Hiring Your First Employee in Another State? Here's What Founders Need to Know

You just found the perfect engineer. They live in Colorado. Your startup is incorporated in Delaware, and your cofounder works from California.

No problem. You're remote-first.

Except hiring employees in another state can create new tax obligations for your startup, even if you don't have an office there.

Depending on the state, you may need to register your business, set up payroll withholding, pay unemployment taxes, and file additional state tax returns.

Here's what founders need to know before making that first out-of-state hire.

Why Does Hiring an Employee in Another State Create Tax Obligations?

The short answer is state tax nexus.

Nexus is the connection between your business and a state that allows the state to impose certain tax obligations.

You don't necessarily need an office, customers, or revenue in a state to establish nexus. In many cases, having just one employee working there is enough.

For example, say your Delaware C-Corp hires a full-time remote employee in Colorado.

Even if your company operates entirely online, that employee's presence may trigger Colorado employer registration, payroll withholding, unemployment insurance, and business tax filing requirements.

And these obligations aren't limited to profitable startups.

A pre-revenue company can still have state tax responsibilities because it employs someone there.

The specific rules vary by state and tax type, so hiring someone remotely doesn't automatically mean you'll owe every state tax. But it does mean you need to review your obligations before their first paycheck.

What Tax Registrations Do Startups Need for Out-of-State Employees?

Hiring across state lines can involve several registrations, sometimes with different agencies.

Here are the most common requirements founders should review.

1. State Payroll Withholding Registration

Most states with an individual income tax require employers to withhold state income taxes from wages earned by employees working there, subject to state-specific rules and exceptions.

That typically means registering with the state's department of revenue or equivalent tax agency.

Once registered, your startup may need to:

• Withhold the appropriate state income tax from employee paychecks.
• Remit those taxes according to the state's deposit schedule.
• File periodic withholding returns.
• Issue the appropriate state wage information on employee tax forms.

Some states also have local income taxes, which can create additional withholding requirements.

Importantly, the employee's physical work location matters. Your Delaware incorporation doesn't determine where all employee wages are taxed.

2. State Unemployment Insurance Registration

Employers generally must pay state unemployment insurance (SUI) taxes on covered employee wages.

When you hire your first employee in a new state, you may need to register with that state's unemployment insurance agency.

Your responsibilities can include:

• Obtaining a state unemployment insurance account number.
• Paying unemployment insurance taxes at the assigned rate.
• Filing quarterly wage reports.
• Monitoring changes to your tax rate as your company grows.

For employees working across multiple states, special rules determine which state receives unemployment insurance contributions.

3. Foreign Qualification and Business Registration

Payroll registration isn't always the only requirement.

Depending on the employee's activities and the state's rules, your startup may also need to register with the Secretary of State as a foreign entity.

Despite the name, foreign qualification doesn't mean your company operates internationally. It means your business was formed in one state but is authorized to conduct business in another.

For example, a Delaware C-Corp conducting business in another state may need to register there.

Foreign qualification can introduce additional requirements, including registered agent fees, annual reports, and other state compliance obligations.

However, tax nexus and foreign qualification are separate legal concepts. Having a remote employee doesn't automatically establish every type of registration requirement.

4. State Corporate Income and Franchise Tax Filings

Here's the obligation founders often miss.

An employee's presence may create nexus for state corporate income or franchise taxes, even when the company doesn't have an office in that state.

Depending on the state's rules, your startup may need to file a corporate tax return or pay applicable minimum taxes.

Some states have minimum franchise taxes or filing requirements that can apply even when a startup is operating at a loss.

Others use different nexus thresholds, exemptions, and tax calculation methods.

That's why it's important to review corporate tax obligations separately from payroll registration.

Fondo's TaxPass helps startups manage federal and state corporate tax filings as they expand into new states.

What Other Compliance Requirements Can Remote Hiring Trigger?

State tax registrations are only part of the process.

Depending on where your employee works, your startup may also need to address:

• New-hire reporting: Report newly hired employees to the appropriate state agency within its required timeframe.
• Workers' compensation insurance: Obtain coverage when required under state law.
• Paid leave programs: Register for and contribute to applicable state paid family, medical, or disability leave programs.
• State labor laws: Follow applicable wage, overtime, paid sick leave, and employee notice requirements.
• Local payroll taxes: Register for additional withholding or employer taxes in certain cities or municipalities.

