Two UK government childcare-cost-support schemes exist in 2026: the legacy Childcare Vouchers scheme (closed to new joiners since October 2018, but existing members can stay) and the newer Tax-Free Childcare (TFC, open since April 2017). They're mutually exclusive - you can't use both. Choosing the wrong one costs an average household £600-£1,500 a year.
This guide explains both, gives the maths for each common household type, and tells you when (if ever) to switch.

How each scheme works
Childcare Vouchers (legacy, closed scheme)
Pre-October-2018 joiners can continue. Mechanism:
- Employer arranges salary sacrifice with a voucher provider (Computershare, Edenred, etc).
- You give up part of your gross salary (up to a monthly cap that depends on when you joined) and receive vouchers of equivalent value.
- Vouchers exempt from PAYE income tax AND from NI for the employee.
- Employer also saves their 15% Class 1A NIC.
- Vouchers can be used to pay any registered childcare provider (nursery, childminder, after-school club, holiday club).
Monthly caps for current voucher members:
| Joined before April 2011 | Monthly limit |
|---|---|
| All taxpayers | £243/month |
| Joined April 2011 onwards | Depends on tax band |
| Basic-rate (20%) | £243/month |
| Higher-rate (40%) | £124/month |
| Additional-rate (45%) | £110/month |
Tax-Free Childcare (current open scheme)
Open to new and existing applicants. Mechanism:
- Open an online TFC account (no employer involvement needed).
- For every £8 you put in, the government adds £2 (a 25% top-up).
- You pay registered childcare providers directly from the TFC account.
- Annual top-up cap: £2,000 per child (£500 per quarter), or £4,000 per child if disabled.
- Both parents can pay in.
Eligibility
Childcare Vouchers eligibility (existing members only)
- Must have been receiving vouchers via your employer's salary-sacrifice scheme on or before 4 October 2018.
- Must continue to receive at least one voucher every 12 months - break the chain and you can't return.
- Your employer must still operate a scheme (some have wound theirs down).
- One parent participating per family is fine; both can if both employers offer vouchers.
Tax-Free Childcare eligibility
You and your partner (if you have one) must each:
- Earn at least the National Living Wage × 16 hours/week (£12.21 × 16 = £195.36/week in 2026/27, ~£10,158/year).
- Earn less than £100,000 each.
- Not be in receipt of Universal Credit, Tax Credits, or Childcare Vouchers.
- The child must be under 12 (or under 17 if disabled).
The £100,000 limit is per parent. If one of you earns £101,000, neither qualifies - even though the other earns £20,000. This is one of the most-cited unfairnesses of the scheme.
The maths - when each one wins
Scenario 1 - single parent, basic-rate taxpayer, one child in nursery £900/month
TFC route:
Annual childcare cost: £10,800
TFC top-up (capped at £2,000): £2,000
Net cost to family: £8,800
Childcare Vouchers route (basic-rate, £243/month):
Vouchers received: £2,916
Tax saved (20%): £583
NI saved (8%): £233
Total annual saving: £816
Net cost to family: £9,984
Winner: TFC by £1,184/year.
Scenario 2 - couple, both higher-rate, two children, total childcare £24,000/year
TFC route:
Annual childcare cost: £24,000
TFC top-up (£2k per child × 2): £4,000
Net cost to family: £20,000
Childcare Vouchers route (one parent on vouchers, higher-rate £124/month):
Vouchers received: £1,488
Tax saved (40%): £595
NI saved (2%): £30
Total annual saving: £625
Net cost to family: £23,375
If BOTH parents on vouchers (both £124/month):
Combined annual saving: £1,250
Net cost to family: £22,750
Winner: TFC by £2,750-£3,375/year.
Scenario 3 - couple, one earner £105,000, other £30,000
This couple is NOT eligible for TFC because one earner exceeds £100,000.
TFC route: NOT AVAILABLE
Childcare Vouchers route:
If lower earner had vouchers in legacy scheme: £243/month
Annual saving (basic-rate): £816
If higher earner had vouchers in legacy scheme: £124/month
Annual saving (higher-rate): £625
Otherwise: £0 government support.
This is the single most painful childcare-policy gap in 2026. Couples just above £100k get no TFC and may have no vouchers either.
The fix at family level: pension contributions to bring one parent's income below £100,000. £5,000 of pension sacrifice that brings a £105,000 earner to £100,000 may unlock £4,000+ of TFC (£2,000 per child × 2). Net saving: £4,000 − cost of foregoing £5,000 immediate cash + £5,000 in pension = often a clear win, particularly because the pension contribution avoids 60% marginal rate (between £100k and £125,140).
This is a calculation worth doing every year if you're near the threshold.
Scenario 4 - childcare cost only £200/month per child
Annual childcare cost (one child): £2,400
TFC top-up: £600
Net cost: £1,800
Childcare Vouchers (basic-rate, £243/month max):
Used: £200/month
Annual saving: £56 tax + £19 NI = £75
Net cost: £2,325
Winner: TFC by £525/year.
The pattern: TFC almost always wins for new families. Childcare Vouchers can win in narrow cases - typically very high childcare bills with both parents on vouchers, or where the family income disqualifies them from TFC.
When to keep your existing voucher scheme
Stay on Childcare Vouchers if:
- You're disqualified from TFC (one earner > £100,000, or you're on Universal Credit / Tax Credits).
- You've calculated the maths AND vouchers wins for your specific situation (rare).
- Your childcare costs are very low AND the voucher tax saving is small but reliable.
- You may have multiple children in the future and want to preserve the option.
Switch to TFC if:
- You qualify for TFC AND you have moderate-to-high childcare costs AND TFC wins on the maths above (the typical case).
Once you switch, you cannot go back to vouchers. So model carefully.
Salary sacrifice considerations
Both schemes interact with other parts of your pay:
- Childcare Vouchers are a salary sacrifice - they reduce your taxable pay and your NIable pay. This affects mortgage affordability (lenders may use post-sacrifice gross), pension contributions (if pension is calculated on gross), and statutory pay (SMP, SPP, SSP, ShPP - all calculated on gross post-sacrifice).
- TFC is NOT a salary sacrifice - your gross stays the same. The government top-up happens at the TFC account, not in your payroll. Mortgage affordability and statutory pay are unaffected.
For mortgage applicants, this is sometimes a decisive factor. Switching from vouchers to TFC bumps your gross-for-mortgage-purposes - useful when affordability is tight.
How to apply
TFC
Apply at gov.uk/tax-free-childcare. The HMRC website asks for:
- Both parents' employment status.
- Both parents' earnings.
- Each child's date of birth and any disability adjustments.
Approval is usually instant. You can pay providers as soon as the account is funded.
Childcare Vouchers (only if already a member)
Through your employer's HR or directly with the voucher provider (Computershare, Edenred, Sodexo). If you let your scheme lapse for over 12 months, you cannot rejoin.
