Estimated Tax Payments to the IRS: What & Why You Should Pay
What Are Estimated Taxes?
Estimated tax payments are quarterly payments made to the IRS on income that isn’t subject to withholding.
Typically, this includes self-employment income, rental income, interest, dividends, alimony, and gains from the sale of assets.
These payments are crucial for small business owners and individuals with significant non-wage income to avoid penalties.

Wage Withholding vs. Estimated Tax Payments
Understanding the difference between wage withholding and estimated tax payments is essential to effectively manage your tax responsibilities.
Wage Withholding Taxes
Wage withholding taxes are automatically deducted from your paycheck by your employer. This system ensures that your taxes are paid regularly throughout the year. Your employer calculates and withholds the appropriate federal, state, and sometimes local taxes from each paycheck based on your W-4 form.
Key Points:
- Automatic Deduction: Taxes are automatically withheld by your employer.
- Consistent Payments: Ensures regular payment of taxes throughout the year.
- Employee Responsibility: Employees must only ensure their W-4 form is accurately filled out to reflect their tax situation.
Estimated Tax Payments
On the other hand, estimated tax payments are made by individuals whose income is not subject to withholding, including self-employed individuals, freelancers, landlords, and investors. These quarterly payments ensure you cover your tax liability as you earn income.
Key Points:
- Self-Managed: Individuals are responsible for calculating and paying their estimated taxes.
- Quarterly Payments: Taxes are paid four times yearly based on estimated income.
- Non-Wage Income: This applies to income not subject to withholding, such as self-employment earnings, rental income, and investment gains.

Who Needs to Pay Estimated Taxes?
Estimated tax payments are required for:
- Self-Employed Individuals: If you own a business, freelance, or contract, you likely need to make estimated tax payments.
- Income Not Subject to Withholding: This includes dividends, interest, rental income, and alimony.
- Significant Additional Income: Consider estimated taxes if you receive substantial additional income not covered by withholding.
Specific Scenarios Requiring Estimated Taxes
- Freelancers and Contractors: Your income isn’t subject to withholding.
- Landlords: Rental income usually requires estimated tax payments.
- Investors: Substantial interest, dividends, or capital gains must be covered.

Calculating estimated taxes involves estimating your expected adjusted gross income, taxable income, deductions, and credits for the year.
Here’s a simplified process:
- Estimate Your Income: Include all sources of income.
