Business & Occupation (B&O) Taxes

COVID-19 relief

The City wants to provide those who do business in Olympia with tax relief during this most difficult time and to encourage you to continue to do business as we recover from the COVID-19 pandemic.

The Olympia City Council has changed the due date for 2020 first quarter B&O taxes from April 30, 2020 to July 31, 2020 with no late filing penalties or interest on any 2020 first quarter B&O taxes.

This means you have until July 31, 2020 to file both your 2020 first quarter and second quarter B&O taxes. Please note that late filing penalties for first and second quarter B&O taxes will apply if the filings are not received by July 31, 2020.
