We want a different fiscal year and a different accounting method. Does one filing approve both?
Changing the annual accounting period and changing an accounting method are distinct tax procedures.

Changing the annual accounting period and changing an accounting method are distinct tax procedures. Form 1128 or an applicable tax-year procedure does not automatically approve a cash-to-accrual or other method change, and Form 3115 does not by itself authorize a new fiscal year. Each change needs its own eligibility analysis.
A specific business-owner situation
A corporation wants a June year-end and a different inventory method in the same project. One software conversion date cannot establish that both federal procedures were completed.
Illustrative example, not a client result.
What to establish before filing
- Identify the annual-period change.
- Identify each separate accounting-method change.
- Review consent procedures adjustments and effective dates independently.
Which fact changes the answer?
A financial-reporting change may require neither tax change, while an intended tax change can require one or both procedures. Define the actual objectives first.
A mistake to avoid
Do not use the phrase accounting change as though it describes one universal filing.
Records that support the decision
- Prior returns.
- Tax-year application or election.
- Method-change and adjustment schedules.
The decision to document
Create a coordinated implementation calendar that identifies the authority and filing for each separate change.
