Our verdict on WISO Grundsteuer

WISO Grundsteuer is a browser-based product for preparing German property tax declarations. It is aimed at real estate owners who need to report property and ownership details, rather than taxpayers looking for a general income-tax return tool. The workflow guides users through declaration preparation, automatically fills some information, and supports digital submission to the tax office. Access is online on computers and tablets, without a software download.

According to the vendor’s pricing page, the WISO Grundsteuer license costs €29.95 one time and covers declarations for up to three property units. The license can be expanded to cover up to 99 units, which may suit owners with several properties. The vendor’s product page does not show the price for expanding coverage, so buyers should check that cost before choosing it for a larger portfolio. There is no free plan described in the published offer.

Its defining strength is a narrow scope: declaration guidance, partial automatic completion, and digital submission are all centered on German property tax. That focus makes it a sensible fit for property owners who want a dedicated route through this filing task, and the browser-based format avoids installing software. It is not the right choice for someone who wants to prepare a general income-tax return in the same product; WISO Grundsteuer is sold separately from WISO Steuer. Buyers needing broader tax preparation should choose a product that covers those returns, while property owners seeking this specific declaration workflow can consider WISO Grundsteuer.
