The W-9 tax form is an important tax form for any employer with freelance workers or an affiliate program. The full official name for this form is Form W-9: Request for Taxpayer Identification Number and Certification. The form is used for employers to collect the most important information from affiliates or freelance workers. These workers or affiliates get paid by the employer, but the worker is responsible for all his taxes. The W-9 form gets reported to the IRS to help keep track of the taxes that independent contractors actually owe.
The W-4 is a form from the Internal Revenue Service used by employers to determine the tax withholding for employees. The W-4 form features a worksheet to calculate the number of exemptions, or allowances, for federal tax purposes. Based on the number of allowances you claim, your employer will withhold a certain amount from each paycheck to satisfy your income tax liability. It’s essential to complete the W-4 form accurately to prevent under- or over-paying your federal taxes.
