- Tax bills are mailed by Dec. 1. Tax payments are due Dec. 31.
- If paying the tax bill in full is a financial burden, taxpayers have the option to make a partial payment before Dec. 31 to reduce the overall amount of statutory late payment interest and penalties. The Collector of Revenue also accepts advance payments for future bills.
- For convenience, real estate and personal property tax bills are combined into one statement in one envelope. Taxpayers should note, however, that they still could receive tax bills in separate envelopes if there are different names and addresses on their personal property assessment forms and real estate deeds. To prevent this in the future, residents should make certain the name and address on their personal property assessment forms and real estate deeds match. Personal property assessment forms are mailed by the Assessor at the end of January.
- Assets listed on personal property tax bills should include everything owned on Jan. 1 of the tax year, regardless of length of residency or ownership. If items listed are incorrect, contact the Assessor at 636-949-7420 or email@example.com.
- Revised statements are issued by the Collector’s office when changes are made to tax accounts after the original billing. These changes may be initiated by the taxpayer, the Assessor, the state tax commission, or a Special Assessment District. If an expected revised bill does not arrive by Dec. 15, please look for the new amount due online at StCharlesMoCollector.org or call the Collector’s office at 636-949-7470. Payment on revised statements, regardless of when or if it is received, is still due on Dec. 31.
- All real estate owners should receive a real estate tax bill(s). In addition to the owner of the real estate parcel(s) receiving bill(s), taxing services and mortgage companies receive an Electronic Bill File from the Collector of Revenue for use in paying from escrow accounts. Payment of the full tax amount is the responsibility of the current owner of the real estate (personally or from their escrow account).
- Payments for taxes received on or after Jan. 1 need to include late payment penalties and interest listed on the bill.
- Failure to receive a bill does not relieve the taxpayer of any tax liability imposed by state law. Taxpayers who have not received a bill by Dec. 15 are highly encouraged to look for the amount due online.
