Frequently Asked Questions
How do I fill out a W-4 correctly?
The W-4 form requires your filing status, information about multiple jobs or working spouse, dependent credits, other adjustments, and any extra withholding. Use the IRS estimator tool or this calculator to ensure accurate withholding.
Should I claim 0 or 1 on my W-4?
The current W-4 form no longer uses allowances (0 or 1). Instead it uses a five-step process. Claiming fewer deductions results in more tax withheld, reducing the risk of owing at tax time.
