1. Objectives
By the end of this module you will be able to:
- Determine whether your store is subject to Corporate Tax, and identify its tax period and its deadlines.
- Move from accounting income to taxable income through the common tax adjustments.
- Calculate the tax liability across the two brackets (0% and 9%).
- Assess whether Small Business Relief is worth taking with a calculation rather than an impression, and understand what you give up by choosing it.
- Build an annual tax file that ties your financial statements to your tax return with a trail you can follow backwards.
2. Core concepts
2.1 The basic structure
| The bracket | Taxable income | The rate |
|---|---|---|
| First | Up to AED 375,000 | 0% |
| Second | The excess over AED 375,000 | 9% |
The bracket applies to taxable income, not to revenue. A store with 4 million of revenue and 300,000 of profit pays nothing under this bracket. A store with 900,000 of revenue and 500,000 of profit pays on 125,000 only.
The basis: tax is calculated on financial statements prepared under international standards, after the adjustments the law prescribes. That is why Modules 1–7 were a prerequisite for this one: bad books mean a bad return.
The core deadlines: registration with the Federal Tax Authority per the published schedule for each category · filing the tax return and paying the tax within 9 months of the end of the tax period · keeping records and supporting documents for the prescribed period.
2.2 From accounting income to taxable income
accounting income per the financial statements
+ non-deductible expenditure (added back)
− exempt or non-taxable income (deducted)
± other adjustments (carried-forward losses, related party transactions, interest deduction limits)
─────────────────────────────────────
= taxable income
The common items in an e-commerce store:
| The item | The treatment | Note |
|---|---|---|
| Regulatory fines and penalties | Non-deductible — added back | A late tax filing penalty, for instance |
| Entertainment and hospitality expenditure | Subject to a partial deduction limit | Keep it in its own account to make the adjustment easy |
| The owner's personal expenses | Non-deductible | A consequence of mixing the two accounts |
| Expenses with no supporting document | Non-deductible | No invoice = no deduction |
| Expenses unrelated to the business | Non-deductible | |
| Interest on a loan from a related party | Subject to arm's length rules and deduction limits | An interest-free loan is simpler but does not excuse you from documenting it |
| Discretionary unrealised provisions | May be adjusted | Document the basis of the estimate |
A decisive practical lesson: every non-deductible item must sit in its own account in your chart from the start of the year. A store that mixes fines into "miscellaneous expenses" will spend a week at year end hunting through invoices — or pay tax on deductible expenses because it could not separate them out.
2.3 Small Business Relief
| The item | The detail |
|---|---|
| The threshold | Revenue of AED 3,000,000 or less in the current tax period and in every previous period |
| The effect | The taxable person is treated as having derived no taxable income ⇒ tax of zero |
| Its nature | Elective — you must claim it explicitly when you file the return; it is not granted automatically |
| Availability | Available for tax periods up to 31 December 2029 |
| Who does not qualify | A qualifying free zone person · a member of a multinational group with consolidated revenue above AED 3.15 billion |
What you give up by choosing it:
- You cannot carry forward the losses of that period to set them against the profits of future years.
- You do not benefit from the other exemptions and deductions in that period.
- Revenue is measured gross, not as net profit — a store with 3.2 million of revenue and 80,000 of profit is not eligible, small as its profit is.
The "every previous period" trap: breaching the threshold once in any earlier period ends your eligibility in the periods that follow. A store with 3.4 million of revenue in 2027 is no longer eligible in 2028 even if its revenue drops to 2 million.
2.4 When is the relief the wrong decision?
| The case | The likely decision | The reason |
|---|---|---|
| Profit of 620,000 and revenue of 2.6 million | Take the relief | It saves real tax |
| A loss of 200,000 and revenue of 2.4 million | Do not take it | Record the loss so you can carry it forward against future profits |
| Profit of 300,000 and revenue of 1.8 million | No tax difference | Profit is under 375,000 anyway ⇒ tax is zero either way. Do not give up a carry-forward for nothing |
| Revenue approaching 3 million with strong growth | Plan | You will lose eligibility soon — build your full tax system now |
The rule: the relief is a tool for small profitable years. In a loss year it is harmful, because you are giving up a real asset (a carried-forward loss worth 9% of itself).
