Everything You Need to Know About E-Rate Deadlines

E-Rate is a deadline-driven program. A district, library, consortium, or service provider can do almost everything right and still lose funding if a deadline is missed.

The challenge is that E-Rate does not have one deadline. It has a chain of deadlines: Form 470, the 28-day waiting period, the Form 471 filing window, Form 486, SPAC, service delivery, invoice filing, invoice extensions, service delivery extensions, appeals, SPIN changes, service substitutions, and post-commitment corrections.

This guide explains the E-Rate deadlines applicants and service providers need to track, with special attention to the last day to invoice, the FY2027 filing window, SPAC, and Form 486.

Quick E-Rate Deadline Table

Why E-Rate Deadlines Are So Easy to Miss

E-Rate deadlines overlap across funding years.

In the same month, an applicant might be:

• Invoicing last year's services.
• Receiving and reviewing funding commitments for the current year.
• Filing Form 486 for newly started services.
• Preparing next year's Form 470.
• Updating EPC entity data for the upcoming filing window.
• Coordinating with service providers on SPAC or SPI invoicing.

That is why E-Rate deadline management should not be a once-a-year activity. The program runs year-round, and many deadlines are specific to each Funding Request Number, or FRN.

The FY2027 E-Rate Filing Window

As of June 14, 2026, USAC has not announced the FY2027 FCC Form 471 filing window dates.

That matters because the Form 471 filing window is not a fixed statutory date that applicants should guess. USAC announces the exact opening and closing dates each year.

What we know:

• FY2027 is the funding year that runs from July 1, 2027 through June 30, 2028.
• The FY2027 Form 471 filing window will be announced by USAC before it opens.
• Applicants must certify Form 471 by 11:59 p.m. ET on the closing date of the filing window.
• A Form 471 filed after the window closes is considered out-of-window unless relief applies.

For context, the FY2026 filing window was January 21, 2026 through April 1, 2026. That is an example of the recent timing pattern, not an official FY2027 date.

Applicants should use USAC's Upcoming Dates page, E-Rate News Brief, EPC notices, and the annual filing window page as the source of truth.

FCC Form 470 Deadline

The FCC Form 470 starts the competitive bidding process.

USAC states that Form 470 can be filed for a funding year once USAC posts notice that the Form 470 for that funding year is available. USAC says this notice is generally posted about 12 months before the start of a funding year.

The Form 470 deadline is tied to the Form 471 filing window. The Form 470 must be certified in EPC at least 28 days before the close of the Form 471 filing window for the funding year in which the products or services are requested.

That is the minimum deadline. It is not the best practice deadline.

Applicants should file Form 470 early enough to allow time for:

• Vendor questions.
• RFP addenda.
• Site walks, if needed.
• Bid evaluation.
• Board approval.
• Contract review and signature.
• Correction of Form 470 or RFP issues.
• Form 471 preparation.

For FY2026, the last date to certify Form 470 and still complete the minimum 28-day waiting period before the April 1, 2026 Form 471 deadline was March 4, 2026. FY2027 will have its own date once USAC announces the FY2027 Form 471 closing date.

FCC Form 471 Deadline

The FCC Form 471 is the funding request.

Applicants must file and certify Form 471 in EPC during the annual filing window. USAC announces the exact dates and times each year. The closing date matters because late applications are out-of-window.

Before filing Form 471, applicants should confirm:

• The Form 470 supports the requested services.
• The 28-day waiting period is complete.
• Any later bid deadline has passed.
• The service provider has been selected.
• A contract or legally binding agreement is in place where required.
• Costs, SPINs, recipients of service, and contract dates are accurate.
• Ineligible costs are removed or cost allocated.

The Form 471 deadline is not just a filing deadline. It is the endpoint of the competitive bidding and vendor selection process for that funding year.

Form 486 Deadline

The FCC Form 486 tells USAC that services have started and confirms CIPA compliance where required.

USAC states that Form 486 must be certified no later than:

• 120 days after the service start date, or
• 120 days after the date of the Funding Commitment Decision Letter,

whichever date is later.

