Tax advice for real estate: how to win landlords and investors online

Landlords and property investors are attractive clients for tax firms: recurring returns, large amounts, clear questions. But they don't look for you all year round; they look at a specific moment: when buying, when selling, when letting for the first time or after an inheritance. This guide shows how tax advisers in Austria and Germany get found at exactly these moments, which pages and topics make that happen, how to handle prices and enquiries, and how estate agents, property managers and notaries can refer clients to you without you breaching your professional rules.

Key points at a glance

  • Real estate mandates arise from specific occasions: purchase, sale, first letting, inheritance. Give each occasion its own page instead of one catch-all “real estate” page.
  • Write in the words of your clients and your country: “Steuerberater Immobilien Vermietung” (tax adviser real estate letting), ImmoESt and input VAT in Austria, the speculation period, depreciation (AfA) and the 15 % threshold in Germany.
  • Landlords compare prices: a price range per property and a short enquiry form filter better than “price on request”.
  • Online works if the way you work together is clearly described; for “near me” searches you still need a well-kept Google profile.
  • Estate agents, property managers and notaries are strong referral partners, as long as no commission is paid (§ 84 WTBG 2017, § 9 StBerG).

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.

How landlords and investors search for tax advice

Someone who lets a flat or buys an apartment building rarely searches for “tax advice” in general. They search with a specific occasion and often under time pressure: the purchase contract is with the notary, the first rent has come in, a sale is coming up and the question is whether tax will be due. The typical search terms show this clearly: “steuerberater immobilien vermietung” (tax adviser real estate letting), “steuerberater immobilienkauf” (tax adviser property purchase), “steuerberater immobilien kosten” (tax adviser real estate costs) or simply “steuerberater immobilien in der nähe” (tax adviser real estate near me).

For your website this means two things. First, there has to be a page for each of these occasions that answers exactly this question. Second, demand is sporadic: a landlady with two flats needs you every year for her return, but advice on a purchase perhaps only every ten years. If you are not found at the decisive moment, you lose the mandate to the firm that happens to rank first. In the long run you therefore win real estate clients not with a single campaign but with pages that are found all year round.

Search occasions and what searchers want to know at that moment
OccasionTypical searchWhat the page must answer
First lettingsteuerberater vermietung, steuererklärung vermietungWhich income, which expenses are deductible, when a return is needed, what you take over
Buying an investment propertysteuerberater immobilienkauf, steuerberater immobilien investorWhat to clarify before signing: split between land and building, financing, VAT, legal form
Saleimmobilienertragsteuer (AT), spekulationsfrist immobilie (DE)Whether tax is due, roughly how much, which exemptions exist, who calculates what
Inheritance or giftsteuerberater erbschaft immobilie, immobilie schenken steuerReal estate transfer tax or inheritance tax, continued letting, a later sale
Several properties, portfoliosteuerberater immobilien gmbh, vermögensverwaltende gmbhWhen a company may pay off and what speaks against it, without blanket promises

Pages by occasion instead of one “real estate” page

Many firms list real estate as a keyword in a list of services: “Vermietung und Verpachtung” (letting and leasing) between payroll and reorganisations. That is enough neither for Google nor for people. A separate page per occasion ranks for the matching search, can be forwarded by estate agents as a link and answers the questions that would otherwise fill the initial meeting. How to build a single service page is described in the guide on practice areas on the firm website; which pages a tax firm needs overall is covered in The website for your tax advisory firm.

A possible page structure for real estate mandates
PageFor whomWhat belongs on it
Tax advice for landlordsPrivate landlords with one to ten unitsAnnual return, deductible costs, depreciation, documents per year, price range per property
Property purchaseBuyers of investment propertiesTax questions before signing, how purchase advice works, what you need for it
Property saleSellers of private propertyImmoESt (AT) or private sales transactions (DE), exemptions, working with the notary
Inheriting and gifting propertyHeirs, families, people handing over propertyTaxes on transfer, questions about continued letting or a sale afterwards
Investors and property companiesThose who hold or develop several propertiesLegal form questions, accounts, financing talks, ongoing support

Each page opens with a sentence that addresses the occasion and ends with a clear next step. Two examples of an opening that matches the search:

  • “You let a flat in Vienna and don't know what you can deduct? We prepare your return on income from letting and leasing and tell you in advance what it costs.”
  • “You want to sell a let flat and wonder whether the speculation period has already expired? We check this before the notary appointment so there are no surprises afterwards.”

Stay factual. “Real estate specialist” or “expert in property taxation” should only appear where you can prove experience and knowledge, for example through the number of landlords you advise, talks or further training. In Germany § 9(3) BOStB expressly requires this, and in both countries misleading advertising is not allowed. Firms that occupy a niche this clearly benefit in particular; how to find and show a specialisation in general is described in Finding a niche and showing it on the website.

Topics real estate clients search for

Expert articles work particularly well for real estate firms, because the questions are very specific and are asked again every year. It is important to use the terms of your country. An article on the “Spekulationsfrist” (speculation period) helps nobody in Graz, and a text on ImmoESt is not searched for in Berlin. The overview below shows the topics searched for most often in both countries. The figures are as of the publication date of this post; check them before publishing them on your website.

