Yes, Premium Bonds are tax free in the sense that matters to most holders: every prize, from £25 up to the £1 million jackpot, is paid in full with no UK Income Tax or Capital Gains Tax owed.1NS&I. Paying Tax on Your Savings The bonds themselves, however, still count toward your estate for inheritance tax, and if you live outside the UK your country of residence may tax the winnings.
What the UK Exemption Actually Covers
Premium Bonds are issued by National Savings and Investments (NS&I), a state-owned savings bank backed by HM Treasury.2GOV.UK. NS&I Instead of paying interest, NS&I enters each £1 bond into a monthly prize draw.3National Savings and Investments. Premium Bonds Because the return comes from a draw rather than interest, the law treats it differently from ordinary savings income. NS&I confirms that prizes are free from both UK Income Tax and Capital Gains Tax.1NS&I. Paying Tax on Your Savings
You do not report prizes to HMRC. There is no Self-Assessment box for Premium Bond winnings, no declaration as income, and no effect on your tax bracket. Whether the prize is £25 or £1 million, it lands in your account in full.1NS&I. Paying Tax on Your Savings Unlike bank interest above the Personal Savings Allowance, dividends, or rental income, there is no paperwork.
How Prizes Sit Alongside the Personal Savings Allowance
The Personal Savings Allowance lets you earn a set amount of savings interest before paying tax: £1,000 for basic rate taxpayers, £500 for higher rate taxpayers, and nothing for additional rate taxpayers.4GOV.UK. Tax on Savings Interest – How Much Tax You Pay
Premium Bond prizes sit outside this system. They are already tax-free under their own rules and do not count toward your allowance.4GOV.UK. Tax on Savings Interest – How Much Tax You Pay Win £500 in prize draws over the year and your full Personal Savings Allowance remains intact for interest earned in ordinary accounts. For higher rate taxpayers working with only £500 of allowance, that separation is useful: holding some savings in Premium Bonds keeps more regular interest inside the tax-free zone.
Inheritance Tax Still Applies to the Bonds
The “tax-free” label refers to the prizes, not the underlying holding. When a bondholder dies, the bonds are added to the estate at face value. A £50,000 holding adds £50,000 to the estate total.
The inheritance tax nil-rate band is £325,000, frozen at that level through at least April 2030.5GOV.UK. Inheritance Tax Thresholds and Interest Rates Estates above that threshold are generally taxed at 40%. A residence nil-rate band of £175,000 is available where the home passes to direct descendants, provided the total estate is under £2 million, and married couples and civil partners can transfer unused allowances.
NS&I keeps the bonds in the monthly prize draw for up to 12 months after death, and any prizes won during that period are paid to the estate.6National Savings and Investments. What to Do if an NS&I Customer Has Died Those posthumous prizes remain free from Income Tax, but the bond value itself is still part of the taxable estate. Executors should include Premium Bonds when totalling the estate.
If You Live Outside the UK
The UK does not tax Premium Bond prizes at the source no matter where the holder lives. Move abroad and keep your bonds, and the UK side stays clean: no withholding, no HMRC reporting. The complication is at the other end. Your country of residence may treat prizes as taxable income, whether as gambling winnings or as foreign investment income, and rates vary widely. NS&I warns that some of its products may be liable for local tax depending on the country, and that local restrictions may prevent you from holding certain products at all.7National Savings and Investments. Saving With Us When Living Abroad You also need to keep a UK bank account to receive payments, since NS&I only transacts in Sterling through UK banks.
Extra Complications for US Persons
NS&I flags that, given US gaming and lottery laws, it may not be possible or practical to hold Premium Bonds while living in the United States.7National Savings and Investments. Saving With Us When Living Abroad US citizens, green card holders, and tax residents with foreign financial accounts exceeding $10,000 in aggregate value at any point in the year must file a Report of Foreign Bank and Financial Accounts (FBAR) with FinCEN, whether or not the account produces taxable income.8Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) A Premium Bond holding that never wins a prize still triggers the filing if the threshold is met.
US filers may also need to report Premium Bonds on Form 8938 (Statement of Specified Foreign Financial Assets) once total foreign assets exceed separate thresholds, starting at $50,000 for unmarried taxpayers living in the United States. Penalties for missed filings can be severe, so any US person considering Premium Bonds should get professional advice before buying or keeping them.
