Gilts For Savers: Tax, Pros, Cons And Risks Explained
If you're a higher or additional-rate taxpayer with savings outside an ISA, you may have noticed more people talking about gilts.
Gilts can be useful for some people, but they aren't a savings account and they have their own rules and risks. Here's how they work, how they're taxed, and the pros and cons – no tips and no predictions.
Remember: investing puts your capital at risk. The value of investments, including gilts sold before they mature, can fall as well as rise and you may get back less than you invest. Tax rules can change, and their effect depends on your individual circumstances.
First, The Basics: What Is A Gilt?
A gilt is a loan to the UK government, managed by the UK Debt Management Office (DMO) and traded on the London Stock Exchange (UK DMO: About gilts).
Nominal value: prices are quoted per £100 nominal – the amount repaid at the end, not necessarily what you pay.
Coupon: the fixed interest, paid every six months. A 1% gilt pays £1 a year per £100 nominal.
Redemption (maturity): the date the £100 nominal is repaid. "Short-dated" gilts have a few years or less to run.
Clean and dirty price: the quoted "clean" price excludes interest built up since the last coupon. You usually also pay this "accrued interest" to the seller, so the "dirty" price is what you actually pay (HMRC: HS343 Accrued Income Scheme).
Yield: the redemption yield is the return if you buy today and hold to maturity. When prices fall, yields rise, and vice versa (UK DMO).
Most gilts have a fixed coupon. "Index-linked" gilts adjust payments in line with the Retail Prices Index (RPI).
How Gilts Are Taxed
Coupon income is taxable. Gilt interest is savings income. It counts towards your Personal Savings Allowance: £1,000 for basic-rate taxpayers, £500 for higher-rate and £0 for additional-rate taxpayers (gov.uk: Tax on savings interest). It's normally paid without tax deducted and is reported as taxable UK interest (HMRC: SA101 notes 2026).
Gains are exempt from Capital Gains Tax (CGT). You don't pay CGT on gilts (gov.uk: Capital Gains Tax – what you pay it on; HMRC Capital Gains Manual CG54900). The flip side: losses can't be offset against other gains.
The Accrued Income Scheme: if your total nominal holdings exceed £5,000, accrued interest on buying or selling can be taxed or relieved as income (HMRC: SAIM4210).
In an ISA: stocks and shares ISAs can hold government bonds, with no tax on income or gains (gov.uk: How ISAs work), but it uses your £20,000 allowance. See our Cash ISAs guide too.
In a SIPP or other pension: the fund grows free of tax, but withdrawals beyond the tax-free lump sum (usually up to 25%) are taxed as income, and the money is locked away until minimum pension age (MoneyHelper: Tax-efficient ways to save or invest).
Why low-coupon, short-dated gilts? Gilts issued when rates were very low have small coupons, so they trade below £100. Held to maturity, most of the return is the rise back to £100, which isn't subject to CGT, and little is taxable interest. For higher and additional-rate taxpayers who've used their Personal Savings Allowance, that can mean less tax than on the same amount of savings interest. Inside an ISA or pension, everything is sheltered anyway, so the difference matters much less.
An Illustrative Example
Figures are made up to show how the tax works. They are not real prices, a forecast or a recommendation, and they ignore dealing costs and fees.
Imagine a 0.5% gilt with one year to run, bought at £96 per £100 nominal. Held to maturity, it pays £0.50 interest and repays £100: a £4.50 return, of which £0.50 is taxable. For a higher-rate taxpayer who's used their Personal Savings Allowance, tax would be £0.20. The same £4.50 earned as savings interest would mean £1.80 tax. Real prices and your tax position will differ.
The Advantages
UK government backing: the DMO notes the government has never failed to make a gilt payment when due – a strong record, but not a promise about the future.
A known return if held to maturity: the coupons and repayment are known in advance, so your return at the price paid is fixed if you hold to the end.
The CGT exemption: under current rules.
Liquidity: gilts can usually be sold before maturity, at the market price on the day.
The Disadvantages And Risks
The price can fall: if you sell before maturity, you may get back less than you paid.
Interest rate risk: if rates rise after you buy, prices tend to fall.
Inflation risk: fixed payments lose real value as prices rise.
Reinvestment risk: rates may be lower when your gilt matures.
No FSCS deposit protection: gilts aren't deposits. The risk is UK government default, and the FSCS doesn't cover falls in investment value (FSCS: Investments).
Costs: dealing and platform fees can eat into a short-dated gilt's return.
Complexity: comparing a redemption yield with a savings rate isn't simple once tax, accrued interest and costs are included.
Tax rules can change.
Not Sure Whether Gilts, Cash Or Something Else Suits You?
That's completely normal. Gilts are just one option, and spreading your money sensibly matters (see our diversification guide). The right mix depends on:
How much easy-access cash you need for emergencies
When you'll need the money, and whether you could hold to maturity
Your tax band, ISA allowance and pension options
How you feel about risk
Case Study: Helen's Review (Illustrative)
Names and details are illustrative.
Helen, 61, from Neston, is a higher-rate taxpayer with savings outside an ISA. She'd read about gilts but wasn't sure how they compared or whether she'd need the money early. With an Independent Financial Adviser (IFA), she agreed how much to keep in cash, then looked at her ISA, pension and timescales before deciding whether any of her savings might suit gilts or another option.
Key lessons:
Start with the bigger picture: what suits one person may not suit another.
Timing matters: gilts are most predictable held to maturity.
Every option has a trade-off: less tax can mean more price risk.
