What to do if you missed the April deadline or still owe back taxes

“I recently discovered that I owe back taxes (yikes), and now I’m scrambling to figure out what to do next.”

This post from a Redditor resonates with many small business owners when the April tax deadline passes, and they haven’t filed or paid.

Maybe you had too many responsibilities, your business hit a rough patch, or your finances spiraled after a tough year. Now the deadline has passed, and that growing tax bill is a constant weight on the back of your mind.

A full 23% of that came from underpayments and non-filers. That’s over $150 billion owed by people who either couldn’t pay in full or didn’t file at all. 

It’s a common story, but one with very real consequences. Some business owners freeze and fall further behind. While others find that taking action changes everything.

“I called [the IRS] and waited on hold for two hours. When the agent answered, they were very kind… she sympathized and was able to extend my tax payment out six months to give me time to finish back taxes, sell my house and set up a payment plan without taking any actions to garnish my wages or put a lien on my house.”

The truth is, inaction costs more than the debt itself. And whether you missed the tax deadline or have years of back taxes weighing on you, there are steps you can take right now to get ahead of it. In this blog, we will walk you through those steps. 

1. File your return as soon as possible, even if you can’t pay

It’s easy to put off filing when you know you can’t pay your full tax bill. In fact, 46% of self-employed taxpayers say filing their taxes causes more stress than actually paying them. But here’s the truth: delaying your return only makes things worse.

Why? Because the late-filing penalty is significantly higher than the penalty for not paying. The IRS charges 5% of your unpaid taxes every month your return is late, up to 25% of your total balance. In comparison, the late-payment penalty starts at just 0.5% per month. So, filing is a smart first move. It also shows the IRS that you’re taking responsibility and treating your tax obligations seriously, not ignoring them.

2. Pay whatever you can right now

If you can’t afford the full amount, that’s okay. Pay as much as you can toward your balance. Here’s why that matters:

  • The IRS calculates penalties and interest based on your unpaid balance, so even a partial payment reduces how much you owe over time.
  • Paying shows good faith and can help your case later if you apply for penalty relief or a payment plan.

You can pay directly on the IRS website using IRS Direct Pay, debit or credit card, or through a digital wallet. If you have already created an IRS Online Account, you can also view your balance and make payments there.

3. Explore payment plan options

If you’re staring at a tax bill that feels too big to tackle all at once, don’t panic; there are ways to break it down. The IRS payment plan lets you pay off your balance over time, and for many small business owners, this can offer the breathing room they need to stay compliant without derailing cash flow.

There are two main types of payment plans, and which one you qualify for depends on how much you owe. 

  • Short-term payment plan: If your total tax debt (including penalties and interest) is under $100,000, you may be eligible for a short-term payment plan. This gives you up to 180 days to pay off the balance. There’s no setup fee for this option, but interest and penalties will continue to accrue during the repayment period. Still, it’s a practical way to avoid falling further behind while staying on the IRS’s good side.
  • Long-term payment plan: For debts under $50,000, a long-term payment plan, also known as an installment agreement, might be the better fit. This option spreads your payments out monthly, usually through automatic direct debit. There is a setup fee involved, although the IRS may reduce or waive this fee for low-income taxpayers. 

One benefit of entering a formal installment agreement is that the IRS lowers the penalty rate for late payments while you’re actively paying under the plan. Instead of the standard penalty of up to 1% per month, it’s capped at 0.25%, which can make a noticeable difference over time.

Applying for these plans is easier than most people expect. You can do it online, and in many cases, you’ll get an immediate response. It’s worth considering if you need a structured way to file back taxes without resorting to drastic measures.

4. Check if you qualify for penalty relief

If this is your first time dealing with a missed tax deadline, you may be eligible for First-Time Penalty Abatement. This is the IRS’s way of giving compliant taxpayers a break.

To qualify, you must:

  • Have filed and paid on time for the past three years
  • Not have any previous penalties (or have reasonable cause for them)

Alternatively, you might qualify for reasonable cause relief if something out of your control caused the delay, such as a serious illness, natural disaster, or financial hardship. Either way, if you’re applying for relief, be ready to provide documentation.

5. Consider an Offer In Compromise (OIC)

If your tax bill is more than you can reasonably pay, even with a payment plan, there’s still a possible path forward. The IRS offers something called an Offer in Compromise (OIC), which lets you settle your tax debt for less than the full amount you owe.

In fiscal year 2023, taxpayers submitted over 30,000 Offers in Compromise to settle their tax debts for less than the full amount owed. The IRS accepted nearly 13,000 of these offers, resulting in a total reduction of $214.5 million in tax liabilities. This shows that while qualifying for an OIC can be challenging, it remains a valuable option for many struggling with their tax debt.

The IRS will look at your financial statements, income, expenses, cash flow, asset equity, and future earning potential. If they determine that you truly can’t pay the full amount without serious financial hardship, they may accept your offer. 

But be prepared, this process is paperwork-heavy and takes time. You’ll need to complete IRS Form 433-B for businesses and submit documentation like bank statements, pay stubs, mortgage records, and proof of living expenses.

It’s not a guaranteed option, but for some taxpayers, it’s the only realistic way to pay and file back taxes without going deeper into financial distress. 

The bottom line 

One missed tax deadline or overdue tax payment won’t destroy your business. But if it keeps happening, it can snowball into bigger problems: mounting penalties, limited cash flow, and long-term financial strain.

The best way to prevent these problems is accurate bookkeeping. When your books are kept up to date, you can stay on top of estimated tax payments, prepare filings without the last-minute chaos, and plan ahead instead of panicking.

However, proper bookkeeping requires expertise and dedicated time, two things you might not have as a business owner.

That’s why outsourcing is the best option for growing businesses that need expert oversight but can’t afford an in-house team.

We maintain accurate and timely records of your income and expenses, track your cash flow, and help you set aside the right amounts for estimated tax payments. This means your books are always ready for tax season, reducing the risk of missing deadlines or surprises from unexpected tax bills.

FAQs

What happens if I ignore my IRS tax debt completely?

Ignoring your tax bill can lead to serious consequences like wage garnishment, liens on property, and eventually asset seizures. The IRS will pursue collection aggressively if no action is taken.

Can I still get a refund if I file my taxes late?

Yes, if you’re due a refund, you won’t face penalties for filing late. But you have a three-year window to claim it. After that, the IRS keeps your money.

Can back taxes affect my ability to get a business loan or credit?

Absolutely. Tax debt can show up on your credit report or through public records if a lien is placed, which can negatively impact your ability to secure funding.
