Details worth checking

Ensure Personal Information Accuracy

Accurate personal information is crucial for tax processing. Incorrect names or SSNs/ITINs can delay processing or lead to penalties. Ensure all personal data is accurate and matches your documents.

Complete and Correct Address Entry

Incomplete or incorrect addresses can delay communications and refunds from tax authorities. Make sure all address fields, including foreign addresses, are properly filled.

Verify Date of Birth Information

Incorrect or incomplete birth dates can affect tax credits and processing. Ensure both taxpayer and spouse/RDP birth dates are correct and formatted properly.

Select the Correct Filing Status

Choosing the wrong filing status can result in incorrect tax calculations, leading to overpayments or underpayments. Ensure your status matches your actual situation.

Claim the Right Number of Exemptions

Incorrect exemption claims can affect tax liability. Ensure you claim the correct number based on personal, senior, and dependent criteria.

Avoid Incorrect Income Reporting

Misreporting income from California sources can lead to tax miscalculations and penalties. Accurately report all types of income, including wages and rents.
