Taking money out of a Monzo ISA

Fixed Rate Cash ISA (1 year)

No access during the term. You can only close the whole Pot early and give up some of the interest earned (the app shows how much).

Fixed Rate Cash ISA (2 years)

No access during the term. You can only close the whole Pot early and give up some of the interest earned (the app shows how much).

Fixed Rate Cash ISA (3 years)

No access during the term. You can only close the whole Pot early and give up some of the interest earned (the app shows how much).

Select Access Cash ISA

Withdraw instantly any time; more than 2 withdrawals a year cuts the rate until the Pot's anniversary. Keep £500 or more in the Pot to keep it open.

Instant Access Cash ISA

Withdraw instantly any time with no limit. Flexible ISA, so money replaced in the same tax year doesn't use extra allowance.

Transferring an ISA to or from Monzo

None of Monzo's adult Cash ISAs accepts transfers in, so you can only pay in new money.

Transfers into Monzo

• Monzo does not currently accept transfers into its Cash ISAs, so an existing ISA cannot be moved into a Monzo Cash ISA.
• A Monzo current account is required to open a Monzo Cash ISA.

How long a transfer takes

gov.uk says ISA transfers should take no longer than 15 working days between Cash ISAs, and 30 calendar days for other types of transfer.

Moving an ISA away from Monzo

Monzo says it only supports full ISA transfers: transferring a Cash ISA moves and closes all of its Cash ISA Pots at once, while regular Savings Pots are not affected. Closing a Monzo Fixed Rate Cash ISA pot before the maturity date forfeits up to 25% of the total interest for the term, capped at the interest earned so far. That is equivalent to 90 days of interest on a 1 year term, 180 days on a 2 year term and 270 days on a 3 year term. You can move a Cash ISA from Monzo to another provider at any time. Ask the new provider to arrange the transfer: if you take the money out yourself, it leaves the ISA and paying it in again uses your allowance. A fixed rate ISA usually charges for leaving before the end of its term. See how ISA transfers work.

Is the Monzo ISA flexible?

All 5 of Monzo's adult Cash ISAs are flexible, so you can take money out and put it back in the same tax year without using more of your allowance.
