The 2025/2026 tax year ends on 5 April 2026.

To make sure your contribution counts for this tax year, you need to add money to your Tembo Lifetime ISA before:

👉 9pm on Sunday 5 April 2026

Any contributions made after this time will count towards the 2026/2027 tax year instead.

If you contribute by monthly direct debit, the final collection date for this tax year is Wednesday 1 April 2026.

Direct debits must reach Tembo by this date, and it will take one working day to process, meaning the contribution will be applied to your LISA on Thursday 2 April 2026. The deadline falls slightly earlier this year as Friday 3 April is a bank holiday, which reduces the available processing days before the end of the tax year.

👉 You can amend the date or amount of your direct debit (or skip it) through the app up to 3 working days before the payment date. Direct debits can be skipped for up to 3 months at a time, or cancelled entirely - just make sure any changes are made before the 3 working day cut-off prior to the payment date.

Why is there a deadline?

Although the tax year officially ends at midnight on 5 April 2026, we set processing deadlines to make sure all ISA contributions are successfully received and logged within the correct tax year.

What happens if my LISA bonus arrives after 6 April?

Your Lifetime ISA bonus usually arrives 4–6 weeks after you make a contribution.

Don’t worry - this won’t affect your allowance.

As long as your contribution was made before the 5 April deadline, it will count towards your 2025/2026 Lifetime ISA allowance, even if the government bonus arrives later.
