If you sell to the federal government — or want to — there's a rhythm to the year you need to know. Federal spending isn't spread evenly across the calendar. It surges dramatically in the final months of the government's fiscal year, and small businesses who understand this can time their efforts to catch the wave. Here's how the federal fiscal year works and why the last quarter matters so much.
The federal fiscal year, in plain English
The federal government's fiscal year runs from October 1 to September 30 — not January to December. So "the fourth quarter" of the government's year is July, August, and September, ending on September 30.
This matters because of how agency budgets work: agencies receive funding for the year, and in many cases, money that isn't spent (obligated) by September 30 can be lost. That creates a strong, predictable incentive to spend remaining funds before the deadline.
Why Q4 (July–September) is the busy season
As September 30 approaches, agencies rush to obligate their remaining budgets. The practical effects for contractors:
- A surge of opportunities. More solicitations get posted, and more contracts get awarded, in the final weeks than at almost any other time.
- Use-it-or-lose-it urgency. Agencies are motivated to get money out the door, which can mean faster decisions and more willingness to buy.
- More small-dollar and simplified buys. A lot of year-end spending is in smaller amounts that suit small businesses, often through quick, simplified purchases.
- Opportunity for the prepared. Firms that are already registered, known to the agency, and ready to respond fast are positioned to capture work others miss in the scramble.
For a small business, the run-up to September 30 can be the single best window of the year to win federal work — *if* you're ready before it starts.
How to prepare for year-end spending
The key word is *prepared.* Year-end moves fast; you can't start from scratch in September. Get ready in advance:
1. Be registered well before Q4. Make sure your SAM.gov registration is active and current — don't let it lapse heading into the busy season. (SAM.gov registration guide.)
2. Have your capability statement and pricing ready. When an agency needs to buy quickly, the firm that responds immediately with clear information wins. (Capability statement template.)
3. Build agency awareness early. Reach out to agency small-business offices in the spring and summer so they know you when year-end buying starts. (How to research an agency.)
4. Watch for opportunities daily in Q4. The volume spikes, so missing postings is easy. Set yourself up to catch every relevant one. (Never miss a deadline.)
5. Be ready to move fast. Year-end timelines are tight. Decide quickly which opportunities fit, and respond promptly and correctly.
A balanced perspective
Year-end is a real and valuable surge, but two honest caveats:
- It's not the only time to win. Agencies buy all year, and recurring contracts are awarded on their own schedules. Don't ignore the other nine months.
- The rush can mean more competition too. Everyone knows about year-end. Your edge comes from being prepared, known, and responsive — not just from showing up in September.
Think of Q4 as the moment your year-round groundwork pays off: if you're registered, known, and ready, the year-end surge is when that preparation converts into wins.
The bottom line
The federal fiscal year ends September 30, and agencies spend heavily in the final quarter (July–September) to use their remaining budgets before the deadline. For small businesses, that's a predictable annual surge of opportunities — especially smaller, faster buys that suit small firms. The firms that benefit are the ones already registered, known to the agency, and ready to respond fast. Prepare in the spring and summer so you can capture the wave when it comes.
Frequently asked questions
When does the federal fiscal year end?
September 30. The federal fiscal year runs October 1 through September 30, so the government's fourth quarter is July, August, and September.
Why does the government spend so much at the end of the fiscal year?
Agencies are funded for the year, and unspent money can be lost after September 30. That use-it-or-lose-it dynamic motivates them to obligate remaining funds before the deadline, creating a surge of contracts.
Is year-end a good time for small businesses to win contracts?
Yes — it's often the busiest window, with more opportunities and more small-dollar, simplified buys that suit small firms. But you must be registered and ready in advance to capture it.
How do I prepare for federal year-end spending?
Keep your SAM.gov registration current, have your capability statement and pricing ready, build agency relationships in spring and summer, and watch postings closely in July–September so you can respond fast.
