Reconstruction Tax™

What Late Recognition Costs

When a matter change is handled after the work is done, the cost shows up in two places: revenue written down and time spent reconstructing what happened.

The Economics

Two costs, paid after the work is done.

When a consequential change first surfaces at billing review, the firm is no longer deciding what should happen. It is reconstructing what already happened, and paying for it twice.

Realization Leakage

Write-down exposure

Revenue written down, before or after the invoice goes out, because the context behind changed work is no longer clear by the time it is billed. It reduces realization on work the firm has already performed.

Capacity Leakage

Reconstruction effort

Partner, attorney, management, and billing time spent piecing together what changed, why, and who decided. It is rarely billable, and it displaces work that would be.

The Reconstruction Tax™

Margin pressure that compounds across matters

Both costs land on the same matters. Write-downs compress margin, and reconstruction consumes the time of the people the firm most needs on client work. The combined cost of the two is the Reconstruction Tax™. Across a year of matters, it can be material.

Why It Is Growing

The pressure is building from three directions.

Late-recognized changes are not new. Three pressures are making them more costly.

Firm Economics

Scope changes reach margin and profitability

Changes in scope and additional work can affect margin, realization, and profitability, and firms are already absorbing more write-offs. BigHand’s 2026 Annual Law Firm Finance Report found that 90 percent of firms reported write-offs increased year over year.

Client Expectations

Clients are raising the bar on budgets and transparency

Corporate legal departments are placing greater emphasis on budgeting, transparency, billing discipline, and adherence to outside counsel guidelines. Requirements vary by client, but many want to understand significant changes before they appear on an invoice.

Technology

Invoice review is becoming more sophisticated

More sophisticated billing and invoice-review tools, including AI-assisted review, are increasing the ability to identify work that falls outside agreed assumptions or client requirements. A change that was never discussed with the client is more likely to be noticed, and harder to explain after the fact.
