States and counties vary in terms of the length of time a homeowner can be delinquent on property taxes. Some states give homeowners one to three years to redeem liens for unpaid taxes, according to The Nest.
Some counties begin legal action regarding delinquent taxes immediately. For example, the County of San Francisco attaches a 10 percent delinquency penalty to any unpaid taxes the day after they're due, and all delinquent properties become tax-defaulted on June 30 of every year, explains SFTreasurer.org.
All states can put liens on properties for delinquent property tax, All Law points out. After a given period of time, the state can take possession of the property and sell it.
