SBA Size Standards Overhaul Opens New Funding Paths for Medical Billing Startups

What Does the 2026 SBA Size Standards Proposal Mean for Medical Billing Businesses?

As of August 2026, the U.S. Small Business Administration has proposed the largest rewrite of its small business size standards in decades, consolidating nearly 1,000 industry categories into 338 broader classifications and raising eligibility thresholds across most sectors. For aspiring medical billing business owners, this proposed rule expands access to SBA-backed loans, microloans, and federal small business programs by allowing growing companies to retain their small business status longer, making it easier to fund a billing startup or scale an existing operation with government-backed capital.

• Over 114,000 firms added: The SBA estimates this proposal would add more than 114,000 businesses to small business eligibility nationwide, opening access to 7(a) loans, microloans, and federal contracting set-asides.
• Simplified classification: The current system of nearly 1,000 NAICS-based size standards drops to 338 broader industry groups, reducing confusion for new business owners trying to determine their eligibility.
• Comments due September 21, 2026: This is a proposed rule, not a final regulation. Business owners and industry groups can submit public comments through the Federal eRulemaking Portal before the deadline.

What the SBA Actually Changed

On August 20, 2026, the SBA published two concurrent notices of proposed rulemaking in the Federal Register. The first introduces a revised methodology for calculating size standards. The second applies that methodology to propose new thresholds across 338 industry groups, replacing the previous system of nearly 1,000 separate standards tied to six-digit NAICS codes.

The practical effect is that size thresholds increase across most industries. In professional services, IT, and healthcare support sectors, some thresholds rise substantially. The SBA also proposes shifting several sectors from receipts-based standards to employee-based standards, which changes how companies measure eligibility.

For context, size standards determine whether a company qualifies as a “small business” under federal law. That classification controls access to SBA 7(a) loans, SBA microloans (up to $50,000), Community Advantage loans, the 8(a) business development program, federal contracting set-asides, and SBA-affiliated counseling through Small Business Development Centers and Women’s Business Centers. Losing small business status means losing access to all of those programs.

The key numbers from the proposal: the SBA estimates approximately 114,541 employer firms would gain small business status, while fewer than 200 would lose it. Comments on both proposed rules are due September 21, 2026, and no new standards take effect until a final rule is published.

Who Qualifies Under the New Size Standards?

Under the current system, a medical billing business falls under NAICS code 561110 (Office Administrative Services) or 524292 (Third Party Administration of Insurance and Pension Funds), depending on how the company structures its services. The existing receipts-based size standard for NAICS 561110 is $15 million in average annual receipts, meaning a billing company generating less than $15 million in annual revenue qualifies as small.

Under the proposed rule, thresholds for professional and administrative services categories are expected to increase. The consolidation from six-digit to four- and five-digit NAICS levels means fewer separate standards and simpler eligibility checks. A billing company that starts small and grows past the current threshold would have more room before losing access to SBA programs under the proposed structure.

For someone starting a medical billing business from home, the immediate takeaway is straightforward: you are well within small business eligibility under both the current and proposed standards. The change matters more as you scale. A billing company that grows from a solo operation into a multi-employee firm billing $2 million to $5 million annually stays classified as small with a wider margin, keeping SBA loan access available during the growth phase when capital is most needed.

The broader effect is that more companies across healthcare services, professional services, and administrative support now qualify for SBA programs, which increases competition for those programs but also signals that the SBA is prioritizing access for growing firms rather than capping eligibility at lower revenue levels.

Why the Timing Matters for Billing Startups

The U.S. medical billing outsourcing market is projected to grow from $7.24 billion in 2026 to $21.41 billion by 2035, according to Towards Healthcare. That growth rate, combined with the SBA’s expanded eligibility proposal, creates a two-sided opening. On one side, providers are outsourcing billing at higher rates because of rising claim denial rates, regulatory complexity, and staffing shortages. The denial crisis alone is pushing practices toward third-party billing partners faster than at any point in the last decade.

On the other side, the SBA is making it easier for new and growing businesses to access startup capital. An SBA microloan of $10,000 to $50,000 can cover the cost of a billing training program, practice management software, a clearinghouse subscription, initial marketing, and the first few months of operating expenses before client revenue stabilizes. The SBA 7(a) loan program, which offers loans up to $5 million, provides additional runway for billing companies ready to hire staff or invest in automation.

