Delaware LLC New York: 120-Day Deadline and Cure Guide
The Short Answer
The 120-day clock isn't about when you start publishing — it's the deadline to FILE proof that you finished. Under §802(b)(i) of the NY LLC Law, a foreign LLC has 120 days from the date its Application for Authority was filed to complete six consecutive weekly publications in two county-designated newspapers and file the Certificate of Publication — with both newspapers' affidavits annexed — with the NY Department of State. Both steps have to land inside that single window. Finishing your sixth week of ads on day 119 and filing the certificate on day 121 still results in suspension: "start publishing within 120 days" is wrong, and so is "complete publication within 120 days" if that's read as covering only the ads and not the filing.
Every foreign LLC — Delaware-formed or not — follows this same §802 mechanic: two newspapers designated by your New York county's clerk, once a week for six consecutive weeks, then a Certificate of Publication filed within 120 days of the Application for Authority. For the full statute and the seven-step process, see our foreign LLC publication guide; for how Delaware fits into all of this, see the Delaware LLC publication hub. This page covers what happens at the deadline itself: how to compute it, what a suspension does (and doesn't) mean, how to cure one, and how the separate NY LLC Transparency Act does — or doesn't — apply.

What the 120-Day Deadline Actually Requires
§802(b)(i) sets a single 120-day window, running from the date your Application for Authority was filed with the NY Department of State, that has to contain two separate things:
- Publication — a copy of your Application for Authority, or a notice containing its substance, published once a week for six successive weeks in two newspapers of your New York county — one weekly, one daily — designated by the county clerk.
- Filing — proof of that publication, consisting of the Certificate of Publication with both newspapers' affidavits of publication annexed, filed with the NY Department of State.
The statute's own language is explicit that both have to be done inside the window. If, "within one hundred twenty days after the filing of its application for authority... proof of such publication... has not been filed with the department of state, the authority of such foreign limited liability company to carry on, conduct or transact any business in this state shall be suspended, effective as of the expiration of such one hundred twenty day period." The measuring event is the filing of proof — not the date the last ad ran, and not the date publication began.
What actually has to happen by day 120
Not "start publishing." Not "finish publishing." The Certificate of Publication, with both newspapers' affidavits annexed, has to be filed with the NY Department of State before the 120th day after your Application for Authority was filed. Publication itself typically takes 8-10 weeks once you account for six weekly runs plus the time each newspaper needs to prepare and mail its affidavit afterward — which is why starting late leaves very little room for the filing step.
Your 120-Day Deadline Calculator
Your clock starts on the date your Application for Authority was filed with the NY Department of State — not your Delaware formation date, not the date you began operating in New York, and not the date you first learned about the publication requirement. That filing date is what the entire 120-day calculation runs from, and it's printed on one document you already have: your DOS filing receipt.
That same receipt also prints your New York county on a COUNTY: line near the top — the two facts you need most, your deadline and your county, sit on the same one-page document. If you don't have it handy, see the county and exact price guide in this series for the other place the county appears, or use the lookup tool to confirm both.
The formula: Application for Authority filing date + 120 calendar days = the deadline to have your Certificate of Publication, with both affidavits annexed, filed with the NY Department of State. Calendar days, not business days — weekends and holidays count toward the 120.
| If your Application for Authority was filed on... | Your deadline to file proof of publication is... |
|---|---|
| January 15 | May 15 |
| March 15 | July 13 |
| May 15 | September 12 |
| July 15 | November 12 |
| September 2 | December 31 |
| November 15 | March 15 (following year) |
Illustrative — count 120 calendar days forward from your own filing date rather than rounding to the nearest row above. The table shows how the math shifts across months of different lengths; it isn't a lookup of your specific deadline.
Publication itself needs six consecutive weekly runs — 8-10 weeks in practice once each newspaper's own production schedule and the affidavit mail time are factored in — which means most of the 120-day window is consumed by the newspaper schedule, not the filing step. That's the arithmetic behind why the deadline is tighter than "120 days" sounds.

Get StartedWhat Happens If You Miss the Deadline: Suspension and Its Carve-Outs
If proof of publication isn't filed within 120 days, §802(b)(i) suspends "the authority of such foreign limited liability company to carry on, conduct or transact any business in this state," effective as of the day the 120-day period expires. That's a suspension of the authority to operate — not a dissolution, and not, by itself, a bar on everything else about the LLC's existence.
The very next sentence of that same paragraph narrows what the suspension actually touches. Neither the failure to publish nor the suspension itself shall:
- limit or impair the validity of any contract or act of the foreign LLC;
- limit or impair any right or remedy of any other party under or by virtue of any such contract, act, or omission;
- limit or impair the right of any other party to maintain any action or special proceeding on any such contract, act, or omission;
- limit or impair the right of the foreign LLC to defend any action or special proceeding in this state; or
- result in any member, manager, or agent of the LLC becoming personally liable for its contractual obligations or other liabilities.
