Example Data Table

Scenario Item Example Value Meaning
Relinquished sale price $850,000.00 Gross contract value of the old investment property.
Selling expenses $45,000.00 Fees that reduce net proceeds and realized gain.
Adjusted basis $390,000.00 Tax basis after depreciation and improvements.
Debt paid off $250,000.00 Debt relief that must be offset with debt or cash.
Replacement price $920,000.00 Higher value purchase that supports full deferral.
New mortgage + added cash $377,000.00 Fully offsets debt relief and covers funding needs.
Estimated deferred gain $415,000.00 Gain postponed into the replacement basis.
Estimated replacement basis $517,000.00 Replacement value minus deferred gain, plus expenses.

Formula Used

Net Sale Proceeds = Relinquished Sale Price − Selling Expenses

Exchange Equity Available = Net Sale Proceeds − Debt Paid Off

Realized Gain = Net Sale Proceeds − Adjusted Basis

Required Exchange Proceeds = (Replacement Price + Replacement Expenses) − New Debt − Additional Cash

Estimated Cash Boot = Exchange Equity Available − Exchange Proceeds Applied, never below zero

Estimated Recognized Gain = Lesser of Realized Gain or Estimated Boot

Estimated Deferred Gain = Realized Gain − Recognized Gain

Estimated Replacement Basis = Replacement Price − Deferred Gain + Replacement Expenses

Estimated Tax = Recapture Portion × Recapture Rate + Remaining Recognized Gain × Capital Gains Rate + Recognized Gain × State Rate

This model is intentionally simplified for planning. Actual treatment can change with related parties, improvements, prorations, debt structure, partnership interests, carryover basis adjustments, recapture details, and state-specific rules.

How to Use This Calculator

  1. Enter the old property sale price, selling costs, adjusted basis, and debt being paid off.
  2. Enter the replacement property price, new financing, extra cash contribution, and replacement-side exchange expenses.
  3. Add any cash-out or non-like-kind value received as other boot.
  4. Use your expected federal capital gains, recapture, and state tax rates for a planning estimate.
  5. Add the relinquished closing date to estimate the 45-day identification deadline and 180-day completion deadline.
  6. Submit the form. Review whether value, equity, and debt replacement support full deferral or signal potential taxable boot.

Frequently Asked Questions

1) What does this calculator estimate?

It estimates net proceeds, realized gain, taxable boot, deferred gain, replacement basis, and timing targets for a common deferred real estate exchange scenario.

2) Does a higher replacement price always avoid tax?

Not always. Full deferral usually needs equal or greater replacement value and full reinvestment of exchange equity, while debt relief must be offset with new debt or added cash.

3) What is boot?

Boot is money or non-like-kind value received in the exchange. It can also arise when replacement value or debt replacement falls short.

4) Why does basis matter?

Replacement basis affects future depreciation and gain when you later sell. A larger deferred gain usually lowers the new property’s carryover-style tax basis.

5) Are the tax estimates exact?

No. The tool gives planning estimates only. Depreciation recapture, state conformity, related-party rules, closing statement items, and legal structure can materially change actual tax outcomes.

6) Can I use this for personal residences?

No. This calculator is for investment or business real property planning. Primary residences and dealer property generally follow different tax rules.

7) Why do I need the closing date?

The closing date starts the deferred exchange clock. The tool uses it to estimate the written identification deadline and the exchange completion deadline.

8) Should I still use a qualified intermediary and advisor?

Yes. Proper documentation, escrow control, deadlines, entity structure, and tax reporting are essential. This calculator supports planning, not legal or tax advice.
