REAL PROPERTY TRANSFER TAX Title 4, Chapter 4.20 of the Oakland Municipal Code (OMC) requires that whenever you change ownership of real property, and record that change with the County of Alameda, you must pay a City of Oakland REAL PROPERTY TRANSFER TAX (RPTT). (Note: Alameda County has its own transfer tax.) The City's tax rate is 1.5% of the consideration received (for example, money exchanged or debt forgiven). Alameda County collects this tax on the City's behalf, but will still record the document if the recording party or its agent, e.g., a title company, fails to pay the tax. However, if the tax remains unpaid 24 hours after recordation, the tax becomes delinquent and is subject to penalties and interest.
