Plain-language change summary

The updated version of SB 6347 changes the date concerning the estate tax adjustments from April 1, 2026, to July 1, 2026. This means that the new estate tax rules will take effect three months later than originally proposed. The shift in date could provide additional time for estates to plan for these changes, which might be significant for families and individuals managing inheritance matters.
