Why this matters for Oman trades
The Oman Tax Authority runs 5% VAT and the phased Fawtara e-invoicing mandate (large taxpayers August 2026; all VAT-registered businesses August 2027); OSE accreditation is required for engineer work permits (since August 2025); the Authority for Projects, Tenders & Local Content runs contractor classification and procurement; the Ministry of Labour enforces Omanisation; municipalities issue building permits; MoHUP owns the new Oman Building Code (phasing in to 2030); and the CDAA is the national fire-safety authority.
Oman construction software selection is defined by an imminent e-invoicing mandate — the Oman Tax Authority’s Peppol-based “Fawtara” system reaches large taxpayers in August 2026 and all VAT-registered businesses by August 2027 — alongside 5% VAT, OSE engineer accreditation (now tied to work permits), contractor classification via the Authority for Projects, Tenders & Local Content, Omanisation quotas, municipal building permits, the new Oman Building Code, and CDAA fire safety.
