Frequently Asked Questions
What is a SIPP and how does it work?
A Self-Invested Personal Pension (SIPP) is a pension wrapper that gives you control over your investments. You choose what to invest in - shares, funds, ETFs, bonds, property (commercial), and cash. You get the same tax benefits as other pensions: tax relief on contributions and tax-free growth.
How much tax relief do I get on SIPP contributions?
You get tax relief at your marginal rate. Basic rate taxpayers get 20% relief (pay £80, SIPP becomes £100). Higher rate taxpayers effectively get 40% relief (pay £60 net cost for £100 in SIPP). Additional rate taxpayers get 45% relief. The basic rate portion is added automatically; claim the rest via Self Assessment.
What is the maximum I can contribute to a SIPP?
You can contribute up to £60,000 per year or 100% of your earnings (whichever is lower) and receive tax relief. You can also use unused allowance from the previous 3 years through 'carry forward'. Employer contributions count towards this limit too.
When can I access my SIPP?
You can access your SIPP from age 55 (rising to 57 in 2028). You can take 25% tax-free as a lump sum, then pay income tax on the rest. Options include drawdown (flexible withdrawals), annuity purchase, or taking it all as cash (with significant tax implications).
What are SIPP fees and charges?
SIPPs typically charge: platform fees (0.15%-0.45% annually), dealing fees (£0-£12 per trade), and fund fees (0.1%-1%+ depending on fund). DIY platforms are cheapest; full-service SIPPs cost more but offer guidance. Compare total costs including any exit fees.
