Restricted Stock Units (RSUs) are a form of equity compensation often granted to employees. Determining the tax basis of these shares is critical for accurate tax reporting when they are eventually sold. The basis is generally the fair market value of the shares on the date they vest, less any amount the employee paid for them. For example, if an employee receives 100 RSUs that vest when the stock price is $50 per share, the cost basis would be $5,000 (100 shares x $50). This figure is used to calculate capital gains or losses upon a future sale.

Accurately establishing the cost basis of equity compensation offers significant financial advantages. It ensures that capital gains taxes are calculated correctly, potentially minimizing tax liabilities. Furthermore, precise record-keeping is vital for compliance with tax regulations, preventing potential penalties and audits.
