How a SIPP Works

What Is a SIPP?

A Self-Invested Personal Pension (SIPP) is a personal pension that you control, choosing your own investments from a wide range of options.

Tax Relief

Your Tax Rate You Pay Government Adds In Your SIPP
Basic (20%) £80 £20 £100
Higher (40%) £60* £40 £100
Additional (45%) £55* £45 £100

After claiming additional relief via Self Assessment

How it works:

  1. Basic rate relief added automatically (£80 becomes £100)
  2. Higher/additional rate relief claimed via tax return

Annual Limits

Limit Amount
Standard annual allowance £60,000
Maximum contribution 100% of earnings
Carry forward Up to 3 years unused allowance
Money Purchase Annual Allowance £10,000 (if already drawing pension)

Access Rules

Age Access
Under 55 No access (except ill-health)
55-56 Access available currently
From April 2028 Access from 57

What You Can Take

  • 25% tax-free — lump sum or in stages
  • 75% taxable — taxed as income when withdrawn

SIPP Advantages

  1. Higher contribution limits (£60,000 vs £4,000)
  2. Better tax relief for higher earners (40-45%)
  3. Employer contributions possible
  4. Earlier access (55/57 vs 60)
  5. Usually outside inheritance tax
  6. Greater investment choice
  7. Can consolidate other pensions

SIPP Disadvantages

  1. 75% taxable on withdrawal
  2. Complex tax relief claiming for higher rates
  3. Money locked longer (vs LISA retirement access at 60)
  4. No use for first home purchase

When to Choose SIPP

SIPP is Usually Better If:

Situation Why SIPP
Higher/additional rate taxpayer 40-45% relief vs 25% bonus
Want to contribute more than £4,000/year SIPP allows £60,000
Have employer contributions SIPPs receive these, LISAs don’t
Want access before 60 SIPP from 55/57
Inheritance tax planning SIPPs usually outside estate
Over 40 Can’t open new LISA
Over 50 Can’t contribute to LISA
Consolidating existing pensions Can transfer into SIPP

SIPP Best For:

  • Maximum retirement savings capacity
  • Higher earners
  • Those with employer contributions
  • Earlier retirement (55/57 access)
  • Estate planning

When to Choose LISA

LISA is Usually Better If:

Situation Why LISA
Basic rate taxpayer Same effective relief, tax-free withdrawals
Saving for first home 25% bonus for property purchase
Want tax-free retirement income No tax on LISA withdrawals
Small regular contributions £4,000 limit is fine
Under 40 and starting out Open early, maximise bonus period
Want simpler system No tax return needed
Planning to retire at 60-65 LISA access at 60

LISA Best For:

  • First-time home buyers
  • Basic rate taxpayers
  • Those wanting tax-free retirement income
  • Supplementing workplace pension
  • Younger savers (more years of bonus)

Using Both: The Optimal Strategy

For many people, using both SIPP and LISA is optimal:

Combined Strategy

Priority Action Why
1st Workplace pension (employer match) Free money
2nd LISA (if buying first home) 25% bonus for deposit
3rd SIPP (additional contributions) Higher tax relief
4th LISA (if space remaining) Tax-free retirement

Sample Allocation: Basic Rate, First-Time Buyer

Pot Annual Contribution Benefit
Workplace pension £2,000 (+ employer £1,500) Employer match
Lifetime ISA £4,000 (+ £1,000 bonus) First home + retirement
SIPP Remaining capacity Additional retirement

Sample Allocation: Higher Rate, Already Own Home

Pot Annual Contribution Benefit
Workplace pension Maximise salary sacrifice 40% relief + NI saving
SIPP Additional contributions 40% tax relief
Stocks & Shares ISA Remaining savings Flexibility

Note: LISA less attractive after owning home for higher earners.

First Home vs Retirement

If You’re a First-Time Buyer

The LISA shines for its dual purpose:

Goal LISA Action
Buy first home Use bonus + contributions for deposit
Don’t buy by 60 Access for retirement tax-free
Buy, then continue Can keep contributing until 50 for retirement

Property rules:

  • Property value under £450,000
  • Must be your home (not second home or investment)
  • Must complete 12 months after opening LISA
  • Use through conveyancer

If You Already Own or Don’t Plan to Buy

LISA loses its first-home advantage:

Situation Better Choice
Higher rate taxpayer SIPP (better tax relief)
Basic rate taxpayer LISA still competitive (tax-free withdrawal)
Want earlier access SIPP (55/57 vs 60)

Age Considerations

Under 40

Action Reasoning
Open LISA now Must open before 40
Contribute at least £1 Starts 12-month clock for first home
Decide later Keep option open even if not using immediately

40-49

Situation Implication
Already have LISA Can continue contributing until 50
Don’t have LISA Cannot open new LISA

50+

Reality Implication
No new LISA contributions SIPP or ISA only
Existing LISA Can access at 60 or leave to grow

Common Scenarios

Scenario 1: 28-Year-Old Basic Rate, Saving for Home

Strategy Why
Maximise LISA (£4,000) 25% bonus for deposit
Workplace pension (employer match) Free money
Additional S&S ISA Flexibility

Best choice: LISA as priority alongside pension.

Scenario 2: 35-Year-Old Higher Rate, Has Home

Strategy Why
Maximise workplace pension 40% relief + employer contributions
Additional SIPP if space More 40% relief
S&S ISA Flexibility buffer

Best choice: SIPP for maximum tax relief.

Scenario 3: 25-Year-Old, Unsure About Home

Strategy Why
Open LISA with £1 Keeps option open
Wait on major contributions Decide when clearer
Focus on workplace pension Definite benefit

Best choice: Keep LISA option alive, focus on pension.

Scenario 4: 45-Year-Old, Catching Up

Strategy Why
Maximise SIPP contributions Higher limits, tax relief
Use carry forward May have unused allowances
Existing LISA Keep contributing until 50

Best choice: SIPP primary, LISA secondary.

Summary: Decision Framework

Your Situation Recommendation
Basic rate + first home goal LISA primary
Higher rate + any situation SIPP primary
Under 40, uncertain plans Open LISA + focus on pension
Over 40, no LISA SIPP + ISA
Want maximum savings Both (if eligible)
Want earlier access (55/57) SIPP
Want tax-free retirement income LISA

The Simple Rule

  1. Always get employer pension match first
  2. If basic rate: LISA is competitive
  3. If higher/additional rate: SIPP wins
  4. If buying first home: LISA is excellent
  5. If under 40: Open LISA even if not using immediately

Your Action Plan

If Choosing SIPP:

  1. Research low-cost providers (Vanguard, Fidelity, AJ Bell)
  2. Decide investment approach
  3. Set up regular contributions
  4. Remember to claim higher-rate relief

If Choosing LISA:

  1. Open before age 40
  2. Choose Cash or Stocks & Shares
  3. Contribute early in tax year for maximum bonus growth
  4. Understand the 25% withdrawal penalty

If Using Both:

  1. Prioritise employer-matched pension
  2. Maximise LISA (£4,000) if basic rate or buying home
  3. Top up SIPP with remaining capacity
  4. Review allocation annually
