Reimbursement policy and tax treatment should match
An accountable plan is built around business connection, substantiation, and returning excess advances. It is not simply a label placed on any payment to an employee or owner.
The company should adopt a written process that reflects the current IRS rules and how employees actually submit expenses.
Require enough evidence to support the business purpose
Collect date, amount, vendor, location where relevant, business purpose, receipt or invoice, and the employee or owner who paid. Mileage, travel, meals, home-office arrangements, and other categories can require additional detail.
Use one submission path so reimbursements do not arrive through scattered messages.
Handle advances separately
If the company gives money before the expense occurs, track the advance until receipts are submitted and any excess is returned. Do not treat an unresolved advance as a completed reimbursement.
Aging advances should appear on a monthly exception list.
Keep reimbursement out of wages when the rules support it
Qualifying accountable-plan reimbursements can receive different payroll treatment from taxable compensation, while nonqualifying payments may need to be included in wages. Payroll and bookkeeping should therefore use the same approved reimbursement classification.
Tax-specific decisions should be reviewed with the company's tax adviser rather than made from the payment method alone.

The arrangement generally needs a business connection, adequate substantiation, and a process for returning excess advances, subject to current IRS rules.
Can an S corporation shareholder use an accountable plan?
A shareholder-employee can potentially be reimbursed under an accountable plan, but the company should follow the same substantiation and tax rules that apply to the arrangement.
