The two arrangements, in one table
| Net pay (the TPS) | Salary sacrifice | |
|---|---|---|
| Income tax saved | Yes — contributions deducted before tax | Yes — pay reduced before tax |
| National Insurance saved | No — NI charged on gross pay | Yes — NI charged on reduced pay |
| How it works | Scheme deducts contributions, then tax is calculated | You contractually exchange salary for benefit |
| Affects NI-based benefits | No | Can reduce State Pension and statutory payments |
What the difference costs you
Under salary sacrifice, the money going into your pension would not have been taxed for National Insurance either. Employee NI is 8% between £12,570 and £50,270, then 2% above. The forgone saving on your TPS contributions:
| Pay point | Your contribution | NI you pay on it | If it were salary sacrifice |
|---|---|---|---|
| M1 (£34,068) | £2,521 | £202 | £2,319 |
| M4 (£40,940) | £3,521 | £282 | £3,239 |
| M6 (£46,939) | £4,506 | £360 | £4,146 |
| U3 (£52,835) | £5,072 | £357 | £4,715 |
Note the U3 figure falls slightly despite the bigger contribution: pay above the £50,270 upper earnings limit only attracts 2% NI, so each pound above that line costs just 2p in NI. The take-home pay breakdown shows the full deduction stack.
Why the TPS cannot be salary sacrifice
Salary sacrifice requires you to contractually give up salary in exchange for a benefit. The Teachers' Pension is a statutory scheme: membership and contributions are set by regulations, not by your contract. Your employer cannot restructure your pay to convert TPS contributions into sacrifice, and the scheme rules fix the contribution basis. It is not an employer choice — it is how the legislation is built.
Where teachers DO get salary sacrifice
- Cycle to work schemes — common in schools, saves NI on the rental cost.
- Childcare via salary sacrifice — largely replaced by the tax-free childcare scheme, but legacy arrangements persist.
- Additional salary sacrifice AVCs — some trusts and local authorities offer AVC arrangements structured as sacrifice, which DO save NI on the voluntary contributions. Check with payroll; the AVC guide covers the mechanics.
- Electric vehicle schemes — increasingly offered by multi-academy trusts, with substantial NI savings on lease costs.
Does net pay affect your State Pension?
No. Because NI is charged on your full gross pay under net pay, your NI record builds exactly as if the pension did not exist. Under salary sacrifice, reduced gross pay would reduce NI credits and could weaken your State Pension entitlement and statutory payments like SMP. Net pay avoids that trap entirely — one genuine advantage of the arrangement.
The bottom line
The TPS gives you full income tax relief on contributions but no National Insurance relief, costing a typical classroom teacher £200-£360 a year versus a hypothetical sacrifice arrangement. It is a design feature of a statutory scheme, not a fault in your employer's payroll — and the contributions guide shows the complete deduction picture.
Frequently asked questions
Is the teachers' pension salary sacrifice?
No. The TPS operates a net-pay arrangement: contributions are deducted before income tax is calculated, but National Insurance is charged on your full gross pay. Salary sacrifice would save NI as well, which the statutory scheme does not do.
How much NI could I save if the teachers' pension were salary sacrifice?
Employee NI is 8% of contributions between £12,570 and £50,270 of pay, then 2% above. An M4 teacher paying £3,521 in contributions forgoes about £282 a year of NI relief; an M6 teacher about £360.
Why doesn't the teachers' pension save National Insurance?
Because it is a statutory scheme with contributions fixed by regulations, not a contractual benefit. Salary sacrifice requires you to contractually exchange salary for the benefit, which the scheme's legal structure does not permit.
Does paying into the teachers' pension affect my State Pension?
No — favourably, in fact. Because NI is charged on your full gross pay under net pay, your NI record and State Pension entitlement build exactly as if no pension deduction existed. Salary sacrifice arrangements can weaken NI-based entitlements.
Do teacher AVCs use salary sacrifice?
The standard Prudential AVC is net-pay like the main scheme, but some trusts and local authorities offer salary-sacrifice AVC arrangements that do save National Insurance. Ask your payroll which structure applies to you.
What salary sacrifice schemes can teachers use?
Commonly cycle to work, electric vehicle leases, and at some employers salary-sacrifice AVCs. Availability depends on your trust or local authority — payroll can confirm what is offered.
