Draft the 481(a) summary for a Form 3115 filing

When a look-back KBKG study is completed, WebRun runs the 481(a) adjustment calculator, reads the net catch-up depreciation and the asset detail behind it, writes a clear summary in a Google Sheet for the Form 3115, and posts your preparer in Slack that it is ready to review and file.

In short

How do I prepare the 481(a) adjustment summary for a Form 3115?

When a look-back KBKG study is completed, WebRun runs its 481(a) adjustment calculator, reads the net catch-up depreciation and the reclassified assets, writes a clear summary in Google Sheets for the Form 3115, and posts your preparer in Slack. WebRun never files the 3115; the preparer reviews the summary and files it.

  • Every look-back study gets its 481(a) catch-up figured and summarized
  • The Form 3115 backup sits in one place, not scattered across the study
  • Preparers review and file, so nothing is submitted to the IRS unchecked

Questions, answered

Does it file the Form 3115?

No. WebRun runs the 481(a) calculation in KBKG and writes a summary for your preparer. It never files or submits the Form 3115. A preparer reviews the catch-up figure and the backup, then completes and files the form.

What does the summary include?

It includes the property, the change in accounting method, the net 481(a) catch-up amount, the tax year, and the reclassified assets by recovery-period bucket, so the preparer has both the number and the supporting detail.

Where does the catch-up amount come from?

The catch-up amount comes from KBKG's 481(a) adjustment calculator run against the completed look-back study, so it reflects the reclassifications in that study rather than a manual estimate.
