AVC Additional Voluntary Contributions UK 2026/27: Tax-Free Cash Strategy

Additional Voluntary Contributions (AVCs) are extra pension contributions you can make on top of your main employer pension scheme. The most powerful AVC type - the Shared Cost AVC (SCAVC) - converts pre-tax income into tax-free cash at retirement at unusually attractive rates. This guide covers AVC mechanics for 2026/27 and when AVC beats other tax-efficient saving routes.

What an AVC is

An AVC is an additional defined contribution (DC) money-purchase pension arrangement run alongside your main scheme. Two main types:

1. In-house AVC: arranged through your employer, typically with Prudential, Scottish Widows, or Standard Life as provider.
2. Free-standing AVC (FSAVC): arranged independently with any UK pension provider. Less common since the 2006 simplification.

For LGPS members specifically, the in-house option is called a Shared Cost AVC (SCAVC) and includes a unique tax + NI advantage from the employer-arranged structure.

How tax relief works on AVCs

AVCs receive full income tax relief at your marginal rate:

• Basic-rate taxpayer (20%): £100 contribution costs you £80 net.
• Higher-rate taxpayer (40%): £100 contribution costs you £60 net.
• Additional-rate taxpayer (45%): £100 contribution costs you £55 net.
• £100k-£125k Personal Allowance taper zone: £100 contribution can effectively cost you £38 net (62% effective relief).

Plus, depending on the AVC structure:

• Shared Cost AVC (SCAVC): also saves employee NI (8% above the Primary Threshold). This is the same NI saving as salary sacrifice into pension.
• Free-standing AVC (FSAVC): NI is saved only via Self Assessment claim if you're a higher-rate taxpayer (no NI saving at source).

The retirement strategy that makes AVC powerful

The single most powerful AVC use case: maxing out tax-free cash at retirement.

UK pension rules allow you to take 25% of your total pension scheme value as a tax-free Pension Commencement Lump Sum (PCLS) at retirement. The PCLS is capped at £268,275 (the Lump Sum Allowance - LSA).

Here's the trick: AVC contributions become part of your "total scheme value" for PCLS purposes. By contributing AVC pre-retirement, you increase your tax-free cash entitlement.

Worked example: LGPS member with £400,000 main scheme value at retirement.

PCLS available without AVC: £400,000 × 25% = £100,000 (tax-free)
Add £40,000 AVC contributions over 5 years:
  Total scheme value: £440,000
  PCLS available: £440,000 × 25% = £110,000
  
Effective benefit: the £40,000 AVC turns into £40,000 of tax-free cash
                   (you can take the AVC pot itself as the PCLS slice)

Net effect for higher-rate taxpayer: £40,000 cost gross, £24,000 net of tax (after 40% relief), recovered as £40,000 tax-free cash at retirement. A 67% effective return + the underlying pension growth.

When AVC beats SIPP

Both AVC and SIPP (Self-Invested Personal Pension) offer DC pension structures with marginal-rate tax relief. AVC wins when:

1. You're in LGPS or another scheme that allows in-house SCAVC with NI saving (8% advantage over SIPP).
2. Your employer matches AVC contributions (some employers extend their main-scheme matching to AVCs).
3. You want operational simplicity (one provider, single retirement decision).
4. You want investment options curated by your employer's pension committee (typically lower fund fees than retail SIPPs).

SIPP wins when:

1. You want maximum investment control (any UK fund, ETF, even individual shares).
2. You're not in an SCAVC-eligible scheme (most non-LGPS schemes don't have SCAVC mechanics).
3. You're considering portfolio consolidation (SIPPs can hold multiple legacy pensions).

For LGPS members specifically, SCAVC is almost always the right first choice.

When AVC beats salary sacrifice

For defined contribution main schemes, salary sacrifice into pension is generally simpler and equally tax-efficient.

For defined benefit main schemes (NHS, Teachers, Civil Service, LGPS), salary sacrifice into pension is typically not allowed because the employer contribution is already pre-tax. AVC fills that gap - it lets you contribute more than the standard scheme requires, with marginal-rate relief.

Common AVC strategies

Strategy 1 - 5-year run-up

Most powerful for those 5 years from retirement. Max out AVC contributions (up to your Annual Allowance) for 5 years. The AVC pot grows to maximise tax-free cash at retirement.

Strategy 2 - Bonus-only AVC

Some employers allow a one-off AVC contribution from your annual bonus. This converts what would be 40-62% taxed bonus into tax-free cash at retirement.

Strategy 3 - Maximum income redirection

For higher-rate taxpayers in their 50s who don't need the cash now, contributing all income above £50,270 to AVC saves 40% income tax + 8% NI = 48% combined. At retirement, that £100 can come out as £25 tax-free + £75 taxed at typically lower retirement rates.

Annual Allowance interaction

AVC contributions count toward your Annual Allowance (£60,000 in 2026/27). Combined with your main scheme accrual, exceeding the AA triggers an Annual Allowance Charge.

For senior public-sector members already maxing out via main-scheme accrual, AVC headroom may be limited. Use the pension Annual Allowance guide to calculate your specific position.

The Lump Sum Allowance (LSA)

Since April 2024, the Lifetime Allowance has been replaced by:

• Lump Sum Allowance (LSA): £268,275 - caps tax-free cash across all your pensions.
• Lump Sum and Death Benefit Allowance (LSDBA): £1,073,100 - caps tax-free death benefits.

If your AVC + main scheme combined exceed the LSA, the excess tax-free cash entitlement is lost. For high-net-worth members already approaching the LSA, AVC strategy needs careful sequencing.

How AVC shows on your payslip

A correctly-structured AVC payslip should show:

• Main scheme pension contribution (LGPS / NHS / Civil Service tier rate).
• AVC contribution as a separate line, deducted before income tax (net pay arrangement for Shared Cost AVC).
• Total pension as the sum of both.

If the AVC is not appearing as a tax deduction (i.e., it's after-tax), you may be on a Free-standing AVC (FSAVC) rather than an in-house AVC. The tax efficiency differs.

When to talk to a pension specialist

For routine AVC contributions within your main scheme's framework, no specialist advice is needed. A regulated pension adviser earns their fee when:

• You're considering substantial AVC contributions (£20,000+) and need AA + LSA coordination.
• You're approaching retirement and need to optimise the tax-free cash mechanics.
• You have multiple pensions and want consolidation strategy.
• You're considering AVC vs alternative investments (ISA, GIA, alternative wrappers).

Your in-house AVC provider (typically Prudential, Scottish Widows, or Standard Life) provides scheme-specific information. For broader pension strategy, an FCA-authorised pension adviser via the Money Helper Adviser Directory.
