Income Tax Computation & Filing Workflow Structuring

Structured Income Tax Preparation

Income tax return preparation involves multiple data sources — Form 26AS, AIS, bank statements, capital gains statements, and client-provided documents. Manual consolidation is time-consuming and error-prone.

Prefiler automates the structuring layer. Upload source documents. The platform maps income across heads, validates deduction eligibility, reconciles TDS credits, and generates a computation-ready output.

How It Works

Source documents are parsed and classified. The deterministic engine maps transactions to income heads (salary, house property, business, capital gains, other sources) and identifies applicable deductions under Chapter VI-A.

TDS credits from Form 26AS are matched against computed tax liability. Advance tax payments are reconciled. The output provides a structured computation sheet with identified gaps and validation flags.

Key Capabilities

  • • Multi-source income consolidation and head mapping
  • • Chapter VI-A deduction eligibility validation
  • • Form 26AS and AIS reconciliation
  • • Capital gains structuring by asset class and holding period
  • • Advance tax and self-assessment tax reconciliation
  • • Pre-filing gap identification and readiness scoring

Built for Professional Practice

Prefiler does not compute final tax liability. It structures data, validates inputs, and surfaces inconsistencies. The professional reviews the output, applies judgment, and makes filing decisions.

This separation ensures compliance with professional standards while reducing the manual effort required for routine computation and validation tasks.

Frequently Asked Questions

Does Prefiler file income tax returns?

No. Prefiler structures data and validates computations. Filing occurs through the official income tax portal or your existing filing software.

Which return types are supported?

Prefiler supports structuring for ITR-1 through ITR-6 with income head mapping and deduction validation.

Can it handle capital gains computations?

Prefiler structures capital gains data by asset type and holding period. Final computation verification remains with the practitioner.

How does Prefiler handle TDS credits?

TDS data from Form 26AS and AIS is cross-referenced against reported income to identify unmatched credits and excess deductions.
