What happens to my tax position when I sell equipment I claimed allowances on?

When you sell an asset on which capital allowances were claimed, you normally bring a disposal value into the capital allowance calculation. For a straightforward sale, this is usually the sale proceeds, subject to rules that generally cap the value at the original cost. Gifts, private transfers and transactions with connected parties can require a different value. The result depends on whether the asset sits in a general pool or has separate treatment, and on any remaining pool balance. A sale does not always mean every pound of proceeds is immediately taxable. However, equipment fully relieved through AIA can produce a balancing charge where the relevant calculation requires one.

Your accounts remove the asset’s original cost and accumulated depreciation and show any profit or loss against its accounting value. The tax return then makes the appropriate adjustments and deals with capital allowances separately. That is why the accounting profit on a sale may differ from the taxable amount. If the business is VAT registered, also check whether VAT must be charged on the disposal; the original allowance claim does not decide that question. Keep the invoice, sale date and original purchase details together. CASS can reconcile the asset register to the allowance pools and help you understand the tax and cash effect before you agree a sale or trade-in.
