SBA size protests are only timely if received within five business days. The SBA size protest timeliness rule can confuse potential protesters, because it is different than the 10-day rule applicable to most post-award GAO bid protests.
In a recent SBA Office of Hearings and Appeals decision, a would-be protester apparently got tripped up by the different filing periods, incorrectly interpreting a solicitation provision regarding GAO bid protests as establishing an extended SBA size protest filing deadline. SBA OHA held that the protester’s misunderstanding did not entitle it to file a late SBA size protest.
