Firstly, just want to confirm that the effective 60% tax bracket where your personal allowance is eroded starts next tax year, not this tax year?
Also, if you make pension contributions into a SIPP sufficient to keep your taxable income below 100K, will that avoid having to pay this band of tax? I've found an article in the Times that talks about using salary sacrifice to do this but I'm not sure about just making pension contributions.
Assuming that using a pension can avoid this tax bracket, presumably there is no problem with making a lump sum payment right at the end of the tax year when you have a much better idea of your taxable income for the tax year? (I'd assume this is ok but I wouldn't be completely surprised if there's some regulation somewhere that says lump sum payments made into a pension in March are treated specially)
Thanks,
Tim.
