Thanks for asking your question! I'm sorry to hear about your tax issue and I'm going to try my best to help you understand or resolve it.
The IRS has three years from the date you file a return to release the return and or ask for additional information.
If they hold your return past April 15, it will start to draw interest and the IRS will pay you interest.
How much interest?
At the market interest rate
Right now, it is 3%
Do you need anything additional?
Anything I can do to expedite matters?
You can contact the Taxpayer Advocate
They are there for this purpose.
If you would, please rate my response as "excellent" so that I may receive credit for assisting you today
