George Osborne will announce a bank tax on Tuesday aiming to raise £3bn amid criticism the levy could hit UK competitivenesss.
The tax will be based on banks' balance sheets rather than their earnings, the Sunday Times reports.
"I'm going to ask the banks to pay a bank levy so there will be a contribution from them," he told the BBC. "What I'm determined to do is to make sure that the measures are tough but they're also fair."
Osborne will also proceed with a plan to rise CGT to around 40% for non-business assets but will soften his corporation tax proposals when he announces his Budget on Tuesday.

Lord Myners said a unilateral levy on the banking industry "would be a very heavy blow to the UK" and argued it could make British banks less competitive against international rivals.
