Tax

Tax calculators for India cut through the complexity of GST slabs, TDS rates, and income tax provisions — giving businesses, freelancers, and salaried individuals exact figures without the risk of manual calculation errors. Whether you need to raise a GST-compliant invoice, understand how much TDS will be deducted from your FD interest, or verify a vendor's deduction, these tools give you the answer in seconds.

GST in India: four slabs, one calculator

India's GST system applies across four rate slabs — 5%, 12%, 18%, and 28% — with a zero-rate category for essentials. For intra-state transactions, the GST amount is split equally between CGST (Central GST) and SGST (State GST). For inter-state transactions, IGST applies at the full rate. The GST Calculator handles both directions: add GST to a base price, or strip GST from an inclusive price to recover the net amount.

Common real-world uses: calculating the GST on a service invoice before sending it to a client, verifying the GST amount on a purchase bill, or determining the base price from a GST-inclusive quote.

TDS: deduct right, deposit on time

TDS (Tax Deducted at Source) is one of the most misunderstood compliance requirements in India. The payer — not the recipient — bears the legal responsibility for correct deduction and timely deposit. The TDS Calculator covers nine common payment types under the Income Tax Act: FD interest, rent (building and machinery separately), professional fees, technical services, contractor payments, commission, and property purchase. It also accounts for the PAN penalty — deduction doubles (or hits 20%) when the payee has not furnished a PAN.

Key compliance deadlines

TDS deducted in any month must be deposited by the 7th of the following month (except March, where the deadline is 30 April). Quarterly TDS returns are due in July, October, January, and May. Late deduction attracts interest at 1% per month; late deposit attracts interest at 1.5% per month. Errors in TDS are common and costly — using a calculator before processing payments eliminates arithmetic mistakes that trigger notices.

Planning your taxes, not just calculating them

Beyond compliance, tax calculators are planning tools. Knowing the GST rate on a service before quoting helps you price correctly. Understanding TDS thresholds on FD interest helps you structure deposits across family members to minimise deductions. And verifying the TDS applicable on a property purchase protects you from non-compliance penalties on a high-value transaction. Use these tools as a first step before consulting a chartered accountant for complex situations.
