Business Asset Disposal Relief

Work out your tax

How you work out your tax depends on whether all your gains are eligible for Business Asset Disposal Relief.

Work out the gain for all qualifying assets.
Add together the gains (and deduct qualifying losses) to work out the total taxable gain that’s eligible for Business Asset Disposal Relief.
Deduct your tax-free allowance.
You’ll pay 10% tax on what’s left.

How much tax you pay on your other gains depends on what Income Tax rate you pay.

Work out your total taxable gain.
Use your basic rate band first against any gains eligible for Business Asset Disposal Relief. You’ll pay 10% tax on these.
Use any remaining basic rate band against your other gains. You’ll pay 18% on gains made on residential property and 10% on gains from all other chargeable assets.
For gains above the basic rate band you’ll pay 24% on gains made on residential property and 20% on gains from all other chargeable assets.
You can use your tax-free allowance against the gains that would be charged at the highest rates (for example where you would pay 24% tax).
