UK Payslip YTD Calculations: Complete 2026 Guide
Year-to-Date (YTD) calculations on UK payslips are essential for tracking your annual earnings, PAYE tax withholdings, National Insurance contributions, and pension deductions. Understanding these figures helps you verify payroll accuracy and prepare for tax year-end when you receive your P60.
What is YTD on a UK Payslip?
Definition
Year-to-Date (YTD) on a UK payslip shows cumulative totals from the start of the tax year (6 April 2025) through the current pay period. These figures must match your P60 form at year-end.
Why YTD Matters for UK Employees
- P60 Verification - YTD on final payslip should match your P60 form
- Tax Planning - Estimate if you'll owe or receive HMRC refund
- NI Contributions - Track toward state pension qualification
- Pension Monitoring - Ensure auto-enrolment contributions correct
- Self-Assessment - Needed if you file tax return
UK Tax Year Dates
2025/26 Tax Year:
- Start: 6 April 2025
- End: 5 April 2026
Important: YTD resets on 6 April each year, not 1 January!
UK-Specific YTD Components
1. YTD Gross Pay
What it includes:
- Basic salary/wages
- Overtime pay
- Bonuses and commissions
- Taxable allowances
- Statutory sick pay (SSP)
- Statutory maternity/paternity pay
Calculation:
YTD Gross Pay = Sum of all gross pay since 6 April 2025
Example (Monthly Pay):
- April 2025: £2,500
- May 2025: £2,500
- June 2025: £3,000 (with £500 bonus)
- July 2025: £2,500
- YTD Gross (July): £10,500
2. YTD PAYE Tax Withheld
What it is: Total income tax deducted through PAYE (Pay As You Earn)
2025/26 Tax Bands:
| Annual Income | Tax Rate |
|---|---|
| £0 - £12,570 | 0% (Personal Allowance) |
| £12,571 - £50,270 | 20% (Basic Rate) |
| £50,271 - £125,140 | 40% (Higher Rate) |
| Over £125,140 | 45% (Additional Rate) |
Tax Code Impact:
- 1257L: Standard code (£12,570 allowance)
- BR: All taxed at 20% (no allowance)
- D0: All taxed at 40%
- K codes: Negative allowance (owe extra tax)
Example:
YTD Gross: £30,000 (by January 2026)
Personal allowance: £12,570
Taxable: £30,000 - £12,570 = £17,430
Tax at 20%: £17,430 × 20% = £3,486
YTD PAYE Tax: £3,486
3. YTD National Insurance
Employee NI Rate (2025/26): 8% (reduced from 10%) Employer NI Rate: 13.8%
Thresholds:
- Primary Threshold (employee): £12,570/year (£1,048/month)
- Upper Earnings Limit: £50,270/year
- Above UEL: 2% on additional earnings
Calculation:
YTD Gross: £30,000
Above primary threshold: £30,000 - £12,570 = £17,430
YTD NI: £17,430 × 8% = £1,394.40
High Earner Example:
YTD Gross: £60,000
Up to £50,270: (£50,270 - £12,570) × 8% = £3,016
Above £50,270: (£60,000 - £50,270) × 2% = £194.60
Total YTD NI: £3,210.60
4. YTD Pension Contributions
Auto-Enrolment Minimum (2026):
- Total: 8% of qualifying earnings
- Employee: 5%
- Employer: 3%
Qualifying Earnings (QE):
- Lower limit: £6,240/year
- Upper limit: £50,270/year
- Pension calculated on earnings within this band
Calculation:
Annual salary: £30,000
Qualifying earnings: £30,000 - £6,240 = £23,760
Employee pension (5%): £23,760 × 5% = £1,188/year
YTD (9 months): £1,188 × 9/12 = £891
Salary Sacrifice:
- If using salary sacrifice scheme
- Pension deducted before tax
- Reduces PAYE and NI
- Higher take-home efficiency
YTD and Your P60 Form
At tax year-end (5 April 2026), your P60 will show:
| P60 Box | Description | Should Match Final Payslip YTD |
|---|---|---|
| Pay | Total pay for tax year | YTD Gross Pay |
| Tax deducted | Total PAYE tax | YTD PAYE Tax |
| Employee's NI contributions | Total NI paid | YTD National Insurance |
| Employee pension | YTD Pension (employee portion) |
If they don't match → contact payroll immediately!
Special YTD Situations
Multiple Jobs in Same Tax Year
PAYE Tax:
- Main job: Code 1257L (personal allowance)
- Second job: Code BR (20% on all earnings)
- May owe tax or receive refund at year-end
National Insurance:
- Each employer deducts separately
- Can't reclaim if overpaid
- Primary threshold applies to each job independently
Example:
Job 1: £25,000/year, NI paid: £993
Job 2: £15,000/year, NI paid: £196
Total NI: £1,189
(Cannot reclaim even if it seems high)
Mid-Year Job Change
Starting New Job:
- Provide P45 from previous employer
- Ensures correct tax code
- YTD from old job carries forward for tax purposes
- New employer starts fresh NI
Without P45:
- Emergency tax code applied (often BR or 0T)
- May overpay tax initially
- Corrected once tax code updated
- Can reclaim via HMRC if necessary
Bonuses and YTD
Bonus Taxation:
- Added to regular pay for month
- May push into higher rate band temporarily
- NI on total monthly pay
- YTD shows cumulative effect
Example:
Regular monthly: £2,500
December bonus: £5,000
Total for December: £7,500
Taxed at mix of 20% and 40%
YTD includes full amounts
Student Loan Repayments
Not shown as separate YTD on most payslips, but tracked:
Plan 1: 9% above £24,990/year (£2,082.50/month) Plan 2: 9% above £27,295/year (£2,274.58/month) Plan 4: 9% above £31,395/year (Scotland) Postgraduate: 6% above £21,000/year

Common YTD Mistakes
1. Confusing Calendar Year with Tax Year
- UK tax year: 6 April - 5 April
- NOT January - December
- Solution: YTD resets on 6 April
2. Not Checking YTD Monthly
- Errors compound over time
- Solution: Review every payslip
3. Ignoring Upper Earnings Limit
- NI drops from 8% to 2% above £50,270
- High earners should track this
- Solution: Understand UEL threshold
4. Salary Sacrifice Confusion
- Pension before tax reduces gross for PAYE
- But shows in total gross
- Solution: Understand "taxable gross" vs "total gross"
5. Not Saving Payslips
- Need for P60 verification
- Required for self-assessment
- Solution: Save all payslips digitally

Frequently Asked Questions
Q: When does YTD reset?
A: 6 April each year (start of UK tax year). First payslip after 6 April starts fresh.
Q: Should my final payslip YTD match my P60?
A: Yes! Your payslip dated 5 April or the last payment of the tax year should match your P60 exactly.
Q: What if my YTD doesn't match my manual calculation?
A: Contact HR/payroll immediately. This could affect your P60 and tax return.
Q: Does YTD include my bonus?
A: Yes, all taxable income including bonuses, overtime, and commissions is included in YTD gross.
Q: Can YTD go down?
A: No, YTD should only increase during the tax year (or stay the same during unpaid leave).
Q: How do I verify my NI YTD is correct?
A: For earnings between £12,570 and £50,270, multiply by 8%. Above £50,270, add 2% on excess.
Formula:
NI YTD = (min(YTD Gross, £50,270) - £12,570) × 8%
+ (max(YTD Gross - £50,270, 0)) × 2%
Q: What about pension YTD?
A: Pension YTD shows employee contributions only (usually 5%). Employer contributions (3%) shown separately if at all.
