Why Taxes Get Complicated for Remote Workers

Working from anywhere has obvious perks—no commute, flexible hours, and sometimes a lower cost of living. Yet remote arrangements can also create thorny tax issues. U.S. states have varying rules about where income should be taxed when work spans multiple locations. Some states require you to pay income tax where the work is physically performed, even if your company is elsewhere. Others base taxation on your place of residence. If you log on from a different state even a few days a year, you may technically owe taxes there too.

Determining the correct portion of income subject to each state’s tax often perplexes remote employees. For example, living in New Jersey but occasionally commuting to a New York office might mean part of your salary is taxable in New York. Without careful tracking, you could end up overpaying or underpaying taxes, leading to penalties or lost refunds. Keeping good records of where you work each day is key.

How This Calculator Works

The goal of this tool is to offer a simplified estimate of your state tax liability when you split workdays between two locations. You input your annual salary and the number of days you worked in your home state versus another state. You also provide the income tax rate for each state, expressed as a percentage. The calculator then allocates your salary based on days worked in each location and multiplies by the respective tax rate. The result shows an estimated tax due to each state as well as the combined total.

The formula is conceptually straightforward. First the tool assumes 260 working days per year (about five days per week). It calculates the daily income rate by dividing your salary by 260. Then it multiplies that daily rate by the number of days you worked in each state. Finally, it applies the appropriate tax rate to that portion of income. Keep in mind this is a simplified approach and does not account for deductions, credits, or special reciprocity agreements between states.

Example Table: Comparing Two States

State	Tax Rate	Days Worked	Taxable Income	Estimated Tax
Home (NJ)	5%	200	$76,923	$3,846
Other (NY)	6%	60	$23,077	$1,385
Total		260	$100,000	$5,231

In this hypothetical example, the remote worker spent 60 days in New York, so roughly 23% of their salary was taxed at New York’s higher rate. The remainder was taxed in their home state. Your own situation may involve a very different split of days or different tax rates. The calculator helps you see how much you might owe each jurisdiction.

Practical Advice for Multi-State Filers

If you routinely work in more than one state, consider keeping a detailed log of where you perform services each day. Some employers provide this tracking, but if not, a simple spreadsheet or smartphone app works well. When tax season rolls around, you’ll have clear documentation to support your state allocations.

Be aware that certain states have “convenience of the employer” rules that can override where you physically worked. For instance, if your company is based in New York and your remote work is considered for your own convenience rather than your employer’s necessity, New York may tax all your income even if you live elsewhere. Research your state’s specific policies or consult a tax professional if you’re unsure.

Limitations and Next Steps

This calculator is a starting point for gauging your potential tax burden. It does not capture every possible deduction or credit. Nor does it handle local taxes or complicated rules around nonresident filings. Use the results as a ballpark figure and seek personalized advice to optimize your filings. As remote work arrangements evolve, so too will state tax enforcement. Staying informed ensures you remain compliant while avoiding unpleasant surprises.

To help track multiple work locations, you can now click Add Another State and include a second set of days and tax rates. The calculator will show a table summarizing the taxable income and tax for each state. Once you have your totals, hit Copy Result to save the final tax figure for your records or to share with your accountant.

Ultimately, understanding where you owe taxes helps you budget more effectively. By adjusting withholdings or setting aside money throughout the year, you can better prepare for any additional tax due. The convenience of remote work doesn’t have to come with tax-time headaches, especially when you plan ahead.
