How does the IRS set its interest rate each quarter?
Under Section 6621 in the tax code, every rate follows the federal short-term rate. Individuals have one rate for both sides: what you pay in interest on tax you owe and interest on a late refund from the IRS. Interest compounds daily under Section 6622, so each day charges interest on the prior day’s balance plus the interest already on it.
A new rate never applies to earlier periods. An unpaid balance is charged each quarter at the rate that applies to that quarter. A plan balance is charged the same rate and the IRS payment plan interest rate page works it out for you.
- Individuals who owe and individuals owed a refund: 3 points on top of the federal short-term rate.
- A corporation’s refund: plus 2 points and half a point on any amount over $10,000.
- Corporations that owe more than $100,000: plus 5 points.
How much is IRS payment plan interest?
A payment plan carries the same rate. On a plan, the rate charged is the same 7% a year. If your filing was on time, a monthly late-payment penalty of 0.25% runs beside it. Use the IRS interest calculator to see the two amounts for your own balance. It applies this same rate.
