Individuals. File a 2019 Form 1040 or Form 1040-SR and pay any tax due. If you want an automatic 6-month extension of time to file the return, file Form 4868 and pay what you estimate you owe in tax to avoid penalties and interest. For more information, see Form 4868. Then, file Form 1040 or Form 1040-SR by October 15.

Individuals. If you’re not paying your 2020 income tax through withholding (or won’t pay in enough tax during the year that way), pay

Household employers. If you paid cash wages of $2,100 or more in 2019 to a household employee, you must file Schedule H (Form 1040 or 1040–SR), Household Employment Taxes. If you’re required to file a federal income tax return (Form 1040 or Form 1040-SR), file Schedule H (Form 1040

Report any federal unemployment (FUTA) tax on Schedule H (Form 1040 or 1040-SR) if you paid total cash wages of $1,000 or more in any calendar quarter of 2018 or 2019 to household employees. Also, report any income tax you withheld for your household employees. For more information, see Pub. 926.

Corporations. File a 2019 calendar year income tax return (Form 1120) and pay any tax due. If you want an automatic 6-month extension of time to file the return, file Form 7004 and deposit what you estimate you owe in taxes.
