UAE tightens tax procedures, extends refund-linked record-keeping by two years
Corporate tax teams must keep records longer and follow stricter disclosure rules
Change
UAE's Ministry of Finance implemented revised tax procedures effective April 1, 2026, tightening voluntary-disclosure rules, applying refund procedures to any taxpayer credit balance, and extending record-retention by two years for tax periods linked to refund claims.
Why it matters
The amendments define and limit how tax information may be shared with competent authorities while reaffirming confidentiality protections. Expect more formal information requests tied to refund claims, increasing documentation requirements and likely lengthening audit timelines.
Implications
- — Corporate tax compliance teams at UAE-headquartered companies must update record-retention schedules and document workflows immediately — failure to produce the extended records during audits risks denial or delay of refund claims and potential penalties.
- — Tax advisory firms and external auditors serving UAE clients must revise engagement scopes and voluntary-disclosure checklists now — clients without aligned disclosure procedures face a higher risk of penalties or lost relief during audit examinations.
