"At first I was a little sceptical, but afterwards I was very happy that I chose this company. The tax consultants were very competent and friendly. Within a very short time, the tax return was completed without last year's tax return. In the second year I sent the tax documents by post and only had to pick up the completed tax return. "Michael B.

The Base-Stadt tax administration sends out tax returns every year around mid-January to private individuals in Basel so that they can be sent back to the tax administration on time. By 31.03. they should have the tax return completed and send it to the tax administration! If you do not have time to search the documents together and submit the tax return by the deadline, then you can apply for an extension. The first extension until 30.09 is free of charge and can be applied for with the extension card or a short letter to the tax administration. If you need a further extension until 31.12., you must pay a fee of CHF 40 and state a good reason for granting the extension. Those who do not submit their tax return at all will be assessed by the tax authorities and will receive a fine of CHF 100 to 500. If you need assistance in submitting an extension, we will be happy to help you.
