Capital allowances

The tax version of depreciation. From 2026 it is straight-line by class, the initial allowance is gone, and an asset you did not pay VAT or duty on cannot be claimed at all.

Every figure on this page is read from the same configuration the calculators use — none of it is typed into the page. If a number here is wrong, the calculators are wrong too, and a changelog entry will record the correction.

The three classes

Your accounting depreciation is ignored for tax. These rates replace it.

The annual rates did not move. What went is the initial allowance — a large first-year deduction claimed alongside the annual one. Losing it does not reduce the total relief you get over an asset’s life, but it pushes that relief later, and later relief is worth less.

The rules around them

From 2026 capital allowances are straight-line by class with no initial allowance. An asset on which VAT or import duty was not paid is not claimable at all. 1% of cost is retained notionally until disposal.

Under the old regime an initial allowance was claimed in year one alongside the annual allowance. The 2026 regime drops the initial allowance in favour of straight-line only.

Tax written-down value

An asset’s tax written-down value is its cost less every allowance claimed on it so far. It is the running balance that drives next year’s claim and decides what happens on disposal: sell above TWDV and the excess relief is clawed back as a balancing charge; sell below it and you get a balancing allowance.

Because 1% of cost is retained notionally until disposal, TWDV does not reach zero while the asset is still on your books.

Tools that use these rates

Note the interaction worth watching: capital allowances reduce total profits and so reduce companies income tax, but they do not reduce assessable profit, which is what the 4% development levy is charged on.

A rate reference is not tax advice, and a rate on its own does not tell you your position. Read the disclaimer, and confirm anything load-bearing against the gazette before acting on it.
