Workers in states with income tax who need to set up proper withholding
What state withholding forms do you need?
The state withholding form you need depends entirely on where you work, not where you live. If your job is in a state with income tax, you'll typically need to fill out that state's withholding form in addition to your federal W-4.
Key rule: You follow the withholding rules of the state where you physically perform your work, even if you live across state lines.
States that require no withholding forms
Nine states have no state income tax and require no withholding forms:
If you work in any of these states, you only need to complete a federal W-4.
Common state withholding forms by state
Example: Working in California
Let's say you're single, earn $75,000, and work in California. You'll need:
1. Federal W-4: Filed with HR for federal tax withholding
2. California DE-4: Filed with HR for state tax withholding
On your DE-4, if you're single with no dependents, you'd typically claim:
This results in about $312 per month in California state tax withholding on a $75,000 salary.
Special situations that require attention
Multi-state workers: If you live in one state but work in another, you may need forms for both states. For example, living in New Jersey but working in New York requires both NY IT-2104 and NJ NJ-W4.
Remote workers: Generally follow the rules of the state where your employer is located, but this varies by state. Some states tax based on where you live if you're working remotely.
High earners: Some states have additional withholding requirements for high-income earners. California, for example, has Mental Health Services Tax on income over $1 million.
How to get your state's form
1. Through your employer: HR should provide all required forms
2. State tax website: Every state publishes forms online
3. Payroll system: Many online payroll systems include state forms
What you should do
1. Identify your work state — not your home state
2. Check if that state has income tax using the list above
3. Get the correct state form from HR or the state website
4. Fill out both federal W-4 and state form before starting work
5. Update both forms if your situation changes (marriage, kids, income changes)
Use our W-4 optimizer tool to ensure you're withholding the right amount from both federal and state taxes.
Key takeaway: 41 states plus DC require separate state withholding forms in addition to your federal W-4. The form you need depends on where you work, not where you live, and each state has its own rules and allowances.
Key Takeaway: 41 states plus DC require separate state withholding forms in addition to your federal W-4, with the specific form based on your work location.
Common state withholding forms and their key features
| State | Form Name | Key Differences from Federal W-4 |
|---|---|---|
| California | DE-4 | Separate allowances for dependents |
| New York | IT-2104 | Different exemption calculations |
| Pennsylvania | REV-420 | Simple form with basic allowances |
| Illinois | IL-W-4 | Mirrors federal form closely |
| Texas | None | No state income tax |

High-income earners who may face additional state tax complications
High earner state withholding considerations
If you earn $150,000 or more, state withholding becomes more complex because many states have progressive tax rates that increase significantly at higher income levels.
California high earner example: On $200,000 income, California's top marginal rate is 9.3%, plus 1% Mental Health Services Tax on income over $1 million. Your DE-4 withholding may be insufficient if you don't account for this.
New York City triple taxation: High earners in NYC pay federal, state (up to 8.82%), AND city taxes (up to 3.88%). The IT-2104 form doesn't automatically optimize for this triple taxation.
States with additional high earner taxes
What high earners should do differently
1. Claim fewer allowances on state forms to increase withholding
2. Make quarterly estimated payments if withholding is insufficient
3. Consider safe harbor rules — pay 110% of prior year tax if AGI > $150K
4. Review withholding quarterly using paycheck calculators
Many high earners find their state withholding is inadequate and end up owing thousands at tax time. Consider working with a CPA to optimize your withholding strategy.
Key takeaway: High earners often need to manually increase state withholding or make estimated payments because standard allowances on state forms are designed for average incomes.

Workers with multiple W-2 jobs who need to coordinate withholding across employers
Multiple jobs create withholding complications
When you have multiple W-2 jobs, each employer calculates withholding as if it's your only job. This often results in under-withholding because:
Example: Two part-time jobs at $30,000 each ($60,000 total)
State withholding with multiple jobs
You need separate state withholding forms for each employer, but the coordination problem is worse:
Multiple job withholding strategy
1. Designate your highest-paying job as your "primary" job
2. Use standard allowances on the primary job's federal W-4 and state form
3. Claim zero allowances on secondary job(s) federal W-4 and state forms
4. Add extra withholding on forms if needed
Alternative: Use the IRS Tax Withholding Estimator to calculate exactly how much extra withholding you need, then add that amount to one job's W-4 and state form.
This prevents owing thousands in taxes across multiple states while avoiding massive over-withholding.
Key takeaway: Multiple jobs require zero allowances on secondary jobs' state forms plus potential extra withholding to avoid owing taxes in April.
Key Takeaway: Multiple jobs require zero allowances on secondary jobs' state forms plus potential extra withholding to avoid owing taxes in April.
