Anyone advise why the software is not calculating the bonus depreciation for a work truck purchased October 2025? Truck is over 6,000 lbs.

I read a post about responding yes to documenting personal use but I am not prompted for that question. Only asks about business use and if available for personal use. If I select yes or no to the personal use question the result is the same.

On the screen that says How do you want to enter your mileage for your vehicle, you should see an entry box for Total miles driven for all purposes and Milage driven for business and commuting. The miles driven for business have to be more than half of the total miles to be eligible for the bonus depreciation.

Thanks for the response.  The input mileage amounts are the same.  I file a Schedule C with my 1040 return.

Here is all the input.

FYI that the business code is 236100…residential construction

GMC Sierra 2500HD

Truck > 6,000 lb

10/2/2025 for when I started using the truck for work

Yes I own the Vehicle

Not available for personal use (did try with yes response as well)

Do have another vehicle for personal use (also tried with no response)

No, did not document miles because it is 100% business use. (Tried with yes as well)

No to did I track personal use (tried with yes as well)

Input total miles and business use miles with the same number

Zero for committing miles.

0-4 vehicles (do have a second truck that uses standard mileage rate)

Yes to see if actual expense give a bigger deduction

Input actual expenses incurred  (Gas, tires, insurance)

Yes to used by someone who owns business more than 5%

Truck not used for hire (taxi)

Vehicle was used when purchased (tried new as well)

No trade in

Input purchase date 10/2/2025 (same as date used for work)

Input purchase price

Did not input any other items  (Parking, tolls, etc.)

I tried deleting the truck and adding it again.  Same result.

The car and truck expense worksheet says the truck is not eligible for Economic Stimulus or section 179 property.

It should apply the section 179 $31,300 limit plus the 100% bonus depreciation.

I am using desktop version of Home and Business.

There are two issues which might be affecting the section 179 deduction on your tax return.  Both are discussed in this IRS publication.

Page 5 Line 5

If you are married filing separately, you and your spouse must allocate the dollar limitation for the tax year.

Page 5 Line 11 

The total cost you can deduct is limited to your taxable income from the active conduct of a trade or business during the year. You are considered to actively conduct a trade or business only if you meaningfully participate in its management or operations. A mere passive investor is not considered to actively conduct a trade or business.

We are filing a joint return and the profit definitely exceeds the cost of the truck.  Also responded yes to the question indicating the taxpayer operates the business and yes indicating the truck is used by someone who owns business more than 5 percent.

I solved the issue.  Initially reported the purchase date and date first used for business as the same day (10/02/2025).  I changed the date used for business to the next day (10/03/2025) and the software allowed me to fully depreciate the truck.
