Late-filed tax returns generally take about 6 weeks to process once received by the IRS (https://www.irs.gov/businesses/small-businesses-self-employed/filing-past-due-tax-returns). While electronically filed, on-time returns are usually processed within 21 days, past-due, paper-filed, or returns with errors will take significantly longer, potentially stretching into months depending on IRS backlogs.
If you received a notice, you should send us a copy of the past due return to the indicated address. It takes approximately 6 weeks for us to process an accurately completed past due tax return.
If you're expecting a refund, there are no penalties or interest charges for filing late. However, filing late will delay your refund and extend the statute of limitations for audits.
If you file taxes after the October 15 extension deadline, the IRS will assess penalties and interest, primarily a failure-to-file penalty (5% per month, max 25%), plus a separate failure-to-pay penalty (0.5% per month) and daily interest on the unpaid taxes, though you can request penalty abatement for reasonable cause like natural disasters. The October deadline is for filing, not paying; if you owe, payment was due in April, so you'll likely face both penalties and interest until you file and pay, but you won't be penalized if you're due a refund.
If you owe tax and don't file on time (with extensions), there's also a penalty for not filing on time. The failure-to-file penalty is usually five percent of the tax owed for each month, or part of a month, that your return is late, up to a maximum of 25%.
Is there a penalty for filing taxes late? If you file your taxes late and owe money, the CRA charges you a penalty on the taxes owed. The first time you are late on your taxes, the CRA interest rate on your balance owing is 5%, plus an additional 1% percent for each month they're late—up to 12 months.
One-time forgiveness, officially known as First-Time Penalty Abatement (FTA), is an IRS program that allows qualified taxpayers to have certain penalties removed from their tax accounts.
But here's generally what you can expect. No penalty if you're getting a tax refund. However, you must file your 2025 taxes by April 15, 2029 (or October 15, 2029 if you filed an extension). After that, any unclaimed tax refund gets turned over to the US Treasury.
The IRS charges penalties for failing to file (usually 5% per month, max 25%) and failing to pay (0.5% per month, max 25%), plus interest, but both penalties are reduced if you're on an approved payment plan. A separate, higher penalty applies if you don't pay within 10 days of an IRS levy notice. Paying as much as possible by the deadline and setting up a payment plan are key to minimizing costs.
You can avoid a penalty by filing and paying your tax by the due date. If you can't do so, you can apply for an extension of time to file or a payment plan.
The IRS doesn't have a strict maximum time limit for issuing refunds, but generally processes e-filed returns with direct deposit within 21 days, while paper returns take 6 weeks or more, with longer waits for those claiming certain credits (EITC/ACTC) or if errors occur. If the IRS holds your refund for more than 45 days past the tax deadline (or filing date if late), they owe you interest, but significant delays (months) can happen for complex issues or extra reviews, sometimes requiring a mailed notice.
You might be thinking, “If I've already missed the deadline, what's a few more weeks?” But it's better to file (and pay) late than not at all. The sooner you submit your tax return, the better (we'll get to why in a moment). If you do miss the deadline, do your best to file the next day or soon thereafter.
When you file: If you file your federal tax return early in the season, you'll likely receive your tax refund sooner. However, if you wait to file your tax return close to the filing deadline, it may take longer to process because more returns are filed at this time.
There's no strict maximum limit for how long the IRS can hold a refund, but they must pay interest after 45 days; while most e-filed returns take 21 days, returns needing extra review for errors, fraud, or certain credits (like EITC/ACTC) can take months (45-180+ days), and amended returns can take 8-16 weeks, with unfiled returns having an indefinite delay until filed.
If you don't file your tax return by the October 15 extension deadline, the IRS charges a failure-to-file penalty of 5% per month (up to 25%) on unpaid taxes, plus a failure-to-pay penalty (0.5% per month), and interest on the total amount due, potentially leading to significant costs, though you can request penalty abatement for reasonable cause, and if you're owed a refund, you generally won't face penalties but risk losing your refund if you wait too long (usually over 3 years).
Individuals and most business tax returns
The penalty doesn't apply if you can show the failure was due to reasonable cause. The penalty is 5% of the tax due (less any tax paid on time and available credits) for each month or partial month the return is late. The penalty accrues up to a maximum of 25%.
We may be able to remove or reduce some penalties if you acted in good faith and can show reasonable cause for why you weren't able to meet your tax obligations. By law we cannot remove or reduce interest unless the penalty is removed or reduced. For more information, see penalty relief.
Interest will be charged on late payments after this date. If HMRC have asked you to complete a tax return for 2024/25, and you miss the deadline, you'll automatically be fined regardless of how small your tax liability is. A penalty will also apply if you are due a refund.

The IRS 7-year rule primarily applies to keeping records for claiming a deduction for bad debts or losses from worthless securities, allowing a longer period to file for a credit or refund, but it's not a universal audit limit; it's often a recommended safe buffer for general record-keeping, with the standard IRS audit period usually being 3 years, extending to 6 years for substantial income omission (over 25%) or foreign income issues, and indefinitely for fraud.
They can apply for a payment plan at IRS.gov/paymentplan. These plans can be either short- or long-term. Short-term payment plan – The payment period is 180 days or less, and the total amount owed is less than $100,000 in combined tax, penalties and interest.
This penalty of 20% or 40% of the increase in tax is due in the case of substantial understatement of tax, substantial valuation misstatements, transfer pricing adjustments, or negligence or disregard of rules or regulations.
