The UAE’s introduction of federal corporate tax in 2023 marked a historic shift for businesses across all emirates, including Abu Dhabi. This comprehensive tax regime, administered by the federal tax authority, now requires companies and qualifying individuals to navigate new filing requirements, deadlines, and compliance obligations.
Understanding how to file corporate tax in Abu Dhabi is crucial for maintaining good standing with the uae’s federal tax authority and avoiding significant penalties. Whether you operate a mainland company, free zone entity, or qualify as a taxable person through business activities, this guide provides the essential knowledge you need to successfully complete your corporate tax filing.
From registration requirements to document preparation, payment schedules to Abu Dhabi-specific considerations, we’ll walk you through every aspect of the corporate tax filing process to ensure your business remains compliant with uae corporate tax law.
Corporate Tax Filing Requirements in Abu Dhabi
The uae corporate tax regime applies uniformly across all emirates, including Abu Dhabi, under the federal tax authority fta. This system represents a fundamental change in how businesses operate and report their financial activities in the region.
Tax Rates and Thresholds
The uae corporate tax law establishes a progressive rate structure designed to support small and medium enterprises while generating federal revenue. Businesses with taxable income up to AED 375,000 benefit from a 0% tax rate, while profits exceeding this threshold face a 9% corporate tax liability.
This competitive rate structure maintains the UAE’s attractiveness as a business destination while ensuring compliance with international tax standards. For most Abu Dhabi businesses, calculating taxable income involves starting with net profits from audited financial statements and making specific adjustments according to federal tax regulations.
Who Must File Corporate Tax Returns
All taxable persons must file corporate tax returns, regardless of whether they owe tax. This includes:
Juridical persons: Companies, partnerships, and other legal entities registered in Abu Dhabi
Natural persons: Individuals conducting business activities with annual turnover exceeding AED 1 million
Free zone persons: Entities operating in Abu Dhabi free zones, even those qualifying for 0% rates
Foreign entities: Companies with permanent establishments or UAE-sourced income
The federal tax authority requires filing even when no tax liability exists, making compliance mandatory for all qualifying entities and individuals.
Filing Deadlines and Online Requirements
Corporate tax returns must be filed within nine months after the end of the relevant tax period. For businesses with financial years ending December 31, 2024, the filing deadline is September 30, 2025. The federal tax authority mandates exclusive use of the emaratax portal for all submissions, eliminating paper-based filing options.
This digital-first approach streamlines the process while ensuring the federal tax authority fta can efficiently process and monitor compliance across all emirates, including Abu Dhabi.
Step-by-Step Process to File Corporate Tax in Abu Dhabi
Successfully filing corporate tax returns requires systematic preparation and attention to detail. The process involves several interconnected steps, from initial registration through final submission and payment.
Registration with Federal Tax Authority
Before filing your first corporate tax return, you must register with the federal tax authority to obtain a tax registration number. This process applies to all taxable persons, including those already registered for VAT purposes.
Registration Timeline and Requirements
The registration process typically takes 20 business days from submission of complete documentation. However, you should initiate registration well before the deadline to avoid potential delays that could result in penalties.
To register for corporate tax, you’ll need:
Valid Abu Dhabi trade license
Emirates ID for authorized signatory
Memorandum and articles of association (for companies)
Board resolution authorizing tax registration
Power of attorney if using a tax agent
Obtaining Your Tax Registration Number (TRN)
Upon successful registration, the federal tax authority issues a unique tax registration number that you’ll use for all corporate tax filing activities. This TRN links your business to your tax obligations and enables access to the emaratax portal.
If you already hold a TRN for VAT purposes, you can use the same number for corporate tax, simplifying the administrative process.
Creating Your EmaraTax Portal Account
The emaratax portal serves as your primary interface with the federal tax authority for all corporate tax matters. Setting up your account requires your TRN and authorized user credentials.
Navigate to the official emaratax portal and complete the user registration process. You’ll need to verify your identity and link your account to your business’s TRN. The system allows multiple users per business, enabling delegation of filing responsibilities while maintaining security controls.
Preparing Financial Statements and Supporting Documentation
Accurate financial statements form the foundation of your corporate tax return. The federal tax authority accepts both audited and management accounts, depending on your business size and structure.
Your financial statements must include:
Income statement showing revenues and expenses for the tax period
Balance sheet reflecting assets, liabilities, and equity
Cash flow statement detailing cash movements
Notes explaining accounting policies and significant transactions
Ensure your accounting records align with International Financial Reporting Standards (IFRS) or other acceptable accounting frameworks. Discrepancies between your financial statements and tax return require detailed explanations and supporting documentation.
Completing the Corporate Tax Return Form
The online corporate tax return form guides you through required information sections:
Basic Information Section
Business details and tax registration information
Reporting period and financial year end date
Contact information for tax correspondence
Income and Expense Reporting
Gross income from all sources
Deductible business expenses
Non-deductible items per uae tax laws

Submitting the Return and Making Payment

After successful submission, the system generates a confirmation receipt with your submission reference number. Retain this documentation for your records as proof of timely filing.
Payment Process
Corporate tax payments can be made through various methods accepted by the federal tax authority:
Online banking transfer through the emaratax portal
Bank branch payments using federal tax authority payment slips
Authorized payment service providers
Ensure payment reaches the federal tax authority by the due date to avoid interest charges and penalties.

Your Abu Dhabi trade license provides fundamental information about your business activities and legal structure. Ensure your license remains current and accurately reflects your actual business operations, as discrepancies can trigger federal tax authority inquiries.
For companies, include memorandum and articles of association, along with any amendments made during the tax period. Partnership agreements, establishment cards, and other formation documents provide additional context for your business structure.

Filing Deadlines and Payment Schedule
Understanding and meeting corporate tax deadlines is crucial for maintaining compliance and avoiding penalties. The federal tax authority has established clear timelines that apply to all taxable persons in Abu Dhabi and across the UAE.
Nine-Month Filing Deadline
Corporate tax returns must be filed within nine months after the end of your financial year. This generous timeline accommodates the complexity of preparing comprehensive tax returns and obtaining necessary approvals.
Specific Deadline Examples:
Financial year ending December 31, 2024: File by September 30, 2025
Financial year ending March 31, 2024: File by December 31, 2024
Financial year ending June 30, 2024: File by March 31, 2025
The federal tax authority does not grant automatic extensions, making timely preparation essential for meeting these deadlines.
Tax Payment Due Dates
Corporate tax payments follow the same nine-month schedule as return filing. However, the federal tax authority may introduce installment payment options for businesses with significant tax liabilities.
Payment must be received by the federal tax authority, not merely initiated, by the due date. Allow sufficient time for payment processing, especially for international wire transfers or complex payment arrangements.

Additional AED 500 for each subsequent month

Rate determined by the federal tax authority fta
Compounded monthly until full payment
Administrative Consequences
Potential federal tax authority audit
Increased scrutiny on future filings
Difficulty obtaining tax clearance certificates
Impact on business license renewals
Extension and Voluntary Disclosure Options
While automatic extensions aren’t available, the federal tax authority may consider exceptional circumstances that prevented timely filing. Submit extension requests with supporting documentation before the original deadline.
The voluntary disclosure program allows businesses to correct errors or omissions from previous filings with reduced penalties, provided disclosure occurs before federal tax authority investigation begins.
Penalties and Compliance Requirements
The federal tax authority enforces strict compliance standards to ensure effective administration of the uae corporate tax regime. Understanding penalty structures and compliance requirements helps businesses avoid costly violations and maintain good standing.
Registration Penalties
Failure to register for corporate tax when required triggers substantial penalties:
