FAQ

Frequently Asked Questions

Is North Carolina or Connecticut better for taxes?

North Carolina is cheaper on income tax at every level — $1,269/year less at $100,000, growing to $11,809/year at $500,000 — and also has a much lower property tax (0.66% vs Connecticut's 1.54%) plus no estate tax. Connecticut's advantage is proximity to New York City's job market and typically higher salaries in finance and professional services, which can outweigh the tax gap for high earners in those fields.

How much does North Carolina save versus Connecticut at high incomes?

The gap widens sharply as income rises: at $500,000, a North Carolina resident pays $19,441 in state income tax versus $31,250 in Connecticut — a difference of $11,809/year. This is because Connecticut's brackets climb to 6.99% while North Carolina's flat 3.99% rate never increases.

Does Connecticut or North Carolina have an estate tax?

Connecticut has a 12% flat estate tax on estates above the federal exemption threshold (approximately $13.61-15 million for 2026). North Carolina has no state estate tax or inheritance tax at all. For high-net-worth families, this is a significant additional advantage for North Carolina beyond the income and property tax savings.

How do property taxes compare between North Carolina and Connecticut?

North Carolina's average effective property tax rate is approximately 0.66%, less than half Connecticut's 1.54%. On a $400,000 home, that's a difference of roughly $3,520/year (North Carolina ~$2,640 vs Connecticut ~$6,160) — a substantial addition to North Carolina's income tax savings for homeowners.
