What is a example of a withholding you might see on your pay stub?

This is called the withholding tax or income tax. Every employee has to pay tax for every income made which is directly credited by the employer for the government. Withheld tax within the year is reflected in the Income tax return alongside with other income and assets where then you can apply for exceptions or discounts. If withheld tax is over the supposed tax then it will be refunded.
