April 2021 Business Due Dates

April 15 - Household Employer Return Due 

If you paid cash wages of $2,200 or more in 2020 to a household employee, you must file Schedule H. If you are required to file a federal income tax return (Form 1040 or 1040-SR), file Schedule H with the return and report any household employment taxes. Report any federal unemployment (FUTA) tax on Schedule H if you paid total cash wages of $1,000 or more in any calendar quarter of 2019 or 2020 to household employees. Also, report any income tax that was withheld for your household employees. For more information, please call this office.

April 15 - Social Security, Medicare and Withheld Income Tax

If the monthly deposit rule applies, deposit the tax for payments in March.

April 15 - Non-Payroll Withholding 

If the monthly deposit rule applies, deposit the tax for payments in March.

April 15 - C-Corporations 

File a 2020 calendar year income tax return (Form 1120) and pay any tax due. If you need an automatic 6-month extension of time to file the return, file Form 7004, Application for Automatic Extension of Time to File Certain Business Income Tax, Information and Other Returns, and deposit what you estimate you owe. Filing this extension protects you from late filing penalties but not late payment penalties, so it is important that you estimate your liability and deposit it using the instructions on Form 7004.

The first installment of 2021 estimated tax of a calendar year corporation is due.
