Okay, here's how to fill out Form W-4 to have extra tax withheld:
1. Personal Information (Steps 1a-1c):
* Step 1(a): Enter your first name and middle initial, and then your last name.
* Step 1(b): Enter your home address.
* Step 1(c): Enter your filing status. Choose Single, Married Filing Jointly, or Head of Household. This is important because it affects the standard deduction and tax brackets used to calculate your withholding.
2. Multiple Jobs or Spouse Works (Step 2):
* This step is crucial if you have more than one job or if you're married filing jointly and your spouse also works. If this applies to you, choose only one of the following options:
* (a) Use the Tax Withholding Estimator: This is the most accurate way to determine your withholding. The IRS provides an online tool to help you calculate the right amount.
* (b) Multiple Jobs Worksheet: You can use the worksheet on page 3 of Form W-4 to calculate the extra withholding needed.
* (c) Check the box: If there are only two jobs total (you and your spouse), you can simply check the box in Step 2(c). This will increase your withholding, but it might not be as accurate as the other methods.
3. Claim Dependents (Step 3):
* If your income is $200,000 or less (or $400,000 or less if married filing jointly), you can claim the child tax credit for each qualifying child under age 17.
* You can also claim a credit for other qualifying dependents, like an elderly parent you support.
* Enter the total amount of these credits in Step 3.
4. Other Adjustments (Step 4):
* Step 4(a): If you want to itemize deductions that are larger than the standard deduction, enter the estimated amount of these deductions here.
* Step 4(b): Enter any other income you expect to receive that is not subject to withholding (like self-employment income or investment income).
* Step 4(c): This is where you specify any additional amount you want withheld from each paycheck. If you want an extra $100 withheld per paycheck, enter $100 here.
5. Sign and Date (Step 5):
* Sign and date the form to certify that the information is correct.
6. Employer Information (Below Step 5):
* Your employer will complete this section with their information.
To increase your withholding, the most direct method is to fill out Step 4(c) with the additional amount you want withheld from each paycheck. If you have multiple jobs or your spouse works, use the IRS Tax Withholding Estimator for accuracy.
