Self-assessment tax payers have just three days left to avoid £100 late fine

SELF-assessment tax payers have until midnight on Sunday to file their return and avoid a £100 fine.

The deadline to submit tax returns for 2019/20 was January 31 but HMRC waived the late payment charge so long as they are submitted by February 28.

Delaying the fines was aimed at helping those who were struggling to meet the deadline due to the impact of the third national lockdown.

But tax payers will still have been charged interest worth 2.6% of the outstanding amount every day until the payment is made from February 1.

According to HMRC, nearly two million people missed the end of January deadline this year.

Tax returns will need to be filed online now though as those returned by post or via the bank will still incur the fee.

How do I fill out the tax return?

Here's what you need to know:

BEFORE you can complete and submit your tax return, you'll need to have a unique taxpayer reference (UTR) and activation code from HMRC.

This can take a while to receive, so if it's the first time you're completing self-assessment, make sure you register online as soon as possible.

If you've already signed up for self-assessment, you can find your UTR on relevant letters and emails from HMRC.

HMRC accepts your payment on the date you make it, not the date it reaches its account - including on weekends.

If you need to change your tax return after you've filed it, you can do so within 12 months of the original deadline or you can write to HMRC for any changes after that.

Filling in your tax return can seem daunting, but with our step-by-step guide you'll have it sorted in no time.

Late payments submitted after February 28 deadline will be fined as normal.

HMRC has already said it will accept Covid disruption as a reasonable excuse for people missing the deadline, although they'll still be hit with a fine.

Customers will then have to appeal the penalty that's been issued by proving they have been negatively impacted by coronavirus, which has caused a delay in making the deadline.

How much could I be fined if I hand it in late?

Normally, a 5% late payment penalty is charged on any unpaid tax that is still outstanding after 30 days.

After this, you get charged another 5% of what you owe at six months, and another 5% again at 12 months.

But because of the coronavirus pandemic, HMRC has agreed to waive the 5% payment penalty charged on unpaid tax that is still outstanding on 3 March 2021, as long as you pay or set up payment plan by 11.59pm on April 1.

A 5% late payment penalty fee will still be charged after 1 April.

At six months, you'll be fined 5% of the tax you owe or £300, whichever is greater.

You'll be charged this again at 12 months, or you could be asked to pay 100% of what you owe in full.

You can calculate how much your fine will be on the .

What if I need more time?

HMRC has a which breaks down what you owe into monthly instalments to make it more affordable.

Due to the financial impact of the pandemic, it’s been made available to more people who are struggling to pay their tax bills this year.

HMRC says more than 97,000 people have already signed up for its Time to Pay arrangement.

To be eligible for the arrangement you must:

  • You owe £30,000 or less
  • You do not have any other payment plans or debts with HMRC
  • Your tax returns are up to date
  • It’s less than 60 days after the payment deadline (January 31st)

You can choose how much to pay straight away and how much you want to pay each month. You’ll have to pay interest.

You can choosing how much you want to pay upfront and how much you want to pay in instalments.

However, you will still be charged 2.6% interest on any tax that’s outstanding after 31 January.
