The Treasury has published details of next years tax rates and allowances for income tax and tax credit.
The 2011/2012 tax allowances carry bad news for higher rate taxpayers who are hit with lower thresholds for both the higher rate tax band - which is down from £37,400 to £35,000 - equivalent to an extra £480 per year in tax.
The upper earnings limit for class 1 and class 4 national insurance payments has reduced from £844 a week to £817 a week.
National Insurance rates have increased from 11% for lower earnings to 12%, and from 1% for upper earnings to 2%.
Better news for basic rate taxpayers however as the opposite has occurred as their allowances increase from £6,475 to £7,475 per year. The National Insurance primary threshold is now £139 - up from £110 last year.
