The 2026 Czech winery reporting map
The three recurring wine declarations below go to the Vineyard Register maintained by the Central Institute for Supervising and Testing in Agriculture, ÚKZÚZ. The State Agricultural and Food Inspection Authority, SZPI, has separate notification and food-control responsibilities.
| Report | Snapshot / period | 2026 cycle deadline | Who is in scope | Official channel |
|---|---|---|---|---|
| Harvest declaration | Results at December 31 | January 15, 2027 | Grape producers unless the whole crop qualifies for the processing exemption; grape merchants also file | Vineyard Register / Farmer Portal or accepted ÚKZÚZ submission route |
| Production declaration | Results at December 31 | January 15, 2027 | Wine producers, subject to the narrow cooperative-member exemption in the official guidance | Vineyard Register / Farmer Portal or accepted ÚKZÚZ submission route |
| Stock declaration | Stocks held July 31, 2026 | September 10, 2026 | Producers, processors, bottlers and merchants holding stocks, subject to broker and qualifying-retailer exemptions | Vineyard Register / Farmer Portal or paper submission to ÚKZÚZ |
Official basis: ÚKZÚZ, Vineyard registration and 2026 declaration deadlines; SZPI, Wine guidance.
Who must file Czech wine declarations?
Czech and EU wine rules use distinct operator roles. A business can occupy more than one role, so start by mapping what you actually do: grow grapes, buy or sell grapes, produce wine, process wine products, bottle, hold stock, act as a merchant, broker or retailer.
Harvest declaration
A grape producer files the harvest declaration unless the entire grape crop is processed, or caused to be processed, into wine under the Czech-law exemption. A grape merchant is also required to file harvest-related information. This is why a vineyard-size shortcut can produce the wrong answer.
Production declaration
Wine producers established in the Czech Republic file a production declaration by January 15. Current SZPI guidance says the declaration is required even when production is zero. A specific exemption exists for members of cooperative wineries that deliver their full grape crop while retaining an entitlement to less than 1,000 litres for their own consumption.
Stock declaration
Producers, processors, bottlers and merchants holding wine-sector stocks on July 31 are generally in scope. Brokers who never hold stock are exempt. Retailers can also be exempt when they meet the official small-retailer conditions, including annual sales of no more than 750 hl of packaged wine plus no more than 1,000 litres of cask wine and the other conditions stated in the official guidance. If a retailer fails any required condition, do not assume the exemption applies.
Verify role definitions and exemptions in SZPI's current Wine guidance and § 29 of Act No. 321/2004 Coll..
Before you file: registration and access
- Confirm your Vineyard Register data. Vineyard and operator records need to match the entity and activity behind the declaration.
- Confirm your operator notifications. A producer must notify ÚKZÚZ of the start, interruption or end of wine production no later than the day the event occurs.
- Set up Farmer Portal access if filing online. The Ministry's authenticated RVI web services use Farmer Portal credentials and a separate web-services key.
- Reconcile your source records first. Declaration totals should be traceable to vineyard, cellar, purchase, production, bottling and stock records rather than reconstructed at the deadline.
Legal basis for production-status notification: § 11 of Act No. 321/2004 Coll.. Online service details: MZe web-service catalogue.
The three annual declarations, step by step
1. Harvest declaration
- Confirm whether your grape-producer or grape-merchant activity is in scope.
- Reconcile vineyard parcels, grape varieties, quantities harvested and any grape movements against your source records.
- Use the December 31 reporting position required by Czech law.
- Submit by January 15 of the following year. For the 2026 harvest, the published deadline is January 15, 2027.
2. Production declaration
- Reconcile own-harvest and purchased raw materials with the wine actually produced.
- Include the required production figures as of December 31, even when reportable production is zero unless a valid exemption applies.
- Resolve discrepancies before submission so the production declaration agrees with cellar and stock records.
- Submit by January 15 of the following year. For 2026 production, the published deadline is January 15, 2027.
3. Stock declaration
- Take the required July 31 stock position.
- Reconcile bulk and packaged wine balances, including wine held for or received from other operators where relevant to your records.
