Section 351 and Section 1031 defer tax in fundamentally different transactions. Section 351 generally applies when one or more people transfer property to a corporation for its stock and, immediately afterward, those transferors control the corporation. Section 1031 generally applies when a taxpayer exchanges qualifying real property held for business or investment for other like-kind real property. It does not apply simply because property is sold and the proceeds are later reinvested.
The practical dividing line is purpose: are you capitalizing or reorganizing a corporation, or are you replacing investment or business real estate? Section 351 centers on stock consideration and immediate corporate control. Section 1031 centers on qualifying real property, like-kind status, strict deferred-exchange deadlines and keeping sale proceeds out of your possession.
What each provision is designed to do
Section 351: a contribution to a controlled corporation
Section 351 is a nonrecognition rule for incorporating a business or moving property into a corporation. The statutory rule states: “No gain or loss shall be recognized if property is transferred to a corporation by one or more persons solely in exchange for stock in such corporation and immediately after the exchange such person or persons are in control.” Control is measured under Section 368(c).
The transferor receives stock rather than cash as the normal consideration. The rule can cover a single owner contributing assets to a newly formed corporation or several people contributing property to an existing corporation, provided the transferors meet the immediate-control requirement as a group. Section 351 is not a general rollover rule for any asset sale; it is tied to a corporate transfer and the stock received.

Section 1031: a like-kind exchange of qualifying real property
Section 1031 applies to an exchange of real property held for productive use in a trade or business or for investment. The replacement property must also be held for one of those purposes, and the properties must be like-kind. Property held primarily for sale is excluded. The statute describes the rule as follows: “No gain or loss shall be recognized on the exchange of real property held for productive use in a trade or business or for investment if such real property is exchanged solely for real property of like kind which is to be held either for productive use in a trade or business or for investment.”
A 1031 exchange can be simultaneous, but many transactions are deferred: the taxpayer transfers the old property first, identifies replacement property in writing within 45 days, and receives the replacement property by the earlier of 180 days after the transfer or the due date for the taxpayer’s return, including extensions. Those deadlines are statutory, not suggested planning targets.
Section 351 and Section 1031 compared
| Issue | Section 351 | Section 1031 |
|---|---|---|
| Main use | Transfer property to a corporation for stock | Exchange business or investment real property for like-kind real property |
| Threshold test | Transferors control the corporation immediately after the exchange under Section 368(c) | Both properties are qualifying real property held for business or investment, and the exchange satisfies like-kind and timing rules |
| Normal consideration | Corporate stock | Replacement real property |
| Boot | Gain is recognized up to money plus the fair market value of other property received; no loss is recognized under Section 351(b) | Gain is generally recognized to the extent of money or other non-like-kind property received, subject to statutory limits |
| Timing | No statutory 45-day or 180-day replacement deadline for a direct contribution | Deferred exchanges require written identification within 45 days and completion by the earlier of 180 days or the return due date, including extensions |
| Basis | Corporate and shareholder basis rules require Section 351 calculations; Section 351 supplies the nonrecognition framework | Replacement basis generally starts with the relinquished property’s basis, adjusted for money, liabilities, costs and recognized gain |
| Proceeds | Stock is the expected consideration; cash or other property can trigger current gain | The taxpayer must avoid actual or constructive receipt of sale proceeds in a deferred exchange; a qualified intermediary or qualified trust is the recognized safe-harbor structure |
How a Section 351 transfer works
1. Identify the property and the corporation
List every asset being transferred, its tax basis, fair market value, liabilities and the stock to be issued. Section 351 concerns a transfer to a corporation, so the transaction documents should show the corporation as the recipient and stock as the consideration. A transfer of property directly to another person, partnership or limited liability company is not automatically a Section 351 transaction.

The tax analysis should classify each item separately rather than treating a mixed package as one undifferentiated asset. A valuation, contribution agreement, stock ledger and corporate resolutions help establish what moved and what was issued.
2. Test immediate control
Immediately after the exchange, the transferor or transferors must be in control as measured under Section 368(c). When several people contribute property, the control test is applied to the transferors as the relevant group, not merely to the person who contributed the most valuable asset. Ownership changes, prearranged sales of stock and contributions made at different times can affect whether the required control exists.
Because control is tested at the moment after the exchange, document the ownership table at closing. Show each transferor’s voting and other relevant ownership interests, the shares issued for each contribution and any rights that could alter control. A tax adviser should review side agreements before signing, because a planned disposition can change the analysis even if the corporation technically issues stock.

