OVERVIEW
Despite New Jersey's reputation as a high-tax state and its much higher 10.75% top rate, New Jersey actually has a lower state income tax bill than Connecticut at every income level from $50,000 to $500,000 — $570/year less at $100,000, because New Jersey's brackets under $75,000 are unusually low (1.4% to 5.525%). Where New Jersey does live up to its reputation is property tax: at 1.88%, it's tied for the highest effective rate in the country, well above Connecticut's 1.54%.

FAQ

Frequently Asked Questions

Is New Jersey or Connecticut cheaper for taxes?

New Jersey has the lower state income tax bill at every income level checked, from $50,000 ($785/year less) to $500,000 ($1,590/year less), despite New Jersey's much higher 10.75% top rate. But New Jersey's property tax (1.88%, tied for highest in the US) is significantly above Connecticut's 1.54%, so homeowners — especially those with expensive homes — may find the total picture closer or even reversed.

Why is New Jersey cheaper than Connecticut despite New Jersey's reputation as a high-tax state?

New Jersey's income tax brackets under $75,000 are unusually low — 1.4% on the first $20,000 and just 5.525% up to $75,000 — while Connecticut has no standard deduction and a personal exemption that disappears entirely above $44,000 of income. New Jersey's high-tax reputation comes almost entirely from its property tax, which at 1.88% is tied for the highest effective rate in the country.

How do New Jersey and Connecticut property taxes compare?

New Jersey's average effective property tax rate is approximately 1.88% — tied for the highest in the United States — compared to Connecticut's 1.54%. On a $500,000 home, that's a difference of roughly $1,700/year (New Jersey ~$9,400 vs Connecticut ~$7,700), which can outweigh New Jersey's income tax advantage for homeowners.

Do New Jersey and Connecticut both tax Social Security?

No — New Jersey does not tax Social Security benefits at any income level. Connecticut exempts Social Security only below $75,000 AGI (single) or $100,000 (married filing jointly); above those thresholds, benefits become taxable. This makes New Jersey the more favorable of the two for higher-income Social Security recipients.
