Forming a US LLC takes about a week. Keeping it in good standing takes a calendar. This LLC annual compliance checklist walks through everything a US LLC owner needs to file, renew, and pay in 2026: state annual reports, federal tax returns, franchise taxes, registered agent renewal, and the current status of BOI reporting.
The stakes are wildly uneven, which is exactly why a checklist helps. Miss a state annual report and you will usually pay a small late fee. Miss Form 5472 as the foreign owner of a single-member LLC and the starting penalty is $25,000. Half the job is knowing which items are routine and which are radioactive.
Work through each section below, note the items that apply to your LLC, and put the deadlines somewhere you will actually look. Most owners end up with five or six recurring dates. That is the whole system.
Start with your state: the annual report
Almost every state requires a periodic report to keep your LLC active. Most are annual, a handful are biennial, and a few states skip them entirely. The report itself is usually simple: confirm your address and your registered agent, then pay the fee.
Deadlines follow two patterns. Some states set one fixed date for everyone. Others tie the deadline to your formation anniversary, so two LLCs in the same state can owe reports in different months. Wyoming, for example, charges $60 and up for its annual report, due on the first day of your anniversary month.
Fees and dates vary widely, so check your specific state in our state guides rather than assuming your neighbor’s deadline is yours.
Franchise taxes are a separate bill
Some states also charge a franchise tax: a flat fee for the privilege of existing there, unrelated to income. Delaware is the classic case. Every Delaware LLC owes a $400 franchise tax by June 1, even with zero revenue. California is known for a hefty annual LLC fee as well. If these recurring costs matter to you, read up on a state before you form there.
Confirm your registered agent through 2026
Every state requires a registered agent: a person or company with a physical street address in the state, available during business hours to receive legal notices. The service is billed annually, and it is easy to let a renewal lapse when the card on file expires.
A lapsed agent is worse than it sounds. If someone sues your LLC and the papers cannot be delivered, you can lose by default without ever knowing there was a case. States also treat a missing agent as grounds to revoke good standing. A reliable registered agent service keeps this box quietly checked every year.
Federal filings depend on how your LLC is taxed
The IRS has no single filing called “LLC”. Your federal obligations depend on who owns the company and how it is classified. Here are the three common situations; if yours is unusual, US tax filing help exists for exactly this reason.
Single-member LLC with a foreign owner
You file Form 5472 attached to a pro forma Form 1120, due April 15 for a calendar-year LLC. It is an informational return, not a tax bill, and in most cases it is required even if the LLC earned nothing: transactions between you and the LLC, including simply funding its bank account, are typically reportable.
The penalty for skipping it is $25,000, which makes it the most dangerous item on this checklist. Separately, if the LLC earned US-source income effectively connected to a US trade or business, you may also need to file Form 1040-NR personally, which requires an ITIN.
Multi-member LLC
A multi-member LLC files Form 1065, a partnership return, and issues a Schedule K-1 to each member. In 2026 the deadline is March 16, since the usual March 15 falls on a Sunday. If any member is a foreign person, the LLC generally must also withhold tax on that member’s share of effectively connected income and report it on Forms 8804 and 8805.
Single-member LLC with a US owner
The simplest case: the LLC is disregarded and its income lands on Schedule C of your personal Form 1040, due April 15. An S-Corp election can trim self-employment tax in some cases, but it is only open to US citizens and residents.
Check your BOI reporting status
Beneficial ownership reporting has changed more than once, so here is where it stands under FinCEN’s 2025 interim final rule: companies formed in the United States are exempt from BOI reporting. Foreign companies that registered to do business in a US state must still file.
In practice, a Wyoming or Delaware LLC formed by a non-resident currently has no BOI report to make, while a foreign entity qualified into a US state does. These rules can change again, so verify before you rely on the exemption. We track changes like this one; our compliance reminder page stays current so you do not have to.
Sales tax: the quiet obligation
Sales tax lives at the state level and does not care where your LLC was formed. You owe it where your customers are, once you cross a state’s nexus threshold: either a physical presence like inventory in a warehouse, or economic nexus, commonly around $100,000 in annual sales into that state.
Two practical notes. If you sell through Amazon or another marketplace, marketplace facilitator laws mean the platform collects and remits sales tax on those orders in essentially every state that has one. But direct sales through your own store are your responsibility, and FBA inventory can create physical nexus in states you have never visited. Track where your stock sits and where your revenue concentrates.
Build one compliance calendar
Compliance failures are rarely about difficulty; each filing above is manageable. Owners get burned by dates, because deadlines are scattered across state and federal systems that never remind you in one place. Consolidate them yourself. For 2026, the big fixed dates are:
- March 16: Form 1065 and K-1s for multi-member LLCs
- April 15: Form 5472 with pro forma 1120 for foreign-owned single-member LLCs, and Form 1040 for US owners
- June 1: Delaware LLC franchise tax
- June 15: Form 1040-NR for most non-resident individuals with no US wage withholding
- Your state’s date: annual report and registered agent renewal, often tied to your formation anniversary
Extensions exist for the tax returns, Form 7004 for the 1065 and the pro forma 1120, but an extension moves the paperwork, not any tax owed. Plug your dates into our US tax deadline calendar and export them straight to the calendar you actually check.
What missed filings actually cost
Penalties are why this checklist deserves an hour of your year. Here is what skipping each item typically costs:
| Missed filing | Who it hits | Typical consequence |
|---|---|---|
| Form 5472 + pro forma 1120 | Foreign-owned single-member LLCs | $25,000 penalty per form, per year |
| Form 1065 | Multi-member LLCs | Per-partner, per-month penalty that stacks for up to 12 months |
| State annual report | LLCs in most states | Late fees, loss of good standing, eventual administrative dissolution |
| Franchise tax | LLCs in states that charge one | Fixed penalty plus interest, and loss of good standing |
| Registered agent lapse | All LLCs | Missed lawsuits and state notices, possible dissolution |
| Sales tax registration | Sellers past a nexus threshold | Back taxes paid from your own pocket, plus penalties and interest |
A dissolved LLC can usually be reinstated, but reinstatement costs more than compliance ever would, and some states make you back-pay every missed year. If you are not sure which rows apply to you, a free tax consultation is the fastest way to get a straight answer for your setup.
Frequently asked questions
Does my LLC need to file anything if it made no money?
Usually yes. Form 5472 reports transactions with the foreign owner, not profits, and simply moving money into the LLC’s bank account typically counts as reportable. Your state annual report and registered agent renewal are also due regardless of revenue.
What happens if I miss my state annual report?
In most states you pay a late fee first and lose good standing if the report stays unfiled. Leave it long enough and the state administratively dissolves the LLC, which can unsettle your bank and your contracts. Reinstatement is usually possible, just slower and more expensive than filing on time.
Do US-formed LLCs still file a BOI report in 2026?
Under FinCEN’s 2025 interim final rule, no: companies formed in the US are exempt. Foreign companies registered to do business in a US state must still file. The rule has shifted before and could shift again, so confirm the current status before relying on it.
Which compliance deadline matters most for non-resident owners?
April 15. That is the due date for Form 5472 with the pro forma 1120, the one filing on this LLC annual compliance checklist that carries a $25,000 penalty. If you set a single reminder all year, make it this one, and file Form 7004 for an extension if you will not be ready in time.
