*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; 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.
TR63 is the UK Treasury gilt "4% Treasury Gilt 2063", paying a 4% annual coupon and redeeming at par (£100) on 22 October 2063 — about 37.1 years away. At its 11 Sep 2026 closing price of £71.95 the gross redemption yield is 5.862%. Trading below par, part of its return is a CGT-exempt capital gain to maturity (£2,805 per £10,000 nominal), so its net yield holds up better after tax than its coupon alone would suggest — a 45% taxpayer keeps 3.57% net. That is the tax treatment of gilts 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.
