What problem does it solve? Russian small business owners on USN or NPD face tax deadlines with unclear numbers: how much to set aside for quarterly advance payments, which self-employed contractors are missing "Moy nalog" receipts, and whether VAT obligations apply. This Skill gathers the data in advance and packages it into a structured document an accountant can work with directly, without long back-and-forth. ## Core Features & Use Cases - USN Advance Payment Calculation: Computes quarterly advance tax on a cumulative basis for both "Income" (6%) and "Income minus Expenses" (15%) objects, including the 1% minimum tax check, insurance contribution offsets, and payment deadlines (28.04 / 28.07 / 28.10). - Contractor Payment Accounting: Pulls payments to GPH contractors and self-employed workers from accounting systems and bank statements, splits them by tax status (self-employed / IP / individual), and flags missing "Moy nalog" receipts, contracts, and acts. - IP Insurance Contributions: Calculates fixed contributions (57,390 ₽ for 2026) plus the 1% on income above 300,000 ₽ with caps and deadlines. - VAT Warning (from 2026): Alerts when annual income exceeds 20 million ₽, triggering automatic VAT payer status, and collects data for the accountant's rate decision. - Use Case: An IP designer asks "how much do I pay as USN advance this quarter?" The Skill pulls year-to-date income, subtracts paid contributions and prior advances, and outputs a calculation with explicit assumptions for accountant review. ## Quick Start Ask the assistant to calculate your USN advance payment for this quarter or to reconcile all contractor payments for the year, and it will gather the data and produce an accountant-ready package.
