--- title: The Swissdec cockpit description: Track the salary declarations to be made, check and download them, mark them as declared outside Swissdec and set up the SUA certificate. url: "http://illizeo.com/en/centre-aide/swiss-payroll-swissdec-cockpit/" updated: "2026-11-11" category: Payroll / Swiss payroll --- # The Swissdec cockpit The salaries calculated by Swiss payroll are declared to compensation funds, insurers, pension institutions and cantonal tax authorities, following the Swissdec ELM standard. The **Swissdec cockpit** brings these declarations together: what is to be declared, what needs following up, and the history of what has been done. This article explains its tabs, how to produce and check a declaration, and how to mark it as declared outside Swissdec while electronic transmission is not yet open. It is intended for payroll managers and administrators. ## Before you start - The cockpit opens with one of the three Swissdec rights: **Swissdec cockpit and transmissions**, **SUA company certificate** or **Subscriptions to institutions**. At **Access** level it can be read; marking a declaration, ordering a certificate or subscribing to an institution require **Execute** level. - Everyone only sees the tasks of their Swissdec rights (declarations, SUA certificate, subscriptions, pension contributions, withholding tax corrections). - Declarations are created from closed payrolls — see [Calculating and closing monthly payrolls](https://illizeo.com/en/centre-aide/swiss-payroll-monthly-payroll-runs/). Annual declarations carry every salary of the scope: if you cannot see them all, the screen says so. ## Swissdec v6: declaring outside Swissdec in the meantime Swissdec version 6 is not yet open for certification. Electronic transmission therefore stays disabled, and the cockpit shows **Waiting for Swissdec v6**: “Swissdec transmission will be activated as soon as Swissdec version 6 is open for certification. Until then, declarations are checked, downloaded and declared outside Swissdec.” In practice, for each declaration: you check it, download its file, submit it to the institution (portal, e-mail, post…), then mark it as declared outside Swissdec. The cockpit task closes. ## The cockpit tabs Open **Swiss payroll › Swissdec cockpit**. The **All employers** filter narrows the display to one employer. ![Swissdec cockpit, Overview tab: the Employer list set to All employers, the Swissdec v6 banner, the Overview, Annual, Monthly, History, OPA contributions, Withholding tax corrections and Configuration tabs, the Tasks card with “No open task”, then the Monthly declarations, Annual declarations and Salary certificates cards.](https://i0.wp.com/illizeo.com/wp-content/uploads/2026/11/paie-suisse-17.en_-scaled.png?resize=800%2C304&quality=80&ssl=1) The cockpit: what is to be declared and what needs following up. - **Overview**: the open **Tasks**, first what needs following up (failure, refusal, maintenance), then what is to be declared, each with an **Open** link; below, the **Declarations** card summarises the monthly declarations, the annual declarations and the salary certificates. When everything is done: “No open task”. - **Monthly**: the monthly declarations of each closed payroll — withholding tax and FSO statistics, to the tax authorities of the cantons. - **Annual**: the year’s annual declarations — compensation fund, family allowances, accident, daily allowance and pension insurance, cross-border workers — and the salary certificates to the cantonal tax authorities. - **History**: every declaration made, with its receipts and notifications, filterable by year and by nature. - **Configuration**: each employer’s SUA company certificate and the subscriptions to institutions. Depending on your rights, **OPA contributions** and **Withholding tax corrections** tabs are added. ## Preparing and checking a declaration 1. In the **Monthly** or **Annual** tab, choose the declaration to make. 2. The **ELM 6.0 declaration** panel counts what it carries (people, certificates, withholding tax declarations, FSO lines, events, cross-border workers) and checks the file against the official ELM 6.0 schemas. If it is valid, the screen shows “Valid against the official ELM 6.0 schemas.”. 3. If it is not, click **Show the schema errors** to read the errors; the **Data to complete** list names what is missing. Complete it, then come back. 4. Click **Download the XML** to get the declaration file. A declaration can also be blocked by an employer setting, for example a French cross-border worker whose telework exceeds 40 % when the employer has chosen to block: the screen says so and shows where to change the setting. ## Marking a declaration as made outside Swissdec 1. Submit the file to the institution. 2. Click **Mark as declared outside Swissdec**. 3. Enter the **Date of the declaration**, the **Means of declaration** (**Institution’s portal**, **E-mail**, **Post** or **Other**) and, if you wish, a **Comment (optional)**. 4. Confirm. The message “Declaration marked as made outside Swissdec.” appears and the task closes. The declaration shows the date, the means and your name. If it was a mistake, **Remove** withdraws the mark. If your workspace requires four-eyes validation, the mark is sent for validation: “Mark sent for validation: it is set when a second manager approves it.” The changes of the month (entries, exits, OASI, family allowance and pension changes) are marked in the same way, from the **Changes of the month** section of each closed payroll. ## Swissdec configuration ### The SUA company certificate The SUA certificate signs changes and subscriptions to institutions. Each employer needs one. In the **Configuration** tab, **Company certificate (SUA)** card: 1. Click **Order the SUA certificate**. At least one accident, daily allowance or pension contract is needed to prove the company’s identity. 2. A password arrives by post. Enter it, then click **Activate**. 3. The certificate becomes **Active**. It then renews itself. ### Subscriptions to institutions The **Subscriptions to institutions** card shows, for each of the employer’s accident, daily allowance or pension contracts, whether it is **Subscribed** or **Not subscribed**. The subscription tells the insurer or pension institution that the company can be reached via Swissdec. Click **Subscribe**, then **Send the subscription**; **Synchronise** collects the institution’s messages, and **Unsubscribe** ends the subscription. An active SUA certificate is required to subscribe. ## Good to know - The cockpit recalculates nothing: each declaration comes from a closed payroll or from the annual outputs. - As long as Swissdec v6 is not open, nothing is sent electronically from Illizeo: you submit each file to the institution yourself. - A failed SFTP deposit is retried twice, then reported in the cockpit. ## Frequently asked questions ### The Transmit button is disabled. That is expected: transmission stays disabled while waiting for Swissdec v6. Download the file, submit it to the institution and mark the declaration as declared outside Swissdec. ### The cockpit is empty. No payroll is closed, or no sub-company is calculated by Illizeo. Declarations are created when a payroll is closed. ### I cannot see the Configuration tab. It requires the **SUA company certificate** or **Subscriptions to institutions** right. ### *Similaire*
