Easy-Access Cash ISAs Pay 4.68% Tax-Free — Here's How to Open One Before 5 April

Fixed-rate cash ISAs top out at around 4.32% for one-year fixes. Easy-access ISAs pay up to 4.68%. You read that correctly — you earn more AND keep full access to your money.

This inversion happens when providers expect Bank of England base rate cuts. The base rate sits at 3.75% after the December 2025 cut. Markets are pricing in further cuts through 2026. Fixed-rate providers have already baked those expected cuts into their pricing, which is why one-year fixes offer less than easy-access rates.

The risk with easy-access: your rate can drop at any time. If the BoE cuts to 3.5% or lower, providers will follow. But here's the calculation that matters — even if easy-access rates fall by 0.50% in six months, you'll still have earned more in total than locking into a 4.32% fix today.

Basic-rate taxpayers get a £1,000 personal savings allowance (PSA). Higher-rate taxpayers get £500. Additional-rate taxpayers get nothing. Once your savings interest exceeds your PSA, you pay income tax on the excess.

At 4.55% on a standard easy-access account, you'd breach the £1,000 basic-rate PSA with just £21,978 in savings. The £500 higher-rate PSA runs out at only £10,989.

Anything in a cash ISA earns interest completely outside the tax system. No PSA usage, no tax return complications, no worrying about which band you fall into. For anyone with savings above £20,000 — or planning to build savings over multiple tax years — using your annual ISA allowance is the single most valuable tax move available.

Higher-rate taxpayers saving the full £20,000 allowance at 4.68% earn £936 tax-free. The same amount in a taxable account at the same rate would yield £936 gross, but after 40% tax on the £436 above the PSA, you'd keep only £762. That's £174/year in tax saved — compounding year after year as your ISA balance grows.

Every provider's process follows the same pattern:

1. Choose a provider — compare rates on comparison sites. Look for the AER (annual equivalent rate), not the gross rate. Check whether the account is flexible (allows withdrawals and re-deposits without losing allowance)
2. Verify your identity — you'll need your National Insurance number, a UK address, and photo ID. Most providers do this digitally now
3. Fund the account — transfer from your bank account. Some providers accept as little as £1, others require a minimum opening deposit
4. Done — interest starts accruing immediately. Your £20,000 allowance is used the moment the deposit clears

The entire process takes 10-15 minutes with most online providers. Banks like Chip, Plum, and Trading 212 offer app-based ISAs that can be opened and funded within minutes. Traditional banks like Nationwide and Santander require slightly more setup but offer branch support.

One critical rule: you can only pay into one cash ISA per tax year (though the rules changed in April 2024 to allow multiple). Check whether your chosen provider offers a flexible ISA — this lets you withdraw and redeposit within the same tax year without using additional allowance.

On 6 April 2026, the 2025/26 tax year ends and your unused ISA allowance vanishes. You can't carry it forward, backdate contributions, or make up for it later.

If you've already used some of your allowance this year — perhaps putting £5,000 into a stocks and shares ISA in November — you still have £15,000 of cash ISA allowance remaining. The total across all ISA types cannot exceed £20,000.

Here's what catches people out:

• Transfers don't count as new contributions. Moving last year's cash ISA from one provider to another doesn't use this year's allowance. But you MUST use the official ISA transfer process — withdrawing and redepositing counts as a new contribution
• Processing times vary. Some providers take 3-5 working days to process a new ISA application. Opening on 3 April might not clear before the deadline
• Joint ISAs don't exist. ISAs are individual. A couple can shelter £40,000 between them by each using their full allowance

Easy-access ISAs aren't the only option. Here's how they stack up:

Notice accounts (30-120 days) pay up to 5.00% but lock your money during the notice period. If you have an emergency fund elsewhere and won't need this money for 3-4 months, the extra 0.30% is worth it. See our notice savings guide.

Regular savers pay up to 8.00% but cap monthly deposits at £200-£500. Excellent for building the habit of saving, but the headline rate is misleading — on average you only hold half the money for the full year, so effective returns are closer to 4%.

Fixed-rate ISAs guarantee your rate for 1-5 years. With the BoE base rate at 3.75% and expected to fall further, fixing looks less attractive than usual — easy-access rates are currently higher than most fixes.

The right answer for most people: put the bulk of your ISA allowance into easy-access at 4.68%, keep an eye on rates through the year, and transfer to a fix if easy-access rates drop below 4.00%.
