Thanks for clarifying that. What you have is a property improvement. Basically, here's how you'll treat things in TurboTax.
Your "new" setup for your entire property is different now. You won't enter the new construction as it's own separate entity in TurboTax at all. The basics for working this through the rental section:
- Type of rental is multi-family
- For "do any of theses situations apply...." select 2017 was the first year I rented this property, and I rent out a unit in a multi unit property where I live.
- YES, this property was rented all year. (Before you ask, read the "NOTE" on that screen.) then YES, it was rented at FMRV.
- NO, I do not have a home office.
- YES, I will enter total amounts and let TurboTax do the math.
- Enter the percentage of floor space being rented out. For example, if your primary residence is 1000 sq ft of floor space and the MIL house is 500 sq ft, that's a total of 1500 sq ft of floor space. So 33.3% of it is being rented out.
- No, *you* *did* *not* pay anyone more than $600 that would require you to issue them a 1099-MISC. (Requirement eliminated by congress for rental property owners, years ago.)
- Enter rental info my self.
Now on the review screen, what you just completed was the property profile. So that's where you go if you need to change/correct/update anything concerning what you've entered up to this point.
Work through and enter your rental income and expenses. These are the entries that matter:
Insurance - You will enter the total amount of insurance you paid and if necessary, add together what you paid for your home owners insurance on your residence, and the rental dwelling insurance policy on the MIL house, and enter that total.
For repairs and supplies, not one single penny of your construction cost goes here. Not a one. I am fully expecting those two to be a gif fat zero.
Utilities - enter what you paid for total utilities cost for the entire year. Include only those utilizes you share, which would be electric, gas, water, etc. Cable TV is a utility that you can include *provided* you actually do share it with the MIL house.
Enter the total amount of real estate taxes you paid in 2017. It does not matter if the tax bill for 2017 did not include the MIL house.
For reporting your mortgage interest, enter all 1098-Mortgage Interest Statements you receive on this property, in the exact amounts of each 1098.
Now you start the Assets/Deprecation section to enter/set up the property for depreciation. We'll step through this so I can explain with better clarity. So elect to start/update the Assets/Deprecation section.
- Select YES
- Select NO
- Select YES and on that same screen select NO for the special allowance. (This is not an option in your case, and if you select YES, it will be changed to NO later in the program weather you like it or not.)
- Select NO on improvements, and continue.
- Select Rental Real Estate Property, and continue
- Select Residential Rental Real Estate, and continue.
- On the "Tell us about this rental asset" here's the particulars
Your "cost" will be at a minimum, what you originally paid for the property when you purchased it all those years ago, "PLUS" what you paid for the MIL house you built out back, "PLUS" the cost of any other property improvements you may have done since you originally purchased the property all them years ago.
Your "cost of land" is how much of the "COST" entered above, is allocated to the land? Having built the MIL house *does* *not* *change* what you paid for the land when you originally purchased the property all those years ago.
The date purchased or acquired is the date you "originally" purchased the property all those years ago. Once all data entered, continue.
- Select that you purchased new, and under that select that you did NOT always use this item 100% for business. Then under that select that you used it for personal purposes, before you started using it for business.
For the date you started using it in the business, enter the earliest date that a renter "could" have moved in. This is generally the date you put the "for rent" sign in the front yard.
Now for that percentage it's asking for, this is based on "TIME" and not use. So if you started using it in your business on July 1st, that percentage would be 50%. If a renter could have moved in on Dec 1st, that percentage would be 8.49%. That would indicate that for all of 2017, the asset was used in the business 8.49% of the year.
After entering all data on this screen, continue.
Now you see the asset summary. If you'll select details and scroll down, you'll see I was telling the truth. Even if you did elect to take the SEC179 or special depreciation allowance, it shows zero for both on the summary detail screen.
