Taxpayers waiting for the IRS’s official Yearly Average Exchange Rates will need to hold on a little longer. As of now, the IRS has not yet published its annual table for the 2025 tax year.
However, there is some good news for those preparing FBARs (FinCEN Form 114) or other filings that rely on year‑end Treasury exchange rates. The U.S. Treasury has released its 31 December 2025 foreign currency rates, which are the mandated figures for FBAR reporting.
For New Zealand, the Treasury’s published rate is:
1 USD = 1.733 NZD (as of 31 December 2025)
This rate applies specifically to FBAR reporting and any other compliance requirements that reference the Treasury’s year‑end exchange table. Once the IRS releases its separate annual average rates for income‑tax purposes, taxpayers will be able to use those for Form 1040, 1040‑NR, and other IRS filings where annual averages are permitted. Please note that annual averages are not always permitted.
In the meantime, the Treasury’s 31 December 2025 figures provide a reliable benchmark for anyone preparing foreign account disclosures or beginning early tax‑year planning.
