What problem does it solve? Russian small business owners face tax deadlines that arrive without invoices — missing one triggers penalties, account freezes, and surprise bills. This Skill proactively builds a personal tax calendar from 3-5 simple facts about the business, computes approximate payment amounts with code (not mental math), and warns early about approaching VAT and simplified-tax thresholds. ## Core Features & Use Cases - Proactive deadline surfacing: Starts with what is due in the next 30-60 days, with estimated amounts and formulas, rather than waiting for a question. - Deterministic tax calculation: The tax_calc.py script computes fixed self-employed contributions, the 1% extra contribution with yearly caps, simplified-tax (USN) advances with deduction rules, and VAT/USN threshold flags using constants from a verified 2026 registry (tax_data.py). - Threshold early warnings: Alerts before crossing the 20M RUB VAT threshold, the 490.5M RUB USN limit, or the 2.4M RUB self-employed (NPD) cap. - Use Case: An individual entrepreneur on USN 6% with ~8M RUB annual revenue asks nothing — the Skill reports the July 1 extra 1% contribution of ~77,000 RUB, the upcoming quarterly advance, and remaining headroom to the VAT threshold. ## Quick Start Ask the assistant to build your tax calendar by telling it your business form, tax regime, approximate revenue, and whether you have employees.
