For the record, 1%er starts at ~$350k
Yes, say goodbye to most credits and deductions once you start making real money. I see so many bs posts about how much they make yet they claim they deduct student loan interests. Same with Roth IRA.
I agree with your assessment that most posters are talking out of their butts.
However, it depends if you are talking gross or AGI. With deductions, you can make significantly more gross without losing the ability to claim those deductions. In the following example, I am assuming married status, as that is what I file and I'm not looking up the single status numbers.
Example - These are deductions my wife and I make:
Max 401(k)s: +$34k ($33k last year, of course)
Mortgage Interest: +$10k
Qualified Educational Expense: +$4k
Medical Insurance Premium: +$2.5k
Additional ones you can take (that I know of off the top of my head):
Dependent Care: +$5k
Flex Account: +$5k
That's not even scratching the surface of tax deductions, and you are looking at over $60k in deductions not including student loan interest. RothIRA starts phasing out at $159k, so with these deductions, you could be grossing $219k and still be fully qualified for your Roth.
