Salary certificates (Lohnausweis) as a Swissdec ELM 5.0 DeclareSalary document with TaxSalaries — the input for Swissdec ViewGen >= 2026.05 (TaxAccountingReport / Barcode). Same payroll filters as the payroll table; the certificates cover the whole calendar year: the row filters of the payroll table (month, status, payment date) do not narrow them, only employeeId does; contactId = contact person of the organisation printed on the certificates; ahvNotificationDate=<staffId>:<yyyy-MM-dd>, repeated = the date the compensation office was notified of a negative AHV wage; untilMonth=1..11 = the declaration year-to-date as of the end of that month (Jahresmeldung rueckwirkend)
