The Internal Revenue Service has issued new guidance on estimated tax payments for the 2025 tax year, raising standard deductions, updating credits, and confirming the quarterly payments schedule. The changes affect millions of Americans—including self-employed people, retirees, and independent contractors—who must pay estimated taxes on income not covered by federal income tax withholding.

Estimated Taxes and Who Must Pay

The IRS requires estimated taxes when income is not automatically withheld. This applies to earnings from freelance work, investments, rental property, and business income from independent contractors or corporation shareholders. Many self-employed taxpayers must make estimated quarterly tax payments to keep up with their tax liability.

According to the IRS, taxpayers must pay estimated amounts if they expect to owe at least $1,000 after subtracting withholding and refundable credits. Those who do not pay enough tax during each payment period may face an estimated tax penalty. The rules cover various income sources, from side jobs to capital gains. Even retirees with distributions from pensions or investments often must make estimated contributions to meet their federal tax obligations.

2025 Updates to Deductions and Credits

For the 2025 tax year, the IRS increased standard deductions, which lowers overall taxable income and may reduce the need to make quarterly estimated tax contributions. Single filers and married individuals filing separately can now claim $15,000, while married couples filing jointly receive $30,000. Heads of household are eligible for $22,500.

Several credits also rose. The maximum additional child tax credit increased to $1,700 per qualifying child, while the adoption credit rose to $17,280. These changes directly affect estimated payments, since credits reduce total tax owed on a federal tax return.

The Internal Revenue Service also updated the Social Security wage base to $176,100, affecting self-employed people who calculate payroll-related tax payments. To avoid surprises when filing, taxpayers are urged to review IRS worksheets and confirm how much tax they owe using an official IRS form or online estimator.

2025 Payment Schedule and Due Dates

The IRS confirmed that the due date for the first quarterly payment in 2025 is April 15, unless it falls on a legal holiday. Additional quarterly estimated tax payments are scheduled for June 16, September 15, and January 15, 2026. Taxpayers can skip the final quarterly payment if they file a timely federal tax return by February 2, 2026, and pay any balance in full.

Those who pay estimated taxes must follow the official tax deadlines to avoid penalties. The IRS warns that missing a quarterly payment or making unequal payments could lead to an underpayment penalty, unless reasonable cause is shown.

Payments may be made electronically through federal tax systems, such as Direct Pay and EFTPS, accessed on a mobile device, or by mailing a payment voucher.

Safe Harbor Rules and Penalties

The IRS maintains safe harbor provisions to help taxpayers avoid penalties when making estimated payments. Individuals can meet the requirement by paying either 90% of the current year’s total tax or 100% of the tax shown on the prior year’s income tax return. For higher earners with an adjusted gross income above $150,000, the threshold rises to 110%.

Failure to pay enough tax during the year can result in an estimated tax penalty. The agency notes that missing a due date, making unequal payments, or failing to follow all the rules may lead to an underpayment penalty, unless the shortfall was due to other unusual circumstances, reasonable cause, or not willful neglect.

Special rules apply to farmers, fishers, and certain resident alien taxpayers, who may qualify for simplified reporting instead of standard quarterly estimated taxes.

Guidance for Taxpayers

The IRS urges taxpayers to review their federal tax situation early to prevent a surprise tax bill. Those who need to make estimated contributions—such as self-employed people, retirees, and independent contractors—should calculate their obligations carefully and ensure they pay enough tax each period. Official worksheets in IRS Form 1040-ES or the online Tax Withholding Estimator help determine how much tax to set aside.

Taxpayers can make quarterly estimated tax payments online through the Electronic Federal Tax Payment System (EFTPS) or by mailing a payment voucher. Each option requires attention to the payment period and IRS due date, as outlined in the IRS newsroom updates.

The IRS also reminds households, including household employers, that meeting payment schedules protects against penalties. To stay compliant, taxpayers should track taxes, credits, and refundable credits and file a timely federal tax return to close out the year securely.