Common real estate tax topics in Austria and Germany
TopicAustriaGermany
Sale of private propertyImmobilienertragsteuer (ImmoESt, real estate income tax): special tax rate of 30 % on the capital gain (§ 30a EStG 1988), regardless of the holding periodTaxable only within 10 years of acquisition (§ 23(1) no. 1 EStG), at the personal tax rate
Important exemptionsMain residence exemption, exemption for self-built property; flat-rate calculation for so-called old assets (Altvermögen)Own use in the year of sale and in the two years before
Who calculates the taxUsually the notary or law firm as party representative by way of self-assessment (§ 30c EStG 1988)The tax office via the sellers' income tax return
Depreciation of the buildingUsually 1.5 % per year for residential letting; the land share is not depreciatedStraight-line 2 %, 2.5 % if completed before 1925, 3 % for residential buildings completed from 2023 (§ 7(4) EStG), for new residential buildings under conditions 5 % declining balance (§ 7(5a) EStG)
Renovation after purchaseDistinction between maintenance, repair and construction, with different spreading over time15 % threshold: renovation of more than 15 % of the building's acquisition costs in the first three years counts as construction costs (§ 6(1) no. 1a EStG)
VAT on lettingResidential letting generally at 10 % VAT with input VAT deduction; input VAT adjustment for real estate over a long periodResidential letting VAT-exempt (§ 4 no. 12 UStG), option only for commercial letting to businesses (§ 9 UStG)
Real estate transfer tax3.5 % on purchase; for gratuitous acquisitions a tiered rate from 0.5 % to 3.5 % of the property value (§ 7 GrEStG 1987)Between 3.5 % and 6.5 % of the purchase price, depending on the federal state
Evergreen topicsLiebhaberei (hobby activity) with long-term losses from letting, short-term rentalsProperty tax after the reform (new values since 1 January 2025), holiday homes, losses from letting

Austria: ImmoESt, letting and leasing, input VAT

In Austria the Immobilienertragsteuer (real estate income tax) is the strongest search topic, because since 2012 it has in principle applied to every private sale of land. A good article explains the 30 % rate, the main residence exemption, the flat-rate calculation for old assets and, importantly for working together, that usually the notary or law firm pays the ImmoESt as part of the self-assessment. Your role as a tax adviser lies before that (checking exemptions, determining acquisition costs) and after it (return, option for standard taxation, losses).

For income from Vermietung und Verpachtung (letting and leasing), clients search for deductible costs, depreciation and the split between land and building. Input VAT is about whether it pays to waive the small business exemption, about the 10 % VAT on residential rents and about the input VAT adjustment if a flat is later sold VAT-free or used privately. These topics are well suited to short, dated articles with a worked example without client data.

Germany: speculation period, depreciation, property tax, 15 % threshold

In Germany sellers mainly search for the Spekulationsfrist (speculation period): under § 23 EStG a private sale is only taxable if no more than ten years lie between acquisition and sale, and not even then if the owners lived in the property themselves in the year of sale and in the two years before. Buyers ask about AfA (depreciation), i.e. how much of the purchase price they can write off each year, and about the 15 % threshold: anyone who spends more than 15 % of the building's acquisition costs (excluding VAT) on renovation in the first three years after purchase cannot deduct these costs immediately but has to depreciate them over the useful life.

The Grundsteuer reform (property tax reform) brought many owners to tax firms, but for you it is often a lot of work for little fee. Use the topic on the website as an entry point, not as a main service: an up-to-date article that explains questions on assessment notices and objections in general terms, and at the end a reference to your ongoing support for landlords.

Prices and enquiries: landlords compare

Private landlords are price-conscious. Many did their return themselves before and wonder whether a firm is worth it. If your website says “fee by agreement”, you get enquiries that disappear after the first quote and calls that only ask about the price. An honest price range filters better.

Two people compare figures on a printed quote
Landlords compare quotes: a clear price range per property answers the first question before the call.
  • Price per property or unit: “Return on letting and leasing for one flat from … euros, each additional unit from … euros.” State what is included and what costs extra (initial set-up, purchase advice, input VAT adjustment).
  • Occasion-based advice separately: purchase review or sale advice as a flat fee or by the hour, with an honest range.
  • Austria: fees can be agreed freely; state clearly whether prices are gross or net.
  • Germany: the StBVV (tax advisers' fee regulation) also applies to returns on letting and leasing. Flat fees and deviating fees require an agreement in text form (§ 4 StBVV); phrase prices on the website as “from” or as an example.

The enquiry form only asks what you need for an assessment: occasion (letting, purchase, sale, inheritance), number and type of properties, location, whether there is already a tax number or returns from previous years, and the desired timing. Purchase and rental contracts only come via the portal after the initial meeting. A list of the documents you need, such as the purchase contract, rental contracts, loan agreement with interest statement, service charge statements and invoices for repairs, saves you and your clients follow-up questions.

