As of September 3, 2026, UAE business owners are managing several important tax and regulatory developments at the same time. The immediate priority is the September 30 Corporate Tax deadline for businesses with financial years ending December 31, 2025. At the same time, qualifying SMEs have received welcome clarity through the extension of Small Business Relief UAE until December 31, 2029.
Large multinational groups must also assess new Pillar Two reporting requirements, while all taxable businesses should prepare for new supplier and transaction verification procedures taking effect on October 1, 2026.
These changes create practical questions:
- Does our business need to file a Corporate Tax return by September 30?
- Can we continue using Small Business Relief?
- Is our UAE entity affected by Pillar Two?
- What evidence will we need before claiming input VAT?
- What should we do with old refundable VAT balances?
As a professional business consultancy Dubai partner, we help businesses convert regulatory updates into clear, manageable actions. This September compliance guide explains what has changed and what business owners should do now.
How to Meet the September 30 Corporate Tax Deadline
Businesses with financial years ending on December 31, 2025 must file their Corporate Tax return and settle any Corporate Tax liability through EmaraTax by September 30, 2026.
The deadline generally falls nine months after the end of the relevant tax period. Therefore, a company using the calendar year as its financial year has a filing and payment deadline of September 30, 2026, for the 2025 tax period.
The Federal Tax Authority has urged taxpayers to file early rather than waiting until the final days. This is important because late filing, late payment, technical issues, missing documents, and unanswered EmaraTax queries can all create avoidable compliance pressure.
Businesses should complete the following steps immediately:
- Confirm the company’s financial year-end.
- Verify that Corporate Tax registration has been completed.
- Finalize the 2025 financial statements and accounting records.
- Reconcile revenue, expenses, bank statements, receivables, and payables.
- Review deductible and non-deductible expenses.
- Assess whether the company qualifies for any applicable relief or special regime.
- Prepare the Corporate Tax computation.
- File the return through EmaraTax.
- Pay the liability by September 30, if any amount is due.
- Save the submitted return, payment confirmation, and supporting calculations.
Our UAE VAT registration and Corporate Tax compliance service supports businesses with CT registration UAE, taxable income calculations, return preparation, Small Business Relief elections, and FTA correspondence.
A common mistake is assuming that a business does not need to file because its taxable income is low or because it expects to pay no tax. Filing obligations and payment obligations are separate issues. A company may have no Corporate Tax payable while still needing to submit its return within the prescribed deadline.

How to Use Small Business Relief Until 2029
The Ministry of Finance has extended Small Business Relief to tax periods ending on or before December 31, 2029. The extension is provided under Ministerial Decision No. 131 of 2026.
This is significant for qualifying resident businesses that were planning for the relief to end after tax periods ending on or before December 31, 2026.
The main conditions remain important:
- The business must generally be a UAE resident person for Corporate Tax purposes.
- Revenue must not exceed AED 3 million in both the current and previous tax periods.
- The relief must be elected for each applicable tax period.
- The business is treated as having no taxable income for the relevant period when the election is validly made.
- A Qualifying Freezone Person cannot elect for the relief.
- A member of a multinational enterprise group above the relevant revenue threshold cannot elect for the relief.
- The arm’s length principle still applies, even where transfer pricing documentation is not required under the relief.
The extension does not mean that every small business automatically receives zero Corporate Tax. Eligibility must be reviewed based on revenue history, legal status, ownership, group relationships, and the company’s tax position.
Businesses should also remember that Small Business Relief does not remove the need for proper records. Revenue should be supported by invoices, bank records, contracts, and accounting reports. The FTA has confirmed that eligible taxpayers must still submit simplified Corporate Tax returns within the prescribed legal deadline.
For a company with a December 31, 2025 year-end, the September 30, 2026 filing date remains relevant even if the company intends to elect for relief. The election should be reflected correctly in the return rather than assumed informally.
How to Assess Whether Pillar Two Applies
Pillar Two introduces a global minimum tax framework for large multinational enterprise groups. In the UAE, the Domestic Minimum Top-Up Tax applies to UAE constituent entities of MNE groups with consolidated annual revenues of at least EUR 750 million in at least two of the four preceding financial years.
The UAE Domestic Minimum Top-Up Tax applies to relevant financial years starting on or after January 1, 2025. The Ministry of Finance provides further details through its UAE Top-up Tax guidance.
For most locally owned SMEs, this development will not create a new reporting obligation. However, UAE subsidiaries, branches, holding companies, and operating entities connected to major international groups should not assume that the standard 9% Corporate Tax framework is the only relevant regime.
Ministerial Decision No. 133 of 2026 specifies which entities are required to file the Pillar Two Information Return for the purposes of Cabinet Decision No. 142 of 2024.
Businesses that may be within scope should take the following actions:
- Confirm the group’s consolidated revenue for the previous four financial years.
- Identify every UAE constituent entity and permanent establishment.
- Determine which entity is responsible for the information return.
- Confirm whether the group has a qualifying filing arrangement in another jurisdiction.
- Gather financial accounting, payroll, tangible asset, and covered tax data.
- Review safe harbour eligibility and transitional rules.
- Establish a documented process for group-level data collection.
- Confirm the relevant 15-month filing deadline, or the 18-month first-year deadline where applicable.
Pillar Two reporting is not a substitute for ordinary corporate tax UAE compliance. A UAE entity may need to comply with Corporate Tax, VAT, transfer pricing, financial reporting, and Pillar Two requirements separately.
How to Prepare for the October VAT Verification Rules
From October 1, 2026, FTA Decision No. 13 of 2026 will introduce measures requiring taxable persons to verify the validity and integrity of supplies before deducting input tax.
The official FTA Decision No. 13 of 2026 focuses on supplier and transaction verification. The purpose is to help prevent input tax recovery connected with transactions involving tax evasion.
A valid tax invoice and supplier Tax Registration Number remain important, but they may not be sufficient in higher-risk circumstances. Businesses should be able to demonstrate that they performed reasonable checks before claiming input VAT.
The procedures include:
- Verifying the supplier’s identity and incorporation details.
- Confirming the identity of an authorized director, agent, or employee.
- Checking that the supplier has a genuine place of business.
- Confirming that the supplier’s premises are consistent with its licensed activity.
- Reviewing risk indicators such as frequent address or key personnel changes.
- Assessing whether the transaction has a genuine commercial purpose.
- Reviewing the payment method and payment destination.
- Confirming that prices and margins are commercially reasonable.
- Checking whether the goods or services fall within the supplier’s ordinary licensed activities.
- Verifying the authenticity and origin of goods where relevant.
- Retaining evidence of the checks performed.
- Maintaining a written internal policy that assigns responsibility for supplier verification.
The decision includes thresholds that businesses should build into their procurement controls:
- Supplies below AED 10,000 excluding VAT may qualify for an exception from the prescribed measures.
- That exception does not apply if total supplies from the same supplier exceed, or are expected to exceed, AED 100,000 over the relevant 12-month period.
- Where supplies from a supplier exceed, or are expected to exceed, AED 375,000 over the relevant 12-month period, additional checks include confirmation of a UAE bank account and a review of reliable public recommendations or media coverage.
This means that procurement, accounts payable, finance, and tax teams should work from the same supplier risk policy. A VAT filing Dubai process that only checks invoices at quarter-end may not be sufficient after October 1.

