FAQs
Frequently asked questions
Can an Indian accounting firm prepare US tax returns?
Yes. Offshore teams commonly prepare US individual and business returns as support for US CPA and EA firms. The US firm's signing preparer reviews, signs and e-files the return, and the taxpayer's consent under IRS Section 7216 is obtained before return information is disclosed to the offshore preparer.
Which US tax forms do you prepare?
Form 1040 with common schedules and state returns, Form 1065 partnership returns, Form 1120 and 1120-S corporate returns with K-1s, and year-end 1099s. Tell us your mix and we will confirm fit during the scoping call.
How does the time difference work for US firms?
India is 9.5 to 13.5 hours ahead of mainland US time zones, so files you send in the evening are usually worked on overnight and back the next morning. We also keep a daily overlap window for calls.
Do you work in QuickBooks Online and Xero?
Yes. We work directly in your QuickBooks Online, QuickBooks Desktop (via remote access) or Xero files, together with tools such as Gusto, ADP, Bill.com and Dext.
Can you help during tax season only?
Yes. Many firms use us for January–April and September–October overflow, then keep a smaller monthly bookkeeping engagement for the rest of the year.
