UK payroll jargon, translated

Updated June 2026 · Bookmark-worthy

UK payroll has a dialect all of its own, and if you're an overseas employer it can feel like a second language on top of a second language. Here's every term you'll actually meet, in plain English, plus the dates that matter.

Terms that confuse everyone

Tax year, runs 6 April to 5 April, not the calendar year. Payroll resets each 6 April.
Tax month, runs from the 6th of one month to the 5th of the next (this is why HMRC payment deadlines look odd).
Tax code, tells payroll how much tax-free pay an employee gets (e.g. 1257L). Wrong codes are the #1 cause of "my tax looks wrong" queries.
Gross vs net pay, gross is before deductions; net is what lands in the employee's bank.
Qualifying earnings, the slice of pay used to calculate auto-enrolment pension contributions.
Employer's NI, not deducted from the employee: an extra cost on top of gross salary. Calculate the true cost of a hire.

The dates that matter

When	What
On or before payday	FPS due to HMRC (every single payday)
22nd of the month	PAYE/NI for the previous tax month due to HMRC (electronic; 19th by post)
6 April	New tax year, new rates and thresholds apply
31 May	P60s must be given to all employees
6 July	P11D / benefits returns due
31 January	Self Assessment online filing & payment deadline
Within 6 weeks of duties start	Eligible staff enrolled in a workplace pension (declaration to TPR within 5 months)
