The 60% tax trap – watch out for the taper of personal allowance
Claire Trott, Technical Connection
The taper of the personal allowance could come as a bit of a surprise – and the effective rate can be hard to stomach. What can you do about this?
The taper of the personal allowance could be seen to be a nice problem to have, as you are earning over £100,000. But it can come as a bit of a surprise to some, where they have a bonus late in the year of a sudden pay rise. But the effective rate of tax on earnings between £100,000 and £125,140 is 60% in England and Wales and 63% in Scotland, which is hard for many to stomach.
The taper is calculated on the clients adjusted net income that can easily be reduced by making pension contributions, either personally or via salary sacrifice. Pure employer contributions won’t reduce this calculation.
So, if income has been higher than expected, or a bonus at the end of the tax year will push an individual into this band, increasing pension contributions can effectively give them 60% tax relief, meaning a contribution of £10,000 would only cost them £4,000 to make.
Care needs to be taken with regards to the annual allowance to ensure that this is not exceeded, or the benefits will be diminished. It should also be noted that gifts to charities can also reduce the adjusted net income calculations so should also be factored in.