Late Form 486 filing can reduce funding. USAC explains that the later the form is filed after the deadline, the greater the reduction can be.

For many recurring-service FRNs with a July 1 service start and an FCDL issued by or before July 1, the practical Form 486 deadline is often October 29. But applicants should not rely on a generic date. Form 486 deadlines depend on the FCDL date and the service start date for each FRN.

Applicants should file Form 486 after:

• The FCDL has been issued.
• Services have started or will start within the allowed early-filing rules.
• CIPA compliance can be certified, if CIPA applies.

Service providers should care about Form 486 too. For SPI invoicing, USAC requires Form 486 to be filed and successfully processed before the service provider can file FCC Form 474.

SPAC Deadline: FCC Form 473

SPAC stands for Service Provider Annual Certification. It is filed on FCC Form 473.

SPAC is a service provider deadline, but it can affect applicants because USAC cannot process and pay BEAR or SPI invoices for a funding year unless the provider has a SPAC on file for the relevant SPIN and funding year.

USAC states:

• Service providers can file SPAC after the Form 471 application filing window opens for the upcoming funding year.
• A SPAC must be on file before BEAR or SPI invoices can be processed and paid.
• USAC recommends filing no later than June 30 of the applicable funding year to allow time for reimbursement requests.

For providers, the practical rule is simple: do not wait until invoicing season to file SPAC. File it early, confirm the correct funding year and SPIN, and keep proof that it was filed.

For applicants, the practical rule is also simple: before invoice season, confirm that your service provider's SPAC is filed. A missing SPAC can delay payment even when the applicant's own forms are correct.

Last Day to Receive Service

Invoice deadlines depend on the last day to receive service, so applicants need to understand service delivery deadlines.

For recurring services, the service must be delivered during the funding year. A funding year runs July 1 through June 30.

For FY2027 recurring services:

• Funding year starts: July 1, 2027.
• Funding year ends: June 30, 2028.
• The last day to receive most recurring services is June 30, 2028.

For non-recurring services, USAC states that services generally must be delivered and installed between July 1 of the funding year and September 30 following the June 30 close of that funding year.

For FY2027 non-recurring services other than special construction:

• Service delivery generally starts no earlier than July 1, 2027.
• Service delivery generally ends September 30, 2028.

Special construction has a different rule. USAC states that special construction must generally be delivered and the network must be lit or in use by June 30 of the applicable funding year, unless an extension applies.

For FY2027 special construction:

• The general deadline is June 30, 2028.

Last Day to Invoice

The E-Rate invoice deadline is one of the most important deadlines in the program.

Applicants and service providers can invoice through:

• BEAR: FCC Form 472, filed by the applicant after paying the service provider in full.
• SPI: FCC Form 474, filed by the service provider after billing the applicant for the non-discount share.

USAC states that invoices must generally be submitted no later than the latest of:

• 120 days after the last day services are provided.
• 120 days after the FCC Form 486 Notification Letter date.
• 120 days after the date of a Revised Funding Commitment Decision Letter approving a post-commitment request or successful appeal of a previously denied or reduced funding request.

Applicant-facing USAC guidance often summarizes the deadline as 120 days after the last day to receive service or 120 days after the Form 486 Notification Letter date, whichever is later.

Common invoice dates:

• Recurring services ending June 30 usually have an invoice deadline of October 28.
• Non-recurring services ending September 30 usually have an invoice deadline of January 28 of the following year.

For FY2027, if no later Form 486 Notification Letter, RFCDL, appeal decision, or extension changes the deadline:

• Recurring services ending June 30, 2028 would commonly have an invoice deadline of October 28, 2028.
• Non-recurring services ending September 30, 2028 would commonly have an invoice deadline of January 28, 2029.

Do not rely only on the common dates. Applicants and service providers should check the invoice deadline for each FRN in EPC or USAC's invoice deadline tools.

Invoice Deadline Extensions

USAC allows one automatic 120-day invoice deadline extension for each FRN.

