Quick Primer (official): Comptroller of Maryland — Form MET-1 & Instructions (who must file, 9-month due date, Maryland DSUE, QTIP election on Schedule D). See also the Comptroller’s “What you need to know about Maryland’s estate tax” tip sheet. :contentReference[oaicite:1]{index=1}
Why this matters. Since 2019 Maryland uses a fixed $5,000,000 exclusion (not indexed). Maryland permits a state portability (DSUE) election on a timely filed MET-1; couples can preserve the first spouse’s unused Maryland exclusion. :contentReference[oaicite:2]{index=2}

Maryland Inheritance & Probate Basics

Estate vs. inheritance tax

Maryland imposes both: a state estate tax (Comptroller) and a separate inheritance tax (Registers of Wills). Inheritance tax is generally 10% for non-exempt transferees; many close-family transfers are exempt. :contentReference[oaicite:3]{index=3}

When due

Maryland estate tax return is due 9 months after death; extension to file does not extend time to pay. File directly with the Comptroller and attach federal schedules. :contentReference[oaicite:4]{index=4}

Planning Ideas to Reduce Maryland Estate Tax

  • Portability (DSUE). Preserve unused Maryland exclusion on a timely MET-1 to protect the survivor’s estate. :contentReference[oaicite:21]{index=21}
  • Maryland-only QTIP. Elect on MET-1 (Schedule D) to defer Maryland tax at the first death even without a federal QTIP. :contentReference[oaicite:22]{index=22}
  • Credit shelter trust. State-sized bypass trust remains useful given the fixed $5M exclusion and potential inheritance-tax offsets. (See local guidance.) :contentReference[oaicite:23]{index=23}
  • Liquidity & timing. Stage cash for the 9-month payment; filing and payment extensions are separate and interest may apply. :contentReference[oaicite:24]{index=24}
