Delaware LLCs offer flexibility in tax treatment. By default, your Prompt Engineer LLC will be taxed as a pass-through entity, meaning profits are passed through to your personal income and taxed at your individual rate. You can elect to be taxed as an S-Corp or C-Corp for potentially different tax implications. For a deeper dive, see our resource on [how to register an LLC in Delaware](https://www.lovie.co/formation/resources/llc-formation/agency-delaware). Delaware does not tax profits earned outside of the state, which is a huge benefit to prompt engineers selling prompts and services nationwide. Lovie can help you determine the most advantageous tax structure for your specific situation and automate ongoing compliance.
