Partial Payment Installment Agreement vs. Full-Pay Installment Agreement
One pays the balance in full before the collection statute runs out. The other accepts, by design, that it may not. The Internal Revenue Manual treats them as different procedures with different paperwork, not two prices on the same plan.
Quick Answer
The dividing line is not the paperwork — a PPIA and a non-simple full-pay agreement both require a full Collection Information Statement. It is what each one accepts as the outcome. A full-pay agreement is built to retire the balance; the Internal Revenue Manual authorizes a PPIA specifically for the case where full payment will not happen before the Collection Statute Expiration Date, and builds in a periodic financial review and, in some cases, a CSED-extension waiver, because the agreement may outlast the statute it would otherwise run against. Which one applies is the IRS's determination on the taxpayer's actual financial statement, not a choice made on this page.
Partial Payment Installment Agreement (PPIA)
Advantages
- The Internal Revenue Manual states the IRS can grant a PPIA when full payment cannot be achieved by the Collection Statute Expiration Date and the taxpayer has some ability to pay.
- Can apply where assets are minimal, illiquid, needed for income production, or where liquidating them would cause economic hardship.
- Stops enforced collection the same way any accepted installment agreement does, while it is in effect.
Disadvantages
- The Internal Revenue Manual states a full Collection Information Statement is required for all PPIAs — Form 433-A and/or Form 433-B, to determine ability to pay.
- Group manager approval is required, along with any CSED extension, under Delegation Order 25-2.
- The Internal Revenue Manual describes a two-year financial review process, and a waiver requirement in some circumstances tied to the taxpayer's only means of paying being a continuation of the agreement past the original CSED.
- By design, some or all of the remaining balance may not be paid before the collection statute runs, which is different from a plan built to fully pay the debt.
Best For
Cases where the IRS's own financial review shows some ability to pay, but not enough to fully pay the liability before the collection statute expires.
Typical Cost
The IRS publishes setup fees that vary by plan type and application method; this page does not restate the current figures because they change on the IRS's own schedule.
Full-Pay Installment Agreement
Advantages
- No full financial statement is required at the Guaranteed or Simple Payment Plan thresholds — see our resolution pages on each.
- The balance is fully paid by design, rather than accepting a partial recovery before the collection statute runs.
- Generally faster to set up at the thresholds that do not require a full Collection Information Statement.
Disadvantages
- Above the Simple Payment Plan's aggregate-balance threshold, or where the case does not otherwise qualify, a full Collection Information Statement is required here too — the same paperwork as a PPIA, for a different agreement type.
- Requires a monthly payment large enough to fully retire the balance within the plan's term, which is not always realistic against actual income and allowable expenses.
- Penalties and interest continue to accrue for the life of the agreement, the same as any installment agreement.
Best For
Cases where the taxpayer's income and allowable expenses support a monthly payment that retires the full balance before the collection statute or the agreement's term ends.
Typical Cost
The IRS publishes setup fees that vary by plan type and application method; this page does not restate the current figures because they change on the IRS's own schedule.
The Verdict
The dividing line is not the paperwork — a PPIA and a non-simple full-pay agreement both require a full Collection Information Statement. It is what each one accepts as the outcome. A full-pay agreement is built to retire the balance; the Internal Revenue Manual authorizes a PPIA specifically for the case where full payment will not happen before the Collection Statute Expiration Date, and builds in a periodic financial review and, in some cases, a CSED-extension waiver, because the agreement may outlast the statute it would otherwise run against.
