UAE’s New Tax Procedures Law
January 4, 2026
Amendments include five‑year refund deadline and expanded FTA powers
Introduction
On 1 January 2026, the United Arab Emirates formally implemented major amendments to its Tax Procedures Law (Federal Decree‑Law No. 17 of 2025) and the VAT Law (Federal Decree‑Law No. 16 of 2025).
These reforms alter key aspects of how taxes are administered, moving the UAE’s procedural framework closer to international standards while strengthening compliance certainty for taxpayers.
Central to the reforms is the introduction of a five‑year statutory limitation period for claiming VAT refunds and credit balances, a first for the UAE, alongside amplified audit powers for the Federal Tax Authority (FTA), extended assessment windows, and clarified procedural rights and obligations for businesses.
What Has Changed?
The Five‑Year Refund Deadline
Historically, UAE businesses could hold excess input VAT credits indefinitely, carrying forward balances until they chose to claim refunds or offset future liabilities. Under the revised law:
Taxpayers must submit refund requests or utilise excess credit balances within five years of the end of the relevant tax period. After this deadline, credits expire and cannot be claimed.
A transitional relief period applies to legacy credits that would otherwise expire at the start of 2026: taxpayers have until 31 December 2026 to claim credits already older than five years.
This deadline applies not only to VAT but also to credit balances arising under corporate tax and excise tax when applicable. It requires systematic internal tracking of tax credit ledger balances by period.
Expanded Audit and Assessment Powers
The amendments significantly expand the FTA’s procedural authority:
The standard audit limitation period remains five years, but in specific risk scenarios — particularly suspected fraud or evasion — the FTA can conduct audits or issue assessments up to 15 years after the end of the relevant tax period.
The authority to issue binding tax interpretations and directives means consistent application of law across taxpayers and FTA officers, reducing interpretive uncertainty.
Refund claims submitted within the five‑year window can trigger extended audit exposure for prior years, effectively reopening historical periods.
Combined, these changes elevate the importance of robust documentation routines and proactive tax governance.
Anti‑Evasion and Compliance
Parallel amendments to the VAT Law empower the FTA to deny input VAT recovery where the supply chain involves transactions tied to tax evasion anywhere in the chain, placing greater onus on taxpayers to perform supplier due diligence ahead of claiming recoveries.
Practical Impacts on UAE Businesses
From a technical planning perspective, several implications emerge:
- Cash‑flow and working capital: The five‑year refund deadline transforms input VAT credits from an indefinite asset into a time‑constrained one. Companies must now forecast refund windows as part of working capital planning.
- Compliance systems: Entities with long‑standing credit balances from capital‑intensive activities (e.g., real estate or export‑oriented sectors) must prioritise older periods before they expire.
- Audit readiness: With extended audit reach, maintaining contemporaneous records for at least the last 15 years in high‑risk scenarios becomes essential.
Conclusion
The UAE’s 2026 tax procedural amendments are not superficial paperwork changes. Instead, they reshape tax administration by introducing hard deadlines and enforcement mechanisms familiar in mature tax systems.
While the corporate tax rate remains unchanged, the procedural environment now demands far greater rigour.
Final thoughts
For many companies, proactive tax governance will be the difference between a smooth compliance experience and costly retroactive disputes. Early engagement with the new rules will unlock certainty and minimise unexpected financial impact.
CALL TO ACTION
Carry out a VAT credit ageing analysis immediately, prioritise refund or offset claims approaching the five‑year limit, and strengthen supplier due‑diligence processes to support future input VAT recoveries.

Is Dubai still safe in 2026? Explore how Iran tensions are affecting UAE relocation decisions and what HNWIs should consider before moving.
Dubai continues to attract high-net-worth individuals from the UK and around the world. Its tax efficiency, strong infrastructure and international business environment make it an appealing base for both personal wealth and global business operations. However, relocating or investing in Dubai without proper planning can lead to costly mistakes. Understanding the legal, financial and cultural environment before making decisions is essential. Below are some of the most common pitfalls HNWIs should avoid when relocating to Dubai in 2026... Overlooking Tax Planning A common misconception is that living in Dubai means there are no tax considerations. While the UAE has no personal income tax, the regulatory environment has evolved in recent years. The introduction of UAE corporate tax, VAT and international tax reporting requirements means individuals with businesses, investments or global income streams still need structured tax planning. Those relocating from the UK must also consider the implications of the Statutory Residence Test, potential split-year treatment and double taxation agreements. Failing to structure finances properly before relocating can create unnecessary tax exposure in multiple jurisdictions. Rushing Property Investments Dubai’s real estate market offers strong opportunities, but it also requires careful due diligence. Off-plan property purchases in particular should be approached cautiously. Buyers should review the developer’s track record, financial strength and delivery history. Market cycles are also important to consider, especially as increased supply in certain areas could lead to price corrections in the future. Taking time to assess location, developer credibility and long-term demand helps protect capital and avoid poorly performing investments. Underestimating the Real Costs of Property Ownership The advertised purchase price is only part of the financial commitment when buying property in Dubai. Investors should also factor in: The Dubai Land Department (DLD) transfer fee of 4% Ongoing service charges for buildings or communities Maintenance and management costs Ignoring these costs can significantly impact overall investment returns. Failing to Prepare for Banking Requirements Opening bank accounts in the UAE can be more complex than many expect, particularly for international clients. Banks require extensive documentation to comply with international anti-money laundering regulations. If financial structures or documentation are unclear, accounts can be delayed, restricted or even frozen. Ensuring all financial arrangements are transparent and properly structured before relocation makes the process significantly smoother. Misunderstanding Residency and Visa Options Many individuals assume residency can be arranged later or through temporary arrangements. In reality, visa planning should be part of the relocation strategy from the outset. For example, long-term residency options such as the UAE Golden Visa have specific investment and eligibility criteria. Understanding these requirements early allows individuals to structure investments and assets accordingly. Ignoring Local Laws and Regulations Dubai is known for its safety and order, but this is supported by a strict legal framework. Actions that might be overlooked elsewhere, such as offensive language, inappropriate social media content or public intoxication, can carry significant legal consequences. Financial transactions and business activities are also closely regulated. Taking time to understand the legal environment helps avoid unnecessary issues. Underestimating Cultural and Lifestyle Differences Dubai is an international city, but it operates within a framework of local customs and expectations. Respect for public behaviour, dress standards in certain locations and cultural sensitivity are all important. Practical factors such as the extreme summer climate can also affect lifestyle choices and property decisions. Understanding these aspects helps individuals settle comfortably and avoid unnecessary challenges. How Mosaic Chambers Group Can Help Relocating to Dubai is rarely just about moving location.
