UAE Regulatory Changes April 2026: What Changed?

In April 2026, the Ministry of Finance released an update to the Executive Regulation of the UAE Tax Procedures Law. The update highlights how certain tax procedures should be handled in practice, including record keeping, voluntary disclosures, credit balance refunds, confidentiality and the handling of documents or assets during tax audits.

For businesses, the UAE regulatory changes April 2026 are not about introducing a new tax. They are about making existing tax processes clearer and helping taxpayers understand what records, explanations and documents may be needed when dealing with the Federal Tax Authority, or FTA.

For business owners, finance teams and tax teams, the key point is simple: the better your records are, the easier it is to support your tax position. At WellTax, we see this update as a practical reminder for UAE businesses to check whether their tax records, refund files and FTA portal details are ready before a question or request arrives.

In this article, we explain what the UAE regulatory changes April 2026 are, why it matters and what UAE businesses should review now.

What changed under UAE regulatory changes April 2026?

The UAE regulatory changes April 2026 relates to Cabinet Decision No. 74 of 2023 on the Executive Regulation of the UAE Tax Procedures Law, as amended by Cabinet Decision No. 17 of 2026. The Ministry of Finance confirmed that the amendments relate to the updated Tax Procedures Law, which entered into force on 1 January 2026, while the Executive Regulation amendments took effect from 1 April 2026.

The amended procedures under the UAE regulatory changes April 2026 focus on five practical areas for taxpayers:

• Period of record keeping, which affects how long businesses may need to keep tax records, accounting documents and supporting files.
• Submission of voluntary disclosure, which applies when a business needs to correct certain tax errors in a return, assessment or refund claim.
• Seizure and retention of documents and assets, which relates to how the FTA may handle documents, records or assets during a tax audit.
• Credit balance refund procedures, which cover situations where a taxpayer has a credit balance that may be refunded or used against future tax liabilities.
• Confidentiality and disclosure of information, which explains how taxpayer information may be protected, shared or disclosed in specific cases.

The UAE regulatory changes April 2026 update did not introduce these tax procedure areas from scratch. Many of them were already part of existing tax procedure law. What changed is that the rules were clarified, extended or aligned with the amended Tax Procedures Law.

Below, we explain what each area means in practical terms.

Period of record keeping

Record keeping was already required under Cabinet Decision No. 74 of 2023. In general, taxable persons must keep accounting records, commercial books and supporting documents for five years after the relevant tax period. Real estate records generally need to be kept for seven years. Additional periods may apply in cases such as disputes, ongoing audits, FTA audit notices or voluntary disclosures.

The April 2026 update is important because it highlights record retention where a refund claim is still open. If a refund claim has been submitted and the FTA has not yet issued a decision, the related records may need to be kept for an additional two years.

For businesses, the key message is simple: do not close or delete refund files too early. Keep the documents behind the numbers, including invoices, contracts, ledgers, payment evidence, tax returns and calculation notes.

This is also why record keeping should not be treated as an admin task only. It is part of tax risk management. For more detail on what to keep, you can read our guide specifically on record-keeping documents for UAE corporate tax compliance.

Submission of voluntary disclosure

Voluntary disclosures were already part of the tax procedure rules. If a taxpayer finds that a tax return or tax assessment was incorrect and the tax payable was understated by more than AED 10,000, a voluntary disclosure must be submitted within 20 business days from the date the error was identified.

The April 2026 update is not a new voluntary disclosure requirement. Its purpose is to make the submission process clearer and align it with the amended Tax Procedures Law that has applied since 1 January 2026.

For businesses, the practical point is to act quickly and keep evidence. When an error is found, record:

• when the error was identified
• what caused it
• how much tax is affected
• which correction route will be used
• who reviewed and approved the decision

At WellTax, we help taxpayers review their position before a correction is submitted, so the business has a clear file supporting its approach.

Seizure and retention of documents and assets

The FTA already had powers under Cabinet Decision No. 74 of 2023 to inspect premises, documents, assets, electronic records and accounting systems during a tax audit. The rules also allow the FTA to copy, mark, seize or retain documents and assets where needed for audit purposes.

