A simple directory of the official Government of India portals for tax, retirement, small savings, GST, property and identity — each paired with the free CoinCalc calculator so you can plan your numbers before you file or invest.
File your return, check Form 26AS / AIS, pay advance tax and verify TDS — all on the official Income Tax Department portal. Use the calculators first to know your liability and which regime to pick.
Manage your EPF passbook and claims with EPFO, and open or contribute to NPS through the official CRA. Project your corpus before you commit.
PPF, the Senior Citizen Savings Scheme (SCSS), Sukanya Samriddhi and NSC are operated through India Post and most banks. Rates are notified quarterly by the Government.
Register, file returns and verify GSTINs on the official GST portal. Split base price and tax with the calculator before invoicing.
Stamp duty and registration charges are set by each State, paid through the State Registration / IGR department portal. Estimate the total cost first.
Your PAN and Aadhaar underpin every financial service. Update or link them only on these official sites — never share OTPs or details elsewhere.
CoinCalc is an independent tool and is not affiliated with, endorsed by, or a part of any government department. The links above point to official Government of India portals; we list them only for your convenience.
