If you need a copy of your P60 from HMRC (Her Majesty's Revenue and Customs), you can request it through their official channels. Typically, employers provide P60 forms at the end of the tax year, summarizing your earnings and deductions. If you've misplaced yours, contact your employer first. If they are unable to assist, reach out to HMRC directly for a duplicate copy. Ensure you have necessary details such as your National Insurance number and personal information when making the request. HMRC's website or helpline can guide you through the process of obtaining a replacement P60 for your tax records.
