1031 Exchange Bookkeeping: What Your Accountant Needs Before the 45-Day Clock Runs Out

A 1031 exchange lets a real estate investor defer tax on the gain from selling an investment property by reinvesting in another one. The deferral is a tax matter, handled by your qualified intermediary and CPA. But whether it holds up depends heavily on the bookkeeping: the relinquished property's books have to be closed correctly, basis and depreciation have to be known, every dollar of the exchange has to be traceable, and the replacement property has to be set up with the right opening numbers.

The clock is what makes this hard. You have 45 days from the sale to identify replacement property and 180 days to close on it, or until your tax return due date including extensions, if that comes first. There is no time to rebuild a year of books in the middle of that window.

What Does Your Accountant Need Before the Sale Closes?

Ideally, this is ready before the relinquished property is even listed.

• Up-to-date books for the property, reconciled through the most recent month end
• Original purchase settlement statement, to establish the starting basis
• Capital improvement records since purchase, with invoices
• Depreciation schedules from prior tax returns
• Any prior 1031 exchanges that created carryover basis in this property
• Loan statements showing the current mortgage balance
• Lease files and the security deposit register, since deposits transfer to the buyer
• Entity documents showing exactly which person or entity holds title

The title-holding detail matters. Generally the same taxpayer that sells the relinquished property must acquire the replacement property. If a property is in an LLC, the replacement usually needs to be acquired by that same taxpayer, so make sure everyone knows who that is before the sale.

How Do You Close the Relinquished Property's Books?

On the sale date, the property's books need a clean cutoff:

1. 1Record all income and expenses through the closing date, including prorated rent and taxes from the settlement statement.
2. 2Record the sale from the settlement statement: gross sale price, closing costs, prorations, loan payoff and the net proceeds sent to the qualified intermediary.
3. 3Transfer security deposits to the buyer as shown on the settlement statement, and clear the deposit liability.
4. 4Remove the property's fixed assets and accumulated depreciation from the balance sheet.
5. 5Record funds held by the qualified intermediary as an asset, not as cash you control. You must not have access to the proceeds during the exchange.
6. 6Final tenant and vendor reconciliation: refund or transfer any prepaid rent, pay final vendor bills and close utility accounts.

A common error is recording the exchange proceeds as if they were deposited in the investor's own account. The money should sit with the intermediary, and the books should show that.

What Should Be Tracked During the 45-Day and 180-Day Periods?

Put these dates in a shared calendar with reminders well in advance. The deadlines are strict.

What Is Boot, and How Does Bookkeeping Help Avoid It?

Boot is anything you receive in the exchange that is not like-kind real property. It is generally taxable to the extent of your gain. Common sources:

• Cash boot: proceeds you receive or that are used for non-qualifying costs.
• Mortgage boot: the replacement property has less debt than the relinquished property, and you do not make up the difference with additional cash.
• Non-qualifying costs paid from exchange funds, such as some loan fees or prorated rent credits.

Good books make boot visible. If every item on both settlement statements is recorded and categorized, your CPA can quickly see which costs are qualifying exchange expenses and which are not.

A simple example:

The investor bought more property with more debt and reinvested all equity plus $100,000 of new cash, so there is no cash or mortgage boot in this simplified example. If the investor had instead bought a $1,100,000 property with $400,000 of debt, reinvesting the same $700,000 of equity, the $100,000 drop in debt would be debt relief that could be taxable as mortgage boot.

How Is the Exchange Reported?

The exchange is reported on Form 8824, filed with your tax return for the year the relinquished property was transferred. Your CPA will need:

• Both settlement statements
• Description and dates for both properties
• The identification notice
• The qualified intermediary's exchange statement
• Adjusted basis of the relinquished property
• Any boot received or paid

How Should the Replacement Property Be Set Up?

The replacement property generally takes a carryover basis from the relinquished property, adjusted for additional cash invested, new debt and boot. Depreciation does not reset to zero: part of the basis typically continues on the old depreciation schedule, and any excess basis is depreciated as new property.

For the books:

1. 1Record the purchase from the settlement statement.
2. 2Record the basis as your CPA calculates it, with carryover and new basis separated.
3. 3Set up the replacement property's tenant ledgers, deposits and leases from the seller's records.
4. 4Start monthly accounting from the closing date.

If you plan to use cost segregation on the replacement property, tell your CPA early, because it interacts with how the carryover basis is allocated.
