No more deductions for any of those things. If you were keeping track, that’s no more tax writeoffs for moving expenses related to work (unless you’re in the military), no more deductions for tax preparation fees, work-related expenses not reimbursed by an employer, or cost of your home office setup. No more being able to deduct any state or local taxes from your federal tax return. No more deducting student loan interest and certain tuition expenses. No more deductions based on sustainable construction practices, which will discourage businesses from doing them.
This means that WAY more of your income is subject to taxation under this plan. This is a regressive tax, meaning that it impacts the wealthy far less than it would everyone else.