Document list for landlords

Create a free document checklist for letting, purchase or sale that you can link on the website or send after the initial meeting.

Does “online” work for real estate mandates?

Yes, and for landlords often better than for other clients. Someone who lives in Vienna and lets in Graz, or holds a flat in Leipzig from Munich, is not tied to any location. The documents are manageable and easy to send digitally: rental contracts, bank statements, statements from the property manager. Searches like “steuerberater immobilien online” (tax adviser real estate online) are rarer than local ones, but they have a clear intent.

  1. 1

    Describe how you work together

    How documents arrive (portal, upload, app), when in the year you need them, how meetings work (video, phone, in person).

  2. 2

    Write for the whole country

    Say that you advise landlords across the country, and still name your location so that local searches work.

  3. 3

    Keep your Google profile up to date

    For “tax adviser real estate near me” the profile decides: category tax adviser, services related to real estate, current photos.

  4. 4

    Mind the country differences

    Austrian firms do not automatically advise on German property. If you work across borders, say exactly for which country and with whom.

A note on scope: many people with real estate questions actually have a tenancy law problem, such as a rent increase, a notice of termination or a dispute over service charges. For the website this means: clearly define what you do on the tax side, and recommend a law firm for legal questions. How firms position themselves in tenancy law is described in Tenancy law: positioning for landlords or tenants; such a firm is an obvious partner.

Estate agents, property managers, notaries: your referral network

The most common objection from real estate tax advisers is: “My business comes through estate agents and notaries.” That is often true. But this referral, too, ends with a Google search for your name, and then the website has to confirm what the agent said. Website and network are therefore not opposites: the website makes you referable. How this works in general is described in the guide Referrals and network for firms.

Referral partners in real estate
PartnerWhen the question comes upWhat you can give them
Estate agentsWhen selling (“Do I have to pay tax on this?”) and when buying an investment property (“Does it make sense tax-wise?”)A link to your purchase and sale pages, business cards, a short expert talk for the team
Property managersWith the annual statement, with renovations and with a change of ownerNotes on which figures in the statement landlords need for their return, a document list
NotariesWith the purchase contract, gift and handover; in Austria with the self-assessment of real estate transfer tax and ImmoEStProfessional exchange on preliminary tax questions; notaries are impartial and refer with restraint
Lawyers in tenancy and property lawWith disputes, rental contracts and condominium ownershipMutual referrals for the other side of the question
Banks and financing advisersWhen financing an investment propertyDocuments on rental income, a conversation before the loan decision
Two stacks of blank white business cards on a light surface
A stack of cards with a QR code at the estate agent's or property manager's office makes passing you on easy.

Good partners refer you when they know exactly what you stand for. “Does taxes” is a weak referral; “She checks before the notary appointment whether ImmoESt is due on the sale” is a strong one. Give estate agents and property managers links to individual pages rather than the home page, and leave them a business card with a QR code to the matching page; you can use the business card generator for this free of charge.

If you show partnerships on the website, do it so that it remains clear: these are separate businesses with their own services. And ask in the initial meeting or in the form how clients found you. After a few months you will see which estate agent or property manager really refers you and where a coffee to maintain the relationship is worth it.

Common mistakes on websites of real estate tax firms

How to get it right

  • One page per occasion: letting, purchase, sale, inheriting and gifting
  • Terms of your own country: ImmoESt and input VAT in Austria, speculation period and AfA in Germany
  • A price range per property and clarity on what costs extra
  • Dated expert articles with invented worked examples
  • Links and business cards for estate agents and property managers that lead to the matching page

Better avoid

  • “Real estate” as one keyword in a long list of services
  • “We guarantee you'll pay no tax on the sale”
  • Answering tenancy law questions as if they were tax questions
  • Tax rates and thresholds from three years ago that nobody has updated
  • Referral bonuses for estate agents or discounts for referred clients

In brief

Questions on this topic

Is a separate page for real estate mandates worth it for a tax firm?

Yes, if you want to advise landlords or investors in a targeted way. One page per occasion (letting, purchase, sale, inheritance) ranks for the matching searches, can be forwarded by estate agents and answers questions that would otherwise fill the initial meeting.

May I pay estate agents a commission for referred clients?

No. In Austria § 84 WTBG 2017 prohibits commissions for arranging mandates, in Germany § 9 StBerG. Mutual professional referrals without anything in return are allowed.

Should I state prices for the letting return on my website?

A price range per property helps because landlords compare. In Austria fees can be agreed freely. In Germany the StBVV applies; flat fees require an agreement in text form, so state prices as “from” or as an example.

Which topics are suitable for articles on real estate taxation?

In Austria mainly ImmoESt, the main residence exemption, letting and leasing, input VAT and real estate transfer tax. In Germany the speculation period under § 23 EStG, depreciation (AfA), the 15 % threshold and property tax. Date every article and check figures regularly.

Can I advise landlords purely online?

Yes. The documents are easy to send digitally, and many landlords own properties in other cities. Describe the process specifically and still name your location so that you are also found in “near me” searches.
