Kentucky registered agent cost in 2026: first year, renewal and the three-year tally

Service First year Second year Third year Three-year tally Holds its price at renewal
KY Registered Agent.org $99 $99 $99 $297 Yes
Mainstay Filing $149 $149 $149 $447 Yes
Kentucky Registered Agent.co $99 $99 $99 $297 Yes

Each price comes from the company's own site, read on November 12, 2026. Kentucky charges its own fees the same way whichever agent you name.

Why the order falls this way

Points here: 25% for cost across three years, 25% for coverage of the price and 50% across renewal terms, state-by-state fit and pricing clarity. Kentucky came down to cost across three years.

KY Registered Agent.org tallies $297 across three years, $150 below Mainstay Filing. If Kentucky is the only state, fifty-state coverage adds little, and the lower yearly price takes the points.

Every criterion and weight appears on How we rank.
