What smartsteuer is
smartsteuer is an online tax-return service for people filing in Germany, including employees, self-employed people, retirees and students. Its guided interview asks relevant questions step by step, while smartCheck reviews a return for errors, plausibility problems and possible tax-saving opportunities. VaSt can retrieve tax data from the tax office for a pre-filled return, and users can transfer data from prior years. An interface sends EÜR data from Lexware Office bookkeeping to smartsteuer, and completed returns are submitted electronically to the tax office using ELSTER. The service supports amended returns and rental income, but does not cover special cases such as profit determination for agriculture and forestry. It runs in a browser on desktop, tablet or smartphone without installation; listed platforms also include Android, iOS, Linux, macOS and Windows. The paid plan is €39.99 per year, billed by tax year, and a free trial is available. smartsteuer says it encrypts data, stores it in German data centres and cites PCI DSS and SAS 70 Type IIb standards.
