About the Book

Whether you’re a contractor, a firm that hires contractors or a recruitment agency, IR35 & Off-Payroll Explained gives you the expert knowledge to stay compliant, reduce tax risk, and successfully defend against any HMRC investigation.

IR35 has traditionally meant a costly compliance burden for contractors, and significant tax hits for those unfortunate enough to fall within its poorly defined boundaries. Since April 2021, private sector firms and recruiters bear the brunt of the Off-Payroll legislation, which shifts the compliance burden and tax liabilities onto them.

The threat to the contracting supply chain has never been greater, but with this book, you’ll have all you need to navigate this cumbersome legislation.
