Filing Date vs Effective Date for LLC Publication (2026)
Both dates, when they differ: Section 206(a)(2) requires your publication notice to state the filing date, and the formation (effective) date too if it is different. The statute lists "the date of filing of the articles of organization with the department of state and, if the date of formation is not the date of filing of the articles of organization, the date of the formation of the limited liability company". Your Filing Receipt from the NY Department of State shows both dates, as FILE DATE and EXISTENCE DATE, and for almost every LLC they are the same day, so the publication notice states one date. The 120-day publication deadline runs from the effective (formation) date.
Filing Date vs Effective Date
Which Date Goes in Your Publication Notice
The publication notice required by Section 206 of the NY LLC Law must include the filing date, and the formation date too if it is different. Here is how the two dates on your Filing Receipt map to the notice:
| Date on Filing Receipt | What It Means | Use in Publication Notice |
|---|---|---|
| Effective date | The date NY considers your LLC legally formed | Include it too if it differs from the filing date |
| Filing date | The date DOS filed your Articles of Organization | Always include it |
For the vast majority of LLCs, the filing date and effective date are identical — the LLC becomes effective immediately upon filing. The distinction only matters when someone specifically requests a future effective date on their Articles of Organization.
Section 206(a)(2) asks for the filing date, and the formation date too when the two differ. If your Filing Receipt shows two different dates, both go in the publication notice.
When the Filing Date and Effective Date Are Different
You can request a future effective date when filing Articles of Organization with the Department of State. This is allowed up to 60 days after the filing date.
Common reasons for a future effective date:
- Starting a business on January 1 but filing paperwork in December
- Coordinating LLC formation with a business acquisition closing date
- Aligning formation with the start of a new tax year
- Waiting for a license or permit approval before the LLC officially "starts"
Example:
- You file Articles of Organization on December 15, 2025
- You request an effective date of January 1, 2026
- Filing date: December 15, 2025
- Effective date: January 1, 2026
- Dates in publication notice: filed December 15, 2025, and formed January 1, 2026
- 120-day deadline starts: January 1, 2026 (not December 15)
If your receipt's FILE DATE and EXISTENCE DATE match, the notice states one date.
The 120-Day Deadline Also Uses the Effective Date
Your 120-day publication deadline runs from the effective date, not the filing date. If you set a future effective date, your publication deadline starts later — which gives you more calendar time from when you actually filed, but the same 120 days from when your LLC officially formed.
Where to Find the Effective Date on Your Filing Receipt
When the Department of State processes your Articles of Organization, they issue a Filing Receipt. This document shows:
- Entity name — your LLC's legal name
- FILE DATE — the filing date, when DOS filed your Articles of Organization
- EXISTENCE DATE — the effective (formation) date, when the LLC legally came into existence
- DOS ID number — your entity identification number
- County — the county listed in your Articles of Organization
If you filed through an attorney, formation service, or online filing platform, they should provide this Filing Receipt. If you filed directly with DOS, you received it by mail or email.
You can also verify your LLC's effective date in the NY DOS entity database. Search by your LLC name and the record will show your formation date (which is the effective date).
What Happens If You Use the Wrong Date
Leaving the formation date out of the notice when it differs from the filing date is a common DIY mistake. The consequences depend on how different the dates are:
If the dates are the same (most common): No issue at all. This is the majority of cases.
If dates differ by a few days: Section 206(a)(2) lists both dates as items the notice includes, and §206(c) presumes the information in a published notice complies. The Department of State reviews the affidavits when you file, and each affidavit shows the notice as it ran, so if the formation date was left out, ask the Department of State or an attorney before filing (see what the statute says about newspaper errors).
If dates differ significantly (weeks apart): This could create a problem. The publication notice would omit the actual formation date, which could delay acceptance of your Certificate of Publication. You may need to correct the notice and republish, restarting the six-week clock.
How to avoid this: Before starting publication, verify both dates on your Filing Receipt. If they differ, include both dates. If you use a publication service like LLC Publishers, we check both dates against the DOS record before submitting the notice.

FAQ
How do I know if I have a future effective date?
Check your Filing Receipt from the Department of State. If the filing date and effective date are different, you have a future effective date. If they are the same (which is the most common case), your LLC was effective immediately upon filing. You can also verify in the NY DOS entity database.
I lost my Filing Receipt — how can I find the effective date?
Search the NY DOS entity database by your LLC name. The record shows your formation date, which is the effective date. You can also request a certified copy of your Articles of Organization from DOS for a fee, which shows both dates.
Does the 120-day deadline start from the filing date or effective date?
The 120-day publication deadline starts from the effective date. If you set a future effective date, the clock starts on that future date — not when you submitted the paperwork. This means you have more calendar time from your actual filing, but the statutory 120-day window remains the same.
My attorney filed my LLC — how do I get the Filing Receipt?
Ask your attorney or formation service for a copy of the Filing Receipt. They should have received it from DOS when the filing was processed. If they cannot provide it, search the NY DOS entity database to verify your LLC's effective date directly.
Can I change the effective date after filing?
No. Once the Articles of Organization are filed and approved by DOS, the effective date cannot be changed. If you need a different formation date, you would need to dissolve the LLC and form a new one — which is impractical. For publication, the notice states the filing date and, if it differs, that effective (formation) date.
What if my formation service used the wrong date in my publication notice?
Section 206 does not say that a wrong date voids the publication, and §206(c) presumes the information in a published notice complies, although the date is one of the items Section 206(a)(2) lists. The Department of State reviews the affidavits when you file, and a significant difference may mean republishing. Contact the formation service to discuss correction options, or reach out to us for guidance.
Key Takeaways
- Include the filing date in your publication notice, plus the effective (formation) date if it differs: Section 206(a)(2) requires both
- In most cases, the filing date and effective date are the same day — no confusion needed
- If you requested a future effective date (up to 60 days out), that date goes in the notice alongside the filing date
- The 120-day publication deadline also starts from the effective date, not the filing date
- You can verify your LLC's effective date in the NY DOS entity database
- Using the wrong date could require republication — verify before starting
- If your attorney or service filed for you, ask them for the Filing Receipt before beginning publication
- Future effective dates are uncommon: for most LLCs the two dates match, so the notice states one date
