STOP Claiming These 5 Deductions — IRS Crackdown Is Hitting Millions of Seniors in 2026

If your side business loses money 3 out of 5 years, the IRS reclassifies it as a hobby. Result: You pay tax on all income but cannot deduct any expenses.

Fix: Keep separate business bank account, maintain records, document profit motive clearly.

Space must be used exclusively and regularly for business — not personal use. Managing personal investments does NOT qualify as a business.

Fix: Only claim if you have an active trade or business with a dedicated exclusive space.

Rental property losses can only offset passive income — not Social Security, pension, or IRA withdrawals without meeting specific requirements.

Fix: Consult a CPA before claiming rental losses against ordinary retirement income.

You cannot deduct the value of your volunteer time — no matter how many hours or how skilled you are. This is explicitly prohibited under IRS rules.

Fix: Only deduct actual out-of-pocket expenses — mileage at 21¢/mile, supplies, required uniforms.

Only expenses exceeding 7.5% of AGI are deductible. Reimbursed expenses, cosmetic procedures, and gym memberships do not qualify.

Fix: Keep every receipt, every EOB from insurance. Only claim unreimbursed qualified medical expenses per IRS Publication 502.
