What percentage should you deduct from from your paycheck?

You NEVER do have any deductions for federal taxes or other items from your net take home paycheck when it is issued to you.

You do NOT have any set percentage amount for this purpose.

You could have some other amounts beside the taxes that your employer payroll department would be required to calculate and withhold from your gross salary earnings before the payroll department would be able to issue you your net take home paychecks.

You should ask the payroll department for some numbers because they would be the only one that would know all of the different amounts that they will be required to withhold.

The amount of taxes that are withheld during this earning period is the same as estimated tax payments and if too much is withheld you will receive the over withheld amount back as a refund once your 2010 1040 federal and state income tax return is completely correctly and filed to the correct IRS address. If not enough federal and state income were withheld then you will end up owing some more taxes when the income tax returns are completed correctly and you will then have send the owed amounts with the income tax returns when they are filed in the year 2011.
