Why Your Umbrella Company Payslip Shows Employer's NI: Deductions Explained

You’ve started a new contract through an agency. They quoted you £20/hour. You worked 40 hours. You expected £800. Your payslip shows £550. The deductions include “Employer’s National Insurance,” “Apprentice Levy,” and “Margin” — all taken out before your tax and NI are even calculated. What just happened?

This is one of the most common shocks for workers new to umbrella companies. A Reddit post captured it perfectly:

£20 × 40 hrs = £800. Deductions: Margin £17.50, Employer’s National Insurance £90, Apprentice Levy £4. Total Remaining Funds £688.50. Then £688.50 is subject to my tax code and NI. That week I got £550. Wtf.

The comments were split between “looks about right” and “this is a scam.” Neither is quite the full picture. Here’s what’s actually happening, why it’s legal, and what you should check.

You’re an Employee of the Umbrella Company, Not the End Client

The first thing to understand is your employment relationship. When you work through an umbrella company:

The end client needs a worker and engages a recruitment agency to find one
The agency finds you and routes you through an umbrella company for payroll
The umbrella company employs you directly — you are on their payroll, they operate PAYE, and they are listed as your employer with HMRC
The agency pays the umbrella company an assignment rate for your time, and the umbrella pays you a wage from that

According to HMRC’s guidance on working through an umbrella company, the umbrella company “employs you and pays your wages through PAYE. It does not find temporary work for you. The recruitment agency does this.”

This means you are an employee, not self-employed, not a contractor, and not a freelancer. You have the same employment rights as any other employee — including paid holiday, Statutory Sick Pay, and auto-enrolment into a workplace pension. (More on this below, because one Reddit commenter got this wrong.)

The Assignment Rate Is Not Your Wage

This is the single most misunderstood thing about umbrella working, and it’s the root of the £800 → £550 shock.

The £20/hour rate the agency quoted you is the assignment rate — the amount the agency pays the umbrella company for each hour you work. It is a contract price, not a wage. It has to fund the full cost of employing you:

Your gross taxable pay
Employer’s National Insurance (15% on earnings above the secondary threshold of £5,000/year for 2025/26)
Apprenticeship Levy (0.5% of the employer’s pay bill, if it exceeds £3 million)
Employer pension contributions (if applicable)
Holiday pay
The umbrella company’s margin (typically £15–£25/week)

Only what’s left after those employment costs are met becomes your gross pay. Your Income Tax and employee National Insurance are then deducted from that gross pay to give your net take-home.

Here’s how the Reddit poster’s £800 breaks down:

Item	Amount	What it is
Assignment rate (£20 × 40 hrs)	£800.00	What the agency pays the umbrella
Umbrella margin	−£17.50	The umbrella’s fee for running payroll
Employer’s NI	−£90.00	15% on earnings above the £96/week secondary threshold
Apprenticeship Levy	−£4.00	0.5% of pay bill (umbrella exceeds £3m threshold)
Gross pay	£688.50	Your taxable wage — what tax/NI is calculated on
Income Tax (approx.)	−£75.27	20% on pay above £242/week Personal Allowance
Employee NI (8%)	−£63.23	8% on earnings between £242 and £967/week
Net take-home	~£550.00	What lands in your bank account

The key line is gross pay = £688.50. That’s not a deduction from £800 — it’s the result of setting your wage after the employment costs are covered. The £800 was never your wage; it was the total pot from which an entire employment had to be funded.

Why Employer’s NI Comes Out of Your Rate

In a normal job, your employer pays employer’s NI on top of your salary — you never see it on your payslip. So why does it appear on an umbrella payslip?

Because in a normal job, the employer has revenue from their business to cover employment costs. An umbrella company’s only revenue is the assignment rate minus its margin. It has no other source of income. So the employer’s NI — which is a real cost the umbrella must pay to HMRC — has to come from the assignment rate.

As HMRC’s employer guidance confirms, employer’s NI is 15% on all earnings above the secondary threshold (£96/week, or £5,000/year, for 2025/26). For someone earning £800/week, the employer’s NI is roughly £106.20 (15% of £800 minus the threshold). The Reddit poster’s £90 figure is in the right ballpark — the exact amount depends on how the threshold is applied across the pay period.

