Around 4,000 UK customers of financial services provider Wise have been told that tax statements issued between 2021 and 2025 contained incorrect figures. The errors could have resulted in taxpayers paying too much or too little income tax and capital gains tax (CGT). What should affected customers check?

According to reports published on 8 October, the problem arose from software supplied by a third-party provider used in connection with Wise’s investment products. Incorrect calculations of investment income and capital gains were included in statements that customers could have relied on when completing their Self-Assessment tax returns. Wise says it identified the errors through its internal checks, has corrected the underlying software problem and has issued revised statements to affected customers. However, receiving an incorrect statement does not necessarily mean that a taxpayer paid the wrong amount of tax.

The company is now discussing a possible bulk settlement with HMRC to cover tax shortfalls arising from the errors. It has also said that customers who overpaid tax will be compensated. The proposed settlement has not yet been finalised, so affected customers should not assume that any outstanding tax liabilities have already been resolved. Anyone receiving a corrected statement should compare it with the figures included in their original tax returns. Where the amounts differ, the next step is to establish whether the error actually changed the tax payable. Customers should also retain the original and corrected statements, together with any correspondence from Wise explaining the proposed arrangements.
