Answer 1

You can use the following calculator to determine how much tax will be deducted from your paycheck:

Remember that the amount of income tax deducted depends on how you fill out Form W-4 that you give to your employer. It is something YOU control and not fixed by law. It is not the real amount of tax you owe. The real amount is calculated when you fill out your tax return at the end of the year, and depends on all of your income (interest, investments, other jobs, gambing winning, etc), and deductions (some expenses, like mortgage interest) and number of dependents, etc. When you fill out and file your tax return, you will get a refund if too much was deducted or you will pay more if not enough was deducted. If not enough was paid as an estimate for ALL your income by this withholding (and other estimated payments through the year), and the amount was substantial you may be subject to interest.
