Yes, the IRS charges a failure-to-file penalty if you owe taxes and file late, usually 5% of the unpaid tax per month (up to 25%), plus a minimum penalty if more than 60 days late, and interest accrues on unpaid taxes; however, you can avoid penalties by filing for an extension (Form 4868) or if you're owed a refund, but be aware there's a separate failure-to-pay penalty if you don't pay on time, and you can seek relief for reasonable cause.
You might have to pay IRS penalties and interest if you file your federal income tax return after the April deadline, your due date isn't extended, and you end up with a tax bill. First, the IRS charges a 5% penalty per month on any tax due if your return is filed late. The penalty is capped at 25% of the tax owed.
Even though April 18 was the deadline to file tax returns and pay your taxes, you can still file tax returns even after that deadline. If you are going to owe on your return and you haven't paid yet, there will be interest and penalties but the sooner you file and pay, the less interest and penalty you will accrue.
The 'Failure to Lodge on Time' (FTL) Penalty
This penalty is not a flat fee; it is calculated using a system of 'penalty units' that increase every 28 days your return is overdue.
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.
If you can't pay your taxes by April 15, file your return anyway (even if you can't pay) to avoid the much steeper failure-to-file penalty, pay what you can, and then apply for an IRS payment plan (Installment Agreement) online for a short-term (up to 180 days) or long-term (monthly payments) plan, as penalties and daily compounded interest will accrue on the unpaid balance.
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.
If you have a balance owing, the CRA may charge interest and a late-filing penalty on returns filed after the due date. If you file your return after April 30, your GST/HST credit, climate action tax credit, Canada child benefit and B.C. family benefit, and Old Age Security benefit payments may be delayed.
The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
No, you generally cannot skip a year of filing taxes if you meet the IRS filing requirements (income thresholds, self-employment earnings, etc.), as it's a legal obligation that can lead to significant penalties and interest if you owe taxes, though you might not need to file if your income is below the standard deduction and you have no other filing triggers. It's always better to file a late tax return (even if you can't pay immediately) to avoid penalties, especially if you're owed a refund, which you can lose if you file more than three years late.
For individuals, the last day to file your 2025 taxes without an extension is April 15, 2026. You can submit Form 4868 to request an extension to file later during the year.
Sound reasons, if established, include:
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).
The law gives procrastinators three years to submit a return and claim a refund. The three-year countdown starts on the original due date of the return or the extension due date, if an extension was filed.
Most taxpayers will do anything they can to avoid tax audits. Filling out an accurate tax return is the best way to avoid an audit. Additionally, you should ensure you double-check your math and only claim legitimate tax deductions. E-filing may also be helpful.
There is no hard limit on how many years you can file back taxes. However, to be in “good standing” with the IRS, you should have filed tax returns for the last six years.
Yes! You can still file your taxes for 2025, but you may not be able to avoid penalties. If you're getting a tax refund, you won't have to worry about being charged any penalties or interest. If you owe taxes, the two penalties mentioned above may apply.
You can avoid a penalty by filing accurate returns, paying your tax by the due date, and furnishing any information returns timely.
If you didn't pay enough tax throughout the year, either through withholding or by making estimated tax payments, you may have to pay a penalty for underpayment of estimated tax.
For each month or part of a month that your tax return was late, the combined maximum penalty is 5% (4.5% late filing and 0.5% late payment), up to 25% of the unpaid tax at the time of filing. The late filing penalty applies to the tax that remains unpaid after the due date.
