Quick Answer
Most states use a 183-day rule (roughly 6 months) to determine tax residency, but some states tax non-residents after just 1 day of work performed there. For example, New York taxes non-residents on income earned in the state regardless of time spent, while Florida has no state income tax at all.

How the 183-day rule works for state tax residency
Most states follow a 183-day rule for determining tax residency — if you spend more than half the year (183 days) in a state, you're generally considered a resident for tax purposes. However, this is just one part of a more complex calculation that also considers your "domicile" (permanent home) and other factors.
The 183-day test typically counts:
Example: $80,000 salary split between two states
Let's say you earn $80,000 annually and split your time between Texas (no state income tax) and California (top rate 13.3%). Here's how different scenarios play out:
Scenario 1: 120 days in California, 245 days in Texas
Scenario 2: 200 days in California, 165 days in Texas
States with different rules
Not all states follow the 183-day rule exactly:
Immediate taxation states: New York, Connecticut, and several others tax non-residents on any income earned in the state, regardless of days spent there. Work one day remotely for a NYC company while in New York? You owe New York tax on that day's wages.
No-day-count states: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming have no state income tax, so days spent there don't trigger tax obligations.
Hybrid approaches: Some states use both the 183-day test AND other factors like where you vote, hold a driver's license, or own property.
Key factors beyond day counting
What you should do
1. Keep detailed records of where you spend each day, especially if you're close to 183 days in any state
2. Track work locations — some states tax based on where work is performed, not just residency
3. Consider domicile factors — establish clear ties to your preferred tax state
4. Consult a tax professional if you're splitting time between high-tax and no-tax states

Key takeaway: The 183-day rule determines residency in most states, but some states tax non-residents immediately, and factors beyond day-counting (like domicile) also matter for your tax obligation.

Special considerations for remote workers
As a remote worker, you face unique challenges because your work location and residence location may be different states — and both can create tax obligations.
Convenience rule states like New York tax remote workers on wages earned for NY employers, even if you're working from another state "for your convenience." If your employer is based in NYC and you work remotely from Florida, New York may still tax that income.
Example: Remote worker splitting time
You earn $90,000 working remotely for a Colorado company:
Tax implications:
Your total state tax could range from $0 to $4,500 depending on how each state interprets your situation.
Tracking requirements for remote workers
1. Daily work location log: Track every day you work and where
2. Time zone records: Some states care about where you are during business hours
3. Equipment location: Where your primary workspace and equipment are located
4. Meeting locations: Whether you attend in-person meetings in specific states
Key takeaway: Remote workers must track both residency days and work location days, as some states tax based on where work is performed rather than just residency status.

Why day counting matters more at higher incomes
When you earn $200,000+ annually, state tax residency decisions can save or cost you $10,000-15,000 per year. California's 13.3% top rate versus Texas's 0% rate creates massive incentives for careful residency planning.
Advanced residency strategies
Domicile establishment: Beyond day counting, establish clear domicile in your preferred state:
Safe harbor rules: Some states offer safe harbors. For example, if you spend fewer than 30 days in New York and earn less than $14,000 there, you may avoid NY tax regardless of other factors.
Example: $300,000 earner with homes in NY and FL
Scenario A: NY resident (200+ days)
Scenario B: FL resident (under 183 days in NY)
This $19,500 difference makes careful day-counting extremely valuable for high earners.
Key takeaway: High earners can save $10,000-20,000 annually through strategic residency planning, making day tracking and domicile establishment crucial financial decisions.
