Paying in full within 120 days. A taxpayer can pay the full amount owed within 120 days, without having to pay any fee, but interest and any applicable penalties continue to accrue until the tax is paid in full. Taxpayers can use an online payment application.

Installment agreements. Taxpayers unable to pay the full amount owed within 120 days may be able to enter into an installment agreement with IRS to pay the tax. Apply using Form 9465, Installment Agreement Request, and Form 433-F, Collection Information Statement.

There are different rules for taxpayers who owe $10,000 or less, and for taxpayers who owe $50,000 or less.

Taxpayers are eligible for a guaranteed installment agreement if the aggregate amount of the liability (determined without regard to interest, penalties, additions to the tax, and additional amounts) is not more than $10,000 and:

• During the past five tax years, the taxpayer (and spouse if filing a joint return) have timely filed all income tax returns and paid any income tax due, and have not entered into an installment agreement for payment of income tax;
• The taxpayer agrees to pay the full amount owed within three years and to comply with all Code provisions while the agreement is in effect; and
• The taxpayer is financially unable to pay the liability in full when due and submits information that IRS may require to make this determination (i.e., a financial statement). (Code Sec. 6159(c)(2); Reg. § 301.6159-1(c)(1))

Under recently finalized regs, the following fees apply to installment agreements entered into on or after Jan. 1, 2017, except for low-income taxpayers:

• $225 for regular installment agreements, where a taxpayer contacts IRS in person, by phone, or by mail and sets up an agreement to make manual payments over a period of time either by mailing a check or electronically through the Electronic Federal Tax Payment System (EFTPS). (Reg. § 300.1(b))
• $107 for direct debit installment agreements, where a taxpayer contacts IRS by phone or mail and sets up an agreement to make automatic payments over a period of time through a direct debit from a bank account. (Reg. § 300.1(b)(1))
• $149 for online payment agreements, where a taxpayer sets up an installment agreement Online Payment Agreement application. (Reg. § 300.1(b)(2))
• $31 for direct debit online payment agreements, where a taxpayer sets up an installment agreement and agrees to make automatic payments over a period of time through a direct debit from a bank account. (Reg. § 300.1(b)(2))

The fee is $43 for certain qualifying low-income taxpayers, but is reduced to $31 when the taxpayer pays by way of a direct debit from the taxpayer's bank account with respect to online payment agreements. (Reg. § 300.1(b)(3))

Offer in compromise (OIC). An OIC is an agreement between a taxpayer and IRS that settles the taxpayer's tax liabilities for less than the full amount owed.

Taxpayers who the IRS believes can fully pay the liabilities through an installment agreement or other means,

To qualify for an OIC, the taxpayer must have filed all tax returns, made all required estimated tax payments for the current year, and made all required federal tax deposits for the current quarter if the taxpayer is a business owner with employees.

IRS may compromise a tax liability on any of the following grounds:

• (1)  Doubt as to liability. There must be a genuine dispute as to the existence of amount of the correct tax debt.
• (2)  Doubt as to collectibility. Such doubt exists in any case where the taxpayer's assets and income are less than the full amount of the tax liability.
• (3)  To promote effective tax administration. An offer may be accepted on this ground if: (a) collection in full of the tax owed could be achieved, but (b) requiring payment in full would either create an economic hardship, or would be unfair and inequitable because of exceptional circumstances. (Reg. § 301.7122-1(b))

To request an OIC, taxpayers must apply via Form 656, Offer in Compromise.

• They also must submit Form 433-A (OIC), Collection Information Statement for Wage Earners and Self-Employed Individuals, and/or
• Form 433-B (OIC), Collection Information Statement for Businesses.
• A taxpayer submitting an OIC based on doubt as to liability must file a Form 656-L (PDF), Offer in Compromise (Doubt as to Liability), instead of Form 656 and Form 433-A (OIC) and/or Form 433-B (OIC).
• The OIC application generally must be accompanied by a $186 application fee.
• However, the fee is waived for certain low income taxpayers, or if the OIC is based on doubt as to liability. ( Form 656-B, Notice 2006-68, 2006-31 IRB 105, Sec. 4.03)

Except with regard to offers filed by low-income taxpayers, or based only on doubt as to liability, an OIC must be accompanied by a nonrefundable payment that depends on how the taxpayer is offering to pay.

• A taxpayer may propose to pay in a lump sum, i.e., an offer payable in five or fewer installments within five or fewer months after the offer is accepted. If such an offer is made, the taxpayer must include with the Form 656 a payment equal to 20% of the offer amount. This payment is required in addition to the $186 application fee.
• A taxpayer may propose to make periodic payments, i.e., six or more monthly installments made within 24 months after the offer is accepted. When submitting a periodic payment offer, the taxpayer must include the first proposed installment payment along with the Form 656. This payment also is required in addition to the $186 application fee. (Code Sec. 7122(c)(1))

Temporarily delay the collection process. One final option, if payment would create financial hardship, is to ask IRS to delay collection until the taxpayer is able to pay. If IRS determines that the taxpayer cannot pay any of his or her tax debt, it may report the taxpayer's account as currently not collectible and temporarily delay collection until the taxpayer's financial condition improves. Interest and penalties continue to accrue until the tax debt is paid in full.

The taxpayer may be asked to complete a Collection Information Statement (Form 433-F, Form 433-A or Form 433-B) and provide proof of financial status (this may include information about assets and monthly income and expenses). During a temporary delay, IRS will again review the taxpayer's ability to pay, and may also file a Notice of Federal Tax Lien to protect the government's interest in his assets. To request a temporary delay of the collection process or to discuss other payment options, contact IRS at 1-800-829-1040 (individuals) or 1-800-829-4233 (businesses).