- Confirm whether a broker or retailer exemption actually applies before omitting the filing.
- Submit the July 31, 2026 position by September 10, 2026.
What winery records must support the declarations?
Current SZPI guidance requires evidential records for producers, processors, grape producers, importers, merchants, brokers and bottlers. Electronic records are allowed, but they must protect the integrity of the history. SZPI specifically warns that ordinary Excel or Word files do not satisfy the electronic-record requirement when entries can simply be changed or deleted without the required controls.
| Record event | Entry timing in current guidance | Operational implication |
|---|---|---|
| Product received | By the next working day | Capture receipt, lot, source and quantity at intake |
| Product dispatched | By the third working day | Keep movements linked to invoices / dispatch evidence |
| Oenological treatment | By the next working day | Post treatments to the affected lot promptly |
| Materials used for enrichment or acidification-related operations | Same day | Do not confuse this record-entry timing with the separate authority-notification deadline |
Source: SZPI, Wine guidance, section on evidential books and entry timing.
Cellar events that can trigger separate SZPI notifications
Annual declarations are not the whole compliance calendar. Certain oenological operations have their own notice requirements.
| Event | Current verified rule | Authority |
|---|---|---|
| Enrichment | Notify the competent SZPI inspectorate at least 48 hours before the intended operation. | SZPI |
| Acidification / deacidification | Written notification is required under the applicable rules. This guide does not assign an unsupported same-day notice deadline. | SZPI |
| Sweetening | Notify before the operation. | SZPI |
| Pomace wine for own consumption | Notify SZPI at least seven days before production. | SZPI |

How to file through the Vineyard Register
ÚKZÚZ's current declaration page directs electronic filers to the Farmer Portal / Vineyard Register and also describes paper submission for the stock declaration. Ministry guidance also supports submissions through the official RVI web services from local software.
- Open your Vineyard Register access. Confirm the correct operator and reporting year before entering data.
- Select the declaration type. Harvest, production and stock are distinct filings with distinct scope rules.
- Populate from reconciled records. Avoid building the declaration from memory or from an editable summary spreadsheet with no audit trail.
- Review totals and cross-check balances. Compare production, movements and stocks for internal consistency.
- Submit and retain evidence. Keep the confirmation or official response with the supporting records used to prepare the declaration.
Current deadlines and channel: ÚKZÚZ. Ministry helpdesk for electronic exchange: +420 222 312 977, helpdesk@mze.gov.cz.
Can Czech winery software submit the declarations by API?
Yes, technically. The Czech Ministry of Agriculture publishes RVI web services specifically allowing local software to submit all three annual declarations. The current catalogue exposes production and test definitions, including XSD/WSDL resources, for these services:
| Declaration | Current service ID | Authentication | Verified purpose |
|---|---|---|---|
| Harvest | RVI_PSK01B | PF / Farmer Portal web-services key | Submit harvest declaration from local software |
| Stock | RVI_PZA01B | PF / Farmer Portal web-services key | Submit stock declaration from local software |
| Production | RVI_PPR01B | PF / Farmer Portal web-services key | Submit production declaration from local software |
The PF authentication flow is based on the Farmer Portal username and a separate web-services key. The Ministry documents the SOAP-message hashing flow and also provides the vOKOsender utility for automated submission of prepared XML. Implementers should consume the current WSDL/XSD and authentication documentation from the Ministry rather than hard-code examples copied from an old integration note.
Primary technical sources: MZe service catalogue, MZe authentication/hash procedure, and MZe vOKOsender.
Corrections, evidence and enforcement
If a filed declaration is wrong, correct it through the applicable official channel and keep the reconciliation that explains the change. Do not overwrite the source history that produced the original figures. Czech wine law treats failures involving required declarations, evidential records and certain oenological notifications as administrative offences, with the sanction depending on the specific breach.
Enforcement framework: § 39 of Act No. 321/2004 Coll.. For a specific correction route or penalty exposure, confirm with the responsible authority or Czech counsel rather than relying on a generic penalty number.
Common mistakes to avoid
- Using vineyard area alone to decide whether a harvest declaration is required.
