The tax office has mistakenly linked another person’s national insurance (NI) number to mine, and now I’m being taxed as though I have dual employment.
In November, HM Revenue and Customs erroneously connected someone else’s employment information to my NI number. I have access to their employment place, the date they commenced work, their payroll ID, and their salary details.
As a result, HMRC is treating me as though I’m holding two positions, doubling my income for taxation purposes, and implementing a tax adjustment due to the perceived underpayment of last year’s taxes. This error is costing me roughly £450 each month in additional taxes and NI contributions.
I spent an hour and a half on hold before speaking to a representative who informed me that they have yet to address the issue.

Your situation is eerily reminiscent of another case where a reader was declared deceased by HMRC after they mistakenly assigned her the NI number of a deceased individual. The most alarming factor is the apparent lack of urgency in resolving these mistakes.
HMRC explained that during a review of tax codes following your job change last year, their system erroneously linked your employment information to that of another individual who shared some of your personal information. Fortunately, your actual NI numbers were not mixed up.
They have now rectified the mistake between your records and will include a refund for the overpaid tax in your upcoming paycheck. Additionally, they are offering £75 as compensation. I inquired whether, given that you could see the other person’s employment details, a data breach had been reported to the Information Commissioner’s Office.
They stated that it wasn’t necessary since the other woman’s name, address, and date of birth had not been disclosed.
