DUBAI, UAE, October 12, 2026 – Bestax Chartered Accountants, an accounting and tax advisory firm in Dubai’s Business Bay, is setting out the financial compliance rules UAE business owners must meet. Your next key deadline may be October 30, 2026. By then, in-scope businesses with revenue of AED 50 million or more must appoint an e-invoicing service provider.
Some of you face an earlier deadline. If your VAT tax period ended on September 30, your return and payment are generally due by October 28, 2026.
Corporate tax, VAT, e-invoicing, record keeping and anti-money laundering rules now overlap. When you handle each one separately, you are more likely to miss a deadline.
Below are the rules in force as of October 2026. We group them into tax, financial records and regulatory filings, and show the support Bestax can provide for each.
Tax Compliance: Corporate Tax, VAT and E-Invoicing
1. Corporate Tax
If your company is subject to corporate tax, you must register, whatever your revenue. Exempt persons have different obligations, depending on their category.
Did you incorporate a UAE resident company on or after March 1, 2024? You generally have three months to register. FTA Decision No. 3 of 2024 sets that deadline. Other categories have different registration dates.
You generally must file your return and pay your tax within nine months after your tax period ends. With a December year end, your deadline is September 30 of the following year.
| Corporate tax breach | Penalty under Cabinet Decision No. 75 of 2023, as amended |
| Late registration | AED 10,000, subject to any applicable waiver |
| Late return | AED 500 per month or part-month for the first 12 months, then AED 1,000 per month or part-month |
| Late payment | 14% a year on unpaid payable tax, calculated monthly for each month or part-month |
You can face a late filing penalty even if no tax is due. The late payment penalty applies only while payable tax remains unpaid.
You may not have to pay the late registration penalty. A waiver can apply if you file your first return within seven months after your first tax period ends.
Check whether you qualify. If you already paid the penalty and meet the waiver conditions, the amount can be credited to your EmaraTax account.
Under Ministerial Decision No. 131 of 2026, Small Business Relief now covers tax periods ending on or before December 31, 2029.
To claim it, you must be an eligible resident person with revenue of AED 3 million or less in the relevant tax period and all previous tax periods. You must elect the relief and still file a return.
Qualifying Free Zone Persons and certain multinational group members cannot claim it.
2. VAT
Your VAT obligations depend on your taxable supplies. The table shows when you must register and when you can choose to.
| Registration | When it applies |
| Mandatory (UAE-resident businesses) | Your taxable supplies and imports were above AED 375,000 over the past 12 months, or you expect them to pass that amount in the next 30 days |
| Voluntary | Your taxable supplies and imports, or eligible taxable expenses, were above AED 187,500 over the past 12 months, or you expect them to pass that amount in the next 30 days |
Non-residents follow different registration rules. You may need to register even if you have not reached the usual threshold.
You generally must file each VAT return and pay within 28 days after the tax period ends.
From April 14, 2026, Cabinet Decision No. 129 of 2025 changed VAT penalties. If you pay late, you now face a 14% annual penalty, calculated monthly on the unpaid tax.
An incorrect return attracts an AED 500 penalty. You avoid it if you correct the return before the filing deadline. You also avoid it if you submit a voluntary disclosure that does not change the amount of due tax.
Two laws changed VAT from January 1, 2026. Federal Decree-Law No. 16 of 2025 amended the VAT Law. Federal Decree-Law No. 17 of 2025 amended the Tax Procedures Law. Key changes for you:
- Five-year limit: You generally must claim excess recoverable tax as a refund, or use it, within five years. The period starts at the end of the tax period when the excess arose.
- Transitional relief (Federal Decree-Law No. 17 of 2025): You have until December 31, 2026 to claim a refund on some older tax credit balances. The relief covers qualifying balances whose five-year period expired before January 1, 2026, or expires within one year of that date. Check whether your balances qualify.
- Reverse charge: For concerned goods and services you import on or after January 1, 2026, the reverse-charge rules no longer require self-invoices. You must still keep supporting documents. Check any domestic reverse-charge arrangements separately.
3. E-Invoicing
Ministerial Decisions No. 243 and 244 of 2025 set out the e-invoicing rules and rollout. Ministerial Decision No. 66 of 2026 updated the first service-provider deadline.
The system covers in-scope business-to-business (B2B) and business-to-government (B2G) transactions. If you are subject to the system, you must appoint an Accredited Service Provider (ASP). Your ASP sends and receives structured e-invoices for you.
| In-scope business or entity | Appoint an ASP by | Go live by |
| Revenue of AED 50 million or more | October 30, 2026 | January 1, 2027 |
| Revenue below AED 50 million | March 31, 2027 | July 1, 2027 |
| Government entities | March 31, 2027 | October 1, 2027 |
The October 30 date replaced the original July 31, 2026 deadline. The January 1, 2027 implementation date did not change.
A PDF invoice sent by email is not a structured e-invoice. Your invoice data and accounting system must meet the new requirements.
Depending on the engagement, Bestax can confirm your tax accounts, prepare your corporate tax and VAT returns, and help map your invoice data before your ASP deadline.
