Tax moves that matter most for New Hampshire
New Hampshire has no state income tax, so SALT cap concerns are limited to property tax. Optimization focus shifts to federal: 401(k), Mega Backdoor Roth, HSA, S-Corp election for self-employed.
At nearly twice the national average, property tax dominates the SALT cap calculation in New Hampshire. Bunching property tax payments (paying 18 months in one calendar year) can sometimes push you above the standard deduction in alternating years.
At net SE income above ~$80k-$100k, electing S-Corp typically saves $5k-$15k/yr in self-employment tax — the math is largely federal but affects New Hampshire state tax via PTET (if applicable).
If you have 1099 income, Solo 401(k) lets you contribute up to $70,000/yr (2025) — far more than SEP-IRA in most cases. Reduces both federal and New Hampshire state income tax.
