 FNS Issued Clarifications on Simplified Taxation System — Accountant Studies for 2 Days, AI Analyzes in 30 Seconds On April 28, the Federal Tax Service (FNS) issued letter No. EA-36-3/3447@ with clarifications on how to correctly fill out notifications for transitioning to the Simplified Taxation System (STS) and changing the object of taxation. The reason is the adoption of Federal Law No. 104-FZ dated April 25, 2026, which changed the rules for the simplified system. What does this mean for small businesses? If you are on the STS or are planning to switch, the old notification forms no longer work. The new requirements took effect immediately. An error in filling out = refusal of transition or incorrect object of taxation. On average, an accountant spends 2 working days to understand the new clarifications: reading the letter, cross-referencing with the text of 104-FZ, understanding which fields have changed, and checking their reports. And that's if they are up to speed.
