SIPP Guide 2026/27: How £60,000 of Annual Tax Relief and Zero Lifetime Cap Changes Retirement Investing
A £10,000 pension contribution that costs you £5,500. That's the deal for an additional-rate taxpayer using a self-invested personal pension (SIPP) — the government adds the rest through tax relief. With the lifetime allowance abolished since April 2024 and the annual allowance holding at £60,000 for 2026/27, SIPPs remain the most generous tax shelter in UK personal finance. The arithmetic just got sharper. From April 2026, dividend tax rates jumped — basic rate from 8.75% to 10.75%, higher rate from 33.75% to 35.75%. For limited company directors who once favoured dividend extraction over pension contributions, the equation has tilted decisively toward the SIPP. A £60,000 employer contribution routed through a pension costs the company £60,000 gross. Taking the same £60,000 as dividends nets the director about £38,550 after corporation tax and dividend tax — a £21,450 gap that the SIPP swallows whole. This guide covers the 2026/27 rules, how SIPP fees differ between providers (they vary by more than £300/year on a £100,000 pot), and why the SIPP — not the ISA, not the LISA — is still the heavyweight champion of UK tax-efficient investing.
