In Montgomery County the Appraisal District does not collect taxes.
Current taxes are due when the statement is received by the property owner.
Property owners usually have until January 31 to pay their taxes without penalty. Under some circumstances, this deadline may be extended. Failure to receive a tax bill does not eliminate the taxpayer's responsibility to pay their taxes on time. Generally tax bills are mailed by October 1 of each year. Taxing jurisdictions may send tax bills at anytime when the appraisal district notifies the jurisdiction of a change that has affected the tax liability.