- Skipping a production declaration because production was zero without checking the official exemption.
- Assuming every retailer is exempt from the July 31 stock declaration.
- Treating a normal editable spreadsheet as a compliant electronic evidential book.
- Confusing same-day record entry with a same-day authority-notification deadline.
- Waiting until January to reconcile crop, production and cellar-movement data.
- Implementing only production and stock APIs while omitting the harvest service
RVI_PSK01B.
What about the Wine Fund, VAT, excise tax and packaging reports?
These are separate from the Vineyard Register and are conditional on the business's legal form, VAT/excise status, packaging activity and contractual compliance route. They should not be presented as additional universal winery filings.
| Area | Verified 2026 point | Why the old shortcut fails |
|---|---|---|
| Vinařský fond | A levy and accompanying statement apply to a grower with at least 1 ha of registered vineyards or a producer that reported at least 1,000 litres of wine. The statement is sent with the applicable levy payment. | This obligation uses its own thresholds and payment schedule. It is not the same filing as the ÚKZÚZ production declaration. |
| VAT control statement | A VAT-paying legal entity files the control statement monthly, within 25 days after month-end. An individual follows the VAT-return period. | Quarterly VAT eligibility does not make a legal entity's control statement quarterly. The VAT-period turnover threshold is now CZK 15 million, subject to the other statutory conditions. |
| Corporate income tax | The general filing framework is three months after the tax period, four months for the statutory electronic route when not filed in the first three months, and six months in the audit/adviser cases described by the Financial Administration. | Fixed March 31 / June 30 dates are stale and can be wrong from year to year. |
| Wine excise | Czech still wine currently has a zero excise rate, but registration, movement or return obligations can still arise depending on the operator and activity. Sparkling wine and intermediate products are treated differently. | Do not assume every winery owes a monthly cash excise payment, or that a zero rate removes every excise obligation. |
| EKO-KOM | EKO-KOM clients submit quarterly packaging statements; the 2026 client deadlines are April 30, July 30, October 30 and January 30 following Q4. | An EKO-KOM quarterly statement is not a universal quarterly report for every winery. |

How Solera can support Czech winery reporting
The hardest part of a declaration is usually not the final form. It is having defensible source data before the deadline. Solera's verified product scope covers vineyard operations, lab data, cellar work, additions, production, inventory and audit-oriented records. That makes it possible to keep the operational facts that feed a compliance workflow in one connected system instead of reconstructing them in January.
What this guide does not claim: the current Solera product materials supplied for this review do not verify a live, production Czech RVI or SZPI direct-submission integration. The Czech government interfaces exist and are documented above, but Solera should not be described as filing RVI_PSK01B, RVI_PZA01B or RVI_PPR01B directly until that product capability is implemented and tested.
Frequently asked questions
When is the Czech stock declaration due in 2026?
The stock declaration reports stocks held on July 31, 2026 and is due September 10, 2026, according to ÚKZÚZ's current Vineyard Register page.
When are the 2026 harvest and production declarations due?
Both use the position at December 31, 2026 and are due January 15, 2027.
Does every Czech grape grower file a harvest declaration?
No. Current Czech guidance provides an exemption where the grape producer's entire crop is processed, or caused to be processed, into wine. Do not substitute a 1,000 m² vineyard-area rule for the actual scope test.
Do I file a production declaration if I produced zero wine?
Current SZPI guidance says the production declaration is filed even when production is zero, unless a valid exemption applies.
Can I keep the required wine records in Excel?
Not as an ordinary editable spreadsheet. SZPI says electronic evidential records must prevent impermissible alteration or deletion; normal Excel or Word files without the required controls do not meet that standard.
Is there an official Czech API for wine declarations?
Yes. MZe currently lists RVI_PSK01B for harvest, RVI_PZA01B for stock and RVI_PPR01B for production submissions from local software, with Farmer Portal web-service authentication.
Does Solera submit these Czech declarations directly?
Not as a verified live capability in the product materials reviewed for this guide. Solera can support the operational recordkeeping behind the workflow, while direct Czech government submission should only be claimed after the integration is implemented and tested.
