Let’s turn to New Jersey.
According to the NJ-1040 instructions for the NJ-1040 for 2021, generally, only medical expenses that are allowed for federal tax purposes are allowed as medical expenses for New Jersey, Daquila said.
Therefore, medical marijuana is not allowed as a medical expense for New Jersey currently because it is disallowed for federal taxation purposes, she said.
“This was confirmed by an email with the Taxation Regulatory Services for New Jersey,” she said. “Even if it was allowed as a medical expense for New Jersey, you can only deduct medical expenses in New Jersey that are more than two percent of your gross income.”
