What Is IRS Form 2106?

Form 2106, Employee Business Expenses, allows employees to deduct ordinary and necessary expenses incurred while performing their job. The Vehicle Interest line (Part II, line 22) captures interest paid on a car loan used for work‑related travel.

How to Complete the Vehicle Interest Section

Follow these simple steps after clicking the “Fill out this form” button:

1. Enter your name, Social Security Number, and employer’s EIN in the header.
2. In Part II, locate Line 22 – Vehicle loan interest. Input the total interest paid during the tax year (see your loan statement).
3. Provide a brief description of the vehicle’s business use (mileage, percentage, etc.).
4. Attach supporting documentation (loan statements) when you file your return.

Common Mistakes & Tips for Accuracy

• Don’t mix personal interest with business interest—only the portion attributable to business use is deductible.
• Ensure the interest amount matches the figure on your lender’s year‑end statement.
• Round mileage to the nearest whole number; the IRS does not accept fractions.
• Double‑check that the form is signed and dated before submission.
