I was searching through Oregon state government website and found interactive tool which let us to calculate our Oregon State taxes before filing state tax return.
Below is the link to calculate the Oregon taxes by Oragon Government.
This is very simple functionality and gives an idea about the Tax return. If you have some addition and subtraction regarding your state taxes, you able to figure out the estimated amount as refund or due.
If you are filing your tax return online or by your own or using any software this tool helps you decide whether you created the right tax return or not.
[Generally this tool is based upon the Taxable Income and the filing status combination. So amount is calculated on above condition with reference to the State Tax rates or State Tax Table.]
