What problem does it solve? Israeli self-employed professionals and small companies routinely misapply expense deduction rules, such as treating client meals as 80% deductible or applying a flat 45% to vehicle costs, producing incorrect tax reports for their accountants. ## Core Features & Use Cases - Accurate deduction rules: Applies the correct Israeli Tax Ordinance mechanics, including the vehicle higher-of rule (running costs minus use-value vs 45%), the mobile phone 1,380 ILS-or-50% disallowance floor, 0% deduction for hosting Israeli clients, and proportional home office splits. - Entity-aware VAT handling: Distinguishes Osek Patur, Osek Murshe, and company structures for VAT eligibility, including the private-car purchase VAT ban (regulation 14) and the 2/3 vs 1/4 running-cost VAT split (regulation 18). - Chart of accounts mapping and reporting: Maps each expense to a common Israeli chart-of-accounts code, flags missing documentation and dual-use items, and outputs a summary report or enriched CSV. - Use Case: A freelance developer pastes a month of expenses (cloud hosting, fuel, phone bill, client coffee) and receives a categorized report with deductible amounts, account codes, VAT notes, and flags for items needing receipts. ## Quick Start Ask the assistant to categorize your list of business expenses for Israeli tax reporting, stating whether you are an Osek Patur or Osek Murshe.
