I am making assumptions based on how the tax plan will affect an average tax payer. Those who live in states with higher state taxes will be disproportionately affected; MA isn't particularly high on state tax, so I didn't bring that up.
Here is a break down of how the tax plan will affect an average American household.
TL;DR:
Increase the standard deduction, but eliminate the personal exemption: -$1,450 in savings
Fewer tax brackets: -$175 in savings (but we think you can save more by doing your simplified taxes yourself instead of paying someone)
Reducing the property tax deduction: No effect for the typical household.
Limiting mortgage interest deduction: No effect for the typical household.
Child credit: +$600, at least until it sunsets in a few years.
Based on these numbers of a statistically average home, an average family will be $1,025 worse off than they were before the tax plan; this will only get worse when the individual relief sunsets and the corporate breaks continue. It also doesn't include the other provisions, such as eliminating the individual mandate which will balloon health premiums.
There is strong consensus of economists that this is a bad plan and balloon the debt, which will result in a financial crisis down the road. The GOP promise that it will increase growth to pay for itself will not play out, it has never played out that way all the other times we have tried it, going back to the 19th century. What this plan does look like is corporate asset stripping, which will absolutely ruin the economy.