The April 2026 update does not state a fixed new period for keeping seized or preserved documents and assets. Instead, it introduces the possibility for that period to be extended where needed for a tax audit or examination. In practice, this means businesses should be ready for relevant documents or assets to remain under review for longer if the FTA considers this necessary.

For businesses, the practical point is readiness. Keep audit files clear, complete and easy to access, including tax returns, invoices, ledgers, contracts, bank evidence, correspondence and working papers. This makes it easier to respond if the FTA asks for documents or if certain records are retained during an audit.

Credit balance refund procedures

Credit balances and refund procedures were already also covered under Cabinet Decision No. 74 of 2023. If a taxpayer pays more than its existing liabilities, the excess may be treated as a credit against future liabilities unless the taxpayer requests a refund. The FTA may also allocate credit balances against amounts due.

The April 2026 update clarifies that refund procedures apply to credit balances in favour of the taxpayer.

For businesses, this means credit balances should be reviewed regularly. Before requesting a refund, check that:

• all relevant returns have been filed
• the credit balance agrees with accounting records
• the refund claim is supported by invoices, payment evidence and tax calculations
• FTA correspondence has been saved
• the internal tax account has been reconciled

For companies with open refund claims or old credit balances, this is a good time to check whether the figures are still accurate and whether the supporting documents are complete.

Confidentiality and disclosure of information

Confidentiality rules already existed under Cabinet Decision No. 74 of 2023. In general, FTA employees and authorised persons cannot disclose taxpayer information except in specific cases, such as disclosure to competent government authorities, disclosure under international agreements or disclosure requested by the taxpayer, legal representative or tax agent.

The April 2026 update clarifies how disclosure to competent government authorities should be handled. It confirms that taxpayer information may be shared only within defined rules, with limits on how the information can be used and with confidentiality protections still in place.

For businesses, the practical point is accuracy. Company names, licence activities, tax registration numbers, contact details, accounting records and EmaraTax details should match as much as possible. Small mismatches can create delays when a notice, refund review or document request is issued.

Why the UAE regulatory changes April 2026 matter to businesses

The UAE regulatory changes April 2026 matter because tax compliance is not only about filing a return before the deadline. It is also about keeping good records, making timely corrections and having clear internal responsibility for tax matters.

Many tax issues start with something small. A finance team may notice that a previous return included the wrong figure. A refund may be submitted before all supporting documents are ready. A company may change its licence activity or address but forget to update the tax records. These are everyday situations, but they can create risks of fines and penalties if they are not handled properly.

This is why we see the UAE regulatory changes April 2026 update as a practical reminder. Businesses should look at their tax process before there is a problem, not after a notice arrives.

The same approach applies to VAT updates and wider tax changes. UAE tax rules continue to develop, and businesses need a practical process for monitoring changes, updating records and applying new requirements. For related reading, see our article on UAE VAT changes every business should know.

Simple steps to stay prepared

The best way to deal with this update is to make small improvements now. We do not recommend waiting until a refund is delayed or a document request arrives. A short tax health check can make the business much more comfortable.

Start with these practical steps:

• Review open refund claims and make sure each one has a complete support file.
• Check tax credit balances and confirm that they agree with submitted tax returns.
• Create an error register so tax corrections are tracked from the first day they are noticed.
• Update FTA contact details in EmaraTax if your email, phone number, address or licence activity has changed.
• Prepare an audit folder for key tax periods, especially where refunds or corrections are involved.
• Agree internal responsibility so the right person monitors FTA messages and deadlines.

The main takeaway from the UAE regulatory changes April 2026 is that good tax compliance is built before there is a problem. When records are complete, errors are reviewed quickly and refund claims are supported properly, the business is in a stronger position.

At WellTax, we help businesses turn updates such as the UAE regulatory changes April 2026 into practical checks that finance teams can actually use. That can include reviewing records, checking refund files, assessing possible voluntary disclosures and preparing for FTA document requests.
