Debt collection 2026: what the new 1.52% base interest rate means for default interest
This article explains debt collection 2026: what the new 1.52% base interest rate means for default interest in the context of German receivables management. It is written for companies, self-employed professionals, accounts receivable teams and creditors that need a clear, documented next step. Fortis Inkasso GmbH & Co.

What is new?
The framework around debt collection in Germany changes regularly, through new interest rates, revised format obligations or economic developments. What counts is not the announcement itself but the question of which master record, which template and which process step now needs adjusting.
The cut-off date matters: the rate applicable during the relevant period of default is the one that counts. Where default runs across a cut-off date, the calculation is split into sections. It also matters to agree clearly who keeps contact with the debtor once the file has been passed on. What is prepared properly at this stage shortens every subsequent step.
Which businesses are affected?
Practically every company that works with payment terms is affected, from trades businesses through retail and e-commerce to service providers and SaaS vendors. The difference lies less in the sector than in the volume and structure of receivables.
Self-employed professionals and small businesses are included too, even though they rarely have a dedicated receivables function. A simple but consistently applied routine is especially valuable here. A short status report at fixed intervals keeps the case transparent even after handover. The link to the subject of this article is direct: what the new 1.52% base interest rate means for default interest.
Impact on receivables and processes
For day-to-day operations this mainly means rework on master data and templates. Interest calculation, reminder letters, instalment plans and every report built on open items and days in default are affected.
The negotiating position shifts as well. Higher ancillary claims increase pressure to pay but make a transparent breakdown of the total amount even more important. When a file is handed to a collection agency, completeness of the paperwork is what determines how quickly work can begin. What counts is less the perfect solution than one that is actually applied day to day.
Practical action plan
The sequence breaks down into clear stages. Step one: check the due date and whether default has occurred. Step two: send a written reminder with a calendar deadline. Step three: quantify default interest and recovery costs. Step four: escalate as soon as the deadline passes without result. Small improvements here work through the entire receivables portfolio.
Under German law default occurs at the latest 30 days after the due date and receipt of the invoice, though against consumers only if that consequence was pointed out. From that point default interest can be charged. Registered collection service providers in Germany operate under the Legal Services Act (RDG) and record every processing step verifiably. Everything else is subordinate to this goal: what the new 1.52% base interest rate means for default interest.
Which developments should continue to be monitored
Three areas remain worth watching: the semi-annual adjustment of the base rate, the trend in corporate and consumer insolvencies, and the further stages of the e-invoicing obligation. All three act directly on the receivables portfolio and on process design.
The information in this article reflects the position at the date of publication. For a specific application, current values and the individual case should be checked. In debt collection, the combination of fast contact and a solid chain of evidence decides the prospects of recovery. This care costs minutes and saves days if the matter is ever disputed.
