If you’re self-employed, a landlord, or earn income from investments, you’re likely required to make quarterly estimated tax payments. These cover income tax and self-employment tax—and skipping them or miscalculating can lead to IRS penalties.
Who Needs to Pay?
This includes freelancers, gig workers, business owners, S corp shareholders, landlords, and investors. If you expect to owe $1,000 or more in taxes after credits and withholdings, estimated taxes apply.
Key Due Dates:
April 15: For income from Jan 1–Mar 31
June 15: For income from Apr 1–May 31 (June 16 in 2025)
September 15: For income from Jun 1–Aug 31
January 15 (following year): For income from Sep 1–Dec 31
How to Calculate
Estimate total annual income.
Subtract deductions (standard/itemized, retirement, etc.).
Apply federal tax rates.
Add self-employment tax (15.3% up to $176,100 in 2025).
Subtract credits/withholding.
Divide by four (or use the annualized method if income fluctuates).
Avoiding Penalties
You’re typically safe if you pay:
90% of this year’s tax, or
100% of last year’s tax (110% if AGI > $150k).
If you also have W-2 income, increasing paycheck withholding can reduce or eliminate your need to make estimated payments.
Smart Habits
Save 25–30% of net income for taxes.
Use software like QuickBooks or Xero.
Automate payments through IRS Direct Pay or EFTPS.
Staying compliant with estimated taxes doesn’t have to be stressful—especially with expert guidance.
