Quick answer: VAT and corporate tax reconciliation UAE businesses need starts with one fact: VAT turnover, accounting revenue and taxable income are three different measures. VAT returns report taxable supplies (excluding VAT) by VAT period and tax point. Corporate tax starts from accounting income under the financial statements for the tax period. A difference between them is not necessarily an error, but any unexplained difference should be investigated and documented. Our corporate tax reconciliation services can help.

Finance teams often notice that revenue in the corporate tax return does not agree to turnover in the VAT returns. This does not automatically mean one of them is wrong. This guide explains why the figures differ, which differences are normal, and how to build a reconciliation schedule you can show the FTA, your auditor or your adviser.
Why may VAT turnover and corporate tax revenue differ?
VAT taxable supplies and accounting revenue for corporate tax purposes are different measures:
| Measure | What it is | Where it comes from |
|---|---|---|
| VAT turnover | Value of supplies reported in VAT returns (standard-rated, zero-rated and exempt), excluding VAT | VAT returns, based on VAT tax points and VAT rules |
| Accounting revenue | Revenue recognised under the applicable accounting standards (for example IFRS 15) | General ledger and financial statements |
| Taxable income | Accounting income adjusted under the Corporate Tax law | Corporate tax computation and return |
The two reports follow different rules, cover different periods, and include different items. Do not treat all VAT turnover as accounting revenue, and do not treat all revenue that is not on a VAT return as exempt from corporate tax. Income is exempt from corporate tax only where a specific provision applies.
Differences in tax periods and accounting periods
VAT returns are filed for VAT tax periods, usually monthly or quarterly, which may not line up with your financial year. Corporate tax is calculated for the tax period, which normally follows the financial year used in your financial statements.
Check that the twelve months of VAT returns you are comparing cover exactly the same dates as the corporate tax period. A company with a non-calendar year-end, or with VAT periods that do not align to it, will always show timing differences. Where a company changes its financial year or has a short period, align the VAT periods carefully before comparing.
VAT-inclusive versus VAT-exclusive amounts
VAT returns report the value of supplies excluding VAT, and the VAT amount separately. Revenue in your accounts should also exclude VAT, because VAT collected is a liability to the FTA, not income.
Example: An invoice for AED 52,500 including 5% VAT is revenue of AED 50,000 and VAT of AED 2,500. If your reconciliation starts from invoice totals or bank receipts instead of VAT-exclusive values, the VAT will show up as a false difference. Check that sales ledgers, reports and bank receipts are compared on the same basis.
Credit notes, refunds, advance payments and timing differences
- Advance payments and deposits: VAT can be due when payment is received, but accounting revenue is usually recognised only when the goods or services are delivered. The advance shows in the VAT return but not yet in revenue.
- Invoices after delivery: work delivered in December but invoiced in January may be accrued as revenue in the accounts for the year, but fall into the next VAT period.
- Credit notes and refunds: a credit note reduces VAT turnover in the period it is issued and accounting revenue in the period it is recorded. If these differ, you get a timing difference. Late-posted credit notes can also be a cut-off error.
- Discounts and rebates: volume rebates agreed after the period may be accrued in the accounts but adjusted for VAT only when the credit note is issued.
- Foreign currency: VAT converts foreign currency values to AED under VAT rules, while the accounts use the functional currency and the company’s accounting policy, which can produce small differences.
Exempt, zero-rated, out-of-scope and non-taxable items
| Item | In the VAT return? | In accounting revenue? | Corporate tax |
|---|---|---|---|
| Standard-rated supplies (5%) | Yes, excluding VAT | Yes | Part of accounting income |
| Zero-rated supplies (for example qualifying exports) | Yes, reported separately | Yes | Part of accounting income |
| Exempt supplies | Yes, reported separately | Yes | Part of accounting income, unless a corporate tax exemption applies |
| Out-of-scope supplies (for example services supplied outside the UAE) | Generally not reported | Yes, if it is income | Part of accounting income unless a specific provision applies |
| Interest, dividends, grants, exchange gains | Usually not VAT supplies | Other income, not always “revenue” | Depends on the specific tax rules for that income |
| Deemed supplies, reverse charge, import VAT | Reported for VAT purposes | Generally not revenue | Not income by itself |
Small Business Relief and Qualifying Free Zone Person tests are based on revenue as defined under the Corporate Tax rules, not VAT turnover. Check which measure the relevant test uses before relying on a VAT figure. See our guides to Small Business Relief and free zone corporate tax.
Accounting adjustments and corporate tax adjustments
The Corporate Tax return starts from the accounting income shown in the financial statements, then adjusts it. That means differences can arise at two levels:
- Accounting adjustments: audit adjustments, accruals, provisions, revenue cut-off corrections and prior-period fixes change the accounting figures after the VAT returns were filed.