The extension request must be submitted on or before the invoice deadline. If the request is late, USAC cannot simply grant the extension through the normal process. The party must first seek a waiver from the FCC, and the FCC must grant the waiver before USAC can extend the deadline.

This is important because invoice extensions are not a safety net after a missed deadline. They are a pre-deadline tool. If there is a realistic chance the invoice will not be ready on time, request the extension before the deadline expires.

Applicants and service providers should request an extension when:

• The provider has not sent complete bills.
• Equipment delivery records are still being reconciled.
• Form 486 was processed late.
• An RFCDL or appeal changed the timeline.
• Internal finance approval will not finish before the deadline.
• The applicant and provider need more time to decide between BEAR and SPI.
• A post-commitment request is pending and the original invoice deadline is approaching.

For FY2016 and later FRNs, invoice deadline extension requests are filed in EPC. Applicants, consultants, and service providers can request extensions if they have the appropriate EPC rights. Service providers can file extension requests tied to FRNs under their SPIN, and applicants can file extension requests tied to their BEN.

Applicants and service providers should also understand what an invoice extension does not do:

• It does not extend the service delivery deadline.
• It does not make an ineligible product or service eligible.
• It does not replace a missing Form 486.
• It does not fix an unfiled SPAC.
• It does not waive a missed Form 471 filing window.
• It does not allow invoicing for products or services that were never delivered.

An invoice deadline extension only gives more time to submit the BEAR or SPI invoice.

Service Delivery Deadline Extensions

Service delivery deadline extensions are different from invoice deadline extensions.

USAC states that recurring services must be delivered during the funding year and that there are no extensions for the installation deadline for recurring services.

For non-recurring services, the general delivery and installation deadline is September 30 following the close of the funding year. Certain extensions are automatic, and others must be requested through FCC Form 500 on or before the last date to receive service.

Applicants should request service delivery extensions when eligible non-recurring services or equipment cannot be delivered and installed by the deadline for reasons allowed under E-Rate rules.

USAC identifies several circumstances where non-recurring service delivery deadlines may be extended:

• USAC issues the FCDL on or after March 1 of the funding year for which support is authorized.
• USAC approves an operational SPIN change or service substitution on or after March 1 of the funding year.
• The service provider cannot complete delivery and installation for reasons beyond the service provider's control.
• The service provider has been unwilling to complete delivery and installation after USAC delayed payment while reviewing the application for program compliance.

USAC says the first two situations are automatic. For the other situations, recipients of non-recurring services other than special construction must file FCC Form 500 on or before the last date to receive service, generally September 30 following the close of the funding year.

For FY2027 non-recurring services other than special construction, the general service delivery deadline is September 30, 2028. If the applicant needs a non-automatic extension, the Form 500 request should be filed on or before that deadline.

Special construction is different. Special construction must generally be completed and the network must be lit or in use by June 30 of the applicable funding year. Applicants may receive a one-year extension if they can demonstrate that construction was unavoidably delayed due to weather or other reasons. If FY2027 special construction cannot be completed, lit, or in use by June 30, 2028, the applicant should file FCC Form 500 on or before June 30, 2028.

Do not confuse these two deadlines:

• Service delivery extension: more time to receive/install the service or equipment.
• Invoice deadline extension: more time to submit BEAR or SPI invoices after service delivery.

FCC Form 500 Deadline Changes

FCC Form 500 is the form applicants use for several post-commitment changes. It can be used to:

• Request a service delivery extension for non-recurring services.
• Change the contract expiration date listed on Form 471.
• Adjust the funding year service start date reported on Form 486.
• Cancel an FRN.
• Reduce the amount of an FRN.
• Request an invoicing mode change after an FCDL has been issued, beginning in FY2026.

Form 500 cannot be filed until USAC has issued an FCDL for the FRN.

The deadline depends on the change being requested. For service delivery extensions that are not automatic, applicants should file by the service delivery deadline. For contract expiration date changes, applicants should update the contract record before relying on the changed contract date for later activity. For reductions or cancellations, applicants should file as soon as they know the funds will not be used.

What E-Rate Deadlines Can Be Extended?

Not every E-Rate deadline works the same way.

