We bought a new residence in 2021 which includes a barn and acreage for our 3 horses. I have a horse business. In claiming the home office/separate structure for this business I put 100% of the structure is for work (storage of supplies and hay as well). When I input property tax to the expenses, the calculation took 100% of that and then my property tax deduction under personal deductions was totally skewed so I removed it from this business (we have 2 other home based businesses as well). The value of the barn is about $125K and I'm flummoxed by how to make this initial home office set up work!