3. Worked example — Nuwa, tax year 2026
Step 1 — The annual figures
| The item | Amount (AED) |
|---|---|
| Net revenue | 2,600,000 |
| Accounting income before tax | 620,000 |
Step 2 — The tax adjustments
| The item | Amount | The treatment |
|---|---|---|
| Accounting income | 620,000 | The starting point |
| Add: penalty for late filing of the VAT return | +5,000 | Non-deductible |
| Add: the disallowed portion of entertainment expenditure (20,000 × 50%) | +10,000 | Partial deduction limit |
| Add: the owner's personal expenses posted by mistake to "miscellaneous expenses" | +8,000 | Unrelated to the business |
| Add: expenses with no supporting invoices | +2,000 | No document = no deduction |
| Taxable income | 645,000 |
Step 3 — Scenario (a): without Small Business Relief
| The bracket | Amount | The rate | The tax |
|---|---|---|---|
| The first 375,000 | 375,000 | 0% | 0 |
| The excess | 270,000 | 9% | 24,300 |
| Total | 645,000 | 24,300 |
The tax liability entry at 31 December 2026:
31 December 2026 | JE-0xx | Ref: corporate tax computation 2026
Dr 7010 Corporate Tax Expense 24,300.00
Cr 2500 Corporate Tax Payable 24,300.00
Memo: corporate tax liability for tax year 2026
Step 4 — Scenario (b): with Small Business Relief
Revenue of 2,600,000 ≤ 3,000,000 and this is the first year ⇒ eligible. On electing the relief, Nuwa is treated as having derived no taxable income:
| The item | The value |
|---|---|
| Tax payable | 0 |
| The saving against scenario (a) | 24,300 |
| What you give up | No carried-forward losses (there are no losses at all this year) and no other exemptions |
The decision: taking the relief is right here — a saving of AED 24,300 against giving up benefits that do not apply to a profitable year in the first place.
Step 5 — The forward plan
| The year | Expected revenue | Eligibility | The action |
|---|---|---|---|
| 2026 | 2,600,000 | ✓ eligible | Take the relief |
| 2027 | 4,100,000 | ✗ breached | Full tax system — start preparing in 2026 |
| 2028 | 5,500,000 | ✗ (a previous period breached) | Never eligible for the relief again |
What Nuwa must do in 2026 to be ready for 2027: separate the accounts for the non-deductible items now · document the terms of the founder's related party loan · archive every invoice · fix the tax period and the calendar formally · test the tax calculation on the 2026 figures as a dry run.
4. Exercises
E9.1 — The basic calculation (beginner). Calculate the tax for each of:
(a) taxable income of 290,000 — (b) 375,000 — (c) 512,000 — (d) 1,250,000 — (e) a loss of 60,000.
E9.2 — The adjustments (intermediate). Accounting income of 840,000. The items: traffic fines 3,200 · client entertainment 28,000 (half of it allowed) · a donation to a non-qualifying body 15,000 · accounting depreciation of 40,000 against allowable tax depreciation of 34,000 · the owner's personal expenses 12,500. Calculate the taxable income and the tax payable.
E9.3 — The relief decision (intermediate). For each case: would you take the relief? Justify it with a calculation:
(a) revenue of 2,100,000 and profit of 480,000 — (b) revenue of 2,800,000 and a loss of 150,000 — (c) revenue of 3,150,000 and profit of 260,000 — (d) revenue of 1,400,000 and profit of 310,000 — (e) revenue of 2,900,000 and profit of 900,000, with a loss of 400,000 expected next year.
