Identity of interest exists when individuals or entities are so intertwined that one can exert control over the other or act in concert. This can include immediate family members, former officers/directors who retain influence, or entities with shared financial dependence.","example":"Two separate businesses, each owned 50% by siblings, are found to be affiliated due to shared economic interests and resource use, making their combined revenues exceed the size standard for a new 7(a) loan application.","what_lenders_check":"Lenders must thoroughly investigate all related entities and individuals to correctly apply affiliation rules. Failure to identify and aggregate affiliated businesses can lead to an incorrect size determination and jeopardize the SBA guaranty.","required_facts":["Common investments","Shared financial ties","Resource use","Familial relationships","Control influence"],"source_families":["13 CFR Part 121 - Small Business Size Regulations","SOP 50 10 - Lender and Development Company Loan Programs","Affiliation and Lending Criteria for SBA Business Loan Programs - Final Rule"],"official_sources":[{"title":"13 CFR Part 121 - Small Business Size Regulations","url":"https://www.ecfr.gov/current/title-13/chapter-I/part-121"},{"title":"SOP 50 10 - Lender and Development Company Loan Programs","url":"https://www.sba.gov/sites/default/files/2025-05/SOP%2050%2010%208%20Technical%20Updates%20effective%206.1.2025.docx"},{"title":"Affiliation and Lending Criteria for SBA Business Loan Programs - Final Rule","url":"https://www.federalregister.gov/documents/2023/04/10/2023-07173/affiliation-and-lending-criteria-for-the-sba-business-loan-programs"}],"related_questions":[{"question":"When does a contractual relationship between two businesses trigger affiliation for size standard calculations?","url":"https://dealroom.so/for-lenders/questions/when-does-a-contractual-relationship-between-two-businesses-trigger-affiliation-for-size-s"},{"question":"How does ownership of options or warrants affect affiliation determination for SBA size standards?","url":"https://dealroom.so/for-lenders/questions/how-does-ownership-of-options-or-warrants-affect-affiliation-determination-for-sba-size-st"},{"question":"What are the size standard requirements for a business applying for a 7(a) loan if it operates internationally?","url":"https://dealroom.so/for-lenders/questions/what-are-the-size-standard-requirements-for-a-business-applying-for-a-7-a-loan-if-it-opera"},{"question":"What specific scenarios involving shared directors, officers, or key employees constitute 'common management' triggering affiliation for SBA size determination?","url":"https://dealroom.so/for-lenders/questions/what-specific-scenarios-involving-shared-directors-officers-or-key-employees-constitute-co"},{"question":"Under what conditions does a shared economic interest trigger affiliation for SBA size standard purposes?","url":"https://dealroom.so/for-lenders/questions/under-what-conditions-does-a-shared-economic-interest-trigger-affiliation-for-sba-size-sta"},{"question":"How does the 'totality of the circumstances' rule apply when determining affiliation for SBA size standards?","url":"https://dealroom.so/for-lenders/questions/how-does-the-totality-of-the-circumstances-rule-apply-when-determining-affiliation-for-sba"}],"related_terms":[{"term":"Identity of interest affiliation","url":"https://dealroom.so/glossary/identity-of-interest-affiliation"},{"term":"SBA size determination","url":"https://dealroom.so/glossary/sba-size-determination"},{"term":"size determination","url":"https://dealroom.so/glossary/size-determination"},{"term":"Identity of Interest","url":"https://dealroom.so/glossary/identity-of-interest"},{"term":"Identity of Interest Transaction","url":"https://dealroom.so/glossary/identity-of-interest-transaction"},{"term":"SBA size standard","url":"https://dealroom.so/glossary/sba-size-standard"}],"related_tools":[{"name":"SBA 7(a) payment & fee calculator","url":"https://dealroom.so/sba-7a/calculator"},{"name":"Find an active SBA 7(a) lender","url":"https://dealroom.so/lenders"}],"data_freshness":{"last_reviewed":"2026-06-13","sba_rule_sources_checked_through":"2026-06-13"},"citation":{"label":"DealRoom.so SBA 7(a) Q&A","url":"https://dealroom.so/for-lenders/questions/when-does-identity-of-interest-trigger-affiliation-for-size-determination-under-sba-rules","source_type":"DealRoom Q&A"},"caveats":["Grounded in the current SBA rulebook; verify against official sources before relying on it for a live deal.","Not legal, tax, or financial advice and not an approval decision."]}
