An agency that coordinates the filing of municipal taxes around Ohio extended its filing deadline until Monday.
The Regional Income Tax Agency (RITA) says its website and phone system were overwhelmed with hits and calls from last minute filers.
Belpre is one of the communities it serves.
RITA says the problem is so many people waited until the last minute to file.
The tax agency said it experienced an "unprecedented demand" for online services, including the electronic filing of municipal income taxes in dozens of communities across Ohio.
