7 Common Umbrella Pay Deductions Explained for Supply Teachers
You’ve just received your first payslip through an umbrella company. You worked a full week, calculated what you expected to earn, then saw the net pay figure. It’s significantly less than anticipated. You scan through deductions you don’t understand: Income Tax, National Insurance, “Employer’s NIC,” “Umbrella Margin,” “Holiday Pay Accrual.”
If this feels familiar, you’re not alone. Thousands of supply teachers work through umbrella companies, yet many find payslip deductions confusing. This guide demystifies the seven most common deductions, explains what they mean, and helps you verify your payslip is correct.
Important disclaimer: This article provides general information about umbrella company deductions. It is not personal tax or financial advice. For tailored guidance on your specific circumstances, consult a qualified accountant or tax adviser.
Understanding Umbrella Companies Basics
When you work through many supply agencies, you’re often paid via an umbrella company. The school pays the agency, the agency pays the umbrella company, and the umbrella company employs you, processes payroll, and pays you as an employee under PAYE (Pay As You Earn).
Understanding how agencies pay supply teachers compared to direct hire provides broader context.
Deduction 1: Income Tax
What it is: Tax on your earnings, deducted before you receive pay.
How it’s calculated: Using PAYE based on your tax code (commonly 1257L for 2024/25). Personal allowance: £12,570 annually. Above this:
- 20% on £12,571-£50,270
- 40% on £50,271-£125,140
- 45% over £125,140
Example: Weekly earnings of £500:
- Weekly personal allowance: approximately £242
- Taxable: £258
- Tax deducted: approximately £51.60 (20%)
What to check: Your tax code is correct. Emergency codes (1257L M1 or W1) mean you won’t benefit from your full personal allowance, resulting in overpayment.
Understanding pay structures connects to the ultimate guide to supply teacher pay and benefits.
Deduction 2: Employee National Insurance
What it is: Contributions towards state benefits including State Pension, unemployment support, and NHS funding.
How it’s calculated: Class 1 NI for 2024/25:
- 0% up to £242 per week
- 12% on £242-£967 per week
- 2% above £967 per week
Example: Weekly earnings of £500:
- Earnings above £242: £258
- NI deducted: approximately £30.96 (12%)
Why it matters: NI contributions count towards your State Pension.
Deduction 3: Employer’s National Insurance
What it is: National Insurance the umbrella company pays on your behalf as your employer (13.8% on earnings above £175 per week for 2024/25).
The crucial bit: This comes from your assignment rate before calculating your gross pay.
Example:
- Agency pays umbrella: £180 per day
- Minus Employer’s NIC: approximately £23.50
- Your gross pay: approximately £156.50
Why this matters: Employer’s NIC significantly impacts take-home pay. It’s legal and standard, but many don’t realise this “above the line” deduction happens.
What to check: The assignment rate should clarify if it’s inclusive or exclusive of Employer’s NIC.
Deduction 4: Umbrella Company Margin
What it is: The umbrella company’s fee for processing payroll, providing employment rights, and managing compliance.
Typical amounts: Usually £15–£30 per week, though some charge 3–4% instead.
Example: £20 per week deducted from your assignment rate before calculating gross pay.
What to check:
- Margin amount was clearly stated when signing up
- No hidden fees beyond agreed margin
- Fee structure hasn’t changed without notification
Red flags: Umbrellas advertising “90% retention” or “98% take-home” often use questionable tax schemes. Stick with FCSA-accredited umbrella companies.
Deduction 5: Holiday Pay Accrual
What it is: A portion of your pay set aside to fund statutory holiday entitlement (5.6 weeks annually, or 28 days).
How it’s calculated: Usually 12.07% of your gross earnings.
Example: Gross pay of £500:
- Holiday pay accrued: approximately £60.35
- Deducted from weekly pay
- Received when you take holiday or at year-end
Two approaches:
- Accrual (most common): Deducted weekly, paid out when booking holiday
- Rolled-up: Added to weekly pay immediately
What to check:
- Which approach your umbrella uses
- Holiday pay is correctly accrued and tracked
- How to claim accrued holiday pay
Understanding these structures helps whether considering how to transition from supply teaching to full-time roles.
