Understanding Each State
California
California has the highest top marginal state tax rate in the US at 13.3% (single filers over $1,000,000, including the Behavioral Health Services Tax surcharge), with progressive brackets starting at 1%. Despite high taxes, California's economy — tech, entertainment, agriculture — attracts top talent globally. Under OBBBA, the SALT deduction cap is $40,400 for 2026 ($20,200 if married filing separately), but it is cut by 30 cents for every dollar of MAGI above $505,000, down to a $10,000 floor — so the highest-income California itemizers see only partial federal relief.

North Carolina
This state uses a flat income tax rate, meaning the same percentage applies to all taxable income regardless of how much you earn. This simplifies tax planning but means there is no bracket benefit for lower earners. The effective rate is very close to the headline rate after deductions.
Tip: With a flat tax rate, your effective state rate is predictable and consistent. Focus tax reduction on pre-tax contributions (401k, HSA) and any state-specific deductions or credits available.
Key Comparison Points
Income tax structure: California has a progressive income tax (1% – 13.3%), while North Carolina has a flat income tax (3.99% flat).
Beyond income tax: State tax comparisons should also consider property tax rates, sales tax, and cost of living. A state with no income tax may have higher property or sales taxes that offset the savings.
SALT deduction cap: Under OBBBA, the 2026 federal SALT cap is $40,400, phasing out above $505,000 MAGI toward a $10,000 floor. This limits the federal tax benefit of living in a high-tax state, so the gross state tax difference remains close to the net difference for most earners — especially high earners inside the phaseout.
