Company details
Common addbacks
These are expenses in your accounts that are not allowable for corporation tax and need to be added back to arrive at taxable profit.
This calculator provides estimates based on the current main rate (25%) and small profits rate (19%)
with marginal relief. It does not cover R&D reliefs, patent box, group relief, or complex loss computations.
Capital allowances should be calculated separately and entered as a deduction above.
Always seek professional advice for your specific circumstances.
