There is an error in the office in home form. It pulls he wrong number from schedule C

The number that gets pulled into the calculation of the office-in-home Form 8829 line 8 is the tentative profit or loss from line 29 of Schedule C.  Sometimes this number needs to be adjusted by:

 

• Adding any capital gains from the business use of your home (from Form 8949 or 4797)
• Subtracting any business losses that are related to your business but not related to the physical use of your home

 

Due to these adjustments, the number that carries in to Form 8829 isn't always the same number as line 29 of Schedule C.  For more information, refer to Instructions for Form 8829 (2025).

 

If you are referring to a different calculation, let us know and we can help with any other questions.  

 

Can I take the home office deduction?

Where do I enter the home office deduction for my business?

 

 

The 2025 software is pulling line 28 from Schedule C  and putting it where line 29 is supposed to go.  To be more detailed your software is malfuctioning. It is taking the total expenses and putting it on form 8829 where Tentative profit should go. Thus causing the math to be wrong. Your software is also not allowing me to put in  Indirect expenses. This is a Major problem.
