Demat and trading account: what each one actually does
Two accounts, two jobs, usually opened together in one application. Understanding which does what explains why your shares are safe even if your broker is not.
Last checked August 2026. Sources listed at the end.
The short version
- A trading account places your buy and sell orders.
- A holds the shares you bought, electronically, in your name.
- Your shares sit with a depository, NSDL or CDSL, not with your broker.
- You need PAN, Aadhaar linked to your mobile, and a bank account in your own name.
- From 1 September 2026, new single-holder accounts must nominate or formally opt out.
Why there are two
The split exists because buying and holding are genuinely different functions, handled by different institutions under different rules.
| Trading account | Demat account | |
|---|---|---|
| Its job | Places orders on the exchange | Holds what you bought |
| Held with | Your | A depository, through your broker |
| Think of it as | The shop counter | The locker |
| Needed for | Any buying or selling | Shares, ETFs, bonds you hold |
A simple sequence makes it concrete. You tap buy in the app, which is your trading account. The order goes to the exchange and is matched. The next working day, under T+1 settlement, the shares appear in your demat account. When you sell, the reverse happens.
Demat is short for dematerialised. Shares were once physical certificates that could be lost, forged or damaged. They now exist as electronic records, which is why transfers take a day rather than weeks.
Who actually holds your shares
This is the part worth understanding properly, because it answers the question everyone eventually asks.
India has two depositories: NSDL and CDSL. They maintain the ownership records for every dematerialised share in the country. Your broker is a depository participant, meaning an agent that opens and services your account with one of them.
The important consequence: your shares are recorded in your own name at the depository, not held by your broker. If your broker ceased operating tomorrow, your holdings would still be yours and could be moved to another broker. That is a structural protection, not a promise from any company.
You can verify this yourself. Both depositories offer a statement showing your holdings directly, independent of anything your broker displays. Checking it once a year against your broker app is a sensible habit.
Opening one
Almost entirely online, usually free, and typically active within a day or two.
What you need:
- PAN card. Mandatory, no exceptions.
- Aadhaar linked to the mobile number you have with you, because verification uses an OTP.
- A bank account in your own name, plus a cancelled cheque or a recent statement.
- A photograph and a signature image.
- Income proof, only if you want to trade derivatives. Not needed for ordinary investing.
The check is done once and is generally recognised across the system, so opening a second account later is faster.
Nomination, which changes on 1 September 2026
Under revised SEBI rules effective 1 September 2026, new single-holder demat accounts and mutual fund folios must either name a nominee or file a formal opt-out declaration. The field cannot be left blank.
You can name up to three nominees with percentage shares, and only the nominee name and relationship are mandatory now. Do it while opening the account. See nomination and succession.
What it costs to keep
Opening is usually free. Holding is not always.
- Annual maintenance charge. A yearly fee for the demat account, ranging from zero at some brokers to several hundred rupees.
- Depository participant charges. A flat amount charged per company, per day, when you sell from your demat holdings. This is why selling small quantities of many different shares is disproportionately expensive.
- Trading charges. Brokerage and statutory levies, covered in charges and costs.
A basic services demat account exists with lower or nil maintenance charges for small holdings, intended for people holding modest amounts. It is worth asking about if your portfolio is small.
Practical things worth knowing
- You do not need a demat account for ordinary mutual funds. Including index funds. Only shares, ETFs, bonds and similar require one.
- One PAN, multiple accounts. You can hold demat accounts with several brokers, though it complicates tracking and each may carry its own maintenance charge.
- Dormant accounts still cost. An unused account can accumulate maintenance charges. Close it properly rather than abandoning it.
- Check your consolidated account statement. Both depositories send a periodic statement covering all your holdings. Read it. It is also how many people discover forgotten holdings.
- Tell your family the account exists. A perfectly maintained account is useless if nobody knows to look for it.
That last point sounds trivial and is not. A large amount of unclaimed investment in India exists simply because nobody knew where to look.
What to remember
- A trading account places orders. A demat account holds what you bought.
- Your shares are recorded in your own name at NSDL or CDSL, not held by your broker.
- If a broker fails, your holdings remain yours and can be moved elsewhere.
- You need PAN, Aadhaar linked to your mobile, and a bank account in your own name.
- From 1 September 2026, new single-holder accounts must nominate or formally opt out.
- DP charges apply per company per day when selling, so selling many small holdings is costly.
