What This Means for Your Tax Return
Money in a Lifetime ISA grows tax-free. You don't report interest, dividends or growth from it on your Self Assessment, and withdrawals aren't treated as income.
The flip side is that the withdrawal charge isn't a tax, so there's no relief for it. You can't claim it as a business expense or offset it against your profits.
Savings held outside an ISA work differently. Interest counts towards your Personal Savings Allowance (the amount of interest you can earn tax-free), which is £1,000 for basic rate taxpayers and £500 for higher rate taxpayers. Here's when you need to report bank interest on your tax return.
Why Self-Employed Savers Get Caught Out
Without an employer pension, many sole traders and freelancers use a Lifetime ISA as their retirement pot. The trouble is that self-employed income is rarely steady, so a quiet few months can make locked-away savings look very tempting.
The squeeze often comes around 31 January, when your balancing payment and first payment on account can land at the same time. A payment on account is an advance payment towards next year's tax bill, and it catches plenty of people out. Covering it from a Lifetime ISA means losing a quarter of whatever you withdraw.
Lifetime ISA or Pension?
Personal pension contributions work differently. Basic rate tax relief of 20% is added to what you pay in, and higher rate taxpayers can claim extra relief through their Self Assessment.
The Lifetime ISA bonus is a flat 25% whatever your tax band, but your contributions don't reduce your tax bill. If you're weighing them up, our guide to tax relief for the self-employed is a good starting point, and a regulated financial adviser can help with the decision itself.
