What Capital Gains Tax Means

Regular maintenance does not count as an improvement. After these deductions, the remaining amount becomes your taxable gain.

Capital Gains Tax Rates

Tax rates depend on your income band. If you fall under the basic rate, you pay eighteen percent. If your income puts you in the higher band, the rate rises to twenty eight percent. Your tax rate applies only to the gain, not to your full income.

Allowances and Reliefs
