Sole trader, GmbH, or partnership?
Trade law does not prescribe a legal form — but it does draw one line. Under § 9 (1) GewO, legal entities and registered partnerships (GmbH, OG, KG) may hold a trade licence, but they „must have appointed a managing director (§ 39)“ — a named person who carries the qualification and the legal responsibility for the trade. As a sole trader you are that person yourself.
Whether a GmbH pays off financially depends on profit, drawings, SVS contributions and allowances. There is no general profit threshold, and that question belongs to a tax adviser, not to this page.
Running this trade alongside a job
Nothing in Austrian law forbids running a trade as a side business. Two things about social insurance are regularly misremembered, and both cost money.
- The obligation follows Chamber membership, not profit. Under § 2 (1) 1 GSVG compulsory SVS insurance attaches to membership of the Economic Chamber, which you acquire with the trade licence itself. It therefore applies in a year in which you make no profit at all.
- There is an exemption — but only on application. § 4 (1) 7 GSVG lets very small businesses be exempted while turnover and income stay under the limits it refers to. Nothing happens automatically: without the application, the obligation stands.
If you are employed, check your employment contract separately for a secondary-activity clause — that is a matter between you and your employer, not trade law.
