What this guide covers

  • For 2026 the estate/gift and GST exemptions are each $15,000,000, permanent under the OBBBA and indexed from 2027; top rate 40%.
  • The annual exclusion is $19,000 per donee ($38,000 with gift-splitting); 2503(e) tuition/medical payments are unlimited.
  • Portability captures DSUE but not the GST exemption and preserves a second step-up — weigh it against bypass-trust benefits.
  • Under a large exemption, income-tax basis step-up planning often matters more than transfer-tax reduction.
