my taxes were rejected for e filing due to Joint Occupancy on form 5695. Does anyone know what this is?

From IRS Instruction for Form 5695:

Joint occupancy.

If you occupied your home jointly with someone, each occupant must complete their own Form 5695. To figure the credit, the maximum qualifying costs that can be taken into account by all occupants for qualified fuel cell property costs is $1,667 for each one-half kilowatt of capacity of the property. The amount allocable to you for qualified fuel cell property costs is the lesser of:

The amount you paid, or

The maximum qualifying cost of the property multiplied by a fraction. The numerator is the amount you paid and the denominator is the total amount paid by you and all other occupants.

 

These rules don't apply to married individuals filing a joint return.

Example.

Ava owns a house with Bruce where they both reside. In 2024, they installed qualified fuel cell property at a cost of $20,000 with a kilowatt capacity of 5. Ava paid $12,000 towards the cost of the property and Bruce paid the remaining $8,000. The amount to be allocated is $16,670 ($1,667 x 10 (kilowatt capacity x 2)). The amount of cost allocable to Ava is $10,002 ($16,670 x $12,000/$20,000). The amount of cost allocable to Bruce is $6,668 ($16,670 x $8,000/$20,000).

If you have Form 5695 and claiming joint occupancy, the IRS will not be accepting these returns until 3/16/25. You can see this on this IRS site. The language you see below is from Row 39 of the Tax Year 2024 spreadsheet.

Taxpayers claiming Joint Occupancy on Form 5695 will have to file via paper if filing their return before the Form 5695 schema is updated in mid-March. This temporary limitation should only impact a subsection of Form 5695 filers.  For a preview of the TY24 draft form and instructions for Form 5695, please see the Draft tax forms on IRS.gov at https://www.irs.gov/draft-tax-forms. Submission of Forms 5695 that do not claim Joint Occupancy may be e-filed at the start of Processing Year 2025

Just wanted to say thank you to this thread and the Tax Experts advice.

I did want to pass along that we use desktop version of TT Premier.
Married filing jointly.

Original Fed & State return submission rejected.

I did try just unchecking the joint occupancy box directly on the 5695 form in Forms Mode.

Re-submitted and Fed + 2 States ALL rejected again.

Went into TT again and deleted the 5695 worksheet that TT also automatically created during the step-by-step process.

Resubmitted and ALL Fed & State returns were accepted. So glad I didn't have to wait for any TT update of their template. Form 5695 actually has a note near the top that if your joint return is your spouse do not check that Joint Occupancy box. Our tax situation does not have any splitting of 5695 credits.

Again appreciated the thread and maybe this helps with some frustration of others like me:-)
