Tax Impact of Relocation

Moving from a high-tax state (California, New York) to a no-tax state (Texas, Florida) can save 10%+ of income annually. However, no-tax states often have higher property taxes or sales taxes to compensate. Consider total tax burden, not just income tax.

Worked Through the Brackets

On $75,000 of gross income, filing single, taking the $14,600 standard deduction — so $60,400 of taxable income:

Bracket	Range	Income taxed here	Tax
10%	$0 – $11,600	$11,600	$1,160
12%	$11,600 – $47,150	$35,550	$4,266
22%	$47,150 – $100,525	$13,250	$2,915
Total			$8,341

That is a 11.1% effective rate against a 22% marginal rate. The two answer different questions: the marginal rate is what the next dollar costs, and it is the one that decides whether a 401(k) contribution or an extra shift is worth it. The effective rate is what you actually paid, and it is the one to budget against.

The Same Income, Different Sources

Source	Federal tax on it
Wages (above)	$8,341
Self-employment profit	$8,341 income tax plus $10,597 SE tax
Long-term capital gain of $10,000	$1,500 at 15%

Where income comes from changes the bill more than how much of it there is. A self-employed filer at this level pays roughly $10,597 that an employee never sees, because there is no employer paying the other half of FICA.
