Interest on individual 2019 refunds reflected on returns filed by July 15, 2020 will generally be paid from April 15, 2020 until the date of the refund. Interest payments may be received separately from the refund. By law, the interest rate on both overpayment and underpayment of tax is adjusted quarterly. The interest rate for the second quarter, ending on June 30, 2020, is 5% per year, compounded daily. The interest rate for the third quarter, ending September 30, 2020, is 3% per year, compounded daily.

 

 

After the tax return has been Accepted by the IRS (meaning only that they received the return) it will be in the Processing mode until the tax refund has been Approved and then an Issue Date will be available on the IRS website.
