What are IRS Installment Agreements and How Can You Apply?
Installment agreements are one of the most common tools the IRS provides to collect unpaid tax balances while giving taxpayers breathing room to pay over time. They can stop many immediate collection actions (like levies) so long as the taxpayer stays current with the plan and future tax filings. In my 15+ years as a CPA helping clients resolve tax liabilities, I’ve found a well-structured installment agreement often preserves cash flow and prevents costly collection escalations — provided the plan is affordable and the taxpayer remains current.
Below I explain the main types of IRS installment agreements, the usual costs and trade-offs, and a clear, step-by-step approach to apply and manage a plan.
Types of IRS installment agreements (overview)
-
Short-term payment plan: Designed to pay the balance in 120 days or less. No long-term monthly arrangement; generally fewer fees but interest and penalties continue to accrue.
-
Long-term installment agreement (standard): A monthly payment plan that can stretch beyond 120 days. Traditionally this category includes a range of arrangements — streamlined setups for smaller balances and negotiated plans for larger or more complex debts.
-
Partial Payment Installment Agreement (PPIA): The IRS may accept smaller monthly payments that do not fully amortize the debt before the collection statute expires. PP IAs require financial disclosure and are subject to periodic review.
-
Direct‑debit and automated plans: These are the same legal agreements but use automatic electronic payments, which lowers the chance of default and typically reduces or eliminates certain administrative fees.
Note: The IRS updates eligibility rules, payment limits, and user-fee structures from time to time. Confirm current thresholds and fees on the IRS Payment Plans page (IRS: Payment Plans – Installment Agreements).
How the IRS typically groups plans (practical view)
Practitioners and taxpayers often think of installment agreements in three practical buckets:
- Quick/short-term plans (pay within 120 days).
- Streamlined long-term plans for smaller balances that the IRS can approve quickly (historically available for lower balances and fixed maximum terms).
- Customized/regular plans for larger balances or taxpayers who need a payment based on detailed financial information.
Which bucket you fall into depends on your balance, ability to pay, recent compliance (filing and estimated tax payments), and the IRS’s current criteria.
Costs to expect (fees, interest, penalties)
-
Setup/administrative fee: The IRS charges a user fee for establishing many long‑term installment agreements. Fee amounts and reductions for low‑income taxpayers change over time; reduced or waived fees are available for qualifying low‑income filers. Check the IRS Payment Plans page for the most recent fee schedule.
-
Interest: Interest accrues on unpaid tax from the original due date until paid in full. The rate is set quarterly by the IRS and compounds daily.
-
Failure-to-pay penalty: This penalty generally continues to apply to unpaid balances while you are on a plan (it may be lower than penalties that result from enforced collections but won’t disappear automatically).
-
Collection costs: If the IRS must take enforced collection actions (levies, seizing assets), you will face additional administrative costs and potential legal consequences.
In practice: choosing a direct‑debit installment agreement (auto pay) reduces the likelihood of missed payments and can lower administrative fees compared with other payment methods.
Who usually qualifies and common eligibility rules
Eligibility generally requires:
- A filed tax return for the periods the IRS is seeking to collect.
- Demonstrated ability to make a monthly payment that the IRS will accept.
- No recent defaults on prior IRS agreements (defaults make approval harder).
Lower-balance taxpayers and those who can pay within a set time frame (for example, within 72 months) typically qualify for faster, streamlined approval. Taxpayers with larger balances or complicated finances usually must provide financial statements (Forms 433‑F or 433‑A) and may have to propose a payment amount based on allowable expenses and income.
Step-by-step: How to apply (practical checklist)
-
Review your IRS notices and balance due. Confirm the exact amount, tax periods, and whether penalties or interest have been added.
-
File any unfiled tax returns immediately. The IRS will not usually approve a plan while returns are unfiled.
-
Gather documentation: pay stubs, bank statements, proof of expenses, last‑filed tax return, and the notice you received.
-
Decide how you’ll pay: full pay, short‑term (120 days), or monthly installment. For monthly plans, consider direct debit.
-
Apply online when possible: Use the IRS Online Payment Agreement tool (fastest route for many taxpayers). For detailed guidance about the online route, see our guide: How to Request an Installment Agreement Online.
-
If you can’t apply online or need a negotiated plan, submit Form 9465 (Installment Agreement Request) and, if requested, Form 433‑F or 433‑A to document finances.
-
Consider calling the IRS or working with a tax professional if your case involves business tax returns, employment‑based balances, or large debts.
-
When approved, set up automatic payments and confirm the date each month the IRS will withdraw funds. Keep proof of payment and IRS correspondence.

Practical tips that save money and reduce risk
-
Choose direct debit whenever possible — it reduces missed payments and can lower setup fees.
-
Offer a realistic payment. Proposing an amount you can’t sustain often leads to default and collection enforcement.
-
Continue to file and pay future taxes on time. Falling behind on subsequent taxes is the most common reason an agreement is defaulted.
-
Keep the IRS informed. If your financial situation changes, request a modification rather than simply missing payments. See our guide on Modifying an Existing Installment Agreement for how to proceed.
-
Compare alternatives. If your debt is large and your ability to pay is limited, an Offer in Compromise may be preferable — but it has strict qualification rules and a lengthy application process. Compare options in Installment Agreements vs. Offers in Compromise: Which is Right for You?
What happens if you default or miss payments
If you miss payments, the IRS can terminate the agreement and resume collection actions, including filing a Notice of Federal Tax Lien or issuing levies on bank accounts and wages. If you fall behind, contact the IRS immediately to request reinstatement or modification; proactively working with the agency is often less costly than letting the situation escalate.
When a Partial Payment Installment Agreement makes sense
A PPIA can be a practical solution when a taxpayer cannot fully repay the debt before the collection statute expires, and the IRS determines that a partial payment now plus possible future collections is in the government’s best interest. PP IAs require ongoing financial reviews; the IRS may request updated financial statements periodically.
My professional view and common mistakes I see
In my practice I see three recurring errors:
- Proposing payments without reviewing allowed IRS living expense standards — taxpayers overestimate what the IRS will accept.
- Choosing a plan without verifying current fee and interest rules (fees change, so confirm at the time you apply).
- Missing future tax payments after establishing the plan — the quickest route to default.
A sound approach: prepare a realistic budget, apply for direct debit, and, if necessary, work with a CPA or enrolled agent to submit the paperwork.
