How to Calculate Withholding Tax
Withholding tax is really an estimate of tax you owe, and you won’t know for sure how much you owe until you file your tax return. If too much tax is withheld, you will get a tax refund, but then you won’t have as much money in your paycheck to pay your expenses. On the other hand, if too little is withheld, you will owe tax, and that may be money you do not have readily available at the time you file.
Federal Income Tax Withholding
Finding the perfect balance may take a bit of trial and error, especially as your filing status and number of allowances may change from year to year. The IRS encourages everyone to use the IRS Tax Withholding Estimator to perform a quick “paycheck checkup” for federal income tax. The federal tax withholding estimator can help you estimate the right amount of federal taxes that should be withheld from your paycheck.

It is important to complete Form W-4 accurately so your employer withholds the right amount of tax from each paycheck.

Here are some things to remember as you complete your W-4VT:
Generally, dependents are children under 19 (or up to 24 if they are a full-time student) and any relatives who live with you and who you support financially.
If you and your spouse both claim your dependents on your respective W-4VTs, not enough income tax will be withheld, and you might end up with taxes due when you file. Only one spouse should claim the dependents.
If you entered an additional amount to be withheld on the federal W-4, consider entering 30% of that amount on Line 6.
If you have more than one employer, consider claiming zero allowances with the employer(s) where you earn less income.
If you qualify for the Vermont Child Tax Credit you may want to consider having less income withheld from your paycheck by claiming the maximum number of dependents.

Submit Completed Forms W-4 and W-4VT to Your Employer
Whenever an employee has income, an employer is required to withhold income tax. Once the employer has the information you’ve entered on forms W-4 and W-4VT, the employer will be able to calculate your withholding tax. To help employers calculate and withhold the right amount of tax, the IRS and the Vermont Department of Taxes issues guidance each year that include detailed instructions and withholding charts and tables. When you receive your pay—either by direct deposit or paper check—your employer has already deducted federal and state income taxes, as well as payroll taxes such as Social Security and Medicare.
