Fiscal Year
Fiscal Year is the Salesforce setting that defines the period over which the org tracks revenue, quotas, and forecasting.
Definition
Fiscal Year is the Salesforce setting that defines the period over which the org tracks revenue, quotas, and forecasting. Two configurations exist: Standard Fiscal Year follows the calendar (January through December) with the start month configurable, while Custom Fiscal Year lets an organization define its own period structure (4-4-5 retail calendar, 13 periods, fiscal year starting in any month with non-standard quarter alignments). The choice cascades through every revenue-related feature: Opportunity Close Date interpretation, Forecast tabs, Quota allocation, and most Sales Cloud reports that aggregate by period.
The setting is org-wide and changes are not casual. Switching from Standard to Custom Fiscal Year, or changing the start month, recalculates every Opportunity's fiscal period assignment, breaks every report grouped by fiscal year or quarter, and resets in-flight forecasts. Salesforce requires explicit confirmation before applying the change and provides limited rollback options. Most orgs configure Fiscal Year during initial implementation and rarely revisit it; mid-life changes happen only during a major business event (acquisition, business model shift) and warrant a dedicated migration project.
How Fiscal Year shapes Salesforce reporting
Standard versus Custom Fiscal Year
Standard Fiscal Year is the simpler option. Pick a start month; quarters are three months each; year boundaries follow the calendar with the offset you chose. Most B2B SaaS companies use February as the start to align with a February-January fiscal year. Custom Fiscal Year is for retail, manufacturing, and other industries where the fiscal calendar deviates from the standard quarter structure: 4-4-5 weeks per period, 13 four-week periods, or other non-standard layouts. Once set to Custom, the org cannot revert to Standard without Salesforce support intervention.
Where the setting matters
Fiscal Year affects every place period names appear: Opportunity close-date period labels, Forecast tab columns, Quota records, Activity Timeline date filters, and reports grouped by quarter or year. Custom Fiscal Year customers see period names defined in their Custom configuration (P1 2026, Q1 2026, etc.) rather than calendar quarter names. Reports built before a fiscal year change need rebuilding because the period grouping changes.
Configuring Standard Fiscal Year
Setup > Company Settings > Fiscal Year > Standard > pick Start Month. The change is immediate. All Opportunities, Quotas, and reports recompute their period assignments. The setting also lets you choose whether the fiscal year is named for the year it starts in or the year it ends in (a 2026 fiscal year starting February 2025 can be called "FY2025" or "FY2026" depending on convention).
Configuring Custom Fiscal Year
Custom Fiscal Year requires more setup. Configure the start month, then define the structure for each fiscal year: number of quarters, length of each period, weeks per quarter. The platform supports several preset templates (4-4-5, 4-5-4, 5-4-4, 13 periods of 4 weeks), or fully custom configurations defined week-by-week. Once defined, fiscal years must be created in advance; the org cannot save records dated to a fiscal year not yet defined.
Impact on Opportunities and Forecasts
Every Opportunity has a CloseDate, and the platform derives the FiscalQuarter and FiscalYear fields from that date based on the fiscal year configuration. Changing the configuration recomputes these derived fields, which means historical reports grouped by FiscalQuarter shift their numbers. Forecasts also reset; quarterly forecast snapshots taken before the change do not retroactively apply the new period structure. Plan the transition carefully if mid-year.
Limitations to know
Once an org enables Custom Fiscal Year, reverting to Standard requires a Salesforce support case and effectively a manual reconfiguration. Custom Fiscal Year also disables some reporting features that depend on calendar quarters; check each report your team relies on against the Custom Fiscal Year compatibility list before switching. Some advanced Forecasting features have additional configuration considerations under Custom.
Creating future fiscal years under Custom
Custom Fiscal Year requires you to define each upcoming year in advance; the platform does not auto-roll the configuration. Plan a quarterly or annual review to define the next fiscal year before any records can be saved with dates in that period. Missing this step produces a runtime error when a user tries to save a future-dated Opportunity. Add the definition cycle to your sales-ops calendar.
Configure Fiscal Year
Setting Fiscal Year is a one-time configuration for most orgs. The steps below cover the safe approach for initial setup and the rare mid-life change.
- Confirm business requirement
Work with finance to confirm the fiscal year structure. Standard handles 95% of B2B SaaS; Custom is needed for retail, manufacturing, or non-standard calendars.
- Open Fiscal Year Setup
Setup > Company Settings > Fiscal Year. The page shows the current configuration.
- Pick Standard with a start month
Select Standard Fiscal Year, choose the start month (January for calendar year; February for many B2B SaaS; April for many UK companies; July for many APAC companies).
- Or pick Custom and define structure
Select Custom Fiscal Year, pick a preset (4-4-5, 4-5-4, 13 periods) or define week-by-week. Define the upcoming fiscal year boundaries.
- Save and confirm
Save. The platform prompts to confirm; the change is broad. After confirmation, period assignments recompute across all records.
- Audit reports and forecasts
Rebuild any reports grouped by fiscal period. Re-run forecasts to refresh against the new structure. Confirm Opportunity period fields show expected values.
- Define future fiscal years (Custom only)
For Custom, define the next 2-3 fiscal years immediately so future-dated Opportunities save without errors.
Default. Calendar quarters with configurable start month.
Non-standard structure for retail, manufacturing, or unique calendars.
Configurable for Standard. The month the fiscal year begins.
Whether FY2026 starts in 2025 or 2026 (start-year vs end-year).
Preset 4-4-5, 4-5-4, 5-4-4, or 13 four-week period structures for Custom.
- Custom Fiscal Year is one-way without a Salesforce support case. Confirm long-term need before enabling.
- Changing fiscal configuration recomputes every Opportunity period assignment. Historical reports shift numbers.
- Custom Fiscal Year requires future years to be defined in advance. Missing definitions cause save errors on future-dated records.
- Some Forecasting features and reports have limited support under Custom. Audit dependencies before switching.
- Fiscal Year change is org-wide. Cannot be set per business unit; multi-business-unit orgs typically pick one calendar and adapt.
