As a Delaware LLC, your API business generally enjoys pass-through taxation. This means the profits and losses of the business are passed through to your personal income tax return. You'll need to pay self-employment taxes (Social Security and Medicare) on your share of the profits. Our resource on [LLC registration in Delaware](https://www.lovie.co/formation/resources/llc-formation/agency-delaware) breaks this down further. Delaware also has a franchise tax, even for LLCs, which must be paid annually.
