Unfortunately, HMRC is unable to provide a duplicate of a missing P60. It is a form completed by an Employed but not submitted to HMRC. You may contact HMRC by phone at 0300 200 3300, or you can find another means to approach them here. You’ll have your National Insurance number, which you should be able to discover on a recent pay stub.
A lost P60 may be quite inconvenient. It can cause mortgage applications to be delayed, restrict you from filing your tax return, or result in you paying too much tax!
Request a new P60 from your employer. If you cannot obtain a replacement from them, you can use your tax account to see or print the information on the P60. Contact HMRC and request the details on the P60.
If your employer is unable to assist you, you may contact HMRC. They will provide you with the information on file for your specific dates. It is not a duplicate of the P60, but it can do the same purpose. However, it may take several weeks to reach. If necessary, you might utilize this to generate a print copy.
