What happens to a Help to Buy ISA if I do not use it to buy a home?

Full answer

The Help to Buy ISA (now closed to new savers, since it was replaced by the Lifetime ISA for new applicants, though existing account holders can continue saving into one they already opened) has a specific, narrow mechanism for how its government bonus is actually paid, which catches out some savers who assume the bonus works like ordinary ISA interest. **How the Help to Buy ISA bonus works** Unlike a Lifetime ISA (where the 25% government bonus is added monthly directly into the ISA as savings build up), a Help to Buy ISA bonus is only calculated and paid out at the point of actually completing on a qualifying first home purchase -- your solicitor or conveyancer submits a claim for the bonus as part of the purchase completion process, and the bonus (25% of your total savings, up to a maximum bonus amount) is paid directly towards the purchase, not into your ISA account itself in advance. **What happens if you never buy a qualifying home** If your circumstances change and you never end up buying a qualifying first home (for example, you decide to keep renting long-term, or you're no longer a first-time buyer having already owned a home before), you simply keep whatever cash you have personally saved into the Help to Buy ISA -- this money remains genuinely yours and can be withdrawn or used for any purpose, but you will never receive the 25% government bonus, since that specific bonus is legally tied to completing a genuine qualifying home purchase and claiming it through the proper solicitor-led process. **Why some savers close their Help to Buy ISA into a Lifetime ISA instead** Because the Lifetime ISA offers a similar 25% government bonus but with a higher annual contribution limit (£4,000 a year, versus the Help to Buy ISA's lower monthly contribution limits) and a different bonus payment mechanism (monthly, directly into the account, rather than only at completion), some Help to Buy ISA holders have chosen to transfer their savings into a Lifetime ISA instead, which can still be done using the official ISA transfer process without losing the tax-free wrapper -- though savers should carefully check the specific transfer rules and eligibility criteria (including the LISA's own age restrictions on opening a new account) before doing so. **Property price cap differences** Help to Buy ISA bonuses can only be used towards home purchases up to a specific price cap (which varies between London and the rest of the UK), and using the bonus towards a home priced above this cap disqualifies the bonus claim entirely -- the Lifetime ISA has its own separate, and different, property price cap that applies UK-wide, so savers switching between the two schemes need to check which cap applies to their specific planned purchase. **Worked example** A saver opened a Help to Buy ISA several years ago and has built up £8,000 in savings, but has since decided to continue renting rather than buying a home in the near future. She can withdraw the full £8,000 at any time for any purpose, since this is simply her own saved cash -- but she will never receive the associated 25% government bonus (which would have been up to £2,000 based on the maximum bonus rules) unless she eventually does use the account towards a genuine qualifying first home purchase and has her solicitor formally claim the bonus as part of that specific transaction. **Practical tip** Help to Buy ISA holders who are uncertain whether they will buy a qualifying home in the foreseeable future should specifically check whether transferring to a Lifetime ISA (if still within the LISA's eligibility age) might offer a more flexible route to the government bonus, given the LISA's different bonus payment structure and broader (though not identical) list of situations in which the bonus can be accessed without penalty.
