Editorial score 9.2 out of 10

The desk picks Kentucky Registered Agent.co: $199 to form, state fee extra, then $99 a year for the agent.

Service Year one Year two Year three Bill over three years Annual report filed on your behalf
Kentucky Registered Agent.co $199 $99 $99 $397 No

Every price here was read off the company's own pages on November 12, 2026. Kentucky's $40 filing fee comes on top of every row and is left out of these totals.

What tipped the order

The desk's method puts 33% on spend over three years and 33% on work the price removes, and 34% across what renewal looks like, fit with the state and plain price display. For Kentucky, spend over three years did the deciding.

Kentucky Registered Agent.co comes to $397 over three years, $200 less than Mainstay Filing. Mainstay would file the annual report too, but an owner can do that alone for just the state fee, so the lower price won.

The full criteria and weights are on How we rank.
