The deadline for filing the 2018/19 self-assessment return online is 31 January 2020. Where a notice to file a return was issued after 31 October 2019, a later deadline of three months from the date of issue of the notice to file applies.
An earlier date of 30 December 2019 applies to taxpayers who have a liability of £3,000 or less which they would like to pay via an adjustment to their tax code.
A late filing penalty is charged if the return is filed late, even if it is only late by one day and regardless of whether any tax is due.
Speak to us to ensure that you understand what information you need to provide by when to ensure that the filing deadline is not missed.
Any tax that is unpaid for 2018/19 must be paid by 31 January 2020. The first payment on account for the 2019/20 tax year is due by the same date. Payments on account must be made where the previous year’s liability was £1,000 or more unless 80% of your tax liability is deducted at source, such as under PAYE. Each payment on account is 50% of the previous tax year’s tax and Class 4 National Insurance liability. The second payment on account for 2019/20 must be paid by 31 July 2020.
