This guide explains how corporate tax is calculated in Dubai and across the UAE, what counts as taxable income, common traps to avoid, and step-by-step examples you can use to estimate tax liability for a company. It focuses on the rules introduced under the UAE corporate tax regime and is written for business owners, finance teams, and accountants operating in the UAE.
The Basics You Need to Know
- Tax rates: A 0% tax rate applies to taxable profits up to AED 375,000. Profits above that amount are generally taxed at 9%.
- Who it applies to: Resident companies and other taxable persons carrying on business in the UAE, plus non-residents with a UAE permanent establishment or UAE-sourced taxable income.
- Calculation basis: Taxable income starts with accounting profit for the tax period, adjusted by items required by the corporate tax law (add-backs and allowable deductions).
- Special regimes: Free zone entities, qualifying holding companies and large multinationals are treated under specific conditions and may have different effective outcomes.
What Counts as Taxable Income?
Taxable income is generally derived from the net profit reported in the entity’s financial statements, subject to specific adjustments required by the corporate tax rules. Adjustments ensure that certain items are either added back (non-deductible expenses) or excluded (tax-exempt income) before arriving at the taxable base.
Common Adjustments to Accounting Profit
- Add backs: Non-deductible expenses such as certain fines, penalties, and expenses that are not wholly and exclusively for the business.
- Deductions: Commercially incurred expenses that meet the law’s conditions, including employee costs, operating expenses and interest within allowed limits.
- Exempt income: Income types specifically exempt under the tax law (for example, some dividends or qualifying capital gains may be exempt under conditions).
- Depreciation and capital allowances: Accounting depreciation may need adjustment where the tax law prescribes different treatment for capital expenditure.
Step-by-step Calculation
Use these steps as a practical framework to estimate corporate tax liability.
- Start with accounting profit before tax from the profit and loss statement for the company’s accounting period.
- Make statutory adjustments required by the corporate tax law: add non-deductible items and remove tax-exempt income.
- Apply any available tax reliefs such as qualifying deductions, capital allowances or exemptions.
- Calculate taxable income = adjusted profit after all allowed deductions and exemptions.
- Apply the tax rate:
- Taxable income up to AED 375,000 = 0%
- Taxable income above AED 375,000 = 9% on the portion above AED 375,000
- Account for other rules such as group consolidations, loss carryforwards or international minimum tax rules if applicable.
Key Special Cases and Exemptions
Free Zone Businesses
Many free zone entities continue to benefit from tax incentives but must meet specific conditions and compliance requirements to retain preferential treatment under the corporate tax rules. Free zone activities that qualify for a zero rate typically require that the entity conducts substantive operations and meets notification and filing obligations.
Multinationals and Global Minimum Tax
Large multinational enterprises that fall within the OECD Pillar Two scope may be subject to an effective tax rule at a global minimum rate (commonly referred to as 15%). If applicable, those rules can affect the effective tax payable on a group basis.
Exempt Entities and Income
Certain entities (for example, some government entities, public benefit entities) and specific income types may be exempt under the law. Dividends and capital gains can be exempt in particular circumstances, but conditions apply. Always confirm exemption status before assuming zero tax.
Losses, Carryforwards and Group Relief
Loss treatment is available under the corporate tax law subject to continuity and anti-avoidance rules. Losses can often be carried forward and used to offset future taxable profits, but there are conditions and limits. Group relief and group consolidation may be available for qualifying corporate groups, enabling intra-group loss offsetting under specified rules.
Common Mistakes and Pitfalls
- Applying 9% to the entire profit instead of only the portion above AED 375,000.
- Failing to identify tax-exempt income or qualifying deductions correctly.
- Assuming free zone zero rate automatically applies without meeting substance and compliance conditions.
- Mixing up accounting treatments and tax adjustments — not all accounting expenses are tax deductible.
- Missing registration, filing or documentation requirements that trigger penalties.
Practical Checklist Before You Calculate and File
- Prepare final accounting profit before tax for the period.
- List all non-deductible and tax-exempt items and make required adjustments.
- Confirm free zone status and whether conditions for preferential treatment are met.
- Gather supporting documentation for deductions, intercompany transactions and substance.
- Check eligibility for loss carryforward or group relief if applicable.
- Register for corporate tax and file returns by the statutory due date; keep records for the required retention period.
Filing, Registration and Deadlines
Companies and taxable persons must register with the relevant UAE tax authority and file corporate tax returns in line with statutory deadlines. There are also recordkeeping and documentation requirements to support the taxable income calculation. Filing rules and due dates can change, so confirm the current deadlines and payment procedures with the official authority or a qualified tax adviser.
When to Get Professional Help
Consult a tax advisor if any of the following apply:
- Your entity operates across multiple jurisdictions or is part of a multinational group.
- You are a free zone company relying on a preferential tax status.
- You have complex intra-group transactions, transfer pricing concerns or significant non-deductible items.
- You need help with loss utilization, group relief or audit support.
