IRS Form 2210: Underpayment of Estimated Tax by Individuals, Estates, and Trusts. This is a useful topic for self-employed workers, freelancers, investors, and taxpayers who may owe taxes because their paycheck withholding or estimated payments were too low. The IRS’s 2025 instructions explain that many taxpayers can let the IRS calculate the penalty, while certain situations require Form 2210 to be filed.

Many taxpayers believe that as long as they file their federal income tax return on time, they will not face an IRS penalty. However, the IRS may assess an underpayment penalty when taxpayers do not pay enough federal income tax throughout the year. This can affect self-employed individuals, independent contractors, retirees, investors, and others who do not have sufficient taxes withheld from their income.

IRS Form 2210, Underpayment of Estimated Tax by Individuals, Estates, and Trusts, helps determine whether a taxpayer owes an estimated tax underpayment penalty and, when required, calculates the amount. Understanding this form can help taxpayers plan ahead and avoid unnecessary tax costs.

What Is IRS Form 2210?

Form 2210 is used to determine whether an individual, estate, or trust paid enough federal income tax during the year through paycheck withholding, estimated tax payments, or other qualifying payments.

Federal income taxes generally operate on a pay-as-you-go system. This means taxpayers are expected to pay taxes as they earn income rather than waiting until they file their annual tax return.

For example, a Grand Rapids independent contractor may earn substantial income throughout the year but have no employer withholding federal income tax. If the contractor waits until filing season to pay the entire tax bill, an underpayment penalty may apply.

Form 2210 helps determine whether the taxpayer met the IRS payment requirements and whether a penalty is due.

Who May Need to Consider Form 2210?

Several types of taxpayers may need to review their estimated tax payments.

• Self-employed individuals: Business owners, freelancers, consultants, and gig workers may need to make quarterly estimated tax payments.
• Independent contractors: Individuals receiving Form 1099-NEC income generally do not have federal income tax withheld from those payments.
• Investors: Significant capital gains, dividends, interest, or other investment income may increase a taxpayer’s liability.
• Retirees: Pension payments, retirement distributions, Social Security benefits in certain circumstances, and investment income can affect withholding requirements.
• Landlords: Rental income may create additional tax obligations.
• High-income taxpayers: Higher income can affect the amount required to avoid an underpayment penalty.

Taxpayers who receive a large bonus, sell an investment at a substantial profit, or experience a sudden increase in business income may also need to review their payments.

How Much Tax Must You Pay to Avoid a Penalty?

The IRS generally requires taxpayers to pay at least the smaller of:

1. 90% of the tax for the current year, or
2. 100% of the tax shown on the previous year’s return, provided that the previous return covered a full 12-month period.

A higher prior-year payment threshold generally applies to taxpayers whose adjusted gross income exceeded $150,000, or $75,000 for married taxpayers filing separately. For these taxpayers, the prior-year percentage is generally 110%.

Special rules apply to certain farmers and fishers, and other exceptions may apply depending on the taxpayer’s circumstances.

These thresholds are commonly called safe harbors. Meeting an applicable safe harbor can help a taxpayer avoid the underpayment penalty even if the final tax bill is higher than expected.

However, calculating the required payment correctly is important. The rules can be affected by tax credits, withholding, filing status, prior-year tax liability, and other factors.

When Are Estimated Tax Payments Due?

Estimated tax payments are generally due in four installments during the year. The usual federal payment dates are April 15, June 15, September 15, and January 15 of the following year, with adjustments when a date falls on a weekend or legal holiday.

These installments do not always represent equal portions of a taxpayer’s actual income. For example, a self-employed person may earn very little early in the year but receive most of the annual income during the fall.

Missing an installment can potentially result in a penalty even if the taxpayer pays the full balance before filing the annual return. The IRS generally evaluates underpayments by installment period, not simply by looking at the final amount owed.

Taxpayers should keep records of estimated payments, including payment dates, amounts, and confirmation numbers.

Do All Taxpayers Have to File Form 2210?

No. This is an important distinction.

The IRS generally calculates the underpayment penalty for taxpayers who do not fall into certain categories requiring them to complete Form 2210. In those situations, the taxpayer can generally file the tax return without calculating the penalty and wait for the IRS to send a bill if a penalty applies.

Form 2210 may be required when a taxpayer must calculate the penalty under specific circumstances, uses certain methods to determine the penalty, or requests a qualifying penalty waiver.

The form’s instructions include a decision flowchart to help determine whether filing is required. Taxpayers should not assume that everyone who owes taxes must attach Form 2210.

Can You Reduce or Eliminate an Underpayment Penalty?

In some situations, yes.

Taxpayers with income that varies significantly during the year may benefit from the annualized income installment method. This method can help account for income earned unevenly throughout the year, such as seasonal business income or a large investment gain received late in the year.

Certain taxpayers may also qualify for a penalty waiver. The IRS may waive all or part of a penalty when an underpayment resulted from qualifying circumstances, such as retirement after reaching age 62 or disability during the relevant period, provided the applicable reasonable-cause requirements are met. Certain casualty, disaster, or unusual circumstances may also qualify under IRS rules.

A waiver is not automatic in every situation. Taxpayers may need to provide an explanation and supporting documentation, and the IRS determines whether the request qualifies.

Taxpayers affected by a federally declared disaster may also qualify for separate relief. The applicable disaster guidance should be reviewed before filing Form 2210 solely to request relief.
