Your income tax withholding is dependent on

Your income and number of dependents

Your income tax withholding is dependent on several factors including your income, filing status, number of allowances claimed on your Form W-4, and any additional withholding you request.

Here's a step-by-step guide on how to determine your income tax withholding:

1. Calculate your gross income: Start by calculating your total income for the year. This includes wages, salaries, tips, bonuses, self-employment income, rental income, and any other sources of income.

2. Determine your filing status: Your filing status can be single, married filing jointly, married filing separately, head of household, or qualifying widow(er) with dependent child. Your filing status affects your tax rates and standard deductions.

3. Calculate your allowances: Fill out a Form W-4 from your employer, which helps determine your allowance amount. More allowances generally result in less tax being withheld from your paycheck. The more accurately you complete this form, the closer your withholding will be to your actual tax liability.

4. Consider additional withholding: If you have other taxable income, such as interest, dividends, or capital gains, you may need to request additional withholding to cover your tax liability on those earnings.

5. Use the IRS withholding calculator: The IRS provides an online withholding calculator that allows you to input your income, deductions, and other relevant information to estimate your tax liability and recommend the appropriate withholding amount.

6. Consult tax tables: The IRS provides tax tables that correspond to different income levels and filing statuses. These tables help determine the amount of tax owed based on your income.

Remember, your income tax withholding is an estimate of your tax liability and may not exactly match your actual taxes due. It's important to review your withholding each year and adjust if necessary to avoid any surprises come tax time.
