Running a business is challenging enough â taxes shouldnât add unnecessary stress.
If you earn income that isnât subject to withholding (think profits, dividends, rental income), quarterly estimated tax payments may be required to stay compliant and avoid costly penalties.
Letâs break down what you need to know.
â
Why Quarterly Estimates Matter
The IRS requires taxes to be paid as income is earned, not just at year-end.
If you owe more than $1,000 when you file, you could face penalties.
Smart quarterly planning helps you:
- Avoid penalties + interest
- Maintain steady cash flow
- Prevent tax-time surprises
â
Who Needs to Pay?
You may need to pay quarterly estimates if youâre:
- A business owner
- Self-employed / freelancer
- Earning rental or investment income
- Receiving income without withholding
Note: Many business owners must make estimated payments personally, even if their business pays tax.

Quarterly Due Dates
Estimated payments are typically due:
- April 15
- June 15
- September 15
- January 15
If a due date falls on a weekend or holiday, it moves to the next business day.

How to Estimate Your Taxes
Quarterly payments are based on your projected:
Many follow the âsafe harbor ruleâ â paying 100â110% of last yearâs tax bill. Fast-growing companies should check estimates throughout the year.

Tips to Avoid Penalties
- Meet with your accountant mid-year
- Build estimates into cash-flow planning
- Adjust payments if income changes
- Use safe-harbor rules to stay protected
