Invoice INV-9901 (AED 35,000) entered on 3 Mar and again 11 Mar. Same invoice number, supplier TRN, and amount. Input VAT over-claimed by AED 1,750. FTA automatic audit trigger. Reverse immediately.
94
Residential resale coded as standard-rated Real Estate
Unit 4B Al Barsha Sale (AED 2.3M). Tagged 5% output VAT = AED 115,000. Should be EXEMPT — zero output VAT, no input claim on related costs. Net over-declaration: AED 115,000. Voluntary disclosure required.
89
Reverse charge omitted — 3 overseas suppliers All
Adobe CC, Slack, AWS invoices (total AED 12,400) not self-assessed. Under UAE VAT law, you must record both output VAT (payable) and input VAT (claimable) on imported services. Net effect is zero but omission is a penalty offence.
76
Wrong COA code — packaging expenses Retail
AED 28,400 of packaging costs posted to 5020-Office Supplies. Correct code: 4100-Cost of Goods Sold. Distorts gross margin, input VAT allocation, and CT deduction calculation.
71
TOMS margin not calculated — bulk booking Travel
Booking BK-4421 (AED 28,500 received, AED 22,300 paid to suppliers). VAT applied to full AED 28,500 = AED 1,357. Correct TOMS VAT on AED 6,200 margin = AED 295. Over-declared by AED 1,062.
68
Bank–ledger mismatch — DMCC entity Free Zone
4 supplier payments totalling AED 7,200 in bank statement not matched to AP ledger. Possibly unrecorded invoices or duplicate bank payments. Reconciliation required before VAT return.
52
Supplier TRN not FTA-verified — 3 invoices Retail
Gulf Packaging Co. TRN 100298765430001 returned inconclusive on last 2 FTA lookups. Input VAT of AED 3,420 at risk if TRN is invalid under 2026 due-diligence rules.
Anomaly detection methods
Duplicate fingerprinting
Fuzzy-matches invoice number + supplier TRN + amount + date. Catches re-entries, minor typos, and same-day duplicates.
VAT rate vs. supply type validator
Cross-references product/service description against UAE VAT treatment matrix. Flags mismatches (e.g. residential tagged as standard).
Statistical outlier detection
Flags invoices with unusual VAT% (e.g. 4.8% instead of 5%), round-number anomalies, and amounts 3σ outside supplier average.
Reverse charge scanner
Detects foreign supplier invoices with no UAE TRN and checks whether self-assessment entries exist in the same period.
COA code clustering
Claude AI reads invoice descriptions and suggests correct COA codes. Flags items posted to catch-all accounts that should be itemised.

QFZP red flags — active monitoring
⚠
Staff partially working outside free zone
2 employees log activity at mainland office 3 days/week. FTA may view core income-generating activities as happening outside the zone. Virtual office or outsourced ops are QFZP disqualifiers.
⚠
Mainland delivery — bill of entry not in DMCC name
Shipment to Dubai mainland client. Bill of entry filed in client's name, not DMCC entity. FTA treats this as excluded activity. All mainland BoE must be under the DMCC entity's name.
✓
Qualifying income ratio — de minimis met
Non-qualifying income is 3.2% of total revenue — well below the 5% de minimis threshold. QFZP status safe on income test.
✓

Per SME
🍽️ Food & BeverageHigh volume
UAE has 20,000+ F&B outlets. Key pain: zero-rated takeaway vs 5% dine-in confusion, Dubai Municipality inspections, and multi-branch VAT consolidation.
What TaxOS adds:
↳ Dine-in vs takeaway auto-split per transaction
↳ POS system integration (Foodics, Revel, Square)
↳ Multi-branch VAT consolidation
↳ Staff meal deduction blocker (input VAT blocked)
🏗️ ConstructionComplex
Retention payments, progress billing, subcontractor invoicing, and time-of-supply rules at contract milestones are widely mishandled.
What TaxOS adds:
↳ Retention VAT: triggered on release, not invoice
↳ Subcontractor TRN verification pipeline
↳ Progress billing VAT calculation by milestone
↳ Zero-rating check for exported construction
🏥 Healthcare & ClinicsGrowing
DHA/MOH-licensed medical services are zero-rated. Non-licensed cosmetic procedures are 5%. The line is frequently crossed incorrectly, especially in aesthetics clinics.
What TaxOS adds:
↳ Medical vs cosmetic auto-classifier (AI)
↳ DHA licence number verification per invoice
↳ Insurance vs self-pay VAT split
↳ Zero-rating evidence pack for FTA audit
🎓 EducationZero-rated
Approved educational services are zero-rated — but ancillary services (canteen, transport, uniform) are 5%. Many schools lump everything as zero-rated and claim excess input VAT.
Banks, insurance, and currency exchange are exempt — but advisory fees, fintech SaaS, and ATM services are 5%. Partial exemption calculations are almost always wrong.
What TaxOS adds:
↳ Exempt vs taxable income separator
↳ Partial exemption method (standard / special)
↳ Interest income vs fee income split
↳ CBUAE-regulated entity compliance flags
📦 E-commerce & LogisticsFast growing
UAE e-commerce sellers on Amazon, Noon, and Shopify often confuse the zero-rating rules for exports, miss reverse charge on overseas platform fees, and misclassify DZ warehouse stock.
What TaxOS adds:
↳ Marketplace fee reverse charge automation
↳ Export evidence pack (airway bill + customs)
↳ DZ stock vs mainland stock VAT split
↳ Amazon/Noon API invoice import
