IRS CP59 Notice: A Guide for Non-Filers 
Most of us have to pay taxes to the IRS each year. Even when we don’t owe taxes, we usually need to still file a tax return to prove to the IRS that we don’t owe anything. As a result, the majority of working Americans have to file a tax return. But what happens if we don’t? Several things can happen, including the IRS sending out a CP59 Notice.
Key Takeaways: IRS CP59 Notice Guide
- ✔ Non-Filer Alert: The IRS issues a CP59 when they believe you have failed to file a required tax return.
- ✔ Response Form: Most responses require Form 15103 to explain why a return was not filed or to submit the missing return.
- ✔ Penalty Risk: Failure-to-file penalties accrue at 5% per month, which is significantly higher than failure-to-pay rates.
- ✔ Substitute Returns: Ignoring this notice may lead the IRS to file a Substitute for Return (SFR), often resulting in a higher tax bill.
- ✔ The 8-Week Rule: If you filed within the last 8 weeks, the notice may have crossed in the mail and can likely be disregarded.
