Tax Deduction Finder

When to Use This Skill

• User is preparing for tax season and wants to maximize deductions
• User is a freelancer or solopreneur unsure what they can deduct
• User wants a checklist of commonly missed deductions for their industry
• User needs to know documentation requirements for specific deductions
• User recently started a business and does not know what qualifies as a business expense

Core Principle

EVERY LEGITIMATE DEDUCTION MISSED IS MONEY LEFT ON THE TABLE — BUT EVERY UNSUPPORTED DEDUCTION IS AN AUDIT RISK. DOCUMENT EVERYTHING.

Tax Disclaimer

IMPORTANT: This skill provides general educational information about common business deductions. It does not constitute tax advice. Tax laws vary by jurisdiction, change frequently, and depend on individual circumstances. Always consult a qualified CPA or tax professional before claiming deductions. The information here is based on general US federal tax principles and may not apply to your specific situation.

2. Identify the industry/niche (freelancer, e-commerce, consultant, content creator, etc.)
3. Ask if the user works from home (home office deduction eligibility)
4. Ask if the user uses a personal vehicle for business

Phase 2: Generate Deduction Checklist

5. Present the universal deduction checklist (applies to most businesses):

Recovery and Fallback

• If the user does not know their entity type, assume sole proprietor (Schedule C) unless they mention incorporating — this covers the majority of solopreneurs
• If the user is unsure whether something qualifies as a deduction, apply the "ordinary and necessary" test: Is it common in your industry? Is it helpful for your business? If both yes, it is likely deductible — but recommend confirming with a CPA
• If the user has no receipt for an expense, they can use bank or credit card statements as backup documentation — but original receipts are stronger
• If the user has not been tracking deductions all year, help them reconstruct from bank statements by categorizing the last 12 months of transactions

Constraints

• Always include the tax disclaimer — this is educational, not tax advice
• Do not calculate exact tax liability — provide estimates as ranges and recommend a CPA for exact numbers
• Do not advise on audit defense strategies — that requires legal expertise
• Do not recommend aggressive or questionable deductions (100% personal vehicle as business, luxury items without clear business purpose)
• IRS mileage rates change annually — note that the user should verify the current rate
• Do not provide state-specific tax guidance — state deduction rules vary significantly
• Always recommend separating personal and business finances (dedicated business bank account)
• Retirement contribution limits change annually — recommend verifying current limits with the IRS or a CPA