3. Check for money or other property
Section 351(b) limits nonrecognition when a transferor receives money or property other than the corporation’s stock. Gain is recognized up to the money plus the fair market value of the other property received. The rule does not authorize a loss deduction in the same situation; no loss is recognized under Section 351(b).
“Boot” can arise from cash paid at closing, a distribution of another asset, or consideration that is not stock. Separate the stock portion from every nonstock item in the closing statement. If the corporation assumes liabilities or the transferor receives debt relief, the liability consequences require a separate calculation; do not assume that debt relief is tax-free simply because no cash changes hands.
4. Calculate corporate and shareholder basis
Section 351 does not mean that the corporation and shareholder receive a fresh fair-market-value basis. The corporation and the transferor each have basis computations that depend on the property transferred, stock issued, money or other property received, liabilities and any gain recognized. The calculations should be prepared asset by asset, with records preserved for future sale, depreciation and distributions.
For the shareholder, the stock basis is important because it carries the deferred gain into a later stock sale or redemption. For the corporation, the asset basis affects future depreciation, amortization and gain or loss when the corporation disposes of the asset. The closing file should retain original purchase records, improvement costs, depreciation schedules and valuation support.
5. Complete the corporate documentation
- Approve the contribution and stock issuance through the corporation’s governing process.
- Prepare a written contribution or exchange agreement listing each asset, liability and class of stock.
- Transfer titles, contracts, permits and account ownership where the asset requires a formal change.
- Record the stock issued and the ownership percentages immediately after closing.
- Prepare the required tax reporting and maintain the basis schedules with the corporate books.
Illustrative Section 351 scenario
Three founders contribute equipment, intellectual property and cash to a newly formed corporation and receive only its stock. If the founders collectively satisfy the immediate-control test, the transfer can fit Section 351’s nonrecognition framework. If one founder also receives cash or a different asset, gain can be recognized up to that nonstock consideration, while a built-in loss is not recognized under Section 351(b). The corporation and founders still need separate basis schedules; the rule postpones recognition, rather than erasing the underlying gain.

1. Confirm that both properties qualify
Section 1031 is limited to real property held for productive use in a trade or business or for investment. The replacement property must be held for one of those purposes as well. Property held primarily for sale is excluded, so a dealer’s inventory cannot be converted into qualifying exchange property merely by labeling the transaction an exchange.
Like-kind describes the relationship between the real properties, not whether they are identical buildings or used in the same industry. The analysis should address the legal nature and intended holding purpose of each property. Mixed assets, personal-use portions and property held for resale should be separated before the exchange is structured.
2. Set up the deferred exchange before proceeds are available
In a deferred exchange, the taxpayer must avoid actual or constructive receipt of the sale proceeds. The IRS-recognized safe-harbor approach uses a qualified intermediary or qualified trust to hold and apply the proceeds under the exchange agreement. The taxpayer should engage the intermediary and execute the exchange documents before closing the relinquished-property sale, not after receiving the money.
The intermediary arrangement does not by itself make an exchange qualify. The properties, holding purposes, identification notice, acquisition and reporting must all satisfy Section 1031. Confirm the intermediary’s role, fee, insolvency protections, wire instructions and release conditions in writing, and verify that the arrangement matches the taxpayer’s jurisdiction and transaction documents.

The replacement property must be identified in writing within 45 days after the relinquished property is transferred. The identification must be specific enough to establish what property is intended; a vague description can create a dispute about whether the deadline was met. Calendar the deadline from the actual transfer date, account for weekends and holidays, and deliver the written identification exactly as the exchange agreement requires.
4. Acquire the replacement property by the statutory deadline
The replacement property must be received by the earlier of 180 days after the relinquished-property transfer or the due date for the taxpayer’s return, including extensions. Filing an extension can affect the return due-date component, but it does not extend the 180-day limit. Arrange inspections, financing, title work and lender approvals early enough that a last-day closing is not the only option.
- Before the relinquished-property closing, execute the exchange agreement and place the intermediary between the taxpayer and the proceeds.
- Transfer the relinquished property and document the exact transfer date.
- Within 45 days, send the written replacement-property identification to the required party.
- Keep proceeds in the exchange structure and avoid directing them to personal or business accounts.
- Close on the identified replacement property by the earlier statutory deadline.
- Retain the settlement statements, identification notice, intermediary statements and basis calculations for tax reporting.
5. Account for boot and liability changes
Receiving cash or other non-like-kind property can make part of the gain taxable. Liability changes and transaction costs also affect the computation. A taxpayer may have a qualifying exchange and still owe current tax on the nonqualifying portion. Have the intermediary, closing agent and tax adviser reconcile the sources and uses of funds before closing so that unexpected cash does not appear at settlement.

6. Carry the basis into the replacement property
The acquired property’s basis generally begins with the basis of the relinquished property, adjusted for money, liabilities, costs and recognized gain. That carryover preserves the deferred gain for a later disposition; it is not a reset to the replacement property’s market value. Keep the old property’s depreciation, improvement and acquisition records with the new property’s file.

