You paid at least 90% of the tax that appears on the tax year return or 100% of the tax that appears on the previous year's return, whichever is less. In general, taxpayers must make estimated tax payments in four equal amounts to avoid a penalty. However, if you receive income unevenly during the year, you can vary the payment amounts to avoid or reduce the penalty using the annualized fee method. Use Form 2210, Estimated Underpayment of Tax by Individuals, Estates and Trusts, to see if you owe a penalty for underpaying.
The first thing you can do is file a new Form W-4 to your employer with fewer deductions to cover your tax liability for the following year. However, there are times when someone may not have paid enough to pay taxes and find out during the filing season when it's too late. Then, review the IRS tax withholding estimator, print out the resulting W-4 forms, and review them quickly. The United States income tax system is a pay-per-use tax system, meaning that you must pay income tax as you earn or receive your income during the year.
You will incur an underpayment penalty if you pay less than 90% of your tax liability during the tax year.

If you didn't pay enough taxes during the year, either through withholding or through estimated tax payments, you may have to pay a penalty for paying less than the estimated taxes. Schedule AI will annualize your taxes at the end of each pay period based on your income, deductions and other items related to events that occurred from the beginning of the tax year to the end of the period.
After reviewing the estimator's instructions, it will show the expected tax withholding for the year, along with the estimated tax liability and underpayments, if any. Meanwhile, this is what happens when you underpay taxes, using the example of someone who submits quarterly estimated payments. If you are paid seasonally or have high and low months, the IRS suggests annualizing your income by adding what you earn in a year, dividing it by twelve and paying taxes according to the calculated monthly average. Or you can pay the same amount of last year's tax liability or 90 percent of current year's tax liability.
If you don't update your paycheck withholding to address the new situation, you may be left with a huge tax bill, plus some penalties, when April 15 arrives. You can eliminate or reduce your penalty if you don't receive your income evenly throughout the year.
