Penalties begin immediately after tax day if you fail to file a return or pay what you owe. Requesting an extension before tax day can give you more time to file, but you’re still required to pay what you owe by April 15.

Although Minnesota and the IRS don’t process every return immediately on tax day, they will backdate interest and penalties to April 15.

What Happens After You Miss the Tax Deadline

1. April 15: Penalties and interest begin immediately. If you do not file, a failure-to-file penalty starts accruing. If you file but do not pay, failure-to-pay penalties and interest begin adding up on the unpaid balance.
2. Within a few weeks: Returns are not always processed right away, so you may not receive any notice immediately.
3. 3–8 weeks later: You will typically receive your first notice from the Internal Revenue Service or the Minnesota Department of Revenue. This notice outlines what you owe, including penalties and interest.
4. 1–3 months after the first notice: If the balance remains unpaid, follow-up notices are sent with updated totals and more urgent language about resolving the debt.
5. Several months after initial notices: A final notice may be issued warning of potential enforcement actions, such as levies. This typically includes a limited window to respond before further action is taken.
6. After the final notice period: If the issue remains unresolved, the account can move into enforced collections. At this stage, tax liens may be filed and levies against bank accounts or wages can occur.
7. Ongoing: Penalties and interest continue to accrue until the balance is resolved. Payment plans may still be available, but options can become more limited once enforcement actions begin.

Failure to File vs. Failure to Pay

Not filing and not paying are treated differently, but both lead to penalties.

Failure to file typically results in higher penalties, calculated as a percentage of the unpaid tax. Failure-to-pay penalties accrue at a lower rate, but interest continues building in either case.

Over time, even a relatively small balance can become expensive.

Failure to File or Pay Penalties Are Different From Audits

An audit is typically about whether the information on your tax return is accurate. That usually involves questions about income, deductions or credits.

Failing to file or pay is a different issue. In those situations, the government is not reviewing your return for accuracy. Instead, it is focused on collecting what it believes you owe.

Even if you do not file, the Internal Revenue Service can still estimate your income based on forms it receives from employers, banks or other sources. That estimate becomes the basis for penalties and collection efforts.

If you file but do not pay, the process is even more straightforward. The balance is already established, and collection efforts can begin after notice periods.

Enforced Collections and Resolution Options

Tax Liens and Levies

A tax lien is a legal claim against your property for unpaid taxes. It can attach to real estate, vehicles and other assets you own, which can make it more difficult to sell property, refinance or use those assets as collateral.

A levy goes further. It allows the government to take funds directly, such as freezing a bank account or garnishing wages.

Both the IRS and Minnesota have the authority to use these tools, but usually only after multiple notices have gone unanswered.

Payment Plans and Resolution Options

Both the Internal Revenue Service and the Minnesota Department of Revenue offer installment agreements that allow you to pay your balance over time.

Entering into a payment plan is often one of the most effective ways to stabilize the situation. It can help stop further escalation and give you a clear path to resolving the balance over time.

While penalties and interest may still apply, having an agreement in place allows you to avoid more serious collection actions as long as you stay current on payments. Without a plan, the balance can continue to grow and enforcement efforts may continue to escalate.
