Some tax deductions seem small—harmless, even. But in 2025, certain write-offs are catching the IRS’s attention more than ever. And if you’re not careful, that “harmless” deduction could be the very thing that triggers an audit.
Here are three deductions under increased IRS scrutiny this year—and what you need to know to stay compliant.
- Home Office Deduction
The home office deduction is 100% legitimate—if you follow the rules. Your space must be used exclusively and regularly for business. That means your guest room with a desk doesn’t qualify. But if you have a dedicated room, used only for work, you can and should take the deduction. Just make sure it’s clearly documented and calculated correctly.
Many business owners are afraid to claim this deduction because they’ve heard it’s a red flag. But the truth is, the IRS allows it when done right—and avoiding it out of fear just means you’re leaving money on the table.
- Meals & Entertainment
Grabbing coffee with a friend and calling it a “business meeting” won’t fly. The IRS is now closely reviewing meal deductions, especially those that seem personal. To qualify, the meal must be directly tied to business—think client meetings, working lunches, or meals during travel for business purposes. Keep records of who you met with, the business purpose, and receipts.
Only 50% of business meals are deductible in most cases—so make sure you’re calculating your deductions properly, not inflating numbers to boost write-offs.
- Vehicle Deductions
You can’t write off 100% of your car expenses unless the vehicle is used 100% for business. Even then, different vehicles follow different IRS rules. SUVs and trucks may be eligible for accelerated depreciation—but only if they meet specific business use thresholds. And no, your weekend trips don’t count. Log mileage. Track business use. Keep clean records.
The Real Problem Isn’t the Deduction
Taking the deduction isn’t what gets business owners in trouble—it’s taking it the wrong way. Poor documentation, mixing personal and business expenses, or relying on “what your friend does” opens the door for IRS pushback.
