If the IRS discovers you lied on your taxes, you face severe consequences, including hefty civil penalties (75% of the underpayment for fraud), interest charges, potential audits of multiple tax years, loss of future credits, and, in severe cases, criminal prosecution leading to fines up to $100,000 and jail time.
You will have to provide documentation to the IRS so they can determine if you lied, misrepresented your income, or otherwise incorrectly paid your taxes. In some cases, an audit will include in-person interviews. Lying to the IRS in an audit is a crime. An audit can be a lengthy, expensive, and exhausting process.
Tax evasion in California is punishable by up to one year in county jail or state prison, as well as fines of up to $20,000. The state can also require you to pay your back taxes, and it will place a lien on your property as a security until you pay taxes.
In many cases, the IRS will make the correction themselves and notify you of the change. If the error cannot be corrected by the IRS, you will be notified to make the correction yourself. Of course, any error can lead to a delay.
Avoid These Common Tax Mistakes
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.
Notices – The IRS will start sending you notices a month or two after you miss a tax deadline. Penalties and interest – If you don't respond to notices for missed tax payments, you'll continue to accrue penalties and interest.
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.
The overall odds of an IRS audit are low, about 4 out of every 1,000 returns. However, high-net-worth individuals are more likely to be targeted due to complex income sources, large deductions, and sophisticated financial structures.
The Truth About IRS “Forgiveness”
However—and this is important—the IRS does offer legitimate programs that can help struggling taxpayers resolve their debt, sometimes for significantly less than what they owe. These aren't new “forgiveness” programs created by any particular administration.
Potential Penalties
Imprisonment: A conviction can result in imprisonment for up to one year in county jail for misdemeanor tax evasion or up to three years in state prison for felony tax evasion. Fines: A fine of up to $20,000 for individuals and up to $100,000 for corporations.
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.
You can be charged penalties and interest on your IRS tax debt until you pay it off. The failure to pay penalty starts at 0.5% of your unpaid balance due per month (capped at 25% of the back taxes you owe). The 2025 interest rate for late payment of taxes is 7% but can change quarterly.
The IRS 3-year rule generally refers to the statute of limitations for claiming a tax refund, which is typically 3 years from when you filed your original return or 2 years from when you paid the tax, whichever is later, for the IRS to process your claim. For an audit, the IRS generally has 3 years from the date your return was filed or due (whichever is later) to assess additional tax, though this can extend to 6 years if you significantly underreport income or omit foreign income.
Remember, you will be contacted initially by mail. The IRS will provide all contact information and instructions in the letter you receive. If we conduct your audit by mail, our letter will request additional information about certain items shown on the tax return such as income, expenses, and itemized deductions.
The IRS gives you options for paying back taxes, including a short-term plan (up to 180 days) with no fee but accruing interest/penalties, or a long-term installment agreement (up to 10 years) for monthly payments, which usually has setup fees and less penalty rates if you filed on time. You can apply online at IRS.gov/paymentplan for amounts under certain thresholds (e.g., <$100k for short-term, <$50k for long-term), or by mail/phone if needed.
To be eligible, you must meet a few specific requirements. One is that you must be current with all your tax filing requirements. This means you can't have any unfiled tax returns. The IRS won't even consider tax forgiveness if you haven't filed all required returns for previous years.
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. For example, a valuation overstatement can result in a 30% penalty on the amount of tax owed.
The IRS does not check every tax return. It does not check the majority of them, but the IRS implements methods that track certain factors that would result in a further examination or audit by them.
