Workers are being urged to check their pay slips after new tax year and national insurance changes came into effect.
Finance guru Martin Lewis has told workers to make sure they've not been overcharged by the tax office. Tax codes are used by HMRC to determine how much tax you should pay each month.
Each code is made up of numbers and letters which represent how much a person should earn before being taxed. If you've had a pay slip since April 6, you can check now to see if you're on the right code.