We see this pattern regularly at Medical Billing Opportunity. People who are ready to start a billing business often have the drive, the time, and the interest, but the upfront investment creates hesitation. Knowing that SBA-backed financing exists specifically for small service businesses, and that the government is actively expanding eligibility rather than restricting it, removes one of the biggest barriers to entry.

How Can You Use SBA Programs to Fund a Medical Billing Business?

SBA financing is not a single product. It is a set of programs with different loan sizes, terms, and use cases. Here is how each one applies to a medical billing startup:

1. Apply for an SBA microloan through a local intermediary lender. SBA microloans range from $500 to $50,000 and are designed for startups and small businesses that need working capital, equipment, or training costs. A billing startup can use a microloan to cover a training program like Medical Billing University, practice management software, and initial marketing spend.
2. Explore the SBA 7(a) loan program for larger capital needs. The 7(a) program offers loans up to $5 million with terms up to 25 years. For a billing business scaling beyond the solo operator phase, this funds hiring, technology infrastructure, and working capital during the growth period when receivables lag behind expenses.
3. Check eligibility at your local Small Business Development Center. SBDCs offer free, confidential business advising and can help you prepare a loan application, build a business plan, and identify which SBA program fits your situation.
4. Register your business and obtain your NAICS code. SBA eligibility is tied to your NAICS classification. Ensure your business registration reflects the correct code (typically 561110 for office administrative services or 524292 for third-party administration) before applying.
5. Prepare a lean business plan with realistic revenue projections. SBA lenders want to see that your business model is viable. A billing company that can demonstrate recurring revenue potential, low overhead, and a clear client acquisition strategy has a strong application. Our full income breakdown provides the revenue benchmarks lenders look for.
6. Submit your comment on the proposed rule before September 21, 2026. If you believe the expanded size standards benefit small healthcare service businesses, the SBA is accepting public comments through the Federal eRulemaking Portal at regulations.gov under Docket No. SBA-2026-0199.

Common Misreadings of This Proposal

The SBA size standards proposal has generated significant coverage since August 20, and some of it overstates or mischaracterizes what the rule actually does. Here is what it does not do:

It is not a final rule. No new size standards are in effect. The SBA published a proposed rule and a revised methodology for public comment. If finalized, the new standards would take effect after a final rule is published, which could be months away. Business owners should not make financial decisions based on a proposed change that has not been adopted.

It does not create new funding. The proposal changes who qualifies as a small business under existing SBA programs. It does not increase the total funding available for those programs. More eligible businesses competing for the same pool of SBA-backed loans means preparation and a strong application matter more, not less.

It does not guarantee loan approval. SBA eligibility is one gate. Lenders still evaluate creditworthiness, business viability, collateral, and repayment capacity. Qualifying as a small business under the size standards gives you access to apply; it does not guarantee approval.

It does not change state licensing requirements. Starting a medical billing business still requires the same state-level business registration, tax identification, and compliance steps regardless of federal size standard changes. The SBA proposal affects federal program eligibility only.

In-House Funding vs. SBA-Backed Startup Capital

Not every billing startup needs an SBA loan. The decision depends on how much capital you have available, how quickly you want to scale, and how much risk you are comfortable carrying personally.

A solo medical billing business can launch with relatively low overhead. A training program, practice management software, a clearinghouse account, and basic marketing tools represent the core startup costs. Many of our students at Medical Billing Opportunity fund these costs out of savings or existing income, particularly those starting with the MBU Lite Course at $4,999.

SBA financing makes more sense when the goal is to launch faster, invest in a comprehensive mentorship program, or enter the market with professional infrastructure from day one. The Standard Course at $17,999 includes a company website, CRM with prebuilt automation, Adam’s 6-figure business framework, and a guarantee of your first two clients. Financing that investment through an SBA microloan at favorable rates can preserve personal savings while accelerating the timeline to revenue.

The question one of our students asked recently captures it well: “Do I spend six months saving up, or do I borrow at 7% and start earning in 60 days?” Both paths work. The SBA’s expanded eligibility makes the second path available to more people.
