*Grossed-up = 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.
T30 is the UK Treasury gilt "4 3/8% Treasury Gilt 2030", paying a 4.375% annual coupon and redeeming at par (£100) on 7 March 2030 — about 3.7 years away. At its 8 Jun 2026 closing price of £99.82 the gross redemption yield is 4.431%. It trades close to par, so almost all of its return is taxable coupon income — a 45% taxpayer keeps 2.46% net.
