Tax and Business Forms You'll Need to Start a Small Business

All businesses except partnerships must file an annual income tax return (partnerships file an information return). The form you use depends on how your business is organized. You must pay taxes as you go — as you earn or receive income during the year. Typically, a business pays estimated taxes quarterly to the federal and state government.

All U.S. employers must complete and retain a Form I-9 for each individual they hire for employment in the United States. This includes citizens and noncitizens. On the form, the employer must examine the employment eligibility and identity document(s) an employee presents to determine whether the document(s) reasonably appear to be genuine and relate to the individual and record the document information on the Form I-9. The list of acceptable documents can be found on the last page of the form.

Do not file Form I-9 with U.S. Immigrations and Customs Enforcement (ICE) or USCIS. Form I-9 must be kept by the employer either for three years after the date of hire or for one year after employment is terminated, whichever is later. The form must be available for inspection by authorized U.S. Government officials (Department of Homeland Security, Department of Labor, Department of Justice).
