Schedule C Substantiation

Substantiate self-employed income and expenses with the records you actually have

A record-first system for substantiating business income and expenses without inventing documents or mixing personal and business activity.

Schedule C examinations usually come down to business purpose and separation. This kit helps you reconstruct income from deposits and platform reports, tie expenses to their business reason, and present mileage, home office and equipment records in a form a reviewer can follow.

Why this is hard

Income reconciliation

Deposits, 1099s and platform summaries rarely match line for line without an explanation.

Business purpose

An expense needs a documented reason, not just a receipt.

Mixed personal and business use

Vehicles, phones and home space need a defensible allocation method.

Missing paperwork

There are honest ways to reconstruct records — and ways that create new problems.

What is inside

  • Reconcile reported income against deposits, 1099s and platform reports
  • Document business purpose for each expense category
  • Organize mileage, home office and asset records with a stated method
  • Present reconstructed records honestly, with their basis explained

Frequently asked questions

What if I never kept a mileage log?

The kit explains how to assemble the best available support from calendars, invoices and service records, and how to describe what you have accurately.

Does this apply to gig platform income?

Yes. Platform earnings summaries and payout records are covered in the income reconciliation section.

Is this tax or legal advice?

No. The kit is an educational template. It does not create a client relationship and does not replace a CPA, enrolled agent or tax attorney. For complex cases, consider professional help or a Low Income Taxpayer Clinic.

How do I get the file after I buy?

Checkout is handled by Gumroad, which emails you a download link right after purchase.
