Tax Advisor for Your Side Business in Germany

When you actually need help, how to prepare for an initial consultation, and what you can clarify on your own beforehand.

What This Is About

Many side businesses start without a tax advisor. That can work if you are a sole trader (Einzelunternehmer) or freelancer (Freiberufler), have few receipts, use the small-business exemption (Kleinunternehmerregelung), and keep your income-surplus calculation (EÜR) clean on your own.

A tax advisor becomes valuable as soon as things are no longer straightforward: VAT obligations, large investments, employees, a UG or GmbH, multiple income streams, cross-border activity, platform revenues, or uncertainty around advance tax payments.

When an Initial Consultation Makes Sense

Before registering your business, if you are unsure whether your activity qualifies as a trade (Gewerbe) or a freelance profession (Freiberuf), whether the small-business exemption fits your situation, or which legal structure makes sense.

After your first income comes in, if you notice that receipts, VAT, tools, and advance payments are becoming hard to keep track of.

Before forming a UG or GmbH, because accounting requirements, annual financial statements, and ongoing obligations are significantly more complex than for a sole trader.

How to Find the Right Tax Advisor

What matters is not just expertise but fit: digital communication, experience with side businesses, familiarity with tools such as DATEV, Lexware, or sevDesk, clear communication, and realistic pricing.

Ask directly: Does the firm take on small mandates? Do they work digitally? Do they support EÜR filings and clients using the small-business exemption? Are there flat fees or hourly billing? What software do they expect you to use?

If you only need orientation, a one-off initial consultation is often better than immediately signing up for an ongoing mandate. If you regularly deal with VAT, payroll, balance sheets, or annual financial statements, ongoing support is more realistic.

What Freya Can Help You Prepare

Freya can help you sort through your questions and put together a solid agenda for an initial consultation: your activity, legal structure, estimated revenue, type of clients, tool setup, volume of receipts, and open tax questions.

Freya does not replace tax advice. But she can help you go into a conversation prepared and recognize more quickly whether a firm is a good fit for your situation.

Tool, Tax Firm, or Both?

Accounting software is good for routine tasks: invoices, receipts, bank reconciliation, reports, and exports. A tax advisor is good for context, complex decisions, tax filings, annual statements, and professional certainty.

For a side business, a hybrid approach often makes the most sense: you keep your day-to-day records and receipts in order, and the firm handles the difficult questions or takes over the parts you do not want to be responsible for yourself.

Before choosing a tool, it is worth asking whether your future tax firm can work with it. Otherwise you save a few euros at the start and pay later with manual rework.

Good Preparation Saves Time

Before an initial consultation, write down your activity, legal structure, start date, estimated revenue, costs, client types, platforms, tools, and any open questions.

If you have already started, gather your invoices, receipts, bank statements, letters from the tax office (Finanzamt), and platform payout reports. The clearer the picture, the more concrete the advice can be.

Questions that may matter for your case

These questions help you classify the topic. In the start plan they are connected to your situation. You can also think through the answers beforehand.

  • Are you looking for a one-off initial consultation or ongoing support?
  • Are you a sole trader, freelancer, GbR (civil-law partnership), UG, or GmbH?
  • Are you using the small-business exemption (Kleinunternehmerregelung) or charging VAT?
  • How many receipts and invoices do you expect per month?
  • What software are you using or would you like to use?
