The write-off is real. So are the ways to lose it.
A heavy SUV, pickup or van can come off your taxes in year one. But the rules are strict, and the IRS doesn't give partial credit.
No mileage log
Business use must be over 50%, and you have to prove it. Without a written log, an auditor can disallow the entire deduction.
The wrong form line
Vehicles are “listed property” and go in Part V of Form 4562, not Part II. Put it in both and you’ve doubled the deduction, which gets noticed.
The state surprise
California and many other states don’t allow bonus depreciation. Skip the add-back and your state return is wrong, by tens of thousands of dollars.
What's inside the workbook
Six short chapters, one worked example all the way through, and a spreadsheet that runs your numbers.

See exactly where every number goes
Most guides stop at “you can deduct it.” The workbook shows the full worked example: the deduction split into Section 179 and bonus depreciation, and the Form 4562 line each number goes on.
The calculator spreadsheet does the same for your vehicle: enter the price, business-use % and income, and copy the numbers onto the form.

QUESTIONIs this tax advice?▾
No. It’s a guide to the IRS rules (Publication 946, Publication 463, the Form 4562 instructions) with a worked example and a calculator. It helps you understand your return or have a much shorter, cheaper conversation with your tax professional.
QUESTIONMy CPA does my taxes. Do I still need this?▾
Your CPA files the form, but you have to bring the right facts: GVWR, placed-in-service date, business-use % and a mileage log. The workbook makes sure you have them, and helps you check the return before you sign it.
QUESTIONDoes it cover my state?▾
Chapter 6 explains how state add-backs work, with a full California example and a fill-in worksheet. The spreadsheet calculates the add-back for any state once you enter its Section 179 limit and whether it allows bonus depreciation, and the chapter shows how to look those up.
QUESTIONWhat if my vehicle is under 6,000 lbs?▾
Then the IRS luxury-auto caps apply and the year-one deduction is much smaller. The workbook is written for vehicles over 6,000 lbs GVWR.
QUESTIONI bought the vehicle earlier this year. Is it too late?▾
No. Any vehicle placed in service during 2026 counts on your 2026 return, which you file in early 2027. That’s when most owners use the workbook.
QUESTIONWhat format is it, and how do I get it?▾
A PDF workbook (about 14 pages, printable) and an .xlsx spreadsheet that works in Excel, Google Sheets and Numbers. The download link arrives by email within a minute of purchase.
QUESTIONWhat if business use drops below 50% later?▾
That triggers recapture. Chapter 5 explains it with the math, and the spreadsheet’s recapture tab shows what you’d owe for any year, so you can plan before it happens.
