The Top 10 “Write-Off” Myths Doctors Still Believe

If you’re a high-income doctor, you’ve probably heard the same line a hundred times.

“Just write it off.”

It sounds like a cheat code. Buy something. Call it “business.” Pay less tax. Done.

Except real life does not work like that. The IRS does not care that your colleague’s cousin’s CPA said it was fine. The IRS cares about facts. Records. Purpose. And whether the expense is actually tied to earning income.

This post is a beginner-friendly breakdown of the top 10 write-off myths I still hear from physicians. I’ll keep it simple. No tax-speak. Just the stuff that saves you money and keeps your plan clean.

And yes, this is also part of what is tax planning. Because high-income tax planning is not about hunting random deductions. It’s about building a system that holds up when your income climbs and your life gets complicated.

Why “Write-Off” Thinking Trips Up High-Income Doctors

Most write-off myths come from one problem.

People treat taxes like a receipt scavenger hunt.

That approach feels productive. It also leaves money on the table because it ignores the bigger levers. Structure. Payroll. Retirement. Timing. Accountable plans. Entity strategy. The boring stuff that quietly changes the outcome.

If you want a clean baseline definition of what is tax planning, this guide lays it out in plain English: What Is Tax Planning for Physicians.

Here’s the mindset shift:

• Deductions matter

• A strategy matters more

• A strategy without records still fails

If you’re trying to do high-income tax planning without a system, it can feel like you’re always behind. You’re not alone. I see it all the time.

The Top 10 “Write-Off” Myths Doctors Still Believe

Let’s get specific. Here are the myths, and the real rule behind each one.

1) “If I buy it through my business, it’s automatically deductible.”

Nope.

Buying something with a business card does not make it a write-off. The expense still needs to be ordinary and necessary for your work, and you need records that support the business purpose.

Example:
You buy a laptop. You use it for charting, telemedicine, and CME. Great. That can be legit.
You buy a high-end gaming setup “for stress relief.” That story usually does not land well.

2) “A deduction means the IRS pays for it.”

This one sticks around because it feels good.

A deduction reduces taxable income. It does not refund the whole cost.

Simple math:
If you’re in a 37% federal bracket, a $1,000 deduction might save about $370 in federal income tax. Still helpful. Not free.

This is why high-income tax planning focuses on higher-impact moves, not just shopping for write-offs.

3) “My commute is deductible because I’m going to work.”

Commuting from home to your main workplace is usually personal. Not deductible.

Where it can change:

• You travel between two work locations in the same day

• You have a qualifying home office and travel from that office to a work site

• You travel for business purposes with documentation

If you’re a 1099 contractor and you’re unsure what counts, this is a solid reference: 1099 Contractor Tax Guide.

4) “I can write off meals if I talk about work.”

Talking about work is not a magic spell.

Business meals can be deductible, but you need:

• a real business purpose

• a record of who was there and what you discussed

• a reasonable expense

Example:
Dinner with a potential practice partner to discuss buy-in terms can make sense.
Weekly date night that includes a two-minute chat about staffing does not.

5) “My scrubs, white coats, and gym membership are deductions.”

Sometimes yes. Often no.

Uniforms can be deductible if they are required for work and not suitable for everyday wear. Scrubs can be tricky because plenty of people wear them casually.

Gym memberships are usually personal. There are edge cases. They’re not the norm.

6) “I can deduct everything in my home if I have a home office.”

Home office deductions are real. They are also specific.

The space needs to be:

• used regularly

• used exclusively

• used for business

That “exclusive” part is where most people get burned.

Example:
A dedicated room used only for charting and admin work is easier to support.
A dining table that also hosts family meals is harder.

7) “If I form an S corporation, I can write off more stuff.”

An S corporation can help with payroll and self-employment tax planning in the right case. It does not create brand-new categories of deductions.

It also comes with rules. The big one is reasonable compensation.

If you want the physician-focused breakdown, here: The Benefits of an S Corporation for Physicians.

This is where what is tax planning becomes practical. Entity choice is not a vibe. It’s math plus compliance.

8) “I can write off my spouse’s salary even if they don’t do much.”

