This guide provides a structured approach for freelancers to conduct a post-tax audit of their financials. It outlines six key questions to analyze both business performance and financial health based on the previous year's tax return. The first section focuses on business metrics, encouraging users to identify revenue patterns, evaluate client contributions, and assess engagement profitability. The second section shifts to financial analysis, prompting users to categorize expenses, track client payment timelines, and identify areas for improvement. Additionally, the guide presents tax-planning strategies to implement before the end of the year, including quarterly estimates and retirement account contributions. A worked example illustrates these concepts using a fictional freelancer's data, showcasing how to apply the framework effectively. The workbook emphasizes the importance of proactive financial management to avoid surprises during tax season.
