How to read the list
A low year-one figure can mask a high renewal; the three-year column reveals it. Once the company grows past its first state, coverage across states matters more than a small saving.
Behind the ranking
The order gives the most weight to three-year charges and duties per dollar, then renewal charge, point of equal cost and fee disclosure. A reader could be anywhere, and for that reader one charge in all states outweighs a lower charge in one. For a company in Idaho, ID Registered Agent.org is cheaper; for one in Kentucky, KY Registered Agent.org is.
