Government Fiscal Year Calendar

The federal government fiscal year (FY) runs from October 1 through September 30, establishing a 12-month budget and spending cycle that drives predictable patterns in procurement activity, contract awards, and agency purchasing behavior that government contractors must understand and plan around.

What is the Government Fiscal Year Calendar?

Unlike most businesses that operate on a January-to-December calendar year, the U.S. federal government's fiscal year begins on October 1 and ends on September 30. Congress appropriates funds for each fiscal year, and those funds carry specific obligation windows, the period during which they can be legally committed to contracts.

The fiscal year creates distinct procurement seasons. The first quarter (Q1: October-December) is typically slow as agencies absorb new appropriations and adjust spending plans. The second and third quarters (Q2-Q3: January-June) see steady contracting activity as agencies work through their procurement pipelines. The fourth quarter (Q4: July-September) is historically the most active, as agencies must obligate remaining funds before the fiscal year ends or risk losing unspent appropriations, a phenomenon known as the fourth quarter spending surge.

Understanding the government fiscal year calendar is foundational to GovCon capture planning. Agencies publish procurement forecasts anchored to the fiscal year calendar. Solicitations released in Q3 often have proposal due dates in Q4. Recompetes are typically planned to award before the current contract's fiscal year funding expires. Agency budget cycles, from the President's Budget Request in February through Congressional action to final appropriations, also affect when procurement authority is available.

Why the government fiscal year calendar matters for government contractors

Aligning capture activity, proposal resources, and staffing to the government's fiscal year cycle is a core business development discipline. Companies that front-load their pipeline development in Q1 and Q2, engaging customers early, responding to RFIs, attending industry days, are better positioned for Q4 awards than companies that react to solicitations as they appear.

Example

A federal IT services firm analyzes its contract awards over five years and finds that 43% of its contract dollars were awarded in Q4 (July-September). It restructures its proposal resource plan to maintain maximum writer availability from June through September and conducts its major customer engagement efforts from January through May, when program managers are finalizing requirements for upcoming Q4 solicitations.

Frequently Asked Questions

Why does the federal fiscal year start in October rather than January?

The October 1 start date was established by the Congressional Budget Act of 1974. Congress changed the fiscal year from a July 1-June 30 cycle to October 1-September 30 to give itself more time to complete the annual budget process before funds were needed.

What happens if Congress has not passed appropriations by October 1?

When appropriations are not enacted by October 1, the government operates under a Continuing Resolution (CR), which typically funds agencies at the prior year's spending rate. CRs create uncertainty in procurement planning because they limit agencies' ability to start new contracts or increase spending above prior-year levels.

Do all federal agencies follow the same fiscal year?

All executive branch agencies follow the October 1-September 30 fiscal year. Congress itself operates on the same calendar for budget purposes. The Federal Reserve and a handful of independent entities may use different fiscal years, but for contracting purposes the October-September cycle is universal across federal procurement.

How should contractors plan for the fourth quarter spending surge?

Contractors should maintain available proposal resources in Q4, monitor agency procurement forecasts for anticipated Q4 awards, and identify existing contract vehicles (IDIQs, BPAs, GSA schedules) through which the agency can place orders quickly before fiscal year-end. Being an approved vendor on a contract vehicle before Q4 is the most effective strategy for capturing year-end spending.
