How do you fill out form w-4p so that they take out more federal taxes?

To ensure more federal taxes are withheld using Form W-4P, you can either claim fewer allowances or indicate an additional amount to be withheld. In Line 4, you can specify an extra withholding amount, which will increase your federal tax deduction. Additionally, if you choose "Married" or "Single" filing status, opting for "Single" may also result in higher withholding. Always review your specific tax situation or consult a tax professional for personalized advice.