The April 2025 increase from 13.8% to 15%, combined with the secondary threshold dropping from £9,100 to £5,000, made this noticeably worse for umbrella workers. According to industry analysis, the change equated to an 8.7% increase in employer NI costs — all of which comes out of the assignment rate before gross pay is set.

The Apprenticeship Levy: Why It’s on Your Payslip

The Apprenticeship Levy is 0.5% of an employer’s annual pay bill, but only employers with a pay bill over £3 million actually pay it — because there’s a £15,000 annual allowance that fully offsets the levy for employers below that threshold. According to HMRC’s Apprenticeship Levy guidance, 0.5% of £3 million is £15,000, so the allowance zeroes out the levy for smaller employers.

Large umbrella companies — which process payroll for thousands of workers — easily exceed the £3 million threshold. So they pay the levy, and like employer’s NI, it’s an employment cost funded from the assignment rate before gross pay is calculated.

For the Reddit poster, the £4/week Apprenticeship Levy deduction is 0.5% of their weekly pay — consistent with how the levy is calculated. It’s a small amount per worker, but it adds up across the umbrella’s entire workforce.

The Umbrella Margin: What You’re Paying For

The margin (£17.50/week in the Reddit post) is the umbrella company’s fee for running payroll, handling HMRC compliance, employing you, and managing the administrative overhead. Typical margins range from £15 to £25 per week, though some umbrellas charge more.

This is the umbrella’s actual revenue. Everything else — employer’s NI, Apprenticeship Levy, pension contributions, holiday pay — is passed through to HMRC or to you. The margin is the only amount the umbrella keeps.

If your margin is significantly higher than £25/week, or if it’s charged as a percentage of your rate rather than a flat fee, that’s worth questioning. A percentage-based margin on a high day rate can cost you far more than a flat weekly fee.

How to Read Your Umbrella Payslip

Umbrella payslips are confusing because they show two layers of deductions that most workers have never seen before. Here’s how to read one:

Layer 1: Employment costs (before gross pay)

These are deducted from the assignment rate to arrive at your gross pay:

Umbrella margin — the umbrella’s fee
Employer’s NI — 15% on earnings above the secondary threshold
Apprenticeship Levy — 0.5% of pay bill (if the umbrella exceeds £3m)
Employer pension contribution — if auto-enrolled and not opted out
Holiday pay — if paid as “rolled up” (included in each payslip rather than paid when you take leave)

After these are deducted, you get your gross pay — the figure your tax code and employee NI apply to.

Layer 2: Personal deductions (from gross pay)

These are the standard PAYE deductions every employee sees:

Income Tax — based on your tax code and bands
Employee National Insurance — 8% on earnings between £242/week and £967/week, 2% above that
Employee pension contribution — if auto-enrolled and not opted out
Student loan repayments — if applicable

After these are deducted, you get your net pay — what lands in your bank account.

The payslip presentation issue

One important detail: employer’s NI should appear above gross pay (as an employment cost that reduces what gross pay is set at), not below it as a deduction from gross pay. If your payslip shows employer’s NI listed alongside Income Tax and employee NI as a deduction from gross pay, that’s a presentation error. The gov.uk guidance on umbrella payslips is clear: employer’s NI is an employment cost met from the assignment rate, not a deduction from your gross pay.

This distinction matters because it affects whether your gross pay figure is correct. If employer’s NI is incorrectly shown as a deduction from gross pay rather than a cost before gross pay is set, your gross pay figure may be wrong — which means your tax and employee NI calculations could be wrong too.

You DO Have Employment Rights (Despite What One Commenter Said)

One Reddit commenter claimed: “In return you get no sickness pay, no holiday pay or any other time off pay. No employment rights, etc.”

This is wrong. Because you are an employee of the umbrella company, you have the same employment rights as any other employee. According to HMRC’s guidance:

“As an employee of an umbrella company, you have the same employment rights as other employees.”

