The tax year ends on the 5th April 2025, so you need to make sure any money you want to put into your Lifetime ISA or Cash ISA is processed by then. The 5th April 2025 is a Saturday, so the last date you can transfer money into your Lifetime ISA or Cash ISA is before the 5th of April.
For example, with the Tembo Lifetime ISA or Cash ISA, you have until the 5th April 2025 to add money to your account as a one-off contribution in order for it to be processed by the tax year end.
If you’d rather add money to your Lifetime ISA via monthly direct debit, the 26th March 2025 is the last date you can set up a brand new direct debit, or edit the amount or change the date of an existing one. That’s because the last direct debit collection date for Lifetime ISAs for this tax year is the 1st April 2025.
If you want to add money to your Cash ISA via monthly direct debit, the 1st April 2025 is the last date you can set up a brand new direct debit, or edit the amount or change the date of an existing one. That’s because the last direct debit collection date for Cash ISAs for this tax year is the 4th April 2025.
Although the tax year doesn't technically end until the 5th April, these deadlines mean we can make sure we have time to process and log your ISA payments for this tax year. Any payments made after these deadlines won't be processed before tax year end.

Will my Direct Debit contribution count?
You must create a new direct debit into your Lifetime ISA, or edit an existing one by 26th March 2025 for the direct debit to be collected by 1st April 2025. Any Lifetime ISA direct debits collected after 26th March won't make the 2024/2025 tax year.
You must create a new direct debit into your Cash ISA, or edit an existing one by 1st April 2025 for the direct debit to be collected by 4th April 2025. Any Cash ISA direct debits collected after 1st April won't make the 2024/2025 tax year.
This is because changes to direct debits can only be made 3 or more working days before the collection date.
What happens if my Lifetime ISA bonus arrives after April 6th?
Your bonus takes 4-6 weeks to actually land in your account, but providing you made the contribution before the 5th April, it won't impact your 2025/2026 allowance. That's because the allowance is tied to the date the funds are paid in, not the date your bonus lands.
