I noticed that the math is off when using the figures shown on the actual forms - for both Federal & State (CA in my case). The tax amounts owed (or refunded) are off by anywhere from $15 to $22. This seems to be beyond any rounding algorithms. Not sure if this exists elsewhere in TurboTax but now am suspect of the math in the product.
I agree. I went back to file an amended 2015 tax and noticed. From tax table here: https://www.irs.gov/pub/irs-prior/i1040tt--2015.pdf last page, it says 132805 taxable income is that times .25 minus 8412.5 which is 24788.75 but Turbo Tax Delus for that year recorded it as 24558. A difference of $230 difference. Unless I'm reading it wrong. 2014 Premiere was off by even more, over $300. WHat gives?
