Your CPA's Role in a 1031 Exchange: Taxes, Basis, and Closing Records

By Jerry Baker

Your CPA helps determine whether a 1031 exchange fits your tax situation, what you need to reinvest, and how to report the result. That work starts before the sale and continues after you buy the replacement property. This guide explains the numbers, records, and decisions I would want your tax adviser to review before an exchange becomes a closing-day scramble.

Start with the tax question before shopping for property

An exchange is a tax tool. The replacement property is an investment. Both need to make sense, and they call for different kinds of review. A property can qualify for an exchange while being a poor fit for your cash needs. A sound investment can also fail to solve a problem with your sale.

I would bring your CPA into the discussion while the sale is still being planned. Ask what tax would arise from a regular sale, what an exchange might defer, and which facts could change the answer. It is much easier to work with those answers before money moves.

Federal exchange rules generally cover real estate held for business or investment. They do not cover every asset or every reason for owning a property. Your CPA should review your actual use, ownership, and intended replacement. IRS Form 8824 instructions explain both the qualifying scope and important exclusions. [1]

That review may confirm your plan, narrow it, or show that another path deserves a look. The useful answer is the one supported by your facts, even when it is different from the answer you hoped to hear.

Agree on what the CPA will do

Your CPA may prepare your annual return without handling each tax question during an exchange. Ask what the work covers, when it will be done, what it costs, and whom to call. If you need a specialist, find that person early.

I would request three clear deliverables: an estimate before the sale, a review of the proposed replacement numbers, and a final record after closing. The estimate helps you choose a direction. The review tests the actual transaction. The final record supports reporting and future decisions.

Also decide who will answer legal questions about ownership changes, contracts, and trust terms. Your CPA, attorney, qualified intermediary, and investment professional have different roles. Some people hold more than one credential, but that does not erase the need to define the assignment.

A short contact list can prevent a long delay. Name the person responsible for each open question, state what document they need, and give them a realistic response date. “The team is handling it” is not very useful when no one knows who has the file.

Rebuild adjusted basis from records

Tax basis is not your property's market value or the balance on its loan. It usually begins with how you acquired the property, then changes over time. Improvements, depreciation, prior exchanges, and other events can affect it. IRS Publication 551 explains these adjustments. [2]

Gather the original closing statement, later capital-improvement records, prior depreciation schedules, and any earlier exchange returns. Include records of gifts, inheritance, ownership changes, casualty events, and other facts that may affect basis. Let the CPA decide which rules apply.

A common problem is a gap between what the owner remembers spending and what the tax records show. A roof may have been capitalized, expensed, or partly replaced. Do not add the same cost to basis again simply because you find its invoice in a different folder.

Check depreciation with care. Basis generally reflects depreciation allowed or allowable. In plain terms, that includes some deductions you could have taken, not just those you claimed. Missing a deduction does not always preserve basis. Ask the CPA how to fix a record problem. A guess about your old deductions is a poor starting point for a new tax plan. [2]

Separate value, equity, and gain

These three numbers often get mixed together. The property's value is what is being transferred. Equity is the value left after debt and relevant costs. Tax gain depends on amount realized and adjusted basis. Paying off a mortgage affects cash, but does not generally subtract the loan balance from taxable gain.

Consider a hypothetical sale for $1.8 million. Assume $90,000 of selling costs that the CPA confirms reduce amount realized, a $660,000 loan payoff, and $540,000 of adjusted basis. The simplified calculations are:

Planning measureCalculationAmount
Net sale value after assumed costs$1,800,000 − $90,000$1,710,000
Cash equity after loan payoff$1,710,000 − $660,000$1,050,000
Realized gain before other adjustments$1,710,000 − $540,000$1,170,000

The gain is larger than the cash equity in this example. That is possible because the two measures answer different questions. A tax estimate based on the $1.05 million equity alone would start with the wrong figure.

This illustration leaves out mixed-use allocations, personal property, credits, and special recapture issues. Your CPA must classify the actual amounts. Publication 544 and Form 8824 provide the reporting framework; a quick equity calculation does not replace it. [3] [1]

Estimate tax by category, not one headline rate

Ask the CPA to show how the gain is divided among the applicable tax categories. Depending on the facts, those can include ordinary-income recapture, unrecaptured Section 1250 gain, and other gain. Prior losses and the rest of your return may also matter.

Unrecaptured Section 1250 gain has a maximum federal rate of 25%. That is not a flat extra tax to add to a 20% capital-gain rate on the same dollars. Nor does it mean every dollar associated with depreciation is always taxed at 25%. The category and the taxpayer's calculation control. [4]

The 3.8% net investment income tax has a separate test for individuals. First, find your net investment income. Then find how far your modified adjusted gross income is above the threshold for your filing status. The tax generally uses the smaller of those two amounts. It does not apply to every dollar of every real estate sale. [5]

I would want the estimate dated and tied to a tax year, filing status, income assumptions, and state analysis. A useful estimate explains what is known, what is assumed, and which changes require it to be updated.

