Understanding Penalties for Non-Compliance under Oman Tax Law

Oman enforces tax compliance with a structured penalty system under the Income Tax Law.

Here’s what you need to know:

  • Late Filing: OMR 20 per day, up to a maximum of OMR 2,000.
  • Failure to Pay: Interest at 1% per month on unpaid taxes, starting from the due date.
  • Failure to Withhold Tax: Leads to a fine equal to the tax amount not withheld, in addition to interest.
  • Failure to Submit Final Accounts: May result in rejection of tax return or tax being estimated by the authority, often less favorable to the taxpayer.
  • Obstruction or Misrepresentation: Can lead to criminal penalties, including imprisonment in serious fraud cases.

Taxpayers have the right to appeal, but timelines are strict. The Tax Grievance Committee or judicial courts may review disputes if timely objections are filed.

The law is clear: compliance is not optional. Proactive management and professional advice can protect your business.

Next, we’ll look at the role of the Secretariat General for Taxation (SGT)—the key authority in Oman’s tax landscape.
