Investment FAQs — New Hampshire
How are investment gains taxed in New Hampshire?
New Hampshire has no state income tax on capital gains. Investment returns are taxed federally only. At the federal level, long-term capital gains (assets held over 1 year) are taxed at 0%, 15%, or 20% depending on income. Short-term gains (assets held under 1 year) are taxed as ordinary income. New Hampshire adds no state tax — only federal capital gains taxes apply.
What is a good investment strategy for New Hampshire residents?
For New Hampshire investors, tax-advantaged accounts (Roth IRA, 401k) are especially powerful because they eliminate capital gains taxes entirely. Since New Hampshire has no state capital gains tax, taxable brokerage accounts are more attractive here than in high-tax states — you only pay federal capital gains rates.
How much should I invest per month in New Hampshire?
Most financial planners recommend saving 10–15% of gross income for retirement. In New Hampshire, a common starting point: 1) Contribute to your 401k up to the employer match (free money). 2) Max your Roth IRA ($7,000/year or $583/month in 2026). 3) Return to 401k up to the $23,500 annual limit. 4) Then invest in a taxable brokerage. Even $200/month at 7% annual return grows to $227,000 in 30 years — start now regardless of amount.
Is it better to invest in a Roth IRA or taxable brokerage in New Hampshire?
Almost always max the Roth IRA first (up to $7,000/year in 2026). Even in New Hampshire with no state capital gains tax, a Roth IRA eliminates federal capital gains taxes on all growth — a significant advantage for long-term investors. After maxing the Roth IRA and 401k, a taxable brokerage account gives unlimited investment flexibility.
What is the average stock market return for New Hampshire investors?
The US stock market return is the same regardless of state — state taxes affect your net return, not the market's gross return. The S&P 500 historical average: approximately 10–11% nominal annually, or 7% inflation-adjusted (real return). For a diversified portfolio: 5–6% real return is a conservative estimate. Use 7% for long-term projections — it's the standard used in financial planning and IRS 401k disclosures. With no New Hampshire state tax, your net returns on taxable investments are only reduced by federal capital gains taxes.
