Converting a shareholder loan into equity immediately cleans up the balance sheet and opens the door to further financing. However, many entrepreneurs mistakenly view capitalisation as a mere accounting operation and underestimate its implications. Our article will guide you through the current rules for 2026 and show you how to navigate the pitfalls of Czech corporate law and hidden tax traps safely.

The illustrative image shows an expert discussing the topic of capitalising a shareholder loan.

Key takeaways
  • Prohibition of non-cash contributions: Under Czech law, a shareholder’s receivable against their own company cannot be contributed directly as a non-cash contribution. The solution is a formal cash contribution paid up by way of a set-off agreement.
  • Immediate strengthening of creditworthiness: Converting a liability into equity significantly improves the balance sheet structure. This opens the door to better lending terms with banks.
  • Thin capitalisation optimisation: The transaction helps reduce the share of external funding relative to equity. This protects the company going forward in terms of the tax deductibility of interest on other loans.
  • Tax risk in the case of a discount: If a shareholder capitalises a receivable that they previously purchased below its nominal value, the difference between these amounts must be taxed at the moment of set-off.
  • Flexibility of an additional contribution: The complex process of increasing registered capital involving a notary can, in many cases, be replaced by providing an additional contribution outside the registered capital.

The concept of debt capitalisation and its essence

In everyday business practice, it often happens that an owner funds their company from their own resources. This results in long-term loans that the company is initially unable to repay.

At a certain point, however, these accumulated liabilities become an obstacle. Banks assess the company as over-indebted, business partners lose trust, and problems begin with the tax deductibility of interest.

The solution is debt capitalisation. The creditor (the shareholder) agrees with the debtor (the company) that instead of enforcing payment, they will convert the debt into an equity interest. The company thus immediately gets rid of the debt burden without having to generate any cash flow.

This transaction is essentially a barter. The shareholder’s receivable is extinguished and, in return, they obtain an increased ownership interest. The shareholder thereby changes their risk profile—they are no longer an ordinary creditor but become a pure investor.

The difference between capitalisation and debt forgiveness

One of the most fatal mistakes in practice is confusing capitalisation with ordinary debt forgiveness. Although the result in the form of relieving the company of debt may look similar at first glance, the legal and tax consequences are fundamentally different.

To set up capitalisation correctly and distinguish it from debt forgiveness, it is often crucial to have corporate documentation and procedures in order, which falls within the area of corporate law, holdings and structures.

In the case of debt forgiveness, the creditor unilaterally waives their claim. They receive nothing in return. For the company, however, this creates a major problem because it has been enriched free of charge. The extinction of the debt therefore generates taxable income for the company, from which it must pay 21% corporate income tax in the Czech Republic.

Capitalisation, by contrast, works on the principle of exact equivalence. The creditor does not forgive the debt but “buys” a corresponding share in the company’s assets. For the company, it is a contribution to equity that is not subject to taxation under any circumstances.

However, if you draft the capitalisation agreements unprofessionally or they lack mandatory statutory requirements, the Czech tax authority will reclassify the entire operation. Instead of a safe contribution, it will assess it as invalid and assess additional tax on the gratuitous income.

Types of receivables suitable for conversion into capital

Almost any monetary liability of a company towards a shareholder can be used for capitalisation. The most common are standard loan agreements, both interest-bearing and interest-free.

The practical differences as to when a purchase order is sufficient and when more detailed contractual documentation is safer are also summarised in the follow-up text Commercial contract vs. purchase order: When a purchase order is sufficient and when the company risks a problem.

Unpaid invoices from business dealings are also very often capitalised. For example, situations where a shareholder provided consulting services to the company or leased real estate to it and the company did not have the funds to make these payments.

However, receivables acquired by assignment require special caution. If a shareholder buys their company’s debt from a bank or a third-party supplier at a discount and then capitalises it in full, they may fall into a tax trap.

Contractual penalties or unpaid default interest are also a major issue. Until these amounts are actually paid, the shareholder typically does not tax them. However, set-off in the context of capitalisation is treated by law as payment, so the shareholder must tax this income immediately.