- Corporate tax adjustments: exempt income, non-deductible expenses, related-party adjustments, reliefs and elections change taxable income but do not change the revenue number reported in the financial statements.
Keep both levels in the reconciliation, so the revenue reconciliation sits in front of the taxable income computation instead of being mixed with it. See our UAE corporate tax guide.
Reconciliation example
The figures below are hypothetical and show the format only. The company has a 31 December year-end, and VAT returns cover the same twelve months.
| Item | Type | AED |
|---|---|---|
| Total supplies per VAT returns (standard-rated, zero-rated and exempt, excluding VAT) | Starting point | 9,800,000 |
| Less: advance payments received in December for services to be delivered next year (VAT on receipt; revenue deferred) | Timing | (300,000) |
| Add: services delivered in December and invoiced in January (accrued revenue; VAT in next period) | Timing | 450,000 |
| Add: credit note dated 28 December shown in the VAT return but posted to the ledger in January | Cut-off, to correct | 80,000 |
| Add: services supplied to a customer outside the UAE (out of scope; not on the VAT return) | VAT scope | 220,000 |
| Add: interest income (not a VAT supply) | Non-VAT income | 40,000 |
| Less: deemed supply of goods taken for own use (VAT only; not income) | VAT-only item | (60,000) |
| Expected income per reconciliation | 10,230,000 | |
| Total income per general ledger and financial statements | 10,225,000 | |
| Unexplained difference to investigate | (5,000) |
Most of the gap here is explained by timing and scope. The credit note cut-off item needs a correction, and the remaining AED 5,000 is unexplained, so it needs investigating before the return is filed. The next step is the corporate tax computation, which starts from the AED 10,225,000 in the financial statements and applies tax adjustments.
How to prepare a reconciliation schedule
- Align the periods. Match VAT periods to the corporate tax period, and note any change of year-end.
- Take VAT turnover from the filed returns, excluding VAT, by line (standard-rated, zero-rated, exempt).
- Take revenue and other income from the general ledger, and agree the total to the trial balance and financial statements.
- List timing items: advance payments, accrued revenue, credit notes, discounts and late postings.
- List scope items: out-of-scope supplies, non-VAT income, deemed supplies, reverse charge and import VAT.
- Check currency and basis: VAT-inclusive versus exclusive amounts and exchange rates.
- Quantify the unexplained difference and trace it to invoices, credit notes, journals or period-end entries.
- Agree to the corporate tax computation: the revenue used for the return should tie to the financial statements.
- Review and sign off, with the preparer, reviewer and date recorded.
Keep the reconciliation between the VAT returns, the general ledger, the financial statements and the corporate tax computation, together with the working papers. The FTA requires corporate tax records to be kept for at least seven years after the end of the relevant tax period. Our accounting services in Dubai can prepare the schedules, and our VAT services can review the returns.
What if the difference is an error?
A difference is not necessarily an error, but unexplained differences need to be investigated. If you find that a VAT return or the corporate tax return was wrong, take advice before changing anything. You may be able to correct a filed return or make a voluntary disclosure, and time limits can apply, so act promptly. Since 1 October 2026, input VAT recovery also requires documented supplier and supply verification. See our guide to the UAE VAT changes from 1 October 2026.
E-invoicing will make transaction data visible to the FTA from 2027, so reconciling now is good preparation. See our UAE e-invoicing readiness checklist.

FAQs
Why does my VAT turnover not match the revenue in my corporate tax return?
They are different measures. VAT returns report taxable supplies by VAT period and tax point, excluding VAT, while the corporate tax return starts from accounting income in the financial statements. Timing, scope and VAT-only items cause normal differences.
Is a difference between VAT and corporate tax revenue always an error?
No. Many differences are explainable, such as advance payments, accrued revenue, credit note timing and out-of-scope income. Unexplained differences should be investigated and documented.
Should VAT-inclusive amounts be used in the corporate tax return?
No. Revenue should exclude VAT, because VAT collected is a liability to the FTA and not income.
Do exempt and zero-rated supplies count as revenue for corporate tax?
Generally yes. They are reported in the VAT return and are usually part of accounting revenue. Income is exempt from corporate tax only where a specific corporate tax provision applies.
Are out-of-scope supplies taxable for corporate tax?
Being out of scope for VAT does not make income exempt from corporate tax. Out-of-scope income that is part of accounting income is generally included unless a specific provision applies.
How long should I keep the reconciliation?
Keep it with the supporting records. The FTA requires corporate tax records to be kept for at least seven years after the end of the relevant tax period.
What should I do if I find a mistake after filing?
Take advice promptly. Depending on the facts, you may be able to correct the return or make a voluntary disclosure, and time limits can apply.
