Overview
- HMRC issued a renewed social‑media reminder on March 19 directing taxpayers to verify their tax code using the HMRC app.
- The authority warns that incorrect codes can lead to overpaying now or building up a bill to settle later.
- Common triggers for wrong codes include switching jobs, holding more than one income source, or receiving workplace perks such as a company car.
- The HMRC app lets users check their tax code and income details, view National Insurance records, access benefits and tax credits information, and see messages from HMRC.
- Access requires a Government Gateway ID, and HMRC frames the push as digital self‑service guidance rather than a new policy or reported system error.
