SIPP vs LISA — Which Should You Choose for Retirement?

SIPPs and Lifetime ISAs both help you save for retirement with tax benefits. Here’s how to choose between them.

Quick Comparison

Feature	SIPP	Lifetime ISA
Annual limit	£60,000	£4,000
Tax benefit	Tax relief (20-45%)	25% government bonus
Access age	55 (57 from 2028)	60
Early withdrawal	Tax on full amount, no penalty	25% penalty
First home use	No	Yes (up to £450,000 property)
Age to open	Any	18-39

How SIPP Tax Relief Works

You receive income tax relief on pension contributions:

Your Tax Rate	You Pay	Tax Relief	Total in SIPP
Basic (20%)	£80	£20	£100
Higher (40%)	£60	£40	£100
Additional (45%)	£55	£45	£100

Basic rate relief (20%) is added automatically. Higher/additional rate relief is claimed via Self Assessment.

Employer Contributions

If your employer contributes to your SIPP:

• No personal tax on the contribution
• Corporation Tax deduction for employer
• Doesn’t count against your earnings limit

How LISA Bonus Works

Your Contribution	Government Bonus	Total in LISA
£1,000	£250	£1,250
£2,000	£500	£2,500
£4,000	£1,000	£5,000

The 25% bonus is the same regardless of your tax rate.

Property Purchase Option

A major LISA advantage: you can use it for your first home.

You cannot use SIPP funds to buy your personal residence. Commercial property is allowed within some SIPPs, but not residential property for personal use.

When to Choose a SIPP

Situation	Why SIPP
Higher/additional rate taxpayer	Better tax relief
Want to save more than £4,000/year	Higher limit
Employer contributions	Can add to SIPP
Already own a home	LISA home benefit irrelevant
Over 39	Can’t open new LISA

When to Choose a LISA

Situation	Why LISA
Basic rate taxpayer	25% bonus beats 20% relief
Want to buy first home	Can use for property
Under 40	Can still open one
Want earlier access	60 vs 57 for SIPP
Simple, predictable bonus	25% regardless of circumstances

Using Both SIPP and LISA

Nothing stops you contributing to both:

Strategy	Approach
Maximise both	£4,000 LISA + SIPP contributions
House or retirement	LISA for flexibility, SIPP for pension
Different pots	Diversify tax treatment

Example: Higher Rate Taxpayer Strategy

Account	Contribution	Benefit
LISA	£4,000	£1,000 bonus (keep flexibility)
SIPP	£16,000	£8,000 tax relief (40%)
Total invested	£20,000 actual	£29,000 pot value

Investment Options

Retirement Income Comparison

At Retirement: SIPP

What Happens	Tax Treatment
25% tax-free lump sum	No tax
Remaining 75%	Taxed as income
Drawdown or annuity	Your choice

At Retirement: LISA

What Happens	Tax Treatment
Full amount available	Completely tax-free
No forced pension rules	Take as you wish
No lifetime allowance	Separate from pension

LISA money at 60+ is completely tax-free, which can be valuable for retirement income planning.

Death Benefits

SIPP on Death

Your Age at Death	Beneficiary Tax
Under 75	Tax-free to beneficiaries
75+	Taxed at beneficiary’s income rate

LISA on Death

Situation	What Happens
Dies	Passes to estate or named beneficiary
No penalty	Bonus kept, no 25% charge
Inheritance tax	May apply depending on estate size

Summary: Decision Guide

If You Are…	Consider
Basic rate taxpayer under 40	LISA first, then SIPP
Higher/additional rate taxpayer	SIPP for tax relief
Might buy first home	LISA for flexibility
Want maximum pension savings	SIPP (higher limits)
Have employer contributions	SIPP
Over 39	SIPP only (can’t open new LISA)

For many young savers, both accounts make sense: LISA for the first £4,000 (especially if homeownership is possible), SIPP for additional retirement savings (especially if higher rate taxpayer).
