Seconded. Filing the 1040 is straightforward compared to the 1120S, and the minimum taxes are real (my experience was NYS, with incorporation in NH for historical reasons). The 1040 instructions are maddening but nigh-complete. A thoughtful person with enough time on their hands has a prayer of figuring out even relatively subtle tax issues. The 1120S instructions as recently as ~2015, on the other hand, feel like vague guidance. If the phrase, "Write down your income, write down your expenses, now write down your tax. Sign that you have made no mistakes under penalty of law." makes you nervous, consider expert advice or an arrangement that avoids forming an S-corp. The state forms are generally dependent upon the federal ones, so if you make an error on the federal form, the error will flow through to the state (which may have similarly vague instructions). If I ever need to form another corporation, I will absolutely seek professional advice and hand off the filing to a trusted CPA. @Stratoscope is doing the right thing in using plenty of italics.
