Late payment penalties for Self Assessment waived until 1 April HMRC has announced that Self Assessment taxpayers will not be charged a 5% late payment penalty if they pay their tax or set up a payment plan by 1 April. The payment deadline for Self Assessment is 31 January and interest is charged from 1 February on any amounts outstanding. Normally, a 5% late payment penalty is also charged on any unpaid tax that is still outstanding on 3 March. But this year, because of the impact of the coronavirus (COVID-19) pandemic, HMRC is giving taxpayers more time to pay or set up a payment plan. Taxpayers can pay their tax bill or set up a monthly payment plan online and are required to do this by midnight on 1 April to prevent being charged a late payment penalty. The online Time to Pay facility allows taxpayers to spread the cost of their Self Assessment tax bill into monthly instalments until January 2022. Jim Harra, HMRC's Chief Executive, said: 'Anyone worried about paying their tax can set up a payment plan to spread the cost into monthly instalments. Support is available at GOV.UK to help anyone struggling to meet their obligations.' Internet link: HMRC press release
