The practical answer
Build separate calendar entries for IRS filing, the chosen furnishing method, request responses and states, then work backward through coverage-data readiness.
A coverage provider's 1095-B calendar needs both an annual filing schedule and, when used, a continuing recipient-request workflow. This guide uses the verified 2025 reporting cycle as a dated example. The latest final B-series instructions reviewed on September 5, 2026 remain labeled 2025, so next-cycle dates are verification fields.
Start with the reporting entity and coverage year
Identify the insurer, government program or other provider responsible for the B-series population. Record coverage year, covered-individual population and the responsible-individual statement population separately. A single responsible individual can have several covered family members on the statement, so member counts and return counts are different controls.
Use the 1094-B/1095-B instructions to confirm the reporting route. An applicable large employer's self-insured employee coverage generally belongs in 1095-C Part III, while other coverage providers can use the B series. Resolve scope before scheduling a file. This calendar does not determine coverage classifications or replace a form-completion review.
Use the verified 2025 cycle as a dated reference
The final B-series instructions currently reviewed identify tax year 2025. They explicitly give March 2, 2026 for paper IRS filing and March 31, 2026 for electronic IRS filing. Direct furnishing generally had a March 2, 2026 date. These are historical reporting-cycle dates, not projected deadlines for 2026 coverage.
For the next cycle, retain the same calendar structure and verify dates against its official instructions when available. Record authority, source year and checked date. The choice of paper must also be permitted under the applicable electronic-filing rules, which consider aggregated information-return counts. A later electronic date does not make the recipient or state schedule disappear.
Schedule the chosen furnishing method
Notice 2025-15 permits a qualifying notice-and-request method for coverage statements for calendar years after 2023. It requires a clear, conspicuous and accessible website notice posted by the furnishing due date, including the automatic extension, and retained through October 15 of the filing year. The applicable notice must explain how to request a statement and provide the required contact information.
Requested statements must be furnished by the later of January 31 following the coverage year or 30 days after the request. Track the website obligation and each request separately. This method changes how furnishing can be satisfied; it does not remove IRS filing. Direct furnishing remains another operational route.
Compare the tasks in a fictional provider calendar
A fictional coverage provider uses electronic IRS filing and the qualifying notice-and-request method for 2025 statements. Its calendar must contain more than one March deadline. The table uses the dates expressly supported by the 2025 instructions and Notice 2025-15.
| Obligation | Verified timing | Completion evidence |
|---|---|---|
| Website notice | Post by March 2, 2026 | Dated notice and publication record |
| IRS electronic filing | March 31, 2026 | Actual acknowledgment and outcome |
| Notice availability | Through October 15, 2026 | Availability and change history |
| Individual request | Applicable later-of rule | Request and furnishing timestamps |
State obligations remain separate entries requiring the relevant state authority. A federal website notice is not evidence that a state filing or furnishing requirement was met.
Work backward through coverage feeds and review
Set internal dates for eligibility-feed receipt, coverage-month reconciliation, responsible-individual cleanup, form review and provider release. Identify retroactive enrollment and termination changes, which can arrive after a routine feed. Schedule an explicit decision on which version belongs in the original release and which changes require later correction.
Assign both a primary and backup owner for the request inbox and mailing address. A notice can be technically online while no one monitors its channels. Verify statement-production capacity before posting. Keep internal targets distinct from official dates and document vendor cutoffs so a missed feed can be escalated while useful repair time remains.
Schedule a handoff check between the coverage administrator and the filing provider: confirm accepted input version, expected return count and who retrieves the IRS result. A vendor's source-file deadline is not the same event as IRS submission. Put both dates in the calendar and require evidence for each.
Track extensions and completion with separate evidence
The B-series instructions describe a timely Form 8809 filing-extension process. Verify the current application instructions and submission channel before execution, especially when planning beyond the historical cycle. A filing extension does not automatically alter the furnishing method or request-response deadline.
Close each calendar entry with the actual artifact: approved data release, IRS acknowledgment, notice publication record or furnished statement. Keep later errors and recipient requests visible after the main filing date. At year rollover, reverify the source year, method, state obligations and notice text. Do not carry the older 2024 dates embedded in parts of the 2025 instructions into the new schedule.
The B-series provider calendar
Read the workflow as text
- Scope. Identify provider, coverage year and statement population.
- Schedule. Verify IRS, furnishing-method and state dates.
- Prepare. Reconcile coverage feeds and release reviewed data.
- Maintain. Retain notice availability, request service and filing outcomes.

Are the displayed 2026 dates for 2026 coverage?
No. They are the official filing-year dates for 2025 coverage. The guide labels that historical cycle expressly. Verify the next coverage year's final instructions before populating its operating calendar.
Does the website notice replace IRS filing?
No. The qualifying alternative method concerns furnishing statements to individuals. The provider still needs to satisfy its IRS reporting obligation and independently determine applicable state requirements.
Can I use the old notice dates in the B instructions?
The reviewed 2025 page retains some older-cycle language. Use its explicit 2025 provisions together with Notice 2025-15 and record the reporting year. Do not copy a date without checking which cycle it describes.
Does every covered family member create a separate return?
Not necessarily. The B-series statement can include multiple covered individuals associated with a responsible individual. Maintain member and return counts separately and resolve the form population under the instructions.
Does Form 8809 extend request-response timing?
Do not assume that. The filing-extension process concerns IRS returns. Keep furnishing-method and individual-request requirements separate, and verify the actual effect of any applicable relief.
