Navigating State and Local Tax (SALT) for Fully Remote and Hybrid Workers

Let’s be honest—the freedom of remote work is incredible. No commute, flexible hours, maybe even working from a beach house or a mountain cabin. But that freedom comes with a tangled, often overlooked, consequence: your state and local tax situation just got a whole lot more complicated.

Gone are the simple days of one state, one W-2. Now, you might live in one state, have your employer based in another, and log critical work hours from a third while visiting family. Each of those states might think they have a claim on a slice of your income. Navigating this maze isn’t just about filing; it’s about avoiding surprise bills, penalties, and a whole lot of stress.

The Core Principle: It’s All About Nexus and Domicile

Okay, first things first. You need to understand two key terms. They sound legalistic, but stick with me—they’re the map to this whole mess.

• Domicile: This is your permanent, legal home. The place you intend to return to. It’s where you vote, where your doctor is, where your kids go to school. States are very interested in this.
• Nexus: This is just a fancy word for “connection.” A physical presence—like working from your home office—creates a tax nexus for you and potentially for your employer. That’s a big deal.

Here’s the deal: Most states tax income based on source (where the work is performed) and/or residency (where you live). If your domicile is in New York but you work remotely for a California company from your Colorado condo for six months… well, you see the problem. Three states could come knocking.

The Hybrid Worker’s Tightrope

Hybrid schedules are perhaps the trickiest. You split time between a home office and a corporate location in another state. States often use a “convenience of the employer” rule versus “necessity” rule. Sounds abstract, but it has real teeth.

Take New York’s infamous rule. If your employer’s office is in NYC but you work from your home in New Jersey for your own convenience (not because your job requires it), New York may still tax 100% of your income. Connecticut and Delaware have similar rules. Nebraska just adopted one, too—a trend worth watching.

On the flip side, if you must work remotely because your job demands it—say, a server admin who must be on-site at a client’s data center in another state—that’s “necessity.” Different tax treatment may apply. The burden of proof, though? Usually on you.

Tracking Your “Work Days”: A Non-Negotiable Habit

You absolutely must track where you work, day by day. It’s tedious, I know. But think of it like a diet log for your finances—annoying but illuminating. Use an app, a spreadsheet, a calendar. Log:

• Workdays at your primary home.
• Days at the employer’s office.
• Any days worked while traveling (that vacation work session counts!).

This log is your first, best defense if a state revenue department has questions. Without it, you’re just guessing.

The Fully Remote Reality: Not So Simple Either

You’d think being 100% remote simplifies things. Not always. If your company has no physical presence in your state, they might not be set up to withhold taxes for it. This can lead to a shocking realization at tax time: you owe your home state a large lump sum because nothing was withheld all year.

Worse, some employers, unsure of multi-state compliance, might just withhold for their headquarters state anyway. That leaves you to sort out credits and payments. It’s a headache, honestly.

And what if you move? If you relocate from, say, Illinois to Florida mid-year, you trigger a part-year resident filing in both states. You need to know the exact date you established domicile in the new state. Pro tip: document everything—lease signings, driver’s license updates, utility bills. It’s evidence.

Common Pitfalls (And How to Sidestep Them)

Most people get tripped up in a few predictable areas. Let’s walk through them.

• The “Telecommuting Neighbor” Trap: Working a few days a week from your second home in a neighboring state? That likely creates a filing requirement there. Even a single day can, in some aggressive states.
• Withholding Assumptions: Assuming your HR/payroll department has your complex multi-state situation perfectly dialed in is risky. Have a conversation. Provide official documentation of your work location.
• Ignoring Local Taxes: It’s not just states. Cities like NYC, Philadelphia, and many in Ohio have their own local income taxes. Your remote work setup might not exempt you.
• Forgetting Reciprocal Agreements: Some neighboring states have agreements to avoid double taxation. Like D.C., Virginia, and Maryland. Or Pennsylvania and New Jersey. Check if you live/work in such a zone—it can save you a major hassle.

A Quick Glance at State Approaches

State Approach	What It Means	Example States
Convenience of Employer	Taxes income if remote work is for employee’s convenience, not necessity.	New York, Delaware, Nebraska*
Physical Presence	Taxes income for days physically worked in the state.	Most states, including California, Texas, Illinois
No Income Tax	No state-level personal income tax to worry about.	Florida, Texas, Washington, Nevada*

*Note: States like Washington & Nevada have no income tax but may have other taxes or high local taxes. Texas has no income tax but high property taxes. There’s always a trade-off, you know?

Actionable Steps to Take Control

Feeling overwhelmed? Don’t. Start here. Break it down.

1. Have “The Talk” with HR/Finance. Clarify your primary work location. Ensure withholding is set up correctly for your state of residence. Get it in writing.
2. Invest in a Tax Professional. This isn’t a DIY year. Find a CPA or tax advisor experienced in multi-state returns. The fee is worth the peace of mind and potential savings.
3. Document Everything. We said it before, but it’s that important. Domicile proof. Day log. Receipts. Keep it all for at least 3-4 years.
4. File, Even If You Think You Don’t Owe. Many states require a non-resident return if you earned income sourced there, even if the tax owed is zero after credits. Filing is the only way to square the ledger with the state.

Look, the way we work has fundamentally shifted. But state tax codes? They’re playing catch-up, and they’re often playing for keeps. The burden of compliance has subtly shifted onto our shoulders—the workers.

So the real question isn’t just about getting your return right this April. It’s about building a personal system for a work life that’s no longer anchored to a single place. It’s about viewing your work location as a key financial variable, as important as your salary or your 401(k) match. Because in this new world, your geography isn’t just about your lifestyle—it’s a line item on your tax return.
