Quarterly set-aside (savings estimate)
£16,847.74
Set aside £16,847.74 per quarter as a savings estimate (a quarter of the year's income tax and Class 4 NI). Self Assessment is paid on 31 January and 31 July, usually as two payments on account of half the previous year's bill. First year: there are no payments on account yet, so your first 31 January bill is the whole year-one bill plus the first payment on account for year two — up to 150% of a year's tax on one date. Save extra before your first January. How quarterly tax works.
