Action Guide: Scrub for Tax Returns

Tax returns are vital documents for underwriting and merchant cash advance evaluations. They reveal a company’s income sources, deductions, and tax obligations, providing a clear view of business performance and creditworthiness.

However, these documents are lengthy, dense, and inconsistent in structure. Reviewing them manually for accuracy and completeness often leads to missed red flags or delayed decisions.

Heron automates the scrubbing of tax returns by systematically checking, validating, and structuring the data inside. The system reads through all pages, detects missing schedules, verifies totals across forms, and flags irregularities that could affect underwriting outcomes.

It ensures that each return is complete, accurate, and ready for decision-making.

With automated scrubbing, MCA brokers and funders can move from raw document intake to decision-ready data in minutes instead of hours, reducing rework and increasing throughput.

Use Cases

  • Verify document completeness: Heron confirms that every required schedule (C, K-1, SE, etc.) is present before underwriting begins.
  • Cross-check reported figures: The system validates that totals on different forms (e.g., Schedule C income vs. Form 1040 totals) align correctly.
  • Detect inconsistencies: Heron flags mismatched figures, duplicated pages, or missing tax years.
  • Identify potential fraud: Altered totals, tampered pages, or reused attachments are detected during the scrub.
  • Highlight risk indicators: Negative taxable income or unusually high deductions trigger alerts for closer review.
  • Prepare data for write-back: Once scrubbed, clean fields are structured and ready to populate CRM or underwriting systems.

These use cases streamline financial review, helping funders make faster, more confident decisions.

Operational Impact

Scrubbing automation delivers measurable business outcomes across speed, accuracy, and scalability.

  • Speed: Heron processes complete tax return packets in seconds, eliminating long manual reviews.
  • Accuracy: Automated checks minimize human error and maintain consistent data standards.
  • Scalability: Handles large intake volumes without requiring additional staff or offshore support.
  • Auditability: Every detected issue, correction, or exception is logged for full traceability.
  • Cost savings: Teams process more deals with fewer manual hours, cutting review costs by up to 70%.

By automating tax return scrubbing, Heron helps organizations accelerate deal flow and maintain data reliability at scale.

Scrubbing Workflow in Heron

Heron’s tax return scrubbing process combines rule-based logic with AI-powered analysis.

  • Data extraction: Key values and line items are parsed automatically from tax forms and schedules.
  • Cross-form validation: Extracted data is compared across related forms to confirm consistency (e.g., Form 1120S vs. Schedule K-1 totals).
  • Completeness verification: Missing forms, pages, or years are detected and flagged.
  • Risk pattern analysis: The system identifies red flags such as negative income or repeated tax anomalies.
  • Normalization: Figures are standardized for comparison across merchants or years.
  • Ready-to-underwrite output: Clean, validated data flows directly into CRM or underwriting dashboards.

This workflow transforms unstructured tax filings into structured, decision-ready data for underwriting and compliance.

Governance and Data Accuracy

Heron’s scrubbing automation operates under strict data integrity and compliance standards.

  • SOC 2-aligned controls: All handling of financial documents meets enterprise security requirements.
  • Audit trails: Each scrub is logged with timestamps, user IDs, and detected exceptions.
  • Traceable validation: Every scrubbed field can be linked to its original location in the return.
  • Encryption: All documents and extracted data are encrypted in transit and at rest.
  • Access permissions: Only authorized staff can view or modify scrubbed financial records.
  • Exception routing: Any anomalies or incomplete scrubs are routed to human reviewers with detailed context.

This governance framework gives funders full transparency and confidence in every scrubbed document.

Implementation Best Practices

To get the most value from scrubbing automation, teams should establish clear policies and consistent workflows.

  • Define review rules: Identify which forms, schedules, and figures are most critical for underwriting.
  • Set accuracy thresholds: Determine what confidence levels trigger manual review.
  • Integrate scrubbing outputs: Map clean fields directly into CRM and decision models.
  • Train staff on exception handling: Ensure reviewers know how to resolve flagged cases efficiently.
  • Track metrics: Monitor exception rate, turnaround time, and accuracy improvements post-implementation.
  • Update logic regularly: Refresh validation rules as new tax form versions or business rules emerge.

These practices maintain automation reliability while aligning scrubbing outputs with underwriting needs.

Benefits of Using Heron for Scrubbing Tax Returns

  • Speed: Tax returns are reviewed and verified instantly instead of being manually checked line by line.
  • Accuracy: Automated cross-checks catch calculation or reporting errors early.
  • Scalability: Heron processes hundreds of tax packets daily without staff increases.
