Stop a Returned Offer: Form 656 Fee, 20% Payment, and Checklist for U.S. Filers

By /

The Form 656 fee is a fixed amount stated on the form and is nonrefundable once the IRS accepts your envelope or online submission. Beyond that fee, you must also send an initial payment with your Offer in Compromise, either a portion of your total offer amount if you’re paying in a lump sum, or your first installment if you’re proposing periodic payments. The one major exception is the Low-Income Certification, which waives both the fee and the initial payment for individuals who meet the income thresholds.

TL;DR:

  • The $205 application fee for Form 656 is nonrefundable and applies regardless of the debt amount, unless you qualify for a Low-Income Certification.
  • Businesses must pay a separate $205 fee for each legal entity filing an Offer in Compromise, while sole proprietors are treated as individuals.
  • The initial payment for a lump-sum offer is 20% of the total offer amount, paid as a separate instrument from the fee, and failure to include both leads to offer rejection.
  • For periodic payment offers, the first installment is due along with the fee, and missing a payment during review results in automatic rejection without appeal.
  • Using electronic payment methods like EFTPS or IOLA simplifies compliance, while mailed payments must be separate checks or money orders payable to “United States Treasury” in U.S. dollars.

Understanding the Form 656 Fee and Initial Payment Basics

That $205 figure isn’t an estimate or a starting point. It’s printed directly on the current Form 656 (Rev. 4-2025) and repeated throughout the Form 656-B booklet, and it applies whether you’re settling $8,000 or $800,000 in back taxes. The application fee for form 656 doesn’t scale with your debt. It’s a flat processing cost the IRS charges to open your case.

Here’s where a lot of taxpayers get tripped up: the fee for form 656 and the initial offer payment are two completely separate obligations. Submitting form 656 fee money alone, without an accompanying initial payment, will get your offer bounced back. The IRS treats these as distinct financial commitments, and understanding form 656 fees means understanding that duality from the start. One check covers your right to have the offer reviewed. The other is a good-faith payment toward whatever settlement you’re proposing.

Form 656 itself is the application that lets individuals and businesses ask the IRS to settle a tax debt for less than the full amount owed. It’s the vehicle for the entire Offer in Compromise program, and the IRS Offer in Compromise guidance walks through eligibility basics before you ever get to the payment questions. Get the payment mechanics wrong, though, and none of the eligibility analysis matters. Your packet gets returned before an examiner even looks at your financials.

Quick Payments Checklist Before You Submit Form 656

Before you seal the envelope or hit submit online, run through this list. It catches the mistakes that cause the most returned offers.

  • Application fee: a set nonrefundable fee, sent as its own separate payment instrument, not combined with anything else.
  • Initial payment: a required portion of your lump-sum offer or your first periodic installment, sent as a second, separate payment.
  • Form 433-A (OIC) attached if you’re an individual, or Form 433-B (OIC) if you’re filing as a business entity.
  • Electronic payment preferred: use EFTPS or your Individual Online Account (IOLA) whenever you can.
  • Paper alternative: separate checks, cashier’s checks, or money orders made payable to “United States Treasury,” in U.S. dollars only.
  • Never send cash. No exceptions.
  • Keep proof of every electronic transfer confirmation number and copies of everything you mail.

Pro Tip: Photocopy the entire packet, front and back, before it leaves your hands. If the IRS claims a payment or form was missing, your copy with a certified mail receipt is the only thing standing between you and a returned offer.

How Much Is the Form 656 Application Fee, and Who Must Pay It

The standard cost of submitting form 656 is $205, and it’s nonrefundable once processing begins. That’s the baseline every taxpayer should assume applies to them unless they qualify for a specific exception.

Two exceptions exist, and they work very differently.

Low-Income Certification waives the fee entirely for individuals whose income falls below a specific threshold. The IRS applies one of two tests: your adjusted gross income compared to a published table, or your household’s monthly income measured against 250% of the HHS poverty guidelines. Meet either test, and you check a box on Form 656 instead of writing a check.

