Tax settlement agreement: A new tool in the General Tax Code

19 May 2026 | Knowledge, News, Tax Focus, The Right Focus

A draft bill amending the General Tax Code (No. UDER110) has been submitted for consideration by the Council of Ministers. The bill introduces the tax settlement agreement (UDER110), a new form of amicable dispute resolution between taxpayers and the tax authority. The draft is open for inter-ministerial review and public consultation until 19 June, with the proposed date of entry into force being 1 January 2028. Below, we examine who may apply for a settlement agreement, when, and on what terms, and how the process may work in practice.

What is a tax settlement agreement?

A settlement agreement is a voluntary arrangement between the tax authority and a taxpayer or tax remitter (including their legal successors) concerning tax arrears.

The settlement agreement does not replace existing measures (e.g. payment relief[1]) but is a supplement to them, applying only to taxes that are classified as central government budget revenue; liabilities owed to local government units and non-tax budgetary liabilities are excluded.

Under a settlement agreement, the parties agree on the correct amount of the tax liability and the terms of repayment of the arrears. The process is always initiated by the applicant. Third parties liable for tax debts are not eligible to apply.

Reduced late payment interest – the key incentive to settle

The rate of reduction depends on when the application is filed:

Late payment interest ceases to accrue from the date the application is filed. No extension fee is charged either.

Tax relief – how does the process work?

An application may be filed from the date on which the tax arrears arise – during an audit or tax proceedings – but no later than the expiry of the time limit for commenting on the evidence gathered. All communication takes place exclusively via the taxpayer’s account on the e-Tax Office platform.

The authority has 30 days to issue a decision either to proceed with the negotiation or to refuse the application.

The negotiation stage is intended to be informal, with the authority free to request documents and arrange meetings to clarify matters. However, if the parties fail to reach an agreement within 3 months, the authority will refuse to conclude a settlement agreement. Once the settlement agreement has been drawn up, the applicant has 14 days to sign or reject it (failure to respond is treated as a rejection). For the agreement to take effect, a tax return, or a corrected return, consistent with the agreed terms, must be then submitted.

What effect can a tax settlement agreement have?

  • Termination of the audit and discontinuation of the tax proceedings
  • A prohibition on initiating new audits and issuing tax assessment decisions in respect of the matters covered by the settlement agreement
  • Exclusion of criminal liability for fiscal offences relating to the arrears in question
  • Suspension of the limitation period from the date the application is filed until the conclusion of the settlement agreement procedure

Tax settlement agreement – key limitations and risks

Inadmissibility of a settlement agreement

A settlement agreement is inadmissible where a tax assessment decision has already been issued and anti-avoidance proceedings are pending, where the liability arose from the application of penalty provisions or there is a suspicion of aggressive tax optimisation, or where the applicant has been convicted by a final and binding judgment or criminal fiscal proceedings are pending against them.

Lapse of the settlement agreement

A settlement agreement will lapse automatically in the event of a late repayment, resulting in:

  • An obligation to pay interest in full
  • Reinstatement of the authority’s right to conduct audits and tax proceedings
  • Exposure to criminal fiscal prosecution

Notably, where a settlement agreement has lapsed due to the applicant’s fault, a fresh application in respect of any tax liability may not be filed until an additional period of 3 years have passed.

One-shot rule and non-appealability

A further application in respect of the same liability will not be permitted, irrespective of the reason for which the settlement agreement procedure was terminated. A refusal to enter into a settlement agreement will not be subject to appeal or to review by the administrative courts.

Will taxpayers benefit from the tax settlement agreement?

The draft bill presents a genuine opportunity for the amicable resolution of tax disputes on reduced-interest terms. However, it demands careful preparation, given the one-shot nature of the application, the retroactive consequences of a lapse of the settlement agreement, and the absence of judicial review of a refusal to conclude one.

We therefore recommend monitoring the progress of the legislative process and conducting a preliminary review of any existing tax arrears with a view to taking advantage of this new instrument.

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.
