Annual Requirements for a Delaware Limited Partnership

The centerpiece of Delaware LP compliance is the annual tax. Every domestic limited partnership formed in Delaware owes it, and understanding its shape helps you plan.

A flat tax, not a scaled report

Delaware charges LPs a flat annual tax — a fixed amount that doesn't rise or fall with the partnership's revenue or profit. This is different from corporations, which calculate franchise tax on a formula. For an LP, the number is the number, regardless of how the year went.

No financial annual report

This is worth emphasizing because people coming from corporate compliance expect a report. Delaware LPs do not file an annual report disclosing officers, activity, or finances. The obligation is a payment, not a disclosure. You're sending the state its annual tax, not filing a form describing your business.

Owed even in a dormant year

The tax is due whether or not the partnership did anything. A holding LP that sat idle all year still owes the flat tax. Budget for it as a fixed annual cost of keeping the entity alive.

Timing is the part people get wrong, so it's worth being precise.

When it's due

The annual LP tax is due by June 1 each year, covering the prior calendar year. Payment is made to the Delaware Division of Corporations, generally through its online payment system.

What happens if you miss it

Missing June 1 isn't a soft deadline. Once you're late:

• A penalty is added to the tax owed.
• Interest accrues on the unpaid balance from the due date.
• The LP falls out of good standing, which can block you from getting a Certificate of Good Standing that other states require for foreign registrations.
• Prolonged nonpayment can ultimately cause the entity to become void, at which point restoring it is considerably more expensive and involved than simply paying on time would have been.

Set a reminder well ahead

Because there's only one recurring state deadline for an LP, it's easy to forget precisely because it's rare. Put it on a calendar in early spring so you're paying before June 1, not scrambling after.

The other standing requirement runs alongside the tax: your Delaware LP must continuously maintain a registered agent with a physical Delaware address for as long as the entity exists.

Why it counts as an annual concern

Even though there's no yearly "agent filing," the agent relationship is an ongoing obligation. A commercial agent typically renews annually. An individual agent has to stay put and stay available. If the agent resigns, moves out of Delaware, or becomes unreachable, the LP is out of compliance — independent of whether the tax is paid.

Keeping it valid

• Renew your commercial agent on schedule.
• If you switch agents, file the change with the Division so there's no coverage gap.
• Make sure the agent's contact routing to you is current, so annual tax reminders and any legal process actually reach you.

An LP that's current on its tax but has an invalid agent is still out of good standing. Both requirements have to hold at once.

Delaware's annual requirements are only the state-level piece. A working LP has federal filings, and often obligations in other states.

Federal partnership return

A limited partnership files an informational federal return, Form 1065, each year and issues Schedule K-1s to the partners reporting their shares of income, deductions, and credits. The partners then report those shares on their own returns. The LP generally doesn't pay federal income tax itself, but the return still has to be filed on time. Coordinate this with your CPA — the filing deadline and any extensions are federal, separate from Delaware's June 1 tax.

Other states where the LP operates

If your Delaware LP is registered as a foreign LP in states where it does business, each of those states has its own annual or periodic requirements — reports, fees, and agent maintenance — on its own schedule. These stack on top of Delaware's; updating Delaware doesn't touch them. Keep a master list of every state where the LP is registered so nothing is missed.

Keeping the agreement current

Not a state requirement, but a practical annual habit: revisit the limited partnership agreement. As partners join or leave, contributions change, or distribution terms are renegotiated, amend the agreement so it matches reality. A stale agreement is a frequent source of disputes when money is on the line.

Because a Delaware LP has essentially one recurring state deadline, the biggest compliance risk is simply forgetting it. Mainstay Filing addresses that directly.

When we serve as your Delaware registered agent, we track the annual tax deadline and make sure reminders reach you ahead of June 1, so the payment doesn't slip past. We also maintain your Delaware registered agent coverage continuously, so that half of the compliance picture stays solid without you thinking about it.

What we don't do is file your federal partnership return or handle your other states' obligations — those belong with your CPA and the respective states. We're a filing and agent service focused on keeping your Delaware standing intact: agent in place, annual tax on your radar, formation and change filings done correctly. If you'd like, we can also help you obtain a Certificate of Good Standing when another state asks for one.
