This is our understanding of it:
Because of the extensions provided by the IRS, the deadline to make loan repayments due on or after April 1 (without running afoul of the deemed distribution rules), is extended to July 15. This applies to all loans, not just loans to Qualified Individuals which can enjoy a longer suspension period under the CARES Act. With maximum use of regulatory cure period provisions, a participant can make up any missed payments by December 31. For example, if a “non-qualified individual” stops making payments any time during the period of 4/1/2020 through 7/15/2020, it’s treated as if the payments stopped during Q3 2020, thus making the end of the cure period 12/31/2020.
