Professional U.S. Tax & Non-Resident Identification Support

We provide professional document preparation and advisory support for non-resident U.S. tax compliance, tax filings, and FIRPTA refund claims. All services are subject to a private service fee for independent, third-party assistance only, and we are not affiliated with the IRS.

Nolly (U.S. Tax Recovery Inc.) is an independent document preparation and tax support service. We are not affiliated with, endorsed by, or acting on behalf of the IRS or any government agency. Individual Taxpayer Identification Numbers and Employer Identification Numbers are issued solely by the Internal Revenue Service (IRS).
