The accountable plan: reimburse yourself tax-free
The short answer
An accountable plan lets your business reimburse you for business expenses tax-free: the company deducts the payment, and it never shows up as income to you. For S-corp owners it's the clean way to recover home office costs, mileage, cell phone, and travel. Three rules make it work: a real business connection, substantiation (receipts and logs on a schedule), and returning any excess advances.
Who this works for — and who it doesn't
Good fit
- S-corp and C-corp owner-employees paying business costs personally
- Businesses with employees who spend their own money on work
- Anyone already electing S-corp status — this pairs with it almost automatically
Not a fit
- Sole proprietors — you deduct expenses directly on Schedule C; no plan needed
- Owners who want a flat monthly "allowance" with no receipts — that's wages, not a reimbursement
- Expenses with no genuine business purpose
How it works
- Adopt a short written policy. One or two pages stating what's reimbursable, the substantiation deadline, and the excess-return rule.
- Track and submit. Expense reports with receipts, a mileage log, and a documented business-use percentage for mixed items like your phone and home office — submitted within a reasonable period (60 days is the common benchmark).
- The company pays you back from the business account. It deducts the expense; you receive it tax-free — no W-2, no 1099, no payroll tax.
- Return anything extra. If the company advanced more than you substantiated, the excess goes back (120 days is the common benchmark) — or it becomes taxable wages.
A worked example
Marcus owns an S-corp agency and works partly from a dedicated home office that's 15% of his home. His accountable plan reimburses him quarterly:
Marcus's annual reimbursements
At a combined federal and California marginal rate around 40%, that documentation is worth roughly $3,300 a year — every year — for a few hours of record-keeping. Illustrative only; your percentages and rates will differ.
Common mistakes that draw IRS attention
- Flat monthly stipends with no receipts behind them
- Reimbursing 100% of a phone or internet bill that's obviously partly personal
- Home office reimbursements without a measured square-footage percentage
- No written plan and no expense reports when the auditor asks
Frequently asked questions
Do I need a written accountable plan?
A written plan is not strictly required by the regulations, but in practice it is your first line of defense in an audit. Adopt a short written policy, keep it with your corporate records, and follow it.
Can I reimburse my home office through an accountable plan?
Yes — for S-corp owner-employees this is the standard way to get a home office benefit. The corporation reimburses your documented share of home expenses, deducts it, and the reimbursement is not income to you.
What substantiation does the IRS expect?
Business purpose, amount, and date for each expense — receipts, mileage logs, or expense reports submitted within a reasonable period (commonly 60 days), with any excess advances returned (commonly within 120 days).
What happens if we skip the paperwork?
Reimbursements under a nonaccountable arrangement are treated as wages — taxable to you and subject to payroll taxes. The paperwork is the entire difference between tax-free and taxable.
Want this set up with the right paperwork?
We draft the plan, set the reimbursement schedule, and build the substantiation habit into your monthly accounting — so the tax-free treatment survives an audit.
