Important Notice — Amendment Required
Your Vehicle Deductions Need to Be Rebuilt
David — to file your amended returns for Tax Year 2020 and Tax Year 2021, the IRS requires a completed Form 4562 (Depreciation and Amortization) for every vehicle used in your business. This is not optional — without it, your vehicle deductions cannot be claimed on the amended Schedule C, and the IRS will disallow them entirely.

Your bank records show three vehicles connected to your business activity during 2020–2021: a Harley-Davidson motorcycle, a BMW, and a truck. Each vehicle needs its own worksheet. We need to know: what you paid for it, when you started using it for business, what percentage of its use was business-related, and how many miles you drove it for business each year.

The good news: if your truck weighs over 6,000 lbs (most trucks do), it qualifies for accelerated depreciation under Section 179 — potentially deducting the full purchase price in the year it was placed in service. That is one of the largest single deductions available to a self-employed person.

Complete one tab for each vehicle below. Enter what you know — leave blank what you don't. Kathy will reconcile everything against your bank records and follow up with specific questions.
Amendment gating: The 1040-X for TY2020 and TY2021 cannot be filed until these worksheets are complete and the vehicle deduction method (standard mileage vs. actual expenses) is confirmed for each vehicle. Standard mileage must have been used in the first year of business use to remain available in later years.
Why three vehicles matter: The IRS limits certain luxury vehicle depreciation (listed property rules under §280F). A Harley-Davidson is treated differently than a truck over 6,000 lbs. Each vehicle has its own deduction ceiling, its own mileage rate, and its own Form 4562 Part V entry. Getting this right on the amendment is what makes the deduction stick under audit.

Harley-Davidson — Important limitation: A motorcycle is classified as "listed property" under IRC §280F. This means (1) if business use is 50% or less, you must use straight-line depreciation only — no Section 179, no bonus depreciation; (2) you must have written mileage records to prove business use; (3) the IRS scrutinizes motorcycle business deductions heavily. Business purpose must be documented per trip.

Standard mileage rate: 2020 = 57.5¢/mile · 2021 = 56¢/mile. To use standard mileage for a vehicle, it must have been used in the first year of business use. If you claimed actual expenses in any prior year for this motorcycle, standard mileage may not be available.

Form 4562 Impact — TY2020 & TY2021 Amendments
This motorcycle deduction will appear on Form 4562, Part V (Listed Property) for each amendment year. Because a motorcycle is listed property, the IRS requires the business use percentage to be reported, and if use drops below 50%, depreciation recapture may apply. A mileage log is required — contemporaneous records, not a reconstruction. If you do not have a log, Kathy will help you build a reasonable reconstruction from your business activity records.

BMW — Luxury auto limits: Passenger vehicles (including most BMWs) are subject to annual depreciation caps under §280F. For 2020–2021, the first-year depreciation limit for a passenger auto is approximately $18,100 (with bonus depreciation) or $10,100 (without). If the BMW GVWR is over 6,000 lbs (some BMW SUVs qualify), it may escape the luxury auto caps — confirm the GVWR on the registration or door jamb sticker.

Truck opportunity: If your truck has a GVWR over 6,000 lbs (virtually all full-size pickups including F-150, F-250, RAM 1500, Silverado 1500) and was used more than 50% for business, you may be able to deduct up to $26,200 under §179 in the year it was placed in service — or 100% bonus depreciation if placed in service in 2020 or 2021. This is the largest potential vehicle deduction on your return.

Why This Worksheet Changes Your Amendments
A truck over 6,000 lbs placed in service in 2020 or 2021 with over 50% business use is one of the most powerful deductions in the tax code. 100% bonus depreciation was available in both years — meaning if you paid $35,000 for a qualifying truck and used it 80% for business, you could deduct $28,000 in the year of purchase. That single deduction could eliminate most of your remaining TY2020 or TY2021 liability after the income reconstruction. This is why Kathy needs the truck details immediately.
