Only a handful of banks and building societies have launched new Isa accounts to encourage savers to use their cash Isa allowance of up to £15,240 before the end of this tax year on 6 April.
Any increases are small. AA Savings, where the deposit taker is Bank of Ireland, has raised the rate on its Easy Access Isa to 0.86% including a fixed rate bonus of 0.66% for the first year.
The top rate comes from Paragon Bank Limited Edition Easy Access Cash Isa at 1.05%.
Virgin Money Defined Access Isa pays 1.01% but limits you to making three withdrawals a year. Both accept transfers from other providers.
Fixed-rate and taxable deals
On taxable accounts the top one-year fixed rate bond comes from Atom Bank. To open an account savers must use an app on their phone or tablet. The next best deal is 1.61% from Secure Trust Bank available online.
On easy-access accounts internet-based French bank RCI pays a top 1.1% on its Freedom Account followed by Leeds Building Society Limited Edition Online Saver at 1.05%.
