Last year's top cash Isa rates have plummeted, so act now to make sure you're not losing out on hundreds of pounds.
It's not just the expected expiry of bonus rates that hard-pressed savers need to be wary of. Big-name brands, such as Marks & Spencer, are sneakily slashing standard rates too.
We looked at the top easy-access cash Isas from late last March and found the majority have cut their rates (see our Top Cash Isa Transfers guide for the current best rates of up to 2.5% easy access to move your cash).
The chief problem for savers is the ending of bonuses. Banks and building societies regularly use them to boost the rate for a short period, usually a year, after which the interest rate dives. While the bonus expiry date is usually made clear upfront, many may have forgotten about it a year on.
Helen Saxon, MoneySavingExpert.com money analyst, says: "Savings rate bonuses can guarantee a good rate for a year or more. But when the bonus ends, your savings are usually left earning a pitiful 0.5% or less. Diarise to shift your cash when a bonus ends, else you could miss out on £100s of tax-free cash."
See the table below for a full round-up of what last year's best buys are currently paying, assuming the account was opened a year ago.

Isa deadline – use it or lose it
