One of the most common surprises we see at tax time is taxpayers owing far more than expected because not enough taxes were paid in during the year.
This often leads to the question: "Do I need to make quarterly estimated tax payments?"
The answer is: Possibly — especially if you have income that does not have taxes automatically withheld.
What Are Quarterly Estimated Tax Payments?
Quarterly estimated tax payments are payments made directly to the IRS and state throughout the year to cover taxes on income that is not subject to withholding.
Common examples include:
- Self-employment income
- 1099 contractor income
- Side businesses
- Rental income
- Retirement income
- Pension income
- Investment income
- Capital gains
- IRA withdrawals

Why Do Some People Owe Taxes at the End of the Year?
Many taxpayers assume taxes are automatically being withheld from all income sources, but that is often not the case.
For example:
- Retirement accounts may have little or no withholding
- Pension withholding may not be enough
- 1099 income usually has no withholding at all
- Investment income generally does not have withholding
- Side business income may create self-employment tax
As a result, taxpayers sometimes owe large balances when filing their returns.
Who Commonly Needs Estimated Payments?
We frequently see estimated payment issues with:
- Retirees
- Self-employed individuals
- Independent contractors
- Small business owners
- Real estate investors
- Taxpayers with multiple income sources
Even taxpayers with W-2 jobs may need estimated payments if they also have side income or investment income.
What Happens If You Don't Make Estimated Payments?
If enough tax is not paid throughout the year, the IRS and Oregon may assess underpayment penalties and interest charges. This can happen even if the full balance is paid by the tax filing deadline.
Many taxpayers are surprised to learn that paying in April does not always eliminate penalties if taxes were underpaid during the year.

What Is the "Safe Harbor" Rule?
The IRS has "safe harbor" rules that may help taxpayers avoid underpayment penalties.
In general, many taxpayers can avoid penalties if they pay in:
- 100% of the prior year's total tax liability, or
- 110% for some higher-income taxpayers
Oregon has its own estimated payment rules as well. The correct amount depends on each taxpayer's individual situation.
Can You Increase Withholding Instead?
Sometimes taxpayers can avoid making estimated payments by increasing withholding from:
- W-2 wages
- Pensions
- IRA distributions
For retirees especially, increasing withholding from retirement income can sometimes be easier than remembering quarterly payments.
When Are Estimated Payments Due?
Estimated tax payments are generally due:
- April 15
- June 15
- September 15
- January 15 of the following year
If the due date falls on a weekend or holiday, the deadline may shift slightly.

Final Thoughts
Estimated taxes can be confusing, especially for retirees, self-employed taxpayers, and those with multiple income sources. A little planning during the year can often help avoid large balances due, penalties, interest charges, and tax-time surprises.
At Grants Pass Tax Service, we help Oregon taxpayers review withholding, calculate estimated payments, and plan ahead to help reduce surprises at tax time.
