How do I transfer an ISA without losing its tax-free status?
To move an existing ISA to a new provider without losing its tax-free status, you must use the official ISA transfer process (requesting the transfer through the NEW provider, who then contacts your old provider directly), rather than withdrawing the money yourself and paying it into a new ISA -- withdrawing and redepositing loses the tax-free wrapper for that money and counts against your annual allowance again.
Full answer
ISA transfers let you move existing tax-free savings or investments between providers to get a better rate, wider investment choice, or improved service, without losing the tax-free status the money has already accumulated -- but only if done through the correct process. **Why you must use the formal transfer process** If you simply withdraw money from an existing ISA yourself and then pay it into a different ISA as a new deposit, that money loses its ISA tax-free wrapper status the moment it is withdrawn, and re-depositing it counts as using your CURRENT year's annual ISA allowance (potentially using up allowance you wanted for genuinely new savings) -- the formal transfer process avoids this entirely, moving the money directly between providers without it ever counting as a withdrawal or a new contribution. **How to initiate a transfer** You request the transfer through your NEW ISA provider (not your existing one) by completing their ISA transfer form, specifying the existing ISA you want to move -- the new provider then contacts your existing provider directly to arrange the transfer of funds, without the money passing through your own hands at any point. **Transferring previous years' ISA money versus current year money** You can transfer money paid into ISAs in PREVIOUS tax years either in full or in part, to as many different providers as you like, without it affecting your current year's ISA allowance -- but if you want to transfer money paid in during the CURRENT tax year, you generally must transfer the FULL amount paid in that year (not a partial amount), keeping it within the ISA system so it continues counting towards your allowance correctly. **Transfer timescales** Cash ISA transfers should typically complete within a set number of business days under industry guidelines, though transfers involving stocks and shares ISAs (where investments may need to be sold and repurchased, or transferred 'in specie' without selling) can take considerably longer -- if a transfer is taking noticeably longer than expected, you can raise this with either provider. **Worked example** Someone has £15,000 in a cash ISA from previous tax years, plus £5,000 paid in during the current tax year, with an existing provider offering an uncompetitive rate. They find a better rate elsewhere and complete the new provider's transfer form, requesting the full £20,000 to move across. Because it is handled as a formal transfer rather than a withdrawal and redeposit, none of it counts against their current year's ISA allowance, and the full amount retains its tax-free status throughout. **Practical tip** Always initiate an ISA move through the RECEIVING provider's official transfer process, never by withdrawing the money yourself first, since even an accidental withdrawal-and-redeposit (rather than a formal transfer) permanently loses that money's accumulated ISA tax-free status for anything beyond the current year's fresh allowance.
