UAE corporate tax calculation: the AED 375,000 band
Calculate ordinary UAE corporate tax with worked AED examples, and understand why the AED 375,000 band applies to taxable income rather than revenue.
For a business using the ordinary UAE corporate tax regime, the useful starting question is: what is our taxable income after reviewing the accounts? Sales, money collected and accounting profit can all differ from that figure. Applying a percentage to the wrong starting number produces a neat spreadsheet and an unreliable answer.
The FTA Corporate Tax General Guide describes the ordinary rate bands: 0% on the first AED 375,000 of taxable income and 9% on the excess. This guide works through that calculation for an ordinary taxable person. A relief election, tax credits or a special regime can change the eventual amount payable, so establish those assumptions before using the result to plan a payment.
Build a bridge from the accounts to the tax figure
Start with a completed profit-and-loss statement for the correct entity and tax period. Then prepare a separate tax-reconciliation worksheet. Keep the accounting result intact; record tax adjustments alongside it rather than editing the ledger until it matches an expected tax bill.
A practical worksheet has five columns: account or transaction reference, accounting amount, proposed tax adjustment, reason for the treatment, and supporting document. If the review identifies an amount requiring specialist advice, mark it as unresolved. A guessed adjustment hidden inside a total is much harder to revisit than a clearly labelled question.
For example, a bank payment might settle a supplier invoice, repay a loan, buy an asset or move money between the company’s own accounts. The payment amount alone does not tell you whether an expense belongs in the profit-and-loss statement or how it should be treated for tax. Obtain the contract, invoice and accounting explanation before accepting a category from the bank description.
This work is what makes the eventual rate calculation useful. When the tax figure changes, the worksheet should explain whether the cause was a corrected accounting entry, a reviewed tax adjustment, a relief decision or a credit. Otherwise, a founder comparing this year’s bill with last year’s cannot distinguish business performance from a change in treatment.
Worked example: AED 800,000 of reviewed taxable income
The following is an illustrative calculation, not a customer case. Assume the business is an ordinary taxable company; its final reviewed taxable income is AED 800,000; it makes no Small Business Relief election; and no special regime or tax credit affects the example.
| Calculation step | Amount in AED |
|---|---|
| Reviewed taxable income | 800,000 |
| Portion within the ordinary 0% band | 375,000 |
| Portion above that band: 800,000 minus 375,000 | 425,000 |
| Tax on the excess: 425,000 multiplied by 9% | 38,250 |
The ordinary-rate result is AED 38,250. Multiplying the whole AED 800,000 by 9% would give AED 72,000 and overstate this example by AED 33,750. That difference is the tax incorrectly applied to the first band.
For the stated assumptions, the spreadsheet expression is max(taxable income - 375000, 0) * 0.09. Label the input “reviewed taxable income”, not “revenue” or “bank balance”. A correct formula cannot compensate for an incorrect input.
Now suppose a review changes taxable income from AED 800,000 to AED 760,000. The excess becomes AED 385,000 and the ordinary calculation becomes AED 34,650. The AED 3,600 difference should trace to the documented AED 40,000 change in the tax working paper. This is a sensitivity illustration, not a suggestion that a particular expense or adjustment is deductible.
Use boundary checks before trusting a spreadsheet
Test the formula with numbers that expose common mistakes. At AED 375,000 taxable income, this ordinary-rate calculation gives zero. At AED 400,000, only AED 25,000 is in the 9% band, giving AED 2,250. A negative input should not create a negative tax payment through this simple formula.
Also test the units. If one worksheet uses AED and another uses fils, a number can be wrong by a factor of 100 while still looking plausible in a large report. Put the currency and unit in the column heading and compare the final output with a manual calculation. Keep the treatment of rounding consistent with the reporting process rather than rounding every intermediate amount for convenience.
Finally, separate accounting profit, tax before credits and tax payable into different labelled cells. A dashboard displaying one number called “tax” can conceal whether a later credit or adjustment has already been applied. The reviewer should be able to reproduce each stage without reverse-engineering the spreadsheet.
Check the regime before approving the result
Some businesses need a different analysis. A Qualifying Free Zone Person’s treatment depends on the classification of its income and continuing qualification conditions. Do not automatically subtract AED 375,000 from its non-qualifying taxable income. The free-zone corporate tax guide explains the evidence needed before deciding which calculation applies.
An eligible resident person may instead elect for Small Business Relief. Eligibility is based on its own conditions and revenue history. A small accounting profit does not itself prove eligibility, and a large turnover does not directly tell you the ordinary taxable-income figure. Review relief before treating an ordinary-rate estimate as the final filing position.
If the company has foreign tax, losses, related-party transactions or an unusual restructuring, identify those issues explicitly for review. Do not force them into a basic calculator merely because the calculator accepts a single profit number. A transparent estimate with unresolved items listed is more useful than a precise-looking figure built on unstated assumptions.
Turn the estimate into a reviewable payment plan
Before approval, assemble the final accounts, tax reconciliation, calculation, supporting explanations and any relief or credit assessment. Ask the reviewer to sign off the version used for the return. If a later adjustment changes the result, preserve the earlier version and record why it was replaced.
Use transaction review and categorization to resolve unexplained movements before relying on an estimate. Assign each open item to a person with a due date and identify the document needed to close it. This prevents a year-end list of vague questions from becoming the only record of the review.
Once the amount is approved, check the filing and payment obligations in the official tax account and arrange available funds. An estimate in bookkeeping software is a preparation tool; the submitted return, acknowledgement and correctly allocated payment are the evidence that the compliance task was completed.
