You approved a $75-a-month internet stipend so your remote employee can stay connected. It feels like a simple reimbursement: money out for a business cost, everyone happy. Then payroll runs, your bookkeeper asks whether it belongs on the W-2, and you realize the answer could add 7.65% in employer payroll taxes — plus income tax for your employee — for the entire year.
The difference is not the expense itself. Internet, phone, a monitor, a desk chair — all can be legitimate business costs. The difference is how you pay for them. The IRS recognizes only two paths, and only one keeps reimbursements tax-free and off the W-2.
The Two Paths the IRS Actually Recognizes
Every arrangement to cover employee costs falls into one of two buckets defined in IRS Publication 15 and Treasury Regulation §1.62-2. The label matters because it determines tax and payroll treatment.
Path 1: Nonaccountable plan — the taxable stipend
This is the flat allowance you run through payroll with no strings attached: "150 remote work stipend," "$50 phone." You do not ask for a bill, you do not ask what portion was business use, and you do not ask for any unspent amount back.
Under a nonaccountable plan — or when you have no written plan at all — the IRS treats the entire payment as supplemental wages:
- It is included in Box 1 of Form W-2
- It is subject to federal income tax withholding, Social Security, Medicare, and federal unemployment tax
- You, the employer, pay the matching payroll taxes
- Your employee takes home less than you paid
That 75 of internet for your employee. After withholding, it may buy 60, depending on their bracket. You still deduct it, but as wages, not as a reimbursement of a business expense.
It is simple, and for some teams simplicity is worth the tax cost. But if you reimburse the same employee 69 in employer payroll tax and reduced the value to your employee by 20% to 30%.
Path 2: Accountable plan — the tax-free reimbursement
An accountable plan is a written arrangement that meets three strict IRS requirements. When you meet all three, reimbursements are:
- Excluded from the employee's gross income
- Exempt from withholding and payroll taxes
- Not reported as wages on the W-2
- Still deductible as a business expense for you
In other words, the business deducts the cost, the employee keeps every dollar, and payroll stays clean. The trade-off is documentation.
The Three Requirements That Make a Plan Accountable
All three must be met. Miss one, and the whole arrangement is treated as nonaccountable — the entire amount becomes wages, not just the undocumented portion.
1. Business connection
The expense must be deductible if the business had paid it directly and must be incurred by the employee in connection with services performed for you.
For remote work, that typically includes:
- The business-use portion of home internet and cell service
- Equipment necessary to do the job: monitor, keyboard, headset, webcam
- Ergonomic furniture required for a home workstation
- Software and subscriptions you require for work
It does not include decor, personal streaming upgrades unrelated to work, or a blanket "wellness" allowance. You can offer wellness dollars, but they cannot ride inside an accountable plan as tax-free if they lack a business connection.
How you handle mixed-use costs matters. If an employee's household internet is $90 and they work from home full-time, many employers reimburse 50% to 75% as a reasonable business-use allocation, provided the policy explains the method. The key is that the allocation is business-related and applied consistently.
2. Substantiation within a reasonable time
The employee must adequately account to you for each expense: amount, time, place (or use), and business purpose. For remote work costs, that usually means:
- A copy of the internet or phone bill showing the charge
- A receipt for equipment with date and vendor
- A short notation of business purpose ("home internet — required for video calls and VPN," "second monitor — software development")
- For ongoing monthly costs, a monthly submission on a simple expense report
The IRS safe harbor for "reasonable time" is widely used by payroll providers and CPAs:
- Substantiation within 60 days after the expense is paid or incurred
- Return of any excess advance within 120 days
- Advances, if you give them, within 30 days before the expected expense
You can also use the periodic-statement method: give at least quarterly statements showing amounts paid versus amounts substantiated and require the employee to account or return the balance within 120 days of the statement. Whichever method you choose, put it in writing and follow it the same way for everyone.
3. Return of excess amounts
If you advance or reimburse more than what was actually spent or substantiated, the employee must return the excess within a reasonable time. A classic mistake is paying a 75 and letting the employee keep the 25 must come back. If it does not, the entire arrangement can lose accountable status.
This is why many small businesses avoid advances for recurring remote costs and instead reimburse after the employee submits the bill. No advance means nothing to return and no excess to track.
What Good Substantiation Looks Like for Remote Work
You do not need a complex expense system to meet the standard, but you do need a consistent process and records you could show in an audit.
Monthly internet and phone: Employee submits the provider invoice or a screenshot of the billing statement plus the employee's calculation of the business-use percentage defined in your plan. Keep the statement for seven years along with the reimbursement record.
Equipment: Employee submits a receipt before or at the time of reimbursement and notes that the item is business-owned or assigned to a business purpose if it stays with the employee. For items over $2,500, consider whether capitalization is more appropriate than immediate expensing under your de minimis safe harbor election; your CPA can confirm the threshold you have in place.
Tiered allowances done correctly: You can offer different levels without violating the rules, as long as each level is tied to substantiated costs:
- Base tier — internet and phone business-use portion
- Mid tier — plus work-required peripherals and software
- Role-specific tier — travel tools, specialized equipment, or home-office setup for roles that require it
Tiering by role is allowed when it reflects business need. Tiering by compensation level alone, with no link to substantiated expenses, looks like disguised compensation.
The Payroll and Bookkeeping Mechanics
Getting the accounting right is as important as getting the plan language right, because the books are what an auditor, lender, or software audit will actually see.
