Remember there is a 5% unpaid tax surcharge if your personal tax remains unpaid at the end of February, July and the following January. There is also a £10 daily penalty if your personal tax return is not filed by 30th April of the following year up to a maximum £900. There is then an additional 5% or £300 (whichever the greater) charged if your tax return is still not filed by the end of July and again by the end of the following January.

Remember to avoid an HMRC penalty you must have filed and paid your personal 2025 tax return and tax liability by 31st January 2026. You should also pay, to avoid extra interest, the first payment on account towards your 2026 tax liability.
