Side-by-side tax comparison between Florida (no income tax) and Kentucky (3.5% top rate, flat). See which state lets you keep more at every salary level, and how cost of living changes the picture.
Florida has no state income tax, while Kentucky uses a flat system with rates of 3.5% flat. On a $100K salary, this creates a state tax difference of $5,000/year that Florida residents simply don’t pay.
Kentucky’s flat 3.5% rate means the gap scales linearly with income. At $200K, you’d save $10,000 by being in Florida instead.
Florida wins at 10 out of 10 salary levels tested. The advantage is consistent and significant across the income spectrum.
| Salary | Florida | Kentucky | Difference | Winner |
|---|---|---|---|---|
| $40K | $34,320 | $32,320 | −$2,000 | Florida |
| $50K | $42,355 | $39,855 | −$2,500 | Florida |
| $60K | $50,390 | $47,390 | −$3,000 | Florida |
| $75K | $61,538 | $57,788 | −$3,750 | Florida |
| $100K | $79,125 | $74,125 | −$5,000 | Florida |
| $120K | $93,195 | $87,195 | −$6,000 | Florida |
| $150K | $113,751 | $106,251 | −$7,500 | Florida |
| $200K | $148,887 | $138,887 | −$10,000 | Florida |
| $250K | $183,264 | $170,764 | −$12,500 | Florida |

Take-home pay only tells part of the story. Florida has a cost of living index of 100 while Kentucky is at 90 (national average = 100).
The cost of living gap is moderate. After adjustment, $100K has purchasing power of $79,125 in Florida vs $82,361 in Kentucky. However, Kentucky actually provides better purchasing power despite Florida’s take-home advantage.
For a single earner at $100K filing jointly, take-home becomes $84,710 in Florida and $79,710 in Kentucky \u2014 a difference of $5,000. The gap remains similar regardless of filing status.
On paper, moving from Kentucky to Florida 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.
