Can my boss withhold my money until i turn in the w-4 form?

Yes, your employer can withhold your pay if you haven't submitted a W-4 form, as they need it to determine the correct amount of federal income tax to withhold from your earnings. However, they are generally required to pay you for the hours worked, but the withholding may result in a higher percentage being taken out if no W-4 is provided. It's best to communicate with your employer to resolve the situation and ensure you receive your pay promptly.
