*Savings Rate Equivalent = the gross yield a fully-taxable savings account or bond would need to match this gilt's net yield, at that tax rate. Gilt coupons are taxed as income — at the rate in force when each is paid, which rises by 2 percentage points (to 22/42/47%) from 6 April 2027; the capital gain to par is exempt from CGT. Figures don't include your Personal Savings Allowance, so they're conservative. How we calculate this.
T30K is the UK Treasury gilt "4 5/8% Treasury Gilt 2030", paying a 4.625% annual coupon and redeeming at par (£100) on 22 May 2030 — about 3.6 years away. At its 15 Oct 2026 closing price of £99.00 the gross redemption yield is 4.931%. Trading below par, part of its return is a CGT-exempt capital gain to maturity (£100 per £10,000 nominal), so its net yield holds up better after tax than its coupon alone would suggest — a 45% taxpayer keeps 2.75% net. That is how gilt income is taxed in practice: gilt coupons are taxed as income, while the capital gain is free of capital gains tax on any disposal — at redemption or an earlier sale — though interest accrued since the last coupon is taxed as income when you sell.