Deadlines that commonly have a USAC extension path:

• Invoice deadline: one automatic 120-day extension per FRN if requested on or before the invoice deadline.
• Non-recurring service delivery deadline: extension may be automatic or requested through Form 500, depending on the reason.
• Special construction delivery deadline: one-year extension may be available if construction was unavoidably delayed and the request is filed on time.

Deadlines that usually require FCC waiver relief if missed:

• Form 471 filing window.
• Late invoice extension request.
• Missed appeal or waiver deadline.
• Missed service delivery extension request deadline.

Deadlines that generally are not extended through the same process:

• Recurring service delivery must occur within the funding year.
• Form 486 late filing is handled through service start date adjustment and funding reduction, unless separate waiver relief applies.
• SPAC does not extend the applicant's invoice deadline; it must be filed so payments can be processed.

Appeals and Waiver Deadlines

Appeals are another important E-Rate deadline category.

Applicants and service providers generally must appeal a USAC decision within 60 days of the decision. Appeals can relate to funding denials, invoice reductions, post-commitment decisions, or other USAC actions.

Appeals should be filed as soon as the issue is understood. Waiting until the end of the 60-day period increases the risk of missing information, unclear facts, or internal approval delays.

Waivers are different from ordinary appeals. USAC can decide appeals, but USAC cannot waive FCC rules. If the issue requires waiver of a program rule, such as a missed Form 471 filing window or a missed invoice deadline extension request, the waiver request must go to the FCC.

The practical rule is:

• Appeal a USAC decision to USAC within 60 days.
• If you need waiver of an FCC rule, file with the FCC.
• If USAC denies an appeal and you disagree, appeal to the FCC within 60 days of USAC's decision.
• If an FCC waiver is denied, a petition for reconsideration is generally due within 30 days of the FCC decision.

• Contract execution and service start dates.
• SPAC Form 473 filing status for each SPIN and funding year.
• Form 486 processing status before SPI invoicing.
• Applicant non-discount share billing.
• Service delivery dates.

• Document retention period.

Common E-Rate Deadline Mistakes

Common mistakes include:

• Waiting until the last possible Form 470 date.
• Forgetting that a later RFP bid deadline can control the award date.
• Filing Form 471 before the allowable contract date.
• Assuming FY2027 dates are final before USAC announces them.
• Missing Form 486 because the FCDL arrived during summer.
• Trying to file SPI before Form 486 is processed.
• Forgetting that SPAC is required before BEAR or SPI payment.
• Treating October 28 and January 28 as universal invoice deadlines.
• Missing the invoice extension request deadline.
• Confusing service delivery extensions with invoice extensions.
• Assuming a service delivery extension automatically extends the invoice deadline.
• Assuming an invoice extension gives more time to install equipment.
• Forgetting to file Form 500 for non-automatic service delivery extensions.
• Waiting for a pending SPIN change, service substitution, or appeal while the invoice deadline continues to approach.
• Not tracking deadlines by FRN.

E-Rate Deadline Checklist

Use this checklist every funding year:

• Confirm the official USAC filing window dates.
• Build a deadline calendar by funding year and FRN.
• File Form 470 early enough to allow real procurement time.
• Track the 28-day allowable contract date.
• Track any later RFP bid deadline.
• Certify Form 471 before the filing window closes.
• Record the FCDL date for every FRN.
• Record the service start date for every FRN.
• File Form 486 by the correct FRN-specific deadline.
• Confirm SPAC status for every service provider and funding year.
• Track last day to receive service.
• Track service delivery extension needs before the service delivery deadline.
• File Form 500 on time when a service delivery extension is not automatic.
• Reconcile invoices monthly or quarterly.
• File BEAR or SPI before the invoice deadline.
• Request invoice deadline extensions before the deadline expires.
• If a deadline was already missed, evaluate whether an FCC waiver is needed.

Informational only, not legal advice. E-Rate deadlines, filing windows, and EPC procedures change over time, and many dates depend on each FRN. Confirm every date against current USAC guidance and the official FCC rules before relying on it.
