An accountable plan is a reimbursement arrangement that lets your company pay you back for business costs you covered personally, such as the business share of your phone, internet, home office, mileage and sourcing trips, without the payment counting as taxable wages. When the plan meets the IRS rules, the money stays off your W-2 and the business still deducts the expense.
For Amazon and Shopify sellers who work from home, the plan matters most after an S corp election. As a sole proprietor you claimed home office and vehicle costs directly on Schedule C. Once you are an employee of your own S corp, those personal-side deductions mostly disappear, and reimbursement under an accountable plan becomes the clean way to recover the same costs.
Why Qualifying Reimbursements Are Not Wages
The IRS treats a reimbursement under a valid plan as repayment of a business cost, so it is left out of your gross income. The company withholds no income tax and pays no payroll tax on it.
Compare two ways of moving $500 to yourself. Paid as extra salary, the $500 is taxable wages, with income tax plus both halves of payroll tax. Paid as reimbursement for documented supplier mileage and the business share of your phone bill, it reaches you intact, and the company books it as vehicle and phone expense. The plan does not create a deduction that did not exist. The cost must already be a legitimate business expense; the plan only controls how the repayment is treated.
What Happens Under a Nonaccountable Plan
Any reimbursement setup that fails the IRS tests is nonaccountable, and every dollar paid under it is taxable wages reported on Form W-2. Flat monthly allowances with no receipts are the classic case. A seller who takes a $300 monthly “phone and internet allowance” without records turns $3,600 a year into taxable income, while the same costs tracked and repaid under an accountable plan would have reached them tax-free.
Who Can Be Covered
Any employee can be covered, including you as an S corp owner-employee, since the election makes you both shareholder and employee. A single-member LLC taxed as a sole proprietorship has no employee relationship with its owner, so that owner keeps deducting costs on Schedule C. Partners in a multi-member LLC follow separate partnership reimbursement rules.
The Three IRS Requirements
A plan must satisfy all three tests: a business connection for each expense, adequate accounting within a reasonable time and return of any excess. Fail one, and the payments fall under the nonaccountable rules.
Business Connection
The cost must arise from work you do for the company and would be deductible by it. Driving to your 3PL to inspect an inbound shipment qualifies. A family dinner does not. Mixed-use costs need a split: if your phone is 60% business, only 60% belongs in the plan. Record how you set the percentage, such as a sample month of call logs, and apply the same method every month.
Adequate Accounting Within a Reasonable Time
You substantiate each expense by showing the amount, date, place and business purpose, usually with an expense report plus receipts or a mileage log. A bank or card statement alone is weak proof, because it shows the payee and amount but not what you bought or why.
Under the IRS fixed date method in Treasury Regulation 1.62-2, substantiating an expense within 60 days after you pay it counts as a reasonable time. A monthly report keeps you well inside that window. A shoebox of receipts handed over at year-end does not.
Returning Excess Amounts
Under the same safe harbor, returning any excess within 120 days after the expense is reasonable, and an advance should be paid no more than 30 days before you expect the cost. If the company advances $2,000 for a sourcing trip and you document $1,700, the extra $300 goes back. Keep it, and it becomes taxable wages. The simplest approach is to skip advances altogether and reimburse only after you submit receipts.
Seller Expenses That Commonly Qualify
Most seller reimbursements fall into four groups: the business share of home costs, business driving, sourcing travel and items bought on a personal card. Whether a cost counts in the first place is covered in our list of deductions available to online sellers; this section stays on the reimbursement side.
Home Office, Phone and Internet
The company can reimburse home office costs when the space is used regularly and only for the business. You work out the office’s share of your home and apply it to rent or mortgage interest, utilities, insurance and similar costs. The qualification rules are set out in our post on what ecommerce owners can write off for a home office. In practice, you keep paying the household bills personally, total them each month, apply your percentage and submit one report. A $90 phone bill at 60% business use becomes a $54 reimbursement.
Business Mileage
Mileage covers driving for the business: prep center runs, supplier visits, retail arbitrage sourcing, post office drop-offs and bank trips. Each log entry needs the date, destination, purpose and miles. Commuting does not count. If your home office is your main place of business, a trip from home to a supplier is business travel. If you rent a warehouse and drive there every day, that drive is commuting.
Most sellers reimburse at the IRS standard mileage rate for the date the miles were driven. The IRS raised the 2026 business rate partway through the year, from 72.5 cents per mile for January through June to 76 cents from July 1, according to its standard mileage rates page, so a mileage log that spans both halves of 2026 needs two rates.
