1. The “CT-VAT Mismatch” (The 2026 Primary Trigger)

In 2026, the FTA’s discrepancies between revenue reported in Corporate Tax returns and VAT filings may attract closer scrutiny from the FTA as part of its compliance review process.

• The Flag: If your reported revenue in your CT return (Form CT-1) is higher than the sum of your four quarterly VAT returns, the “Risk Engine” flags it as potential under-reporting of VAT.
• The 2026 Risk: Under Federal Decree-Law No. 17 of 2025, the FTA may now demand a full reconciliation.

2. Claiming “Legacy” VAT Credits (The 5-Year Expiry Rule)

As of January 1, 2026, a strict five-year time limit governs all VAT refund claims.

• The Flag: Filing a refund application for credits that originated in 2020 or early 2021.
• The 2026 Risk: The FTA views these “last-minute” claims with high suspicion. Attempting to recover old credits during the transitional window (closing Dec 31, 2026) often may trigger a “Reconciliation Audit” to verify the original source of the input tax from five years ago.

3. Frequent “Voluntary Disclosures” (The Systemic Error Flag)

While the 2026 framework has reduced penalties for Voluntary Disclosures (VDs) to encourage honesty, frequent VDs may signal a lack of internal controls.

• The Flag: Submitting more than two VDs in a single calendar year.
• The 2026 Risk: The FTA may categorize such businesses as “High Risk,” and suspect that your bookkeeping is reactive rather than compliant.

4. Breaching the “AED 3 Million SBR Cliff”

The Small Business Relief (SBR) is only available for tax periods ending on or before December 31, 2026, provided revenue stays below AED 3 million.

• The Flag: Reporting exactly AED 2.9 million or showing a sudden, unexplained drop in revenue to stay under the threshold.
• The 2026 Risk: The FTA may specifically audit SMEs near the “cliff” to ensure revenue hasn’t been split between sister companies—a violation of the Anti-Abuse rules in the Corporate Tax Law.

5. Related Party Transactions without TP Documentation

With the first Corporate Tax returns due for many in September 2026, intercompany dealings are under the microscope.

• The Flag: Significant management fees, interest-free loans, or “office sharing” costs between related entities without a Transfer Pricing (TP) Local File.
• The 2026 Risk: Unsubstantiated transactions can be disallowed, leading to a 9% tax hit plus a 14% annual interest penalty on the unpaid tax under the new 2026 unified penalty structure.

6. Manual “Self-Invoicing” Errors (Post-EIS Pilot)

The Electronic Invoicing System (EIS) pilot begins in July 2026.

• The Flag: While the 2026 VAT amendments removed the requirement to “self-issue” invoices for Reverse Charge imports, your books must still perfectly match the customs data from the Federal Customs Authority.
• The 2026 Risk: Inconsistencies between the “Goods Import” data in the FTA portal and your accounting ledger are now an automatic trigger for a “Desk Audit.”

7. “Miscellaneous” and “Entertainment” Expense Bloat

In 2026, the FTA is focusing on “non-deductible” expenses that businesses try to slip into their CT returns.

• • The Flag: Entertainment expenses that exceed the 50% deduction limit or large “Miscellaneous” categories without supporting tax invoices.
  • The 2026 Risk: Under Ministerial Decision No. 84 of 2025, documentation for these must be “contemporaneous.” If you can’t produce a valid tax invoice during a spot check, the expense is added back to your profit, and a record-keeping penalty of AED 10,000 is applied.
