Your NHS payslip contains a wealth of information — but understanding what each line means, how deductions are calculated, and what to check for errors requires guidance. Here's a complete walkthrough of every section, with worked examples.
The Standard NHS Payslip Layout
NHS payslips follow a broadly consistent format across Trusts (generated by the Electronic Staff Record — ESR), though the exact layout varies. The key sections are:
1. **Personal Details** — Name, assignment number, pay period, NI number, tax code
2. **Payments** — Basic pay, enhancements, overtime, allowances, arrears
3. **Deductions** — Tax, NI, pension, student loan, union subs, salary sacrifice schemes
4. **Year-to-Date (YTD)** — Cumulative totals for the tax year
5. **Summary** — Gross pay, total deductions, net pay, payment method
Payments Section — What Each Line Means
| Code | Description | What It Is |
|---|---|---|
| BASIC / BASIC PAY | Basic Pay | Your contracted annual salary ÷ 12 |
| HCAS / HCAS-I / HCAS-O / HCAS-F | High Cost Area Supplement | London weighting (Inner £5,593 / Outer £4,701 / Fringe £1,300) |
| UNS HRS / UNSOCIAL | Unsocial Hours | Evening/night/weekend shift enhancements |
| OT / OVRTM / OVERTIME | Overtime | Additional hours beyond your contract |
| ARR / ARREARS | Arrears/Back Pay | Pay award back pay or correction for previous months |
| RRP | Recruitment & Retention Premium | Additional payment for hard-to-fill roles |
| ON CALL / OCA | On-Call Allowance | Payment for being available outside normal hours |
| EXC DAY / EXCESS | Excess Travel | Reimbursement for additional travel costs |
Deductions Section — Understanding Each Deduction
| Code | Description | How It's Calculated |
|---|---|---|
| PAYE / TAX | Income Tax | Based on tax code (usually 1257L), applied cumulatively across the year |
| NI / ENIC | National Insurance | 8% on earnings £12,570–£50,270/yr, 2% above (monthly thresholds apply) |
| PENSION / NHSPS / SUPRN | NHS Pension | Tiered rate (5.2%–12.5%) on total pensionable pay |
| STU LOAN / SL | Student Loan | Plan 1: 9% over £24,990/yr; Plan 2: 9% over £27,295/yr; Plan 5: 9% over £25,000/yr |
| UNION / RCN / UNISON | Union Subscription | Varies by union and band — typically £15–£30/month |
| AEO / AOE | Attachment of Earnings | Court-ordered deductions (child maintenance, debt orders) |
| CYCLE / C2W | Cycle to Work | Salary sacrifice scheme deduction |
| CHVCH / CHILDCARE | Childcare Vouchers | Salary sacrifice for childcare (legacy scheme) |
Worked Example — Band 5 Entry Monthly Payslip
A Band 5 nurse at entry (£32,073/year), no London weighting, no overtime, Plan 2 student loan:
| Line | Amount |
|---|---|
| Basic Pay | £2,673 |
| Unsocial Hours (~15% average) | +£401 |
| Gross Pay | £3,074 |
| Income Tax (1257L) | -£374 |
| National Insurance (8%) | -£181 |
| NHS Pension (8.3%) | -£255 |
| Student Loan Plan 2 | -£72 |
| Union (RCN) | -£20 |
| Total Deductions | -£902 |
| Net Pay | £2,172 |
This example shows ~29.3% of gross pay going to deductions. The actual split varies with overtime, enhancements, and personal circumstances.
Year-to-Date (YTD) — Why It Matters
The YTD section shows your cumulative totals since 6 April (the start of the tax year). This is crucial for:
• **Checking HMRC is applying the correct tax**: Tax is calculated cumulatively. HMRC tracks whether you've been over- or under-taxed in previous months and adjusts. If you see a month where tax was unusually high or low, the YTD section reveals whether a correction was applied.
• **Pension tier assessment**: Your pension contribution tier is based on your annual pensionable pay. If YTD earnings suggest you'll cross a tier boundary, your rate may change mid-year.
• **Student loan reconciliation**: The Student Loans Company uses your YTD earnings to reconcile deductions annually.
• **Tax return preparation**: If you need to file a Self Assessment, your YTD figures at March should match your P60.
💡Check Your Tax Code Every April — Your tax code changes when your personal allowance or circumstances change. Common errors: emergency tax code (0T or BR) applied after changing Trust, old benefit-in-kind adjustments carried forward, marriage allowance not applied. An incorrect tax code can cost hundreds per month. Your tax code appears on every payslip — check it matches your HMRC Personal Tax Account.
Common Payslip Errors to Watch For
1. **Wrong spine point** — Check your basic pay matches your band and step. If you were due an increment (anniversary of starting date), verify it's been applied.
2. **Missing HCAS** — If you work in a London-area trust, you should see HCAS. Inner London = £5,593/yr, Outer = £4,701, Fringe = £1,300.
3. **Incorrect pension tier** — If your salary crossed a threshold mid-year, check the rate changed correctly (and not prematurely).
4. **Emergency tax code** — Shows as 0T, BR, or a code with W1/M1 suffix. This means HMRC doesn't have your correct details. Contact payroll and HMRC.
5. **Missing overtime/enhancements** — Cross-reference with your rota/timesheet. Enhancements should appear separately from basic pay.
6. **Student loan plan type** — If you're on Plan 2 but being deducted as Plan 1, the threshold is wrong. Check your Student Loans Company account.
7. **Pay award not applied** — After April, check your basic pay has increased by the award percentage.
8. **Incorrect hours** — For part-time staff, check your WTE fraction matches your contract.
How to Challenge a Payslip Error
If you spot an error:
1. **Document it**: Screenshot the payslip, note the discrepancy, and calculate the correct figure
2. **Contact payroll**: Most Trusts have an online payroll query system through ESR. Email or phone if urgent.
3. **Escalate if needed**: If payroll doesn't resolve within one pay cycle, escalate to your line manager and HR
4. **Involve your union**: For persistent errors or systemic issues, your union rep can raise it formally
5. **HMRC for tax issues**: If your tax code is wrong, contact HMRC directly (0300 200 3300) — don't wait for payroll to fix it
Most errors are corrected in the following month's payroll. Underpayments are typically backdated; overpayments may be recovered in instalments.
Accessing Your Payslip
Most NHS Trusts now provide digital payslips through ESR Self-Service (accessible via NHS.net or the ESR portal). You can:
• View current and historical payslips
• Download PDF copies for mortgage/visa applications
• Access your P60 (end-of-year tax summary)
• View your Total Reward Statement (including pension and other benefits)
• Update personal details (bank account, address)
If you've left the NHS and need historical payslips, contact your former Trust's payroll department. They're required to retain records for 6 years.