Deduction 6: Pension Contributions
What it is: Contributions to a workplace pension scheme. Umbrella companies must enrol eligible employees.
Typical deductions: Minimum for 2024/25:
- Employee: 5% of qualifying earnings
- Employer: 3% of qualifying earnings
Qualifying earnings: £6,240-£50,270 annually.
Example: Weekly earnings of £500 (£26,000 annually):
- Qualifying earnings: £19,760 annually
- Weekly pension deduction: approximately £19 (5%)
Your options:
- Remain enrolled and benefit from employer contributions (recommended)
- Opt out within one month for full refund
- Stop contributing after one month (lose employer contributions)
Why it matters: Reduces immediate take-home but builds retirement savings with employer contributions.
Deduction 7: Other Common Deductions
Student Loan Repayments
Thresholds for 2024/25:
- Plan 1: £24,990 annually (9% above)
- Plan 2: £27,295 annually (9% above)
- Plan 4: £31,395 annually (9% above)
- Postgraduate: £21,000 annually (6% above)
Example: £600 weekly (£31,200 annually) on Plan 2:
- Above threshold: £3,905
- Weekly deduction: approximately £6.75
Union Subscriptions
What it is: Membership fees for teaching unions (NEU, NASUWT, etc.), typically £10–£20 per month.
Why it matters: Provides professional support, legal advice, and representation—particularly valuable for supply teachers.
Apprenticeship Levy
What it is: Levy umbrella companies pay if annual payroll exceeds £3 million. Shouldn’t appear as individual deduction on your payslip.
Understanding what are the daily duties of a supply teacher includes understanding pay structures.
Worked Payslip Example
Assignment details: 5 days at £180 per day = £900 weekly assignment rate
From assignment rate (before gross pay):
- Assignment rate: £900.00
- Minus Employer’s NIC: -£100.05
- Minus Umbrella margin: -£25.00
- Gross pay: £774.95
From gross pay:
- Income Tax: -£106.99
- Employee NI: -£63.95
- Holiday pay accrual: -£93.54
- Pension: -£19.00
- Total deductions: -£283.48
Net pay: £491.47 Holiday pay held: £93.54
Your Payslip Verification Checklist
- ✓ Days/hours match timesheet
- ✓ Assignment rate reflects agreement
- ✓ Tax code correct (not emergency code)
- ✓ Employer’s NIC at 13.8%
- ✓ Umbrella margin matches agreed fee
- ✓ Income Tax appropriate for earnings
- ✓ Employee NI at correct rate (12%)
- ✓ Holiday pay correctly accrued/paid

- ✓ Year-to-date figures accumulating correctly
If anything seems wrong: Contact your umbrella company immediately. Keep copies of all payslips and timesheets.
Understanding IR35
What is IR35? Tax legislation determining if a worker should be classified as employee or self-employed. Since 2021, schools determine IR35 status for agency workers.
Impact: Most supply roles are “inside IR35,” meaning you’re treated as an employee for tax—why umbrella arrangements are standard.
What this means:
- You pay tax and NI like an employee
- You receive employment rights
- You cannot work through a limited company without equivalent tax
For context, explore how supply teaching can build your teaching experience.

Understanding Your Worth
Umbrella pay deductions can feel overwhelming when take-home pay is significantly less than expected. But understanding each deduction empowers you to verify correctness, budget effectively, and make informed decisions.
These deductions aren’t arbitrary. Income Tax and NI fund essential services and your state pension. Employer’s NIC is a legal requirement. Umbrella margins cover legitimate services. Holiday pay ensures compensation for time off. Pension contributions build long-term security.
The key is transparency. Reputable umbrella companies and agencies clearly explain deductions upfront. If yours doesn’t, or if deductions seem incorrect, challenge them.
Supply teaching offers flexibility, variety, and invaluable experience. Understanding your pay ensures fair compensation for the vital work you do. Armed with this knowledge, you can confidently review your payslip, verify deductions, and focus on what matters most: making a positive difference in pupils’ lives.