When you work with a chartered accountant in Dubai, one team handles your corporate tax, VAT and e-invoicing compliance. Your records then stay consistent across every filing.
Financial Records: What You Must Keep and Prepare
1. Bookkeeping
Every tax return you file depends on accurate books. For corporate tax, you generally need financial statements and supporting records. For VAT, you need records of your sales, purchases and relevant tax adjustments.
If you leave all bookkeeping until year end, you can delay your year-end close. Bestax recommends monthly bookkeeping for VAT-registered businesses, so you find errors earlier.
For businesses managing employee salary payments, understanding how to check a UAE prepaid salary card balance can also support everyday financial recordkeeping.
2. Record Retention
You must keep records for a minimum retention period. Each period starts when the relevant tax period ends.
| Records | General minimum period | Source |
| Corporate tax records | Seven years after the relevant tax period ends | Corporate Tax Law, Article 56 |
| General VAT records | Five years after the relevant tax period ends | Tax Procedures Executive Regulation, subject to VAT rules |
| VAT records relating to real estate | 15 years after the relevant tax period ends | VAT Executive Regulation, Article 71 |
Longer retention can apply in some cases, such as audits or disputes. If you use a record for more than one tax, keep it for the longest applicable period.
If you fail to keep required corporate tax records, the penalty is AED 10,000. A repeat violation within 24 months attracts AED 20,000. Correct tax figures do not remove your duty to keep supporting records.
3. Audited Financial Statements
Ministerial Decision No. 84 of 2025 applies to tax periods starting on or after January 1, 2025. For those periods, it replaced Decision No. 82 of 2023.
You need audited financial statements if you are:
- a taxable person outside a tax group, with revenue above AED 50 million
- a Qualifying Free Zone Person
- a tax group (you must prepare audited special-purpose financial statements)
If you are a non-resident, the threshold considers revenue derived through UAE permanent establishments and/or nexuses.
Your free zone may set separate audit rules, including requirements linked to license renewal. Check your free zone’s rules before you renew.
Bestax can help maintain your books in systems such as Xero, QuickBooks, Zoho Books or Odoo. We agree record storage and retention duties with you in the engagement.
If you need an audit, Bestax can prepare your audit file and coordinate with an appropriately licensed auditor. The auditor issues the signed audit report.
Regulatory Filings: Ownership, AML and ESR
1. Beneficial Ownership Records
Cabinet Decision No. 109 of 2023 generally covers mainland companies and companies in commercial, non-financial free zones, subject to exemptions. DIFC and ADGM follow their own beneficial ownership rules.
If your company is covered, you must keep beneficial ownership records. You must also submit the required details to your registrar.
When ownership changes, you generally must record the change within 15 days of becoming aware of it. You must also provide updated details as required.
Banks and tax authorities may ask for your ownership information. Current records help you avoid conflicting answers.
2. Anti-Money Laundering
Federal Decree-Law No. 10 of 2025 replaced the 2018 AML law on October 14, 2025. Its executive regulation, Cabinet Resolution No. 134 of 2025, took effect on December 14, 2025.
The law covers designated non-financial businesses and professions (DNFBPs). If you are a covered DNFBP, you must register on goAML and appoint a compliance officer.
You must also meet the applicable duties for customer due diligence, record keeping and suspicious-activity reporting.
Relevant sectors include real estate, precious metals and stones, accountancy and corporate services. Your coverage depends on the activities you perform and the applicable transaction conditions.
Tax evasion can create exposure under both tax law and money-laundering law. We recommend you review your tax and AML records together.
3. Economic Substance Regulations
You may still be preparing ESR reports you no longer need. Under Cabinet Decision No. 98 of 2024, ESR notifications and reports are not required for financial years ending after December 31, 2022.
Earlier in-scope years remain subject to compliance obligations. For those years, you must address outstanding filings, information requests and applicable penalties.
For later years, the cancellation removes penalties and provides for refunds of amounts already paid, subject to the applicable process. The cancellation does not remove penalties for earlier in-scope years.
Bestax can check whether your activities bring you within the DNFBP rules, support your goAML registration where required, and help prepare your beneficial ownership records. We can also review whether earlier ESR obligations remain outstanding.
How Bestax Works With You
Bestax tailors its accounting, tax and compliance support to each engagement. The work can follow five steps:
- Compliance check. We review your trade license, tax accounts and the applicable rules. Then we prepare a calendar of your applicable deadlines.
- Tax agent appointment. If tax representation is included, we arrange the appropriate EmaraTax appointment.
- Monthly books. We maintain the agreed accounting records. We reconcile them with the figures used in your tax filings.
- Review before filing. We review each return and get your approval before submission.
- Post-filing support. If an error is found after filing, we assess it. Then we make the required corrections or disclosures.
A voluntary disclosure can reduce your penalties. If you make a qualifying voluntary disclosure before you are notified of a tax audit, you can avoid the fixed 15% tax-difference penalty. Other applicable penalties may still apply.
Before work starts, we agree the point of contact, reporting arrangements and fees with you. You remain responsible for providing complete records on time.