Doubt as to liability is a different animal altogether. If you’re not disputing your ability to pay but disputing whether you actually owe the tax in the first place, you file Form 656-L instead of the standard Form 656, and no application fee applies at all. This route is narrower than most taxpayers assume. It only fits genuine disputes about the underlying liability, not disputes about your finances.

Illustration of Form 656 fee exception paths

Business filers face a rule that catches people off guard: you owe a separate application fee for every legal entity. A corporation, an LLC taxed as a corporation, and a partnership each require their own Form 656 and their own $205 payment if they’re each carrying separate tax debt. Sole proprietorships are the exception here. Since a sole proprietorship isn’t a separate legal entity from its owner, it’s treated under the individual rules, including potential eligibility for Low-Income Certification.

If you’re running a business with unfiled return issues layered on top of an OIC consideration, sort out the filing gaps first. An offer built on top of unfiled returns almost never survives IRS review, regardless of how cleanly you handle the processing fee for form 656.

Initial Payment Rules: Lump-Sum vs. Periodic Offers

Once you’ve settled the application fee question, the initial payment is where most of the real money changes hands, and where the math actually matters.

Lump-sum cash offers require an upfront payment equal to 20% of your total offer amount, submitted with Form 656. This initial payment is nonrefundable and will be applied toward your outstanding tax liability if your offer is rejected, as described in the Form 656-B booklet.

Periodic payment offers require including your first proposed monthly installment with the application, then continuing those payments every month while the IRS reviews your case, which can take a year or longer. The full offer amount is proposed to be paid in regular installments within a period specified by IRS rules, as described in Tax Topic 204.

Here’s the sequence for calculating your own numbers:

  1. Determine your total offer amount based on your reasonable collection potential (what the IRS believes it could realistically collect from you).
  2. Decide between lump-sum and periodic based on your cash position. Lump-sum generally resolves faster; periodic spreads the burden.
  3. For lump-sum, multiply your offer amount by 20% to get your required initial payment.
  4. For periodic, divide your offer amount by your proposed number of months (up to 24) to set your installment size.
  5. Send that initial payment and your $205 application fee as two separate instruments, dated the same day if paying electronically.

Missing a periodic payment during review is treated as a default, and it can result in your offer being returned without further consideration. There’s no grace period built into the process, and the IRS won’t chase you down to remind you the payment is late.

One number worth remembering: every dollar you send in as an initial payment, whether the offer succeeds or fails, generally ends up applied to your tax debt rather than refunded, per IRS Offer in Compromise guidance. Budget these payments as real money leaving your pocket toward your liability, not as a refundable deposit you might get back if things don’t work out.

How to Make Payments: EFTPS, Online Account, and Paper Checks

You have three practical ways to send money to the IRS with your offer, and each has its own procedural quirks worth knowing before you pick one.

EFTPS (Electronic Federal Tax Payment System) lets you schedule payments directly from your bank account. After you complete a transfer, EFTPS generates a 15-digit confirmation number. Write that number directly on your Form 656 or attach it on a cover sheet. Examiners cross-reference these numbers against IRS payment records, and a missing confirmation number is one of the more common reasons a packet gets flagged for follow-up.

Individual Online Account (IOLA) lets individuals prepare their offer, run the numbers on what they might reasonably propose, and submit payments electronically, all within one online session. The IRS points taxpayers toward this option specifically because it eliminates most of the paperwork errors that plague mailed submissions. If you’re comfortable working online, this route cuts down significantly on the small mistakes that cause delays.

Paper payments remain fully acceptable if you’d rather mail your offer. Use separate checks, cashier’s checks, or money orders, each made payable to “United States Treasury,” each in U.S. dollars. Never send cash under any circumstances. Physically attach both payments to the front of your Form 656 packet so they can’t get separated during processing.

A few procedural details that trip people up:

  • If you’re paying electronically but mailing your paper forms, the electronic payment needs to be dated the same day you mail the offer, not before and not after.
  • Keep your EFTPS confirmation number and any bank transfer receipts in the same file as your copy of Form 656.
  • If you’re submitting through IOLA, save or screenshot your confirmation page before closing the session.
  • Double-check the payee line on every paper instrument. “United States Treasury” is the only acceptable payee, and variations get rejected by IRS lockbox processing.

