Understanding how to accurately calculate your corporate tax liability is crucial to remaining compliant with UAE tax regulations. The UAE Federal Tax Authority introduced Corporate Income Tax in 2023, whereby businesses must calculate their taxable income by making certain adjustments to their accounting profits.

These changes ensure financial statements prepared under accounting standards are compliant with tax rules set by the FTA. For business owners and finance teams across Dubai and Abu Dhabi, knowing what adjustments to apply can mean the difference between filing correctly and expensive penalties.

Why Tax Adjustments Are Essential in UAE CIT Calculation

Your accounting profit, as shown in your financial statements, rarely equals your taxable income for corporate tax purposes. This gap exists because accounting standards have different principles from tax legislation.

While your financial statements are aimed at showing the true and fair picture of the performance of the business, the UAE Corporate Tax Law is more about defining what income is taxable and which expenses are deductible for tax purposes.

Tax adjustments fill this gap. They adjust your accounting profit to arrive at taxable income that meets the regulations of the FTA. Some expenses that lower your accounting profit may not be permitted as deductions under the tax law, so you will have to add them back.

Likewise, some of the income that goes into the accounting profit may not be subject to corporate tax, and an adjustment should be made for this. Getting these adjustments right is not optional; it forms the foundation of accurate tax compliance.

Common Adjustments That Increase Taxable Income

Several types of expenses usually accounted for in financial statements require adding back for calculating taxable income. Depreciation and amortization are also subject to frequent adjustment due to the fact that accounting depreciation rates may differ from tax depreciation allowances permitted by the FTA. If your accounting depreciation is higher than the tax-allowed amount, you will need to make an addition for the excess amount.

Entertainment costs and some business gifts are restricted under the UAE Corporate Tax Law. While you may be able to record these costs in your profit and loss statement, tax rules restrict or deny their deductibility. Fines and penalties paid to government authorities cannot reduce taxable income and should be added back in full. Similarly, any provisions or reserves that do not meet specific tax deductibility criteria require adjustments.

Related party transactions need to be carefully scrutinised. If you have been dealing with associated companies at non-arm’s length prices, adjustments might be required to reflect market value.

With years of accounting expertise in the UAE, Asad Abbas & Co. assists businesses in identifying these areas of adjustments while preparing taxes so that they stay compliant while optimizing legitimate deductions. Interest expenses exceeding certain amounts under thin capitalization rules and non-deductible portions of employee benefit costs also commonly require upward adjustments.

Common Adjustments That Decrease Taxable Income

Not all adjustments increase your tax burden. Many items can be used to lower the taxable income if identified correctly. Exempt income is the most important income category here. The UAE Corporate Tax Law offers exemptions for qualifying dividends from UAE resident companies, capital gains from qualifying shareholdings and income from qualifying free zone persons, subject to certain conditions. These amounts, while included in accounting profit, must be deducted while calculating taxable income.

Tax depreciation allowances that exceed accounting depreciation are another opportunity for a tax deduction. If tax rules allow for faster write-offs than accounting standards, the difference lowers taxable income. Certain qualifying capital expenditures may also offer accelerated deductions or immediate expensing under certain provisions.

Losses brought forward from previous tax periods can be used to reduce current taxable income, provided that there are conditions and time limits set by the FTA. Businesses operating throughout multiple Emirates are also advised to consider jurisdictional adjustments if they have operations in qualifying free zones as opposed to mainland Dubai or Abu Dhabi locations.

Our team of 40+ qualified professionals, CPAs, CGMAs, and CMAs provide regular advice to clients on maximising legitimate deduction adjustments whilst ensuring full compliance with Federal Tax Authority requirements.

Maintaining Compliance Through Accurate Adjustments

The complexity of tax adjustments makes it valuable to get professional guidance from a reliable Dubai corporate tax consultant for most businesses. The UAE Corporate Tax Law keeps changing with new Cabinet Decisions and Ministerial Decisions clarifying various provisions. What is considered a deductible expense today may have restrictions in the future. Therefore, businesses must have detailed documentation of each adjustment made towards taxable income.

Your corporate tax return must contain a reconciliation schedule as to how you moved from accounting profit to taxable income through specific adjustments. This schedule is of critical importance in the case of FTA audits or inquiries.

Companies operating across different sectors in the UAE, ranging from real estate and construction to healthcare and professional services, face industry-specific adjustment considerations that require specialized knowledge.
