What Article 202 actually covers
Article 202, as amended by Decision 456/2022, lists four violations carrying the same OMR 500 to OMR 5,000 range.
| Violation | Reference |
|---|---|
| Failure to submit tax returns by the legally prescribed dates | Article 202 |
| Failure to display the Registration Certificate in a visible place | Article 123 |
| Failure by a de-registered taxable person to keep accounting records, books and documents | Article 142 |
| Failure to issue a tax invoice, or an electronic tax invoice, meeting the requirements set out in the Regulations and by the Tax Authority, and within the specified period | Added by Decision 456/2022 |
The fourth item is the one that concerns invoicing, and it is worth knowing where it came from. In the original 2021 text of the Regulations, Article 202 covered only the first three and said nothing about invoices. The invoice violation exists solely because Decision 456/2022 added it. Any citation of Article 202 for an invoice penalty that omits the amendment is incomplete.
The same decision amended Article 1 to define an Electronic Tax Invoice as a tax invoice generated in a structured format by electronic means. That definition, rather than Fawtara, is what the invoice provision currently rests on.
What triggers it
Three things, and only one of them is the obvious one.
- Not issuing an invoice at all. The clearest case, and the least common among businesses that are trying to comply.
- Issuing an invoice that is missing required content. Article 144 sets the mandatory fields. An invoice missing any of them is not a compliant tax invoice, however it looks. The two omissions we see most often are the supply date, which is a separate field from the issue date, and a discount shown as a percentage rather than as a value.
- Issuing outside the time limit. Article 143, as amended by Decision 456/2022, requires the invoice within 15 days of making the supply, making a deemed supply, or receiving consideration in full or in part before the date of supply. The third trigger is the one most often missed. An advance payment starts the clock even though nothing has been delivered.
The full Article 144 checklist
This is the complete mandatory field set. Sub-item numbers are given so you can check an invoice against the Regulations directly.
| Field | Article |
|---|---|
| The title Tax Invoice, using that exact term | 144(1) |
| Issue date | 144(2) |
| Supply date, as a field separate from the issue date | 144(2) |
| Payment date, where payment was made before the invoice was issued | 144(2) |
| Sequential invoice number | 144(3) |
| Supplier full legal name, address and VAT identification number | 144(4) |
| Customer full name, address, and VAT identification number where they have one, or its equivalent in their country of residence if non-resident | 144(5) |
| Description of goods or services | 144(6) |
| Quantity of goods | 144(7) |
| Advance payment date, where any advance was received | 144(8) |
| Total consideration excluding tax | 144(9) |
| Tax rate applied | 144(10) |
| Discounts, reductions or state subsidies not already deducted | 144(11) |
| Taxable value | 144(12) |
| Tax due, in Omani rials | 144(13) |
Two requirements sit alongside the list and are missed more often than any single field.
- The invoice must be in Arabic. Article 144 states that issuance shall be in Arabic. English is permitted provided an Arabic translation can be furnished at the Tax Authority’s request. An English-only invoice leaves that obligation with you.
- A discount must show its value. Under Article 35, a discount is excluded from the taxable value only where the discount value is written on the invoice and the supplier has a clear discount policy. A line reading "10% discount" with no value does not satisfy this, and the effect is on the tax you owe, not only on the paperwork.
The mistake that costs more than the penalty
Article 211 receives almost no attention and is more expensive than the penalty provision for most contractors.
Where a contract or agreement regulating a supply contains no provision relating to tax, the consideration is deemed to be inclusive of the tax. Tax is added on top only where the document states explicitly that amounts exclude tax.
In practice: a contractor quotes OMR 10,000 for a job, the quote says nothing about VAT, and the customer issues a purchase order for OMR 10,000. That contract is legally VAT-inclusive. The contractor owes OMR 476.190 in output tax out of the 10,000 received, calculated as consideration multiplied by the rate and divided by 105 under Article 41.
There is no penalty here. Nothing has been done wrong. The money simply comes out of the margin, on every job where the document was silent, and it is roughly 4.76% of the contract value each time.
The fix takes one line. State on every quote and invoice whether prices include or exclude tax. There is no third state, and silence is not neutral.
How to correct a mistake
Article 155 requires an adjustment document conforming to Article 144, identifying the original invoice or invoices and the tax value being adjusted. In practice this is a credit note for a downward adjustment and a debit note for an upward one.
There is no void mechanism in the Regulations. Deleting an issued invoice and replacing it is not a correction path, and the distinction stops being administrative once invoices are reported as they are issued.
Article 48 additionally requires that a credit note reference the original tax invoice number where tax due is adjusted downward following cancellation, rejection or a discount.
What changes under Fawtara
The penalty provision does not depend on Fawtara and has applied since October 2022. What Fawtara changes is verifiability.
Today, an invoice missing a required field is non-compliant but is unlikely to be noticed unless the business is examined. From your Fawtara phase, invoices are structured, validated and reported as they are issued, so a missing or malformed field is caught by the system rather than found later.
That is the practical case for fixing invoice content now rather than in 2027. The requirement is identical either way; only the probability of it being observed changes.
Records
Records must be kept for ten years generally, and fifteen years for records relating to real estate. They may be kept in any language, provided they can be produced in Arabic if the Tax Authority requests it.
Common questions
Every Yusrin invoice carries the fields Article 144 requires, states whether prices include or exclude tax, and issues a credit note rather than a deletion when something needs correcting.
