Key points at a glance
- The WTBG 2017 contains no advertising provision of its own. The benchmark is the UWG and professional law, above all § 1 WT-AARL and confidentiality under § 80 WTBG 2017.
- Professional titles are protected: anyone using “Wirtschaftsprüfer:in” without authorisation risks a fine of up to 20,000 € (§ 124 WTBG 2017).
- References and client logos only with consent; you should treat even the existence of an engagement as confidential.
- You may state fees. Commissions for referrals are prohibited, and for statutory audits the fee must not depend on additional services.
- Under § 174 TKG 2021, marketing emails and calls generally require prior consent, including towards businesses.
This post is general information, not legal or tax advice for your individual case. Laws, professional guidelines and chamber fees change: check the details with your chamber, the relevant authority or your professional association before you make a decision.
The legal framework: UWG plus professional law
Searching the consolidated text of the WTBG 2017 for “Werbung” (advertising) turns up nothing. The general guideline on practising the accountancy and tax professions (WT-AARL 2017-KSW) has no advertising section either. Your communication is therefore governed by two levels:
- Unfair competition law: the UWG prohibits misleading (§ 2), aggressive (§ 1a) and otherwise unfair commercial practices (§ 1) and regulates comparative advertising (§ 2a). This applies to audit firms just as to any business.
- Professional law: § 1 WT-AARL requires conscientious, careful, independent and confidential practice on your own responsibility. Breaching the practice guidelines is professional misconduct (§ 128 WTBG 2017), decided on by the KSW's disciplinary council.
In practice, this means: factual, verifiable information is allowed, even with a modern look. It becomes problematic when statements are untrue, cannot be proven, disparage colleagues or reveal confidential client information.
Title, firm name and APAB status
The professional title “Wirtschaftsprüfer” or “Wirtschaftsprüferin” is both mandatory and protected (§ 73 WTBG 2017). You may additionally use “Wirtschaftstreuhänder:in” and refer to other activities you are authorised to carry out, such as “Steuerberater:in” (tax adviser) or “eingetragene:r Mediator:in” (registered mediator). Using any of these titles without authorisation is an administrative offence with a fine of up to 20,000 € (§ 124 Abs. 1 WTBG 2017).

Three situations in which firms trip up here:
- Before recognition: a GmbH may only call itself “Wirtschaftsprüfungs GmbH” once the KSW has recognised it. You can prepare the domain and logo, but only publish afterwards.
- Trainees: the team profile says “Berufsanwärterin” (trainee) or “Prüfungsassistent” (audit assistant), not “auditor in training”, as long as the appointment is still pending.
- APAB certificate: “eingetragene Abschlussprüferin” (registered statutory auditor) is only correct while the time-limited certificate from the APAB (Austrian audit oversight authority) is valid. A statement such as “also for the audit of sustainability reports” requires that the certificate covers this scope.
Focus areas and specialisation
Austrian law for the accountancy professions has no protected specialist titles like the German “Fachanwalt”. You may therefore name focus areas, but you must be able to back them up. The benchmark is the ban on misleading statements: a focus area is one in which you demonstrably work on a regular basis.
How to get it right
- “Focus: audits of associations and non-profit organisations”, if this makes up a significant part of your engagements
- “We audit mid-sized GmbHs in industry and tourism”
- “Sworn and court-certified expert witness”, if you are entered in the list of court experts
- “Around 40 annual audits per season since 2019”, if you can prove it
Better avoid
- “Upper Austria's restructuring specialists” without a matching base of engagements
- “Austria's leading audit firm for family businesses”
- “Audit guaranteed without a qualified opinion”
- A list of services that names every authorisation under § 3 WTBG 2017 as a focus area
The last “don't” is not a prohibition but a common mistake: if everything is a focus area, you have none. For readers from management and supervisory boards, a short, honest list is more credible.
