State W-4 Form

Don’t Forget to Collect State W-4 Forms from New Hires

When you hire new employees, you need to collect information to verify employment eligibility and run payroll. Federal Forms W-4 and I-9 are just the beginning when it comes to new employee forms. You may also need to collect state-specific forms, including your state’s W-4. What is the state W-4 form?

What is a state W-4?

State W-4s work similarly to the federal Form W-4, Employee’s Withholding Allowance Certificate. Employees use state W-4s to claim withholding allowances from state income tax. States either use their own version of the state W-4 or the federal Form W-4. Unless your employees work in a state with no state income tax, they must fill out the W-4 state tax form before starting a new job.

Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming do not have state income tax. Most other states require employees to complete state Form W-4, unless the state imposes a flat income tax rate.

Your employees’ claims on the W-4 state form determine how much you will withhold from their wages for state income tax. Employees can claim allowances for themselves, a spouse, or child. The more allowances an employee claims on their state W-4, the less you will withhold.

Many states update their W-4 forms annually. Visit your state’s website to verify you are using the most up-to-date state W-4 form.

After collecting your employees’ completed state W-4 forms, use them to determine how much to withhold. Store employees’ state tax withholding forms in your records.

Federal vs. state Forms W-4

As an employer, you may need to withhold three types of income tax from employee wages, including federal, state, and local income taxes. You must distribute both federal and state Forms W-4 to employees so you can accurately run payroll. But, what’s the difference?

Employees claim withholding allowances from federal income tax on Form W-4. Employees use their state’s version of Form W-4 to claim withholding allowances from state income tax.

Updating state tax withholding forms

Your employees may want to adjust their withholding allowances on their state W-4 after completing the original form. For example, an employee may get married or divorced, add or remove a dependent, or go through another life event that affects their claims.

Employees can update their state tax withholding forms throughout the year. Be sure to collect their updated state tax forms for your records and adjust your payroll.

State withholding and Form W-2

Each year, you are responsible for reporting how much you paid employees and withheld from their wages for income and payroll taxes on Form W-2, Wage and Tax Statement.

Boxes 15-17 on Form W-2 deal with your state. Report how much you withheld and remitted for state income tax in Box 17. The amount you withheld for the year is based on the employee’s state W-4.

If your employees work in a state with state income tax, you need to collect state W-4 forms and store them in your records. Keep a copy in the cloud with Patriot’s online HR software. The HR software integrates with our online payroll software. Try both for free today!
