Quick overview

Installment agreements are formal payment plans the IRS uses to collect unpaid federal taxes when a taxpayer cannot pay the full balance immediately. They stop many aggressive collection steps while active, let you spread payments into manageable amounts, and give time to budget and avoid bankruptcy or enforced levies in many cases. In my 15+ years helping clients, a correctly chosen installment agreement often preserves cash flow and prevents escalating collection costs.

Who can use an installment agreement?

Most individual taxpayers and small businesses who have filed required federal tax returns and owe a federal tax balance can apply for an installment agreement. Key eligibility points:

  • Required filings: All required returns must be filed before the IRS will approve most installment agreements. (See IRS Payment Plans/Installment Agreements.)[1]
  • Outstanding balance: There are different agreement types with different balance thresholds (short-term vs. long-term vs. streamlined). If you owe a very large balance or have complex finances, the IRS may request additional financial information.
  • Compliance expectations: To keep an agreement, you must make timely payments and remain current on future filings and taxes.

Note: State tax agencies run separate programs; an IRS installment agreement does not automatically cover state tax debt.

What are the main types of installment agreements?

Below are the commonly available plans and when they make sense. The IRS updates exact dollar thresholds and user fees periodically, so check the IRS pages listed at the end before applying.[1][2]

  1. Short‑Term Payment Plan
  • Best for: Taxpayers who can pay in full within 120 days. No setup fee is charged by the IRS for short‑term plans.
  • Pros: Quick, no setup fee, fewer formal requirements.
  • Cons: Interest and penalties continue until paid in full.
  1. Long‑Term Installment Agreement (Payment Plan)
  • Best for: Taxpayers who need more than 120 days to pay and owe more than the short‑term threshold.
  • Pros: Spread payments over months or years; can be set up online for many cases.
  • Cons: IRS user fees apply (reduced if you choose direct debit). Interest and penalties continue until balance is paid.
  1. Streamlined Installment Agreement
  • Best for: Taxpayers with relatively smaller tax liabilities who meet the IRS streamlined criteria (for example, owing up to certain thresholds and agreeing to pay in full within a set period).
  • Pros: Faster approval and less documentation required.
  • Cons: Not available if the IRS needs a full financial review.
  1. Guaranteed Installment Agreement
  • Best for: Taxpayers who meet very specific, limited criteria (historically available for smaller balances and well‑documented cases).
  • Pros: Guaranteed acceptance if you meet criteria.
  • Cons: Strict eligibility rules.
  1. Partial‑Payment Installment Agreement (PPIA)
  • Best for: Taxpayers who cannot fully pay their tax liability but can make reduced monthly payments that the IRS accepts based on their financial condition.
  • Pros: May be the only realistic alternative to an Offer in Compromise for taxpayers with limited ability to pay.
  • Cons: Often requires a full financial statement (Form 433 series) and periodic reviews; can be time‑limited and may still result in a future collection action if circumstances change.
  1. Payroll Deduction Installment Agreement
  • Best for: Taxpayers whose employers can deduct the IRS‑approved payment from payroll.
  • Pros: Lowers the risk of missed payments.
  • Cons: Requires employer cooperation and coordination.

Typical fees, interest, and penalties

The IRS charges user fees to set up many long‑term installment agreements; however, short‑term plans generally have no setup fee and direct‑debit plans typically have a lower fee. Low‑income taxpayers may qualify for reduced or waived fees. Interest and failure‑to‑pay penalties continue to accrue until the balance is paid in full. Because these figures change, confirm current fees on the IRS Payment Plans page before applying.[2]

How to apply — step‑by‑step (practical checklist)

