HMRC must accept certain tax returns for a certain number of years and any money paid by the deadline. These deadlines are centered on the tax year beginning in April and ending on April 5.

In addition, interest on the penalty will be added to the cost.

This can be further increased for the partnership because if the tax return is delayed, a penalty will be levied for all the partners.

Tax returns, like many elements of financial life at the moment, have been affected by the coronavirus in recent months.

If a person, known as an account payer, pays their bills in advance, there is usually a July 31 second deadline.

According to the government, a reasonable excuse is an issue that prevents a person from fulfilling their tax liability which they took due care to show properly, which may include the following examples:

• A partner or other close relative dies shortly before the tax return is due
• The man had unexpected hospital stays that prevented him from handling tax matters
• They had a serious or fatal illness
• Their computer or software failed just before or at the time they prepared the return online
• Service problems with HM Revenue and Customs (HMRC) online services
• Fire, flood or theft prevent them from completing their tax return
• Postage delays that they cannot predict
• They delay related to a disability
