HMRC scraps late filing penalty for those who file online by 28 February Taxpayers will not receive a penalty for their late online tax return if they file by 28 February, HMRC’s Chief Executive Jim Harra has announced. More than 8.9m customers have already filed their tax return. HMRC is encouraging anyone who has not yet filed their tax return to do so by 31 January, if possible. Anyone who cannot file their return by the 31 January deadline will not receive a late filing penalty if they file online by 28 February. The move comes after accountancy and tax professional bodies argued that advisers and taxpayers would struggle to meet the deadline this year because of the impact of COVID-19.
