UPDATE: Effective October 1, 2015, the threshold increases to $750,000. See details here.
Effective October 1, 2010, the threshold for requiring certified cost or pricing data (FAR 15.403-4(a)) is increased for inflation from $650 thousand to $700 thousand. A slew of other inflation-related thresholds are increased as well. For a complete matrix of all FAR thresholds by FAR cite, click here.
In publishing these adjustments, the FAR councils were careful to point out that "... the intent is not to reduce Government oversight but to maintain the status quo, by adjusting thresholds to keep pace with inflation. If thresholds are not adjusted for inflation, the number of contracts subject to the acquisition-related threshold will continue to grow, because more and more contracts will be above the stated thresholds."
