How do I expense a ministers expenses when he is the owner of the church as well

"he is trying to expense the repairs and supplies for the contractors"

If you are describing Building improvements, that isn't expense. It is Asset investment.

He "owns" a church, but that doesn't describe if he also owns Property or Real Estate.

It would be more helpful if you gave description and details. For instance, is this person renting a building and improving it to use for church services and operations?

Oh: A K-1 is a form that comes from an entity's tax return, such as 1120S (S corp) or 1065 (partnership). Nothing you described helps us understand what is the tax return or entity type of the Church? Perhaps the Church is filing using Form 990?

It's too bad that he owns the building personally, because a Church owning the property typically avoids property taxes. What it seems to be, is that this person has Property, and there is a Church using it, and he also works for that Church. Which means all of this should have been better thought out.