Trade Shows and Sourcing Trips
Trips to the Canton Fair, a Las Vegas trade show or a factory visit can be reimbursed when the main purpose is business. Airfare, hotels, local transport and show fees all fit, and the company’s deduction for meals is generally limited to 50%. You can reimburse actual costs with receipts or use IRS per diem rates for meals and incidentals, which removes the need for meal receipts but still requires proof of time, place and purpose. If you own more than 10% of the company, the per diem rules are more restrictive, so most owner-employees reimburse actual hotel costs and keep receipts.
Purchases on a Personal Card
Packaging, a label printer or a software plan bought on your personal card can be repaid through the plan and booked to the right account. The risk is double counting. If a receipt is uploaded to the business books and the same cost is also deducted on a personal return, it has been claimed twice. Record each item once, as a reimbursed business expense, and keep a note linking the receipt to the repayment.
Running the Plan Month to Month
A working plan needs a written policy, a steady monthly report and clean bookkeeping entries. Those pieces are what you hand over if the IRS ever asks.
Adopt a Written Policy First
The law does not require a written plan, but you should have one. Name the expenses you cover, the 60-day reporting deadline, the 120-day return rule and who reviews reports. Adopt it by corporate resolution or written consent, dated before reimbursements begin, and apply it going forward only.
Use a Consistent Expense Report
Each report should list the date, vendor, amount, category, business purpose and supporting receipt or log. For mixed-use bills, show the full bill, the percentage and the reimbursed amount. As the only owner, you still approve your own report as the corporate officer, so sign and date it, and store the report, receipts, approval and proof of payment together.
Worked Example: One Month of Seller Reimbursements
An S corp owner selling on Amazon and Shopify submits an October report on November 5.
| Expense | Calculation | Reimbursed |
|---|---|---|
| Phone | $90 bill at 60% business use | $54 |
| Internet | $80 bill at 50% business use | $40 |
| Home office | Office share of rent and utilities | $210 |
| Mileage | 150 logged miles at 76 cents | $114 |
| Shipping supplies | Bought on personal card | $65 |
| Total | $483 |
The company pays $483 in one transfer. In the books, each line goes to its own expense account: phone, internet, rent or home office, auto and supplies. None of it touches payroll, and none of it is coded as a shareholder distribution. Repeated every month, that is $5,796 a year reaching the owner without income or payroll tax, assuming the same amounts.
Few sellers have months this tidy. Shared vehicles, a garage used for inventory or a spouse who also works in the business all change the split, and those are good reasons to get your reimbursement percentages checked by a CPA before the first report.
Habits That Break the Plan
Flat amounts without records break the plan, even when they look reasonable. So does reimbursing 100% of a bill that is half personal. Wage substitution is the subtler problem: if your salary drops by $500 a month just as reimbursements rise by $500, the IRS can treat those payments as disguised wages. Charging mixed-use bills straight to the business card causes similar trouble, because it blends personal and business money before anyone splits it. This plan is general information to adapt with your advisor, not a template that fits every store.
Frequently Asked Questions
Can an LLC use an accountable plan?
Yes, once the LLC is taxed as an S corp or C corp, and any LLC can use one for non-owner employees. A default-status LLC handles owner costs differently: a sole owner deducts them on Schedule C, and partners follow the partnership rules and their operating agreement.
Does the plan have to be filed with the IRS?
No. Nothing goes to the IRS, and the plan lives in your own company records. A written policy adopted in your company records is still far easier to defend, so keep it with your minutes and expense reports.
Do I need a receipt for every expense?
Generally, documentary evidence is required for lodging at any amount and for other expenses of $75 or more. Below $75, you still record the amount, date, place and purpose. Many sellers require receipts for everything anyway because it keeps the books cleaner.
Can my S corp reimburse my health insurance through the plan?
Not in the usual way. For an owner holding more than 2% of the shares, company-paid health insurance premiums are reported as wages on the W-2, though they are generally exempt from Social Security and Medicare tax. That treatment follows its own rules outside the accountable plan.
Can the company reimburse expenses from before the plan was adopted?
Costs incurred before adoption sit outside the plan. Adopt the policy as early as you can after the S corp election takes effect, then start monthly reports from that date.
Recover What You Already Spend on the Business
Many sellers who elect S corp status keep paying for phones, home offices and sourcing trips personally and never recover that money tax-free, which leaves cash on the table every month.
