Marginal relief
From ACT Wiki
- UK Corporation Tax. Tax relief for companies or other organisations whose taxable profits are in between the upper limit for the (reduced) small companies' rate and the lower limit for the (full) main rate of Corporation Tax. Marginal relief smooths the transition from the reduced rate of corporation tax to the full rate.
- UK Capital Gains Tax (CGT). Tax relief in relation to disposals of assets for proceeds which are marginally above the threshold for total exemption from CGT, reducing the amount of tax would otherwise be payable.
