Self assessment penalties

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.
