If you’ve been around other contractors long enough, you’ve probably heard it all:
“Bro, you can deduct your entire truck payment.”
“Dude, just write off your fishing boat , say you took a client once.”
“I heard you can even deduct your dog as security!”
The contractor grapevine is full of legendary tax advice. Some of it’s funny. Some of it’s dangerous.
And believe it or not, some of it is actually true (with a few big “ifs”).
Let’s bust some myths and set the record straight.
Myth #1: “You Can Write Off 100% of Your Truck!”
Truth: Kind of… but not exactly.
Yes, you can deduct your work truck, but:
- It depends on business vs personal use.
- You must choose between standard mileage deduction or actual expenses.
- Section 179 or bonus depreciation may apply if it’s truly a business vehicle.
If that diesel monster is also your weekend camping ride, the IRS may ask a few questions.
Myth #2: “Just Deduct Your Boat as Marketing”
Truth: Almost always a bad idea.
In rare cases, client entertainment may allow partial deductions. But:
- IRS rules on entertainment deductions have tightened since 2018.
- Boat rides, golf outings, or sports tickets? Mostly not deductible.
- Meals? Maybe — but under strict conditions.
This deduction screams “audit bait”. Proceed with caution.
Myth #3: “Your Dog Counts as a Business Expense!”
Truth: Surprisingly, yes — but only sometimes.
If your dog is a trained, working guard dog at your shop or yard, you may deduct:
- Food
- Vet bills
- Training
But your friendly Golden Retriever at home? Not deductible.
You’ll need rock-solid documentation to claim this.
Myth #4: “Just Put Everything Under ‘Business Development’ — The IRS Won’t Care”
Truth: The IRS definitely cares.
- Every deduction must be ordinary and necessary for your business.
- Vague categories like “business development” raise red flags.
- Be specific: tools, marketing, licensing, education, etc.
Detailed, honest records keep you safe.
Myth #5: “You Can Deduct Your Entire Home as a Home Office”
Truth: Nope.
You can only deduct the part of your home used exclusively and regularly for business.
- Square footage method or simplified method.
- The space must be for business use only.
Your kitchen table or couch while watching Netflix?
Sorry, doesn’t count.
Myth #6: “My Buddy’s Accountant Said It Was Fine!”
Truth: Famous last words.
What works for someone else’s business might not work for yours.
Blindly following “contractor advice” is a fast track to IRS trouble.
