Navigating the Complex Tax Implications of Remote Employees

Remote work has reshaped the way businesses operate in 2025. With more employees working from home—often across state lines—this new reality is making payroll management trickier than ever. For business owners and HR professionals, one of the most overlooked challenges is staying on top of tax implications when your team is spread out.

One common mistake we see at Lift HCM? Employers enter a remote employee’s home address, but forget to set their actual work location—defaulting it to the business’s home state. This simple oversight can result in Incorrect State Unemployment Insurance (SUI) tax payments, Improper state income tax withholding, Unexpected tax liabilities in multiple state, Late payment penalties and time-consuming amendments

This article provides a simple framework to help you avoid these mistakes and ensure your business is tax-compliant when hiring remote employees.

📋 QUICK START: Remote Employee Tax Compliance

1. Always update BOTH employee home address AND work location in your system
2. Register with state tax authorities before your employee starts work
3. Configure payroll for the correct work state's income tax and unemployment insurance
4. Implement a process for employees to report work location changes
5. Schedule quarterly audits of work locations in your payroll system

The Most Common Remote Work Tax Mistake

The scenario: Your business is based in Illinois. You hire a remote employee who lives and works from their home in Colorado. During onboarding, you enter their Colorado home address but fail to update their work location, which defaults to your Illinois office.

The problem: Your payroll system is now withholding Illinois state income tax and paying Illinois SUI taxes for an employee who should be subject to Colorado taxes.

The consequences:

• You've created potential tax liabilities in two states
• You're paying unemployment insurance in the wrong state
• You may face penalties for late payment of Colorado taxes
• The employee may face complications with their personal tax return
• Your business may need to file amended returns and pay interest

📌 Pro Tip: Always ensure that both the home address AND work location are correctly updated in your system for every remote employee. This simple step prevents most remote work tax headaches.

Federal Tax Obligations for Remote Employees

The good news: Federal tax obligations remain consistent regardless of where your employees are located within the U.S.:

• Federal Income Tax Withholding: Based on the employee's Form W-4 and applicable withholding tables
• Social Security and Medicare (FICA): 6.2% for Social Security (up to the annual wage base limit) and 1.45% for Medicare, matched by you as the employer
• Federal Unemployment Tax (FUTA): Paid only by employers, typically 0.6% on the first $7,000 of each employee's annual wages (after state unemployment tax credits)

Where remote work gets complicated is at the state and local levels.

State and Local Tax Obligations: The Remote Work Challenge

Each remote worker potentially connects your business to a new tax jurisdiction. Here's what you need to consider:

1. State Registration Requirements

Before you can properly withhold taxes, you need to register with each state where your remote employees work. This typically involves:

• Registering with the state's Department of Revenue for income tax withholding
• Registering with the Department of Labor (or equivalent) for unemployment insurance
• Obtaining state tax ID numbers and unemployment account numbers
• Setting up accounts for filing returns and remitting taxes

📌 Pro tip: Some states offer combined registration portals. Check each state's website for specific requirements and registration thresholds.

2. State Income Tax Withholding

You must withhold state income tax based on where the employee physically performs their work (with some important exceptions):

• States without income tax: Alaska, Florida, Nevada, New Hampshire (as of 2025), South Dakota, Tennessee (as of 2025), Texas, Washington, and Wyoming
• States with "convenience of employer" rules: Arkansas, Connecticut, Delaware, Nebraska, New York, and Pennsylvania may require withholding for the employer's state even if the employee works remotely elsewhere

3. State Unemployment Insurance (SUI)

Perhaps the most frequently mishandled aspect of remote work taxation:

• SUI is generally paid to the state where the employee physically works
• Each state has different tax rates and wage bases
• Paying to the wrong state can result in double taxation scenarios
• Correcting SUI errors often requires communication between state agencies

📊 Key Statistic: According to data from Symmetry Payroll, SUI taxes can vary dramatically between states. For example, in California, the maximum UI tax rate is 6.2%, making the highest possible tax per employee $434 (6.2% of $7,000) per year.

4. Local Income Taxes

Beyond state taxes, some cities and counties impose their own income taxes, such as:

• New York City and Yonkers in New York State
• Many municipalities in Ohio, Pennsylvania, and other states

Understanding Nexus: When a Remote Employee Triggers Business Tax Obligations

"Nexus" refers to a sufficient connection between your business and a state that allows the state to tax your business. A single remote employee can create nexus, potentially triggering:

• State income tax filing requirements for your business
• Sales tax collection and remittance obligations
• Other business taxes depending on state law

The 2006 Telebright Corp decision established that even one telecommuting employee can create nexus for a business. This principle has been reinforced by subsequent court decisions and state regulations.

What this means for you: Every time you hire a remote employee in a new state, you should conduct a nexus analysis to understand your new business tax obligations.

The Cost of Remote Work Tax Errors

Payroll mistakes can be expensive. According to recent research, US employees are 26% more likely to experience a payroll error than their UK counterparts, with a quarter of workers in America having encountered a payroll issue in the last three months. This may be due to the greater frequency of paychecks and the notoriously complex US tax system.

Neglecting to pay SUTA or SUI taxes correctly can result in:

• Penalties and interest averaging $4,200 per employee
• Time-consuming audits requiring 16+ hours of administrative work per error
• Damage to your company's reputationEmployee dissatisfaction and turnover

For perspective on SUI tax rates, in 2024-2025:

• SUI tax rates vary widely between states
• Some states use specific formulas based on employer history
• New employer rates typically range from 1-3.4% depending on the state
• Wage bases (the amount of each employee's wages subject to the tax) range from as low as $7,000 in some states to nearly $50,000 in others

• Invest in payroll software specifically designed to handle multi-state workforces

Many businesses find value in partnering with specialized payroll providers who handle tax filings and compliance with employment laws across multiple states, reducing your administrative burden and compliance risk.
