Business Rendition is an annual report of your companies’ assets. This report is required by the county where business is conducted. Check with your local counties for the deadlines. There is a county and school tax due on all of the company's assets and billed separately for fixed assets and vehicles. TYPICALLY the tax bill is received anywhere from late October to December; and is due by January 31st. Still, the tax payment is only deductible the year it is paid.

Payroll tax payments are required per payroll issued, monthly, or quarterly based on the total payroll and taxes due. (Note payroll taxes are payable per this schedule, even if the Form 944 is required.)
