Key takeaways
- Purchase price allocation (PPA) is the process of assigning the price you paid for a business to its individual assets, liabilities, and goodwill so your books reflect what you actually bought.
- PPA is required under US and international accounting standards whenever you acquire a business, and it directly affects your tax deductions, depreciation schedules, and financial reporting.
- The process involves 3 steps: identifying and valuing net assets at fair value, recording any write-ups or write-downs, and calculating goodwill as the remaining difference.
- Working with a qualified accountant or valuation expert is essential because PPA requires professional judgment and must comply with strict accounting standards.
What is purchase price allocation?
If you've recently bought a business or you're planning to, purchase price allocation is one of the first accounting steps you'll need to tackle.
Purchase price allocation (PPA) is the process of assigning the total purchase price of an acquired business to its individual assets and liabilities at fair value. Your accountant breaks down the lump sum you paid into specific categories: tangible assets like equipment and inventory, intangible assets like customer relationships and patents, liabilities like outstanding debts, and goodwill for any remaining value.
The goal is to make sure your balance sheet accurately reflects what you bought and what each piece is worth. Without PPA, your financial records would just show a single large payment with no detail behind it.
Why purchase price allocation matters
Understanding why purchase price allocation matters can help you see it as more than just a compliance exercise. It's a tool that gives you clarity on your investment and shapes your financial strategy from day one.
Financial clarity
PPA gives you a detailed picture of exactly what you paid for. Instead of a single line item on your balance sheet, you'll see the fair value of each asset and liability. This helps you understand whether you paid a premium for the business and where that value sits.
Tax benefits and depreciation
How you allocate the purchase price directly affects your tax deductions. Tangible assets can be depreciated over their useful lives, and certain intangible assets can be amortized. A well-executed PPA can reduce your tax burden in the years following the acquisition.
Strategic planning
Knowing the fair value of what you acquired helps you make smarter decisions about upgrades, expansions, and operations. If you discover that a key piece of equipment is near the end of its useful life, you can plan for replacement costs early.
Regulatory compliance
How purchase price allocation works
Purchase price allocation follows a structured process that your accountant or valuation expert will lead. Here's how the 3 main steps work in practice.
1. Identify and value net identifiable assets
The first step is to catalog every asset and liability the acquired business holds. This includes tangible assets like property, vehicles, and inventory, as well as intangible assets like trademarks, customer lists, and proprietary technology.
Each item gets assigned a fair value, which is what it would sell for in an open market transaction. A valuation expert typically handles this, using approved methods like market comparisons, income-based approaches, or cost-based calculations. The total of all asset values minus all liabilities gives you the net identifiable assets.
2. Record write-ups or write-downs
The fair values determined in step 1 often differ from the amounts on the seller's books. When an asset's fair value is higher than its book value, that's a write-up. When it's lower, that's a write-down.
For example, a piece of commercial property might be carried on the seller's balance sheet at $200,000 but appraised at $280,000. You'd record a write-up of $80,000. These adjustments are accounting entries only: no cash changes hands. They ensure your balance sheet reflects current market values rather than the seller's historical costs.
3. Calculate goodwill
After you've assigned fair values to all identifiable assets and liabilities, any remaining purchase price is recorded as goodwill. Goodwill represents the premium you paid above the net fair value of identifiable assets. It typically reflects things like brand reputation, loyal customer base, and skilled employees.
You have up to 12 months after the acquisition date (the measurement period) to finalize your PPA. During this time, you can adjust fair values as you gather more information. After that window closes, the allocation is locked in. You can find accounting professionals experienced in PPA through the Xero advisor directory.
Key components of purchase price allocation
A thorough purchase price allocation breaks the acquisition down into several distinct components. Understanding each one helps you see where your money went.
Net identifiable assets
Net identifiable assets are everything the acquired business owns minus everything it owes. This includes physical property, cash, receivables, inventory, and any debts or obligations. Only assets and liabilities that can be separately identified and measured qualify.
Fair value adjustments
Fair value adjustments bring the seller's book values in line with current market values. These adjustments can increase or decrease the recorded value of individual assets and liabilities. They also create deferred tax assets or liabilities, because the tax basis of an asset may differ from its newly assigned fair value.
Intangible assets
Intangible assets are non-physical assets that have measurable value. Common examples in a small business acquisition include customer relationships, trade names, non-compete agreements, proprietary software, and patents. Under accounting standards, you must separately identify and value each intangible asset rather than lumping them together.
Goodwill
Goodwill is the residual: the amount left over after you've allocated the purchase price to all identifiable assets and liabilities. It captures value that can't be tied to a specific asset, like a strong reputation or established market position. Goodwill isn't amortized under US GAAP; instead, it's tested for impairment annually.
