This guide explains how and when to pay Pillar 2 top-up taxes (Domestic Top-up Tax and Multinational Top-up Tax).

When to pay

Payments must be made no later than:

• 30 June 2026, if the first accounting period the group is required to report Pillar 2 Top-up Taxes ends on or before 31 December 2024
• 18 months after the last day of the group’s accounting period, if the first accounting period the group is required to report Pillar 2 top-up taxes ends after 31 December 2024
• the later of 30 June 2026 and 15 months after the last day of the group’s accounting period for all other periods

If the deadline is on a weekend or bank holiday, make sure your payment reaches HMRC by the end of the previous working day.

What you need

You need your Pillar 2 ID reference. This is a 15-character reference number starting with X. This will have been provided when you registered.

If you do not have this, you’ll find it by signing into HMRC online services using your Government Gateway user ID.

If you use an incorrect reference number there will be a delay in the payment being allocated correctly.
