Civil and tax aspects of settlement agreements on CHF mortgages and their implications for banks and consumers

17 March 2025 | Knowledge, News

The Swiss franc mortgage disputes have entered a new phase. More and more banks are concluding settlement agreements with borrowers, but tax settlements on this account are still highly controversial. The banks are therefore filing individual applications for tax rulings, but in the meantime the Supreme Administrative Court is developing a line of case law in the area of CIT that is negative towards them. At the same time, the Ministry of Finance does not rule out the possibility of issuing a general tax ruling on the waiver of the collection of PIT on certain income (revenues) and announced that it wants to familiarise itself with the structure of settlement agreements and resulting settlements and is open to arguments. It is therefore worth taking advantage of such ‘windows’, says Agata Dziwisz-Moshe, initiator of tax law workshops for representatives of banks operating on the mortgage market.

Problems with loan agreements in CHF

Swiss franc mortgages are one of the most complex issues in the Polish banking sector today. The history of these financial products dates back to 2000-2010, when banks offered the following products to their customers on a massive scale:

  • Mortgage credits indexed to or denominated in CHF
  • Mortgage loans also indexed to or denominated in CHF

Initially, these products were very popular due to their lower interest rates and greater availability compared to PLN loans. However, the sharp rise in the Swiss franc exchange rate after 2015 led to a dramatic increase in borrowers’ liabilities.

We currently see two main scenarios for the settlement of these agreements:

Judgments invalidating the loan agreement

As a result of a lawsuit filed by the borrower, the court may issue a judgment declaring the entire loan agreement invalid. In such a situation, the parties are obliged to return all benefits to each other – the borrower must repay the amount of the loan received and the bank must repay all instalments, fees and commissions charged.

The consequences of such a judgment are far-reaching for both the borrower and the bank, which must also account for such an operation from a tax perspective.

Settlement agreements between the parties

An alternative solution is a settlement agreement between the bank and borrowers. In the settlement agreement, the parties mutually agree on the method of settlement, taking into account the possibility that in the future a judgement could be issued declaring the loan agreement invalid. Usually, the parties expressly confirm in the settlement agreement that the validity of the loan agreement itself is not at issue.

Settlement agreements on CHF mortgage loans avoid lengthy litigation and give the parties more control over the terms of the settlement.

Tax aspects for banks

For banks, the tax treatment of amounts paid to customers as a result of both agreement annulment and settlement agreements, such as interest, loan fees, etc., has become a key issue. Financial institutions are seeking to include these sums in their own tax costs under the Corporate Income Tax Act.

We have written about the tax implications of CHF mortgage loan settlements here.

In order to confirm their method of handling such transactions, banks are requesting tax rulings.

What are the rulings of the Supreme Administrative Court?

With regard to settlements based on annulled agreements, the case law of the Supreme Administrative Court is consistent and negative for banks. Recently, the first negative rulings by the Supreme Administrative Court have begun to emerge, which make the consequences for banks of CIT settlements resulting from CHF mortgage loan settlement agreements the same as the consequences of annulled CHF mortgage loan agreements.

At the same time, at the end of last year, the Minister of Finance extended the application of the Ordinance on the waiver of the collection of PIT on certain income (revenues) [from settlement agreements on CHF mortgage loans] until the end of 2026, without, however, deciding to make any major changes to the structure of this waiver.

It should be borne in mind that both the civil law and tax issues of the settlement agreements on CHF mortgages and those related to the CIT and PIT settlements are interrelated, and the strategic argumentation of the Polish Bank Association (ZBP), which coordinates and represents the interests of the sector and, ultimately, the banks themselves in all these areas, should be consistent, coherent and uniform.

For this to happen, however, there must be a dialogue and exchange of experiences between the Settlement Agreements Group and the ZBP Tax Council on the civil law and tax implications of the settlement agreements on CHF mortgage loans.

There is still a willingness on the part of the Income Tax Department of the Ministry of Finance to listen to substantive arguments, including an openness to learn about the very structure of settlement agreements and the resulting settlements, which may lead to the issuance of a general tax ruling on PIT in the near future. In our opinion, it would be a pity to miss such a golden opportunity, says Agata Dziwisz-Moshe.

For this reason, the Head of our Tax Practice and Katarzyna Urbańska, Director of the Legal and Legislative Team at the Polish Bank Association (ZBP) invited the heads of the tax departments of banks and their general counsels involved in settlements of settlement agreements on CHF mortgage loans to a practical workshop on civil law and tax issues.

The main objective was to develop a comprehensive and balanced argumentation that could be used both in disputes on CIT and in discussions with the tax administration on PIT.