Compare full deferral with a partial exchange

Full deferral is not the only possible goal. You may need cash for another purpose or prefer less real estate exposure. Ask the CPA to compare a regular sale, a fully qualifying exchange, and a partial exchange using the same starting facts.

Money or nonqualifying property received can create recognized gain, often called boot. Net debt relief also matters. The Form 8824 instructions work through liabilities, additional cash, exchange expenses, realized gain, and special recapture rules. The result is more detailed than “buy something for the same price.” [1]

Using the earlier numbers, a replacement costing $1.71 million could be funded with $1.05 million of exchange equity, $460,000 of new debt, and $200,000 of outside cash. That funding adds up. Whether the full transaction qualifies still depends on the property, expenses, documentation, and other rules.

Do not reverse that example into a promise that more borrowing lets you withdraw exchange cash without tax. Extra cash can address a debt shortfall, but debt and cash offsets are not interchangeable in every direction. Have the CPA model the actual money flows before you approve them.

Line up the legal owner and the tax owner

Send the CPA the deed and ownership documents before opening replacement accounts. A familiar family name on a file does not establish which taxpayer owns the asset. An individual, partnership, corporation, trust, and disregarded entity can have different tax treatment.

A domestic single-member LLC is generally disregarded for federal income-tax purposes unless it elects corporate treatment. That does not mean every LLC is disregarded, or that its legal identity disappears for every purpose. The IRS distinguishes income-tax treatment from certain employment and excise-tax rules. [6]

Ask the CPA and attorney to confirm how the selling owner connects to the proposed acquiring owner. If partners want different outcomes, raise that problem before the sale. A last-minute deed change can raise issues that a new bank account will not solve.

Likewise, a partnership interest is generally not direct replacement real estate under Section 1031. The fact that the partnership owns buildings does not turn its units into deeds. Have the team explain any proposed structure in plain terms before using it in your exchange plan. [1]

Tell the CPA how you actually used the property. Include rental periods, personal stays, family use, vacancies, and business use. An address can have more than one tax history, especially if a former home later became a rental.

Section 121 home-sale rules and Section 1031 exchange rules are different. In some situations they must be considered together, with allocations and other limits. Form 8824 instructions address property used as a home or partly as a home. Do not assume the entire sale qualifies for both benefits. [1]

Also disclose family relationships and common ownership among buyers, sellers, and entities. Related-party rules can apply even when an intermediary sits between the parties. The CPA needs the full relationship map to identify concerns and reporting duties.

My preference is to make unusual facts visible rather than hope they will not matter. A tax adviser can evaluate a known issue. They cannot responsibly resolve a fact they are not told about until the return is due.

Do not assume the CPA can hold the proceeds

Your CPA's tax role does not make that person an eligible qualified intermediary. The rules look back two years from the date you first transfer the property you are giving up. An accountant who acted for you during that time is generally a disqualified person. There are exceptions, including certain exchange services. Tests for related parties also apply. [7]

Have the team confirm eligibility before using anyone in that role. Do not assume that a professional license, a separate bank account, or a newly created company settles it. The actual services and relationships matter.

Arrange the exchange before the sale transfers and confirm how the proceeds will move. Actual or constructive receipt can affect exchange treatment. Sending proceeds to an intermediary later does not automatically repair an earlier receipt problem. [7]

The CPA can help identify tax issues in the arrangement while the intermediary handles its agreed exchange duties. Those are complementary jobs. Neither professional should have to guess what the other agreed to do.

Put exchange dates on the tax calendar

For a typical delayed exchange, the identification period ends 45 days after the relinquished-property transfer. The exchange period generally ends at the earlier of 180 days or the due date of the taxpayer's return, including extensions. Those are separate tests that start from the same transfer. [7]

This matters for a sale late in the tax year. Ask the CPA whether you need a valid filing extension to keep the full potential exchange period. An extension does not turn 180 days into a longer period. Extra time to file is also not extra time to pay tax. [11]

Have the intermediary and CPA confirm the dates in writing. Also record earlier practical cutoffs for document review, wires, and closing. A legal deadline does not guarantee that a bank or closing office will be available at the last moment.

If a disaster or another unusual event affects the plan, ask about relief that actually applies to your taxpayer and transaction. Do not rely on a headline about an extension somewhere else. Keep the relevant notice and the reason your team believes it applies.

Review closing costs before approving the statement

The closing statement mixes items that may receive different tax treatment. A payment appearing on the statement does not make it an exchange expense. Ask the CPA to review sales costs, financing charges, prepaid items, prorations, deposits, and other adjustments separately.

Form 8824 treats qualifying exchange expenses within its calculations. Amounts used to reduce the relevant boot figure are not also added again in another part of the basis calculation. Classification and consistency matter as much as the total. [1]

Send a draft statement with time for questions. If an amount changes just before closing, identify the change and ask whether it affects the plan. Replacing an old spreadsheet with a new total without an explanation makes review harder.

After closing, reconcile the final statement against the intermediary's receipts and payments. Explain any money returned, contributed from outside, or held for a later adjustment. The tax return needs the completed transaction, not the version everyone expected a month earlier.

