The Self Assessment deadline is on 31st January 2021. SA filers can complete their tax returns online ahead of the deadline at a time that suits them.
Every year, HMRC sees thousands of customers using the festive period to get their documents in order and complete the task.
On Christmas Day, the peak time for completing tax returns was 14:00 to 14:59, with more than 200 customers pressing send on their online form.
Once Self Assessment tax payers have completed their 2019 to 2020 tax return, and know how much tax is owed, they can set up their own payment plan to help spread the cost of their tax liabilities, up to the value of £30,000. They can use the self-serve Time to Pay facility to set up monthly direct debits online. Interest will be applied to any outstanding balance from 1st February 2021.