What §802 does not say
§802 preserves the other party's right to sue the suspended LLC, and it preserves the suspended LLC's right to defend itself. It does not say anything, one way or the other, about the suspended LLC bringing a lawsuit of its own — the statute is silent on that specific question. Because the statute doesn't address it directly, the accurate description is that a suspended LLC's authority to maintain an action — that is, to bring or pursue a lawsuit — can be challenged. That's a description of legal risk, not a quote from the statute, and it is not the same as saying the LLC categorically cannot sue. If litigation capacity matters to your situation, a business attorney familiar with New York law can advise on the specific facts.
§802 Suspension vs. §808: Two Different Situations
It's easy to reach for §808 of the NY LLC Law when researching what a publication suspension means for a foreign LLC's ability to sue — the two sections sit in the same article and both touch on litigation rights. They govern two different situations, and treating them as interchangeable is the most common error in this area.
§808 applies to a foreign LLC that never registered in New York at all. Its trigger is doing business in New York "without having received a certificate of authority to do business in this state." For that LLC, §808(a) is explicit: it "may not maintain any action, suit or special proceeding in any court of this state unless and until such limited liability company shall have received a certificate of authority in this state." That's a direct statutory bar, stated in the law itself.
§802 applies to a different LLC — one that already has a certificate of authority. It filed its Application for Authority, New York accepted it, and it simply missed the 120-day window to file proof of publication. As covered above, §802 doesn't contain that same bar — it's silent on the suspended LLC's own right to sue, which is exactly why "can be challenged" is the accurate description, not a flat "cannot sue."
| §802 suspension (this page) | §808 (never registered) | |
|---|---|---|
| Trigger | Certificate of authority was obtained; proof of publication not filed within 120 days | Doing business in NY without ever obtaining a certificate of authority |
| Statute's own words on suing | Silent — doesn't address the LLC's own right to sue | Explicit bar: "may not maintain any action, suit or special proceeding" |
| Right to defend a lawsuit | Explicitly preserved | Explicitly preserved |
| Validity of existing contracts | Explicitly preserved | Explicitly preserved |
| Personal liability for members/managers | Explicitly not created | Explicitly not created |
| How it resolves | File proof in substantial compliance — suspension "shall be annulled" | Obtain a certificate of authority |
A Delaware LLC that already holds a New York certificate of authority and simply missed its 120-day publication deadline is a §802 situation — never a §808 one. §808 describes a foreign LLC that hasn't registered with New York at all, which is a different fact pattern from a lapsed publication deadline.
How to Cure a Suspension
A §802 suspension isn't permanent, and there's no separate penalty or late fee stacked on top of the standard publication and filing costs. The same paragraph of the statute states that "at any time following" a suspension, if the LLC causes proof of publication "in substantial compliance" with the publication requirements — everything except the 120-day window itself — to be filed with the Department of State, "such suspension... shall be annulled."
In practical terms, curing a suspension means completing the six consecutive weekly publications in the correct county-designated newspapers, collecting both affidavits, and filing the Certificate of Publication with the $50 filing fee. There's no separate cure form and no additional fee beyond that standard $50 — whenever the filing happens, even long after the original 120-day window closed, the suspension lifts.
Cure has no deadline of its own
Unlike the original 120-day window, "substantial compliance" filed after a suspension has no second countdown attached to it. The statute says the suspension is annulled once proof is filed — it doesn't set a further deadline for filing it.
Does the NY LLC Transparency Act Apply to a Delaware LLC?
No. After Governor Hochul's December 19, 2025 veto of an earlier, broader version of the bill, the New York LLC Transparency Act (LLCTA) reaches only LLCs formed under the law of a foreign country — not LLCs formed in another U.S. state. Delaware is a U.S. state, so a Delaware-formed LLC registering in New York is exempt from the LLCTA's beneficial-ownership disclosure filing, regardless of when it registered here.
Delaware is a U.S. state, so a Delaware-formed LLC registering in New York is exempt from the LLCTA's beneficial-ownership disclosure filing.
The narrowed law took effect January 1, 2026. For the non-U.S. LLCs it does reach: one authorized to do business in New York before that date must file its disclosure by December 31, 2026; one authorized on or after that date must file within 30 days of authorization. The filing fee is $25.
A separate law from §802 publication
The LLCTA and §802 publication are unrelated requirements administered under different parts of the law. A Delaware LLC has zero LLCTA filings to make — but it still has to complete §802 publication and file proof within 120 days like every other foreign LLC, regardless of the LLCTA.
