Tax season can sometimes come with surprises -- and not always the good kind.

This article is not tax advice, please seek a tax professional for any tax assistance.

Each year many-a-breath is held as Americans file their taxes. Will the process end in a big tax refund? Or will an unexpected tax liability wipe out your bank account? Or maybe your situation will land somewhere in between.

Getting an income tax bill that is larger than you expected is far from a fun surprise, especially if you don’t have the cash to cover the amount you owe, but there may be payment options available. One possibility to consider is working out a payment plan with the Internal Revenue Service (IRS) so you can manage your tax debt through monthly payments.

Whether you have to deal with a big tax bill in the current year, are concerned about an unmanageable tax bill in the future, or you’re an installment agreement enthusiast, this is the article for you.

Clarify your tax payment obligations

No matter if you’re seeking for a solution to manage your tax situation or shopping for parachutes, the same principle applies: One size does not fit all.

“One's approach strategy depends on whether you actually owe the money or not,” explains Donna Merrill, business tax expert and founder of Business Untangled, Inc. However, she makes it clear that regardless of whether or not you think you owe the money, a tax due notice needs to be addressed in some way. If you ignore paying the balance due, the IRS could take collection actions against you by levying your bank account or garnishing your wages.

If you do believe there is an error in how your tax liability was calculated, Merrill recommends calling the IRS and explaining the issue as well as asking for an extension to properly address the situation.

Generally, however, Merrill recommends working with a tax professional if you can afford it, especially if you owe back taxes and face penalties.

IRS payment plans

Regardless of whether you decide to work with a tax attorney or other tax professional, an installment plan could be a good choice to deal with a larger tax bill.

“If you find yourself in a situation where you have a higher-than-expected tax bill, you can submit an installment agreement request with your tax return,” says Mike Savage, Founder and Chairman of 1-800Accountant.

What is an installment plan?

An installment plan allows you to divide the money you owe into regular, equal payments until you pay off your bill in full. However, taking advantage of this option with the IRS may still come with a penalty in terms of fees and interest. The cost of these extra charges can vary depending on your financial situation and your payment method.

Short-term payment options

You can apply for a short-term payment plan, which is an agreement that allows you to pay off your debt in less than 120 days.

Long-term payment options

Longer-term plans are also available, but will likely require a setup fee, depending on the specific plan. If you qualify as a low-income taxpayer, your setup fee may be waived. If you don’t qualify, your fee may range from $31-$225, depending on the method you use to submit your installment agreement request form.

Regardless of which plan you choose, you will still be accountable for any interest or penalties that the IRS charges during the installment agreement period. To learn more about these online payment agreements and what your personal requirements will be, visit IRS.gov or consult with a tax professional.

How do I fill out an Installment Agreement Request?

If you would like to pay off your tax liability with installment payments, fill out Form 9465, the Installment Agreement Request, when you file your return.

If the IRS approves your forms and you have provided the necessary financial information, you can set up a direct debit from your checking account. Payroll deduction is another payment method to consider if you prefer the IRS to deduct additional money from your paycheck to cover the payment amount. If that sounds appealing, check out IRS Form 2159.

If you need further financial assistance…

In some cases, unfortunately, even a payment plan may not be enough to overcome the tax burdens. The IRS offers the option to pursue an “offer in compromise” that lets low-income taxpayers settle their bill for less than the full amount. You can utilize the IRS’s prequalifier tool to determine if you are eligible for an offer in compromise.

Put it on the card?

Is it possible to put your tax bill on a credit card so you don’t have to worry about it until later?

Short answer: Yes. Long answer: Yes, but it might not be a great idea. You can learn more about that here.

There are additional fees associated with using a credit card, and if you are unable to pay off the bill in full by the end of the month, interest will begin accruing on your outstanding balance.

Plan for the next tax year

Ideally, you would like to avoid unpleasant surprises for future tax seasons. That means figuring out why your bill was so larger than expected and taking steps you can to make it more manageable in the future.

“Were your withholdings from your day job too low and you need to adjust your W-4 at work?” asks CPA Joshua Zirrili. “Did you have a side hustle that resulted in income with no taxes withheld? Once you determine that, you can correct it for next year so you don't wind up in the same situation during the next tax season.”

Use each tax bill as a learning opportunity. After all,  knowledge is half the battle.
