First determine whether the same cost actually reached the return twice. Reconcile book expense, fixed-asset basis and tax adjustments before choosing the correction procedure for each affected year.

A specific business-owner situation

An equipment invoice appears in repairs expense and the depreciation schedule. The preparer may have added back the book expense, or both deductions may have been claimed. The filed workpaper matters more than the ledger alone.

Illustrative example, not a client result.

What to establish before filing

  1. Trace the invoice through the filed return.
  2. Separate factual duplication from an adopted depreciation method.
  3. Review affected years, basis and correction procedures.

Which fact changes the answer?

A correct tax add-back means a book duplication may not have become a tax duplication. Confirm the actual filed result before assuming an amendment or method change is necessary.

A mistake to avoid

Removing the asset from the books without reviewing prior deductions can leave both tax basis and future depreciation wrong.

Records that support the decision

  • Invoice.
  • General ledger.
  • Depreciation schedules.
  • Book-to-tax reconciliation and returns.

The decision to document

Request a documented correction map and a single supported remaining basis. Reconcile later sale or depreciation calculations to that corrected history.
