In the showdown between cash Individual Savings Accounts (ISAs) and other savings accounts, you need to find the right fit for your finances. But what’s the difference between the two? Let’s break it down in plain English, so you can make the right call for your cash.
What’s a savings account?
Picture this: a place for your hard-earned money, with the bonus of earning interest on the side. That’s a savings account for you.
Difference between cash ISAs and savings accounts
Cash ISAs have a superpower – they can build interest tax-free! Yep, that’s right. While other savings accounts earn interest, cash ISAs take it up a notch.
You can earn tax-free interest on cash ISA savings up to the annual ISA allowance each tax year.
How about non-ISA savings accounts? Each tax year, the Personal Savings Allowance (PSA) allows basic rate taxpayers to earn up to £1,000 in interest before having to pay any tax, £500 for higher-rate taxpayers. Additional rate taxpayers pay tax on all interest they earn. Cash ISAs don’t count towards the allowance.
What’s an ISA?
Think of an ISA as the VIP section of the savings world with tax efficient benefits. There are different types of ISA: cash ISA, stocks and shares ISA, lifetime ISA, innovative finance ISA and junior ISA. Just a heads up, we only offer cash ISAs.
Benefits of a cash ISA
Let’s talk perks. With a cash ISA, say goodbye to handing over your hard-earned interest to the taxman. Plus, cash ISAs can offer choice, letting you tailor your savings game plan to suit your style.
Choosing a savings account
When it comes to picking the right savings account, it’s like shopping for the perfect pair of jeans - you want something that fits just right. Consider your goals, compare interest rates, and check out the perks each account offers. Whether you’re after easy access, or fixed rates of interest for a set period, there’s a savings account out there with your name on it.
How do ISAs work?
Each year you get an ISA allowance to put away money tax-free. For the 2026/2027 tax year that amount is £20,000 per year.
From 6 April 2027 there’s a change you need to know about. The ISA allowance remains at £20,000 but if you’re aged under 65, the amount you could save in a cash ISA will reduce to £12,000. But savers aged 65 and over aren’t affected – they’ll still be able to save their full £20,000 allowance in a cash ISA.
You can split your allowance across different types of ISAs. Each type of ISA caters to different financial needs and goals. Each type also has also has different rules and limits.
