If you're a UK taxpayer it's always worth considering a Cash Isa, even though most people can now get some savings interest tax-free.
The personal savings allowance means basic rate taxpayers can earn £1,000 interest tax free without using their Isa, and people who pay the 40% rate can get £500. Read our round-up of the best savings rates to find out more.
But remember that wrapping your money in an Isa means you won't need to worry about a future tax bill because your savings pot has grown and you're earning more than the tax-free threshold.
Everyone aged over 16 can save up to £20,000 in an Isa during the 2017/18 tax year.
Unless otherwise specified, all these banks are individually licenced by the FCA, so your savings will be covered by the Financial Services Compensation Scheme (FSCS) up to £85,000. All interest rates are AER - the annual equivalent rate.
Each week we select our Moneywise Best Buys, highlighting the best Cash Isas on the market.
Top easy access Isas
When picking an Isa, the first thing to decide is whether you want to fix your interest rate or opt for more flexibility with a variable rate. If you want to make additional deposits beyond the upfront opening deposit, or make withdrawals, then a variable rate Isa with easy access is probably most suitable for you.

How are Moneywise Best Buys selected?
We look across as much of the market as possible to find the best deals using industry data from Defaqto.
All our picks are nationally available - online, by post or by phone. We try and pick products that are available to both new and existing customers, but we’ll highlight some offers for existing customers if they’re much better than what else is on offer.
Unless rates are significantly higher than on other accounts, we avoid products that pay an initial bonus (which is normally a euphemism for a rate cut after 12 months), or those with tiered rates (these may not pay the advertised interest rate if your balance rises above or falls below a set amount).
Deals only available to particular age groups or for “additional subscriptions” are also not included.
All these savings accounts are covered by the FSCS unless otherwise specified. We will prioritise deals from UK-based banks. If your bank is licenced by another European country, savings up to €100,000 will be protected, but by the government where the bank is headquartered, rather than the UK authorities.
We reserve the right to use our discretion at all times.
Hi Roger, the product was listed with incorrect name and link, but correct best-buy rate. The correct product is the Paragon Limited Edition Easy Access Cash Isa (Issue 7) with a rate of 1.45%. There is more information available on the product page:
Our apologies, the error has been corrected.
Ratesetter are a peer to peer lender which is much risker for savings than the Cash Isas we mention above. It is not protected by FSCS deposit insurance, and because the interest you earn comes from direct lending to business and individuals, the chance of losing your money is much higher.
