Winning clients as a tax adviser: the right engagements instead of as many as possible

Most tax advisory firms have no problem getting enquiries at all. The problem is the wrong ones: the micro business that brings a shoebox of receipts in March, the request for a one-off return at a rock-bottom price, the company from an industry nobody on the team knows. This guide shows how, as a tax adviser in Austria or Germany, you can deliberately win the clients who suit your firm, which channels professional law allows and how your website politely says no to unsuitable enquiries.

Key points at a glance

  • Define two or three target groups, such as doctors, hospitality, founders or e-commerce, and align your website, profile and content with them.
  • Referrals from banks, lawyers and clients are the strongest channel, but without commission: § 84 WTBG 2017 in Austria, § 9 StBerG in Germany.
  • Your Google profile and the official directories (KSW member directory, Steuerberaterverzeichnis) are the foundation for being found.
  • Talks, newsletters and LinkedIn build trust; newsletters require consent.
  • A website with clear target groups and minimum requirements filters out unsuitable enquiries before they cost you time.

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.

Why the right engagements matter more than many

With staff in short supply, a firm's capacity is its most valuable asset. Every engagement ties up hours in bookkeeping, payroll and annual accounts, and unsuitable engagements tie up disproportionately many: because the industry is new, documents are chronically late or the fee doesn't cover the effort. If you deliberately win clients who suit the firm, you work more efficiently, can reuse knowledge and get recommended within your target group.

Winning clients therefore does not start with advertising but with a decision: who do you want to work for? Only then do you choose channels, and only then do you write the website.

Defining your target group and focus

Start by looking at your existing clients: which engagements are enjoyable, profitable and arrive with documents on time? Which industries do you and your team already know well? These answers usually point to two or three focus areas. Typical examples:

Examples of target groups and what they expect from your website
Target groupTypical questionsWhat the focus page should show
Doctors and health professionsSetting up or taking over a practice, contracted or private practice, group practiceHow a practice start-up works, typical deadlines, experience with health professions
HospitalityCash registers and their security requirements, tips, seasonal staff, payrollHow you take over till data, payroll for changing teams
FoundersLegal form, registering with the tax office, flat-rate taxation or small business schemeA start-up package with a clear process and timetable
E-commerce and online retailVAT on sales to other EU countries, marketplaces, payment providersExperience with interfaces and automated receipt processing

A focus is not a restriction but a promise. The dentist who reads on your website that you look after twenty practices and know the processes around chamber fees is more likely to call than a firm that serves “all industries”. Phrase focus areas factually and verifiably: “Focus on health professions” is unproblematic, “specialist” requires demonstrable knowledge and experience, expressly so in Germany under § 9(3) BOStB.

Referrals from banks, lawyers and clients

Most new engagements at tax advisory firms still come through referrals. Besides satisfied clients, other advisers are the most important channel: corporate relationship managers at banks, lawyers in company and inheritance law, notaries, management consultants, start-up centres, in Austria the WKO start-up service (Gründerservice), in Germany the IHK (chamber of commerce) and the chamber of crafts.

Good referral relationships are built on trust and quality, not commissions.

Professional law draws a clear line here: commissions for referring engagements are prohibited, in Austria under § 84 WTBG 2017, in Germany under § 9 StBerG. This applies in both directions. You pay the bank adviser nothing for founders sent your way, and you take nothing from the lawyer to whom you pass an inheritance matter. Rewards or vouchers for clients who recommend you are also ruled out. What is permitted and effective is anything that relies on quality.

How to get it right

  • Regular professional exchange with banks, law firms and notaries
  • Mutual recommendation because the quality is right
  • A short page on your website that partners can link to, for example for founders
  • Asking clients after a good annual review whether they would recommend you

Better avoid

  • Commission or a “tipster bonus” for referred engagements
  • A credit on the invoice for clients who bring someone along
  • Passing on enquiries to colleagues in return for a share
  • Portals that charge per referred engagement, without checking the terms carefully

More on building a referral network in the article Referrals for firms.

