It looks like Gordon has pulled off a masterstroke - addressed one of the major flaws in the tax credits system and at the same time given people a big incentive to increase pension savings!
The tax credits "income increase disregard" has increased massively from 2,500 to 25,000, which will eliminate most of the problems caused by tax credits always initially being assessed on last year's income
Together with the pension changes coming in April, where limits on tax relief for contributions to pension funds will go up to 100% of earnings, this could provide a nice little boost to get many people saving for their pensions.
Someone with 2 kids earning 25,000 or less, or 3+ kids and earning 30,000 or less, can now easily get 96% tax relief on pension contributions - simply by contributing in alternate years.
Say they contribute 10,000 to a pension fund/AVC/SIPP etc. They will get 22% tax relief on this, and their tax credits will increase by 37% of the 10,000.
If they then contribute *nothing* the next year, they will get the 37% increase in tax credits on the *same* 10,000 again next year, unless their gross income has increased by more than 15,000.
So a 10,000 payment into their pension has only cost them 400! Only problem is they will be temporarily out of pocket in the first year till they get the rest of the "relief" back in the second year, but if they've got 4000 knocking around in a savings account it could be a very good investment.
In some rarer situations, some people may even be able to get over 100% tax relief on pension contributions, so you can put money into a pension scheme but your take home pay could actually *increase* as a result! Eg if your employer operates a "salary sacrifice" scheme for pension contributions so you save NI as well, or if you've got several kids and/or childcare costs which could mean you are a higher rate taxpayer yet still entitled to more than just the family element of the CTC.
Can anyone spot a flaw in this?
