As a Prompt Engineer LLC in DC, your tax structure will depend on whether you elect to be taxed as a pass-through entity (sole proprietorship or partnership) or as a corporation (S-Corp or C-Corp). Most LLCs start as pass-through entities. Pass-through entities mean that the business itself doesn't pay income taxes; instead, the profits 'pass through' to the owner(s) who then report them on their personal income tax returns. In DC, this also triggers the Unincorporated Business Franchise Tax. This connects to our resource on [setting up your Alaska LLC](https://www.lovie.co/formation/resources/llc-formation/accounting-alaska), which covers the details. Electing to be taxed as an S-Corp or C-Corp can change how you pay self-employment taxes and may offer different deduction opportunities. Consult with a tax professional to determine the optimal structure for your prompt engineering business.
