Sweden's Financial Supervisory Authority (Finansinspektionen) has set the reporting timetable and technical requirements for payment service providers that offer euro payment transactions or direct debits under the EU Instant Payments Regulation, requiring them to submit fee and rejection data via its Fidac system. Reporting in Fidac becomes available on 26 February, and the first submission is due by 9 April 2026. In-scope providers must report fee levels for credit transfers, instant payments and payment accounts, and the share of transactions rejected due to the application of targeted financial restrictive measures, split between domestic and cross-border payment transactions. Data must be filed in XBRL-CSV, with some fields reported in EUR and others in national currency; the total number of payment accounts is measured as at 31 December, and account-fee data must also include fees for accounts closed during the reporting period. The reporting obligation in Fidac is driven by firms’ authorisations, so some providers that do not offer euro payment transactions or direct debits may still receive reminders, which they can disregard. For the first cycle, providers must report calendar-year data covering 26 October 2022 to 31 December 2025, using 31 December as the reference date; thereafter, reports are due by 9 April each year for the preceding calendar year. The templates and instructions follow the European Commission’s implementing regulation setting technical implementing standards for uniform reporting.
