Quick comparison

  • Installment agreement: spreads tax debt into monthly payments; interest and some penalties usually continue to apply unless abated.
  • Penalty abatement: removes specific penalties (if approved) but generally does not stop interest on unpaid tax.

Why this decision matters

Choosing between negotiating a payment plan and asking the IRS to waive penalties affects your total cost, cash flow, and time to become current. In many cases the correct strategy is both: request abatement for penalties you can document and place the remaining balance on an affordable installment arrangement.

How each option works (practical view)

  • Installment agreement

  • What it does: Sets a formal monthly payment schedule with the IRS so you can pay the tax balance over time.

  • Who it fits: Taxpayers who can’t pay the full balance now but can make regular payments.

  • Common paths: streamlined installment agreements (often available online for many taxpayers with total liabilities at or below IRS thresholds) and longer-term plans that require financial disclosure for lower payments (IRS Online Payment Agreement).

  • Things to watch: setup fees or user fees may apply; interest continues to accrue on unpaid tax and some penalties may still apply unless abated. Consider using direct debit to lower default risk and some setup fees.

  • Penalty abatement

  • What it does: Requests removal of assessed penalties (failure-to-file, failure-to-pay, etc.) based on reasonable cause, first-time penalty relief, disaster/identity-theft relief, or other IRS programs.

  • Who it fits: Taxpayers with documented reasons (illness, natural disaster, death in the family, or other circumstances outside their control) or those eligible under the First-Time Penalty Abatement (FTA) criteria (IRS Penalty Relief).

  • How to request: Submit a reasonable-cause letter, call the IRS, or use the IRS’s online tools where available. Keep clear documentation — medical records, insurance claims, or proof of disaster help build a strong case.

Decision framework: when to pick which

  1. Short-term cash stress but solid documentation of why you missed filing or paying? Request penalty abatement first to remove penalties; then set an installment agreement for any remaining balance.
  2. Owe a smaller balance you can amortize quickly? A short-term installment agreement may cost less overall than spending time building a penalty-abatement case.
  3. Eligible for First-Time Penalty Abatement? Apply — it’s often the fastest way to remove penalties if you meet IRS criteria.
  4. Large debt or inability to pay even with an installment plan? Explore alternatives like an Offer in Compromise after consulting a tax pro.

Practical steps to act (recommended)

  1. Check your IRS account online for current balances and penalties at IRS.gov.
  2. Gather proof for abatement (medical, death certificates, disaster declarations, identity-theft reports) or prepare a concise reasonable-cause statement.
  3. Consider applying for First-Time Penalty Abatement before negotiating the payment plan if you meet that program’s conditions (IRS Penalty Relief).
  4. Apply for an installment agreement online if eligible or call the IRS; use direct debit when possible to reduce fees and default risk (Setting Up an Affordable Installment Agreement with the IRS).
  5. If penalties remain, submit a written reasonable-cause request or follow IRS instructions for penalty relief (How to Ask the IRS for a Penalty Abatement: Evidence That Works).

Common mistakes I see in practice

  • Waiting to act: penalties and interest keep growing. Even a modest installment payment stops enforced collection actions sooner.
  • Poor documentation: vague or unsupported abatement requests are denied. Provide dated, corroborating evidence.
  • Assuming abatement stops interest: interest usually continues on unpaid tax; abatement generally removes penalties only.
  • Not comparing total cost: sometimes an installment plan with interest costs less than the time and effort required to win abatement.

When to get professional help

If the debt is large, there are multiple years or payroll tax issues, or you’ve been issued a levy or lien, consult a tax attorney or enrolled agent. In my 15+ years helping clients, professional representation speeds complex abatement cases and lowers the chance of defaults on installment plans.
