Real tax rate

Summary
If you make £12,638 a year living in United Kingdom, you will be taxed £90.07. That means that your net pay will be £12,548 per year, or £1,046 per month. Your average tax rate is 0.7% and your marginal tax rate is 14.1%. This marginal tax rate means that your immediate additional income will be taxed at this rate. For instance, an increase of £100 in your salary will be taxed £14.12, hence, your net pay will only increase by £85.88.
