Failed Acquisition Costs and What Contractors Can Deduct

Episode 68 of the Construction Accounting Podcast with George Ghazarian, CPA · 6 min 28 sec · Published 5 January 2026

You spent months and real money chasing another shop — consultants, attorneys, a quality-of-earnings report — and then the deal died at the table. The checks already cleared.

Not all of that is deductible, and the bucket each expense lands in decides whether you write it off, carry it forward, or lose it outright.

The Money Goes Out Long Before a Deal Closes

Say you are tired of growing one job at a time and decide to buy an existing construction business. You spend $15,000 researching the industry, identify a target company, enter a purchase agreement, and spend another $35,000 on legal, accounting, and transaction costs. Then the deal falls apart. No closing, no business, no revenue — and the money is already spent.

The instinct is that all of it must be deductible. It is not. The answer depends on the type of cost and when you incurred it.

Bucket One: Early Investigation Costs

The first bucket is what you spend before you commit to buying a specific business: industry research, market analysis, preliminary consultant fees, early feasibility studies.

Had the deal closed, these would be treated as start-up costs — $5,000 deductible immediately, with the remaining amount amortized over 180 months, or 15 years. When the deal never closes and you never start the business, the treatment flips completely. Those costs are personal and non-deductible. No write-off. No amortization. Gone. This one surprises almost every contractor who has walked away from a purchase.

When Those Early Costs Can Still Be Recovered

Sometimes you get them back. If you later pursue another business in the same field, there is a strong argument that the original investigation costs were part of one overall business pursuit, and they can be rolled into the new start-up and amortized.

An electrical contracting company as the first target and another electrical contractor with similar operations as the second is the clean version of that argument. Pivot from construction into real estate development instead, and the original costs are lost permanently.

Bucket Two: Acquisition-Specific Costs

The bigger dollars usually sit in the second bucket. Once you pick a target, sign a purchase agreement, and begin formal due diligence, your legal, accounting, and transaction costs become capitalized acquisition costs. That covers attorney fees, CPA quality-of-earnings reports, deal structuring costs, and investment banker fees.

If the deal closes, those get capitalized into the purchase and recovered over time. If the deal fails, they become a capital loss — a much better outcome than the investigation bucket, and the reason the line between the two matters so much.

How the Capital Loss Actually Works

Because the acquisition agreement usually exists for less than one year, the loss is typically a short-term capital loss. That means you can offset capital gains with it, deduct up to $3,000 per year against ordinary income, and carry any remaining loss forward indefinitely.

So on $35,000 of failed acquisition costs, you have not lost the deduction. You have moved it into the capital loss bucket, where it comes back slowly unless you have gains to absorb it. That is a very different result from the investigation costs, which produce nothing at all.

Why Contractors Get This Wrong

Most owners lump every deal cost into one pile and assume that if the deal dies, it is all deductible. The tax code treats early investigation costs, start-up costs, and transaction costs very differently, even though they feel identical when you are writing the checks. And a CPA who does not work in construction, in acquisitions, or with failed transactions may miss the distinction entirely.

What to Nail Down Before You Start Looking

Documentation drives the outcome here more than the dollar amount does. Three things need to be clear on every invoice you pay:

• Timing — was this incurred before or after you committed to a specific target
• Purpose — general industry research, or work on this particular deal
• Scope of work — the engagement letter should make which one obvious on its face

One wrong classification can swing the tax result by tens of thousands of dollars. If you are looking at buying another business, selling your company, or sizing up a competitor, get the tax planning done before the deal starts rather than after it collapses. The IRS does not weigh how painful the failure was. It looks only at how the expenses were incurred and how they were classified.

The short version

• Early investigation costs are non-deductible if no business is ever acquired
• Start-up treatment allows $5,000 immediately and 180-month amortization
• Failed acquisition-specific costs generally become short-term capital losses
• Capital losses offset gains plus $3,000 of ordinary income per year
• Remaining capital loss carries forward indefinitely until it is used
• Engagement letters should state timing, purpose, and scope of each fee
