Best Practices

• Keep prompts specific to tax contexts like 1040 lines, schedules, credits, and deductions to reduce ambiguity.
• Embed data quality checks and validation steps so outputs are ready for filing or review.
• Reuse prompts with minor context tweaks for similar client profiles to maintain consistency.
• Protect sensitive data with redaction guidance and data handling notes before sharing.
• Test prompts with sample datasets and document any assumptions for transparency.

Common Mistakes to Avoid

• Using generic prompts that lack tax-specific mapping or form references.
• Overestimating model capabilities without providing validation steps.
• Neglecting data sensitivity and redaction when handling client information.
• Missing clear output formats, causing outputs to be hard to import or review.
• Failing to include edge cases like multi-state data, carryovers, or complex credits.