E9.4 — The effect of a carried-forward loss (intermediate→advanced). A store: 2026 a loss of 220,000 (revenue 2,300,000) · 2027 profit of 700,000 (revenue 3,900,000). Calculate the 2027 tax in two cases: (a) it took the relief in 2026, (b) it did not. How much did the decision cost it?
E9.5 — The tax file (advanced). Design a 12-item checklist for the annual corporate tax file that must be ready before the return is filed: which documents, where each one comes from, and when during the year it is collected (not at the end of it). Tie every item to an account in your chart of accounts.
5. Mini project — "The annual tax return"
Deliverable: a complete annual tax file that can be audited.
What is required:
- The tax bridge sheet: from accounting income to taxable income, line by line, every adjustment justified with a reason and an account reference.
- The tax calculation sheet: the two brackets automatically, with the relief scenario and the no-relief scenario compared side by side.
- The relief decision sheet: eligibility (current and previous), the saving, what is given up, and a one-sentence recommendation.
- The readiness sheet: what has to change in your chart of accounts and in your monthly process so that preparing the next return is automatic and free of surprises.
- A calendar for the year: what is collected monthly, quarterly and annually, with specific dates.
Acceptance criteria:
- [ ] The tax bridge ends at 645,000 for Nuwa's data.
- [ ] The tax without the relief is exactly 24,300.
- [ ] The comparison of the two scenarios covers what is lost, not just the saving.
- [ ] Every adjustment is tied to an account number in your chart of accounts.
- [ ] The readiness sheet proposes at least one specific change to the chart of accounts.
6. The test
9 questions · pass 7/9.
-
What are the two Corporate Tax brackets and their rates? And what are they applied to?The bracket is read off taxable income after the adjustments, not off sales: a store with 4 million of revenue and 300,000 of profit pays nothing, and a store with 900,000 of revenue and 500,000 of profit pays on 125,000 only.
-
A store has 6 million of revenue and 340,000 of profit. What is its tax?All of the 340,000 falls in the first bracket ⇒ tax of zero with no need for any relief — and it is not eligible for the relief in the first place, because its revenue is above 3 million.
-
Which set of items is entirely non-deductible in an e-commerce store?These are the four items Nuwa added back in its tax bridge: 5,000 of late filing penalty + 10,000 for the disallowed portion of entertainment + 8,000 of personal expenses + 2,000 with no invoices = 25,000 of adjustments.
-
What is the Small Business Relief threshold, and what figure is it measured against?The threshold is on gross revenue: a store with 3.2 million of revenue and 80,000 of profit is not eligible, small as its profit is, and the relief is elective — you claim it explicitly when you file the return.
-
Why is electing the relief in a loss year a harmful decision?The tax is zero either way, but electing the relief erases the loss from your record: a preserved loss of 200,000 is worth 18,000 of tax saved in a profitable year to come.
-
A store went over 3 million in 2027. Is it eligible for the relief again in 2028 if its revenue falls?A store with 3.4 million of revenue in 2027 is not eligible again in 2028 even if its revenue drops to 2 million — which is why the full tax system gets built before you reach the threshold, not after.
-
Taxable income is AED 940,000. How much tax is payable?The first bracket is always zero: (940,000 − 375,000) × 9% = 565,000 × 9% = 50,850. Applying 9% to the whole income gives 84,600, and applying it to the first bracket instead of the excess gives 33,750.
-
What is the deadline for filing and paying Corporate Tax after the end of the tax period?The Corporate Tax deadline is 9 months from the end of the tax period; the 28-day deadline belongs to the VAT return in Module 8, and mixing the two is where the late filing penalty comes from.
-
Why must non-deductible items sit in separate accounts from the start of the year?Separating them does not change the tax, it makes calculating it possible: Nuwa's four adjustments came to 25,000 and lifted taxable income from 620,000 to 645,000, and every one of them came out of an account you can read in a minute.
