There are limits for individuals and there are limits for companies. There are limits for individuals of $5,000--so anything up to $5,000 for an individual and anything up to $25,000 for a company. Depending on the frequency and the severity, if you like, there's some judgment from an enforcement point of view as to what particular penalty is applied in each case.
