Delaware: the ranked services

Three-year cost and paperwork completed carry the most weight; how we grade lists all five.

1. Mainstay Filing: best for no annual tax to prepare

Read this one first
$199 a year plus the state fee ($309 due at checkout)

This chapter recommends Mainstay Filing above the others, because a yearly fee of $199 pays for the formation, the registered agent and the annual tax, and the second year is $199 again.

DE Registered Agent.org costs $200 less over three years; this service still ranks higher because it does more of the work.

The Annual LLC Tax is part of the service, and Delaware's $400 fee is billed at cost.

The sections

  1. Section 1

    Search the register for the name

    Start in the business name records of the Delaware Secretary of State. A name already registered in Delaware may cause the filing to be rejected.

    Consider whether a matching web address is available too.

  2. Section 2

    Designate the registered agent

    Every LLC must name a registered agent with an in-state street address. The LLC itself, a Delaware resident, or a business entity formed in Delaware or authorized to do business there.

    The address has to be a registered office in Delaware. An entity agent keeps a business office there that is generally open; an individual agent has to be generally present there. A virtual office or mail-forwarding service alone does not qualify.

    Each recommended service can act as your registered agent.

  3. Section 3

    File alone or pay for assistance

    An owner who files alone pays only the $110 state fee. A service adds $199 and prepares the forms; the recommended list ranks them.

  4. Section 4

    Section four is the Certificate of Formation of a Limited Liability Company

    Required: the Certificate of Formation of a Limited Liability Company, the $110 fee, and delivery to the Delaware Secretary of State. Authority: 6 Del. C. § 18-201.

    Reference: delcode.delaware.gov, as published October 2026

  5. Section 5

    Secure the LLC's EIN

    After formation, an EIN identifies the LLC to the IRS and lets it open accounts in its own name. The Mainstay Filing annual price already includes this section.

  6. Section 6

    Record how the company will be run

    A one-member Delaware LLC should still have a written operating agreement in its records.

  7. Section 7

    Handle the recurring Delaware filing

    Good standing depends on the Annual LLC Tax, which is filed every year and costs $400, with a deadline of annual alternative-entity tax due on or before June 1. The late charge is $200.

    Reference: legis.delaware.gov, as published October 2026

What each section costs in Delaware

SectionPaid toAmount
Creating the LLC Paid to the state$110
Annual LLC Tax Paid to the state$400 every year
Late charge Paid to the state$200
Service, if hired The service$199 in year one
State fees across years one to three Paid to the state$910

Rows for the state rely on Delaware's published fee schedules (listed in the bibliography below), and each service row uses that company's own price. For three years the state row adds the filing, the report in year two, the report in year three and any minimum tax.

The reasoning behind the ranking

On chapters the price completes (30% of the ranking) came first, with next.

Handling the Annual LLC Tax outweighed the lower price once the weights were applied.
