By making an investment, your capital is at risk. The value of your Moneyfarm investment depends on market fluctuations outside of our control and you may get back less than you invest. Past performance is no indicator of future performance. The tax treatment of a Moneyfarm Stocks and Shares ISA and a Moneyfarm Pension depends on your individual circumstances and may be subject to change in the future. You should seek financial advice if you are unsure about investing.

Yes, withdrawing money is quick and easy from your Moneyfarm Cash ISA, with withdrawals into your Moneyfarm account paid in 1 working day. Just head to your Cash ISA in the Moneyfarm app to request the amount you want to withdraw from your ISA.
Please note that the Moneyfarm Cash ISA is a flexible ISA, which means you can withdraw and replace money within the same tax year without affecting your annual ISA allowance. However, to qualify for the standard interest rate, you’ll need to ensure you don’t make more than 3 withdrawals in a single year. If you withdraw more than 3 times in a year, the interest rate on your Cash ISA will drop to our standard rate.
A money market fund (MMF) is a type of fund that is trusted by banks, other financial institutions and large companies to keep their money safe and accessible, while giving them a return.
A qualifying money market fund (QMMF) is a type of money market fund that is approved to hold client money, for example Cash ISA savings. What makes it “qualifying” is that the QMMF must meet higher regulatory standards than other MMFs.
Yes. Our Cash ISA has a variable rate, which means the rate can go up or down according to market conditions (largely driven by any changes in the Bank of England base rate). If we have to make a change to the rate we offer in the future, we’ll let customers know as soon as possible.
Note that the rate for our Cash ISA can also drop to a lower rate if the balance for a customer’s new contributions falls below £500 or they make more than 3 withdrawals in a year.