Pro Tip: If you’re unsure whether your bank supports same-day EFTPS scheduling, test it a week before your actual submission deadline. Some banks require 24 to 48 hours to process an EFTPS transfer, and discovering that on the day you planned to mail your offer creates an avoidable delay.

What Happens if You Omit the Fee or Your Payment Is Returned

Missing payments trigger one of the more frustrating outcomes in the entire OIC process: the IRS simply returns your offer without a substantive review. Your financial disclosures, your hardship story, your carefully calculated reasonable collection potential, none of it gets examined if the payment piece is incomplete.

There’s no appeal process for a returned offer based on missing or incorrect payments. You can’t argue your way past a payment problem. The only path forward is resubmitting the entire packet with corrected payments, which restarts your position in the review queue and can add months to your timeline.

If a check bounces or a money order gets rejected for insufficient funds after the IRS has already processed it as received, the consequences compound. The IRS may treat the offer as having failed a payment term, which can result in the same return-without-review outcome. And because these payments are generally nonrefundable and applied toward your tax liability rather than sent back to you, a returned or failed payment doesn’t erase your obligation. It just delays and complicates the same debt you were trying to resolve.

If you discover a payment issue after submission, act quickly. Contact the IRS unit processing your offer, request written confirmation of what they received and when, and replace any deficient payment as fast as your bank allows. Document every call, every letter, and every confirmation number. Offers get returned often enough for preventable reasons that a clean paper trail is your best protection if a dispute arises later.

Low-Income Certification: Checking Eligibility and What It Changes

The Low-Income Certification is the single biggest exception to everything described above, and it’s worth checking before you send a dime.

The IRS uses two qualifying tests, and you only need to meet one:

  • AGI test: your adjusted gross income from your most recent filed return falls at or below the threshold in the IRS’s published table, which scales with household size.
  • Household income test: your gross monthly household income, multiplied out annually, falls at or below 250% of the HHS poverty guidelines for your household size and state.

To claim the certification, you check the designated box on Form 656 and complete the accompanying worksheet in the Form 656-B booklet. You don’t need to prepay anything to make the claim. If your numbers qualify, you submit the offer with no application fee and no initial payment attached at all, per Tax Topic 204.

That exemption only covers the period while your offer sits under IRS consideration. Once the offer is accepted, your first actual payment toward the settled amount becomes due according to the payment terms you proposed. Low-Income Certification defers payment obligations. It doesn’t eliminate the eventual payment on an accepted offer.

A few practical steps before you claim it:

  • Pull your most recent filed tax return and compare your AGI directly against the published threshold table in the current Form 656-B.
  • If you’re closer to the household income test, gather pay stubs or bank statements covering the most recent three months to substantiate your monthly figure.
  • Keep this documentation on hand even though you’re not required to submit it upfront. The IRS can request verification during review, and having it ready avoids a scramble later.
  • If your income fluctuates seasonally or you’re self-employed, calculate the test using an averaged monthly figure rather than your single highest month.

Business-Specific Considerations and Joint or Separate Liabilities

Businesses face a structurally different set of rules than individuals, and conflating the two is one of the more expensive mistakes taxpayers make.

Any corporation, partnership, or multi-member LLC taxed as a corporation must file its own Form 433-B (OIC) and pay its own $205 application fee, separately from any offer the business owner might file personally. If a business owner owes personal income tax and the corporation separately owes payroll tax, that’s two distinct offers, two separate fees, and two separate initial payments. There’s no combined-family-and-business discount built into the fee structure.

Sole proprietors sit in a different category. Because a sole proprietorship has no legal existence apart from its owner, it’s evaluated under individual rules, including potential eligibility for Low-Income Certification if the owner’s income qualifies.

Married couples who are legally separated or divorced, but who share a joint tax liability from a previously filed joint return, generally cannot file one combined offer covering both of them if their current financial situations are separate. Each spouse typically needs to submit an individual offer with its own fee and payment, reflecting their own current household income and assets.

