LLC is your legal entity. Amazon is asking for your taxing entity (i.e. C-Corp, S-Corp, Partnership). I’d recommend going back to whoever set up your LLC and asking under what tax structure you’ve been set up as.
if youre just an individual using your social security number (could also have an EIN) that would be sole proprietership. For my situation, my accountant advised against it, but that might work great for some people.
An LLC is an entity created by state statute. Depending on elections made by the LLC and the number of members, the IRS will treat an LLC either as a corporation, partnership, or as part of the owner’s tax return (a “disregarded entity”). Specifically,a domestic LLC with at least two members is classified as a partnership for federal income tax purposes unless it files Form 8832 and affirmatively elects to be treated as a corporation. And an LLC with only one member is treated as an entity disregarded as separate from its owner for income tax purposes (but as a separate entity for purposes of employment tax and certain excise taxes), unless it files Form 8832 and affirmatively elects to be treated as a corporation.
Owner of Single-Member LLC
If a single-member LLC does not elect to be treated as a corporation, the LLC is a “disregarded entity,” and the LLC’s activities should be reflected on its owner’s federal tax return. If the owner is an individual, the activities of the LLC will generally be reflected on:
Form 1040 Schedule C, Profit or Loss from Business (Sole Proprietorship) (PDF)
Form 1040 Schedule E, Supplemental Income or Loss (PDF)
Form 1040 Schedule F, Profit or Loss from Farming (PDF)
An individual owner of a single-member LLC that operates a trade or business is subject to the tax on net earnings from self employment in the same manner as a sole proprietorship.
If the single-member LLC is owned by a corporation or partnership, the LLC should be reflected on its owner’s federal tax return as a division of the corporation or partnership.
