probably not, it'd be like asking the IRS for information on taxpayers. You won't be able to get your neighbor's AGI over the past four years, but you probably could get some summary or overall statistics on the income of people in your city or state.

It's a felony for tax return information to be disclosed without authorization (e.g. 26 US Code § 6103), though it still happens sometimes.

I don't see anything in the bill language that restricts the disclosure, much less makes an unauthorized disclosure a crime.
