Why the Chip Cash ISA

The Chip Cash ISA is fully flexible, allowing you to deposit up to £20,000 per tax year and withdraw when it suits you - without impacting your ISA allowance. With no tax on your interest earned, and easily managed in our award-winning app, it's the smarter way to grow your wealth.

Open in minutes

No forms, no fuss. All you need is an existing bank account and your National Insurance number.

Seamless experience

Open your Chip Cash ISA and deposit from £1 as often as you like. Manage everything in your Chip app.

Unlimited access

We don't limit your withdrawals or reduce your interest rate for accessing your money.

Instant cash ISA benefits

The Chip Cash ISA is a flexible ISA, which means you can withdraw and deposit (almost instantly) as many times as you like, without it affecting your annual £20,000 ISA allowance.

With other providers, withdrawn funds can lose that tax-free status and will be taken off your ISA allowance. To add to that, you may be limited to a few withdrawals a year, or face a reduction to your interest rate for accessing your money. But not with Chip.

Please note: If you transfer your full balance out of the Chip Cash ISA, you will no longer be able to redeposit or transfer funds, and your account will be closed.

What is the Personal Savings Allowance?

The Personal Savings Allowance is the amount of tax-free2 interest you're able to earn annually across all of your accounts (not including ISAs).

Basic rate taxpayers have a £1,000 interest per year limit.
Higher-rate taxpayers have a £500 interest per year limit.
Additional rate taxpayers have no tax-free interest allowance.

With a cash ISA, the interest earned on your savings isn’t subject to tax2, meaning you can potentially see a higher return compared to a regular savings account.

What’s the Bank of England base rate of interest?

The Bank of England Bank Rate, often simply referred to as the base rate, is the interest rate at which the Bank of England lends money to commercial banks. It serves as a benchmark for all other interest rates in the economy, influencing the rates that banks offer on their lending and savings products.

The Monetary Policy Committee (MPC), a group within the Bank of England, sets the base rate based on economic conditions, with the primary aim of managing inflation. MPC decisions are widely reported on and their meeting notes are a matter of public record. 

What is a Cash ISA?

A Cash ISA (Individual Savings Account) is a type of savings account available to residents in the United Kingdom. It allows individuals to earn interest without paying income tax on the interest earned. Cash ISAs are considered a tax-efficient way to save because any interest earned within the ISA is tax-free.

Chip does not provide tax advice. Tax treatment depends on individual circumstances and may be subject to change in the future.

What is a tracker rate?

The Chip Cash ISA has a tracker rate. This means the gross interest rate is variable and tracks at a fixed percentage below the current Bank of England base rate. The specific margin applied depends on the product terms you were eligible for when you opened the account. You can view this margin and all related details in the app and within the summary box here.

Basically, when the base rate moves up or down, your savings rate will move on the same day. This ensures it automatically stays competitive and in line with the wider market. Read more

What is the annual ISA allowance and when does it reset?

The annual ISA allowance is £20,000 across the four different types of ISAs available, this includes the Cash ISA.

For example, if you had £10,000 in your Chip Stocks and Shares ISA and £10,000 in a Chip Cash ISA, you would have reached your annual ISA limit. Your annual ISA allowance resets at midnight 5 April 2025.

After this point we are in a new tax year and your new £20,000 ISA allowance comes into effect.

What does a flexible ISA mean?

A flexible ISA allows individuals to withdraw money from their ISA accounts and then replace it within the same tax year without affecting their annual ISA allowance. Also, if you withdraw your money in our Cash ISA, you won’t receive any restrictions or penalties.

When is interest paid?

Interest is paid on the fourth working day of each month.