And it was a resounding success, because thanks to the synergy and cooperation with the two groups, we were able not only to identify problem areas, but above all to develop specific solutions and legal arguments that strengthen the position of the banks in their dialogue with the Ministry of Finance, while at the same time supporting the position of the borrowers themselves. This cooperation has shown how important it is to share experience and knowledge between experts from different fields in order to effectively solve complex tax problems, says Agata Dziwisz-Moshe.

Announcement of Income Tax Reform

On 19 August, during a press conference, the Prime Minister announced a package of tax changes planned for next year. According to the announcement, the reform is intended, on the one hand, to ease the burden on the middle class and, on the other, to shift a greater fiscal burden onto the wealthiest individuals and the largest companies. We take a look at the proposals included in the announced package and explain what they might mean for taxpayers.

Family foundations and the tax authorities: what draft bill UD447 proposes and why this is not the end of the troubles

Family foundations were intended to provide entrepreneurs with a stable framework for intergenerational wealth management. Yet not even four years have passed since the first such foundations were established, and the rules governing their taxation are set to be changed once again. This is because the scale of interest and the practical problems uncovered have overwhelmed the drafters of the legislation, as best illustrated by the figures – 927 applications for individual tax rulings and 77 opinions issued from the Head of the National Revenue Administration. This does not, however, mean that family foundations are being used on a massive scale for aggressive tax optimisation. A significant proportion of the queries concerned simply how to correctly apply the complex regulations.

NIS2 and the National Cybersecurity System Act in transport: what you need to do before October 2026

The amended Act on the National Cybersecurity System (UKSC) has been in force since 3 April 2026. For transport sector undertakings, this means a specific compliance timeline, including an obligation to register with the National Cybersecurity System (KSC) registry by 3 October 2026. Failure to do so may result in substantial financial penalties, coupled with the risk of personal liability for senior management. Not every undertaking, however, automatically falls within the scope of the new regime. Read on to find out whether your organisation is affected and what you need to do before the deadline for preparation.

Family foundations: the government has done the maths and presented the bill

Three years. That’s how long we’ve been waiting for what the Council of Ministers had seen in the data from the outset – and has now disclosed in its review of the Family Foundation Act. The document not only diagnoses the problems, but also previews substantial changes to rules that founders and their advisers treated as settled and stable. And therein lies a problem that goes far beyond tax matters. If the rules of the game are changed while the game is being played, there can be neither planning stability nor trust in the law. It is no coincidence that one of the greatest concerns among entrepreneurs considering setting up a foundation is not the level of taxation, but the stability of the legal framework – which today is once again being called into question.

What the new swiss franc act means for banks

We now have a new Act on Special Measures for the Adjudication of Cases Concerning Loan Agreements Denominated in or Indexed to the Swiss Franc. The provisions come into force 14 days after publication. So now is a good time to look at what lies ahead and what banks should be doing today.

New draft Pay Transparency Act – what has changed since December 2025?

A second version of the draft act on strengthening the application of the right to equal pay for equal work or work of equal value between men and women has now been published. It refines procedures and deadlines and introduces a new supervisory body. We have already discussed the changes affecting the recruitment stage and the three pillars of the forthcoming pay transparency framework, noting that Poland will miss the EU transposition deadline of 7 June 2026. Now, we take a closer look at the further changes, new developments and risks that have emerged in the latest, April version of the draft.

Payment Services Regulation (PSR) – between consumer protection and due diligence

The draft Payment Services Regulation (PSR) is one of the most significant elements of the reform of the EU legal framework for payment services. Its principal aim is to enhance the security of cashless transactions and to reduce the scale of financial fraud, in particular that arising from the growth of digital channels. At the same time, the new rules are intended to introduce a liability model that will not result in risk being transferred entirely to financial institutions, whilst retaining an important role for independent due diligence on the part of the user.

Energy deregulation – key changes for businesses and energy consumers

The President has now signed the Energy Deregulation Act (UDER92). The new provisions cover both the relationships between energy undertakings and consumers, and matters relating to investment, district heating, and the administrative obligations of energy market participants. The Act introduces changes in the areas of billing, communication with consumers, grid connection, and the operations of undertakings in the energy and district heating sectors. We set out the key points to note.

Banking sector overview | Banking today and tomorrow | July 2026

Under the draft legislation, banks will be required to offer existing borrowers a switch from WIBOR-based to POLSTR-based interest rates, a mechanism intended to speed up the voluntary transition of financial instruments to the new benchmark. The banking sector has responded positively to the proposal, according to Tadeusz Białek, President of the Polish Bank Association.
