HMRC’s latest ISA bulletin provides details of the ISA subscription limits for 2011/12.
From 6 April 2011, they will be calculated by reference to the retail prices index (RPI) figure for the September before the start of the new tax year.
The RPI for September 2010 was 4.6%, so for 2011/12 the overall ISA subscription limit will be £10,680 of which up to £5,340 can be subscribed to a cash ISA.
