How to Reimburse Expenses Through Your PC and Think Like an Owner

In every conversation I have with physicians who own professional corporations, the same realization eventually surfaces. Most doctors still think about money the way employees do, even though they technically run a business. They receive income. They pay bills. They send everything to the accountant and hope it works out. But they never fully step into the mindset that says, “Your PC is a business. Treat it like one.”

One of the clearest examples of this mindset gap is how physicians handle expenses. Employees pay out of pocket and hope they are reimbursed. Owners use structured systems to turn routine costs into tax free reimbursements that reduce corporate income and increase personal cash flow. Employees see expenses as something to endure. Owners see expenses as strategic tools that shape their financial outcomes.

If you have never used an accountable plan inside your PC, you are leaving real dollars on the table. Not because you are careless, but because no one ever taught you to think differently.

Today I want to walk you through what an accountable plan is, why it matters, and how adopting one changes the way you work with your corporation. But more than anything, I want to help you rewire how you see yourself. Once you understand that your PC is a micro business, not just a shell, everything about your financial life begins to feel different.

The Owner Mindset Behind Reimbursements

Before we talk strategy, we have to talk identity. Employees accept the rules they are given. Owners write their own. When you operate your PC like a real business, you do not casually pay for business expenses out of your personal account and hope your accountant cleans it up later. You build a structure that allows your corporation to reimburse you cleanly and consistently.

This shift does more than save taxes. It changes how you see your relationship with money.

As a physician owner, you can:

• Set reimbursement rules inside your PC

• Classify expenses correctly from the start

• Move money out of taxable wages and into tax free reimbursements

• Lower your corporate taxable income

• Improve documentation and audit protection

• Redirect savings into retirement or other goals

Employees respond to the system. Owners design it.

You are not just working inside a corporation. You are steering it.

Why Reimbursement Through a PC Is So Powerful

When you reimburse yourself under a compliant accountable plan, several good things happen at once.

Tax free treatment

Reimbursements that comply with an accountable plan do not show up as wages on your W2. That means no extra payroll taxes and no extra income tax on those amounts.

Corporate deductions

Your professional corporation deducts the reimbursements as ordinary and necessary business expenses. That reduces the net taxable income of the corporation.

Cleaner cash flow

Instead of paying many business costs from your personal account and waiting to sort them out at tax time, your PC reimburses you promptly. The business funds the expenses. You keep your personal cash flow intact.

Better audit posture

A written accountable plan, consistent documentation, and clear rules look much better under IRS scrutiny than ad hoc reimbursements. Owners do not leave this to chance.

All of this flows from one simple shift. You stop thinking like an employee. You start thinking like an entrepreneur.

Building Your Accountable Plan

Here is how you can build an accountable plan inside your PC.

Create a written policy

Spell out which expenses are covered, what documentation is required, and how quickly expenses must be submitted.

Adopt it formally

Have your PC approve the policy by resolution and record the effective date. This ties every reimbursement to a specific corporate decision.

Communicate it

Ensure you, your spouse, and any staff understand the rules. Clarity lowers friction and reduces mistakes.

Separate it from payroll

Reimbursements should be tracked separately from regular salary in your accounting and payroll systems. This keeps classification clean.

Review it annually

Adjust categories and per diem rates as your practice evolves. You are allowed to refine your system as your business matures.

What You Can Reimburse

Your accountable plan can cover any expense that is ordinary and necessary for your medical business. That can include:

• Travel for conferences or consulting work

• Mileage for business driving

• Meals in the context of business travel or meetings

• CME registration and materials

• Home office allocations when you meet the requirements

• Supplies and small equipment

• Software and subscriptions

• Licensing and board fees

• Professional dues and memberships

• Malpractice premiums paid personally

• Telemedicine and technology costs

• Marketing and website expenses

The key is to tie each expense to a concrete business purpose and document that purpose in your expense report.

When physicians see how many ordinary costs can be handled through an accountable plan, they stop asking, “Can I deduct this?” and begin asking, “What is the business reason for this?” That is owner language.

Using Per Diem Rates

Per diem reimbursements are another tool in the owner toolkit. Instead of chasing every meal and lodging receipt, you reimburse based on a standard daily amount.

You document:

• Where you went

• Why you went

• The dates you were there

Then you apply your chosen per diem rates while staying within federal guidelines.

This does not just reduce paperwork. It reinforces the idea that you are building systems for your own benefit. You are designing a way of operating that saves time, reduces friction, and keeps you compliant.

Case Study Dr Kellerman

Dr Kellerman had been operating as a PC for years but thought and behaved like an employee. He paid for many business related expenses personally. At the end of the year, he sent a stack of receipts and emails to his accountant and hoped the tax return would sort it all out. He did not feel like an entrepreneur. He felt like a clinician who just happened to file a corporate return.

The results showed it. His tax burden felt heavy. His cash flow was messy. He often used personal funds to float expenses the business should have covered. When we talked, he said, “I feel like the corporation is just paperwork. It is not actually helping me.”

We built his accountable plan from the ground up. We listed categories. We defined documentation. We created a simple process where he submitted expenses monthly. We separated reimbursements from payroll. We tied everything to a clear written policy.

Within a single quarter, things felt different. He stopped paying business expenses personally. His PC reimbursed him consistently. His W2 wages dropped a bit while tax free reimbursements rose. His corporate taxable income came down. But what impacted him most was not the math. It was the feeling.

He told me, “For the first time, I feel like I am running this corporation, not just filing taxes for it.”

That is the identity shift I want for every physician owner.

Identity Shift

This is why learning to think like an owner matters. When you see yourself as the person who designs the system, you stop accepting whatever happens by default. You start shaping your money flow with intention. An accountable plan is not just a tax formality. It is an owner level decision to stop leaving money on the table and start aligning your corporation with your goals.

If you want help thinking this way, start with:

• Accountable Plans for S-Corp Professionals Tax Efficient Reimbursements for a focused walkthrough on reimbursement structure

• Tax Deduction Guide for Independent Medical Professionals to broaden your understanding of what truly qualifies as a deductible business expense

• Mileage Reimbursement Maximizing Tax Benefits for Medical Professionals if your work involves significant driving between sites

Each of these resources reinforces the same message. You are not just a physician who happens to own a PC. You are a physician entrepreneur who can direct how money moves through your business.

Start Your Transition

If you are still thinking like an employee, this is your invitation to step into ownership. Your professional corporation is not just a legal structure. It is a platform. It can be designed well or poorly. The choice belongs to you.

If you want structured support as you make that shift, you can join the PEA Explorer Membership and connect with physicians who are learning to see their work, their corporation, and their income through a different lens.

When you learn to think like an owner, reimbursements are just the beginning. The way you view time, money, risk, and opportunity begins to change. And once that shift happens, you do not go back.
