EVENT DETAILS

An updated draft bill to the Tax Ordinance and related acts, was published by the Ministry of Finance on August 4 this year. The draft bill will introduce important changes affecting businesses starting from July 2026, particularly regarding tax arrangements reporting (Mandatory Disclosure Rules – MDR).
On behalf of the AmCham Tax & Financial Services Committee, we invite you to a meeting entitled New Changes to MDR – How Will Taxpayers’ Obligations Change?
Our speakers will be Aleksandra Rutkowska, attorney-at-law and Head of the Tax Litigation practice, and Aleksander Brzozowski, tax advisor and senior associate in the Tax Litigation practice at Dentons, and we will cover the following key changes in MDR rules:

  • Exclusion of certain hallmarks and limitations on reporting for cross-border schemes – which transactions will no longer need to be reported?
  • Changes to the obligations of attorneys/legal advisors and tax advisors – will this lead to more responsibilities for their clients?
  • Updates to the definitions of key terms – how will these affect reporting requirements?
  • Removal of the category of “supporter” as a reporting entity – what impact will this have on other participants in tax arrangements?
  • Changes to reporting deadlines, penalties for non-compliance, and the need for MDR procedures – will this make compliance easier?
  • The expected timeline for the legislative process.

The meeting will take place on Monday, September 15, from 10:30 a.m. to 11:30 a.m. 
We encourage you to visit the AmCham office, Spektrum, ul. Twarda 18, 16th floor (live tickets are limited to 20 people, for those registering live, we ask to click the live ticket). The Webex link will be sent to all online attendees one day before the event.