To ensure that the effects of set-off are properly captured in the accounting records and subsequently in tax returns, it is advisable to set up internal processes for accounting services.

Related questions on types of receivables

1. Can I capitalise a receivable that is already time-barred?
Czech law does not exclude this. A time-barred receivable can be used for set-off if the debtor (the company) expressly agrees and does not raise a limitation defence. However, the general meeting must clearly approve this step.

2. Is it possible to cross-capitalise receivables from different companies within a holding group?
The transaction is always tied to the creditor–debtor relationship. If you owe money to a subsidiary, it cannot be directly set off against a contribution in the parent company. More complex holding structures require a series of successive set-offs and receivables assignment agreements.

3. Can I capitalise a loan that I provided to the company in a foreign currency?
Yes, but for the purposes of increasing capital in Czech crowns, you must convert the foreign-currency receivable into CZK. The conversion typically uses the exchange rate applicable on the date the set-off agreement is concluded, and any resulting exchange differences must be properly accounted for and settled for accounting and tax purposes in the company.

Corporate rules and the prohibition of non-cash contributions

The Business Corporations Act (ZOK) contains very specific protective mechanisms for contributions consisting of shareholders’ receivables. Many owners of Czech limited liability companies (s.r.o.) believe that it is sufficient to have the debt valued by an expert and simply contribute it as a non-cash contribution.

However, such a procedure is expressly unlawful. Section 21(3) of the ZOK prohibits a shareholder’s receivable against the company from forming the subject matter of a non-cash contribution. The legislator seeks to prevent artificial increases of capital through fictitious debts.

The only permissible route is therefore to use a so-called cash contribution. The process works so that the shareholder formally undertakes to contribute money to the company, and this debt towards the company is immediately set off against the shareholder’s historical receivable. The outcome is the same, but the legal route is entirely different.

This step does not require an expert valuation report. The nominal value of the debt is simply used as the value of the contribution. What is crucial, however, is flawless contractual documentation.

The process of increasing registered capital

If you choose the route of increasing registered capital, be prepared for a highly formalised process. It requires close cooperation with a notary and subsequent registration in the Commercial Register in the Czech Republic.

As a first step, the general meeting must be convened, and the notary will draw up a notarial deed. The general meeting must decide on the increase of the registered capital and expressly allow that the contribution will be paid up by set-off of a specific receivable.

The resolution of the general meeting must include an exact specification of the receivable to be set off as well as approval of the wording of the set-off agreement. If the resolution does not include approval of the agreement wording, the subsequent set-off is absolutely invalid.

Only after this resolution does the shareholder sign a declaration on assuming the contribution obligation and then promptly concludes the approved set-off agreement with the company. The final step is filing an application with the registry court, which makes the increase effective vis-à-vis third parties.

Related questions on the formal process

1. How long does the entire capital increase process take?
If you have all accounting documents prepared, the notarial process itself and preparation of the agreements takes a few days. The subsequent entry in the Commercial Register is usually made promptly, at the latest within 5 business days from filing the application.

2. Do I have to bring the accounting records or the original loan agreements to the notary?
The notary typically requires confirmation from the statutory body (or an independent auditor) that the receivable being set off actually exists and is properly recorded in the accounts. Notaries usually do not review the loan agreements themselves, but you must have them ready.

3. Can I sign the set-off agreement before the general meeting takes place?
Absolutely not. The draft set-off agreement must first be expressly approved by the general meeting in its resolution. If you signed the agreement prematurely, it would be absolutely invalid by law and you would have to repeat the entire capital increase process at significant cost.

Alternative: Additional contribution outside registered capital

Increasing registered capital may look prestigious, but it is administratively costly and relatively rigid. However, there is a more elegant and faster solution – an additional contribution outside registered capital.

In this case, there are no changes to the articles of association and you can do without a notary. The company’s equity is strengthened in accounting terms through so-called other capital funds. For banks and insolvency tests, it has exactly the same rescue effect.

The shareholder undertakes to provide a cash additional contribution and again promptly pays it up by setting off their receivable. A general meeting decision is sufficient in ordinary written form, without the need for notarisation.

