Which service fits which owner

Side hustle

The worry is what the LLC costs you every year while the income is small. Here that is $199 with Mainstay Filing plus $400 to Delaware Secretary of State when the report is due. Bizee is lower in year 1 ($110 against $309), but check its year-2 cell before you take the saving.

First-time owner

Most of the work comes after the filing: the EIN, an operating agreement, an agent address and the Annual LLC Tax, due Annual alternative-entity tax due on or before June 1. Mainstay Filing prepares and files the formation and the report, applies for the EIN, and has no operating-agreement upcharge.

Online business

You will probably be asked for a business address by a bank or a payment processor. The registered agent address is on the public record and is not a business mailing address; Mainstay Filing says its address can’t stand in for one, so plan a separate mailing address. Required registered agent in Delaware: The LLC itself, a Delaware resident, or a business entity formed in Delaware or authorized to do business there.

Startup with co-founders

Two things to settle before filing: who owns what, in an operating agreement, and who is responsible for the yearly paperwork. With Mainstay Filing the agreement is not an extra charge and the report is filed for you, so the $1,507 three-year figure above is the whole budget apart from legal advice you choose to buy.

Non-US owner

Mainstay Filing applies for the EIN as part of formation. It charges a one-time $99 for founders with no SSN or ITIN (a faxed Form SS-4), on top of the $199 and the $110 Delaware filing fee.

Questions

Do I need an operating agreement in Delaware?

Whether Delaware requires one is a legal point we have not checked state by state; with more than one owner, a written agreement settles who decides what. Mainstay Filing does not charge extra for one.

Can I be my own registered agent in Delaware?

The LLC itself, a Delaware resident, or a business entity formed in Delaware or authorized to do business there. If you meet that rule you can, and the cost is $0 plus the address on the public record.

Mainstay Filing: $199 plus the $400 state report fee in year 2. The others vary: Northwest Registered Agent $525, ZenBusiness $599, Bizee $549, LegalZoom $649.
