The Right Way to Get Travel Reimbursements from Your C or S Corporation
If you operate your business as a C corporation or an S corporation, handling travel and other out-of-pocket business expenses the right way isn’t just a good idea—it’s a must. One of the most common mistakes we see at Molen & Associates is business owners treating their corporation’s expenses like their own, and vice versa.
In a sole proprietorship, those lines can be a little blurry, but once you’ve incorporated? The IRS expects you to treat the business as its own separate person—with its own bank account, rules, and documentation.
Let’s walk through the right way to get reimbursed for business travel (and other expenses) to protect your deductions, stay IRS-compliant, and keep more money in your pocket.
💼 Understanding the Relationship Between You and Your Corporation
As a shareholder in a C or S corporation, you’re not just the owner—you’re also an employee.
That distinction matters a lot for tax purposes.
✅ The corporation is a separate legal entity.
✅ It only gets to deduct expenses it pays.
✅ If you pay for something business-related, the corporation must reimburse you to claim the deduction.
If it doesn’t? The expense is not deductible, and you’ve just spent your own money for the business—without any tax benefit.
❌ Can You Deduct Business Expenses Personally?
Here’s where many business owners get tripped up.
No, you can’t.
Thanks to the Tax Cuts and Jobs Act (TCJA), from 2018 through at least 2025, unreimbursed business expenses are not deductible on your personal return.
That includes:
-
Flights to conferences
-
Hotel stays for business travel
-
Meals with clients
-
Business mileage in your personal vehicle
Unless your corporation reimburses you properly, you’re out of luck.
🚫 No deduction.
🚫 No tax-free reimbursement.
🚫 No benefit—just a costly mistake.
🔮 What About 2026?
No one knows yet whether the deduction will come back. So the best move now? Get a reimbursement plan in place and use it.
✅ The Right Way: Use an Accountable Plan
The IRS gives corporations a way to reimburse employees (even if that’s you) tax-free under a structure called an accountable plan.
It’s a win-win when done right:
-
💸 You get reimbursed tax-free
-
🧾 The corporation gets a full deduction
-
🛡️ Proper documentation protects both sides during an audit
Let’s walk through how it works.
🧾 How to Structure an Accountable Plan
Setting up an accountable plan isn’t complicated—but you do need to follow a process and keep good records.
1. Keep Detailed Records
You’ll need to track and document every expense you plan to get reimbursed for.
Examples of qualifying expenses:
-
Airfare, lodging, meals, transportation for business travel
-
Business mileage (use apps like MileIQ or QuickBooks)
-
Internet, cell phone, and home office use (with supporting calculations)
-
Professional development or continuing education
💡 Each expense needs:
-
Date
-
Amount
-
Business purpose
-
Receipt or log
2. Submit an Expense Report
Before your corporation can reimburse you, you need to submit a formal report. This doesn’t need to be complicated—it just needs to show:
-
What was spent
-
When it was spent
-
Why it was for business
-
A receipt or mileage log as backup
Using a template helps ensure consistency and IRS-readiness.
3. Get Reimbursed Promptly
The IRS expects reimbursements to be made within a “reasonable time.” That usually means within 60 days of incurring the expense.
Late reimbursements can trigger issues like:
-
Being treated as wages (taxable!)
-
Denied deductions for the business
-
IRS scrutiny during audits
4. Return Any Overpayments
If the company gives you an advance for travel or expenses and you don’t spend it all? You have to return the unused portion.
Otherwise, the IRS may consider the extra funds as taxable income.
⚠️ Why Proper Reimbursements Matter
It might seem like a small detail, but improper reimbursements can cost you thousands in missed deductions and unnecessary taxes.
Without a proper accountable plan:
-
🚫 Your corporation loses the deduction
-
🚫 You may owe payroll or income taxes
-
🚫 You’re at a higher risk during IRS audits
At Molen & Associates, we’ve seen it all—and we’ve helped many clients clean up messy records before the IRS comes knocking.
🧰 Tools to Help You Stay Compliant
Want to make the process easier? Here are some tools and templates we recommend:
📋 General Expense Reimbursement Form
Use this for lodging, meals, airfare, and more. Include all necessary receipts.
🏡 Home Office Reimbursement Worksheet
Calculate what portion of your home qualifies, and get reimbursed monthly or quarterly.
🚗 Vehicle Mileage Log
If your corporation reimburses you using the IRS mileage rate, this log is a must.
We offer these templates to our clients to help streamline their systems—and make sure nothing slips through the cracks.
🏁 Final Takeaways: Don’t Leave Money on the Table
If you’re paying for business expenses out of your own pocket, don’t assume the corporation can just “write them off.” It can’t—not unless you submit them for reimbursement under an accountable plan.
Here’s the right process:
✅ Track your expenses
✅ Submit them to your corporation
✅ Get reimbursed
✅ Keep your records
This way, you get your money back tax-free, and your corporation gets the deduction. That’s the smart, IRS-approved path to savings.
