Client Stories

Trusted by individuals and businesses nationwide

“I’m on an H-1B and tax season used to genuinely stress me out — FICA, state taxes, all of it. One Stop Tax Filers sorted my return in a couple of days and even found a Social Security refund I had no idea I was owed.”
Rohan MehtaSoftware Engineer · San Jose, CA
“My husband needed an ITIN and my first W-7 came back rejected when I tried it myself. They spotted the document problem in ten minutes, refiled it, and it went through clean. I should have just called them first.”
Ananya IyerMarketing Manager · Hyderabad, India
“Nine employees and I was still running payroll off a spreadsheet. One Stop Tax Filers took over payroll, deposits, and the year-end W-2s. Honestly I haven’t thought about payroll since.”
Michael TurnerOwner, Turner HVAC · Columbus, OH
“Nine employees and I was still running payroll off a spreadsheet. Missed a deposit once and the penalty stung. They handle all of it now — deposits, quarterlies, the W-2s at year end — and I genuinely haven't thought about payroll since.”
Portrait of Ray Coleman
Ray ColemanOwner, Coleman HVAC · Columbus, OH
“First full year freelancing and I had no clue what I could deduct or how much to set aside. They walked me through quarterlies, fixed the W-4 at my part-time job, and my refund came back bigger than my last two years put together.”

Questions

Frequently asked

If you earned US-source income — wages, rent, interest or capital gains — you generally need to file Form 1040-NR. We also check whether the India–US tax treaty (DTAA) can lower what you owe.

If the combined balance of your foreign bank accounts went over $10,000 at any time during the year, you must file FinCEN Form 114 (FBAR). It is due April 15, with an automatic extension to October 15.

For individuals: photo ID, last year’s return, and income forms like W-2s or 1099s, plus records of deductions and credits. Businesses add profit-and-loss statements, expense records and payroll data. We send a personal checklist after your consultation.

Pricing depends on how complex your situation is. You always get an upfront, flat quote after a free review — before any work begins.
