reports.

4. Correct genuine errors. If the reconciliation uncovers a mistake, file a voluntary disclosure for the return in error rather than waiting for an assessment.

5. Respond on time through EmaraTax. A complete, organised first reply usually closes the matter faster than several partial ones.

▪ Rebuild VAT sales and purchases month by month for the exact financial year.

▪ Keep a year-end schedule of advances, deferred revenue and accrued income.

▪ List all out-of-scope income with amounts.

▪ Tag entertainment, vehicle and staff benefit costs so VAT and Corporate Tax treatments match.

▪ Reconcile fixed asset additions and disposals separately.

▪ Match bad debt write-offs and credit notes across both returns.

▪ Map VAT Group and Tax Group membership and list intra-group transactions.

▪ Free zone entities: check that the qualifying income split fits the VAT supply profile.

▪ Check supplier verification for input VAT: FTA Decision No. 13 of 2026 applies from 1 October 2026.

▪ Keep records for seven years after the end of the tax period, as Article 56 of the Corporate Tax Law requires.

Bottom line: differences between your Corporate Tax and VAT returns are normal. Differences you cannot explain are what trigger queries. A one-page reconciliation prepared at year-end is the cheapest audit protection a business can have.
