Deductions & credits

I reviewed the articles mentioned in TurboTax after updating to the latest software.

 

I used $1 method too. I input the correct info in the first mortgage, and in the 2nd refinance mortgage, I input $1 at box 2. Then I computed and input the correct deductible interest on my own.

 

A small tip, if your first mortgage is more than $750k, and your mortgage date is before Dec 15, 2017, then your mortgage interest deduction limit is still $1MM, and this limit also applies to your 2nd refinanced mortgage.

 

I believe many customers who are not sensitive to numbers will not notice these errors and pay more taxes than required. I really hope TurboTax can make these special cases into their algorithm, so customers don't need to manually do these tricks!
