You can switch anytime during the year.

If you start with the tax service within the year of 2021, all monthly fees of €99 each are due retrospectively for the previous months of 2021. For example, if you start with the tax service in June 2021, you will pay six times €99 for January 2021 to June 2021 and from July 2021 regularly €149 (or in the small business plan €99) per month plus VAT.
