Whether investments are the main activity of your company or a side venture, taxation works the same way. Unlike individuals, you don't receive control information for your investments from the borrower; instead, you're obligated to report them yourself. Below, you can see where in the tax return your returns should be reported:

When you lend money to borrowers through SaveLends' savings platform, your investment generates returns in the form of interest, on which the tax rate is 22%. To accurately report this to the Swedish Tax Agency (Skatteverket), you report the total received interest as interest income in box 3.15.

As a business owner, you have the right to deduct taxes in the declaration for credit losses:

If, as a corporation, you have invested in another company that is not in the same group of interests (does not constitute part of the same group), the capital loss should be declared in box 3.18 (interest expenses and similar income items). The loss will affect your tax-related result and thus entail a tax reduction of 22 percent of the amount (current corporate tax).
