Free Payslip Generator: The Complete UK Guide for 2026/27

If you employ even one person — whether that’s a full-time member of staff, a part-time assistant, or yourself as a limited company director — you have a legal obligation to provide an itemised payslip every time you pay them. For small business owners, sole director companies, and freelancers who occasionally take on help, buying dedicated payroll software just to produce a payslip can feel like overkill. This guide explains exactly what a payslip must legally contain, how to calculate the figures correctly for 2026/27, and how to generate a professional payslip in under two minutes using our free tool.

What is a payslip generator?

A payslip generator is a tool that takes basic employment details — an employee’s salary, tax code, pension contribution, and pay period — and produces a formatted, itemised pay statement showing gross pay, each deduction, and net (take-home) pay. Unlike full payroll software, a standalone payslip generator does not submit anything to HMRC on your behalf; it simply produces the document your employee is legally entitled to receive.

This distinction matters. Full payroll software (Sage, Xero Payroll, BrightPay, and similar) must be recognised by HMRC to file Real Time Information (RTI) — the system that reports PAYE tax and National Insurance to HMRC every time you pay someone. A payslip generator is a document tool, not a filing tool. If you employ staff, you still need HMRC-recognised payroll software (or HMRC’s own free Basic PAYE Tools) to meet your RTI obligations — but you can use a free generator like ours to produce the actual payslip document your staff see.

What must a UK payslip legally include?

Under the Employment Rights Act, every employer in the UK must provide employees and workers with a written, itemised pay statement on or before each payday. The legal minimum requirements are:

Requirement	Details
Gross pay	The total pay before any deductions are taken
Itemised deductions	The amount of each deduction and what it is for (tax, NI, pension, student loan, etc.)
Net pay	The final take-home amount after all deductions
Method of payment	If different parts of the pay are made in different ways
Hours worked	Required if pay varies according to hours worked (e.g. hourly or variable pay)

Many employers also include additional information as good practice, even though it isn’t always a strict legal requirement: the employee’s tax code, National Insurance category letter, payroll or employee number, employer PAYE reference, and year-to-date (cumulative) figures for tax, NI, and pension. Our free generator includes all of these fields.

How payslip tax and NI figures are calculated

Getting the numbers right on a payslip matters — both for your employee’s trust and for your own records if HMRC ever asks questions. Here is exactly how the automatic calculation works for 2026/27:

Income Tax

The standard Personal Allowance for 2026/27 is £12,570 — the amount of annual income that is tax-free. Above that:

Band	Annual income	Rate
Personal Allowance	Up to £12,570	0%
Basic rate	£12,571 – £50,270	20%
Higher rate	£50,271 – £125,140	40%
Additional rate	Over £125,140	45%

The annual tax due is calculated first, then divided by the number of pay periods in the year (12 for monthly, 52 for weekly, 13 for 4-weekly) to arrive at the correct amount for that specific payslip.

National Insurance

Employee Class 1 National Insurance for 2026/27 is charged at 8% on earnings between £12,570 and £50,270, and 2% above that threshold. Like Income Tax, this is calculated on the annualised salary and then divided by the pay frequency.

Pension contributions

If a pension contribution percentage is entered, it is deducted from gross pay before Income Tax is calculated (this reflects the most common "net pay arrangement" or salary sacrifice method used by most UK workplace pensions), which reduces the taxable amount and therefore the tax due.

Student loan repayments

If applicable, student loan repayments are calculated at 9% of income above the relevant plan threshold (Plan 1: £24,990, Plan 2: £27,295, Plan 4: £31,395, Plan 5: £25,000 for 2026/27), divided by the pay frequency.

Worked example

An employee on a £42,000 annual salary, paid monthly, with a 3% pension contribution:

Item	Amount
Monthly gross pay	£3,500.00
Income Tax	−£469.50
National Insurance	−£196.20
Pension (3%)	−£105.00
Net pay	£2,729.30

Free payslip generator vs paid payroll software

It’s worth being clear about when a free payslip generator is the right tool, and when you actually need full payroll software:

Situation	What you need
You employ yourself as a sole director, paying a small salary	Payslip generator is often sufficient, but you must still file RTI — check if your accountant handles this, or use HMRC Basic PAYE Tools alongside the generator
You employ 1–9 staff and want the cheapest compliant option	HMRC’s free Basic PAYE Tools for RTI filing, plus our generator for a nicer-looking payslip if desired
You employ 10+ staff, or need auto-enrolment pension handling	Dedicated HMRC-recognised payroll software (Sage, BrightPay, Xero Payroll, etc.)
You want to check an existing payslip is correct	Use our Payslip Checker instead

Choosing the right pay frequency

One decision that affects every payslip you produce is pay frequency — monthly, weekly, or 4-weekly. This isn’t just an administrative preference; it changes how tax and NI are calculated for each period, and it affects your employee’s cash flow.

