PPP and 401-K contribution

Client owns a S-Corp and makes elective deferrals contribution to his solo 401-K for retirement.

His monthly salary is $7,000 and he makes $1,500 elective deferrals for the solo 401-K plan.

When the S-Corp makes deposit of the $1,500 elective deferrals to his solo 401-K account, it can be paid from the PPP loan money as the $1,500 is part of the eligible payroll costs.

Does anyone agree or disagree?

His gross wages are $7,000 and the $1,500 is included in the $7,000. $7,000 can be paid from PPP funds.

Yes, I agree the $1,500 elective deferral is part of his $7,000 wages. But it is deposited to his 401-k account, not included in the paycheck to be written to him. That is what is somewhat throwing me off.

All components of the $7,000 gross pay can be paid with PPP funds.
