State tax filing

@tbrown31349 

Those interest amounts can be assessed, even if you've paid over 90%.....and even if you get a refund !!!

The withholding probably wasn't the issue...it was probably the timing or amounts on your estimated tax payments.

IF you didn't pay those estimated taxes in even amounts for every quarter...or made larger payments in the last quarter or three....then, you would likely need to have prepared, and filed the OR-10 form along with your OR tax filing to get that interest (or interest and penalties) reduced or eliminated.

For instance, if you didn't make a 1Q estimated payment, or if you made a larger estimated tax payments in any of the last 3 Quarters to cover an unexpected bump in income...the default calculations can result in a penalty/interest because the default assumes all income was even over the year, and some of the taxes for it wasn't paid in the earlier quarters.

To possibly eliminate the penalty/interest, you would fill out the OR-10 form, which uses your annualized income (income by uneven "quarter"  3mos, 2mos, 3mos 4mos)  ) to let OR know exactly when your various sources of income occurred (interest, dividends, cap gains, pension income, wages etc), vs when your withholding and estimated payments occurred.

I don't have the TurboTax Oregon software...but for all the states I've seen, the TTX software does include the annualized income forms for that state in their state software, usually in the state Other Tax Situations page.  But TTX doesn't automatically force you thru those calculations, you usually have to start thru them yourself....why???  Because they are a pain-in-the-patootie to fill out, requiring you to gather tons of exacting information for the whole year.  Having done it once, I won't bother again for a penalty/interest less than ~$50...and would think long before doing it for less than ~$100.
