An accountable plan is an employee reimbursement allowance arrangement or a method for reimbursing employees for business expenses (home office/auto/mileage) that complies with IRS regulations.
All you do is write yourself a reimbursement each month and make sure the money moves from the corp account, to your personal every month.
Make sure you document what the expenses are each month, the amounts should always be different.
Then the IRS can't touch you.
If you only do quarterly, then it won't work. Must be each month or every 60 days.
You cannot set this up retroactively, has to be done in the tax year.
