No.1
Our top pick
1. DE Registered Agent.org: best for a Delaware LLC that intends to stay put
$199 to form, then $99 a year for the agent, with the state fee extra
Score9.4out of 10
First place: DE Registered Agent.org. The formation charge is $199 over the state fee, then $99 annually for the agent.
An in-state street address serves as the registered office, and papers served on the company are scanned into your online account.
The Annual LLC Tax lies outside its published prices, so you file it with Delaware every year.
Over three years it costs less than Mainstay Filing, and cost is one of our two most heavily weighted criteria.
In the price
- Articles prepared and filed
- A first year as your registered agent
Why pick it
- Includes your registered agent for the first year
- A $199 service charge plus the state filing fee
- Year-two agent charge: $99
Weak spots

Second place: Delaware Registered Agent.ai. The formation charge is $199 over the state fee, then $99 annually for the agent.
An in-state street address serves as the registered office, and papers served on the company are scanned into your online account.

3. Mainstay Filing: best for the formation, the agent and the annual tax under one charge
$199 a year plus the state fee ($309 due at checkout)
Score8.7out of 10
Third place: Mainstay Filing. $199 a year buys the Delaware filing, registered agent service and the annual tax, and renewal is $199.
At renewal Mainstay prepares and files the Annual LLC Tax for you. Delaware charges $400 every year for it, due annual alternative-entity tax due on or before June 1, and lateness adds $200; Mainstay passes the state fee along at cost.
DE Registered Agent.org costs $200 less over three years, and Mainstay Filing trails it on that criterion.
In the price
- Preparation and filing of the formation document
- Your registered agent all year long
- Annual tax prepared and filed on your behalf
- EIN application prepared
Why pick it
- Delaware's fee is passed along at cost
- One yearly charge of $199 that covers the annual tax
- Renews at $199 with nothing added
- Covers the EIN application
Weak spots
- Its agent charge after year one is $100 a year above DE Registered Agent.org's

The reasoning for the order
Two criteria carry 31% each in this ranking, charge over three years and work taken off the founder. Renewal conduct, fit with local rules and pricing in plain sight share 38%, and in Delaware the decisive one was charge over three years.
Over three years DE Registered Agent.org totals $397, $200 less than Mainstay Filing. Mainstay would file the Annual LLC Tax as well, yet an owner can do it alone for the state fee, so the lower charge carried the ruling.
Each criterion and its weight appear on How we rank.
