The Federal Tax Authority (FTA) frequently identifies recurring VAT non-compliances during audits. This guide outlines the most common issues, explains the applicable rules with examples, and provides practical steps organizations can take to ensure compliance.
Why this matters?
Since VAT was introduced on 1 January 2018, VAT law, guidance and FTA activity have evolved rapidly. The FTA has issued numerous guides, public clarifications and private rulings and audit activity has increased. Small mistakes made early in the VAT regime can accumulate into large tax liabilities and penalties because VAT applies retrospectively from the start of the regime.
Quick Summary of the Most Frequent Non‑compliances
- Incorrect treatment of transitional transactions (contracts entered before 1 Jan 2018 that extend into the VAT period)
- Wrong classification of supplies (zero‑rated vs standard, or out‑of‑scope vs standard)
- Misapplication of intra‑group, designated zone and mainland rules (incoterms matter)
- Failure to recognize tax obligations based on legal ownership (disclosed vs undisclosed agency)
- Poor documentation (missing exit certificates, incorrect invoice format, lack of supporting transport/shipping proof)
- Reconciliation differences between financial statements and VAT returns
1. Transitional Provisions: Capture VAT on Contracts that Cross 2018
Article 80 of the Decree‑Law governs transitional transactions: any supply entered into before 1 January 2018 that continues into the VAT period must be assessed to determine the VAT due on the portion of the supply that falls inside the VAT period.
Common errors:
- Failing to identify long‑term contracts (real estate, construction, projects) as transitional
- Booking VAT incorrectly on the whole contract instead of apportioning the VAT‑able portion.
2. Incorrect Classification of Transactions
Classification errors are pervasive. VAT treatment depends on:
- Type of supply (goods vs services)
- Place of supply rules
- Customer/residence status (resident vs non‑resident)
- Contract terms (for cross‑border or designated zone movements)
Common misclassifications include:
- Treating a supply as zero‑rated when it is standard‑rated (e.g. services related to goods located in the UAE provided to a non‑resident)
- Incorrectly accounting for expense reimbursements or intercompany service charges without invoices or appropriate terms
- Not separating local and export components where both exist
3. Designated Zone (DZ) to Mainland (ML) Transactions — Incoterms Drive VAT Outcome
Whether a supply between a designated zone and the mainland is zero‑rated, out‑of‑scope or standard‑rated depends on the incoterms and actual place of supply:
- EXW (Ex Works): If delivery and transfer of goods occurs in the designated zone and conditions are met, the transaction may be out of scope.
- DDP (Delivered Duty Paid): The supplier clears customs and delivers to the mainland premises. This typically constitutes a local supply and is subject to standard VAT (5%).
4. Legal Ownership VS Tax Obligation — Disclosed and Undisclosed Agency
Who owns the asset determines the primary VAT obligation. Two agency scenarios matter:
- Disclosed agency: The agent acts in the name of the owner. The law places VAT obligations on the owner — the owner must register (where required), report and account for VAT on supplies made in their name.
- Undisclosed agency: The agent acts in their own name and the end customer does not know who the owner is. In this case, the agent may be treated as the supplier and responsible for VAT.
Common audit finding: owners failed to register or declare supplies for years because they assumed the managing company or agent had taken care of VAT. FTA requires retrospective correction, registration and potentially large penalties.
5. Documentation: The Single Most Important Defense in a VAT Audit
FTA audits focus heavily on documentation. If you cannot prove a VAT treatment with the required documents, the FTA will treat the supply as standard‑rated and may apply penalties.
Key documentation items:
- Exit certificates and export/shipping documentation for zero‑rated exports
- Correctly formatted tax invoices that comply with FTA requirements
- Sales contracts, delivery notes, bills of lading, customs declarations and proof of payment
- Purchase documentation (purchase orders, GRNs, supplier invoices and payment evidence)
- Contracts and invoices between related parties, with appropriate supporting calculations for reimbursements and service charges
6. VAT Compliance in the Books: Accounting, Coding and Reconciliations
VAT is not separate from accounting it must be integrated into your financial statements and controls. Areas to check:
- Revenue recognition framework: ensure VAT treatment is aligned with IFRS classifications (IFRS 15 for customer contracts, IFRS 16 for leases, IFRS 9 for financial instruments where applicable)
- Reconcile VAT returns to general ledger and financial statements regularly — FTA audits request reconciliations
- Review intercompany invoicing, input VAT recovery eligibility and documentation supporting input VAT claims
- Maintain clear tax coding for each type of sale and purchase so VAT returns can be prepared reliably
7. Penalties, Retrospective Exposure and Voluntary Corrections
VAT non‑compliances can attract:
- Tax assessments (reclassification from zero‑rated to standard) with back taxes
- Late registration penalties and late filing penalties
- Administrative penalties for missing or incorrect documentation
Because VAT applies from 2018, small mistakes can create a large cumulative liability. Where errors are identified, consider voluntary disclosure and remedial adjustments early this can mitigate penalties compared with a discovered audit position.
8. Practical Checklist to Prepare for an FTA VAT Audit
- Run a VAT health check covering transitional transactions, sales and purchase classifications, and designated zone movements.
- Reconcile VAT returns with the general ledger and financial statements (prepare an audit information sheet).
- Validate incoterms on all DZ–ML transactions and correct VAT treatment where required.
- Map legal ownership of assets vs accounting records; confirm who should register and report VAT.
- Ensure export transactions have exit certificates and all required shipping documentation.
- Review invoice formats and supplier invoices before claiming input VAT.
- Document intercompany service agreements and charge mechanisms; ensure invoices are raised where needed.
- Maintain the FTA minimum audit file at the client premises and retain documents for the statutory period.
- Identify potential admin exceptions and make applications where appropriate.
Other Important Audit Focus Areas
- Revenue reconciliation and audit information sheets
- Eligibility of input VAT claims
- Inter‑company VAT treatment
- Wrong interpretation of date of supply rules and deemed supply provisions
- Review of commercial agreements for VAT implications
