Post audit procedures in the UAE explained step by step

What are post audit procedures in the UAE?

Post audit procedures UAE refers to the steps that follow once the Federal Tax Authority (FTA) closes the on-site or desk review phase of a tax audit. They cover the audit results notice, any tax assessment, penalty notices, payment deadlines, objection and reconsideration rights, and the corrective actions a business must take to align its records and filings.

Most UAE businesses focus on getting through the audit itself. The post audit stage is where the legal and financial impact lands. Understanding the timelines, your rights, and the paperwork helps you respond on time and protect cash flow. This guide sits inside our FTA Compliance UAE hub and walks through each stage in plain English.

The official close of an FTA audit

An FTA audit does not end with the auditor leaving your office. It ends when the FTA issues a formal audit results notice. This notice tells you whether the audit found any shortfall, overpayment, or no change to your filings.

Audit results notice

The FTA must inform you of the audit outcome within 10 business days of completion. The notice sets out the scope, the periods reviewed, and the conclusions. If everything matches your filings, the file closes. If not, the notice usually arrives with, or is followed by, a tax assessment.

Tax assessment and penalty notices

If the FTA finds underpaid tax, it issues a Tax Assessment under Federal Decree-Law 17 of 2024 on tax procedures. An Administrative Penalties Assessment may follow for late filing, late payment, or incorrect returns. Read our walkthrough of the FTA Tax Assessment Process for the full mechanics.

What the notice contains

• The tax periods covered.
• The additional tax due, if any.
• The administrative penalties applied.
• The legal basis cited by the FTA.
• The payment deadline and your objection rights.

Payment deadlines after an audit

Once a Tax Assessment is issued, the clock starts. You must settle the tax and any penalties within 20 business days of receiving the notice. Missing this window adds further late payment penalties on the outstanding balance.

How payments are applied

The FTA applies payments in a set order: administrative penalties first, then tax due, then late payment penalties. This matters when you make a partial payment, because it changes how interest and penalty accruals stop.

Installment requests

If the assessed amount creates a cash flow problem, you can apply for an installment plan through the FTA portal. Approval is discretionary and usually requires proof of financial hardship and a clear repayment schedule.

Your right to challenge the assessment

Receiving a Tax Assessment does not mean the matter is closed. UAE tax law gives every registrant a structured route to challenge findings.

Step 1: Reconsideration request

You can ask the FTA to reconsider its decision within 40 business days of being notified. The request must be in Arabic, supported by evidence, and submitted through the FTA portal. The FTA has 40 business days to respond.

Step 2: Tax Disputes Resolution Committee (TDRC)

If the reconsideration outcome is unfavourable, you can escalate to the TDRC within 40 business days of the FTA's reply. The committee reviews the file independently and issues a binding decision, subject to court appeal.

Step 3: Federal Courts

TDRC decisions can be appealed to the Federal Court of First Instance within 40 business days. This step is rare for most small and mid-sized UAE businesses, but it remains an option.

Timeline at a glance

Penalty ranges you may face

Penalties depend on the violation type. They are set out in Cabinet Decisions on administrative penalties for VAT, excise, and corporate tax, and in Cabinet Decision 106 of 2025 for e-invoicing breaches.

Common post audit penalties

The exact figures and caps are set out in the relevant Cabinet Decisions on the UAE Ministry of Finance and Federal Tax Authority websites.

Corrective actions inside your business

The post audit phase is also when you fix the root causes the auditor flagged. Doing this well reduces your risk in the next cycle and limits exposure if the FTA returns. Our guide on how to prepare for FTA audit explains the controls to put in place.

Update your tax records

Adjust your accounting entries to reflect the audited position. Post correcting journals in the period the FTA assessed, not the current period, unless the assessment itself says otherwise.

Refile or amend returns where needed

If the audit found errors in returns that were not covered by the assessment, you may need to file voluntary disclosures. A voluntary disclosure is required when an error exceeds AED 10,000 and was not corrected in a later return.

Fix the underlying process

• Review how invoices were captured and coded.
• Check VAT treatment on zero-rated and exempt supplies.
• Reconcile the trial balance to filed VAT and corporate tax returns.
• Tighten document retention so the right FTA audit document set is always available.

Train the finance team

Most post audit findings trace back to a small number of process gaps. A short briefing for the team covering the specific issues the FTA raised is usually more effective than a generic refresher.

Record keeping after the audit closes

UAE tax law requires registrants to keep records for at least 5 years after the end of the tax period, and 7 years for real estate. The post audit phase is a good moment to check that your archive meets this rule.

What to retain

• Sales and purchase invoices.
• Credit and debit notes.
• Import and export documents.
• Bank statements and payment proofs.
• VAT and corporate tax return workings.
• Audit correspondence and the FTA's notices.

Format and access

Records can be electronic, but they must be readable, complete, and produced on request. Keep audit correspondence in a separate folder so any future review starts from a clean base.

How the audit outcome affects future filings

An audit outcome often changes how you treat similar transactions going forward. Update your tax positions, document the rationale, and disclose any change of approach in your next return where appropriate.

Watch for follow-up reviews

The FTA may revisit the same business if the assessed risks recur. Knowing what triggers FTA audit UAE activity helps you avoid the same red flags. Patterns the FTA monitors include late filings, large refund claims, and frequent voluntary disclosures.

Audit vs investigation

If the FTA suspects deliberate evasion, it can move from an audit to a tax investigation. The two routes have different powers and different consequences. See FTA Investigation vs Audit for a side by side view.

A practical post audit checklist

1. Read the audit results notice in full and note every deadline.
2. Compare the assessment to your own working papers line by line.
3. Decide on payment, reconsideration, or both within the 20 and 40 business day windows.
4. Post correcting journals and reconcile to the FTA's figures.
5. File any required voluntary disclosures for unrelated errors found.
6. Update process notes and train the finance team.
7. Verify that your record archive covers the 5 to 7 year retention rule.
8. Diary the date when the assessed periods become time-barred.