The disadvantage of this solution is that it is very difficult to get the additional contribution back out of the company. Repayment of the additional contribution is subject to strict balance-sheet tests. The shareholder can no longer withdraw the money as easily as when it was a standard loan.

Possible issues

How ARROWS helps (office@arws.cz)

Insufficient documentation for the receivable: Unclear legal basis, missing agreements, unproven actual provision of funds in the case of loans.

We will review the contractual and accounting documentation, establish a clear legal basis, and ensure the transaction safely withstands a tax audit in the Czech Republic.

Errors in the general meeting resolution and set-off: Risk of invalidity of the capital increase due to formal inconsistencies with the ZOK.

We will prepare complete, watertight documentation from the draft resolution, through the set-off agreement, to the documents for the notary and for the Commercial Register.

Unexpected taxation upon capitalisation: Additional assessments due to discounting of assigned receivables or incorrect release of value adjustments.

We will carry out a preliminary impact analysis, identify hidden risks, and propose a structure minimising tax leakage.

Risk under the thin capitalisation test: Incorrect setting of the equity-to-debt ratio impairs the tax deductibility of other interest.

We will assess the impact of capitalisation on the excessive borrowing costs tests and propose the best route to balance the holding’s balance sheet.

Tax implications for the company (Debtor)

From the company’s perspective, the accounting set-off and the capital increase are completely tax neutral. The extinguished liability becomes a permanent source of asset coverage and therefore does not generate any profit for corporate income tax purposes under Czech law.

However, capitalisation brings a huge positive effect in the area of tax deductibility of other interest. Under Czech law, the so-called thin capitalisation rule applies. It states that if a company has too much debt towards related parties (more than four times its equity), it cannot treat interest on such debts as tax-deductible expenses.

By capitalising the debt, you affect this formula on two fronts at once. At the same time, your total volume of debt decreases and, mathematically, your equity increases. The test result therefore improves sharply.

It should be emphasised, however, that this effect works exclusively going forward. If the tax authority disallowed your interest in past years, the current capitalisation will not retroactively remedy anything.

Tax implications for the shareholder (Creditor)

Standard capitalisation of a loan is straightforward for the shareholder. The value of the extinguished debt is simply rolled into the acquisition cost of their ownership interest. They will use this value as a tax-deductible expense only at the moment they decide to sell their interest in the company.

But beware of exceptions that trigger a tax liability. The first are tax value adjustments. If, as a creditor, you previously reduced your tax base in your accounts by creating value adjustments for an unpaid loan, you now have a problem.

At the moment of capitalisation, the receivable legally ceases to exist. With its extinction, the reason for the value adjustment also falls away. You must release this item immediately, which will unexpectedly and one-off increase your income tax base for that year.

Another risk is penalty charges. Have you converted into an equity interest a debt that consisted of contractual penalties or unpaid interest? The tax authority treats set-off as payment, so you must pay tax immediately upon signing the agreement on these previously untaxed accessories.

Related questions on a shareholder’s taxes

1. How is the situation taxed if I capitalise a debt purchased at a huge discount?
This results in harsh taxation. If you buy a debt for CZK 1 million and its nominal value (which you capitalise) is CZK 5 million, you realise a profit of CZK 4 million upon set-off. You must immediately pay income tax on this difference.

2. How do I prove the acquisition cost of the equity interest to the tax authority for the future?
You must carefully archive all documents relating to the capitalisation (the set-off agreement, the general meeting resolution, bank statements for the original loan). The authority may want to see them even ten years later if you decide to sell your equity interest.

3. Do I have to tax interest on a loan if I capitalise it together with the principal?
Yes—this is where an unpleasant tax trap lies. For tax purposes, the set-off of a receivable is considered its actual payment. If you therefore capitalise previously untaxed interest or contractual penalties, you must tax them immediately upon signing the agreement as your income.

Insolvency risks and the challengeability of set-offs

Very often, capitalisation is carried out at a time when the company is balancing on the edge of bankruptcy and the shareholder is trying to save it. This brings the very strict rules of the Czech Insolvency Act into play.

