We are pleased to announce that Jonathan Kalinski and Sebastian Voth will be speaking at the upcoming CalCPA webinar on Employment Tax Resolving Federal and State Employment Tax Matters – Worker Classification on Tuesday, August 18, 2026, 9:00 a.m. – 10:30 a.m. (PST).
The IRS is increasing enforcement against taxpayers who fail to comply with withholding and remitting of employment taxes. Noncompliance can cause heavy penalties and interest against taxpayers that could destabilize a company and its operations and expose responsible company officers to personal liability. Tax professionals and advisers must grasp a complete understanding of tax rules and available techniques to avoid or minimize tax assessments and penalties. This webinar will guide tax professionals and advisers on critical issues relating to employment taxes. The panel will discuss essential techniques to avoid penalties and handling IRS audits stemming from employment taxes. The panel will also address worker classification issues and methods to overcome them, the impact of California AB 5, key considerations for state versus federal compliance, the Government use of injunctions and criminal aspects.
