Total employee earnings before any deductions are applied.
Gross pay is the total amount an employee earns in a pay period before any deductions are taken — including basic salary or hourly earnings, overtime, commission, bonuses and cash allowances. Net pay is what remains after tax, National Insurance, pension contributions and other deductions are subtracted.
Gross pay is everything the employer owes the worker for the period before deductions. In a UK payroll run that normally means basic salary or hourly earnings, overtime, shift premiums, commission, bonuses, cash allowances (car, travel, on-call, London weighting), holiday pay, statutory sick pay and statutory family-leave pay, and any pay in lieu of notice.
The exclusions are where people go wrong. Employer National Insurance and employer pension contributions are employment costs, not pay — they never appear in gross pay because they were never the employee's money. Expense reimbursements are not pay either: handing back £40 someone spent on train tickets restores them to where they started. Benefits in kind sit in a third category — private medical cover or a company car may be taxable, but they are taxed through a P11D or payrolling rather than counted as cash gross pay. And salary sacrifice deliberately reduces gross pay: the employee contractually gives up salary in exchange for a benefit, so the sacrificed amount is gone from gross, which is the whole point of the arrangement and also why it drags down mortgage affordability assessments.
Four numbers describe one job and none of them are interchangeable. Basic salary is the contractual floor — the figure in the offer letter. Gross pay is what was actually earned this period, so for anyone with overtime, commission or variable allowances it moves month to month while basic salary sits still. Net pay is gross minus deductions: income tax, employee National Insurance, employee pension contributions, student loan repayments, attachment of earnings orders. Total compensation is gross plus the things that never touch the payslip — employer pension contributions, insured benefits, equity.
The failure mode is recruiters and candidates negotiating in different currencies. A candidate quoting £45,000 usually means basic salary. An employer quoting £45,000 sometimes means basic and sometimes means an expected gross including a typical bonus, which is the same number describing a materially worse offer if the bonus does not pay out. A second common error runs the other way: people cite total compensation as though it were spendable. Employer pension contributions are real value but cannot pay rent this month.
Gross pay is also the base most calculations run from. Pension contributions under a qualifying scheme, holiday pay for variable-hours workers, redundancy reference pay and most affordability checks all read gross, not net and not basic — so getting the composition wrong propagates.
Take a warehouse supervisor paid an annual basic salary of £36,000, which is £3,000 per month. In one month they work 10 hours of overtime at £25 per hour, receive a £150 on-call allowance and a £600 quarterly performance bonus.
Basic £3,000 + overtime £250 (10 × £25) + allowance £150 + bonus £600 = gross pay of £4,000 for that month. Their basic salary is unchanged at £3,000. Their gross pay is £4,000. Their net pay is whatever remains after tax, National Insurance and pension are deducted — a smaller figure again. If the employer also pays a pension contribution on top, that raises total compensation but not gross pay.
Note what the £4,000 does not tell you: it is not a run rate. Multiplying it by twelve implies £48,000, but the bonus is quarterly and the overtime was unusual. Annualising a single high-gross month is the most common way a payroll figure gets misread — in salary benchmarking, in lender affordability checks, and in an employee's own sense of what they earn.
Gross pay = basic pay (annual salary ÷ pay periods, or hours × rate) + overtime + shift premiums + commission + bonuses + cash allowances — everything earned in the period before any deduction. Net pay = gross pay − statutory deductions − voluntary deductions.
UK payslips are legally required to show earnings before and after deductions, so gross pay is not an optional line — it must be visible alongside net. Payslips must be provided on or before payday, must show the amount of any deductions that can change each pay period (tax and National Insurance being the obvious examples), and must show hours worked where pay varies with time worked. Deductions that are fixed in amount must be explained either on the payslip itself or in a separate written statement.
That hours requirement is the one payroll teams underestimate. For salaried staff on fixed pay it does not bite, but for hourly, zero-hours and variable-shift workers the payslip has to let the person reconstruct how the gross figure was reached. A payslip showing only a lump gross for someone paid by the hour is both a compliance gap and the single biggest generator of payroll queries — the employee cannot check the number, so they ask. Itemising basic hours, overtime hours, premium rates and each allowance separately turns a disputed figure into a self-explaining one.
No. Basic salary is the fixed contractual amount, while gross pay is everything actually earned in the period before deductions. For an employee whose pay is purely a fixed salary with no variable elements, the two match. For anyone earning overtime, commission, bonuses or shift allowances, gross pay is higher than basic salary and changes from period to period — which is why lenders, benchmarking exercises and pension calculations usually need to know which of the two a quoted figure refers to.
Employer pension contributions are not part of gross pay — they are an employer cost paid on top and never form part of the employee's earnings. Employee pension contributions are different: they are deducted from gross pay to reach net pay, so they are inside the gross figure. The exception is salary sacrifice, where the employee formally gives up an amount of salary in return for the employer paying it into the pension. Under sacrifice, that amount reduces gross pay itself rather than appearing as a deduction from it.
It should not. Reimbursing an expense returns money the employee already spent on the employer's behalf, so it is not earnings and is not taxable in the way pay is. It should be shown separately from gross pay on the payslip. Where a payment is a round-sum allowance rather than reimbursement of a specific receipted cost, treatment differs and it may count as pay — so the distinction between reimbursing an actual expense and paying a fixed allowance matters for how the payslip is built.
