As the end
of the year approaches, businesses face not only closing tasks but also a
series of strategic decisions and various deadlines. We have compiled the most
important dates and tasks to ensure that the 2025/2026 year-end closing goes as
smoothly as possible.
November Deadlines: Group Taxpayer Status and GloBE QDMTT
1–20 November – Creation of Group Taxpayer Status
During this
period, applications can be submitted for group corporate taxpayer status for
2026. This opportunity is particularly important for larger corporate groups
with multiple members.
20 November – GloBE QDMTT advance payment
Taxpayers
with a calendar tax year must declare and pay the qualified domestic minimum
top-up tax (QDMTT) for the 2024 tax year by 20 November, in accordance with the
global minimum tax (GloBE) rules.
December decisions: currency, transfer pricing, and KIVA
1 December – Taxpayment in euros or dollars
If you wish
to pay your corporate or local business tax in euros or US dollars, you must
make the choice by December 31 at the latest. The decision applies to the
following tax year and can be made using the standardized form provided by the
National Tax and Customs Administration (NAV).
LeitnerLeitner’s consultants approach your company’s unique and specific issues with a comprehensive mindset while remaining practical. Therefore, you can be confident that whichever of the listed deadlines, obligations, or choices affect you, your matter is in safe hands!
December 31 – Transfer Pricing Reports and Master File
At the end
of the year, it is worth paying attention to several transfer pricing
deadlines:
- If the Hungarian company is responsible for preparing the country-by-country report (CbCR) or for submitting it to the NAV, the deadline is December 31.
- If the Master File is prepared by the ultimate parent company, the 2024 document must also be available by December 31.
- It is worth reviewing the previous benchmarks, as any necessary adjustments may affect transfer prices, reporting, profits, and the tax payable.
December 31 – Transition to KIVA
Smaller
businesses may consider switching from corporate tax to the small business tax
(KIVA). KIVA takes effect on the 1st day of the month following the
notification. If a company wishes to become subject to KIVA from January 1,
2026, the notification must be submitted in December 2025. This helps reduce
administrative burdens and avoid duplication of closing tasks.
December 31 – Advance Retail Tax for Platform Operators
New
platform operators and certain foreign online sellers must pay the advance by
December 31. The advance tax is payable in two instalments: upon registration
and by the last day of the tax year.
Important tax deadlines for the first half of 2026 February 28 – GloBe filings
Calendar-year
taxpayers must submit the GloBE filing for 2025 by February 28, which indicates
whether the company is subject to the GloBE top-up tax and presents the
multinational or large domestic corporate group.
May 31 – Tax returns, financial statements, and public CbCR
June 30 – GloBe: QDMTT, Information Return (GIR)
Those who have now become subject to the domestic top-up tax can submit their 2024 QDMTT return by June 30. If no other member of the corporate group files elsewhere, the group-level GloBE Information Return (GIR) is also due by this deadline.
Attention: Changes in the 2026 Tax Package
The 2026
tax package was submitted for public consultation in October 2025 and is
currently awaiting parliamentary approval. It includes changes affecting
several types of taxes, so it is advisable to monitor the developments and
prepare for them in a timely manner.