Purchase price allocation example
Seeing purchase price allocation in action makes it easier to understand. Here's a practical example using a small business acquisition.
Let's say you buy a landscaping business for $500,000. Your accountant and a valuation expert work through the PPA process and identify the following.
Tangible assets:
- Workshop: $329,000
- Truck: $25,000
- Trailer: $8,000
- Mower (1): $3,000
- Mowers (2): $2,000 each
- Miscellaneous tools: $1,000
Total tangible assets: $370,000
Liabilities:
- Warranty obligations to existing customers: $20,000
Net identifiable assets: $370,000 - $20,000 = $350,000
Goodwill calculation: $500,000 (purchase price) - $350,000 (net identifiable assets) = $150,000
The $150,000 in goodwill reflects the value of the business's reputation, customer base, and other intangible qualities that made it worth more than the sum of its parts. All of these values go onto your balance sheet, giving you a clear picture of what you acquired.

Stock purchase vs asset purchase
The structure of your acquisition affects how purchase price allocation works. There are 2 main deal types, and each has different implications for your books and taxes.
Stock purchase
In a stock purchase, you buy the seller's ownership shares (or membership interests in an LLC). You take over the entire business entity, including all its assets, liabilities, contracts, and legal obligations. From an accounting perspective, you'll still complete PPA to record the assets and liabilities at fair value on your consolidated balance sheet.
The tax treatment of a stock purchase can be less favorable for buyers, because you generally inherit the seller's existing tax basis in the assets. That means you may not get the benefit of higher depreciation or amortization deductions. However, stock purchases are often simpler to execute because contracts and licenses stay with the entity.
Asset purchase
In an asset purchase, you buy specific assets and assume specific liabilities rather than taking over the entire entity. You choose which assets you want and which liabilities you're willing to take on. This structure is more common in small business acquisitions.
Asset purchases are usually more tax-friendly for buyers. You get a "stepped-up" tax basis in the purchased assets, which means higher depreciation and amortization deductions in future years. The PPA process is essentially the same, but the tax benefits can be significant. Talk to your accountant about which structure makes more sense for your situation.
Accounting standards for purchase price allocation
Purchase price allocation is both best practice and a formal requirement under accounting standards. Knowing which rules apply helps you and your accountant get the process right.
ASC 805 (US GAAP)
If your business follows US GAAP, ASC 805 (Business Combinations) sets the rules for PPA. It requires you to recognize all identifiable assets and liabilities at fair value on the acquisition date. Any excess purchase price is recorded as goodwill. ASC 805 also requires detailed disclosures about the acquisition in your financial statements.
IFRS 3 (International standards)
IFRS 3 (Business Combinations) applies similar principles for businesses that report under international standards. Like ASC 805, it requires fair value measurement and goodwill recognition. The main differences between the 2 standards are in specific measurement details, but the overall PPA framework is consistent.
The measurement period
Both standards allow a measurement period of up to 12 months after the acquisition date. During this time, you can adjust the initial PPA as new information about asset values or liabilities comes to light. Once the measurement period ends, adjustments are no longer permitted, and the allocation is final.
Goodwill impairment testing
After PPA is complete, goodwill doesn't get depreciated or amortized under US GAAP. Instead, it's subject to annual impairment testing. If the value of the acquired business drops below the carrying amount on your books, you may need to write down goodwill.

FAQs on purchase price allocation
Here are some frequently asked questions about purchase price allocation to help you navigate the process.
When is purchase price allocation required?
PPA is required whenever one business acquires control of another, regardless of size. Both US GAAP (ASC 805) and IFRS 3 mandate it for all business combinations, including small business acquisitions.
Who performs purchase price allocation?
Your accountant typically leads the PPA process, often with support from a third-party valuation specialist. The valuation expert provides independent fair value estimates for complex assets like intangible property and real estate.
What happens if the purchase price is less than net assets?
When you pay less than the fair value of net identifiable assets, it's called a bargain purchase. Under both ASC 805 and IFRS 3, you recognize the difference as a gain on your income statement in the period of acquisition.
How long does the purchase price allocation process take?
Most PPAs are finalized within 3 to 6 months, though accounting standards allow up to 12 months. The timeline depends on the complexity of the business and how quickly asset valuations can be completed.
Can you amend a purchase price allocation after it's finalized?
Once the 12-month measurement period closes, the PPA is final. However, if you discover errors in the original allocation, you may need to restate prior financial statements, which is why getting it right the first time matters.
