The Salary Calculator

From April 2010, new tax rates will take effect. Most of us won’t be affected by the changes, as they only affect those with annual income in excess of £100,000.

The first change is the creation of a new income tax band for taxable income above £150,000, which will be taxed at a rate of 50%. This will make a significant difference to anyone who does earn this much as they currently are paying only 40% on this income.

The second change is a reduction of the personal allowance of £1 for every £2 your income is over £100,000. Your personal allowance is the amount you are allowed to earn without paying tax – by reducing this allowance the government are able to take more tax off your hands. In fact, I have calculated that whereas currently for every extra £2 you earn over £100,000 you take home £1.20, those of you lucky enough to be in this pay bracket will be taking home only £0.80 of that £2 from April 2010.

The Salary Calculator will be updated with these new rates early in 2010 when the details of personal allowances and other thresholds for that tax year are made available.
