UK Non-Resident Company Tax Rates

In April 2023, the main Corporation Tax rate was increased from 19% to 25%. A small profits rate (SPR) of 19% for profits below £50,000 and marginal relief (MR) was introduced for profits between £50,000 and £250,000 which can be used by certain company types.

Non-resident companies without a permanent establishment within the UK are not eligible to use the SPR or apply MR and must use the main tax rate when calculating the tax on any profits.

The few exceptions can be found by searching GOV.UK and are outlined in:
