That depends on your income, filing status, and how you filled out your W-4. The easiest thing to do is use this IRS calculator.

For a single person with no dependents, the first $16,550 is covered by the standard deduction, so if your income is less than that (which is $318 per week), you would owe no income tax. If you are planning to claim dependents, your tax-free threshold is about $36,000 per year. If you are married and your spouse works, you have to use the W-4 calculator for both of you combined, and revised W-4s should be filed at the same time, so the withholding is coordinated.
