FFD 1.05, 1.1, and 1.2: What's the Difference and Do You Need to Upgrade?

FFD (Format of Fiscal Documents) is the "language" used by a POS terminal to communicate with the OFD and the tax authority: a set of tags and rules into which every receipt is packaged. The FFD version determines what data a receipt can contain in general — in particular, whether the POS terminal can sell marked goods. We break down the differences between versions, how to check yours, and what is required to switch to the current one.

1. What is FFD and Why It Is Not "Just Firmware"#

FFD stands for Fiscal Document Format, approved by the FTS (Federal Tax Service): it describes the composition and structure of receipt tags (amount, VAT rate, calculation attribute, product details, etc.), rather than the cash register software itself. Cash register firmware must support the required FFD version, and the version itself is recorded during cash register registration or re-registration with the tax authority — it cannot be changed arbitrarily without formal documentation.

2. Version Comparison Table#

A detailed breakdown of how error correction in 1.05 differs from 1.1/1.2 can be found in the guide to correction receipts.

3. How to find out your cash register version#

The FFD version can be checked without opening the cash register hardware in one of the following ways:

• in the cash register registration or reregistration report — the version is specified directly in the document;
• in your OFD personal account — in the cash register profile among the technical parameters;
• in your FTS personal account ("Cash Register Accounting") — in the same section as the register's registration data;
• in the cash register settings or in the morning shift open report — most models print the FFD version in the service data.

4. Who is required to switch to FFD 1.2, and who can stay on 1.05#

Required to switch to 1.2 — all sellers of marked goods (footwear, clothing, certain light industry product categories, items included in the Chestny ZNAK system as the list expands). Without 1.2, the POS cannot physically generate a request and receive a response for a marking code — which means it cannot legally sell such an item.

Can stay on 1.05 — if there are no marked goods in the product range and none are planned, and there are no other reasons for a mandatory transition. The presence of "non-core" product categories on 1.05 is not a violation in itself.

5. What you need to switch to FFD 1.2#

1. Cash register firmware supporting 1.2. Not all older models receive it — check with the manufacturer or in the CRE register whether an update is available specifically for your model.
2. FN-M fiscal drive. It can work with track-and-trace marking tags, whereas a standard FN cannot.
   • If an FN-M is already installed — no need to replace the FN, proceed directly to re-registration.
   • If an old FN without "M" support is installed — as a general rule, it can be used until its expiration date, as long as you are not required to apply 1.2. As soon as the obligation to sell marked goods arises, the FN must be replaced with an FN-M in advance, without waiting for its natural expiration.
3. CRE re-registration in the FTS online account, specifying the reason for re-registration — switching to another FFD version. If the FN was not replaced — re-registration takes place without replacing the FN; if replaced — it is processed as a standard FN replacement simultaneously with switching to 1.2.

6. Mandatory Item Names on Receipts#

Since 2021, the requirement to specify the name of the product, work, or service on the receipt applies to all sellers, including special tax regimes (simplified tax system, patent), for which it was previously optional. Printing generic terms like "Product" or "Service" on a receipt without a specific name is not allowed — the wording must reflect the actual item name.

Practical consequence: the item name on the receipt must be linked to the product card in the inventory system or catalog — if a cashier enters the name manually "by eye," discrepancies will eventually accumulate between what was actually sold and what is printed on the receipt.

7. Settlement Method Indicator#

The settlement method indicator tag shows the payment stage of the transaction. Main values and when to apply each:

An error in this attribute is a common reason for correction; a breakdown of a specific case involving advance payments and prepayment offsets can be found in the article "Errors with advance payments and prepayment offsets".

8. Digital receipt instead of paper#

To send a customer an electronic receipt (email, phone number), their contact information must be obtained before payment — requesting a phone number or email after the fact, once the receipt has already been issued, cannot be retroactively processed as a "digital receipt instead of paper". If there is no contact information, but the customer does not need a paper receipt or it was lost, a copy can be found via the FTS service "My Online Receipts" using purchase details — without contacting the seller.

9. VAT 22% from 2026 — What to Reconfigure#

Starting January 1, 2026, the main VAT rate in Russia is 22% (the reduced rate of 10% remains, and special rates of 5% and 7% apply to STS taxpayers who exceeded the threshold). Before issuing any receipts or corrections, check:

• VAT rates in the cash register settings — the firmware must support the up-to-date values;
• rates in the inventory management system/catalog — at the level of categories and individual items, including reduced-rate items (10%) and special STS rates;
• transitional receipts at the turn of periods (December 2025 → January 2026) — which rate should apply depends on the date of actual payment, not the date of shipment; for analysis of VAT rate errors and how to correct them, see the article "Correction receipt for incorrect VAT rate".

10. Example#

A shoe store operated on FFD 1.05 and did not sell marked goods. Starting from the date of the mandatory transition of the "footwear" category to mandatory marking, the store must switch to 1.2: it receives firmware supporting 1.2 from the cash register manufacturer, replaces the old FN (without "M") with an FN-M in advance — before the obligation takes effect, rather than at the last minute — and submits a re-registration application in the FNS personal account specifying the reason "switch to another FFD version". After the application is processed, the cash register continues operating without interruption, but now with support for requesting and verifying marking codes.

11. How to do this in Cenaly#

• VAT rates are configured at the item and category level in the Cenaly menu/item catalog — update them before starting sales under the new 2026 rates.
• Item names on the receipt are generated automatically from catalog cards — manual entry "by eye" on the POS side is not required if the product range is entered into the system.
• The labeling flag is enabled in the item card — the POS prompts to scan the code upon sale; for details, see the article "Labeling on the POS".
• Fiscalization on a physical register with the required FFD version goes through Cenaly Hardware Bridge; corrections of erroneous receipts are handled via the "Correction Receipt" panel in the Equipment section.

12. Frequently Asked Questions#

I have a cash register on 1.05, no labeled goods — is it mandatory to switch to 1.2? No, the obligation to switch is tied to the sale of labeled goods, not to the date itself. As long as the product range does not include such goods, remaining on 1.05 is legal.

Can I update the firmware to 1.2, but keep the old FN without "M"? No, working in 1.2 with full labeling verification requires specifically an FN-M — a standard FN physically does not support the required tags, even if the cash register firmware is updated.

Do I need to notify the FTS with a separate letter when switching to 1.2? Yes, in the form of an application for CRE re-registration via the FTS personal account specifying the reason — this is the official notification, no separate letter is required.

The VAT rate changed, but we forgot to update the cash register firmware — the receipt went through with the old rate. What to do? This is an error on the receipt, not a choice of FFD version — it is fixed with a correction receipt (on 1.1/1.2) or a pair of return and sale receipts (on 1.05). A detailed algorithm is in the article on VAT rate error.
