Core Features
Everything a Tax Professional Needs, Built Into One Platform
Every feature that made ExpressITR India's most used income tax filing software is now part of Spectrum Cloud, with deeper automation, smarter tax computation, and a unified compliance dashboard.
AIS & 26AS Auto-Fetch & Pre-Fill
Fetch AIS and Form 26AS directly from the Income Tax portal. Auto-populate ITR fields, match AIS data against your form data, and ensure accurate tax liability — with only valid deductions applied.
Old vs New Tax Regime Comparison
Real-time side-by-side comparison of tax liability under old and new regimes for each client. Instantly see the most tax-efficient option with automatic recalculation of deductions, surcharge, and cess.
Automated Tax Computation
Real-time tax calculation with section-wise deductions, advance tax liability, and automated 234A/234B/234C interest calculations — accurate every time, no manual formula.
Tax Audit Form Preparation
Prepare and file tax audit forms — 3CA-3CD, 3CB-3CD, 10B, 10BB — with data pre-filled from the ITR to eliminate duplication. Complex audit forms simplified within the same workflow.
Multi-Tabbing, Simultaneous Multi-Client Filing
Work on ITRs of multiple clients at the same time using the multi-tabbing facility. Switch between clients without losing progress on any of them — built for peak season speed.
Bulk PAN Import & Master Management

Financial Report Preparation

Real-Time Notice & Order Tracking
Live filing status with real-time updates on notices and orders across all clients. Download acknowledgments and compliance summaries in Excel or PDF for client reporting — all within the centralised dashboard.
Tax Regime Comparison
Old vs New Tax Regime, Instant Comparison for Every Client
The most important tax decision your clients make each year is the regime choice. Spectrum Cloud's real-time regime calculator eliminates the guesswork, showing exact tax liability under both regimes side-by-side, with one click to select and file under the optimal regime.
- Eligible for 80C, 80D, 80G, HRA, LTA deductions
- Higher tax slabs with deduction benefits
- Better for clients with significant investments and expenses
- Requires proof verification, auto-validated in Spectrum Cloud
- Lower tax slabs, standard deduction of ₹75,000 (FY 2024-25)
- No 80C/80D deductions, simpler computation
- Better for clients with limited deductions or lower income
- Form 10-IEA e-filing for opting out, supported in Spectrum Cloud
Spectrum Cloud computes both regimes simultaneously and highlights the lower-tax option for every client, so you make the right recommendation every time, in seconds.