If your household is carrying both personal tax debt and business tax debt simultaneously, expect to prepare multiple Form 656 submissions running in parallel, each with its own supporting Form 433 and its own payment package. Coordinating the timing of those submissions matters, since inconsistent financial disclosures between a personal offer and a business offer filed weeks apart can raise questions during IRS review.

Filing and Submission: Mail vs. Online, and Where to Find Official Instructions

The current mailing addresses for Form 656 change periodically based on your state and whether you’re including a payment, so don’t rely on an address from an old printout or a bookmarked page. Always pull the current version directly from the Form 656 and Form 656-B PDFs on IRS.gov before you mail anything.

Filing through your Individual Online Account carries real procedural advantages over paper mail. The system walks you through the calculations for your reasonable collection potential, processes your electronic payment in the same session, and eliminates the handwriting and math errors that account for a meaningful share of returned paper offers. If you’re an individual filer without complex business holdings, this is usually the cleaner path.

For anyone mailing a packet instead, confirm you’ve included every one of these before sealing the envelope:

  • Completed Form 656 with all sections filled out, signed, and dated.
  • Separate application fee payment ($205, unless Low-Income Certification applies).
  • Separate initial payment (20% lump-sum or first periodic installment).
  • Completed Form 433-A (OIC) for individuals or Form 433-B (OIC) for businesses.
  • Supporting documentation: recent pay stubs, bank statements, and asset valuations as required by the 433 form instructions.

Forms and thresholds get revised periodically, so check IRS.gov for the current version before you print anything. A packet built on an outdated form revision is a common, entirely avoidable reason for a return.

Expert Practical Tips From Joe Mastriano, CPA, on the Payment Portion of an OIC

After decades of watching offers succeed and fail on paperwork details rather than financial merit, a few patterns stand out consistently.

First, verify your filing category before you touch the payment section. Are you filing as an individual, a sole proprietor, or a separate business entity? That decision drives which 433 form you need and whether Low-Income Certification is even on the table. Getting this wrong at the start cascades into every payment calculation that follows.

Second, and I can’t stress this enough: never combine your application fee and your initial payment onto a single check or money order. The IRS requires them as separate instruments, and a combined payment is one of the more common triggers for a returned packet, even when the total dollar amount is correct.

Third, document everything electronic. Your EFTPS confirmation number, your IOLA submission receipt, your certified mail tracking number, all of it belongs in one file, dated and organized, before you consider the submission complete.

A quick pre-submission checklist worth running every time:

  • Confirmed individual vs. business filing status and matching 433 form.
  • Application fee and initial payment sent as two distinct instruments.
  • Electronic transfer confirmation numbers recorded and saved.
  • Proof of mailing or online submission retained separately from the packet itself.
  • Low-Income Certification eligibility checked and documented, even if you don’t ultimately claim it.

Pro Tip: If your case involves multiple tax years, prior liens, or an active levy alongside the OIC, get a professional to review your numbers before you submit. A miscalculated reasonable collection potential wastes both your $205 fee and months of processing time, and assistance with Form 433 preparation tends to catch these errors before they cost you anything.

Complex situations, multiple business entities, prior collection actions, or disputed liability alongside a genuine ability-to-pay question, are exactly where professional representation earns its cost. The financial disclosure requirements in an OIC are unforgiving of small inconsistencies, and a representative who has assembled hundreds of these packets catches the details a first-time filer misses.

What the Payment Rules Actually Reveal About the OIC Process

The conventional advice on this topic treats the $205 fee as a footnote, a small administrative cost overshadowed by the bigger question of whether the IRS will accept your offer amount. That’s backwards. The payment mechanics are the first filter the IRS applies, and they reject packets on payment technicalities long before anyone evaluates your financial hardship.

What’s underrated here is the separate-instrument rule. It sounds like bureaucratic pedantry, but it exists because the IRS routes application fees and offer payments through different internal systems. Combine them, and you’re not being efficient. You’re creating a mismatch that flags your file for return.

My honest read: taxpayers should treat the payment section of Form 656 with the same seriousness they treat the financial disclosures on Form 433. Prioritize getting the fee, the initial payment, and the documentation exactly right before you spend another hour refining your settlement number. A perfectly calculated offer amount attached to an incomplete payment package never gets read.
