UAE corporate tax accounting starts in everyday bookkeeping, not at year end. This checklist shows how to set up your accounting system so the Corporate Tax return is built from clean numbers you can prove.
Key takeaways
If your financial year follows the calendar, your first UAE Corporate Tax period closed on 31 December 2024, and the return and payment are due by 30 September 2025. That sounds like plenty of time until you remember where the return starts: with the accounting profit in your financial statements. Good UAE corporate tax accounting therefore happens in daily bookkeeping, long before anyone opens the return on EmaraTax.
This checklist covers what the law asks of your books and how to set up your accounting system, whether StarBiz, Odoo or another ERP, so that every adjustment traces back to a ledger account.
Not tax advice: this article summarizes rules published by the Ministry of Finance and the Federal Tax Authority as of March 2025. Every business is different, so confirm your treatment with a registered tax agent before you file.
Corporate Tax applies to a business from the start of its first financial year beginning on or after 1 June 2023. Under Federal Decree-Law No. 47 of 2022, taxable income is your accounting income for the tax period, adjusted for items such as exempt income, non-deductible expenditure, transactions with related parties and tax losses.
For most businesses, the rate is 0% on taxable income up to AED 375,000 and 9% on the rest. The return must be filed, and the tax paid, within nine months of the end of the tax period.
Because the starting point is your accounts, the rules also say how those accounts are prepared. Financial statements follow IFRS, although businesses with revenue of AED 50 million or less may use IFRS for SMEs, and those with revenue of AED 3 million or less may use the cash basis. Revenue, in other words, is a figure your ERP must report precisely, because several thresholds depend on it.
| Threshold | Measured on | What it changes |
|---|---|---|
| AED 375,000 | Taxable income | Income up to this amount is taxed at 0%, and the rest at 9% |
| AED 3 million | Revenue | The cash basis is allowed, and resident businesses may elect small business relief |
| AED 50 million | Revenue | IFRS for SMEs is allowed up to this level, and audited financial statements are required above it |
Small business relief is open to resident businesses whose revenue stays at or below AED 3 million in the current and every previous tax period, for tax periods ending on or before 31 December 2026. It is not available to Qualifying Free Zone Persons or members of large multinational groups, and because it is elected in the return, registration, records and filing still apply.
Every Qualifying Free Zone Person also needs audited financial statements, whatever its revenue.
The simplest way to make adjustments reliable is to give each one its own account, or at least its own analytic tag. When a cost that tax treats differently sits inside a general account, someone has to rebuild the add-back by hand at year end, usually from memory.
Review your chart of accounts against the items below, each of which needs its own home in the ledger.
| Account to separate | Corporate Tax treatment | What to set up |
|---|---|---|
| Entertainment of customers, shareholders, suppliers and other business partners | 50% deductible (Article 32) | A dedicated expense account, with staff events kept in a different account |
| Fines and penalties | Not deductible, except compensation for damages or breach of contract (Article 33) | Separate accounts for regulatory fines and contractual compensation |
| Donations, grants and gifts | Deductible only when made to a Qualifying Public Benefit Entity (Article 33) | A separate account, with the recipient recorded on every entry |
| Interest expense and interest income | Net interest above the higher of AED 12 million and 30% of EBITDA, as adjusted for tax, is restricted (Article 30) | Separate accounts, with related-party loans tagged |
| Corporate Tax expense and liability | Corporate Tax itself is not deductible (Article 33) | Dedicated tax expense, provision and payable accounts |
| Input VAT | Recoverable input VAT is not deductible (Article 33) | Recoverable VAT kept on the balance sheet, never in expense accounts |
| Dividends received | Dividends from UAE resident companies are exempt income (Article 22) | Income accounts split by source, resident and foreign |
| Unrealized gains and losses | Relevant if you elect the realization basis (Article 20) | Separate accounts for fair value and foreign exchange revaluations |
| Owner and personal costs | Only expenditure incurred wholly and exclusively for the business is deductible (Article 28) | An owner's current account, so personal costs never reach the profit and loss |
Most of this is configuration, not custom code. Account groups keep the statements tidy, and analytic tags mark individual lines, such as a client dinner on a mixed agency invoice.
An account structure only works if transactions land in the right place, and the cheapest moment to classify a cost is when it is entered.
Transactions between related parties must meet the arm's length standard (Article 34). Related parties include, for example, relatives up to the fourth degree, an individual and the companies they own 50% or more of or control, and companies under common ownership of 50% or more or common control (Article 35).
Connected persons are a separate group: any individual who directly or indirectly owns an interest in the business, its directors and officers, and their related parties. A payment or benefit to a connected person is deductible only to the extent it matches market value and is incurred wholly and exclusively for the business (Article 36), with exceptions for listed companies and businesses under regulatory oversight.
