How to Calculate and Pay Estimated Taxes?

This article provides a detailed guide on how to calculate and make estimated tax payments for different entities, including individuals, businesses, trusts, and corporations. It offers practical advice and step-by-step instructions to help taxpayers meet their obligations efficiently.


Understanding and managing estimated tax payments is crucial for taxpayers who earn income not subject to withholding, such as earnings from self-employment, interest, dividends, and rental income. Estimated taxes are used to pay not only income tax, but also other taxes such as self-employment tax and alternative minimum tax. The process can be complex, with various requirements depending on the taxpayer’s entity type—individual, business, trust, or corporation. This comprehensive guide demystifies the formula for calculating estimated tax payments, outlines the methods available for making these payments, and provides specific guidance for different types of taxpayers, including businesses and special entities like trusts and S-corps. By adhering to the strategies and guidelines discussed, taxpayers can avoid penalties for underpayment and manage their tax obligations proactively throughout the year.

What is the Formula for Estimated Tax?

For Individuals: Estimated tax payments for individuals are generally calculated by projecting the annual tax liability, including income tax, self-employment tax, and any other taxes applicable. The basic formula is:

Estimated Tax= (Expected Adjusted Gross Income × Tax Rate)− Credits − Withholdings

Taxpayers need to consider their previous year’s tax liability, current year’s expected income, and any tax credits or deductions they anticipate claiming. Form 1040-ES, the Estimated Tax for Individuals, contains a worksheet to help calculate these payments.

For Businesses: Businesses, including corporations, partnerships, and S-corporations, estimate their taxes based on expected taxable income, current tax rates, and applicable credits. For corporations, the formula might look like this:

Estimated Corporate Tax= (Expected Taxable Income × Corporate Tax Rate) − Credits

Each type of business might have specific adjustments or credits applicable only to them.

How to Make Estimated Tax Payments?

For Individuals: Individuals can make estimated tax payments using IRS Form 1040-ES. Payments can be made online, by phone, or through mail. The IRS offers Direct Pay, the Electronic Federal Tax Payment System (EFTPS), and credit or debit options.

For Businesses: Businesses generally make their estimated tax payments through EFTPS. This system is designed to accommodate higher payment amounts and the more complex tax situations typical of businesses, including payroll taxes.

How Businesses Make Estimated Payments?

General Businesses: Most businesses are required to make quarterly estimated tax payments if they expect to owe tax of $1,000 or more when their return is filed. The use of EFTPS is mandatory for corporations with deposits of $10 million or more.

Partnerships and S-Corporations: While partnerships and S-corporations may pass income through to individual partners or shareholders, they may still need to make estimated tax payments for certain types of income or if they incur liabilities at the corporate level.

How to Make Estimated Tax Payments for a Trust?

Trusts typically make estimated tax payments if they expect to owe $1,000 or more in tax for the year. Form 1041-ES is used by fiduciaries to calculate and pay these estimated taxes. Payments are often submitted electronically via EFTPS.

How to Make Corporate Estimated Tax Payments?

Larger Corporations: Corporations are required to make payments that match their expected tax liability closely. The IRS mandates that they use EFTPS, and they may have additional reporting requirements, especially if their estimated taxes are substantial.

How to Make Estimated Tax Payments for an S-Corp?

S-corporations generally do not pay income taxes at the corporate level. Instead, income and losses are passed through to shareholders. However, if an S-corp owes excise taxes or certain other taxes, it must make estimated tax payments similarly to other business entities. Shareholders may need to adjust their personal estimated payments to account for their share of corporate income.

By following these guidelines, taxpayers from various entities can navigate the complexities of estimated taxes, ensuring compliance and avoiding underpayment penalties. This detailed examination of each category provides a clearer path for managing tax obligations effectively throughout the fiscal year.