Set-off of receivables before insolvency is heavily regulated by law. If the company is unable to avert insolvency and enters insolvency proceedings, the insolvency administrator will start scrutinising all steps taken. They can very easily challenge and invalidate the set-off agreement.

Insolvency administrators classify this as a so-called preferential legal act. They argue that, through set-off, the shareholder avoided the standard insolvency process and enriched themselves at the expense of the company’s other ordinary creditors.

If the court cancels the set-off, the shareholder’s contribution obligation revives. The shareholder will be forced to inject real money into the company, and their original debt will fall into the insolvency proceedings, where they will recover only a negligible fraction. Ensuring corporate immunity is therefore absolutely key here.

Process errors and tax audits

Tax authorities are very fond of auditing capitalisations. Typically, they look for whether it was a disguised way of forgiving a debt or a purposeful attempt to meet thin capitalisation tests through fictitious documents.

Officials primarily verify the substantive nature of the transaction. They examine whether the original loan actually existed. They therefore commonly require bank statements confirming the movement of funds from several years ago. Without them, they will label the set-off as fictitious.

We also often encounter fatal procedural mistakes. Shareholders sign the set-off agreement before the general meeting has even decided on the capital increase. Such a step renders the entire transaction absolutely invalid.

In such situations, the contribution is deemed unpaid, and any distribution of profit or further corporate steps constitute a gross breach of the duty of due managerial care. Without expert legal supervision, such operations become a huge risk.

Final summary

The conversion—capitalisation of a shareholder’s receivable—is a highly effective way to rid a company of debt and immediately improve its financial health in the eyes of banks and partners. The burden of external liabilities is transformed into equity without the need to inject new cash into the business.

However, this is not merely a simple accounting transfer. The Czech Business Corporations Act expressly prohibits a direct non-cash contribution in the form of shareholders’ debts. You must therefore always structure the transaction as a formal cash contribution (or, as the case may be, an additional contribution), which is paid up through a carefully timed set-off agreement.

The key pitfalls lie in tax and insolvency details. An incorrect set-off at a time when the company is facing impending insolvency, failure to tax discounted receivables, or an incorrect calculation of thin capitalisation tests can mean fatal financial risk for both the company and the owner.

A reliable defence against invalidity of acts and additional tax assessments is meticulous legal and tax preparation. Experienced experts from ARROWS advokátní kancelář (office@arws.cz) will guide you safely through the entire process and tailor the transaction precisely to your business.

FAQ – Most common questions on capitalisation of receivables

1. What is the main difference between capitalising a receivable and simply forgiving a debt?
With forgiveness, you lose the debt without any consideration, which for the company means gratuitous income on which it must pay 21% corporate income tax. Capitalisation, by contrast, is a fair exchange—for the cancelled debt you receive a stronger equity interest in the company, so you elegantly avoid taxation.

2. Can capitalisation of a receivable save the tax deductibility of interest on other loans?
Absolutely. By reducing the company’s overall debt while strengthening its equity, you will dramatically improve the limits for thin capitalisation testing. Interest on other loans can then again be booked as tax-deductible expenses without concern.

3. Do I need an expert valuation report to value a personal loan for capitalisation?
If you structure the transaction correctly through a cash contribution and a set-off agreement, you do not need an expert valuation report. The debt is valued in the standard way at its nominal amount. You would only need an expert for non-cash contributions, which the law prohibits for shareholders’ debts anyway.

4. Does loan interest become a tax-deductible expense at the moment it is capitalised?
Yes. If you are an individual and the company has not yet paid you the interest (and therefore has not booked it as a tax expense), then through set-off upon capitalisation the debt is treated as fictitiously repaid. The company can book it as an expense, but you must pay income tax on it at that same moment.

5. What is the tax impact if an additional contribution outside registered capital is potentially returned in the future?
If the company starts doing well in the future and the general meeting pays your earlier additional contribution back to you, it will be taxed as ordinary income from capital assets. The company will withhold 15% tax, but the tax base can be smartly reduced by the acquisition cost of your equity interest.
