About this skill
What it does
The Schedule C Deduction Finder is a high-speed diagnostic tool for self-employed individuals, freelancers, and gig workers. It uses a structured 5-question interview to identify commonly overlooked tax deductions for 2025 filings. By analyzing user responses against IRC requirements, it surfaces specific opportunities involving home offices, vehicle use, health insurance, retirement contributions, and startup costs.
Why use this skill
Prompting a generic AI for tax help often leads to vague advice or outdated limits. This skill is hard-coded with 2025 deduction limits, specific IRS form lines, and mandatory IRC citations. It doesn't just list deductions; it provides an estimated "value on the table" range and a checklist of substantiation records required to survive an audit. It's designed to be the "pre-flight check" that ensures a developer or contractor doesn't overpay before they start their actual filing process.
Key Features
- 2025 Compliance: Uses current year rates and limits (e.g., standard mileage rates).
- Audit Readiness: Lists exact records needed for each flagged deduction.
- Form Accuracy: Directs users to the specific Schedule C or Schedule 1 lines.
- Gap Analysis: Quantifies the potential tax savings gap based on user-provided scenarios.
The output is a structured 3-deduction summary report, complete with a diagnostic disclaimer and a clear path for those needing full return preparation.
