Corporate Tax Deductible and Non Deductible Expenses for Dubai Businesses

The Accounting to Taxable Income Bridge

How accounting profit and taxable profit diverge under Federal Decree-Law No. 47 of 2022

Your accounting income follows IFRS rules. It subtracts your costs from your revenue. But taxable income works differently under UAE Corporate Tax Law. Some costs recognised in the accounts are not allowed as deductions for tax purposes. This creates two separate numbers for the same business year: your financial statements show one profit figure, while your Corporate Tax computation shows another.

The add-back mechanism

When an expense is non-deductible, you generally add it back to accounting profit in the tax computation. This add-back raises taxable income compared with the accounting figure. Think of it as correcting profit for tax purposes only. Disallowed expenditure goes through this adjustment step, and incorrect treatment can cause problems during tax return preparation.

Why overstating deductions triggers FTA audit exposure and penalties

The Federal Tax Authority can review filings and supporting records. If you claim expenses that should not be deducted, the FTA may examine the figures and assess additional tax or administrative penalties where applicable. Careful classification from the start helps avoid this problem.

The Core Deductibility Test: Article 28’s “Wholly and Exclusively” Standard

What “wholly and exclusively for business” excludes by default

Article 28 sets a central rule for expense claims: expenditure must be incurred wholly and exclusively for the purposes of the taxable person's business, subject to the law's specific provisions. Costs with a personal element may need to be excluded or apportioned. Expenses with no clear business purpose generally fail this test, as do losses not connected with the business.

Capital expenditure vs. revenue expenditure distinction

Not all business spending counts as an immediate deductible expense. Capital expenditure buys or improves something that provides benefits over multiple years, such as equipment or property. Revenue expenditure covers day-to-day running costs. Capital expenditure is generally dealt with through the applicable accounting treatment, including depreciation or amortisation where relevant, rather than deducted immediately in full.

Expenses tied to exempt income

Some business income may be exempt from Corporate Tax. Dividends under the participation exemption and qualifying foreign permanent establishment income are common examples. Expenditure incurred to derive exempt income may be non-deductible under the relevant rules. The exemption and expense connection should be assessed under the applicable statutory provisions.

Fully Deductible Expense Categories

Salaries, wages, and employee-related costs

Salaries and wages for staff are generally deductible when they relate to genuine employment and business activity. This can cover payroll costs under employment contracts, staff remuneration, and standard employee benefits. These costs represent ongoing business operations, provided the amounts and arrangements are properly supported.

Rent and utilities for business premises

Rent paid for an office, shop, or warehouse is generally deductible when the premises serve a genuine business purpose. Utilities connected with those premises are treated similarly. This includes electricity, water, and other operating costs. Any personal-use element should be identified and treated appropriately.

Depreciation and cost of goods sold

Depreciation allocates the cost of fixed assets over their useful life under the applicable accounting treatment. Cost of goods sold includes raw materials and direct production costs. Purchases needed to run core operations are reflected in the accounts, with tax adjustments made where required by law.

Professional and advisory fees

Auditor fees, consultant fees, and legal service fees are generally deductible when incurred for business purposes. These services support compliance and business decisions. Fees for professional bookkeeping and advisory support can also qualify. Keep invoices and engagement documents as evidence of the expense and its business purpose.

Genuine bad debts

Bad debts may be deductible when the relevant conditions are met. The debt should be genuine, appropriately recognised, and supported by evidence of the write-off and collection efforts where relevant. Proper procedures help show that the loss is real rather than an unsupported claim made for a tax benefit.

Employee-wide entertainment: 100% deductible

Spending on staff welfare across the team may be fully deductible where it is incurred for business purposes and does not fall within a restricted category. Staff training events and internal meetings are common examples. The important distinction is who benefits from the spending and whether the expense is genuinely business-related.

Entertainment and Hospitality: The Three-Tier Deduction Rule

Client, supplier, and shareholder entertainment

Entertaining customers, suppliers, or business partners is treated differently from ordinary staff costs. Entertainment expenditure may cover meals, accommodation, transport, and similar hospitality for external parties. Under the applicable Corporate Tax rules, qualifying entertainment expenditure is generally only 50% deductible. The remaining portion is added back during the tax computation.

Employee-wide events and welfare

Reward meals, overtime meals, and general staff welfare costs may be treated differently from external-party entertainment. Where the expense is a genuine business cost for employees and no specific restriction applies, it may remain fully deductible. Keep records that clearly identify the event, attendees, and business purpose.

