Staying organized throughout the year is one of the best ways to reduce stress and avoid surprises during tax season. Whether you’re filing as an individual, self-employed professional, or business owner, gathering the right documents ahead of time can help streamline the process and uncover potential tax savings.

✅ 1099 forms (freelance, contractor, interest, dividends, retirement distributions)

✅ Social Security or disability income statements

✅ Records of rental or other passive income

✅ Bank and investment statements showing interest or dividends

Tax Credits & Deductions

✅ Child Tax Credit (CTC) information