In the ERP, that means three things:
The authority can also require a disclosure of these transactions with the return (Article 55), and its guidance sets when that applies. Larger businesses, with revenue of AED 200 million or more, or part of a group with consolidated revenue of AED 3.15 billion or more, must also keep a master file and a local file. Check the latest guidance from the Federal Tax Authority for the current thresholds.
Article 56 requires a taxable person to keep all records and documents that support the return, and that let the authority readily work out taxable income, for seven years after the end of the tax period they relate to. Exempt persons have the same seven-year duty for the records that prove their status.
In practice, that covers ledgers and journals, sales and purchase invoices, contracts, bank statements, payroll records, fixed asset registers, transfer pricing files and the workpapers behind each Corporate Tax computation. The Tax Procedures Executive Regulation, Cabinet Decision No. 74 of 2023, accepts electronic copies, provided they match the originals and a readable copy can be produced on request.
Backups must therefore be restorable for the full period, and replacing your ERP must not strand old records: if you migrate, keep read-only access to the old database or export complete ledgers and documents first.
With the structure in place, the year-end close becomes a sequence rather than a scramble:
Take a resident trading company with an accounting profit of AED 1,200,000 for the year. Its ledger shows AED 60,000 of client entertainment, AED 8,000 of traffic and government fines, and a AED 12,000 donation to a charity that is not a Qualifying Public Benefit Entity. There is no exempt income, interest restriction, related-party adjustment or loss brought forward.
| Line | AED |
|---|---|
| Accounting profit | 1,200,000 |
| Add back 50% of client entertainment (60,000 x 50%) | 30,000 |
| Add back fines and penalties | 8,000 |
| Add back the donation to a non-qualifying entity | 12,000 |
| Taxable income | 1,250,000 |
| 0% on the first 375,000 | 0 |
| 9% on the remaining 875,000 | 78,750 |
| Corporate Tax payable | 78,750 |
Every adjustment came straight from a dedicated account. Had the entertainment sat in general office costs, the add-back would have been an estimate, and estimates are what a tax audit questions first.
Spreadsheets can do all of this, but an ERP removes the manual steps. Our guide to what an AI-driven ERP does for a growing UAE business covers the wider case. For Corporate Tax, look for the following.
| Requirement | What the system should do |
|---|---|
| Accurate revenue per tax period | Report revenue by period and company from posted entries, with no adjustments made outside the system |
| Traceable adjustments | Dedicated accounts and analytic tags, with drill-down from each report line to the entries behind it |
| Related-party visibility | Flags on partners and employees, and reports that list their transactions |
| Evidence | Attachments on journal entries, bills and expenses |
| Closed periods stay closed | Lock dates, and an audit trail of who changed what and when |
| Statements and workpapers | Balance sheet, profit and loss and general ledger, exported to PDF or XLSX |
StarBiz covers these in its finance core, with fiscal-year locks, period closing controls and a full log of changes. On Odoo, Enterprise Accounting provides lock dates, the full reporting suite and an audit trail that cannot be switched off once enabled, and the UAE localization includes a Corporate Tax report. Test that report against your tax agent's computation before you rely on it.

Under the Ministerial Decision in force in early 2025, audited financial statements are required for taxable persons whose revenue exceeds AED 50 million in the tax period, and for every Qualifying Free Zone Person. Other businesses may still need an audit under company law or their free zone's rules, so check with your auditor and a registered tax agent.
Article 56 of the Corporate Tax Law requires taxable persons to keep the records and documents that support their tax return, and that let the authority readily work out taxable income, for seven years after the end of the tax period they relate to. Exempt persons must keep the records that prove their status for the same period.
Entertainment, amusement and recreation costs for customers, shareholders, suppliers and other business partners are 50% deductible under Article 32, including meals, accommodation, transport and admission fees. Keep them in their own account and record who attended and why, so the add-back can be calculated directly from the ledger.
Yes, if its revenue does not exceed AED 3 million, or in exceptional circumstances on application to the Federal Tax Authority. Businesses above that level prepare accrual-based financial statements under IFRS, or under IFRS for SMEs where revenue does not exceed AED 50 million.
It lets a resident business elect to be treated as having no taxable income for a tax period if its revenue is AED 3 million or less in that period and every earlier one. As of early 2025 it covers tax periods ending on or before 31 December 2026, excludes Qualifying Free Zone Persons and large multinational groups, and is elected in the tax return.
We set up StarBiz or Odoo Enterprise with a chart of accounts mapped to tax adjustments, locked periods and a full audit trail, working alongside your tax agent.
