Tax software is not just about a feature list. The tax year, device, backups and purchase model must also fit your workflow. This researched purchasing checklist is not a hands-on test or individual tax advice. It concerns the German tax offering; translating this article does not make the software suitable for another country’s taxes.
One-off purchase or recurring contract?
Buhl offers WISO Steuer as a one-off purchase and a subscription. Check which option is selected at checkout. The subscription renews automatically each year. Confirm the current total price, renewal and cancellation in the contract terms; an attractive starting price alone is not enough. Buhl: WISO Steuer · Buhl: Abo
Five questions before setup
- Have you selected the correct tax year, and does the specific version cover the cases you need?
- Does the operating system or browser meet the vendor’s current requirements? Check the device you will actually use.
- How will existing data be imported? Keep an unchanged backup and verify imported entries.
- Who may access the account and documents? Use a maintained personal computer and appropriate access restrictions.
- How will you archive the completed return, supporting documents and submission confirmations? Plan a traceable export and backup process.