References, logos and client quotes
The duty of confidentiality under § 80 WTBG 2017 covers everything entrusted to you or learned in the course of your work. According to a widely held view, shared for example by the German Wirtschaftsprüferkammer (chamber of auditors), this includes the very fact that an engagement exists. Reference lists, client logos and quotes therefore require express consent, ideally in writing.
A special case in auditing: your name appears in the audit opinion, which is disclosed in the Firmenbuch (commercial register) together with the annual accounts. The fact that this information is publicly accessible does not automatically make it marketing material. We recommend obtaining consent here too before naming a client on your website.
How to keep references clean
- Obtain consent in text form, covering content, place (website, brochure, LinkedIn) and the option to withdraw
- Use anonymised case examples: “audit of a mechanical engineering GmbH with around 120 employees in Upper Austria”
- For quotes, give the role instead of the name if preferred: “Managing director, family business, Tyrol”
- Remove logos as soon as an engagement ends or consent is withdrawn
Google reviews and review portals
Reviews on Google or Herold are permitted for audit firms too, as long as they are genuine. Bought or self-written reviews are misleading within the meaning of the UWG. Google also prohibits incentives for reviews and approaching only satisfied clients; sharing a link or QR code is allowed. How to build your profile is explained in Google profile for professional firms.
Replying to a review is trickier. A reply usually confirms that an engagement exists or existed, and must contain no details. A neutral thank you or, in response to criticism, an offer to talk (“Please contact us directly so we can clear this up”) is the safe option. The review reply generator provides suggestions for such replies.
Fees and price information
There is no longer a binding fee scale; the chamber's former fee principles no longer apply. You may state prices or price ranges on your website, for example for audits of associations or an initial meeting. Under § 5 Abs. 2 ECG (E-Commerce Act), it must be clear whether VAT is included. Three rules set limits:
- Contingent fees only within limits (§ 8 WT-AARL).
- No commissions for referring engagements, neither paid nor accepted (§ 84 WTBG 2017). A “referral bonus” for clients falls under this.
- For statutory audits, the fee must be appropriate to the scope of the audit and independent of other services (§ 77 WTBG 2017). An offer such as “Statutory audit at a special price if we also handle your tax advice” contradicts this, and simultaneous involvement in bookkeeping or preparing the accounts is ruled out anyway under the independence rules of §§ 271 ff. UGB (Commercial Code).
LinkedIn, Google Ads, newsletters and cold outreach
For audit firms, LinkedIn is usually the most important social channel, because that is where managing directors, finance heads and supervisory board members read. Expert posts on new size categories, sustainability reporting or audits of associations are unproblematic. Only tag clients with their consent, and do not post photos from meetings in which documents are legible.

Google Ads are permitted, and the ad copy is subject to the same rules as your website. Do not use the names of other firms as search terms; that is risky under trade mark law and comes across as unprofessional towards colleagues. Because “Wirtschaftsprüfer” plus a place name is searched for relatively rarely, ad budgets here are often smaller than in tax advice. How to be found locally is shown in Local SEO for professional firms.
For newsletters and marketing emails, § 174 Abs. 3 TKG 2021 applies: you need the recipients' prior consent, including for businesses. There is an exception for your own customers whose address you obtained in connection with a service, if you advertise similar services of your own and offer an easy way to unsubscribe when collecting the address and in every message (§ 174 Abs. 4). Marketing calls without prior consent are not permitted (§ 174 Abs. 1), and that includes cold calling managing directors.
Your website as a recruiting tool
For many small audit firms, the bottleneck is not winning engagements but finding staff. Trainees also choose their employer based on how they can collect the practical experience required for the professional examination. A careers page that describes concretely which audits you carry out, how preparation for the examination is supported and how the season between January and June is organised has more impact than any slogan. The same applies here: only promise what you will deliver, for example on study time or course fees. Create the text of the ad, including the salary information under the collective agreement that is mandatory in Austria, with the free job ad generator.
The mandatory information for your website is summarised in Imprint for auditors in Austria. If you are also a tax adviser, read Advertising for tax advisers in Austria as well.
