The Starting rate band (SRB)
A starting rate applies to savings income up to a set band:
Year | From 2015/16 to 2020/21 | 2014/15 |
Rate | 0% | 10% |
Band | £5,000 | 2,880 |
The SRB is subject to a rather complicated rule.
The Personal Savings Allowance (PSA)
The PSA applies even if you do not qualify for the Savings Band.
From 2016/17 on the PSA exempts savings income within the allowance for basic and higher rate taxpayers.
