Corporation tax is 25% for profits over £50,000

Corporation tax is 25% for profits over £50,000, with marginal relief for profits between £50,000 and £250,000.
Does Tiny Tax calculate the tax charge correctly for profits over £50,000.
Or, do I need to calculate and enter the correct tax charge.

Normally CT600 forms should calculate the correct tax charge, including marginal relief.

TinyTax does calculate marginal relief for you. If you search for a company from https://tinytax.co.uk you will land on our main data entry form which will let you explore the tax calculation before signing up if you'd like to review first.
