Remote Work & Multi-State Taxes: A Self-Employed Guide 2026
Understand which states tax your remote work income, how reciprocity agreements work, and strategies to avoid double taxation when working across state lines.
The Residency Rule
Your home state generally taxes all your income, regardless of where your clients are located. If you live in California and serve clients in New York, California taxes that income. The complication arises when you physically work in other states.
Working in Multiple States
If you physically work in a state (even temporarily), that state may tax income earned there. States without income tax (TX, FL, NV, WA, etc.) simplify this dramatically. For multi-state workers, you may owe tax in your home state AND each state where you worked — with a credit for taxes paid to other states.
Reciprocity Agreements
Some neighboring states have reciprocity: residents of one don't pay income tax to the other. Examples include the mid-Atlantic (PA/NJ/DE), Midwest (IL/WI/IN), and DMV area (MD/VA/DC) agreements. Remote workers in reciprocity states file only in their home state.
Practical Record-Keeping
Track days worked in each state meticulously — calendars, travel receipts, client invoices. Most states use a days-worked threshold (commonly 10-30 days) before requiring filing. Your home state gives a credit for taxes paid to other states, preventing true double taxation but adding complexity.

How these numbers are produced
Calculations follow the order of operations on the IRS forms themselves: net profit, the 92.35% adjustment, self-employment tax, the 50% deduction against AGI, the standard deduction, the §199A QBI deduction with its phase-out, then the federal brackets. State tax is computed separately on state AGI less that state's own standard deduction, because no state allows the federal QBI deduction and almost none allow the federal standard deduction.
What it does not cover. The calculators model a single filer or a married couple filing jointly with self-employment income as the main source. They do not model local income taxes, W-2 wages held alongside freelance work, itemized deductions, the alternative minimum tax, or credits. Where a local income tax exists, it is described on that state's page.
Not advice. SelfTaxCalc produces estimates, not tax advice. No one here is a CPA, an enrolled agent or a tax attorney, and nothing on this site creates a professional relationship. Estimates are a starting point for planning and for a conversation with a professional — they are not a substitute for one.