How to Manage Excess Refundable VAT and Reverse Charge Records
Businesses should also review two VAT changes that became relevant from January 1, 2026. These changes are separate from the supplier verification rules in FTA Decision No. 13 of 2026.
First, excess refundable VAT may generally be carried forward for a maximum of five years from the end of the tax period in which the excess arose. Businesses must claim a refund or apply the balance against VAT liabilities before the applicable five-year period expires.
Any balance approaching the relevant limitation date should be reviewed now. Where a balance is required to be claimed or applied by December 31, 2026, the business should complete the process before the end of the year rather than waiting for the final weeks.
We recommend preparing a VAT credit schedule showing:
- The tax period in which each excess balance arose.
- The amount carried forward.
- Any amounts already offset.
- Any refund claims submitted.
- The remaining balance.
- The date on which the five-year period expires.
- The action required before the deadline.
Second, self-invoicing for certain reverse charge transactions is no longer required in the same way as before. However, businesses must continue to account for reverse charge VAT correctly and retain supporting documentation, such as supplier invoices, customs declarations, contracts, and import records.
The removal of a self-invoice does not remove the underlying record-keeping requirement. Businesses should update their accounting software and VAT procedures so that output tax and input tax are recorded accurately without creating unnecessary duplicate documents.
How to Update Records for a New or Existing UAE Business
Regulatory readiness should begin before a company’s first tax deadline. New businesses should consider tax registration, bookkeeping, banking records, and commercial substance when selecting their structure and operating model.
For founders evaluating company formation UAE options, our business formation support covers mainland and freezone structures, licensing, corporate documentation, and initial compliance planning. Selecting a suitable structure can help establish clearer records from the beginning.
Existing businesses should review whether their:
- Trade licence activities match their actual operations.
- Invoices show the correct legal name and tax information.
- Bank transactions reconcile with accounting records.
- Supplier contracts support the commercial purpose of payments.
- VAT and Corporate Tax registrations are accurate.
- Shareholder and beneficial ownership information is current.
- Financial statements can support the tax return.
- Internal approval procedures are documented.
Tax compliance can also affect banking and funding. Banks increasingly ask for tax registrations, financial statements, management accounts, and explanations of business activity during KYC reviews. Businesses that need stronger documentation for a UAE business account opening can benefit from preparing their records before submitting an application.
Similarly, a company considering a business loan in the UAE should maintain clean bank statements, accurate financial information, and evidence of compliant operations. Tax readiness strengthens financial credibility and supports more efficient discussions with banks and lenders.

How to Get Expert Business Support
September 2026 requires action, not speculation. Calendar-year businesses should prioritize the September 30 Corporate Tax filing immediately. Qualifying SMEs should verify their Small Business Relief election rather than assume the extension applies automatically. Large groups should determine whether Ministerial Decision No. 133 of 2026 creates a Pillar Two reporting obligation. All taxable businesses should begin building supplier verification and VAT evidence procedures before October 1.
