Side-by-side tax comparison between Alaska (no income tax) and Massachusetts (5% top rate, flat). See which state lets you keep more at every salary level, and how cost of living changes the picture.
Alaska has no state income tax, while Massachusetts uses a flat system with rates of 5% flat + 4% surtax >$1M. On a $100K salary, this creates a state tax difference of $5,000/year that Alaska residents simply don’t pay.
Massachusetts’s flat 5% rate means the gap scales linearly with income. At $200K, you’d save $10,000 by being in Alaska instead.
Alaska wins at 10 out of 10 salary levels tested. The advantage is consistent and significant across the income spectrum.
| Salary | Alaska | Massachusetts | Difference | Winner |
|---|---|---|---|---|
| $40K | $34,320 | $32,320 | −$2,000 | Alaska |
| $50K | $42,355 | $39,855 | −$2,500 | Alaska |
| $60K | $50,390 | $47,390 | −$3,000 | Alaska |
| $75K | $61,538 | $57,788 | −$3,750 | Alaska |
| $100K | $79,125 | $74,125 | −$5,000 | Alaska |
| $120K | $93,195 | $87,195 | −$6,000 | Alaska |
| $150K | $113,751 | $106,251 | −$7,500 | Alaska |
| $200K | $148,887 | $138,887 | −$10,000 | Alaska |
| $250K | $183,264 | $170,764 | −$12,500 | Alaska |
| $300K | $215,329 | $200,329 | −$15,000 | Alaska |
Take-home pay only tells part of the story. Alaska has a cost of living index of 127 while Massachusetts is at 118 (national average = 100).
The cost of living gap is moderate. After adjustment, $100K has purchasing power of $62,303 in Alaska vs $62,818 in Massachusetts. However, Massachusetts actually provides better purchasing power despite Alaska’s take-home advantage.
For a single earner at $100K filing jointly, take-home becomes $84,710 in Alaska and $79,710 in Massachusetts \u2014 a difference of $5,000. The gap remains similar regardless of filing status.
On paper, moving from Massachusetts to Alaska would save $5,000/year on a $100K salary, or $25,000 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $5,000/year savings is meaningful but probably not enough to justify a move on its own. However, combined with other factors like career growth, lifestyle preferences, or family proximity, it could tip the scale.
