Now that Paycheck Protection Program (PPP) funds are landing in business accounts, it’s time to dig into how PPP loan forgiveness is taxed.

On March 18, 2020, Congress enacted the Families First Coronavirus Response Act (the “Act”) providing for paid sick leave and expanded family and medical leave for coronavirus-related reasons and creating refundable credits for eligible employers. Eligible employers are businesses and tax-exempt organizations with fewer than 500 employees required to provide emergency paid sick leave and emergency paid family and medical leave under the Act. The IRS issued guidance on receiving the refundable credits.
The coronavirus (COVID-19) epidemic was recently declared a disaster under the Stafford Disaster Relief and Emergency Act. This triggers special tax treatment for qualified disaster relief payments (“QDR payments”). To the extent not covered by insurance or other means, QDR payments to an individual are not taxable for federal income and employment tax purposes.
JOBS Act Directs SEC to Lift Ban on General Solicitation and General Advertising in Rule 506 Offerings

As discussed in a previous Tonkon Tip, the Securities and Exchange Commission issued an order raising the financial thresholds of Rule 205-3 under the Investment Advisers Act of 1940, which provides that only “qualified clients” may be charged a performance-based fee.