This includes:

Paid holiday — at least 5.6 weeks (28 days including bank holidays) per year. Some umbrellas pay this as “rolled up” holiday pay (an additional amount in each payslip); others pay it when you take leave. Either way, you are legally entitled to it.
Statutory Sick Pay — if you meet the eligibility criteria (earning above £125/week). From April 2026, SSP is payable from the first day of sickness, not the fourth.
National Minimum Wage / National Living Wage — your take-home pay after all deductions must not fall below NMW/NLW for your age group. If it does, the umbrella is breaking the law.
Auto-enrolment into a workplace pension — the umbrella must enrol you and make employer contributions if you’re eligible and don’t opt out.
Protection against unfair dismissal — from April 2026, under the Employment Rights Act 2025, the qualifying period drops to 6 months for most workers.

The commenter may have been confusing umbrella workers with limited-company contractors working outside IR35, who genuinely have no employment rights because they are their own employer. Umbrella workers are inside IR35 and are employees — a fundamentally different position.

The Real Problem: Rate Transparency

The deductions themselves are legitimate. The problem is transparency — agencies often quote the assignment rate (£20/hour) without explaining that it’s not your wage. The worker signs up expecting £800/week and discovers £550/week after all employment costs and personal deductions.

Since 6 April 2020, employment businesses are required by law to give you a Key Information Document (KID) before you agree to terms. According to HMRC’s KID guidance, the KID must show:

The umbrella company’s name
The assignment rate paid to the umbrella
All deductions the umbrella will make (margin, employer’s NI, Apprenticeship Levy, pension)
Your minimum gross pay
Your holiday entitlement and how holiday pay is paid

If you didn’t receive a KID before starting, the agency is in breach of the Conduct of Employment Agencies and Employment Businesses Regulations 2003. Request one immediately — it’s your legal right, and it should show you exactly where the money goes.

When Umbrella Working Makes Sense (and When It Doesn’t)

Umbrella companies exist because they solve a real problem: many end clients and agencies won’t engage limited-company contractors inside IR35 directly, so they route workers through an umbrella for PAYE compliance. The umbrella takes on the employer responsibilities, and the worker gets paid through PAYE without needing their own limited company.

Umbrella working can make sense when:

Your contract is inside IR35 and you don’t want the admin of a limited company
The assignment rate is high enough that the deductions are proportionate
You value simplicity over tax efficiency
You want employment rights (holiday pay, sick pay, pension) that you wouldn’t get as a sole trader

Umbrella working makes less sense when:

The day rate is low — as one Reddit commenter noted, below around £400/day, the combination of employer’s NI, margin, and other costs erodes your take-home to the point where standard employment (with the same take-home but better benefits) may be a better deal
You could work outside IR35 through your own limited company and keep significantly more of the rate
The margin is unusually high or charged as a percentage rather than a flat fee

For the Reddit poster at £20/hour (£800/week, roughly £160/day), the deductions take a significant chunk. After employer’s NI, Apprenticeship Levy, and margin, gross pay is £688.50 — and after tax and employee NI, take-home is around £550. That’s an effective deduction rate of about 31% from the assignment rate, before any pension contribution.

How to Check If You’re Being Paid Correctly

Get your Key Information Document from the agency. It should show the full breakdown: assignment rate, all deductions, and your minimum gross pay.
Compare the KID to your payslip. The deductions on your payslip should match what the KID promised. If employer’s NI is higher than expected, check whether the 15% rate is being applied correctly (it should be on earnings above £96/week, the 2025/26 secondary threshold).
Check that employer’s NI is shown above gross pay, not as a deduction from it. If it’s listed below gross pay alongside Income Tax and employee NI, that’s a payslip presentation error — challenge it.
Verify your National Minimum Wage compliance. After all deductions (including the umbrella margin), your take-home pay must not fall below NMW/NLW for your age group. For a 21+ year-old working 40 hours in 2025/26, the National Living Wage is £12.21/hour — so take-home must be at least £488.40/week. If it’s lower, the umbrella is breaking the law.
Check your holiday pay. If you’re on “rolled up” holiday pay, it should appear as a separate line item (typically 12.07% of your pay) — not bundled into your gross pay without being identified. If you don’t see it, ask the umbrella how your holiday pay is being handled.
Use HMRC’s CEST tool if you’re unsure whether you should be inside or outside IR35. The Check Employment Status for Tax tool gives HMRC’s view based on your working arrangements. If your role is actually outside IR35, you could work through your own limited company and keep significantly more of the rate.

