Your tax code may change due to some of the following reasons:
The tax year for personal tax is from 6th April to 5th April. The standard personal allowance is £10,600 in 2015-16, which means that you don’t need to pay income tax until you earn more than £10,600. Your net tax allowances and reliefs (if you are eligible for any) are deducted from the personal allowance to arrive at your net allowance.
In most cases, your tax code will be your net allowance with the last digit replaced by L. The most common tax code in 2015-16 is 1060L – ie the personal allowance of £10,600. The personal allowance will increase to £10,800 for 2016/17 for most people so anyone with a tax code of 1060L at the moment will change to 1080L in April 2016.
Your employer / pension provider will reverse the process above to work out the tax free amount in your pay. A tax code of 1200L would indicate a tax free allowance of £12,000. If you are paid monthly your employer will divide the allowance by 12 and pay the first £1,000 tax free each month. HMRC notifies your employer of any change to your tax code, but if you don’t think you are on the right tax code contact HMRC or your employer to check. Your employer does not receive the reason for any adjustment to your tax code
Your tax free allowance is for you as an individual and not given to each employment / source of income. If your current employer uses the standard tax code (1060L for 2015-16) they will use up all your tax free allowance of £10,600. If you start a second part time job, you will have no tax free allowance left and your tax code will be different to 1060L.
