Calculators

Offer in Compromise Calculator

This calculator estimates the minimum acceptable Offer in Compromise (OIC) amount based on IRS Form 433-A (OIC) and Form 656 methodology [^147^][^148^]. The Reasonable Collection Potential (RCP) is calculated as: Net Realizable Equity in Assets + (Monthly Disposable Income × Multiplier). For lump sum offers (paid within 5 months), use 12-month multiplier; for periodic payment offers (6-24 months), use 24-month multiplier [^147^][^149^]. Net Realizable Equity is generally 80% of fair market value minus secured loans, except cash which is valued at face value [^148^][^154^]. Allowable expenses are determined by IRS National and Local Standards, not actual expenses. The IRS accepts OICs when the offer equals or exceeds RCP and collection of full liability would create economic hardship [^148^][^151^]. Initial payment required: 20% of offer for lump sum, or first monthly installment for periodic payments. Application fee is $205 (waived for Low Income Certification). Results are estimates; consult IRS Form 656 instructions or a qualified tax professional for official calculations. OIC acceptance rate is approximately 21% for self-prepared applications [^148^].

What Is an Offer in Compromise Calculator?

An Offer in Compromise Calculator is a tool that estimates the lowest amount the IRS may accept to settle your tax debt.

It follows the same basic formula used by the IRS:

Reasonable Collection Potential (RCP) = Net Asset Value + Future Income

Your calculator uses this exact method .

In simple terms, the IRS looks at:

  • What you own (assets)
  • What you earn (income)
  • What you spend (allowable expenses)

Then it decides how much it believes it can collect from you.

How the Calculator Works (Step by Step)

Let’s break down the logic behind your calculator in plain English.

1. Monthly Disposable Income (MDI)

This is your starting point.

MDI = Monthly Income − Allowable Expenses

  • If your income is ₹5,000 and expenses are ₹4,000 → MDI = ₹1,000
  • If expenses are higher than income → MDI becomes 0 (not negative)

Your calculator ensures this by using:

Math.max(0, monthlyIncome - allowableExpenses)

This matters because the IRS only counts positive disposable income.

2. Future Income Value

Next, the IRS estimates how much you can pay over time.

This depends on your payment option:

  • Lump sum (within 5 months) → multiply MDI by 12
  • Periodic payments (6–24 months) → multiply MDI by 24

So:

  • ₹1,000 MDI × 12 = ₹12,000
  • ₹1,000 MDI × 24 = ₹24,000

This is called your future income component.

3. Net Realizable Equity (NRE)

This is the value of your assets after adjustments.

Your calculator includes:

  • Bank accounts (full value)
  • Investments (80% of value)
  • Real estate (80% minus loan balance)
  • Vehicles (80% minus loan balance)

Why 80%?

Because the IRS assumes a quick sale value, not full market value.

Example:

  • House worth ₹100,000
  • Loan = ₹70,000
  • Adjusted value = ₹80,000 − ₹70,000 = ₹10,000

Your calculator applies this rule clearly .

4. Reasonable Collection Potential (RCP)

Now everything comes together:

RCP = Net Realizable Equity + Future Income

This is the minimum offer the IRS expects.

If your RCP is:

  • ₹20,000 → You must offer at least this amount
  • Less than your total tax debt → You may qualify
  • Equal or more → IRS may reject your offer

5. Debt Forgiveness Estimate

Your calculator also shows how much debt could be reduced:

Debt Forgiveness = Total Tax Debt − RCP

Example:

  • Tax debt = ₹50,000
  • RCP = ₹20,000
  • Forgiveness = ₹30,000

It also shows the percentage forgiven.

6. Eligibility Check

The calculator gives a quick eligibility result:

  • Likely Eligible → RCP < Tax Debt
  • Full Payment Expected → RCP ≥ Tax Debt
  • Insufficient Data → Missing inputs

This mirrors how the IRS evaluates “doubt as to collectibility.”

7. Initial Payment Requirement

The calculator also estimates what you must pay upfront:

  • Lump sum → 20% of your offer
  • Payment plan → First monthly installment

This is required when submitting your OIC application.

Key Inputs Explained (What You Need to Enter)

To get accurate results, each field matters.

Income and Expenses

  • Monthly income (before tax)
  • Allowable expenses (based on IRS standards, not actual spending)

Assets

  • Bank balance (full value)
  • Investments (reduced value)
  • Property and vehicles (value minus loans)

Tax Debt

  • Total amount you owe

Small mistakes here can change your result a lot.

Example Calculation

Let’s walk through a simple case:

  • Tax debt: ₹60,000
  • Monthly income: ₹4,000
  • Expenses: ₹3,000
  • MDI: ₹1,000

Assets:

  • Bank: ₹5,000
  • Investments: ₹10,000 → ₹8,000 after 80%
  • Car equity: ₹2,000

Total NRE = ₹15,000

Future income (lump sum):

  • ₹1,000 × 12 = ₹12,000

RCP:

  • ₹15,000 + ₹12,000 = ₹27,000

Offer amount:

  • ₹27,000

Debt forgiven:

  • ₹33,000

This is the kind of output your calculator generates automatically.

Why This Calculator Is Useful

A good OIC calculator does more than give a number.

It helps you:

  • Understand if you qualify before applying
  • Avoid submitting unrealistic offers
  • Estimate how much debt can be reduced
  • Plan your finances better

It turns a complex IRS formula into something you can actually use.

Limitations You Should Know

Even though the calculator is helpful, it’s still an estimate.

Keep these points in mind:

  • The IRS may adjust your expenses
  • Asset values can be reviewed differently
  • Special situations (hardship, medical issues) matter
  • Approval is not guaranteed

Your calculator already includes a disclaimer about this , which is important.
