Swissdec: what the standard requires and who needs it

The term appears in every data sheet and is explained in none. Yet it decides whether your payroll filings go out by themselves or by hand, every month.

The essentials

  1. Swissdec is the Swiss standard for electronic payroll data exchange. Over it the software reports salary data to the compensation fund, the accident insurer, the pension fund, the sickness daily allowance insurer and the cantonal tax administration — in one run instead of five.
  2. Whoever pays salaries has these reporting duties. Swissdec is not the duty but the route: without it the filings stay manual work, monthly and annually.
  3. 12 of the 15 payroll solutions compared serve the standard in full, 3 in a limited way. As of July 2026.
  4. «Payroll» in a feature list without Swissdec in practice almost always means: a payslip can be printed. That is the calculating part, not the filing part.

What Swissdec is and what it is not

Swissdec is an association and a standard, not an authority and not a product. The standard describes a uniform payroll data format and a procedure by which payroll software transmits the data to several recipients at once. What gets certified is the software, not the business.

What it is not: an obligation. The reporting duties themselves are in social insurance law and apply regardless of how you report. Swissdec is the route by which five filings become one operation — and the reason 12 of the 15 solutions compared serve it in full.

Five recipients, one run

That is the whole benefit of the standard: the same payroll data goes to five places without anyone entering it five times.

  1. Compensation fund

    AHV, IV, EO and unemployment insurance. The annual filing is the operation that shows in January whether the connection works.

  2. Accident insurer

    Wage sum reporting under the UVG, plus supplementary insurance. Distinguishing insured from uninsured wage types is done by the software or by a person.

  3. Pension fund

    BVG filings on joining and leaving, on salary changes and at year end. The area where filings are most often forgotten.

  4. Sickness daily allowance insurer

    Where one exists. The same wage sum, one more recipient.

  5. Cantonal tax administration

    Withholding tax accounting for staff without a settlement permit, with rates and deadlines that differ by canton.

What «limited» means

3 of the 15 solutions compared handle payroll in a limited way. In practice that almost always means: the payslip is produced, the salary certificate can be printed, and someone enters the filings by hand in the recipients’ portals.

For two employees that is bearable — a few forms in January. For twelve it is the reason payroll software gets bought: the effort grows with every salary recipient and every change, and every manual entry is a place where a figure diverges.

In practice one question tests it: does the annual run happen as one operation, or are there five outputs to upload? The answer is in no data sheet.

Between «calculates payroll» and «files payroll» lies all of the work.

Frequently asked questions

Do I need Swissdec with a single employee?

The filings are due regardless of how many employees there are. By hand it is bearable for one person. The standard pays off from the point where changes come regularly — joiners, leavers, salary changes.

Is Swissdec mandatory?

No. What is mandatory are the filings, not the route. Several recipients still accept filings through their portals; the standard replaces five entries with one.

How do I tell whether software serves the standard in full?

Swissdec keeps a list of certified solutions, and the version of the standard is part of it — certification against an older version does not cover newer filings. In the comparison, payroll capability appears as a row of its own with the three recorded levels: full, limited, absent.

Does this also apply to accounting software with a payroll module?

Yes, and there the distinction matters particularly: a payroll module inside an accounting solution often calculates without filing. The comparison of accounting solutions carries the same row.

The standard
Swissdec, the association for uniform payroll data exchange. The allocation of recipients follows the standard’s description; the reporting duties themselves follow from the AHVG, UVG and BVG.