The Bottom Line

The assignment rate is not your wage. It’s what the agency pays the umbrella company. Your gross pay is the assignment rate minus employer’s NI, Apprenticeship Levy, the umbrella’s margin, and any employer pension contribution.
The deductions are legitimate, not a scam. Employer’s NI (15%), the Apprenticeship Levy (0.5%), and the umbrella margin are real employment costs that must be funded from the assignment rate. The umbrella is your employer and must pay these to HMRC.
You DO have employment rights. As an employee of the umbrella, you’re entitled to paid holiday (5.6 weeks/year), Statutory Sick Pay, National Minimum Wage, and auto-enrolment into a workplace pension. Anyone who tells you otherwise is wrong.
The real issue is transparency. Agencies should — and legally must — provide a Key Information Document showing the full breakdown before you sign up. If you didn’t get one, request it.
Check your payslip for the employer’s NI placement. It should appear above gross pay (as an employment cost), not below it as a deduction from gross pay. If it’s in the wrong place, your gross pay figure may be incorrect.
At lower rates, umbrella working may not be worth it. Below around £400/day, the combined deductions can erode your take-home to the point where standard employment — with the same or better take-home plus better benefits — may be a better deal. Run the numbers before committing.

Frequently Asked Questions

Why does my umbrella company deduct employer's National Insurance from my pay?

Because the rate you were quoted (the assignment rate) is what the agency pays the umbrella company, not your wage. The umbrella is your employer and must pay employer's NI to HMRC. Since the umbrella's only income is the assignment rate minus its margin, the employer's NI comes out of that rate before your gross pay is calculated. It's not deducted from your gross pay — it reduces what your gross pay is set at in the first place.

Is my umbrella company scamming me by charging employer's NI?

No. This is how all umbrella companies operate. The assignment rate covers the full cost of employing you — employer's NI, Apprenticeship Levy, pension contributions, holiday pay, and the umbrella's margin. Your gross pay is what's left after those employment costs are met. The confusion arises because agencies often advertise the assignment rate as if it were your wage. Check your Key Information Document for the full breakdown.

What is the assignment rate vs gross pay?

The assignment rate is the hourly or daily rate the agency pays the umbrella company for your work. Gross pay is your taxable salary — the assignment rate minus employer's NI, Apprenticeship Levy, the umbrella's margin, and any employer pension contribution. Your Income Tax and employee NI are then deducted from gross pay to give your net take-home pay. On a £400 day rate, gross pay might be around £340 after employment costs are deducted.

Do umbrella company workers get holiday pay and sick pay?

Yes. As an employee of the umbrella company, you have the same employment rights as any other employee — including paid holiday (at least 5.6 weeks/year), Statutory Sick Pay, and auto-enrolment into a workplace pension. Some umbrellas pay 'rolled up' holiday pay (an extra amount in each payslip); others pay it when you take leave. One commenter on a Reddit thread incorrectly claimed umbrella workers get no holiday pay or employment rights — this is wrong.

What is the Apprenticeship Levy and why is it on my payslip?

The Apprenticeship Levy is 0.5% of an employer's annual pay bill, payable by employers with a pay bill over £3 million. Large umbrella companies exceed this threshold, so they pay the levy. Since the levy is an employment cost funded from the assignment rate, it appears on your payslip as a deduction before gross pay is calculated. The £15,000 annual allowance means only employers with pay bills over £3m actually pay it.

How can I check if my umbrella company is paying me correctly?

Request your Key Information Document from the recruitment agency — it should show the assignment rate, all deductions, and your minimum gross pay. Compare it to your payslip. Employer's NI should appear above gross pay (as an employment cost), not below it as a deduction from gross pay. If employer's NI is listed alongside Income Tax and employee NI as a deduction from gross pay, that's a payslip presentation error worth challenging.
