New Hampshire Tax Impact Calculator

New Hampshire imposes no state income tax on wages, salaries, capital gains, or retirement distributions, so divorce creates no state-level tax liability. Federal tax impacts still apply: your filing status changes to Single or Head of Household, alimony is non-deductible under the TCJA for post-2018 divorces, and retirement distributions without a proper QDRO face income tax plus a 10% early withdrawal penalty. Property transfers between spouses are exempt from New Hampshire's $0.75-per-$100 Real Estate Transfer Tax under RSA 78-B:2.

Your federal filing status depends on your marital status as of December 31 of the tax year. If your divorce is finalized by that date, you must file as Single or Head of Household — Married Filing Jointly is no longer available. Head of Household status requires maintaining a home for a qualifying dependent for more than half the year and provides a larger standard deduction ($22,500 vs. $15,000 for Single in 2025). During separation before the divorce is final, you may still file jointly or as Married Filing Separately.

For divorces finalized after December 31, 2018, alimony is not deductible by the payer and not taxable income for the recipient under the federal Tax Cuts and Jobs Act. New Hampshire has no state income tax, so alimony recipients face zero state tax burden regardless of when the divorce occurred. Pre-2019 divorce agreements retain the old federal rules where the payer deducts alimony and the recipient reports it as income. Under RSA 458:19, New Hampshire calculates alimony at 23% of the income difference between spouses.

Property transfers between spouses during divorce are generally tax-free at both federal and state levels. Under IRC § 1041, transfers incident to divorce carry no federal capital gains recognition — the receiving spouse assumes the original cost basis. New Hampshire imposes no state capital gains tax and exempts divorce-related real estate transfers from its RETT under RSA 78-B:2, saving each party $7.50 per $1,000 of property value. However, when the receiving spouse later sells the property, they will owe federal capital gains on any appreciation above the original basis.

Under federal IRS rules, the custodial parent — the parent with whom the child lives for the greater number of nights — claims the child as a dependent and receives the $2,200 child tax credit (2025). The custodial parent may release this claim to the noncustodial parent by signing IRS Form 8332. Only the custodial parent can claim Head of Household status, the Earned Income Tax Credit, and the dependent care credit regardless of any Form 8332 release. New Hampshire HB 322, if enacted, would allow the child support obligor to claim the child tax credit starting January 1, 2026.

Retirement accounts divided through a Qualified Domestic Relations Order (QDRO) transfer tax-free to the receiving spouse's own retirement account, with no federal income tax or 10% early withdrawal penalty. The New Hampshire Retirement System (NHRS) requires a QDRO for all public employee pension divisions and encourages parties to submit draft orders for preliminary review. IRA transfers incident to divorce do not require a QDRO — a direct custodian-to-custodian transfer pursuant to the divorce decree is tax-free. Without proper documentation, distributions face ordinary income tax plus a 10% penalty for recipients under 59½.

Under IRC § 121, each spouse can exclude up to $250,000 in capital gains from the sale of a primary residence, or $500,000 if filing jointly in the year of sale. You must have owned and lived in the home for at least 2 of the 5 years before the sale. New Hampshire imposes no state capital gains tax, and the RETT of $0.75 per $100 applies to the sale but not to transfers between divorcing spouses under RSA 78-B:2. A spouse who moves out before sale may still qualify for the federal exclusion if the divorce decree grants them a property interest.

Innocent spouse relief is a federal IRS provision under IRC § 6015 that protects you from liability for tax errors or fraud committed by your spouse on joint returns. You can request relief by filing IRS Form 8857 within 2 years of receiving an IRS notice (or up to 10 years for equitable relief). Because New Hampshire has no state income tax, innocent spouse issues involve only federal tax liability — there is no separate state-level innocent spouse relief program. Even if your divorce decree assigns tax debt to your ex-spouse, you remain jointly liable to the IRS until formal relief is granted.
