Do sole proprietors need a business license?

Yes, the same ones any other business form would need. Sole proprietorship is the default legal status of one person doing business without forming an entity; it is not an exemption category. Cities that require business registration require it of sole proprietors, states that license an activity license the person directly, and skipping formation paperwork does not skip licensing paperwork.

What is genuinely simpler

A sole proprietor skips entity formation, annual reports, and registered agent obligations, and applies for licenses as an individual, which shortens some applications. A DBA filing is often the only formation-adjacent step, needed when operating under a name other than your own. Hobby-scale activity sometimes falls under local minimums or exemptions, though the thresholds are local and worth confirming rather than assuming.

What is exactly the same

The licensing analysis does not care about your entity type. The questions remain what you do and where: local registration where you operate, home occupation permit if you work from home, seller's permit if you sell taxable goods, professional or activity licenses if your field is regulated. One difference cuts against the sole proprietor: licenses are issued to you personally, so compliance history follows you, and moving to an LLC later means updating or refiling licenses in the new entity's name.
