Quick overview
An IRS installment agreement is a negotiated payment plan the IRS accepts so you can pay a past-due tax balance over time instead of all at once. These plans are a common, practical tool for individuals, small business owners, and tax professionals to manage liability without triggering immediate enforced collection (like levies or bank account seizures) while you make consistent payments. For the IRS’s official guidance, see the Installment Agreements page on IRS.gov (IRS.gov/payments/installment-agreements).
How installment agreements work
When you request an installment agreement, the IRS evaluates the amount you owe, your recent filing and payment history, and—sometimes—your financial situation. If approved, you’ll have a written agreement (or an online record) that spells out the monthly payment, due date, and duration. You remain liable for interest and penalties on the unpaid balance until it’s fully paid. Direct debit (automatic bank withdrawal) agreements typically reduce default risk and may have lower setup or maintenance costs.
Application methods
- Online: Many taxpayers can apply for an Online Payment Agreement through IRS.gov. This is the fastest method when eligible (see IRS link above). (IRS.gov)
- By phone or mail: You can also negotiate through an IRS Collections representative or submit Form 9465 (Installment Agreement Request) with your tax return or response to an IRS notice.
- Through a tax professional: Authorized representatives with Power of Attorney can apply on your behalf.
Note: IRS online eligibility rules, fee amounts, and balance thresholds can change. Always confirm current thresholds and setup fees using the IRS Installment Agreements page (IRS.gov/payments/installment-agreements).
Types of installment agreements — which one might fit?
The IRS provides several common types of agreements. Below is an overview and when each is typically appropriate:
-
Short-term payment plan
-
For taxpayers who can pay the balance within a short window (typically 120 days). These often carry no setup fee, but interest and penalties continue to accrue until paid. Use this when you expect a lump-sum in the near term.
-
Long-term (monthly) installment agreement
-
A longer schedule with monthly payments, usually used when the balance cannot be paid within the short-term window. These plans can be set up for several years depending on the balance and collection statute of limitations.
-
Streamlined installment agreement
-
A simplified option that can be approved without full financial disclosure when the taxpayer meets specific requirements. Streamlined agreements are common for smaller balances and for taxpayers who can reasonably demonstrate they can pay within a set period. For detailed eligibility and enrollment tips, see our article on streamlined installment agreements.

-
Partial-payment installment agreement (PPIA)
-
When you can’t pay the full tax balance over the collection statute period, the IRS may accept lower monthly payments based on a detailed financial analysis. A PPIA requires thorough financial disclosure and usually involves more review by the IRS.
-
Guaranteed and other low-balance options
-
There are special, simplified options historically available for very small balances or for filers who meet specific low-income criteria. Eligibility and thresholds change; consult IRS guidance and our small-balance article when in doubt.
Costs: setup fees, interest, and penalties
Entering an installment agreement reduces immediate collection risk but doesn’t stop interest or penalties. Costs you should plan for:
-
Setup or user fees: The IRS charges a fee to set up certain installment agreements, but fees vary by application method (online, phone, or paper), payment method (direct debit vs. non-direct debit), and whether you qualify for a reduced or waived fee (for example, low-income taxpayers or those who agree to direct debit may see lower fees). Confirm current fee amounts on IRS.gov.
-
Interest: The IRS charges interest on unpaid tax from the due date until paid in full. The rate is set quarterly and compounds daily; current rates appear on the IRS website.
-
Penalties: Two common penalties continue to accrue unless abated: the failure-to-pay penalty and possibly a failure-to-file penalty if returns are late. Entering an installment agreement does not eliminate these penalties, though penalty relief is possible in certain circumstances.
-
Collection enforcement costs: If the IRS had already begun enforced collection (levy, lien, seizure), additional administrative costs or actions could apply until the account is resolved.
Because interest and penalties compound, shorter agreements generally cost less in total dollars than longer ones even if the monthly payment is higher.
Eligibility: who can get an installment agreement?
Most taxpayers who have filed required tax returns and cannot pay in full may qualify for an installment agreement. Common eligibility considerations include:
- Filed and current tax returns — the IRS generally requires all returns to be filed.
- Current compliance — if you owe other federal obligations or have active collection actions, that can affect eligibility and the type of plan offered.
- Ability to pay — for partial-payment plans the IRS will require detailed financial disclosure.

How to calculate a realistic monthly payment
To pick a plan the IRS is likely to accept and that you can sustain, calculate a payment amount based on a conservative budget: list net monthly income, non-discretionary expenses (housing, utilities, insurance, minimum debt payments), and flexible spending. Subtract expenses from income to find the maximum feasible payment without risking default. For a worksheet and method, see our calculator guide. Internal resource: How to Calculate a Realistic Monthly Payment for an Installment Agreement — https://finhelp.io/glossary/how-to-calculate-a-realistic-monthly-payment-for-an-installment-agreement/
Example scenarios (illustrative)
- Individual with $12,000 owed: If a taxpayer chooses a 36-month plan, a simple division gives $333/month plus interest and penalties; a direct-debit plan might be more likely to be approved and less likely to default.
- Small business owing $20,000: A long-term plan with lower monthly payments preserves cash flow for operations but will increase total interest and penalty cost.
These are illustrative; run the numbers for your exact balance, current IRS interest rate, and likely penalties.
Common mistakes and how to avoid them
- Assuming payments stop interest: Interest accrues until the balance is paid. Always factor it into total cost.
- Missing future tax filings or estimated payments: Maintain current tax compliance, including paying estimated taxes, to avoid default.
- Choosing a plan you can’t sustain: Overly optimistic budgets lead to default and possible agreement termination.
- Ignoring IRS notices: Prompt response preserves negotiation options and prevents escalation.
If you default, the IRS can revoke the agreement and pursue enforced collection; read our guide on consequences and fixes. Internal resource: Defaulting on an Installment Agreement: Consequences and Fixes — https://finhelp.io/glossary/defaulting-on-an-installment-agreement-consequences-and-fixes/
Modifying or ending an agreement
If your financial circumstances change, you can request a modification. The IRS will require updated information and may accept a higher or lower payment plan depending on your situation. If you pay off the balance early, the agreement ends; request confirmation in writing for your records. For more on modifications, see our guide on modifying or revoking an existing agreement.
Practical application tips from experience
In my practice advising taxpayers for more than a decade, these approaches work consistently:
- Use direct debit whenever possible: it reduces missed payments and often lowers set-up friction.
- Start with the most aggressive realistic payment you can sustain: shorter plans reduce total interest and penalties.
- Keep records of all communications and payments; get written confirmation of the agreement and any changes.
- If you have irregular income, propose variable or seasonally adjusted payment amounts with supporting documentation — the IRS will consider reasonable plans.
- Consider professional help (CPA or tax attorney) when balances are large or if liens/levies are already in place.
When to consider alternatives
If the balance is large and your ability to pay is permanently limited, the IRS offers options such as Offer in Compromise (OIC) or currently not collectible (CNC) status. Choosing between an installment agreement and an OIC depends on your long-term ability to pay; see our comparison article Choosing Between an Installment Agreement and an Offer in Compromise for guidance.
