Federal vs Payroll vs State and Local Taxes
A clear breakdown of what each tax funds and why your total tax burden can vary widely.
Your tax bill is a mix of different systems that do very different things. Understanding those buckets helps you see where strategies help the most.
Key Takeaways
- Federal income tax funds the general federal budget.
- Payroll taxes fund Social Security and Medicare and are mostly flat up to caps.
- State and local taxes vary widely and often drive big effective rate differences.
Federal Income Tax
This is the progressive tax most people think of. It funds the general federal budget — everything from defense to national parks to federal agencies.
Key characteristics:
- Progressive brackets: 10%, 12%, 22%, 24%, 32%, 35%, 37% (2026).
- Standard deduction: $15,400 (single), $30,800 (MFJ), $23,100 (HoH) for 2026. See the standard deduction glossary for context.
- Deductions and credits reduce it: Most tax strategies (retirement contributions, HSA, charitable giving) reduce federal income tax.
Federal income tax is what people think of when they say “I’m in the 24% bracket.” If you want to see how that compares to your true burden, review marginal vs effective tax rates.
Payroll Tax and FICA
Payroll taxes fund Social Security and Medicare. These are less progressive and apply to wages and self-employment income. They can be a large portion of taxes for middle-income households.
Social Security Tax (OASDI)
- Employee rate: 6.2% (employer pays another 6.2%)
- Self-employed rate: 12.4%
- Wage base cap (2026): $183,000
Once you earn more than $183,000, you stop paying Social Security tax on additional wages. This makes payroll taxes regressive at high incomes. For a deeper explanation, see the payroll tax and FICA glossary.
Medicare Tax
- Employee rate: 1.45% (employer pays another 1.45%)
- Self-employed rate: 2.9%
- No wage cap: You pay Medicare tax on all wages, no matter how high.
Additional Medicare Tax (NIIT Surtax)
High earners pay an extra 0.9% Medicare tax on wages above:
- $250,000 (MFJ)
- $200,000 (Single)
- $125,000 (Married Filing Separately)
This brings the top Medicare rate to 3.8% for employees (or 4.7% self-employed when combined with the base rate). See the Medicare surtax glossary for thresholds.
For investment income, there’s also a Net Investment Income Tax (NIIT) of 3.8% on investment income above the same thresholds. See our NIIT guide for details.
State and Local Taxes
State income taxes, city taxes, and local levies can add significant burden. Strategies like relocation or state-specific deductions can have a large impact.
State income tax rates vary wildly:
- No income tax: Alaska, Florida, Nevada, New Hampshire (wages), South Dakota, Tennessee, Texas, Washington, Wyoming.
- Flat tax states: Illinois (4.95%), Colorado (4.40%), many others.
- Progressive tax states: California (up to 13.3%), New York (up to 10.9%), New Jersey (up to 10.75%).
Local taxes can add another layer:
- New York City residents pay an additional 3.078%-3.876%.
- Philadelphia wage tax: 3.79% (residents) or 3.44% (non-residents working in the city).
- Many cities and counties levy their own income taxes.
If you live in California and New York City, your top marginal rate (federal + state + local + payroll) can exceed 50%.
Comparing the Three: A Middle-Income Example
Let’s look at a single filer earning $80,000 in wages living in California:
| Tax Type | Calculation | Amount |
|---|---|---|
| Federal Income Tax | Taxable income after $15,400 standard deduction | ~$10,000 |
| Social Security | 6.2% × $80,000 | $4,960 |
| Medicare | 1.45% × $80,000 | $1,160 |
| California State | ~5.5% effective rate after deductions | ~$4,000 |
| Total Tax | Federal + FICA + State | ~$20,120 |
| Effective Rate | $20,120 / $80,000 | 25.2% |
Notice that payroll taxes ($6,120) are more than half of the federal income tax bill. For middle-income earners, payroll taxes are a huge part of the burden.
Comparing the Three: A High-Income Example
Now let’s look at a married couple earning $500,000 in wages living in New York:
| Tax Type | Calculation | Amount |
|---|---|---|
| Federal Income Tax | Taxable income after $30,800 standard deduction | ~$115,000 |
| Social Security | 6.2% × $183,000 (capped) × 2 earners | $22,692 |
| Medicare | 1.45% × $500,000 | $7,250 |
| Additional Medicare | 0.9% × ($500,000 - $250,000) | $2,250 |
| New York State | ~6.5% effective rate | ~$30,000 |
| Total Tax | Federal + FICA + State | ~$177,192 |
| Effective Rate | $177,192 / $500,000 | 35.4% |
High earners pay less Social Security tax as a percentage of income (due to the wage cap), but pay much more federal income tax and state tax.
Why This Matters
When you see a recommendation in sharper.tax, it is anchored to a specific tax type. For example:
- Retirement contributions (Traditional 401k, IRA) reduce federal income tax and state income tax, but not payroll taxes.
- Self-employment planning (S-Corp election) targets payroll tax by converting wages to distributions.
- Relocation strategies target state tax by moving to a no-income-tax state.
- HSA contributions reduce federal income tax, payroll tax, and state income tax — making them one of the most powerful tools available.
Use this framework to decide which strategies matter most for you.
To see how different tax types apply to high earners, check self-employment tax explained. For HSA strategy, see HSA vs FSA comparison.
