The Formula
Total Monthly = Your Contribution + Tax Relief + EmployerFrequently Asked Questions
What is a SIPP?
Self-Invested Personal Pension. A flexible pension where YOU choose investments (stocks, funds, bonds). Unlike workplace pensions, SIPPs give you full control. Popular providers: Vanguard, AJ Bell, Hargreaves Lansdown.
How does tax relief work?
Basic rate (20%): Contribute £100, government adds £25, total £125 in SIPP. Higher rate (40%): Contribute £100, get £25 automatic + claim £25 extra via tax return = £150 total. Additional rate (45%): Similar but £175 total.
SIPP vs Workplace Pension?
You can have BOTH! Workplace pension gets employer match (free money). SIPP gives investment control. Best strategy: Max workplace pension first (get all employer match), then top up with SIPP.
When can I access my SIPP?
Minimum age is 55 (rising to 57 in 2028). You can take 25% tax-free lump sum. Remaining 75% is taxed as income when withdrawn. No requirement to buy an annuity — you control withdrawals.
What's the annual allowance?
You can contribute up to £60,000/year (or 100% of earnings, whichever is lower) with tax relief. Includes your contributions + employer + tax relief. Tapered for high earners (£100K+ adjusted income).