These requirements differ significantly between states.

The takeaway? Don't assume that because your payroll platform supports an employee's state, your company has completed every registration needed to employ them there.

Does Payroll Software Handle Out-of-State Tax Registrations?

Payroll platforms like Gusto, Rippling, and Deel can simplify multi-state payroll.

Depending on the provider and your plan, they may calculate withholding, process payroll tax payments, file payroll returns, and assist with employer registrations.

But payroll software doesn't necessarily handle everything.

Your startup may still be responsible for:

• Registering or authorizing the provider to register for required state tax accounts.
• Determining whether foreign qualification is necessary.
• Identifying corporate income and franchise tax filing obligations.
• Managing state annual reports and other business compliance requirements.
• Ensuring employee work locations and tax information remain accurate.

Payroll tax compliance and corporate tax compliance are related, but they're not the same thing.

A payroll provider may handle employee withholding without preparing your startup's state corporate income tax return.

That's where having a tax partner who understands venture-backed startups becomes valuable.

Your Out-of-State Hiring Tax Checklist

Before your first remote employee starts, work through these steps.

Task

• Confirm work location
• Review state nexus
• Check business registration
• Register for payroll withholding
• Register for unemployment insurance
• Review employment requirements
• Configure payroll
• Update your compliance calendar

‍

What to Check

• Identify where the employee will physically perform their work
• Determine whether the hire creates corporate tax or other state obligations
• Determine whether foreign qualification is required
• Obtain applicable state and local withholding accounts
• Set up SUI accounts and confirm applicable coverage
• Check workers' compensation, paid leave, and new-hire reporting
• Confirm withholding, employer taxes, and filing responsibilities
• Track recurring payroll, corporate tax, and annual report deadlines

Some registrations must be completed before payroll begins. Others have deadlines tied to hiring, first wages, or specific filing periods.

It's worth reviewing these requirements before sending an offer, rather than discovering them after your first payroll run.

What Happens if You Hire an Out-of-State Employee Without Registering?

Missing a state registration doesn't necessarily create an immediate problem.

But it can become one later.

Depending on the state and the obligation, your startup could face:

• Late registration or filing penalties.
• Interest on unpaid taxes.
• Backdated payroll or corporate tax filings.
• Additional administrative work to correct previous reporting.
• Compliance issues that surface during fundraising or due diligence.

For early-stage startups, the bigger problem is often the time spent cleaning everything up.

You don't want to discover missing state tax returns while preparing for a Series A or responding to an investor's due diligence request.

If you've already hired remote employees without reviewing your state registrations, start by identifying where they work, when they started, and which registrations and filings have been completed.

Then work with your tax advisor to determine what needs to be corrected.

Frequently Asked Questions About Hiring Employees in Another State

Can a Delaware C-Corp Hire Employees in Other States?

Yes. Delaware C-Corps can hire employees throughout the United States. However, employing someone in another state may trigger payroll registration, unemployment insurance, corporate tax, and business registration requirements in that state.

Do You Have to Register Your Business in Every State Where You Have an Employee?

Not necessarily. Requirements depend on the state's laws and the employee's activities. Payroll tax registration, corporate tax nexus, and foreign qualification are separate obligations that must be evaluated individually.

Does One Remote Employee Create State Tax Nexus?

It can. In many states, one employee working remotely can establish sufficient physical presence for certain state tax obligations. The exact consequences depend on the state, the employee's work, and the tax involved.

Who Pays State Income Taxes for Remote Employees?

Employees generally owe applicable individual income taxes based on state residency and where they perform their work. Employers are responsible for withholding and remitting taxes when required. Some states have reciprocal agreements or special rules for employees working across state lines.

Does a Startup Owe State Taxes if It Has No Revenue?

Potentially. Some state filing requirements and minimum taxes can apply even when a startup is pre-revenue or operating at a loss. Having an employee in a state may create obligations regardless of profitability.
