The annual capital gains exemption (currently £12,300) may cover most of the capital gains that you make on your share portfolio. However that exemption will be cut to £6,000 on 6 April 2023 and £3,000 in April 2024.

Companies can currently claim super-deduction allowances set at 130% of the cost of new plant and machinery or 50% of the purchase cost of certain fixtures and fittings for buildings. These super-deductions will expire on 31 March 2023.

When an individual dies everything they own is valued to calculate the inheritance tax (IHT) due on their estate. These assets include the deceased's main home and any let properties they may own.

In the March 2021 Budget the Chancellor announced a super-deduction scheme that provides a 130% deduction for the cost of new plant or equipment if it is purchased by a company before 1.4.23. Expenditure on other new assets such as fixtures and integral features in buildings can also qualify for a 50% first year deduction if purchased before 1.4.23.
