File contents

Help the user find missed tax deductions by analyzing their transactions:

Step 1: Gather data

Call search_transactions for the specified period (default: current year)
Call get_company_details to understand the business type
Call list_tax_settings to check VAT status and tax regime

Step 2: Scan for common deductions

Review each transaction and flag potential deductions that may be miscategorized or unverified. Look for these common German freelancer/small business deductions:

Home office (Arbeitszimmer):

Rent, electricity, internet, heating proportional to office space
Office furniture, equipment, monitors, desks

Technology & software:

SaaS subscriptions (Adobe, Google Workspace, Slack, hosting)
Computer hardware (fully deductible if under 1000 EUR net, otherwise depreciated)
Phone and mobile plans (business portion)

Travel & transportation (Reisekosten):

Public transport, fuel, car maintenance
Hotels for business trips
Meals during business travel (Verpflegungspauschale: 14 EUR/28 EUR per day)

Professional development:

Courses, certifications, books, conferences
Professional memberships and associations

Insurance & financial:

Professional liability insurance (Berufshaftpflicht)
Business bank account fees
Tax advisor fees (Steuerberater)

Marketing & client acquisition:

Advertising, domain names, hosting
Business cards, printed materials
Client gifts (up to 35 EUR per person per year)

Step 3: Suggest corrections

For each potentially missed deduction:

Show the transaction: date, amount, description, current category
Suggest the correct SKR04 category
Explain why it qualifies as a deduction
Use categorize_transaction to recategorize if the user confirms

Step 4: Estimate impact

Present a summary:

Number of transactions reviewed
Number of potential missed deductions found
Estimated additional deductible amount (EUR)
Approximate tax savings (rough estimate using ~30-42% marginal rate for Einkommensteuer + Soli)

Tips:

Items under 1000 EUR net (GWG - Geringwertige Wirtschaftsgüter) can be fully deducted in the purchase year
Items over 1000 EUR must be depreciated over their useful life (AfA)
Mixed-use items (e.g., phone) should only claim the business portion
Keep receipts for all deductions - suggest attaching any missing ones
