The IRS and the Oregon Department of Revenue both offer options to pay your balance due (Fed, Oregon and Tri-Met) and quarterly estimated payments electronically.
The IRS offers their Direct Pay service, to pay from your checking or savings account without processing fees. Unlike their EFTPS option, you don’t need to create an account or enroll in anything. Just go directly to the Direct Pay website and follow the instructions to make a payment on your account.
At the end of 2015, the Oregon Department of Revenue overhauled their website. You can now instantly create an account through their Revenue Online system and set up payments for current year and prior year balances due, Tri-Met payments, quarterly estimated payments and more. You can also view information about past payments, account balances, letters sent to you and more.
The City of Portland still continues to offer the option to pay your Combined Portland/Multnomah Business License Tax balance due on their website. You must create an account to use their online option.
