Furniture is a type of "equipment" that is used to generate income. It gets depreciated over 5 years.
If your cost is less than $2,500 per invoice, then you have the option of expensing it in that first year it's placed in service. In my opinion, expensing it may be the better option. It just depends.
For example, in my county equipment used on a recurring basis to generate income is subject to a county imposed tax every year it's in service. If it's depreciated, then it's listed as an asset which proves it's use. Any money saved by depreciating it, is lost when you pay the county "use tax" on it.
For those that have short term rentals, you are required to register them with the county where I live. So the county "knows" it's furnished. They're going to tax every single piece of furniture in the house every year, regardless of how it's reported on your tax return.