If your spouse does real work, and you pay a reasonable wage for that work, this can be clean.

If your spouse does not do real work, the salary can turn into a problem fast.

A good standard is simple:

• job description

• track hours

• document tasks

• pay market-ish rates

If you want the bigger physician roadmap that ties these decisions together, this guide helps: Physician Tax Planning Guide.

9) “I can deduct my student loans as a business expense.”

Most physicians can’t.

Student loan interest deductions exist, but income limits often phase high earners out. Refinancing and repayment strategies matter, but they usually sit outside “business write-off” thinking.

If your debt feels like it’s colliding with your tax plan, this is a helpful perspective: Doctors and Debt Tax Plan.

10) “Itemizing means I’m winning.”

Itemizing is not a trophy. It’s just a method.

Some doctors itemize. Some take the standard deduction. Your goal is not “itemize.” Your goal is “pay what you owe, not more.”

If you want a clean explanation of how itemized deductions fit into planning, see: Guide to Itemized Deductions for a Better Tax Plan.

Common Mistakes That Turn “Write-Offs” Into Headaches

Most issues I see are not dramatic tax fraud. They’re normal people doing normal things… without clean habits.

Here are the biggest mistakes:

• No separation between business and personal spending
  Mixed accounts create messy books. Messy books create bad decisions.

• Weak documentation
  If you can’t explain it in one sentence and show a record, it’s fragile.

• Chasing deductions instead of strategy
  Buying things you do not need to “save tax” usually costs more than it saves.

• Treating social media advice as law
  A viral post is not a tax plan.

• Ignoring retirement strategy
  Retirement moves can be some of the best levers in high-income tax planning.

Quick Examples: What Clean “Write-Off” Thinking Looks Like

I think examples help because your real question is usually, “Is my situation normal?”

Here are a few that come up a lot.

Example 1: The 1099 moonlighting doctor

You moonlight at two facilities and do charting at home.

Clean approach:

• track mileage between facilities

• document home office if it qualifies

• separate bank account and card for 1099 income

• categorize expenses as you go, not in March

If you’re balancing W-2 and 1099, revisit: 1099 vs W2 for Physicians Tax Planning.

Example 2: The practice owner buying “equipment”

You buy devices, software, and furniture.

Clean approach:

• document business purpose

• keep invoices and payment records

• match the timing of purchases to cash flow and tax strategy

• review depreciation options with a real plan, not a guess

Example 3: The physician with a side consulting business

You attend a conference and meet future clients.

Clean approach:

• keep conference agenda

• log business meetings

• save receipts

• write down who you met and why it mattered

This is what is tax planning in real life. Not glamorous. Just organized.

FAQ: The Top 10 “Write-Off” Myths Doctors Still Believe

1) What is tax planning, in plain English?

It’s the process of making tax decisions on purpose, before the year ends, using the rules to reduce taxes legally. It includes entity strategy, retirement planning, timing income, timing expenses, and building clean records. For a deeper physician-specific explanation, see What Is Tax Planning for Physicians.

2) What’s the biggest difference between a deduction and a tax credit?

A deduction reduces taxable income. A credit reduces tax due dollar-for-dollar. High earners often focus on deductions and strategy because many credits phase out.

3) Can I deduct my car if I’m a doctor?

Sometimes. Commuting usually does not count. Business travel can count if you track it properly. Mileage logs matter.

4) Do I need an LLC to deduct business expenses?

No. An LLC is a legal structure, not a deduction generator. You can have deductible business expenses as a sole proprietor too, if they are legitimate and documented.

5) Is forming an S corporation always a good move for physicians?

No. It depends on income type, net profit, admin burden, and payroll requirements. Here’s a physician-focused overview: The Benefits of an S Corporation for Physicians.

6) What does “high-income tax planning” focus on?

It focuses on leverage points that scale with income, like retirement plan design, entity structuring, reasonable compensation, accountable plans, and timing strategies. It’s less about random write-offs and more about coordinated decisions.

7) Where should I start if I feel behind?

Start with clarity. What income types do you have. W-2, 1099, K-1, practice income. Then get a simple plan and a tracking system.