  1. Confirm you’ve filed all required tax returns. The IRS will not enter most plans if returns are missing.[1]
  2. Verify your total balance due, including penalties and interest, using your IRS account online or recent notices.
  3. Decide the plan type that best fits your cash flow and total balance. If unsure, start with the Online Payment Agreement tool.[2]
  4. Gather supporting documents you may need: recent pay stubs, monthly expense list, bank statements, and copies of filed returns (Form 1040, business returns, etc.). A full financial statement (Form 433‑F or Form 433‑A) may be required for negotiated or partial‑payment plans.
  5. Apply:
  • Online: Use the IRS Online Payment Agreement (OPA) tool for many individual installment agreements — this is the fastest route for straightforward cases.[2]
  • By phone: Call the number on your IRS notice to discuss options.
  • By mail: Complete and mail Form 9465 (Installment Agreement Request) — or include Form 9465 with your tax return to request a payment plan.
  1. Choose payment method: Direct debit (automated bank withdrawal) reduces default risk and often lowers setup fees. You can also pay by check, money order, or credit card (convenience fees apply for cards).
  2. Keep payments current and keep filing future returns on time. Missing payments can default the agreement and lead to enforced collection actions.

What happens if you miss a payment or default?

If you miss payments, the IRS will typically send notices and may default the agreement. Consequences can include enforced collection (levies on wages or bank accounts), reinstatement of collection activity, or a requirement to pay the balance in full. If you default, contact the IRS immediately — you may be able to reinstate the plan, negotiate modified terms, or request temporary relief if you can show changed financial circumstances.

In my practice, reestablishing contact quickly and proposing a realistic, documented modified payment plan almost always reduces the risk of immediate enforced collection.

Comparing installment agreements with other options

  • Installment Agreement vs Offer in Compromise (OIC): An installment agreement pays the full tax over time; an OIC seeks to settle for less than full liability when the taxpayer can’t realistically pay. If you think you qualify for an OIC, see our guide “When an Offer in Compromise Is a Better Option Than an Installment Agreement” for comparative criteria and next steps.Internal link: Choosing Between an Installment Agreement and Offer in Compromise

  • Installment Agreement vs Bankruptcy: Bankruptcy can discharge some types of tax debt under narrow conditions; however, it has broader credit and legal consequences. For many taxpayers, an installment agreement is less damaging to credit and more flexible. See our primer “What Is an Offer in Compromise?” for other alternatives to long‑term payment plans.Internal link: What Is an Offer in Compromise? Eligibility, Process, and Alternatives

Real‑world examples (anonymized)

  • Case A: A taxpayer with a $15,000 balance who could not pay immediately qualified for a long‑term direct‑debit installment agreement. By choosing a 60‑month term and prioritizing other high‑interest debt, the taxpayer avoided bank levies, maintained regular cash flow, and paid the balance with manageable monthly payments.

  • Case B: A small business with cyclical revenue used a payroll deduction agreement to ensure monthly IRS payments aligned with cash receipts. The employer’s cooperation reduced missed payments and administrative friction.

Practical tips and best practices

  • Choose direct debit whenever possible — it reduces missed payments and often lowers setup fees.
  • Don’t ignore IRS notices. Responding early preserves options and reduces penalties for noncompliance.
  • Reevaluate your plan if your financial situation improves — paying off the debt early saves interest.
  • Keep records of every payment and communication with the IRS.
  • If you owe state taxes as well, contact your state tax agency; many states offer installment plans with different rules.
  • Consider professional help if your case involves a large balance, business taxes, or complex financials. In my experience, a tax professional can streamline negotiations and avoid costly mistakes.

When to seek other relief

If your financial situation leaves little to no ability to pay even a reduced monthly amount, you may qualify for a Partial‑Payment Installment Agreement or an Offer in Compromise. These options typically require a full financial disclosure and are more document‑intensive. If you believe you have very limited ability to pay, see our guides on Offers in Compromise for the next steps and required documentation.Internal link: Inside an Offer in Compromise: How the IRS Evaluates Your Financial Picture

Documentation and recordkeeping

Keep copies of:

  • The IRS agreement confirmation or approval letter.
  • Bank statements showing direct‑debit transactions.
  • Proof of mailed payments (money order receipts, certified mail tracking).
  • Notices from the IRS and any correspondence.

These records help resolve disputes and prove compliance in case of future IRS questions.
