What percent of federal taxes are taken out of a 2 week paycheck?

When you have your net take home paycheck in your hand you do NOT have any thing taken out of your net take home paycheck or withheld from your net take home paycheck.

You do not have a standard percentage tax deduction amount for this purpose of your employer to withhold all of the different taxes and other items that your employer is required to withhold from your gross pay.

The employer payroll department would be the only one that should be able to tell you how much they will be required to withhold from your GROSS salary, wages, etc. for all of the different taxes and other amounts that they are required to withhold from your gross pay before they issue you the NET take home paycheck.

I HAVE NO IDEA THE ABOVE MENTIONS NET PAY AS IT DOES - IT ISN'T RELEVANT TO YOUR QUESTION OF BASICALLY HOW ONE GETS FROM GROSS TO NET PAY. Obviously, net pay is after deductions/withholdings.

In the US there is no specific fixed amount or percent. Two people working at the same job, making the same wage may (an almost always do) have much different amounts required to be withheld. THE AMOUNT WITHHELD IS DETERMINED BY YOU...NOT YOUR EMPLOYER, THE IRS OR ANYONE ELSE.

It depends on many, many things...not the least of which is what you consider tax. Many people group all their withholdings as a type of tax, but many may not be. Workers Comp, Unemployment, even FICA are all really more an insurance payment than a withholding against an income tax.

The amount of tax withheld depends obviously o which state (or even city) your in, the amount of income your projected on earning over the year, (which helps determine your tax bracket and the percent that may be required), as well as your filing status, number of dependents and other deductions (like interest on a mortgage) or contributions to 401K, or medical and other benefits you selected, etc., etc.

All these things can be adjusted for your circumstances by properly and completely filling out (or changing) the Form W-4 all employers ask you to. The variations are so numerous that again, it is fair to say that it would be uncommon for 2 people, working at the same job making the same salary would have the same amount withheld.

There are even a number of different legal ways for the payroll provider to calculate the amount to withhold considering all the above...but overall they make only a small difference.

Remember, anything withheld is just being done as an estimated installment payment toward whatever tax, if any, you do ultimately owe. If too much is withheld, it is refunded. (Too little, and you could pay a penalty and interest charges). Again, adjusting your W-4 is the way to correct for any of these circumstances. Just follow the instructions and examples for that form and you should have a very close amount for what is needed withheld for your situation...if for any number of reasons including those above, the situation changes... you will need to change the W-4.
