The Real Cost of Forming and Running a Delaware Limited Partnership

Getting the limited partnership into existence involves a handful of upfront costs. Only some are mandatory.

The state filing fee (required)

To create the LP, you file the Certificate of Limited Partnership with the Delaware Division of Corporations, and the state charges a filing fee for it. This is unavoidable — it's the price of the legal act that brings the entity into being. The exact amount is set by the Division and shown on your receipt.

Expedited processing (optional)

Standard processing runs in business days. If you're racing a closing or a deadline, Delaware sells expedited tiers — including same-day and faster handling — for additional fees. Most formations don't need it, but the option exists when timing is tight.

Name reservation (optional)

If you want to lock your chosen name before you're ready to file, Delaware lets you reserve an available name for a set period for a fee. It's genuinely optional — most people simply file when they're ready rather than reserving first.

Certified copies (optional)

Banks, lenders, or foreign-registration filings sometimes want a certified copy of the certificate. Delaware charges for certification. You can order it at formation or later, only if and when you actually need it.

A Delaware LP isn't a one-and-done expense. Keeping it alive and in good standing means a predictable annual outlay to the state.

The annual Delaware LP tax (required)

This is the big recurring item. Every domestic Delaware limited partnership owes a flat annual tax to the state, due by June 1 each year. Two things to understand:

• It's a flat tax, not a scaled report — the amount doesn't depend on your revenue or profit.
• There's no financial annual report for LPs. Unlike corporations, you're paying, not disclosing.

The tax is owed even if the partnership was dormant all year. Miss the June 1 deadline and penalties plus interest accrue, and prolonged nonpayment can render the entity void — so this is not a bill to let slide.

Loss of good standing has its own price

If you fall behind, restoring good standing costs the back taxes plus penalties and interest — always more than staying current would have. And because other states require a Delaware Certificate of Good Standing to keep foreign registrations valid, a lapse in Delaware can trigger costs and problems in every state where the LP is registered.

Delaware requires every LP to maintain a registered agent with a physical Delaware address for the life of the entity. There are two ways to bear this cost.

A commercial registered agent (recurring fee)

Most out-of-state owners pay a commercial service an annual fee to serve as their Delaware agent. In exchange, the service's professional address sits on the public record instead of yours, and someone is always available to receive service of process and forward state mail. For a fund or holding LP whose partners are spread across states, this is the standard, sensible cost.

Serving as your own agent ("free," with strings)

If a partner has a physical Delaware address and is reliably available during business hours, they can serve as agent at no service fee. The hidden costs: that person's address becomes public, and any lapse in availability — a move, a vacation, a missed delivery — can put the LP out of compliance and risk a missed lawsuit. For most people forming a Delaware LP from out of state, this isn't a realistic option anyway.

Delaware LPs are frequently used as vehicles that hold or operate assets in other states. Each state you touch can add cost.

Foreign qualification fees

If your LP does business in another state, you'll likely have to register there as a foreign LP, which means that state's filing fee, its registered agent fee, and often the cost of obtaining a Delaware Certificate of Good Standing to attach to the application.

Ongoing compliance in each state

Every state where the LP is qualified may impose its own annual or periodic fees and requirements. These stack on top of Delaware's annual tax — they don't replace it. A Delaware LP operating in three states effectively carries four compliance calendars and four sets of fees.

A single agent across states can trim the overhead

Using one commercial provider as your agent across every state where the LP is registered won't eliminate the state fees, but it consolidates the agent cost and the renewal dates, which reduces the administrative burden of tracking many providers.

Some of the most valuable spending on an LP is optional and goes to professionals rather than the state.

Legal drafting of the limited partnership agreement

This is the document that actually governs the deal — capital contributions, profit and loss allocation, the general-versus-limited-partner split, and dissolution terms. For anything beyond the simplest arrangement, having an attorney draft or review it is money well spent. This is precisely the work we, as a filing service, don't do.

Tax and accounting

A partnership files Form 1065 and issues K-1s, and the allocation rules can get intricate. A CPA who understands partnership taxation is a recurring cost most serious LPs choose to bear.

What Mainstay Filing covers

Our coverage runs as one flat yearly price: the Delaware filing work, the registered agent for as long as we serve, and handling the June tax obligation all live under that single figure, so none of them shows up as its own charge. The state fees themselves pass through — what you're displayed on the receipt is what's charged, with no markup buried in the text. We keep the state-facing costs transparent; the legal and tax spending is yours to arrange with your own advisors.
