A Missed Certificate of Continuing Use: Suspension, the March 1 Window and the Way Back

A missed certificate of continuing use can suspend an ICAP or ICIP benefit. The late window runs to March 1. MGNY files renewals. Call (212) 343-1111.
Updated September 17, 2026. The 2027/28 certificates are due January 5, 2027, and the Department of Finance accepts late renewal filings until March 1. The new season’s filings have not yet been posted.
A certificate that is not filed does not correct itself. The ICAP rule of the Department of Finance (DOF) sets out what follows, in order: benefits reduced or suspended, a notice with a short response window, and termination only after a second consecutive miss. Filing the certificate ends the suspension, so the first step after a missed January 5 is to file rather than to argue.
What does DOF do when a certificate is missing?
If an ICAP recipient misses January 5 in a required filing year, 19 RCNY section 36-13(a) allows DOF to reduce or suspend the benefits. A suspension lasts until the certificate is filed, and for that year the property is taxed as if it had no benefit. DOF’s own material says non-filing jeopardizes the benefit for the succeeding tax year. However, neither the rule nor that page says a single missed filing ends the benefit outright.
The late window runs to March 1
DOF’s ICAP and ICIP pages both state, “We are accepting late renewal filings until March 1.” An owner who discovers a missed certificate in January or February is still within that window and should file. However, a certificate filed in that window is still late, because the rule sets the taxable status date as the due date.
A second consecutive miss is a different matter
The same rule provides that recipients who fail to file for two consecutive required filing years may have their benefits terminated. On the two-year ICAP cycle, that covers roughly four years, long enough for a building to be sold and the filings forgotten.
The risk is greater for an ICIP property. The program ended in 2008 and accepts no new applicants, so an exemption that is removed cannot be replaced by a new application.
Before DOF acts, it has to give notice
DOF cannot reduce, suspend, terminate or revoke benefits automatically. Under the rule, the Commissioner must first give notice and an opportunity to be heard. The notice gives the reasons for the proposed action and the recipient’s right to present information as to why it should not be penalized.
The response is due within 10 business days of hand delivery, or 15 business days of posting by mail. These periods run from delivery or posting rather than from the day someone opens the notice.
Why is an amendment required when space changes use?
An amendment is required because the certificate records what the property is used for. Continuing eligibility for ICAP benefits is contingent on continued use of the property for the purpose specified in the application as last amended in the most recent certificate of continuing use.
The rule defines a conversion broadly, as any intentional change in the nature of the improvements for which benefits were granted, or in their use by any person, including the benefit recipient, a tenant or an occupant. A demolition, in full or in part, or any other structural change that necessarily causes a change in use, is also a conversion. Two changes do not: a change in ownership or control, provided DOF is notified, and a change in the identity of a tenant or occupant.
The amendment to the latest filed statement must be filed before a conversion of industrial use, and within 60 days of the conversion for any other kind. In addition, the rule covers an owner who has skipped the certificate: if none has been submitted, a building permit indicating a change in use is treated as a presumption of conversion.
How does MGNY handle a missed filing?
MGNY Consulting files the outstanding certificate first and then reviews the record:
- Notice and application number: Each is matched to every benefited lot.
- Record of changes: MGNY reconstructs what changed since the last accepted submission.
- Amendments: Any required amendment is prepared.
Please see the January 5, 2027 deadline post for the date and the cycle, the Exemption Renewals page for the renewal service and the ICAP page for the abatement. For a missed filing, call (212) 343-1111 with the address and the notice.
Frequently asked questions
What happens if the certificate of continuing use is not filed?
Under 19 RCNY section 36-13(a), the Department of Finance may reduce or suspend ICAP benefits when the certificate is not filed by January 5 of a required filing year. The same rule allows termination after two consecutive required filing years without a certificate.
Can a late certificate of continuing use still be filed?
A late certificate can still be filed. The Department of Finance accepts late renewal filings until March 1, but the filing is still late because it arrives after the January 5 taxable status date.
How is a suspended benefit restored?
A suspended benefit is restored by filing the outstanding certificate. Before any reduction, suspension, termination or revocation, the Commissioner must give notice and an opportunity to be heard. Responses are due within 10 business days of hand delivery, or 15 of posting by mail.
When must an amendment to the certificate be filed?
An amendment is due before a conversion of industrial use, and within 60 days of the conversion for any other kind. The rule counts any intentional change in the improvements or their use as a conversion, including one by a tenant.
