TAXLITIGATOR – Tax Controversy (Civil & Criminal) Report

We are pleased to announce that Dennis Perez, Michel R. Stein, and Robert S. Horwitz will be speaking at the upcoming Strafford webinar on Federal and State Tax Residency Rules: Latest IRS Examination Guidance, and Navigating State Tax Regulations, and Remote Workers on Monday, July 20, 2026, 10:00 a.m. – 11:50 a.m. (PST).

This webinar will guide tax professionals and advisers on the latest IRS residency examination guidance and California residency issues. The panel will discuss federal and state tax residency rules, California residency issues, income allocation issues in the residency context, managing residency audits, and best practices for advising clients who are considering leaving California. California state tax residency rules, and an increase in residency audits and enforcement, require tax professionals to know state residency and income allocation issues, so they can properly advise their clients when these issues arise.

This CLE/CPE webinar will provide tax professionals guidance on key planning considerations for taxpayers. The panel will discuss the importance of both citizenship and residence in determining tax liabilities of individuals, challenges for remote workers, allocating income between jurisdictions, dual residency issues, principal items targeted by regulatory authorities, and other key items.
