Federal vs. State Income Tax: Essential Insights for International Companies Hiring in the US
For international businesses managing employees across multiple US states, understanding the nuances of federal and state income tax is crucial. While both tax types fund essential government services, they operate on separate systems with distinct rules, rates, and deductions. Navigating these differences effectively can help you ensure compliance, optimize payroll management, and avoid costly errors.
In this guide, we’ll break down the main distinctions between federal and state income tax, how they impact employers with international teams in the US, and why understanding these tax systems is essential for managing payroll across state lines.

1. Federal Income Tax: The National Standard
The federal income tax is administered by the Internal Revenue Service (IRS) and applies to all income earned by individuals and businesses nationwide. Federal tax rates are progressive, meaning they increase as income rises, ranging from 10% to 37%. For international companies employing US-based remote workers, understanding federal tax requirements is essential for accurate payroll calculations and compliance.
Key aspects of federal income tax for employers:
- Progressive tax rates: Higher-income employees pay a higher percentage in federal taxes.
- Mandatory contributions: Employers must withhold federal income tax from employees' paychecks, based on their W-4 forms.
- Funding: Federal taxes fund national programs like defense, social security, and infrastructure.
Note: International businesses must adhere to federal payroll tax regulations to avoid penalties. Managing these requirements can be simplified with a global payroll platform like Ontop. Book a demo to streamline compliance.
2. State Income Tax: A Complex Patchwork
Unlike the federal tax system, state income tax varies significantly across the 50 states. Some states, like Texas and Florida, impose no income tax, while others, like California, have progressive tax systems that can go up to 13.3% for high earners. For employers, this variability presents additional complexities in managing payroll, as you need to adapt to each state’s tax rates, deductions, and filing requirements.
Key aspects of state income tax for employers:
- Varied tax rates: States may have no income tax, a flat tax rate, or a progressive tax system.
- Different deadlines: While federal tax returns are due on April 15, state deadlines vary.
- Unique deductions and credits: Each state has its own set of deductions and credits, which can affect taxable income differently than at the federal level.
For companies hiring remote employees across different states, adapting to each jurisdiction's tax requirements is essential. Ontop offers solutions to automate payroll and ensure compliance with varying state tax regulations. Book a demo to see how we can help.
3. Implications for International Companies with US-Based Employees
For international businesses hiring across the US, understanding federal and state tax requirements isn’t just about compliance—it’s essential for strategic payroll planning and employee satisfaction. Failing to accurately withhold and remit state taxes, for example, can lead to penalties, impact employee net pay, and even create legal risks.
Considerations for international employers:
- Multi-state payroll complexity: Each state has its own tax regulations, creating additional administrative work for payroll teams.
- Employee morale: Ensuring accurate tax withholdings helps maintain trust and satisfaction among employees.
- Compliance risk: Missteps in tax withholdings or filings can result in audits, penalties, or reputational harm.
