1. Key GloBE compliance requirements
- Notification to the tax authority that the company falls within the scope of the GloBE rules
- Advance tax return and advance tax payment (QMDTT)
- Filing of the GloBE information return (GIR) and payment of final tax
2. Deadlines for companies with calendar-year financial year
| Obligation | Deadline |
|---|---|
|
Advance tax return and advance payment of Top-up Tax (QMDTT) for tax year January 1, 2024 – December 31, 2024 |
November 20, 2025 |
|
Notification of being subject to GloBE rules (Required if the entity is part of an in-scope MNE group in 2025) |
February 28, 2026 |
|
Filing of GloBE Information Return and final payment |
June 30, 2026 |
Please note that 100% of the calculated tax for 2024 must be paid as an advance by November
20, 2025. If the calculation was accurate, no further payment obligation will arise upon submission of the final GloBE information return. If there is a difference between the advance payment made as of November 20, 2025 and the final tax for 2024, the difference shall be paid to the tax authority until June 30, 2026 or the refund can be requested from this date.
A temporary relief is that, in the event the advance return is submitted with not final data, including
the amount of the expected final tax, the tax authority cannot impose a fine, late payment interest
or default penalty provided that the taxpayer acted as could reasonably be expected under the
given circumstances.
3. Companies with non-calendar financial year
For companies whose financial year does not coincide with the calendar year, the GloBE rules
apply to the first financial year starting in 2024. For example, if the financial year runs from October
1, 2024 to September 30, 2025, then the first GloBE tax year will be that period.
| Obligation | General deadline | Example (FY start: October 1, 2024) |
|---|---|---|
|
Notification of being subject to GloBE rules
(Required if the entity is part of an in-scope
MNE group in the financial year beginning in
2024) |
By the last day of the 2nd
month after the end of the
GloBE tax year |
November 30,
2025 |
|
Advance tax return and advance payment of
Top-up Tax (QMDTT) for financial year 2024 |
By the 20th day of the
11th month after the end
of the GloBE tax year |

|

Please note that for companies with non-calendar financial years, deadlines vary depending on the
actual start and end date of the tax year. We strongly recommend reviewing the specific timeline
relevant to your company.
4. Additional important notes
- GloBE notification and tax return obligations apply regardless of whether Top-up Tax is
actually payable in Hungary - Hungarian entities are individually responsible for fulfilling their obligations, even if the group-level reporting is handled by a foreign parent company.
- Non-compliance (e.g. failure to notify or file) may result in penalties or legal consequences,
as monitored by the Hungarian Tax Authority (NAV).
Should you have any questions regarding the Global Minimum Tax rules, your company’s potential obligations, or if you require assistance with the necessary steps, please do not hesitate to contact
us.
Since GloBE-related obligations are often handled centrally at the group level, we only address
GloBE compliance matters if we receive an explicit engagement to do so and accept that
engagement.
In case you engage us with the preparation and submission of the tax advance return, please note
that the Hungarian filing form for the GloBE tax advance return has not yet been published. It is
possible that, in connection with fulfilling this obligation, we may need to request additional
information from you that is necessary to prepare the return but is currently not available to us.