Personal-benefit employee perks fully disallowed

Some spending looks like a staff benefit but actually serves personal interests. Family-member travel or purely leisure accommodation may be personal expenditure even if an employee requested it. Personal costs should not be claimed as business deductions without a valid basis under the law.

Worked example: splitting a mixed invoice across the three tiers

Imagine one invoice covering a client meal, a staff bonus, and a family hotel stay. Each line needs separate treatment. The client meal may be subject to the 50% entertainment restriction. The staff bonus may remain deductible if it is a genuine business expense. The family hotel stay is generally personal expenditure and should be excluded from the deduction. This apportionment process creates a clearer record for a future FTA review.

Interest Expense Deductibility Limits

The general rule: net interest expense deductible up to 30% of EBITDA

Article 30 limits the deduction of net interest expenditure for businesses within its scope. The general cap is based on 30% of the relevant EBITDA calculation. Net interest expenditure takes account of interest expenditure and interest income under the applicable rules. The statutory calculation and exclusions should be checked for the relevant tax period.

The AED 12 million de minimis threshold

The general interest limitation may not apply where net interest expenditure does not exceed the AED 12 million de minimis threshold, subject to the legislation. Businesses with substantial borrowing should monitor their net interest expenditure closely.

Carry forward of disallowed interest for up to 10 years

Where interest expenditure is disallowed under the limitation, the eligible excess may be carried forward for use in later tax periods, subject to the statutory conditions and time limits. Proper records of the disallowed amount and each subsequent utilisation make future calculations easier to support.

Related-party interest exclusions and anti-avoidance intent

Interest paid on certain loans involving related parties can face additional restrictions, including rules designed to prevent arrangements whose main purpose is obtaining a Corporate Tax advantage. The FTA may scrutinise the commercial purpose and terms of loans between connected businesses. Genuine financing should be documented and assessed against the relevant provisions.

Exemptions for banks, insurers, and regulated financing/leasing entities

Some categories of businesses may be excluded from the general interest limitation, depending on their status and the specific statutory conditions. Banks, insurance businesses, and certain regulated financing or leasing entities should confirm whether an exclusion applies to them.

Non-Deductible Expense Categories

Dividends and profit distributions to owners/shareholders

Dividends paid to shareholders are not deductible business expenses. A profit distribution shares existing profit rather than creating an operating cost. Recording dividends as an expense in the books is a common mistake and should be corrected in the tax computation. Shareholders receive a distribution of profit, not a business cost deduction.

Personal expenses of owners or directors booked through the business

An owner's personal holiday paid for with company funds is generally not deductible. Personal expenditure remains disallowed regardless of how it is recorded. A director's personal costs booked as business expenses need to be identified and corrected. Clear separation between business and personal spending helps prevent these errors.

Fines and penalties paid to government authorities

Traffic fines, VAT late-filing penalties, visa fines, and penalties for regulatory breaches are generally non-deductible. However, compensation or contractual amounts paid to a customer under a commercial contract may require a different analysis. The nature of the payment and the specific legal provision should be checked before classifying it.

Bribes and illegal payments under UAE law

Bribes and illegal payments are not legitimate deductible business expenditure. This includes unlawful payments to public officials and payments that lack a genuine lawful service or business purpose. These amounts should be excluded from tax deductions in accordance with applicable law.

Donations to non-qualifying entities

Charitable giving is deductible only where the relevant legal conditions are met. The deduction generally depends on whether the recipient is a qualifying public benefit entity under the applicable rules. Donations to organisations that do not qualify are generally non-deductible. Verify an organisation's status and retain evidence before claiming a deduction.

Corporate Tax itself and other tax penalties

Corporate Tax payable is not deductible when calculating taxable income. Administrative penalties and late-filing or late-payment penalties are also generally non-deductible. Treating these amounts as ordinary business costs can understate taxable income. Keep them separate from genuine operating expenses in your accounting and tax working papers.

Recoverable VAT treated incorrectly as a business expense

Recoverable input VAT should generally not be treated as a Corporate Tax expense because it can be recovered under VAT rules. If VAT is not recoverable, its treatment depends on the circumstances and relevant tax rules. Keep VAT and Corporate Tax records aligned so that the same amount is not incorrectly treated in the calculation.