What Counts as Doing Business in New York
None of the deadline mechanics above matter unless your Delaware LLC actually crosses the threshold into "doing business" in New York in the first place — the trigger for having to file an Application for Authority, and therefore publish, at all. That threshold is fact-specific and shaped largely by case law, not a fixed checklist.
§803 of the NY LLC Law supplies a non-exclusive list of activities that, by themselves, do not constitute doing business — among them, maintaining or defending a lawsuit, holding member or manager meetings, and maintaining bank accounts in New York. The statute's own language — "without excluding other activities that may not constitute doing business in this state" — confirms the list only rules a few things out; it doesn't establish a complete standard, and it doesn't produce a yes-or-no verdict for any specific LLC's own mix of activities.
"Doing business" is a fact-specific question, not a checklist — §803 supplies only a non-exclusive list of activities that don't count on their own.
The line can be blurry. If you're unsure whether your activities constitute "doing business" in New York, consult with a business attorney familiar with New York law. Our foreign LLC publication guide walks through examples of activities that typically do and don't cross that line.

Get StartedFAQ: Delaware LLC 120-Day Deadline and Cure
Is the 120-day deadline for starting publication or finishing it?
Neither, exactly. The 120 days run from your Application for Authority's filing date to the date the Certificate of Publication — with both newspapers' affidavits annexed — is filed with the NY Department of State. Under §802, both have to land inside that same window: the six weeks of publication and the Certificate of Publication filing. Finishing the ads without filing the certificate by day 120 still results in suspension.
How do I calculate my own 120-day deadline?
Add 120 calendar days to the date your Application for Authority was filed with the NY Department of State — that filing date is printed on your DOS filing receipt. See the calculator table above for how the math works across different months.
What happens if my Delaware LLC's authority gets suspended?
Your LLC's authority to carry on, conduct, or transact business in New York is suspended, effective as of the 120-day deadline. Existing contracts stay valid, the other party can still sue you, you can still defend yourself in court, and no member or manager becomes personally liable. Your own authority to maintain an action — that is, to bring or pursue a lawsuit — can be challenged until you cure the suspension.
Is a §802 suspension the same as §808?
No. §808 applies to a foreign LLC that never obtained a certificate of authority at all, and it explicitly bars that LLC from suing until it does. §802 applies to an LLC that already has a certificate of authority and simply missed the 120-day publication deadline — a different situation, and the statute doesn't contain that same explicit bar. See the comparison table above.
How do I cure a §802 suspension?
File proof of publication — the Certificate of Publication with both affidavits annexed — in substantial compliance with the publication requirements (other than the 120-day window) at any time after the suspension. The statute states the suspension "shall be annulled" once that's filed. There's no separate cure fee beyond the standard $50 filing fee.
Does the NY LLC Transparency Act apply to my Delaware LLC?
No. After the December 19, 2025 veto, the LLCTA reaches only LLCs formed under the law of a foreign country. A Delaware LLC is a U.S.-state entity, so it has no LLCTA filing to make — but it still has to complete §802 publication separately.
Does missing the deadline mean my Delaware LLC has to dissolve or reform?
No. Suspension is an administrative status, not a dissolution. Your LLC continues to exist; its authority to do business in New York is what's suspended, and that authority is restored once you file proof of publication in substantial compliance.
What if I'm not sure my Delaware LLC's activities require registering in New York at all?
That's a fact-specific "doing business" question under §803 of the NY LLC Law, which lists only a non-exclusive set of activities that don't count — it isn't a yes/no checklist. If you're unsure, consult with a business attorney familiar with New York law.
Key Takeaways
- The 120-day deadline is to FILE proof of publication, not just to start or finish the ads. Both the six weeks of publication and the Certificate of Publication filing have to land inside the same 120-day window from your Application for Authority's filing date.
- Calculate your own deadline from your DOS filing receipt — Application for Authority filing date plus 120 calendar days equals the deadline to file proof. The same receipt prints your county too.
- Suspension is administrative, not fatal. §802's own carve-outs preserve contract validity, the other party's right to sue, your LLC's right to defend itself, and shield members and managers from personal liability.
- §802 is silent on the suspended LLC's own right to sue — it never says "cannot sue." The accurate description is that authority to maintain an action can be challenged, which is different from §808's explicit statutory bar for LLCs that never registered at all.
- Cure has no deadline of its own. File proof of publication in substantial compliance at any time after a suspension, and it's annulled — no extra fee beyond the standard $50.
- Delaware LLCs are exempt from the NY LLC Transparency Act. After the December 19, 2025 veto, it reaches only LLCs formed under a foreign country's law.
- "Doing business" is a fact-specific question, not a checklist — §803 supplies only a non-exclusive list of activities that don't count on their own.
- LLC Publishers handles the entire process for a flat $395–$1,795 by county, plus the $500 foreign-LLC add-on — including hitting the deadline in the first place. View pricing →
