And expect penalties for the late filed 2019 form 1120S as well ... and if you were in business in 2020 then the payroll tax forms & the tax return are also very late ... get them completed ASAP.
And if you as the working owner of the S-Corp are not taking wages and issuing yourself a W-2 then you have bigger issues to tend to ... seek out a local tax pro to get you up to date and help you get out of the penalties that are piling up as I type.
And for the W-2 employees ... I hope you have been filing (and paying) the quarterly payroll returns and annual payroll returns along with the FUTA, SUTA and any other state forms that are needed. If not then you need to get help ASAP before they come looking for you.