Frequency	Pay periods/year	Best suited to
Monthly	12	Most salaried office and professional roles; simplest for annual salary planning
4-weekly	13	Retail, hospitality, and shift-based roles where rotas run in 4-week cycles
Weekly	52	Manual labour, construction, and casual or variable-hours work

Whichever frequency you choose, the same annual Personal Allowance and tax bands apply — the calculation simply divides the annual figures by the number of periods. Our generator handles this automatically when you switch between the three options, recalculating tax, NI, pension and student loan deductions for the correct period length.

Payslips for different types of workers

Not every payslip looks the same, because not every working arrangement is the same. Here’s how the requirements and calculations differ:

Full-time salaried employees

The simplest case: a fixed annual salary divided evenly across each pay period. Tax code, NI category, and any recurring deductions (pension, student loan) stay consistent from month to month unless circumstances change.

Part-time and variable-hours workers

For part-time staff, enter their annualised salary based on actual contracted hours (not a full-time equivalent), and remember the legal requirement to show hours worked on the payslip when pay varies by hours. If someone works irregular shifts, you may need to recalculate their gross pay each period based on actual hours logged, then let the generator calculate tax and NI on that period’s specific earnings.

Company directors

Many limited company directors pay themselves a modest salary (often at or near the Personal Allowance or the NI secondary threshold) and take the remainder of their income as dividends, since dividends are not subject to National Insurance. See our Director Salary vs Dividend Calculator to work out the most tax-efficient split before generating your payslip.

Casual and zero-hours staff

For genuinely irregular work, each payslip may show a different gross figure depending on hours actually worked that period. Holiday pay for these workers is often calculated using the 12.07% accrual method — see our Holiday Pay Calculator for the exact figures.

What happens if a payslip is wrong?

If an employee spots an error on their payslip — wrong tax code, incorrect deduction, missing overtime — the first step is always to correct it directly with the employer, ideally before the next payroll run. Overpaid tax is usually resolved automatically through the PAYE system in a later period, or via a tax code adjustment from HMRC. Underpaid tax can result in a bill at year-end if not caught quickly, so it’s worth double-checking a new payslip against expected figures — our Payslip Checker is built exactly for this: enter your gross pay, tax code, and the tax/NI shown on your payslip, and it flags any mismatch against what HMRC rates say you should be paying.

If an employer refuses to provide a payslip at all, or refuses to correct a genuine error, an employee can raise this with ACAS or, in persistent cases, bring a claim to an Employment Tribunal. Getting the payslip right the first time avoids all of this friction.

Digital vs paper payslips

There is no legal requirement for payslips to be on paper — a PDF sent by email, or a document generated through a tool like ours and shared digitally, satisfies the "written" requirement under the Employment Rights Act, provided the employee can access and retain a copy. This is why our generator is built around producing a downloadable PDF via your browser’s print function rather than requiring specialist software: it works identically on a laptop, phone, or tablet, and the result is a standard PDF file your employee can save, print, or forward to a mortgage lender or letting agent if needed.

Common payslip mistakes to avoid

• Using the wrong tax code — an outdated or emergency tax code will produce incorrect tax figures. Always use the employee’s current tax code from their P45, starter checklist, or most recent HMRC notification.
• Forgetting to itemise deductions — a payslip that only shows "deductions: £500" without breaking down tax, NI, and pension separately does not meet the legal requirement for an itemised statement.
• Missing hours worked for variable-pay staff — if pay changes based on hours (common for part-time or zero-hours workers), the number of hours paid for must be shown.
• Not keeping records — employers are legally required to keep payroll records, including payslips, for at least 3 years.

Why not just use a Word or Excel template?

A quick search turns up plenty of free payslip templates for Word and Excel. These can work, but they come with a hidden risk: the tax and NI figures are entirely manual. You either have to calculate them yourself using the current year’s bands and thresholds, or worse, reuse last year’s template with last year’s numbers still baked in. Every April, Income Tax bands, National Insurance thresholds, and student loan repayment rates can all change — a static template doesn’t know that.

Our generator solves this by calculating tax and NI live, using the current 2026/27 rates, every time you use it. There’s no risk of accidentally issuing a payslip with outdated figures because you forgot to update a spreadsheet formula. And because it runs in the browser rather than requiring Word or Excel, it works identically whether you’re on a laptop, phone, or a work computer that doesn’t have Microsoft Office installed.

Using this tool as a freelancer or micro-agency

If you run a small agency, studio, or partnership and occasionally bring on a part-time employee or apprentice, you may not want to commit to a monthly payroll software subscription for a single member of staff. In this situation, many small business owners use HMRC’s free Basic PAYE Tools to handle the RTI filing requirement (available for employers with fewer than 10 employees), and a generator like ours to produce a clean, professional-looking payslip to hand or email to the employee. This combination costs nothing and takes only a few minutes each pay period, while still meeting your legal obligations as an employer.