Google profile and directories

Even referred prospects google you before they call. Two entries should therefore be complete and up to date: your Google Business Profile and the official directory of your profession. In the Google profile, choose a suitable primary category such as “Tax consultant”, describe your focus areas in the description and under services, upload real photos and ask all clients equally for an honest review, without incentives. The article Google Business Profile for firms explains the details.

  • Austria: All licensed professionals are listed in the KSW member directory. Check your address, website and contact details.
  • Germany: The Steuerberaterverzeichnis (register of tax advisers) is kept by the Federal Chamber of Tax Advisers under § 86b StBerG; your Steuerberaterkammer supplies the data. In addition there are search services run by chambers and associations.
  • Private directories and business listings are worthwhile where your target group searches. Make sure name, address and phone number are written identically everywhere.

Which directories are really worthwhile is compared in the article Online directories for firms.

Talks, newsletters and LinkedIn

If you show what you know, you need to claim less. Three channels suit tax advice particularly well because they convey factual information, exactly what professional law requires.

  1. 1

    Talks and workshops

    At the start-up centre, the medical association, the hospitality association or the university of applied sciences: a talk on the first twelve months after founding a business reaches exactly your target group. Offer the slides on your website afterwards.

  2. 2

    Newsletter

    A client newsletter with deadlines, changes and tips for your target groups keeps you in touch and generates referrals. Marketing emails require prior consent, in Austria also from businesses (§ 174 TKG 2021), in Germany under § 7 UWG. Use the double opt-in procedure.

  3. 3

    LinkedIn

    Short professional posts on topics relevant to your target group, insights into the team, announcements of talks. The partners' personal profiles usually reach more people than the firm's page. Confidentiality applies here too: no client stories without approval.

What WTBG 2017 and StBerG allow

Tax advisers may advertise in both countries. The standards are similar, the legal bases differ.

Saying no online: clear target groups on the website

Your website is the best filter you have. A firm that writes “We serve businesses of every size and industry” gets enquiries of every size and industry. A firm that clearly describes its target groups and way of working gets fewer but better-matched enquiries, and spares itself awkward refusals on the phone.

How your website filters without seeming dismissive

  • Name your target groups on the home page: “We look after doctors, restaurants and founders in Salzburg.”
  • State your way of working clearly: “We work digitally, receipts come in continuously via our portal.” A downloadable document checklist shows which receipts you need.
  • Say honestly what you don't take on, such as one-off returns without ongoing support or certain industries
  • Explain your fee model or give an order of magnitude where professional law allows it
  • Ask for legal form, industry and matter in the contact form so you can judge before the meeting whether it fits
  • Have a friendly note ready for enquiries outside your target groups, for example pointing to the KSW member directory or the Steuerberaterverzeichnis

How to build the website as a whole is described in the article The website for your tax advisory firm; how to be found in search by your target groups in SEO for tax advisers. How to win over clients who want to move from another firm is shown in Switching tax adviser: a page for clients who want to change.

In brief

Questions on this topic

May I pay a bank a commission for referred clients?

No. Commissions for referring engagements are prohibited in Austria under § 84 WTBG 2017 and in Germany under § 9 StBerG, in both directions. Professional exchange and mutual recommendations based on quality are allowed.

Doesn't specialising in one industry hurt the business?

Usually the opposite. A clear focus makes your firm more visible and more recommendable for that target group, and you can reuse knowledge. You can still accept other engagements if they fit.

May I ask clients to recommend me?

Yes, asking for a recommendation is unproblematic. What is not allowed is giving something in return, such as credits, discounts or gifts.

May I introduce my services to businesses by email?

Only with prior consent, in Austria under § 174 TKG 2021 also with respect to businesses, in Germany under § 7 UWG. A letter or a talk at an association is the safer route.

How do I turn down unsuitable prospects without annoying them?

Ideally before they enquire: with clear target groups and a clear way of working on the website. If the enquiry still comes, a short, friendly reply pointing to the official directory, where suitable colleagues can be found, helps.
