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 breaks this down further. Delaware also has a franchise tax, even for LLCs, which must be paid annually.
