Interest

Do I calculate interest and fees myself, or who does?

Interest and fees are determined by the relevant Inland Revenue Office or Taxpayer Service Office. Notice of them can be sent attached to the jeopardy or amended assessment order issued under section 102 of the Income Tax Act.

How is interest calculated?

Interest is charged at the standard rate of 15% a year on unpaid tax for each month and part of a month from the due date until payment.

  • Instalment tax: from each instalment's due date to the end of Ashwin of the following fiscal year.
  • Tax due with the return: from the end of Ashwin after the income year until paid. An extension of time to file the return does not stop interest running.
  • Where the taxpayer under-declared income and the office raises additional liability: interest runs as short-paid instalments up to the end of Ashwin after the fiscal year, and as late payment from 1 Kartik.

What is the interest rate?

15% a year. This is called the standard interest rate.

Late payment of which taxes attracts interest?

Tax demanded by an Inland Revenue Office notice, instalment tax, withholding tax, and tax due with the return, if not paid on time.

Fees

Are fees charged at a fixed rate like interest, or at the tax officer's discretion?

Fees are charged at prescribed rates, like interest, and the tax officer has no discretion over them. However, a person who fails to comply with the Act or Rules, where no specific interest or fee provision applies, can be charged a penalty-type fee of NPR 5,000 to NPR 25,000 depending on the nature of the non-compliance.

Can both interest and a fee be charged to the same person at the same time?

Yes

Interest and fees serve different purposes, so both can be charged to the same taxpayer on the same return for the same income year. A fee is charged for failing to comply with the law; interest is charged as financial compensation.

What is a fee, and how is it different from interest?

A fee is a financial penalty imposed by the tax administration on a person who fails to file a return, files a false return, knowingly helps prepare a misleading or false return, or otherwise fails to comply with income tax law. Interest is financial compensation for paying tax late. It is an economic disincentive that protects revenue collection from taxpayers holding back tax to use the money elsewhere, and compensates the Government when that happens.

How are fees assessed, and by whom?

Fees are calculated either as a percentage of the tax underpaid or as a fixed prescribed amount. In a self-assessment the taxpayer calculates the fee; in an amended assessment the tax officer does.

How are fees calculated?

  • Failing to file an instalment or estimated tax statement: NPR 5,000 per statement or 0.01% of the assessable income shown in the return, whichever is higher.
  • Failing to file a presumptive tax statement: NPR 100 per month.
  • Any other person failing to file a return: 0.1% a year of assessable income (calculated without deductions, that is on turnover, and including amounts that must be included) or NPR 100 per month, whichever is higher.
  • Failing to keep required documents: 0.1% of turnover or NPR 1,000 a year, whichever is higher.
  • Filing a false or misleading statement knowingly or recklessly: 100% of the tax underpaid; where the error was a genuine mistake: 50% of the tax underpaid.
  • An accomplice: 100% of the tax underpaid by the person helped. Any other breach of the Act or Rules: NPR 5,000 to NPR 25,000.
  • A person required to withhold tax who does not file the statement within 25 days of the end of each month: 2.5% a year of the amount required to be withheld.

In which situations are fees charged?

For failing to keep documents, failing to file a statement or return, filing a false or misleading statement, and knowingly or recklessly helping or advising a person to commit an offence. A fee can also be charged to anyone who fails to comply with any other provision of the Income Tax Act or Rules.

What happens if my self-assessment contains an error? Do I pay a fee even if the error was not deliberate?

An error in a self-assessment return attracts a fee of 50% to 100% of the tax underpaid as a result. If the error was a genuine mistake, not deliberate, negligent or due to a false statement, the fee is 50%. If the return was false or misleading because of deliberate action or negligence, the fee is 100%.

Penalties and prosecution

How are interest, fees, penalties and fines recovered?

Interest and fees are assessed by the relevant Inland Revenue Office or Taxpayer Service Office along with any jeopardy or amended assessment, attached to the notice given to the taxpayer under section 102, and recovered in the same way as tax. For penalties and fines, the Government files a case in the District Court as plaintiff, and the court's decision is enforced.

Who can face penalties and fines?

Anyone who commits an offence under Chapter 23 of the Income Tax Act. That includes a person required to pay tax or file a return, an accomplice who certifies false financial or tax accounts, gives wrong advice or helps prepare a misleading return (for example an auditor or legal adviser), and an authorised official or a person impersonating one. They may face imprisonment and fines.

What do interest, fees and penalties apply to?

Interest applies to tax not paid on time. Fees apply to failing to file returns or instalment estimates on time, failing to keep documents, failing to comply with any provision of the Income Tax Act or Rules, filing false or misleading statements, and knowingly or recklessly helping someone commit a tax offence. Under a court decision, a cash fine, imprisonment or both can be imposed for failing to pay tax, giving false or misleading statements, obstructing or improperly influencing the tax administration, acting as an accomplice, offences by authorised or unauthorised persons, and failing to comply with the Act.
