SBA Size Standards: How to Determine if Your Business Qualifies as Small

SBA size standards are numerical definitions of what constitutes a "small business" for each industry. They vary by industry because a $10 million company might be tiny in construction but massive in consulting.

Two types of size standards:

Revenue-based: Most industries use average annual receipts over the past 3-5 years. Example: Management consulting (NAICS 541611) has a $24.5 million standard.

Employee-based: Manufacturing and some other industries use number of employees. Example: General construction (NAICS 236220) has a 1,500 employee standard.

Why size matters:

• Small business set-asides — Can't compete if you're not small
• SBA certifications — 8(a), HUBZone, etc. require small status
• Subcontracting goals — Primes need small business subs to meet goals
• Contract vehicles — Many GWACs and IDIQs are small business only

Where to find size standards:

Official table: sba.gov/size-standards

Each NAICS code has its own size standard. You must check the standard for your specific code — don't assume they're all the same.

Professional Services:

• Management Consulting (541611): $24.5 million
• Computer Systems Design (541512): $34 million
• Engineering Services (541330): $25.5 million
• Accounting Services (541211): $27.5 million
• Marketing Research (541910): $22 million

IT and Technology:

• Custom Computer Programming (541511): $34 million
• Data Processing Services (518210): $40 million
• Software Publishers (511210): $47 million
• IT Training (611420): $15 million

Construction:

• Commercial Building (236220): $45 million
• Electrical Contractors (238210): $19 million
• HVAC Contractors (238220): $19 million
• Highway Construction (237310): $45 million

Manufacturing (by employees):

• Most manufacturing: 500-1,500 employees
• Check specific NAICS for exact standard

Important: These standards change periodically. Always verify current standards at sba.gov before bidding.

Revenue-based calculation:

1. Find your primary NAICS code
2. Look up the size standard for that NAICS
3. Calculate your average annual receipts for the past 5 fiscal years
4. Compare: If average receipts < size standard, you're small

Example calculation:

NAICS 541611 (Management Consulting) — $24.5 million standard

• Year 1: $18 million
• Year 2: $20 million
• Year 3: $22 million
• Year 4: $25 million
• Year 5: $28 million
• Average: $22.6 million — Still qualifies as small

Employee-based calculation:

1. Count all employees (full-time, part-time, temporary)
2. Any person on payroll counts as one employee regardless of hours
3. Average over the past 24 months (changed from 12 months per Public Law 116-283)
4. Compare to standard for your NAICS

What counts as "receipts":

• All revenue from sales of products/services
• Interest, dividends, rents, royalties
• Commissions, fees, other income
• Excludes: Net capital gains, taxes collected for government

Affiliation is the biggest trap in size determination. If SBA considers you affiliated with another business, their revenue/employees count toward YOUR size.

Common affiliation triggers:

• Ownership — Own 50%+ of another business, or they own 50%+ of you
• Common management — Same people control both businesses
• Family relationships — Businesses owned by family members may be affiliated
• Economic dependence — 70%+ of revenue from one source may indicate affiliation
• Newly organized concern — Created to avoid size standards
• Joint ventures — JV partners may be affiliated (see exceptions below)

How affiliation affects you:

If you're affiliated with a $50 million company, SBA adds their $50 million to your revenue for size calculation — even if you're a tiny firm.

Affiliation exceptions:

• Mentor-protégé — Approved mentor-protégé relationships don't create affiliation
• SBA-licensed investment companies — SBICs have special rules
• Franchise agreements — Franchisees may not be affiliated with franchisor

When in doubt: Consult with an attorney experienced in SBA size matters. Affiliation mistakes can result in False Claims Act liability.

When does your size get evaluated? It depends on the type of procurement.

Negotiated procurements (most services):

Size determined at time of initial offer including price. If you're small when you submit, you're small for that contract — even if you grow during performance.

Sealed bidding:

Size determined at time of bid opening.

Multiple Award Contracts (IDIQs, GWACs):

Size determined at time of initial offer for the base contract. For task orders, you generally don't need to re-certify size unless the vehicle requires it.

Long-term contracts:

Some contracts require recertification:

• At option exercise
• When contract is novated (transferred)
• When acquiring another company

SBA certifications:

For 8(a), HUBZone, etc., you must remain small throughout certification. SBA reviews annually.

Strategic planning:

If you're approaching the size threshold, pursue contracts NOW while you still qualify. Once you exceed the standard, you lose access to set-asides in that NAICS.

Size protests:

Competitors can challenge your size status by filing a protest with SBA's Office of Hearings and Appeals (OHA).

Who can protest:

• Other offerors on the same procurement
• The contracting officer
• SBA

Protest timing:

• Must be filed within 5 business days of learning apparent awardee
• For certain contracts, may be filed before award

What happens during a protest:

1. SBA issues a size determination request to you
2. You have 3 business days to respond with documentation
3. SBA Area Office makes size determination
4. Either party can appeal to OHA

Consequences of being found "other than small":

• You're ineligible for that contract award
• May affect other pending set-aside contracts
• Must update SAM.gov size representations

Best defense: Maintain accurate records. Document your size calculation methodology. Keep affiliation analysis current. Don't wait for a protest to gather information.

Approaching the threshold:

If you're growing toward the size limit, take action NOW:

• Get on contract vehicles — Win IDIQs while still small; you can compete for task orders even after exceeding the threshold
• Pursue large set-asides aggressively — Win what you can while you qualify
• Consider NAICS code strategy — Different NAICS may have higher thresholds

Exceeding the threshold:

When you grow beyond small business size:

• Update SAM.gov — Misrepresenting size is fraud
• Transition to full-and-open — Compete on capabilities, not status
• Become a mentor — Use the Mentor-Protégé Program to access small business work
• Subcontract to small businesses — Help primes meet their small business goals

Multiple NAICS codes:

You may be small under some NAICS codes but not others. Track your size status by NAICS. Pursue set-asides only in NAICS where you qualify.

Acquisitions and growth:

If you acquire another company or merge, recalculate your size immediately. The combined entity's revenue/employees count from day one of the transaction.
