Smartsteuer relies on a pure browser approach: no installation, no download – just open it in your browser and get started. The unique selling point is the assessment check with an integrated objection generator, which automatically checks whether the Finanzamt (tax office) has calculated correctly.

Highlights of our Smartsteuer review

  • Smartsteuer scores 74/100 points – the best online-only solution.
  • Assessment check and objection generator as a unique selling point.
  • Prepare for free, €39.99 per filing.
  • Fully browser-based – no installation needed.

1 Range of functions

21/35
Points
Smartsteuer supports income tax with all common forms (N, KAP, V, R) as well as trade tax in outline. There is no document retrieval with pre-filling – data has to be entered manually. The tax tips are at a basic level. Direct ELSTER submission (the tax authorities' online filing system) and especially the assessment check with objection generator are strong. Scoring (21/35): Solid range of functions with the strong assessment check. Deduction for the missing automatic document retrieval and only basic tips.

2 Usability

16/21
Points
The interview mode is well structured and guides logically through the tax return. The help texts are solid, but without video explanations. Carry-over from the previous year is possible via import. Scoring (16/21): Good user guidance, but not quite as intuitive as Taxfix. Help at text level without videos.

3 Price & licence

13/21
Points
Prepare for free, €39.99 on submission. One tax return per purchase. Fair-use principle as with most online providers. Scoring (13/21): Free trial version top. Price in the midfield, only 1 return per purchase.

Points
Email support and FAQ. No telephone support, no tax adviser hotline. Hosting in Germany, GDPR-compliant. Scoring (5/11): Email support only, without a tax adviser. Good data protection.
