title: How Do You Calculate Basis for a 1031 Exchange?
description: Calculating the cost basis for a 1031 exchange is similar to calculating the cost basis on the sale of a single home up to a point. The main difference is that the property you’re exchanging into (i.e., the acquired property) must be factored into the overall exchange’s cost basis. In this article, we’ll go through the steps involved to find this basis.

# How Do You Calculate Basis for a 1031 Exchange?

Posted May 9, 2024

![](https://www.realized1031.com/hubfs/calculatetaxiStock-1177540747.jpg)

When discussing 1031 exchanges, the concept of 'basis' becomes crucial. But what does it mean in the context of a[ 1031 exchange](https://www.realized1031.com/1031-exchange)? Essentially, the basis of the replacement property acquired in a 1031 exchange is the same as the basis of the relinquished property, subject to certain adjustments. This basis carries over from your old property to your new one, effectively preserving the deferred gain for potential recognition in the future. It's this ability to defer capital gains taxes through basis transfer that makes 1031 exchanges such a powerful tool for real estate investors.

### What is basis?

Basis is the amount a property is worth for tax purposes. The basis changes over time and can be adjusted, making the concept more confusing. When you buy a property, the price you pay is the starting basis. However, the cost basis also includes acquisition costs, such as title insurance, appraisal, and legal and escrow fees.

However, the cost, or starting basis, may increase or decrease over time. If you make capital improvements to the asset, the money spent on those improvements increases the basis. For example, suppose you bought a rental property for $400,000 and had acquisition costs of $40,000 for a cost basis of $440,000. Then you remodel the units and replace the roof at a total cost of $100,000. Now your adjusted basis is $540,000.

Your basis may also decrease. Typically, basis reductions are due to depreciation deductions but may also come from losses like casualty and theft. With the $400,000 value, you can deduct $14,545 annually for depreciation. If you held this rental property for three years, you reduce the basis by the claimed depreciation of $43,635 for an adjusted cost basis of $496,635.

### Is the realized amount different from the basis?

Yes. The realized amount for the relinquished property is the sales price minus any costs of the sale. If the property sells for $700,000 net, that is the realized amount. The realized amount minus the adjusted basis is $203,365.

### What is the basis for the new property?

Calculating the basis for the new (replacement) property in a 1031 exchange is simple--the purchase price plus the commission paid. The basis for the new asset must be equal to or greater than the relinquished asset for a successful 1031 exchange. If the purchase price of the replacement property is less than the adjusted basis of the relinquished property, the 1031 will have a boot that is subject to capital gains taxes.

### How does a 1031 exchange affect the basis in the future?

The basis for the new property will include the taxes deferred in the exchange. Remember that the adjusted basis will decrease when depreciation deductions are taken, and deferred taxes are also deductions from the cost basis. Suppose the investor continues to execute sequential 1031 exchanges until distributing the final asset to an heir. In that case, the heir receives the property at a stepped-up value, and the deferred taxes are eliminated.

*Note: The depreciation amount would change depending on when the improvements were made, as those improvements would change the adjusted basis. This is an illustration.

Costs associated with a 1031 transaction may impact investor's returns and may outweigh the tax benefits. An unfavorable tax ruling may cancel deferral of capital gains and result in immediate tax liabilities.

Investing in alternative assets involves higher risks than traditional investments and is suitable only for sophisticated investors. Alternative investments are often sold by prospectus that discloses all risks, fees, and expenses. They are not tax efficient and an investor should consult with his/her tax advisor prior to investing. Alternative investments have higher fees than traditional investments and they may also be highly leveraged and engage in speculative investment techniques, which can magnify the potential for investment loss or gain and should not be deemed a complete investment program. The value of the investment may fall as well as rise and investors may get back less than they invested.
