Projected figures are estimates. For tax years after 2026 the Form 8938 and FBAR forms and instructions have not been published. This checker assumes the thresholds and filing dates in the current regulations and IRS guidance continue unchanged. If Treasury or FinCEN changes them, the result for those years will differ. Not tax advice.
