HMRC Form P45, Details of Employee Leaving Work, is the four-part UK PAYE statement an employer issues when an employee stops working for them. Part 1 is reported to HMRC via Real Time Information (RTI), Part 1A is kept by the employee for their own tax records, and Parts 2 and 3 are handed to the new employer (or Jobcentre Plus) so the new employer can carry forward cumulative taxable pay, tax deducted, and tax code in the current tax year. If a new employer receives a flat P45 PDF or needs to complete the Part 3 new-starter section online — or if an employee has no P45 and needs the HMRC Starter Checklist — JustFill lets you complete and download the PDF in your browser.

Need to fill out Part 3 of a flat P45 PDF received by email from a new starter, prepare P45 leaving worksheets for payroll archiving, or figure out what every box on Parts 1A, 2, and 3 means? Under UK PAYE rules, every employee leaving a job is entitled to a P45 showing their Employer PAYE reference, National Insurance number, leaving date, tax code, student loan indicator, and cumulative pay and tax from 6 April up to their leaving date. Because emailed P45 PDFs exported from payroll software (Sage, Xero, BrightPay, Iris, QuickBooks) are almost always flat, uneditable PDFs, HR teams and new employers use JustFill to type directly into Part 3 (New Employer details) without printing and re-scanning.
HMRC requires employers with payroll software to generate P45s through Real Time Information (RTI) software (or HMRC Basic PAYE Tools). When a new starter emails you a flat P45 PDF and you need to fill in Part 3 digitally, or when you need an interactive P45 data-collection worksheet for payroll setup, click "Fill the blank Form P45 now" above or upload your P45 PDF in JustFill; your first clean completed download is included at no charge.
What each section of Form P45 asks for. JustFill’s AI will detect these fields automatically when you upload the PDF — review the breakdown below so you know what to enter.
3-digit HMRC office number and employer PAYE reference, employee's National Insurance number, title, surname, first name(s), and Leaving Date in DD MM YYYY format.
Checkbox indicating whether student loan deductions were continuing (`Y`), the employee's tax code at leaving (e.g. `1257L`, `BR`, `0T`), and whether it was operated on a Week 1 / Month 1 (non-cumulative) basis.
Cumulative taxable pay and income tax deducted in the current tax year (left blank if the tax code was Week 1 / Month 1, in which case pay and tax in this employment only are entered in the boxes below).
Employee payroll number, sex, date of birth, employee private address on Part 1/1A, and the leaving employer's name, address, postcode, and certification date.
New employer's PAYE reference, date new employment started, new works/payroll number, starter declaration/tax code applied, and whether P45 figures are included in the new employer's first payroll run.
A fictional UK employee, Oliver James Example, leaves Sample Digital Ltd on 30 September 2026 during the 2026/27 tax year on cumulative tax code 1257L and hands Parts 2 and 3 of his P45 to his new employer on 5 October 2026. All values are fictional.
Office No: 123 / Ref: AZ45678 · NI Number: QQ 12 34 56 C
Identifies the leaving employer's PAYE scheme and the employee's National Insurance record.
MR EXAMPLE, OLIVER JAMES · Leaving Date: 30 09 2026 · Tax Code: 1257L (Cumulative) · Student Loan: Y
Shows the cumulative personal allowance code and flags that student loan deductions were active (the new employer still checks the Starter Checklist for the specific Plan 1/2/4/5 type).
Total pay to date: £21,000.00 · Total tax to date: £2,943.00
Because the tax code is cumulative (not Week 1/Month 1), total year-to-date taxable pay and tax are carried into the new job.
New Employment Start Date: 05 10 2026 · New Payroll No: NW-209 · New Employer PAYE Ref: 456/BX98765
Completed on Part 3 by the new employer when onboarding the employee into payroll.
