Reply to comment by Ethoannalol in PSA: New York State tax brackets are not what they seem by PostPostMinimalist

Did you add all of lines 3, 4, and 9? Line 3 is the traditional calculation, but then you add 4 and 9.

Those magic constants on lines 4 and 5 are what get your total to the full marginal rate (at least, once you are 50k above the new bracket starting point). I’d share the full calculation here but am on my phone at the moment.

I don't think that's true. These numbers are relatively tiny and they certainly cannot have the effect that you are describing. All they do is slightly modify the overall dollar amount on which the tax debt is calculated using the usual bracket math.

Here's example, with WS 7 (first one of single). You can see how the adjustments make your highest marginal rate slowly apply to the whole income

Either do the math or don’t, I’ve done it and it comes out like I said, so I’ll only believe math which shows otherwise. I commented elsewhere on exactly how those numbers are calculated if you want to confirm.

The numbers are “small” because they are capturing marginal differences on top of the usual calculation. You’ll note they get much bigger as you move up the brackets (look at worksheet 4)
