The IRS may waive penalties for a late tax return if the failure to file on time was due to a reasonable cause and not willful neglect. Acceptable reasons typically involve circumstances beyond your control, for which you must be prepared to provide supporting documentation.
The IRS will look at these factors:
Death, serious illness, or unavoidable absence. Fire, casualty, natural disaster, or other disturbance. Inability to obtain records. Mistake was made.
You may qualify for penalty relief if you demonstrate that you exercised ordinary care and prudence and were nevertheless unable to file your return or pay your taxes on time. Examples of valid reasons for failing to file or pay on time may include: Fires, natural disasters or civil disturbances.
a fire, flood or theft prevented you from completing your tax return. postal delays that you could not have predicted. delays related to a disability or mental illness you have.
Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit. The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.
Businesses that show losses are more likely to be audited, especially if the losses are recurring. The IRS might suspect that you must be making more money than you're reporting. Otherwise, why would you stay in business? Most likely to be audited are taxpayers reporting small business losses.
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.
Believable excuses are short, specific, and unavoidable, often involving sudden illness (like food poisoning, migraine, or flu), family emergencies (sick child, elderly parent), or home/transportation issues (burst pipe, car trouble), as these are beyond your control and usually require honesty without oversharing details. Keep it brief, mention you'll update them, and avoid over-explaining or using common lies that get caught.
Although there is no time limit for debt recovery, HMRC can't randomly investigate through decades worth of tax returns for any company on a whim. They need to have a genuine reason for investigating, and they must begin an enquiry no more than 12 months after the date a tax return was filed.
Common examples of reasonable cause include death or serious illness of the taxpayer or an immediate family member, natural disasters, and reliance on a tax professional.
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 file your return more than 6 months after the due date and you owe tax, your return will be subject to a late filing penalty.
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. If the return is more than 60 days late, the minimum late-filing penalty for returns due in 2026 is $525 or 100% of the tax owed, whichever is less.
The IRS can waive penalties if you demonstrate that your failure to comply with tax requirements was due to reasonable cause. Acceptable reasons include serious illness, natural disasters, or other events beyond your control that prevented timely tax filing or payment.
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.
You can use "legitimate excuse" to introduce a reason that is considered valid or acceptable. For example, "Being stuck in traffic is a "legitimate excuse" for being late to work." What's a less formal way to say "legitimate excuse"? Informally, you could say "good reason" or "valid explanation".
Lawful cause refers to a legitimate, legally recognized, and justifiable reason for taking a particular action or making a specific decision. It signifies that the action is based on a valid ground that complies with legal requirements, rather than being arbitrary, discriminatory, or without proper justification.
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.
If you're not eligible for First Time Abate penalty relief, the IRS may abate your penalties for filing and paying late if you can show reasonable cause and that the failure wasn't due to willful neglect.
The IRS $600 rule refers to a change in reporting requirements for third-party payment apps (like Venmo, PayPal) for taxable income from goods and services, where platforms must send a Form 1099-K if you receive over $600 in a year, intended to capture gig economy/side hustle income, though delays and phased implementation have adjusted the timeline, with current rules for 2024 using a higher threshold ($5,000) before fully phasing to $600 for future years, but remember all taxable income, regardless of form, must always be reported.
What Not to Say During an Audit?
The IRS escalates its collection efforts when the amount owed exceeds $25,000, which can result in severe penalties such as asset seizure, bank levy, wage garnishment, and even passport revocation. If you're unsure how much you owe, you can find more information and guidance here.