Build the new basis record after the purchase

A deferred gain does not vanish from the records. It generally carries into the replacement property's basis. In a simplified fully deferred exchange, replacement value less deferred gain helps illustrate the relationship, subject to the actual basis rules and adjustments.

Using the earlier example, assume a $1.71 million replacement and $1.17 million of fully deferred gain, with no further basis adjustments. The resulting basis is $540,000. Buying a more expensive asset does not create a fresh basis equal to all the dollars shown on its price tag.

Ask for the final basis by property and by relevant asset category. If you acquire several replacements, you need an allocation that connects the whole exchange to each asset. The final Form 8824 and supporting schedules should reconcile to that record. [1]

Depreciation has additional rules. Carryover and excess basis may be handled differently, and recovery periods, methods, elections, and asset types matter. Publication 946 explains the special rules for exchanged property. Do not estimate deductions by simply dividing the new purchase price by one useful life. [8]

Check state obligations and suspended losses

A federal exchange does not answer every state question. Ask which states may require a return, how each treats the exchange, and whether federal and state basis differ. Moving yourself or buying in another state does not automatically erase tax tied to the old property.

California provides a clear example. Exchanging California property for out-of-state like-kind property can require annual Form FTB 3840 reporting, regardless of residence. The instructions generally continue that reporting until the California-sourced deferred gain or loss is recognized. Keep that obligation in the permanent tax file. [9]

Ask about suspended passive losses, too. These are losses you could not yet deduct under the passive-activity rules. A qualifying exchange does not always free them for use. Selling your entire interest in an activity to an unrelated party, with all gain or loss recognized, has different rules. Your CPA needs to check the activity, current income, at-risk limits, and other facts. [10]

That review can change a comparison between selling and exchanging. Neither option should be modeled with a tax benefit it cannot use. Ask for the assumptions in both cases, including any losses expected to carry forward.

Leave with a file another adviser can understand

Before your last review call, ask the CPA to walk through the file as if someone new had to take over next year. Where did each number come from? Which figures are final? What still needs work? That is a useful test of whether the records tell the whole story.

This is my suggested way to organize the handoff, not a required IRS file format. Use your CPA's secure upload system for tax records. A neat file should make review easier without spreading your private records among people who do not need them.

Keep the signed exchange documents, identification and transmission records, closing statements, loan information, final tax forms, and basis schedules together. Add a short explanation of elections, unresolved issues, and future reporting tasks.

Ask who will review income reports and depreciation after the first year. Sponsor statements can provide useful information, but they may not know your prior exchange basis or every fact on your return. Your CPA needs those records to connect investment reporting to your situation.

If recognized gain creates a current tax bill, ask when payments are due and what cash should be reserved. Do not assume you can wait until the next return is filed. Estimated-tax requirements may apply. [4]

The goal is a clear chain from the property you sold to the assets you now own. I can help compare investments and their tradeoffs. Your CPA's tax work gives that discussion a sound set of numbers and a record that remains useful after closing.

Frequently asked questions about a CPA's role in a 1031 exchange

When should I contact my CPA?

Before the sale closes, preferably while you are still planning it. That gives the CPA time to check basis, ownership, tax exposure, and exchange requirements before money moves. Ask whether exchange planning is included in your current engagement.

Can my regular CPA serve as my qualified intermediary?

Do not assume so. Recent accounting services can make the person disqualified under the deferred-exchange rules, subject to the stated exceptions and relationship tests. Have eligibility reviewed before choosing the intermediary or moving proceeds. [7]

Is my equity the amount of gain I would pay tax on?

No. Equity reflects value after debt and relevant costs. Gain uses amount realized and adjusted basis. In the hypothetical example, cash equity is $1.05 million while realized gain is $1.17 million. Neither number can safely stand in for the other.

Do I have to take the same amount of debt on the new property?

Not necessarily. Additional outside cash may address reduced replacement debt. The CPA should reconcile proceeds, liabilities, costs, and value under the exchange rules. Do not assume extra borrowing offsets exchange cash you keep. [1]

Does an exchange give me new depreciation on the full purchase price?

No. Deferred gain affects basis, and exchanged property has special depreciation rules. Your CPA must consider carryover basis, any excess basis, asset allocations, and available elections. The price alone does not establish your deduction. [8]

Can a tax-return extension give me more than 180 days?

No. It may prevent an earlier return due date from shortening the ordinary exchange period, but it does not add days beyond the 180-day limit. Any special relief needs its own review. Confirm the actual dates before relying on them. [7]

Do I still report an exchange if no gain is currently taxable?

Generally, yes. Form 8824 reports the exchange, deferred gain, and replacement basis. Other federal or state forms may also be needed. Ask for copies of the final forms and supporting schedules rather than keeping only the closing statement. [1]

Does tax qualification mean an investment is right for me?

No. Tax treatment and investment fit are separate questions. You still need to understand income risk, fees, debt, liquidity, and control. The CPA's analysis should inform the investment decision, not replace your review of those tradeoffs.