Related-Party Transactions and Director Remuneration

Why paying yourself a salary is deductible but must reflect market-rate compensation

A director's salary may be deductible when it is a genuine business expense and the amount is consistent with the applicable tax rules. Payments involving related parties are subject to the arm's length principle. Remuneration should reflect the role, responsibilities, and services actually provided. An unusually high amount without supporting evidence can create tax risk.

How the FTA may recharacterise excess salary as a non-deductible profit distribution

If remuneration appears excessive compared with the work performed and market conditions, the arrangement may attract scrutiny. The tax treatment of the excess depends on the facts and applicable law. Keep a clear record of responsibilities, approvals, services performed, and the basis used to determine the compensation.

Practical benchmark: what would an independent party be paid for the same role?

A practical test is to consider what an independent party might receive for the same role under comparable conditions. Review the person's responsibilities, experience, industry, and the size of the business. This benchmark can help make the amount defensible. Advisors experienced in audit and assurance services in Dubai can help businesses review relevant documentation and arrangements.

How Expense Classification Affects Small Business Relief Filers

Why SBR electors may not need a full taxable income calculation

Businesses that validly elect Small Business Relief may be treated as having no taxable income for the relevant tax period, subject to the applicable conditions. This can simplify the tax calculation, but clean expense classification and record keeping remain important for future periods and other compliance needs.

Revenue threshold is unaffected by deductible/non-deductible classification

The AED 3 million Small Business Relief revenue threshold is based on revenue under the relevant rules, not on whether individual expenses are deductible. Sales and other amounts that fall within the statutory revenue calculation need to be considered before deciding whether the threshold is met. Confirm eligibility against the rules for the specific tax period.

Record-keeping discipline even when the simplified return does not require every detail

Good records remain essential even where a simplified tax treatment is available. Whether you use IFRS for SMEs, cash-basis accounting where permitted, or accrual accounting, apply the relevant requirements consistently. Proper documentation helps the business respond if the FTA asks questions later.

Worked Calculation: From Accounting Profit to Corporate Tax Payable

Starting accounting profit

Every calculation begins with the appropriate accounting profit figure from the financial statements. It reflects the year's business activity under the applicable accounting framework. This starting number is then adjusted in the tax computation.

Confirming deductible expenses

Confirm that the deductible expense treatment is accurate and supported by evidence. Allowable expenses already included in accounting profit are not subtracted a second time. This step checks that no adjustment is needed for the category and that the amounts are properly recorded.

Adding back non-deductible expenses

Add back non-deductible expenses that reduced accounting profit but cannot reduce taxable income. Include the relevant amounts from the non-deductible categories and apply any required restrictions or apportionment. Other adjustments, exemptions, and reliefs may also affect the final figure.

Applying the AED 375,000 0% threshold and 9% rate to arrive at tax payable

Under the standard Corporate Tax rates, the first AED 375,000 of taxable income is subject to a 0% rate, and taxable income above that threshold is generally subject to a 9% rate. Multiply the portion above AED 375,000 by 9% to calculate the tax before considering other applicable reliefs, credits, or adjustments.

This example is for illustration only. The actual tax result depends on the taxpayer's circumstances, the nature of each adjustment, and the rules applicable to the relevant tax period.

Documentation and Audit Readiness Practices for Expense Classification

Maintaining separate ledgers for deductible vs. non-deductible items

Strong bookkeeping starts with clear records for each expense type. Expense classification records make year-end preparation faster and help reviewers identify adjustments. Consistent habits throughout the year prevent a last-minute scramble before filing.

Evidence requirements for entertainment, donations, and bad-debt write-offs

Every claimed deduction should have supporting documentation. Keep receipts and invoices for entertainment and donation expenses, along with evidence of business purpose and attendees where relevant. For bad debts, retain the customer account, collection records, and write-off approval. Missing documentation is a common source of audit questions.

Pre-filing review checklist against non-deductible categories

Before submitting your return, run a full pre-filing review. Check expenses against the relevant non-deductible categories and other adjustment rules under Corporate Tax Law. This step can catch errors before the return is finalised and reduce the need for later corrections.

When to escalate ambiguous classifications to a tax advisor

Some expenses will not fit neatly into either category. When this happens, seek advice rather than guessing. An ambiguous classification deserves a review of the facts, supporting records, and relevant legal provisions. This extra step can prevent costly mistakes.
