Hi @TaxGuyBill, could you please explain more about Cost Seg, I mean for investment property to accelerate dep, client need to have a study? and can we file their tax return along with 3115?

When it works? I mean when the value of property is more than $.....

If rental income is about $25000 for a year and the amount of Dep is more than $25000, the loss is based on short-term rental can help the owner deduct as non-passive income, if he/she actively like a hotel performed!! Assume the owner has a big W-2 box1 and this loss a kind of reduce taxable income. I am right?  

Does Proseries handle this way of calculation for Dep?
