How to read this

1. Payroll taxes are separate. Social Security and Medicare are wage taxes, not bracketed income taxes.
2. Brackets tax slices, not the whole paycheck. Moving into the next bracket only affects the dollars inside that band.
3. Pre-tax accounts shift taxable income. A 401(k), deductible IRA, and HSA can shrink the amount exposed to federal and state tax.
4. Family mode changes the UI assumptions. It swaps the calculator to married filing jointly, doubles the Maine personal exemption, and uses the family HSA limit.

Maine taxes and sales cheatsheet

Restaurants Prepared food Restaurant meals, takeout, and other prepared food are taxed at a higher Maine rate. 8%
Online shopping Usually still taxable If a seller does not collect Maine sales tax, Maine use tax can still apply at the same general rate. 5.5% use tax
Gas Usually fuel excise tax, not normal sales tax Gasoline is mainly hit through per-gallon fuel taxes that are built into the pump price. Per gallon excise tax
