P45, P60 and P11D: the employer year-end documents explained

P45, P60 and P11D: the employer year-end documents explained


 

Three forms, three different moments

Employers deal with three similarly named HMRC forms, and mixing them up causes real problems: P60s handed out like P45s, P11Ds forgotten entirely, Class 1A National Insurance paid late. Each form belongs to a different moment in the employment story. Get the timing and the purpose straight, and payroll year-end becomes routine.

P45: when an employee leaves

The P45 is the leaving form. When an employment ends, the employer must produce a P45 without unreasonable delay, normally on the final payday. It comes in four parts with distinct destinations:

  • Part 1 goes to HMRC.
  • Parts 1A, 2 and 3 go to the employee. Part 1A is for the employee's own records, while Parts 2 and 3 go to the new employer or to Jobcentre Plus, so the next payer can put the employee on the right tax code.

The P45 shows total pay and tax deducted in that employment up to the leaving date, plus the tax code in use. A common and costly mistake is issuing a P45 to someone who is still employed, perhaps after a department move or a return from long-term leave. In HMRC's eyes the P45 means the employment has ended, and issuing one in error creates a tax code mess that can take months to unwind.

P60: the end-of-year summary

The P60 is the annual certificate that every employee on the payroll at 5 April must receive by 31 May. It summarises the whole tax year: total pay, income tax deducted, employee National Insurance, and statutory payments such as sick pay and maternity pay.

Unlike the P45, the P60 is for the employee to keep. There is nothing to send to HMRC, because the same figures have already been reported through Real Time Information submissions during the year. Employers sometimes assume the P60 is optional for staff who left during the year. It is not optional for anyone on the payroll at 5 April, including part-time and casual staff, and late P60s are one of the most common employee complaints to payroll teams each spring.

P11D and P11D(b): benefits, expenses and Class 1A

The P11D reports taxable benefits and expenses provided to employees and directors: company cars, private medical insurance, beneficial loans, accommodation and similar perks. The deadline is 6 July following the tax year, with one P11D per employee who received benefits.

Sitting alongside it is the P11D(b), the employer's declaration of Class 1A National Insurance due on those benefits. Two points catch employers out every year. First, the P11D(b) is still required even when there is nothing to pay, for example where all benefits were payrolled during the year; HMRC expects the nil declaration. Second, the Class 1A payment itself is due by 19 July, or 22 July if paid electronically, and interest and penalties apply from the day after.

Getting benefit figures right matters more than many employers realise. Company car benefit depends on list price, CO2 emissions and fuel type, and a single wrong emissions figure can misstate the tax for the whole year. Beneficial loans, where an employee borrows at below the official rate of interest, are another frequent source of errors.

A simple year-end calendar for employers

Pin these dates where the payroll team can see them:

  • 5 April: the tax year ends.
  • 19/22 April: the final Full Payment Submission for the year is due.
  • 31 May: P60s issued to all employees on the payroll at 5 April.
  • 6 July: P11Ds and the P11D(b) submitted to HMRC.
  • 19/22 July: Class 1A National Insurance paid.

Use payroll software that produces all three forms, reconcile the P11D figures back to the payroll records before submitting, and keep copies for at least three years. HMRC compliance checks routinely ask for them, and reconstructing a year's benefits from memory is nobody's idea of a good week.

For growing businesses, employer obligations multiply quickly, and a missed P11D(b) or a late batch of P60s is exactly the kind of avoidable error that damages trust with staff. Finex Outsourcing is a Global Business Services provider supporting UK employers with dependable payroll administration, so every form lands on time. The official guidance on all three forms is at gov.uk.
