I'm playing around with the NTA tool to see the optimal working hours for my part time wife, and I'm losing my mind trying to make sense of this. I make under 900万円, and my Japanese wife normally makes 130万円 (almost exactly but slightly over) each year. From the table listed on their site, I should only qualify for the 3万円 special deduction, however when I submit, it always gives me 38万円 special deduction. I have to push her salary up to 200万円 to get it to drop the deduction down to the 3万円. Is there something else factoring into this, or is there some bug with the tool's calculation?
