On June 24, 2019, the U.S. Small Business Administration published a rule proposing to amend the time period for calculating average annual receipts for SBA’s receipts-based size standards from three to five years. This rule would implement the congressional intent behind the Small Business Runway Extension Act of 2018, which the SBA previously instructed did not permit small businesses to immediately begin certifying against a five-year time period. In the proposed rule, the SBA again warns that the three-year calculation period continues to apply to any offer submitted prior to the effective date of a final rule. Comments on the proposed rule are due by August 23, 2019.
