State Deed Tax (SDT)


  • The SDT is a state tax imposed on each deed or instrument by which any real property is granted, assigned, transferred or otherwise conveyed. The tax applies against the net consideration and the deed or instrument cannot be recorded until the deed tax is paid to the County Treasurer.
  • The SDT rate is 0.0033 of the net consideration. If there is no consideration or when the consideration is $500 or less, the minimum SDT due is $1.65.
  • Ninety-seven percent of the SDT is remitted to the State of Minnesota and 3% is retained by Washington County.
