If I started a corporation in 2018 but haven't filed taxes yet, how do I start?

At this point, you should probably consult with a local tax professional since the return is way past due regardless of the tax year selected (calendar or fiscal).

See https://taxexperts.naea.org/listing/service/corporations

For an S corporation see https://www.irs.gov/instructions/i1120s#en_US_2021_publink11515kd0e416

For a C corporation see https://www.irs.gov/instructions/i1120#en_US_2021_publink11455td0e807

What kind of business.  Really a corporation?  (S-corporation or C-corporation)?  Or was it a partnership, LLC, or sole proprietorship?  How many owners?

Has the business been engaged in ongoing business activities?  (Finding clients, performing services, obtaining customers, etc.?)  Or has it been inactive.

Does the business have revenue?
