Why Reciprocity Doesn’t Apply to Florida

Reciprocity agreements exist so that two states can agree not to tax each other’s residents. Florida has nothing to bring to that table. It doesn’t tax income at all — not wages, not interest, not capital gains. There’s no tax to waive, no deal to make.

This is actually good news for anyone living and working entirely in Miami. You pay federal income tax, and that’s it at the income level. No state return, no quarterly state estimates, no state withholding. But the picture shifts once your employer sits in a state that does tax income.

Working Remotely From Miami for a New York Employer

This is the scenario that trips up more Miami-based remote workers than any other. New York applies what’s called the “convenience of the employer” rule. If you work remotely from Florida for a New York-based company, and your remote arrangement is for your own convenience rather than a business necessity of the employer, New York taxes that income as if you were sitting in Manhattan.

Read that again. You’re in Miami. You never set foot in New York. And New York wants income tax on your wages.

The rule has survived legal challenges and the NY Tax Department enforces it aggressively. The only way around it is to show that your remote work from Florida is a requirement of the employer — meaning the employer has no office space for you in New York, or your job duties can only be performed from Florida. “I prefer working from home” doesn’t cut it.

Working Remotely From Miami for a California Employer

California doesn’t have a convenience-of-the-employer rule, and that matters. The Franchise Tax Board sources income based on where the work is physically performed. If you sit in Miami and do your work from Miami, California generally doesn’t tax that income — even if your employer is in LA and your paycheck comes from a California bank account.

There are exceptions. If you travel to California for meetings, client visits, or project work, the income earned during those days is California-source. The FTB has been known to audit remote workers and request travel calendars, badge-in records, and flight itineraries. Keep records.

Some California employers withhold CA tax from remote workers out of caution or because their payroll systems default to it. If that happens to you, you’ll need to file a California nonresident return (540NR) to get that money back. It’s not a small amount — California’s top rate is 13.3%.

What About Other Income-Tax States?

Most states follow a physical-presence rule similar to California’s. If you live in Miami and perform all your work from Miami, the employer’s state typically doesn’t tax you. The big exceptions:

• New York — convenience rule (discussed above)
• Connecticut — has its own version of the convenience rule, though narrower in scope
• Pennsylvania — follows physical presence for nonresidents, so Miami-based remote workers are generally safe
• New Jersey — physical presence, no convenience rule

If you have clients or projects in multiple states, each one has its own sourcing rules. A week of on-site work in Illinois creates an Illinois filing obligation, even if the rest of the year you’re working from your Brickell apartment.

Florida Residents Who Travel for Work

The no-income-tax benefit of Florida residency is real, but it only covers the income you earn while physically in Florida. Business travel to income-tax states creates exposure. Thirty days of work in California over the course of a year means 30/365 of your income is California-source. The same proportional calculation applies in most states that have an income tax.

Some states have de minimis thresholds — if you work fewer than a set number of days, you’re exempt from filing. Others, like California, have no such rule. Track your days carefully. A calendar with city-level location notes and matching hotel receipts or flight records is worth more than any tax strategy if you ever get audited.

Establishing Florida Domicile

If you recently moved to Miami from a high-tax state, make sure your domicile change is airtight. New York and California both audit people who claim to have left but maintain ties. New York uses a five-factor test: home, business, time, near-and-dear items, and family. Fail enough of those factors and they’ll treat you as a statutory resident even if your driver’s license says Florida.

Get a Florida driver’s license, register to vote in Florida, move your bank accounts, update your estate documents, and — critically — spend fewer than 183 days in your former state. Sloppy domicile changes are one of the most audited issues in multi-state tax.
