Overview
An installment agreement with the IRS allows a taxpayer to pay a federal tax liability over time instead of in a lump sum. While these plans provide breathing room, they are not fixed for life. When a taxpayer’s financial circumstances change materially — for example through job loss, separation, or unexpectedly high medical bills — continuing with the original terms can become impossible. The IRS permits taxpayers to request changes, but you must document the change and follow established procedures (IRS Payment Plans — Installment Agreements: https://www.irs.gov/individuals/payment-plans-installment-agreements).
This article explains common life events that affect installment agreements, when to contact the IRS, documentation to prepare, modification options (including Partial-Payment Installment Agreements), and how a financial advisor or tax professional can help. I’ve advised taxpayers through dozens of modifications in my practice; the practical tips below reflect common pitfalls I’ve seen and strategies that work.
When a life change should trigger a review of your installment agreement
Not every personal change requires a modification. Consider a review when any of the following materially affects your monthly cash flow or your ability to meet the agreed payment:
- Job loss or an extended reduction in income
- Divorce or separation that changes household income/support
- Birth or adoption of a child that increases recurring expenses
- Major medical expenses or a disability that increases costs and reduces earning ability
- Sudden housing cost change (eviction, foreclosure, or moving to a higher-cost area)
- Business closure or significant drop in self-employment income
If the change reduces your disposable income below the payment amount, call the IRS or your tax professional immediately. Early contact preserves options and is better than missing payments and risking default or enforced collection.
How the IRS evaluates modifications
The IRS evaluates a request to modify an installment agreement by reviewing your ability to pay. They will generally want current income, living expenses, and proof of extraordinary costs. The IRS uses Collection Financial Standards as a benchmark for allowable living expenses (see IRS Collection Financial Standards: https://www.irs.gov/businesses/small-businesses-self-employed/collection-financial-standards).
Options the IRS may offer include:
- Recalculation of monthly payments based on reduced income (standard modification)
- Temporary suspension of payments for a short period if income loss is temporary
- Conversion to a Partial-Payment Installment Agreement (PPIA) if you cannot fully pay the liability within the statutory collection period (see FinHelp article: How to Request a Partial Payment Installment Agreement (PPIA): https://finhelp.io/glossary/how-to-request-a-partial-payment-installment-agreement-ppia/)
- Currently Not Collectible (CNC) status if your income and assets are insufficient to make payments without hardship
The IRS will not automatically reduce your payments because of an unverified claim. Documentation is essential.
Typical documentation to prepare
When you ask the IRS to review your agreement, gather materials that show the financial change and current monthly budget. Useful documents include:
- Recent pay stubs or proof of unemployment benefits
- Bank statements for the last 3 months
- Copies of divorce decrees, child support orders, or settlement documents
- Medical bills, insurance denial letters, and doctor statements
- Proof of new expenses related to a child (daycare receipts, adoption fees)
- Profit-and-loss statements for self-employed taxpayers
If you retain a tax professional, they can package these documents and negotiate with the IRS on your behalf.
Real-world examples (anonymized)
1) Job loss: I worked with a client who lost steady employment and could not make $450 monthly payments. After submitting unemployment records and a revised budget, the IRS approved a temporary lower payment until the client found new work.
2) Divorce: A client who was previously filing jointly became responsible for the full tax debt after divorce. By providing the divorce decree and updated income documentation, we obtained a recalculation of monthly payments to reflect single-income status.
3) New child: A young couple had a baby and higher childcare costs. They provided daycare receipts and updated housing budgets and successfully reduced their monthly installment for one year.
These cases show the IRS responds when presented with timely, verifiable evidence.
Common modification pathways and how they differ
-
Streamlined or standard installment agreement modification: For taxpayers who still can fully repay the tax but need a lower monthly amount, the IRS may adjust the term or payment amount.
-
Partial-Payment Installment Agreement (PPIA): If you cannot pay the full liability within the collection statute period, a PPIA spreads payments that might not satisfy the full debt before the statute of limitations. Eligibility and process are detailed in our guide on requesting a PPIA (https://finhelp.io/glossary/how-to-request-a-partial-payment-installment-agreement-ppia/).
-
Currently Not Collectible (CNC): If your necessary living expenses exceed your income and you have no non-exempt assets to levy, the IRS may place the account in CNC status, temporarily halting collection activity. CNC is not forgiveness; interest and penalties generally continue to accrue.
-
Offer in Compromise (OIC): If your ability to pay is minimal relative to the tax owed, an OIC may permanently settle the debt for less than the full amount. OICs require thorough documentation and have stricter eligibility rules (IRS Offer in Compromise: https://www.irs.gov/payments/offer-in-compromise).
Practical steps to request a modification
- Review your current agreement terms and payment history. Note upcoming due dates and any defaults.
- Gather documentation showing the life change and current finances (see list above).
- Contact the IRS Collection Department listed on your notice or your local IRS office. You can also work with a CPA, enrolled agent, or tax attorney.
- If eligible for online changes, use the IRS Online Payment Agreement tool for simple requests, but be prepared to submit financial statements for more complex changes (https://www.irs.gov/payments/online-payment-agreement-application).
- Follow up in writing, keep copies of every submission, and obtain the IRS representative’s name and contact details.
Mistakes to avoid
- Waiting to contact the IRS until after missing payments. Proactive communication preserves options.
- Submitting incomplete or unorganized documents — this delays review and may result in denial.
- Assuming a modification is automatic; the IRS needs evidence and may require negotiation.
- Ignoring tax notices. They often contain the phone number and steps for requesting changes.
How professionals can help
In my practice, we often handle the first call, assemble the financial package, and prepare the appropriate forms (e.g., Form 433-A or 433-F for individuals when requested by the IRS). Working with a tax professional can reduce errors, improve the quality of documentation, and increase the chances of a favorable change. If you choose a representative, ensure they are an enrolled agent, CPA, or tax attorney and that they provide a written engagement letter detailing fees and services.
Interaction with other resolutions and next steps
Life changes may also make other resolution options more appropriate. For example:
- If your balance is relatively small and you now have irregular income, see our guide on qualifying for an online installment agreement (https://finhelp.io/glossary/how-to-qualify-for-an-online-installment-agreement-with-the-irs/) for faster options.
- If you default and can’t reapply under standard terms, review our article on reapplying after default to understand penalties and eligibility (https://finhelp.io/glossary/how-to-reapply-for-an-installment-agreement-after-default/).
These internal resources help you choose the right path depending on whether the change is temporary or permanent.
Post-modification obligations and watch-outs
- Keep up with any modified monthly payments. Missing payments after an approved modification may terminate the agreement and lead to enforced collection.
- Continue filing future tax returns and paying future taxes timely. Falling behind on new taxes can jeopardize an existing installment agreement.
- Understand how interest and penalties continue to accrue. Even under CNC, interest and penalties may remain unless otherwise resolved.
Quick checklist to act now
- Gather three months of bank statements and pay stubs or unemployment notices.
- Create a simple budget showing essential expenses vs. income.
- Call the IRS number on your notice or consult a tax professional.
- Consider temporary options like reduced payments, CNC, or PPIA depending on your situation.
