I have used TurboTax for many years. It appeared to competently handle my consulting engineering work, investments and a single family rental property. I found the interface easy to use and liked the bringing data from the previous year into the next year's return. I did find TT's ability to pull data from financial accounts to be inconsistent, requiring me to carefully review with plenty of data entry.
We sold the rental last year, and found TurboTax Premier not up to the challenge of such a common transaction.
1. Depreciation on improvements had occurred ONLY the year the asset was installed. These were installed over 2 different years; new roof, new well, paved driveway.
2. I was unable to add those assets to the tax basis for the sale. Found I could NOT edit my attempts. Each try added new assets with no connection to the rental property.
4. TurboTax chat advised I clear my file and start over! I did this once but had the same problem.
Had I stayed with TurboTax, the sale would have been about $9k taxable profit
Bought TaxAct Premier for about $100. No troubles with the property sale.
The program also prompted me to the Carry Forward of disallowed losses section. This provided the significant taxable losses from the past to be reported.
Result was a small taxable loss on the sale, and a significant deduction for the carryovers.
I went from TurboTax's calculated tax bill of nearly $10k to a tax return of about $10k. Yes-almost $20k difference.
NOTE product scores are for TurboTax Premier.
