Due diligence, legal and accounting work on the acquisition, the government charges published in the applicable fee schedules, and the working capital the business needs to keep operating after closing.
Budget the business, not just the application
The government charges associated with this category are small relative to the transaction and should be confirmed against the current published schedules at the time they apply. The meaningful costs sit in the deal.
Independent valuation and due diligence on a contracting business, legal work on the purchase agreement and the ownership structure, accounting review of the seller's records, and any environmental or licensing checks the trade requires are all real expenses incurred before the outcome is known. Beyond closing, the business needs enough working capital to trade through a first season, and an investment that consumes every available dollar leaves nothing to answer the question of whether the enterprise can operate as more than a marginal one.
