Federal Fiscal Year Explained (and Why September Matters)

The federal fiscal year is the 12-month period the U.S. government uses for budgeting and financial reporting. It runs from October 1 through September 30, so September is the final month of the year.

September can matter because some agencies work to place eligible purchases before certain funds expire or become unavailable for new obligations. That can create activity, but it does not guarantee a contract, a faster award, or a good opportunity for your business.

Federal fiscal year dates

A federal fiscal year is named for the calendar year in which it ends. For example, federal fiscal year 2026, often written FY2026, ran from October 1, 2025, through September 30, 2026. The next fiscal year began on October 1, 2026.

The government uses fiscal years to organize budgets, spending plans, and financial records. A fiscal year is not the same as a calendar year, which runs from January through December. A company may also use its own financial year, so do not assume a customer or subcontracting partner follows the federal schedule unless you have confirmed it.

Why the government fiscal year end matters

September 30 is the government fiscal year end. It can be a busy period for some contracting offices because they may be trying to complete purchases using funds with a limited period of availability. The timing and rules vary by funding source, agency, and purchase.

The important contracting term is obligation. An agency generally needs to take a valid action to commit funds to a purchase. That is different from paying an invoice. A solicitation posted in September may not lead to an award before September 30, and an award near the end of the year does not mean the contractor will be paid immediately.

Some funds may be available for longer than one fiscal year, while others have different restrictions. An agency cannot use funds for any purchase simply because the year is ending. The purchase must be permitted by the funding and procurement rules, and the agency must follow the solicitation and award process.

What use or lose spending in September really means

Contractors often use the phrase “use or lose” to describe year-end spending pressure. It is shorthand, not a promise that an agency must spend every dollar or will rush to award any available bid. Funds that are not committed may be handled under the rules for that appropriation, and those rules can differ.

For a small business, the practical takeaway is to watch for real solicitations and respond only when the scope, schedule, and terms make sense. A short response window or a September due date is not a reason to skip your normal checks. Read the full solicitation, confirm that you can meet the requirements, and account for the time needed to perform.

If a notice is unclear about funding, performance dates, or the award schedule, use the solicitation’s stated question process to ask the contracting office. Do not assume that a September posting means the agency has already selected a contractor or that the work will begin immediately.

• Check the notice for the response deadline, contract start date, period of performance, and funding information.
• Confirm that the requested work fits your capacity and that you can meet every material requirement.
• Base your price and staffing plan on the contract terms, not on an assumption that the agency needs to spend quickly.

How the fiscal calendar affects small businesses

The federal fiscal calendar can help you plan when to research buyers and keep proposal materials ready. It should not be your only timing strategy. Agencies buy throughout the year, and purchase schedules depend on their needs, funding, approvals, and acquisition plans.

Start by identifying agencies that buy your type of work and the locations you can serve. Browse federal agencies and what they buy, and review federal contract spending by state or federal contract spending by industry to develop a research starting point. Spending history can show where to investigate, but it does not predict a future award.

Use the right industry classification when searching. NAICS codes are six-digit industry codes, and the Small Business Administration sets a size standard for each NAICS code. You can use the free NAICS code lookup, then check current size standards at SBA.gov.

Prepare before September

Waiting until September to look for work can leave too little time to understand a requirement, ask questions, build a team, and prepare a complete response. Keep a regular search routine during the year. Save notices that fit your business and track any stated changes to deadlines or requirements.

You can find federal contract opportunities in the Contract Opportunities section of SAM.gov. Registration at SAM.gov is free, and a business must complete a full SAM registration to bid on federal prime contracts. Do not pay a third party just to register. For help with SAM.gov itself, contact the Federal Service Desk.

1. Choose the work you can deliver, the places you can serve, and the NAICS codes that fit your services.
2. Search for notices throughout the year. Review the full solicitation and note the response deadline, required documents, and any site visit or question deadline.
3. Research prior awards and agency buying patterns, then use that information to decide which opportunities deserve a closer look.
4. Keep your registration, insurance information, pricing assumptions, and proposal materials current so you can respond when a suitable notice appears.

Research awards and agency buying

Past awards can help you understand the kinds of work an agency buys, who has performed it, and whether similar work appears repeatedly. Search award records on USAspending.gov, and compare what you find with current solicitations. An old award is background research, not a forecast or a guarantee that the work will be competed again.

You can also review federal contractors ranked by contract dollars as a starting point for learning about incumbent firms and potential teaming partners. Look for patterns in the work and customer, but check the underlying award details before drawing conclusions. Contract amounts and timing can reflect multiple years, options, or other terms.

For active bids, check open federal bids and read each solicitation in full. A search result or summary is not a substitute for the actual notice and its attachments. Follow the solicitation for submission instructions, questions, deadlines, and any amendments.

September is not a payment deadline

The end of the federal fiscal year concerns budgeting and the obligation of funds. Contractor payment follows the contract’s payment terms and the agency’s invoice and acceptance process. A September award does not automatically mean you will receive payment by September 30.

Before you bid, check how the contract handles invoicing, deliverables, acceptance, and payment. Make sure your business can cover payroll, materials, and other costs while work is underway. If you are unsure how a payment clause applies, ask the contracting office before submitting your offer or seek qualified business or legal advice.

Plan around the work and written contract terms, not a general belief that agencies spend faster or pay faster at year end. A well-matched opportunity at another time of year may be a better fit than a rushed bid in September.

Frequently asked questions

How do I find government contracts to bid on?

Search the Contract Opportunities section of SAM.gov and filter for work that matches your services, location, and capabilities. Read each solicitation and its attachments for eligibility, deadlines, and submission rules. You can also use open federal bids to explore opportunities.

How do government contractors get paid?

Payment depends on the contract terms, the work or deliverables required, and the agency’s invoice and acceptance process. Follow the contract’s instructions for submitting invoices and supporting documents. Do not assume an award near September 30 means payment by that date.

How much money can you make from government contracts?

There is no standard amount a contractor earns. Revenue depends on the contract’s scope, price, duration, costs, competition, and your ability to perform profitably. Review similar past awards for context, but do not treat award amounts as a promise of future revenue.

What is the government fiscal year end?

The federal government fiscal year ends on September 30 and begins on October 1. The year is named for the calendar year in which it ends. State and local governments, agencies, and private businesses may follow different fiscal calendars.

Does use or lose spending in September guarantee more contracts?

No. The phrase describes possible pressure to commit eligible funds before their period of availability ends, but it does not require an agency to award every purchase or guarantee that a solicitation will appear. Focus on opportunities you can perform and follow the stated procurement process.