Illustrative Section 1031 scenario
An investor transfers an apartment building held for investment and uses a qualified intermediary to acquire another investment real property. The investor identifies the replacement property in writing within 45 days and completes the acquisition within the applicable 180-day limit. If cash or other non-like-kind property is received, gain is generally recognized to that extent, while the remaining deferred portion is reflected in the replacement property’s adjusted basis.
The practical differences that determine which rule fits
Transaction purpose
Use Section 351 when the economic objective is to contribute assets to a corporation in return for corporate stock. Use Section 1031 when the objective is to dispose of one qualifying business or investment real property and acquire another. Reinvestment alone does not transform a sale into a 1031 exchange, and incorporation alone does not create a 1031 exchange.
Ownership and consideration
Section 351 changes the ownership form: the contributor owns stock and the corporation owns the contributed assets. Section 1031 generally keeps the taxpayer in an ownership position in real estate, replacing one property with another. Stock is the normal Section 351 consideration; replacement real property is the normal Section 1031 consideration.
Timing pressure
A direct Section 351 contribution has no statutory 45-day identification or 180-day acquisition period. Section 1031 deferred exchanges do. This makes advance coordination with a qualified intermediary, lender, title company and tax adviser central to a 1031 transaction, while a 351 transaction’s timing risk is more often corporate governance, valuation and control at closing.

Property scope
Section 351 can apply to property contributed to a corporation, subject to its statutory requirements. Section 1031 is confined to qualifying real property held for business or investment and excludes property held primarily for sale. An asset-by-asset classification is therefore essential when a proposed transaction includes real estate, equipment, cash, contracts or inventory.

Tax paid now versus tax deferred
Neither provision permanently eliminates built-in gain. Boot can trigger current recognition, and carryover basis preserves deferred gain for a later disposition. A projection should show the amount of gain recognized at closing, the basis transferred to the corporation or replacement property and the tax consequences of a later sale.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Common failure points and corrective steps
Calling a sale a contribution
If the taxpayer receives cash from a buyer and later contributes the cash to a corporation, that sequence is not the same as transferring property to the corporation for stock. Document the actual parties, consideration and transfer order. Have counsel review any prearranged sale of contributed assets or stock before execution.
Missing the 45-day or 180-day deadline
Late identification or late receipt of replacement property can disqualify the deferred-exchange treatment even when the investment decision was commercially reasonable. Put both dates in a written closing calendar, assign responsibility for delivery of the identification notice and maintain evidence of when the notice was sent and received.

Taking possession of exchange proceeds
Depositing sale proceeds into the taxpayer’s account or directing the intermediary to release funds for personal use can create actual or constructive receipt. Keep the proceeds within the documented exchange structure and obtain written instructions before any permitted disbursement.
Ignoring nonqualifying property
Cash, other property, property held primarily for sale and personal-use portions can produce a result different from the taxpayer’s headline plan. List each component of the transaction, classify its use and value it separately before signing the purchase or contribution agreement.
Failing to model liabilities and basis
Debt relief, assumed liabilities, transaction costs and recognized gain can alter both current tax and the basis carried forward. Reconcile the old basis, new basis, liabilities and cash on a written schedule. Do not rely solely on the settlement statement or the accounting entry.
Using incomplete records
Keep deeds, contribution agreements, stock records, exchange agreements, identification notices, intermediary statements, appraisals, improvement invoices and depreciation schedules. These documents support the nonrecognition position and make a later sale or audit easier to analyze.

- Define the objective. If the objective is corporate capitalization for stock, begin with Section 351. If it is replacement of business or investment real estate, begin with Section 1031.
- Map the assets. Identify property type, holding purpose, tax basis, fair market value, liabilities and any cash or other consideration.
- Test the threshold rule. For Section 351, analyze immediate control under Section 368(c). For Section 1031, confirm qualifying real property, like-kind status and business or investment intent.
- Model boot. Calculate the effect of money, other property and liability changes before closing.
- Plan the mechanics. Prepare corporate approvals and stock records for Section 351; engage a qualified intermediary and calendar both statutory deadlines for a deferred Section 1031 exchange.
- Prepare basis schedules. Show the basis transferred to the corporation or carried into the replacement property and identify the gain, if any, recognized currently.
- Review reporting. Have a tax professional confirm the return disclosures and retain the transaction file.
Questions to ask a tax professional
- Does the proposed transfer satisfy the immediate-control test, considering every transferor and any planned stock disposition?
- Which assets are qualifying real property, and is any portion held primarily for sale or personal use?
- What cash, other property or liability changes could be treated as boot?
- What are the exact 45-day and 180-day dates based on the anticipated closing date?
- Who will hold the proceeds, and does the qualified-intermediary arrangement prevent actual or constructive receipt?
- What basis will the corporation, shareholder or replacement-property owner report?
- Which documents must be signed before closing, and how will the transaction be reported on the applicable tax returns?
Bottom line
Section 351 is the corporate formation and contribution rule: property goes to a corporation for stock, and the transferors must control the corporation immediately afterward. Section 1031 is the like-kind real-estate exchange rule: qualifying business or investment real property is replaced with qualifying like-kind real property, with strict identification, completion and proceeds-handling requirements in a deferred exchange. Cash, other property and liability changes can create current gain under either regime, and basis generally carries deferred gain forward. Because ownership, use, documentation and timing determine the result, obtain transaction-specific tax advice before transferring property or closing a replacement purchase.
