Fill in the online tax form for sole traders within one month of starting your business.
Choose the questionnaire for your actual legal form and activity, and prepare the information it requests about you and the business. Check ELSTER (the German online tax portal) account access before you need to submit. If management is outside Aachen or your case involves special tax rules, confirm responsibility rather than choosing an office by proximity. Ask the office about any case-specific evidence and deadlines; no fixed processing or tax-number issue date is promised here. If you have not yet been issued a personal tax ID or a tax number, ELSTER offers an email-only certificate-account route for completing and submitting the tax-registration questionnaire. It does not initially provide other forms or full account functions; enable those later when the required tax identifier is available.
