Clinical Trial Participant - Tax Certification Process

Welcome to the tax certification process. We're delighted to have you here as part of our process to ensure seamless payments. In the United States, clinical trial payments are considered reportable income by the Internal Revenue Service (IRS) and a tax form is required for accurate tax reporting.

To get started, please select the ‘CLINCARD’ button to the right and follow the prompts to provide the requested tax identity information. If you have any questions or need assistance at any point, our dedicated support team is here to assist you.

Thank you for your cooperation. Your contribution is vital to the success of our endeavours, and we're grateful for your involvement in our programs.
