Where should the next pound go?

Capture the match first, then salary sacrifice up to the annual allowance, then LISA if you qualify, then carry-forward if you have it, then ISA overflow. The order matters.

Step 1: Capture employer match
-
Already capturing match or no match offered.
Step 2: Salary sacrifice
£20,000/yr
Salary sacrifice: save income tax + employee NI at marginal; employer NI rebate funnels into the pension.
Step 3: LISA
-
No room in the budget after pension steps.
Step 4: Carry-forward
-
Skipped: no carry-forward available.
Step 5: ISA / overflow
-
All capacity absorbed by tax-advantaged accounts.

Most of the contribution sits in ISA / taxable rather than tax-advantaged wrappers. Either capacity exceeds annual allowance + LISA + match, or one of the upstream steps isn't being used. Worth checking each step.

Frequently asked questions

Why is employer match always first?

Because it's a 100% return on the slice that captures it. A 1:1 match means every £1 you contribute up to the match cap becomes £2 in the pension. No other step in the waterfall has that immediate doubling, always capture the match before anything else.

What's the employer NI rebate?

When you salary sacrifice, your employer saves 15% NI on the sacrificed amount (above the £5k threshold). Some employers pass that saving into your pension as an extra contribution. The default model assumes 100% pass-through; check your scheme's documentation.

Carry-forward, how does that work?

You can use unused annual allowance from the last 3 tax years if you've fully used the current year's £60k. You must have been a member of a registered pension scheme in those prior years. For a high-bonus year, carry-forward can unlock £100k+ of extra tax-advantaged contribution.
