What is a HMRC self-assessment tax return?

One of the most frequently asked questions people have at certain times of the year is “What is a HMRC self-assessment tax return?” which is hardly surprising because tax is complicated.

A self-assessment tax return is a way of telling HMRC how much tax you are required to pay based on your income and any taxable gains you have during the tax year, which runs from April 6th until April 5th the following year.

For example, if you are a self-employed photographer and earn income through freelancing or running a small business, you would need to complete a self-assessment tax return to declare your earnings and calculate the amount of tax you owe.

Who needs to file a HMRC self-assessment tax return?

The following is a list of people and/or situations where you may need to file a HMRC self-assessment tax return:

  • You are a self-employed person who earns more than £1000 from things such as working for Deliveroo or from a side hustle.
  • You earned more than £10,000 from savings interest. For example, if you have a large amount of money in a bank account and each year that money earns interest of £10,000+, then you need to file a self-assessment tax return.
  • You have a property that you rent out, and the rental income is over £1000 during the tax year.
  • If you love the thrill of trading stocks on the stock market and you make more than £3000 in profits, you have to file a HMRC self-assessment tax return. This also applies to other profits from investments, such as property.
  • You are earning foreign income, for example, wages if you work abroad or rental income from overseas property.
  • You received more than £10,000 in dividends, which is a sum of money you might get if you own shares in a limited company.

If you don’t think you apply to this list above but still think you may need to file a HMRC self-assessment tax return, you might need to speak to an accountant for help.

It is also worth pointing out that there may be other scenarios where someone may have to prepare and file a HMRC self-assessment tax return, for example, if they paid too much income tax. Please see the details below:

  • Sometimes you may be required to file a tax return if you made donations to charity.
  • Your work expenses exceeded £1000.00.
  • You made investments in SEIS- or EIS-eligible startups or VCT funds.
  • Sometimes people have untaxed income that cannot be paid through PAYE, so they will need to prepare a HMRC self-assessment tax return.

What happens if I don’t file a HMRC self-assessment tax return?

If you have multiple jobs, a family, and other commitments, life can be very hectic, and as a result, you let things slip. If this describes your situation, you are probably wondering: What happens if I don’t file a HMRC self-assessment tax return?

Below is a breakdown of what to do if you don’t file a self-assessment tax return on time, as well as potential penalties and charges:

Fines for filing a late self-assessment tax return

A day late: £100 fine

If you realise you haven’t filed your tax return and it is only a day late, you may automatically be charged a £100.00 fine.

Three months late: maximum £1000 fine

After three months, if you still haven’t filed your self-assessment tax return, the fines start to increase significantly. After three months, you will be charged £10 per day, which is capped at 90 days plus the £100 fine mentioned above, to a maximum of £1000.

Six months late

Filling a tax return more than six months late will incur all the previous fines I discussed above, plus either a £300 fine or 5% of the tax due (whichever is greater).

Twelve months late

If your tax return is still not filed after twelve months, there is an additional £300 fine plus 5% of the tax due. In serious cases, some people have been fined 100% of the total tax due.

Charges for not paying your tax bill on time

Should you have to pay tax after completing your self-assessment tax return, you must pay the tax by 31st of January the following year. If you don’t pay the tax on time,as well as being charged the previously mentioned fees, you will also be charged 7.75% interest from the date the tax payment was due.

Additionally, you may also be charged the following penalties for not paying the outstanding tax on time:

  • 30 days plus You will receive a charge equal to 5% of the tax outstanding.
  • 6 months plus a further 5% of the tax outstanding
  • 12 months + an additional 5% charge

What should I do if I haven’t completed my self-assessment tax return?

  1. If you realise that you haven’t completed your self-assessment tax return, contact HMRC immediately and explain the situation. If your reason for not filing is reasonable, they may reduce some of the fees or charges that get applied.
  2. Complete the tax return as soon as possible, even if you are not in a position to pay any tax that might be due, since you may be able to set up a payment plan to pay it off gradually.

If this all feels a little overwhelming, it may help to get advice by speaking to an accountant about your situation.