Under a nonaccountable plan or flat stipend:
- Code it as wages: credit Cash, debit Payroll Expense — Remote Stipend (or Wages)
- Run it through payroll with withholding; it appears in W-2 Box 1, and Boxes 3 and 5 for Social Security and Medicare wages
- Employer payroll tax is debited to Payroll Tax Expense
Under an accountable plan:
- Code it as a reimbursement of employee business expense, not wages: credit Cash, debit Employee Reimbursable Expenses or the natural expense account (Internet, Telephone, Office Equipment)
- Do not run it through payroll as wages
- Do not withhold, do not report on W-2, do not pay employer payroll tax on the amount
- Retain the expense report, receipt, and proof of payment together — your expense report is the substantiation file
Create separate general ledger accounts for accountable-plan reimbursements versus taxable allowances. When you reconcile your bank feed, a tag like "Remote: Accountable Reimbursement — Not W-2" prevents a bookkeeper from later reclassifying it as miscellaneous compensation during year-end cleanup.
If you use a payroll provider, set up two pay types now: "Remote Stipend — Taxable" and "Accountable Reimbursement — Non-Taxable." The naming alone prevents the most common error, which is running a properly substantiated reimbursement through payroll as taxable wages because no one told the system it was different.
And do not let employees deduct the costs themselves. Since the 2018 tax changes, W-2 employees cannot deduct unreimbursed employee business expenses on their personal return for federal purposes. The only way for them to be made whole tax-free is through your accountable plan.
The State-Law Wrinkle You Cannot Ignore
Federal tax rules tell you whether a reimbursement is taxable. State labor law tells you whether you must make it at all.
A growing minority of states require employers to reimburse necessary business expenses incurred by employees. California Labor Code § 2802 is the most cited: it obligates employers to indemnify employees for necessary expenditures incurred within the scope of employment, and a flat allowance without substantiation does not automatically satisfy it. Illinois, Iowa, Montana, New Hampshire, North Dakota, South Dakota, and several others have similar statutes, and a handful of cities add their own rules.
Even where no specific reimbursement statute applies, failing to cover required remote-work costs can create wage-and-hour risk if the unreimbursed expense effectively pushes an hourly employee below minimum wage.
The practical takeaway: check the states where your remote employees actually sit, not just where your entity is registered. If even one employee is in a mandatory-reimbursement state, a documented accountable plan does double duty — it keeps the payment tax-free for IRS purposes and satisfies the state requirement to reimburse actual, necessary costs.
Five Mistakes That Flip a Good Plan to Taxable
1. No written plan document
An oral understanding does not count. The IRS expects a written plan stating the business connection, the substantiation requirement, the excess-return requirement, and the timing rules you have adopted. Keep it with your employee handbook and have employees acknowledge it.
2. Accepting a single receipt for a year of monthly costs
One January internet bill does not substantiate twelve $75 payments. Require monthly documentation. For recurring bills, a one-page monthly expense report that lists date, amount, vendor, and business purpose is enough.
3. Letting the stipend exceed the bill without a return
Paying 70 and winking at the difference is not an accountable plan. Reimburse the substantiated amount, or collect the excess back within your stated window.
4. Mixing personal perks into the tax-free bucket
A Peloton membership, a lunch stipend, or a general "work-from-home wellness" payment may be a great benefit, but it is wages unless there is a specific business connection. Pay it as a taxable perk and avoid contaminating your accountable reimbursements.
5. Forgetting advances and cross-year timing
If you advance $1,000 for a home-office setup in December and the employee substantiates in February, you are outside the 60-day safe harbor for substantiation unless your plan uses the periodic-statement method correctly. For most small teams, the safer habit is simply to reimburse after purchase.
How to Set Up an Accountable Plan in a Week
You can move from taxable stipends to a compliant accountable plan without hiring a large firm or buying new software.
Day 1–2: Draft the plan. Write a one- to two-page document covering: purpose, who is eligible, which expense categories are covered, business-connection language, how employees substantiate (what to submit and where), the 60-day/120-day timing rules or periodic-statement alternative, and the excess-return rule. Have your CPA or payroll provider review it once.
Day 3: Build the submission habit. Create a simple template: date, vendor, amount, business purpose, receipt attached. Use email, a shared drive folder per employee, or your existing expense tool. The tool matters less than the consistency. Store submissions with the reimbursement transaction.
Day 4: Train managers and pick accountable categories. Decide what you will and will not cover tax-free. A common starting list: business-use portion of internet and phone, required peripherals up to a cap per year, and software you mandate. Communicate the tiers and the percentage method for internet/phone.
Day 5: Align payroll and accounting. Create the two pay types, set up the GL accounts, and tell your bookkeeper which one to use for each situation. Run a test reimbursement for one employee and confirm it does not appear on a sample W-2.
Ongoing: Quarterly sweep. Each quarter, generate a statement per employee showing amounts reimbursed and amounts substantiated, request any missing substantiation, and document any returns of excess. Keep everything for at least seven years — the IRS can question payroll reporting well after year-end, and good state-law records follow the same horizon.
A Quick Decision Guide
- You want zero admin and everyone gets the same dollar amount regardless of actual cost? Pay a flat, taxable stipend through payroll. Budget for employer payroll tax and tell employees the take-home math.
- You want employees to receive the full dollar amount, you want no payroll tax on the reimbursement, and you are willing to collect a bill each month? Adopt a written accountable plan and reimburse only what is substantiated.
Many employers land in the middle: they run taxable stipends for lifestyle perks and an accountable plan for the core business costs. The labels — and the W-2 treatment — must match the substance every month, not just when the plan was written.
Simplify Your Financial Management
