# Tax & Compliance Validation

> Verify tax calculations, flag missing deductions, and surface compliance risks before filing across corporate income tax, payroll, and VAT returns.

### Overview

Tax & Compliance Validation is a workflow to verify tax calculations, flag missing deductions, and surface compliance risks **before filing** across **corporate income tax, payroll, and VAT** returns.

It supports pre-filing validation — entity and period capture, recomputation/verification of tax math, deduction completeness checks, and compliance risk flagging — in one streamlined workflow.

**What you get:** a structured table of extracted and calculated fields you can review, edit, and export.

<Tip>
  To set up the workflow (creating sessions, uploading documents, running a workflow, and exporting), see [Setting Up a Workflow](/workflows/setting-up-a-workflow) for a comprehensive guide.

  This page focuses on what's specific to **Tax & Compliance Validation**.

### What's specific to Tax & Compliance Validation

1. **Verification compares logic, not just totals.**
   Confirm that the tax was computed using the correct basis, rates, and rules for the filing type and period.
2. **Missing deductions must be explicit and actionable.**
   List missing deductions clearly (what is missing and why it appears eligible) to speed remediation.
3. **Compliance risk should reflect filing impact.**
   Use the Compliance Risk field to summarise risk severity and the likely impact (penalties, exposure, audit flags).

### Customising Tax & Compliance Validation columns

You can tailor columns to match your internal review checklist.

* Add columns for rate used, penalty/interest estimate, supporting schedule presence (Yes/No), reconciliation status (e.g., TB vs return), and reviewer sign-off.
* Rename columns to be explicit (for example, "Taxable base (₦)" or "Calculated tax (₦)").
* Keep column names clear and unambiguous to improve extraction and validation consistency.

### Important Notes

* Always confirm the filing type, period, and entity identifier match the filing package.
* If a field is consistently wrong, simplify the column name or add a short instruction to the column prompt.
* Treat this workflow as a pre-filing control; final filing decisions should follow your approval process.
