The Internal Revenue Service generally pays interest on refunds that are delayed by more than 45 days after the filing deadline, according to its website.
Which means 45 days after 4/15 not from when you filed.

When does the IRS pay Interest?
Stop and Start Dates for Overpayment Interest
In general, we pay interest on the amount you overpay starting from the later of the:
- Tax return filing due date
- Late filed tax return received date
- Date we get your return in a format we can process
- Date the payment was made
We stop paying interest on overpayments on the date we refund your overpayment (and interest) or offset it to an outstanding liability.
Exception: We have administrative time (typically 45 days) to issue your refund without paying interest on it.
How to Dispute Insufficient Interest Paid
If you think we underpaid interest owed to you on refunds or credits you're eligible for, you can file an informal claim or complete and send Form 843PDF for us to consider allowing additional overpayment interest. Make sure to include your own computation and reason for making the request for additional interest on Line 7 (see Instructions for Form 843).
Your request must be received within six years of the date of the scheduled overpayment.
