Yes, the Moneyfarm Cash ISA is FSCS-protected up to £120,000 per eligible person, with cash held via qualifying money market funds managed by regulated institutions. However, because the rate is variable and linked to these funds, returns can change over time.

Moneyfarm Cash ISA Review: 3.69% AER Tax Free Savings

Account: Moneyfarm Cash ISA

Description: Moneyfarm’s Cash ISA offers a competitive introductory rate and flexible access to tax-free savings. With a boosted first-year return and daily interest, it aims to combine the simplicity of a savings account with the convenience of an investment platform. However, the headline rate comes with several conditions that savers should understand.

How the Moneyfarm Cash ISA Works

Moneyfarm’s Cash ISA allows savers to earn tax-free interest on cash savings, with a current introductory rate of 4.33% AER (variable) in the first year. After 12 months, the rate drops to 3.51% AER (variable).

Interest is calculated daily, and you can deposit up to the £20,000 annual ISA allowance each tax year. Moneyfarm also allows free ISA transfers, so existing Cash ISA balances can be moved into the account without affecting your annual allowance.

Unlike traditional bank savings accounts, Moneyfarm holds customer cash in Qualifying Money Market Funds (QMMFs). These funds invest in short-term, low-risk instruments and are designed to act like cash while generating interest. The rate paid on the account is linked to the yield of these funds, meaning it can change if market rates move.

The account also offers some flexibility, allowing withdrawals when needed without penalties.

What’s the Catch?

The 4.33% headline rate only lasts for the first 12 months, after which the account reverts to 3.51%.

To maintain the boosted rate, savers must keep at least £500 in the account and limit withdrawals to three per year. Exceeding this reduces the rate to the lower level.

Finally, because savings are held in money market funds rather than a bank deposit, returns are variable and can change depending on market conditions.
