All my taxes were submitted in March 2022. I am only now (July 2022) receiving the request from LA's Dept of Revenue for Form R-10606. I figured out several pieces of information this morning while looking at my LA return + MD return + NJ return. TurboTax's Smart Worksheet calculates the values to input Column 9 in R-10606. Column 8 is easy because this is the tax that I am liable for MD and NJ. Column 9 is calculated by multiplying the ratio (or "%" if one is using Excel) of income earned in Other State with LA Tax Line 11 in form IT-540. However, I have the same issue as the person (the Mississippi question above) who asked about Column 2. It is not clear from the R-10606 instructions which value should be the input. There are THREE possibilities: MD/NJ's Wages and Salary OR Gross Income OR Adjusted Gross Income (based on exemptions for MD or NJ). The LA R-10606 instructions say: "Enter the income taxable to the other state that is taxable to Louisiana." Looking at my R-10606 that HR Block's software filled out in 2020, the software entered the amount for Wages and Salaries, which to me, is incorrect. If I were to take a guess, shouldn't the amount be the Gross Income? I'm calling TurboTax tomorrow (Monday) when they open.
