How tribal enterprises win federal contracts: 8(a), Buy Indian Act and the Indian Incentive Program
How can a tribally owned business win federal contracts?
Through three routes. A tribally owned small business can join SBA's 8(a) program and receive sole-source awards above the usual 8(a) ceilings. A firm at least 51 percent owned by Indians or federally recognized tribes can compete for Buy Indian Act set-asides at Indian Affairs and the Indian Health Service. Under the Indian Incentive Program, a prime contractor can earn 5 percent of what it pays an Indian-owned subcontractor. That makes a tribal enterprise a valuable teaming partner.

8(a): the largest door
SBA's 8(a) Business Development program admits small businesses owned by Indian tribes, Alaska Native corporations and community development corporations. Certification lasts up to nine years. The first four are a developmental stage and the last five are transitional.
For most participants a sole-source 8(a) award tops out at $8.5 million in manufacturing and $5.5 million elsewhere. Tribally owned firms have different access. They can receive sole-source contracts above those ceilings, with a formal justification required at the Defense Department above $100 million and agency approval elsewhere above $30 million.
A tribe can also hold more than one 8(a) company, where most owners are limited to one. That lets a nation run separate firms in separate industries.
Buy Indian Act set-asides
The Buy Indian Act lets Indian Affairs at the Department of the Interior and the Indian Health Service reserve purchases for Indian Economic Enterprises. Interior's rules in DIAR Part 1480 cover supplies, services, architect-engineer work and construction. HHS applies the Act to IHS through HHSAR subpart 326.6.
An Indian Economic Enterprise is a for-profit business that Indians or federally recognized tribes own at least 51 percent of. Indian owners must also control its management and daily operations. There is no separate certification. The firm represents its status on each set-aside solicitation and has to keep meeting the definition for the life of the contract.
The Indian Incentive Program
FAR subpart 26.1 pays a prime contractor an incentive of 5 percent of the amount it pays to an Indian organization or an Indian-owned economic enterprise as a subcontractor. Indian-owned means at least 51 percent Indian ownership. The Bureau of Indian Affairs decides eligibility if it is challenged. Defense contracts carry their own version of the clause in DFARS 252.226-7001.
Money paid out depends on the contract terms and available funds. Primes have to request it before performance ends. For a tribal enterprise the practical effect is leverage in teaming talks. Every dollar subcontracted to you can earn the prime a bonus on top.
