Tools for finance teams

Working tools, kept current with the law.

Five utilities we use in practice, made public. Rates and due dates reflect the Income-tax Act, 2025 and the rationalised GST structure as they stand for FY 2026-27.

Rates verified as at 5 August 2026 · FY 2026-27 · Income-tax Act, 2025 · GST slabs of 22 Sep 2025 as amended
Tool 01

Compliance calendar

Every recurring statutory due date — GST, TDS and TCS, payroll, advance tax and MCA — laid out month by month for the financial year you pick. Download any view straight into Outlook or Google Calendar.

Assumptions. Monthly GST filer (GSTR-1 by the 11th, GSTR-3B by the 20th); QRMP dates shown separately where they differ (Karnataka is a 22nd-of-the-month state for quarterly 3B). AOC-4 and MGT-7 assume an AGM held on 30 September. Karnataka professional tax shown (payment and Form 9-A by the 20th). Where a date falls on a holiday the statutory date is shown — extensions notified by CBDT/CBIC during the year are not reflected automatically.
Tool 02

TDS rate finder & calculator

The Income-tax Act, 2025 replaced the familiar 194-series with consolidated tables under Section 393 from 1 April 2026. Pick the nature of payment — the tool gives the new-Act citation, the old-section cross-reference, the threshold test and the deduction.

Payment details
Used for annual-aggregate thresholds

Scope. Resident payees under Section 393(1)/(3) and salary under Section 392, for FY 2026-27. Payments to non-residents (old s.195 family, now Section 393(2)) depend on DTAA relief and are excluded — those need a worked opinion, not a widget. Thresholds reflect the rationalisation effective 1 April 2025 carried into the new Act; the Finance Act 2026 added manpower supply to contract "work" but changed no rates.
Tool 03

GST calculator with product search

Search by product, service or HSN/SAC — the current rate under the rationalised 0 / 5 / 18 / 40 structure fills itself in. Works both ways: add GST to a base price, or extract GST from an inclusive price.

Supply details
No item selected — or set the rate manually below.

Rates. Structure effective 22 September 2025 (56th GST Council), including the February 2026 tobacco transition to the 40% retail-sale-price regime. The item list covers common supplies at 4-digit HSN/SAC level — chapter-level classification, not a ruling. Rate-critical decisions (works contracts, restaurant-in-hotel, mixed supplies, apparel and footwear near the ₹2,500 line) should be confirmed against the notification text.
Tool 04

Salary / CTC structurer

Enter an annual CTC and the structuring choices — the tool builds the component grid, applies EPF on actual basic, Karnataka professional tax and gratuity accrual, and reconciles every rupee back to the CTC.

Structure inputs
12% of actual basic is the position after the wage-ceiling correction
Component grid — ties out to CTC
Conventions. Employer EPF and gratuity accrual sit inside CTC; special allowance is the balancing figure, so the grid always reconciles to the CTC entered. Employee EPF at 12% of actual basic and Karnataka PT (₹200 a month, ₹300 in February) are deductions from gross, not CTC components. Take-home shown is before TDS on salary — run tool 5 for the tax line. ESI (applicable below ₹21,000 monthly gross) is not modelled.
Tool 05

Salary TDS — old vs new regime

The declaration your employer asks for each April, answered with arithmetic. Enter the salary and the deductions you actually use — the tool computes both regimes for FY 2026-27 under the Income-tax Act, 2025 and shows the monthly TDS difference.

Income & deductions
Bengaluru counts as non-metro for HRA
Capped at ₹1,50,000 · now s.123, IT Act 2025
Enter eligible amount · now s.126
Capped at ₹2,00,000 · old regime only
Allowed in both regimes · 14% of basic+DA cap applied
Comparison — FY 2026-27
Method. New regime: standard deduction ₹75,000, slabs 4L–24L, rebate under s.156 of ₹60,000 up to ₹12 lakh total income with marginal relief. Old regime: standard deduction ₹50,000, HRA exemption as the least of the three statutory measures, Chapter VIII deductions as entered, rebate ₹12,500 up to ₹5 lakh. Surcharge from ₹50 lakh (new-regime cap 25%) and 4% cess applied in both. Salary TDS is the annual tax spread monthly under s.392 (old s.192). Illustrative — not a substitute for a computation on your actual Form 16 facts.
