The deadline appears to be this week for the current tariff-refund filing rush, with reporting on June 29–30, 2026 saying companies were moving fast ahead of that cutoff. The available reporting also says the refund system is currently limited to entries finalized in the last 80 days , so older shipments may face a different process later.

What that means

  • Companies that had tariff bills finalized recently are the ones in the current refund window.
  • The government has been processing claims in phases, not as one universal deadline for every shipment.
  • Some outlets describe it as a “deadline this week,” but the exact date may depend on the specific shipment and filing category.

Practical takeaway

If you mean the current filing window , companies should treat it as urgent and file immediately for eligible entries. If you mean the broader legal refund fight, that is still evolving and older claims may be handled through a later mechanism.

TL;DR

The current refund window is now , with reports pointing to a deadline this week and an 80-day eligibility limit for the first phase.
