Tax Underpayment Penalty: What It Is, Examples, and How to Avoid One

OTR’s Integrated Tax System is now able to find all underpayments of estimated taxes and automatically charge penalties. For both federal and California state income taxes, you will use the last year’s tax return to determine how much to pay in estimated tax. Mistakes can be costly, with penalties and fees that can add up quickly. Understanding how to do the calculations, how to make your payments correctly, and what is required to stay compliant can save you from unpleasant surprises.

With the help of a quarterly tax calculator, you’ll easily have your estimated tax payments sorted out. As an example, let’s say you owed the IRS $15,000 in taxes last year and paid $14,000 in estimated taxes during the year. When you filed your 1040, you sent the IRS a check for $1,000 to pay the remaining tax liability.

Refunds

Both the failure to file penalty and the failure to pay penalty are charged for a full month, even if you pay the balance due before the month ends. When both the penalties apply to the same month, the failure to file penalty is decreased by the amount of the failure to pay penalty so that the maximum combined failure to file and failure to pay penalty is 5% for any month. Remember that these taxes change by the quarter, so keep a close eye on what the IRS is doing. If the rate changes, you need to take it into account so that you aren’t given a tax penalty.

• If you do not qualify for an exception, your underpayment computation will be based on 90% of the current year’s income tax liability or 100% of your liability for the preceding year, whichever is less.

• An estimated payment worksheet is available through your individual online services account to help you determine your estimated tax liability and how many payments you should make.

If your adjusted gross income for last year exceeded $150,000, you must pay the lesser of 110% of last year’s tax or 90% of this year’s tax. You can split each quarterly payment into smaller weekly, biweekly or monthly payments if you like, as long as you have paid the full amount by each quarterly due date. There are other types of income, however, which are also subject to tax. For this income, you need to estimate and pay the tax yourself.

You are responsible for paying any additional tax liability you may owe. Whether you file your tax return on time or request an extension, the IRS requires you to pay the tax due by the filing deadline. If you don’t pay what you owe by that date, the IRS charges a failure to pay penalty. To avoid a failure to file penalty, make sure you file your return by the due date even if you can’t pay the balance due.

If you want to avoid these penalties, make sure you pay estimated quarterly taxes on time and avoid underpayment.
