form 8829 Gross Income Limitation in simplified method wrong

tshock — Fri, 13 Feb 2026 21:12:34 GMT

Hi - I am having issue i cannot seem to figure out. On form 8829 the gross income limitation is not pulling correctly from my Schedule C. I have 50K in 1099 revenue, 10k of expense so a profit of 40K on line 29. But on form 8829, for the Gross Income Limit, it is only pulling in the expenses show it shows a profit of negative 10K. I have tried deleing and reentering to no avail. I also tried deleted schedule c and started over, I entered just the revenue, and then went to home office and selected simplified method, entered the needed info and it then allowed the deduction, showing profit of 50K, but then I entered the rest of my expenses, and the program changed profit to the same negative 10K (which is the total of non office expenses. Using desktop Mac. Please help.

Did you say that less than 100% of your income was earned from the Home Office? That is almost always what trigger it (and unfortunately, the way the law reads causes the bizarre result that you are seeing).

I am having the same issue. Line A of the Simplified Method Smart Worksheet is only picking up expenses, so it shows a negative number. My gross income is 16,000, my expenses 7,000 and my net profit is $9,000.

Line A which should be gross income minus expenses or $9,000 and the simplified method should be allowed.

However, Line A is picking up a -7000 and saying that is gross income and disallowing the simplified method.

This definitely appears to be a programming issue. And yes, I am saying that 100% of the income is from the home business use. Please advise!

For some reason, it seems to not be picking that up. Maybe try changing that to another number, then go back again and change it back to 100% (or even 99%) to see if that 'resets' it?

I am having the same issue with the wrong value being pulled into form 8829 from schedule C (line 28 instead of line 29 or 31). Did you figure out a solution? As someone else mentioned, it appears to be a programming issue.

Open form 8829. Go to Part II figure your allowable deduction.
Next go to line 8 calculation smart worksheet.

A enter date you began.
B. This is where you enter 100%.

Still say this is a programming issue since they ask this question in the data entry process but then ignore your answer.
Good luck.
