19 June 2026 · Mag. Bernhard Brandauer, Rechtsanwalt

At the start of every company transaction stands a fundamental setting of the course: does the buyer acquire the shares in the company or does it buy only individual assets? This choice between a share deal and an asset deal shapes the entire transaction, from liability through taxes to the structure of the purchase contract.

This post explains how the two forms of acquisition differ legally. The focus is on the universal succession in a share purchase as opposed to the singular succession in an asset purchase, the liability rules under section 38 UGB, section 1409 ABGB and section 14 BAO as well as the tax consequences and the importance of the warranties.

Anyone who knows these differences makes the structural decision deliberately. From a lawyer perspective, the choice of the form of acquisition decides which risks pass, which consents are needed and how the purchase contract must be built.

Classify your form of acquisition

Does a share deal or an asset deal suit your transaction?

Answer one or two questions on the form of acquisition and on liability. You receive an initial classification of the most important structural questions.

Already know you want to get in touch? Go straight to the enquiry form.

01 Question 1

Is it already settled whether you acquire shares in the company or individual assets?

In a share deal you buy the company as a whole, in an asset deal only selected assets. Both routes lead to very different liability and tax consequences.

All paths at a glance

Overview of all answers.

01

The choice of the form of acquisition should stand at the beginning of structuring.

Whether a share deal or an asset deal is the better choice depends on the target company, on the liability situation and on tax considerations. Clarify early which contracts, employees and assets are to pass and which risks you do not want to take on. This decision shapes the entire purchase contract.

A structured weighing of both routes before the start of the negotiation saves later corrections. The form of acquisition can be changed afterwards only with difficulty.

02

The structure is thought through, now the clean contractual implementation matters.

If the form of acquisition is chosen and liability and the transfer of contract are considered, the transaction is well set up. Check in addition whether employment law applies on the transfer of the business, whether real estate triggers real estate transfer tax and how the warranty catalogue maps the risks taken on.

A short legal review ensures that the chosen structure is consistently mapped in the contract and that no gaps remain.

03

Liability or the transfer of contract are unclear, sharpening them is advisable.

Unclear liability consequences or an ungoverned transfer of contract can become expensive after completion. Such points can be sharpened before signing: a precise list of the contracts to pass, the obtaining of the necessary consents and a warranty catalogue that addresses the known legacy risks of the company.

Have the structure reviewed before you sign. In a share deal you acquire the company together with its past; in an asset deal a missing consent can devalue an important contract.

The share deal: buying the company as a whole

In a share deal the buyer acquires the shares in the company, such as the business shares of a limited company. The target company continues to exist as a legal entity; only its owner changes. All contracts, receivables, liabilities, permits and employees remain with the company. One speaks of a universal succession at the level of the participation.

This route is often simpler to implement because not every individual asset has to be transferred. Contracts with customers and suppliers in principle continue, unless a change-of-control clause applies. The flip side is that the buyer acquires the company together with its past: known and unknown legacy risks, tax risks and disputes remain in the company.

Precisely for this reason warranties are especially important in a share deal. Because the buyer takes on the entire company with its history, a carefully negotiated warranty catalogue protects it against hidden risks. How this catalogue is built is shown in the post on the SPA warranty catalogue.

The asset deal: buying individual assets

In an asset deal the buyer acquires not the company but individual assets: machines, inventory, trademark rights, contracts or real estate. Each item is transferred individually; one speaks of singular succession. The principle of specificity applies, that is, every asset to pass must be precisely identified in the contract.

The advantage lies in the selection: the buyer takes on only what it wants to take on and can leave behind unwanted risks. The disadvantage is the greater effort. Contracts do not pass automatically. The transfer of a contract requires a transfer of contract, which as a rule needs the consent of the respective contract partner. Without this consent the contract stays with the seller.

In an asset deal too a business can pass as a whole. Then special liability rules and employment law apply, which the next section addresses. A deeper look at the transfer of individual assets is offered by the post on real estate in the asset deal.

Liability and taxes compared

In an asset deal several liability rules protect the creditors of the seller. If the buyer takes over a business as a going concern, it is in principle liable under section 38 UGB for the business-related liabilities, although this liability can be excluded under certain conditions. Section 1409 ABGB establishes a liability on the takeover of an estate or business, and section 14 BAO governs the liability for certain taxes of the predecessor.

In a share deal this question arises differently. Because the company remains in place as debtor, nothing changes in its liabilities. The buyer is not personally liable but bears the risk economically through its participation. For tax, on the acquisition of shares in companies holding real estate, real estate transfer tax can arise from a concentration of shares of 95 per cent.

In an asset deal the transfer of real estate immediately triggers real estate transfer tax. The tax bases and the depreciation options also differ. Which route is more favourable for tax can only be assessed case by case. The concept of the concentration of shares we explain in the glossary.

How the two forms of acquisition differ

These points decide on the suitable structure. Check each one before you settle the form of acquisition.

Comparison of share deal and asset deal by the most important legal and tax criteria
Criterion Share deal Asset deal
Object of acquisition Shares in the company Individual assets Selection of the desired assets
Legal succession Universal succession of the company Singular succession with specificity Every asset is transferred individually
Contracts In principle continue Transfer needs consent Contract partner must consent
Legacy risks Remain in the company Can partly be left behind Warranties more important in the share deal
Taxes Transfer tax from concentration of 95 per cent Transfer tax on transfer of real estate Consequences to be checked case by case

The tax assessment depends on the individual case and should be aligned with tax advice before the choice of the form of acquisition. The thresholds mentioned offer only guidance.

Caution in the choice of the form of acquisition: Whoever concludes a share deal without checking the liability situation takes on hidden legacy risks of the company. Whoever forgets the necessary consents in an asset deal loses important contracts. Have the structure reviewed before signing. Booking an initial consultation (72 euro) can quickly bring clarity.

Transfer of business and choice of structure

An important common feature of both routes is the transfer of business. If a business or a separable part of a business passes, the employment relationships transfer to the acquirer under the Employment Contract Law Adaptation Act. This applies regardless of whether the business passes through a share deal or an asset deal, provided the requirements of a transfer of business are met.

In a share deal this is usually the case from the outset, because the company and thus the business as a whole is preserved. In an asset deal it depends on whether the transferred assets form a business. Whoever underestimates the employment law consequences here risks unplanned obligations towards the employees. A deeper look is offered by the post on the transfer of business under AVRAG.

The choice of the form of acquisition is thus not only a question of taxes but also of liability and employment law. An initial assessment of the risks of your transaction is provided by our M&A transaction risk profile.

Frequent questions

Share deal versus asset deal.

What is the difference between a share deal and an asset deal? +

In a share deal you acquire the shares in the company, which remains in place as a legal entity. In an asset deal you buy individual assets, each of which is transferred individually. The share deal transfers the company together with its past; the asset deal allows a targeted selection of the desired assets.

Why are warranties especially important in a share deal? +

In a share deal the buyer takes on the company with its entire history, that is, also with known and unknown legacy risks, tax risks and disputes. A carefully negotiated warranty catalogue protects it against hidden risks, in that the seller stands in for certain features of the company and is liable on a breach.

Do contracts pass automatically in an asset deal? +

No. In an asset deal contracts do not pass automatically. The transfer of a contract requires a transfer of contract, which as a rule needs the consent of the respective contract partner. Without this consent the contract stays with the seller. Important contracts should therefore be identified early and the consents obtained in good time.
