Filing a tax extension does not increase your audit risk and may actually decrease it. Extensions provide more time for accuracy, allowing you to avoid rushed errors, incorporate late-arriving tax forms (like K-1s), and reduce the likelihood of needing to file an amended return. The IRS encourages extensions for complex returns.
An extension gives you extra time to file, but not extra time to pay. After you file an extension, if you owe taxes when you file your return, you might also have to pay penalties and interest on the tax due.
For those who are terrified of extensions, remember that they're okay. Unless you file for extensions for years and years, they're not going to increase your chance of being audited, and they won't have any consequences if you pay your taxes on time.
Filing a tax extension is not a bad thing. There is no penalty for filing a tax extension.
Top IRS audit triggers
This is simply not true. Filing an extension does not increase your audit risk in any way. While the IRS doesn't disclose exactly what triggers an audit, as experienced CPAs, we do see certain patterns.
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.
Your taxes don't affect your credit scores in any way. However, taking out a loan or credit card to pay your taxes can impact your credit scores.
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.
The CBDT's extension of the tax audit due date to October 31, 2025, provides a welcome relief for taxpayers and professionals. However, it is essential to utilise this additional time effectively to avoid penalties under Section 271B.
If you use software to file an extension online, you'll get confirmation that your extension was accepted. The IRS does not confirm extension requests sent by U.S. mail or an authorized private delivery service. But they will notify you if they deny your extension.
Common reasons for requesting an extension include a lack of organization, unanticipated events or tax planning purposes. Even if you obtain an extension to file, you must still pay your income tax in full by the tax deadline.
October 15 is the deadline for most U.S. individual taxpayers who requested an extension by the regular April deadline (usually April 15) to file their tax return. Think of it this way: the April deadline is for everyone. The October deadline is specifically for those who asked for and were granted extra time.
If you filed for online extension with Form 4868, you should have received an online confirmation number to confirm extension for your records.
The due date to file your California state tax return and pay any balance due is April 15, 2026. However, California grants an automatic extension until October 15, 2026 to file your return, although your payment is still due by April 15, 2026. No application is required for an extension to file.
You may request up to an additional 6 months to file your U.S. individual income tax return. There are three ways to request an automatic extension of time to file your return. You must request the extension of time to file by the due date of your return to avoid the penalty for filing late.
In this rush, the option to file for a tax extension is often seen as a last resort, the taxpayer has a lingering concern that it might raise red flags with the IRS or cause future tax problems. However, these worries are largely unfounded.
Many people worry about IRS audits. But the chances of being audited are actually very low for most individuals. Recent IRS data shows the IRS examined 0.40% of individual returns filed and 0.66% of corporation returns filed. Most of the IRS's focus is on large businesses and high-income earners.
Audit rates are generally highest for high-income taxpayers, taxpayers with business income, large corporations, and earned income tax credit claimants.
Objectivity is the cornerstone of the internal audit golden rule. Auditors must approach their work without bias, ensuring their evaluations are fair, impartial, and based solely on evidence.
There are five potential threats to auditor independence: self-interest, self-review, advocacy, familiarity, and intimidation. Any lack of independence compromises the integrity of financial markets.
