— Understanding the result
A Transitional Tax-Free Amount Certificate (TTFAC) lets a member who crystallised pension benefits before 6 April 2024 replace the standard 25%-of-LTA-used deduction from their new lump-sum allowances with the tax-free cash actually taken. Where less was taken than the default assumes, it recovers allowance — but a certificate binds both ways, so it can also reduce it.
— How it's calculated
The transitional default
Members who crystallised benefits before 6 April 2024 have their new Lump Sum Allowance reduced by a default of 25% of the Lifetime Allowance percentage they used. That default assumes maximum tax-free cash was taken at every event — which is frequently untrue: defined-benefit members, members who took scheme pension without PCLS, and anyone who commuted less than the maximum all took less.

The certificate substitutes evidence
A Transitional Tax-Free Amount Certificate, applied for with scheme evidence of the tax-free amounts actually paid, substitutes the evidenced figure for the default — often recovering tens of thousands of pounds of allowance. Application timing depends on the event: member lump-sum entitlement and death-benefit payments have different deadlines. Confirm the applicable rule with the certification administrator; this comparison does not determine application eligibility.

When a certificate hurts
The certificate binds both ways. Where the member actually took MORE tax-free cash than the 25% default assumes — scheme-specific protected PCLS is the classic case — the evidenced deduction is larger than the default, and a certificate would reduce the remaining allowance. The engine compares both paths and flags this before you apply. On the LSDBA side, pre-75 serious ill-health and death-benefit events default to 100% of the LTA used, not 25%.

— How to work out whether a transitional tax-free amount certificate helps
Step 1
Find the default deduction
Calculate the standard transitional deduction: 25% of the Lifetime Allowance percentage used across the pre-6-April-2024 events.
Step 2
Gather the evidence
Collect scheme-administrator statements showing the tax-free amounts actually paid at each pre-2024 event.
Step 3
Compute the evidenced deduction
Total the actual tax-free cash taken — this is the figure a certificate substitutes for the default.
Step 4
Compare the two paths
A smaller evidenced figure than the default means a certificate recovers allowance; a larger one means a certificate would reduce it.
Step 5
Check the deadline
Confirm the applicable application deadline with the certification administrator. Member lump-sum entitlement and death-benefit payments have different timing rules; this comparison does not determine eligibility.
— Worked example
- Default LSA deduction (25% × LTA used)
- £214,620
- LSA remaining on the default
- £53,655
- Evidenced LSA deduction (actual TFC)
- £150,000
- LSA remaining with a TTFAC
- £118,275
- Uplift — allowance the certificate recovers
- £64,620
Computed live by the same engine the tool above runs. This example shows the evidenced path leaving more allowance than the default; it is not a recommendation to apply. Evidence of a higher actual TFC can flip the sign, and a certificate can bind even when it leaves less allowance.
— Frequently asked questions
What is a transitional tax-free amount certificate?
A TTFAC substitutes the tax-free amounts a member actually took before 6 April 2024 for the standard 25%-of-LTA-used default, when working out the new Lump Sum Allowance and Lump Sum and Death Benefit Allowance. It is applied for with scheme evidence.
Do I need a TTFAC?
A certificate can give a higher remaining allowance only where the member took less tax-free cash than the 25% default assumes — for example, defined-benefit members, members who took scheme pension without a lump sum, and anyone who commuted less than the maximum. This calculator compares the default and evidenced paths side by side.
When does a TTFAC make things worse?
The certificate binds both ways. Where the member actually took more tax-free cash than the 25% default assumes — scheme-specific protected PCLS is the classic case — the evidenced deduction is larger than the default, and a certificate would reduce the remaining allowance. The engine flags this before you apply.
What is the deadline to apply for a TTFAC?
Member lump-sum entitlement and death-benefit payments have different application deadlines (FA 2024 Sch 9 para 127(2), amended by SI 2024/1012). Confirm the applicable rule and dates with the certification administrator; this calculator does not determine whether an application can be made.
What evidence does a TTFAC need?
Evidence of the actual tax-free amounts paid at each pre-2024 event: scheme-administrator or BCE statements, financial records or bank statements. Without evidence an application will be refused and the default stands.
