An installment agreement, authorized by IRC §6159, is simply a formal arrangement to pay your tax debt in monthly installments. It’s the most common resolution by a wide margin, because it doesn’t require proving hardship or negotiating a settlement — for most balances, it’s close to automatic.
The type you qualify for depends on how much you owe and whether you can pay the balance in full over time. Entering an agreement also carries a practical benefit beyond the payment schedule: the IRS generally releases active levies and won’t start new ones while the agreement is in good standing.
The types of agreement
There are four main varieties, from simplest to most involved:
- Guaranteed agreement — for individuals owing $10,000 or less who can pay within three years. The IRS must accept it if you qualify; no financial disclosure.
- Streamlined agreement — for balances up to $50,000, payable over 72 months. No financial statement required — the most common plan.
- Non-streamlined agreement — for balances above $50,000; requires a financial statement (Form 433-F or 433-A) and IRS review.
- Partial-payment installment agreement (PPIA) — for taxpayers who can’t pay the full balance before the collection statute expires; monthly payments are based on ability to pay, and the remainder is written off when the statute runs.
What it costs to set up
The IRS charges a setup fee that varies by how you apply and pay: the lowest fee is for a Direct Debit online application, higher fees apply for phone/mail or non-direct-debit plans, and low-income taxpayers can have the fee waived or reimbursed. Direct debit is usually the cheapest and also the route that unlocks lien withdrawal under Fresh Start. Interest and the (reduced) failure-to-pay penalty continue to accrue on the unpaid balance while you pay it down.
How a plan stops enforcement
This is the underrated benefit. A pending or active installment agreement generally prevents the IRS from levying, and it’s the most common route to getting an existing wage garnishment or bank levy released. For someone under active collection, getting a plan on file is often the fastest way to stop the bleeding — even before the larger question of whether an offer or hardship status might be a better long-term fit is settled.
Choosing between a plan and an offer
A streamlined installment agreement is easy, but "easy" isn’t always "cheapest." If your finances would support an accepted Offer in Compromise or currently-not-collectible status, paying a balance in full over 72 months could cost far more than settling. The right move is to compare your Reasonable Collection Potential against the full balance before defaulting to a payment plan.
