Does the Valcu incorporation tool form C-corporations? S-corporations?
Delaware corporations incorporated with the Valcu incorporation tool generally default as C-corporations. C-corporations may be able to file an election with the IRS and any applicable states within certain time periods to be treated as an S-corporation. Additional information can be found here http://www.irs.gov/Businesses/Small-Businesses-&-Self-Employed/S-Corporations
and on your state's website. PLEASE CONSULT YOUR LEGAL/TAX ADVISORS FOR ADVICE.
