1. Overview of the one-click tax filing launch
Starting March 31, 2026, registration opens for the first user groups for a new one-click tax filing feature in the official tax app. The service will go live on July 1, 2026 and initially targets roughly 11.5 million taxpayers: mainly single, childless employees and retirees without additional income such as rental income. The system delivers a prefilled tax return for the 2025 tax year, built from automated payroll, pension and insurance data, and offers a preview of the tax assessment before a simple one-click submission.
The aim is to shift from manually filling out forms to a mostly passive confirmation process: users review a ready-made return on their smartphone, make any edits if needed, and then approve the filing with one click. Authorities emphasize a nationwide, uniform rollout to avoid regionally different solutions and announce a step-by-step expansion to include more taxpayer groups over time.
2. How the one-click filing works
The one-click tax filing feature creates a prefilled tax return using official data sources. Automated inputs include payroll information, pension and insurance data for the relevant tax year. Once those records are assembled, the app generates a draft return and a preview of the expected tax assessment, giving users the chance to check or update details before final submission.
Data sources and privacy
Data used to prefill returns comes from employers’ payroll records, pension providers and insurance records for the tax year 2025. Officials describe the process as automated, aiming to reduce manual data entry. While the feature simplifies filing, some reports compare the user experience to online shopping and ask whether there are hidden catches. So far, no substantial opposing advice has been published, but transparency about data handling and the option to edit entries are highlighted as key safeguards.
Step-by-step user flow
- Create and verify an official tax account if you do not already have one.
- Download the tax authority’s official app and complete the in-app registration once it opens on March 31, 2026.
- After July 1, receive a prefilled tax return for tax year 2025 in the app if you are in the eligible group.
- Review the prefilled return and the preview of the tax assessment, edit any incorrect or missing items.
- Approve and submit the return with a single click; the final tax assessment follows through the usual official channel.
3. Registration, timeline and requirements
Key dates and requirements are straightforward: registration for early access begins on March 31, 2026; the one-click filing service starts on July 1, 2026. The feature uses 2025 tax year data. To use the service you need a verified official tax account and the official tax app installed on your smartphone. Authorities plan a phased expansion to include additional taxpayer groups after the initial launch.

4. Benefits, political reactions and common concerns
Officials from several states have welcomed the change as a major simplification. For example, a state finance minister explained that from July registered users will get a finished tax return directly on their smartphone and will only need one click to submit it. Another emphasized that tax filing used to mean paper piles and stress, and that this should now be a thing of the past. A third compared the process to online banking or shopping as a familiar, fast experience, while others called the move an important step in digitalisation.
Expected benefits include a large reduction in paperwork, faster and simpler filing for straightforward cases, and fewer errors from manual entry. The preview of the tax assessment is intended to give confidence before submission. However, some commentators raise cautious questions about whether the process is truly as effortless as it sounds and whether users fully understand the data and defaults used. Authorities underline that editing remains possible before submission and that the rollout will be monitored and expanded gradually.
