Buying a business or using a §1031 exchange? Tax strategies explained.

Whether you are a tax professional guiding clients or an individual considering a major investment, understanding the tax implications of buying a business or engaging in a like-kind exchange is essential.

Both scenarios can have significant tax consequences, and the right planning can mean the difference between a tax-efficient transaction and an unexpected tax bill.

Why purchase price allocation matters when buying a business

When you buy a business, you are not just acquiring a single asset. You are purchasing a collection of assets, each with its own tax treatment. The IRS requires that the purchase price be allocated among the various assets acquired, such as land, buildings, equipment, inventory and intangible assets like goodwill or trademarks. This allocation is critical because it determines your basis in each asset, which in turn affects your future depreciation deductions and the gain or loss you’ll recognize if you later sell those assets.

Understanding Form 8594 and the residual method of purchase price allocation

The IRS mandates the use of the “residual method” for allocating the purchase price in a business acquisition. Here’s how it works:

1. Classify the assets into categories, such as cash, securities, inventory, tangible property and intangibles
2. Allocate the purchase price to cash and cash equivalents, then to other assets in a specific order, with any remaining amount allocated to goodwill and going concern value.
3. Report the allocation using Form 8594, Asset Acquisition Statement, which both buyer and seller must file with their tax returns.

This allocation is not just a paperwork exercise. It directly impacts your tax deductions. For example, amounts allocated to inventory are deductible as cost of goods sold when the inventory is sold, while amounts allocated to depreciable property are recovered over time through depreciation deductions. Goodwill and certain other intangibles are amortized over 15 years under §197.

Depreciation rules and §179 for acquired tangible property

If you acquire tangible property as part of the business purchase, you may be able to claim depreciation deductions or even elect to expense certain assets under §179, subject to annual limits. The maximum §179 deduction for 2025 is $1,220,000, reduced dollar-for-dollar if the total cost of qualifying property placed in service exceeds $3,050,000.

Watch out for liabilities

If you assume any liabilities as part of the purchase, these are generally included in your basis in the assets. However, the specific tax treatment can vary, so it’s important to review the purchase agreement.

Like-kind exchanges

A like-kind exchange, governed by §1031, allows you to defer recognition of gain (and the associated tax) when you exchange real property held for business or investment for other real property of a like kind. This powerful tool can help you grow your investment property without triggering immediate tax liability.

What qualifies as like-kind?

Under current law, only real property qualifies for like-kind exchange treatment. This means you can exchange an apartment building for a warehouse, raw land for a shopping center, or a rental house for an office building, as long as both properties are held for business or investment purposes. Personal property such as equipment, vehicles or artwork no longer qualify for like-kind exchange treatment after the tax law changed in 2017.

Requirements for §1031

1. Both properties must be held for business or investment, not for personal use or primarily for sale (no flipping houses).
2. The properties must be of like-kind, meaning they are of the same nature or character, even if they differ in grade or quality, such as a rental house for land. They are both real properties.
3. Strict timelines apply. Replacement property must be identified within 45 days of transferring the relinquished property, and the exchange must be completed within 180 days. This is very important for the §1031 to apply.

Related party rules and international rules

All like-kind exchanges must be reported on Form 8824, Like-Kind Exchanges, which details the properties exchanged, the timeline and the calculation of any recognized gain.

Practical tips for taxpayers and professionals

• Plan ahead. The rules for both business purchases and like-kind exchanges are complex. Early planning with a tax professional can help you maximize tax benefits and avoid costly mistakes.
• Document everything. Keep detailed records of purchase agreements, asset allocations and exchange documentation.
• Watch the timelines. Missing a deadline in a like-kind exchange can result in immediate tax liability.
• Consider state tax implications. Some states do not conform to federal like-kind exchange rules.

Buying a business or engaging in a like-kind exchange can be a smart way to grow your wealth or your client’s investment, but the tax rules are intricate. By understanding the basics, working with qualified professionals and keeping good records, taxpayers can make the most of these opportunities and avoid unpleasant surprises at tax time.
