- I calculated my federal taxes by hand. I kept the cents in all of my calculations (I did not round to the nearest dollar at any point). Then I used these values to calculate my New York taxes.
- I submitted my federal taxes using Free File Fillable Forms and my New York taxes using the Department of Taxation and Finance website.
- My federal return was rejected because I forgot to include my Form 1040 Schedule D. I put my Form 8949 and Schedule D information into FFFF and resubmitted my federal taxes.
FFFF rounds all of its amounts to the nearest dollar, and somewhere in the chain of calculation my capital gains ended up $1 higher than [the rounded version of] what I had calculated. Hence, the capital gains and adjusted gross income (AGI) shown on my state return are $1 higher than the corresponding values on my federal return.
Do I need to amend my state tax return to reflect $1 differences in my capital gains and federal AGI that were caused by using different rounding methods? (I have verified that my state tax amount is the same with or without this dollar.)
