Do small businesses in Oman need e-invoicing?

OMR 38,500 or OMR 5 million: which number is yours?

Two numbers get confused, and they do different jobs:

• OMR 38,500: the mandatory VAT registration threshold as currently reported, with voluntary registration open from OMR 19,250. It decides whether you are VAT-registered at all. These figures are set by decision of the Tax Authority Chairman with Cabinet approval, so they can change.
• OMR 5 million: a line that separates two dates only, 1 April 2027 and 1 October 2027, under Article 3 of the Decision. It has nothing to do with VAT registration.

So the Decision sets no minimum size for e-invoicing. Once you are VAT-registered you are in scope, however small your supplies. Article 55 of the VAT Law requires registration when your supplies for any month plus the eleven months before it exceed the registration threshold, or when you expect them to exceed it over the next twelve months. If you are near the line, ask your accountant now: registering brings you into e-invoicing.

What actually changes for a small business

• The invoice: issued electronically as XML in the PINT OM standard, with a unique number, within 15 days of the event that requires it (Article 143). The Authority's FAQ states that a PDF invoice is not an e-invoice.
• The provider: an accredited service provider validates your invoice and reports its data to the Tax Authority, and you choose it. You do not have to become a provider yourself. See accredited service providers.
• Your software: the FAQ says your current system can be retained under your arrangement with the provider, as long as it produces the invoice in the required format.
• Consumer invoices: submitted within 24 hours, with a QR code on the human-readable invoice (not in the e-invoice file). Paper stays allowed for consumer invoices, in addition to the electronic format.
• Records: storing invoices is the taxpayer's responsibility, not the Authority's or the provider's, for ten years after the end of the tax year in which the return was filed (VAT Law Article 70).
• Responsibility: the FAQ says responsibility for a compliant invoice stays with the taxpayer, while the Authority monitors providers' performance.

Is there an exemption or a simplified regime for small businesses?

We found neither a size-based exemption nor a simplified regime in the Decision or the FAQ. What exists is an individual exemption: Article 143 bis 2 lets the Tax Authority Chairman excuse a taxable person from issuing electronic tax invoices for a period the Authority sets, on a written request with supporting documents and reasons the Authority accepts, on condition that you file your VAT returns and pay the tax on time. It is not an automatic right.

Is there a free government invoicing tool for small businesses? We found no official source describing one. That is an absence of evidence, not a confirmed no. If you think your case is special, ask the Tax Authority directly.
