Filing an Extension Doesn’t Mean You’re Out of Options
Many people assume that once they file a tax extension, they don’t have to think about taxes again until October.
Unfortunately, that’s one of the biggest misconceptions about tax extensions.
An extension gives you more time to file your tax return, but it generally does not extend the deadline to pay any taxes you owe. If you paid less than your actual tax bill, the IRS may charge interest and, in some cases, penalties on the remaining balance.
The good news is that underpaying doesn’t mean you’ve run out of options.
At Starner Tax Group, we help individuals and business owners throughout Pea Ridge, Northwest Arkansas, and Southwest Missouri understand what happens next and how to resolve tax balances as efficiently as possible.
Why You May Still Owe Money
When you request a tax extension, you’re estimating what you expect to owe.
Sometimes that estimate ends up being lower than your final tax liability.
This can happen if:
- Income was higher than expected.
- Tax credits changed.
- Deductions were smaller than anticipated.
- Investment or self-employment income increased.
- Important tax documents arrived later.
Even careful estimates aren’t always perfect.
What Happens If You Underpaid?
If your payment was less than the amount actually owed, the IRS may assess:
- Interest on the unpaid balance
- Late payment penalties, depending on your situation
Interest generally begins accruing from the original tax payment deadline—not from the extension deadline.
The sooner the remaining balance is paid, the less additional interest will accumulate.
Don’t Ignore IRS Notices
If the IRS sends you a notice, open it as soon as possible.
Most notices explain:
- The amount owed
- Interest or penalties that have been added
- Payment options
- Deadlines for responding
Ignoring these notices can make resolving the issue more difficult.
Pay What You Can
If you’re unable to pay the full balance immediately, paying part of what you owe can still help.
Every payment reduces the remaining balance and may reduce the amount of future interest that continues to accrue.
Even partial payments are generally better than waiting until you can pay everything at once.
Payment Plans May Be Available
If paying the full balance would create a financial hardship, the IRS offers payment options for many taxpayers.
Depending on your circumstances, you may qualify for:
- Short-term payment arrangements
- Monthly installment agreements
- Other payment solutions
The best option depends on your financial situation and the amount owed.
When Should You Contact a Tax Professional?
Some tax situations are straightforward, while others become more complicated.
Professional guidance may be helpful if:
- You owe a significant balance.
- You’ve received multiple IRS notices.
- You’re unsure whether penalties were calculated correctly.
- You need help setting up a payment plan.
- You have tax issues from multiple years.
Getting advice early often provides more options than waiting until the problem grows.
Plan Ahead for Next Year
Once this year’s return is resolved, it’s a good time to look ahead.
Simple planning steps can help reduce the chance of another unexpected balance.
Consider:
- Reviewing your withholding.
- Updating estimated tax payments.
- Tracking self-employment income throughout the year.
- Scheduling a mid-year tax planning appointment.
- Meeting with your tax advisor before year-end.
Proactive planning is often the easiest way to avoid future surprises.
Frequently Asked Questions
Does a tax extension give me more time to pay?

What if I can’t pay everything I owe?
You may have payment options available through the IRS. A tax professional can help you understand which solution best fits your situation.
Should I ignore an IRS notice if I’m planning to pay later?
No. Review every IRS notice carefully and respond promptly if action is required.
