Which tax years does the reporting change affect?
The December 2025 IRS instructions make Section G optional for tax years beginning before 2026 and required for years beginning after 2025, subject to exceptions. The beginning of the tax year matters; the calendar year in which a return is filed is not the same test.
Before preparing a detailed component schedule, the return preparer should determine whether an exception applies. The instructions address a qualified small business making the applicable payroll-credit election and an original-return exception that combines a $1.5 million QRE ceiling with a $50 million prior-three-year average gross-receipts ceiling. Review the precise definitions, group rules, and current instructions for the return being filed.
Being excepted from Section G does not remove the need to establish that claimed activities and expenses qualify.
List your client’s business components first.
Start with the products, processes, software, techniques, formulas, or inventions being evaluated. A project-management label may be broader or narrower than a business component. Agree on a defensible grouping and use consistent identifiers across narratives, financial schedules, and source folders.
For each component, collect its purpose, development period, technical contacts, relevant records, and expense connections. If one internal project includes several components, explain the separation. If several internal tasks relate to one component, document how they fit together.
Software components require particular care because the reporting classification can depend on the software's purpose and users. Do not infer the classification merely from the department that paid for the development.
Match expenses to components and source records.
Create working schedules that associate qualifying services, supplies, and contract research with the components being reviewed. Keep excluded amounts visible in the reconciliation. Where an employee works across components, preserve the basis used to divide the qualifying services.
The reporting instructions use an “80%/Top 50” approach and aggregate remaining components. Apply the detailed selection and group rules after the full expense inventory has been reconciled; selecting projects first can obscure costs that belong elsewhere. The form's reporting threshold is not a shortcut for deciding which research qualifies.
A practical working file has separate columns for source amount, proposed qualified amount, component, allocation basis, and reviewer questions. Keep identifiers stable when schedules are revised so the technical narrative continues to match the financial file.
Resolve reporting questions with the tax preparer.
Confirm which form revision applies, how any controlled-group rules affect reporting, and whether the return is original or amended. Required information and filing considerations should be checked for the particular situation. Avoid transferring last year's settings without revisiting these facts.
Reconcile the component totals to the expense schedules and the calculation. Check naming consistency, software categories, missing fields, and any aggregate amounts. Keep the exception analysis or reporting rationale with the workpapers so another reviewer can understand the approach.
Our client document request guide can help organize the initial collection. The study review checklist addresses the broader activity and calculation review.
