State and Federal Taxes
Explains the key differences between state and federal income taxes, brackets, and filing rules for 2026.
TL;DR
- 01Understand that federal and state taxes are calculated and filed separately.
- 02Know your state's structure — nine states currently collect no income tax.
- 03Coordinate deductions across both systems to reduce your total tax bill.
Tips
- 01Use your state's official revenue website to verify current rates and forms before filing, since state tax laws change every year.
- 02Check your state's retirement exemptions, since many states exclude Social Security, pension, or IRA income from state taxable income.
- 03Consult a tax professional if you work across state lines regularly, since remote work can create tax obligations in multiple states.
Warnings
- 01Prior-state tax may still apply to income earned before a move, so file a part-year return in both the old and new states.
- 02States offer their own credits for education, energy efficiency, and dependents that differ from federal credits, so research your state's options every year.
- 03Missing a required quarterly estimated state payment can trigger penalties separate from any federal penalties, even if your federal taxes are fully paid.
Federal vs. State Tax Overview
The U.S. tax system requires most people to file both a federal return and a state return. Each has its own rates, deductions, and rules.
| Feature | Federal Taxes | State Taxes |
|---|---|---|
| Tax Authority | IRS (Internal Revenue Service) | State Revenue Departments |
| Tax Rates | Progressive (10%–37%) | Varies: flat, progressive, or none |
| Standard Deduction | $16,100 (single), $32,200 (MFJ) | Varies by state |
| Income Types Taxed | Wages, investments, business income | Some states exclude certain income types |
| Deductions and Credits | Federal rules apply nationwide | State-specific rules vary widely |
Federal tax applies uniformly across all states. State tax rules can differ significantly from one state to the next.
2026 Federal Tax Brackets
Federal income tax uses a progressive bracket system. You pay each rate only on the income within that bracket.
| Tax Rate | Single Filers | Married Filing Jointly |
|---|---|---|
| 10% | Up to $12,400 | Up to $24,800 |
| 12% | $12,401–$50,400 | $24,801–$100,800 |
| 22% | $50,401–$105,700 | $100,801–$211,400 |
| 24% | $105,701–$201,775 | $211,401–$403,550 |
| 32% | $201,776–$256,225 | $403,551–$512,450 |
| 35% | $256,226–$640,600 | $512,451–$768,700 |
| 37% | Over $640,600 | Over $768,700 |
The standard deduction for 2026 is $16,100 (single), $32,200 (married filing jointly), and $24,150 (head of household).
State Income Tax Structures
States use three main approaches to income tax.
- No income tax (9 states): Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Residents still owe federal tax.
- Flat tax states: A single rate applies to all income. Examples: Arizona (2.5%), Colorado (4.4%), Illinois (4.95%), North Carolina (4.5%), Utah (4.65%).
- Progressive tax states: Rates rise with income. Examples: California (1%–13.3%), New York (4%–10.9%), Oregon (4.75%–9.9%).
State tax rates generally range from 0% to 13.3% (California's top rate). Living in a high-tax state can significantly increase your total tax burden.
Planning for Both Obligations
- Consider state rates when relocating: Moving from California to Texas can save high earners tens of thousands of dollars annually.
- Check state retirement exemptions: Many states exempt Social Security, pension, or IRA income. This can reduce state taxable income significantly.
- Understand dual-state filing: If you live in one state and work in another, you may owe tax in both. Most states offer a credit to avoid double taxation.
- Watch for state-specific deductions: Some states allow deductions not available federally — such as 529 plan contributions or moving expenses.
- Track remote work rules: Working remotely for an out-of-state employer may create a tax obligation in your employer's state. Rules vary widely.
Common Pitfalls to Avoid
- Ignoring state obligations after moving: Prior-state tax may still apply to income earned before the move. File a part-year return in both states.
- Overlooking state-specific credits: States offer their own credits for education, energy efficiency, and dependents. Research your state's options each year.
- Missing estimated state payments: If your state requires quarterly estimated payments, missing them can trigger penalties separate from any federal penalties.
- Assuming federal rules match state rules: States often have different depreciation schedules, capital gains rules, and deduction limits.
