What OTA compliance means for you

Oman launched VAT in 2021 and is now phasing in mandatory e-invoicing. Businex360 handles both.

Every Oman business with taxable supplies above OMR 38,500 / year must register for VAT with the Oman Tax Authority and file quarterly. Invoices must show TRN, 3-decimal OMR amounts, VAT breakdown per line, and be issued within 15 days. Businex360 handles all of it automatically — including the 3-decimal baiza rounding rules that break most cloud POS systems designed for 2-decimal currencies.

E-invoicing: OTA has announced a phased Kingdom-wide rollout. Government-to-business (B2G) transactions first, followed by B2B by 2027 and B2C thereafter. Businex360's compliance layer generates the required UBL XML and hands off to accredited service providers — no upgrade fee when your wave arrives.

Built for Oman

Compliance, POS and accounting — localized for the Sultanate.

Every feature below ships out of the box. No middleware. No connector fees.

5% VAT with correct baiza rounding

Every amount uses banker's rounding to 3 decimals (baiza) — the OTA default — so quarterly returns tie back to the baiza on the invoice.

E-invoicing UBL generation

FAQ · Sultanate of Oman

Common questions from Oman finance teams.

What is the current VAT rate in Oman?

5% standard rate since April 2021. Zero-rated categories include basic foodstuffs, medicines, education, healthcare and international transport. Exempt supplies include financial services and residential rent.

When do I need to register for VAT with OTA?

Mandatory registration once annual taxable turnover exceeds OMR 38,500. Voluntary registration is available from OMR 19,250. Businex360 tracks your rolling 12-month turnover automatically and warns before the threshold hits.

Does Businex360 handle 3-decimal OMR (baiza) rounding?

Yes. Every amount is stored and rounded to 3 decimals (baiza) using banker's rounding, per OTA guidance. Returns and reconciliations tie back to the baiza on the receipt — no half-baiza drift.

Is e-invoicing mandatory in Oman yet?

Rolling out phased. OTA is starting with B2G in 2026 (government contractors), moving to B2B by 2027, and B2C thereafter. Businex360 already generates the required UBL XML — when your wave activates, you toggle it on with no re-onboarding.

Does Businex360 export to the OTA VAT return format?

Yes. Quarterly VAT returns export in the OTA-required layout with standard-rated, zero-rated, exempt and import VAT auto-classified per invoice. What you submit through the OTA portal matches what your quarterly reconciliation shows.
