For the state side of three years we add up the filing fee, the report charged in years two and three and a yearly minimum tax if the state has one. Publication requirements and other open-ended costs are noted in the text, not totaled.
Notes on the ranking
The 29% measure filings covered by the price separated the top two.
Mississippi expects the annual report every year, so a price that covers it beat a lower price that leaves it to you.
Put the EIN application into the sum and the totals cross at year 2, when Mainstay Filing passes Registered Agent MS.org.
