This tax year, clarity is in short supply. Cut through the clutter with a flexible Stocks & Shares ISA designed for investors who know the difference.
Pay no platform or transfer fees to access over 200 expertly selected funds, including 30+ leading ETFs with refunded fund charges.
Capital is at risk. Investments can go down as well as up.
If you’ve taken a train, opened a newspaper or glanced at your phone today, you’ve probably seen an ISA ad – or five. Ours included. Millions are spent on marketing at this time of the year. But beyond the colour and slogans, what’s really on offer?
A Stocks & Shares Individual Savings Account (ISA) lets you invest your money in the stock market tax-free. Every tax year, you can invest up to £20,000 without paying capital gains or income tax on your earnings.
With a flexible ISA, you can take money out and put it back in the same tax year in the same ISA or any other ISA without using up your allowance, but only if the money was added this tax year.
Money from previous tax years (i.e. before 6 April 2025) can only be put back into the same ISA it was withdrawn from or must be formally transferred between providers to avoid affecting your annual limit.
The tax year ends on 5 April 2026. After that, your £20,000 ISA allowance resets and any unused portion expires. That’s why you see the annual rush.
If you plan to use this year’s allowance, Prosper’s flexible Stocks & Shares ISA takes just minutes to open.
Capital is at risk.
Pick from 200+ funds with zero platform, transfer, or exit fees. Invest up to £20,000 each tax year, free from UK income and capital gains tax.

As featured in
A Stocks & Shares ISA is a type of tax-efficient investment account offered by the UK government. It allows you to invest in things like shares, bonds and funds without paying tax on any capital gains or dividends.
Each tax year (6 April to 5 April), you can contribute up to £20,000 into ISAs. Any profits made within this limit are completely tax-free.
A Cash ISA (Individual Savings Account) is a savings account that allows you to earn interest on your money tax-free, meaning you don’t pay income tax on the interest you earn.
The ISA allowance is the amount the government lets you save or invest tax-free each tax year: currently £20,000.
This is a use-it-or-lose-it allowance. If you don’t use the full amount by 5 April, the unused portion doesn’t roll over to the next year.
The main difference is tax treatment. Interest earned in a Cash ISA is tax-free, while interest on a standard savings account may count towards your personal savings allowance.
The Prosper Cash ISA uses the same easy access savings product as the Prosper Simple Saver, which is powered by Griffin Bank Ltd and tracks the Bank of England base rate. The difference is that, within the ISA, any interest you earn is not subject to tax.
With a flexible ISA, you can take money out and put it back in the same tax year in the same ISA or any other ISA without using up your allowance, but only if the money was added this tax year.
Money from previous tax years (i.e. before 6 April 2025) can only be put back into the same ISA it was withdrawn from or must be formally transferred between providers to avoid affecting your annual limit.
To open a Prosper Cash ISA, you must:
• be a UK resident for tax purposes,
• be aged 18 or over and
• have a National Insurance number.
To be eligible to open a Stocks & Shares ISA, you must meet the following criteria:
• Be aged 18 or over
• Be a UK resident for tax purposes
Yes. Money in your Prosper Cash ISA is held with Griffin Bank Ltd (Firm Reference Number 970920) and is eligible for protection under the Financial Services Compensation Scheme (FSCS).
FSCS protection covers up to £120,000 per person, per authorised bank. Remember, if you have other deposits with the same bank or group, the protection applies to all eligible deposits up to £120,000.
For example, this limit applies across all eligible accounts you hold with Griffin Bank Ltd, including your Cash ISA, Prosper wallet and any other savings you may have with Griffin Bank.
You can have multiple ISAs (Cash, Stocks & Shares, Innovative Finance, Lifetime) at once, even of the same type from different providers, as long as you don't exceed the total annual £20,000 ISA allowance across all your accounts.
For example, if you invest £15,000 in a Stocks & Shares ISA, you’ll have £5,000 remaining to allocate to the same or another ISA that year.
A flexible ISA lets you withdraw money and put it back without using more of your ISA allowance. You can only replace up to the amount you withdrew, and only before the tax year ends.
No. At Prosper, we believe investing should be open to everyone, so there's no minimum deposit required to begin.
A Cash ISA works like a traditional savings account. Your money earns interest and is protected from losses. It is suitable for short-term savings (1–2 years).
In a Stocks & Shares ISA, your money is invested in the stock market, giving it the potential to grow more significantly over the long term (typically 5+ years). However, the value of your investments can go down as well as up.
No, Prosper doesn’t charge any platform, transfer, transaction or exit fees. We also refund fund management charges on 30+ ETFs from the likes of BlackRock, Vanguard and Fidelity, meaning more of your money stays invested and working for your future.
We retain the interest on uninvested cash and balances in the Prosper wallet. We do this unapologetically because it aligns our incentives with yours. We want your money invested and growing, not sitting idle.
We also charge for access to private market funds and take a share of the fees you pay for financial guidance. As we grow, we’ll continue to introduce new services with fair pricing, but the core experience stays low-cost and clear.
A Cash ISA works like a traditional savings account. Your money earns interest and is protected from losses, but the growth is typically modest. It is suitable for short-term savings (1–2 years).
In a Stocks & Shares ISA, your money is invested in the stock market, giving it the potential to grow more significantly over the long term (typically 5+ years). However, the value of your investments can go down as well as up.
