17 Days Until Tax Day — The Expense You Forgot to Deduct
With 17 days left, millions of Americans are leaving money on the table. Here are the deductions you’re probably missing — and how to claim them before April 15.

The $1,200 You Didn’t Claim
According to the IRS, Americans overpay taxes by $1 billion annually simply by missing legitimate deductions. The average taxpayer leaves $400-$1,200 on the table every year.
Not because they’re hiding income. Because they forgot.
The Most Commonly Missed Deductions

🏠 Home Office (Simplified Method)
What it is: $5 per square foot, up to 300 sq ft ($1,500 max)

FAQ: Missed Deductions
Can I amend my return if I missed deductions?
Yes. File Form 1040-X within 3 years of the original filing date.
What if I don’t have receipts?
Bank/credit card statements work for expenses under $75. For larger amounts, request vendor replacement receipts.
Is the home office deduction an audit trigger?
Only if disproportionate to income. Simplified method ($5/sq ft) reduces audit risk.
How do I track mileage?
Use an app like BudgetX that logs every trip automatically with GPS.
