When you buy a share on the Pakistan Stock Exchange, it doesn’t land in your name at the company’s own register. It lands as an electronic book entry inside the Central Depository Company (CDC), Pakistan’s sole securities depository, and exactly how that entry is held decides who can move it and what happens to it if something goes wrong.
Most retail investors end up in one of two structures. A sub-account sits inside your broker’s own CDC participant ledger, and the broker operates it on your behalf: convenient for everyday trading, but the broker, not you, sends the instructions that move your shares. An Investor Account, opened directly with CDC through its Investor Account Services (IAS), is operated only on your own written instruction and travels with you if you change brokers, though you still need a broker to place trades. A third structure, the omnibus account, pools many people’s holdings under one legal account run by an intermediary, usually a fund trustee or custodian, so no individual investor’s name shows up against the shares at the depository level. Pakistan’s mutual funds work this way. Here’s how each one actually functions, and where the risk sits in each.
Sub-account vs Investor Account: who’s actually pulling the lever
CDC’s own FAQ draws the line simply: sub-accounts are maintained and operated by CDC Participants (stock brokers and financial institutions) on behalf of the holder, while Investor Accounts sit under the complete control of CDC and the account holder, moved only on the holder’s direct written instruction. In practice, when you sign up with almost any brokerage in Pakistan and get a trading app, you’re opening a sub-account. Your broker’s participant code sits in front of your holdings, and the broker is the one instructing CDC to move shares in and out for settlement.
An Investor Account flips that. You apply directly to CDC, get your own IAS number, and from that point only your signed instruction moves securities in or out of it. That independence comes with a catch worth knowing before you open one: an Investor Account by itself doesn’t let you trade on the PSX. You still need to appoint a broker, a TREC holder, to place buy and sell orders, and shares bought through that broker settle into your Investor Account rather than a sub-account. CDC introduced the Investor Account specifically to give people that direct line, after years of sub-accounts being the only option and control sitting entirely with the broker.
The practical difference shows up most when you switch brokers. A sub-account lives inside your old broker’s own participant ledger, so moving firms usually means submitting a transfer request to shift your holdings into a sub-account (or Investor Account) at the new one. An Investor Account doesn’t move at all when you change brokers, because it was never tied to a specific broker in the first place. You just start routing new trades through a different TREC holder while your existing IAS number and holdings stay put.
Sub-account holdings are recorded separately from your broker’s own house account on CDC’s books, which is meant to keep your shares identifiable as yours even if the brokerage runs into financial trouble. That’s a real structural safeguard, but it’s also the reason CDC built the Investor Account as an alternative for people who want the custody layer entirely out of their broker’s hands: fewer moving parts between you and a broker failure, at the cost of an extra account to manage and slightly less convenience for frequent trading.
Where an actual omnibus account shows up on the PSX
Strictly speaking, an omnibus account is one where a broker or custodian pools several clients’ assets into a single account at the depository or clearing level, so the depository sees one name, the intermediary’s, rather than each underlying investor. A CDC sub-account doesn’t quite fit that description: each one carries its own account number inside the CDS, visible and distinct even though your broker operates it. What you have with a sub-account is closer to a disclosed custody arrangement than a blind pool.
The cleaner example of pooled, omnibus-style holding on the PSX is a mutual fund. When you buy units in an equity fund, you don’t get a CDC sub-account with individual company shares sitting in it. The fund itself, through its trustee, holds one consolidated CDC account containing the underlying stocks, and you own units representing a slice of that pooled portfolio. Your name never appears against Engro or Lucky Cement shares at the depository; only the fund’s account does. That’s the omnibus principle in its clearest local form: convenience and diversification for you, in exchange for the fund trustee sitting between you and the actual securities.
It’s worth clearing up one common assumption here: Roshan Digital Account holdings for overseas Pakistanis aren’t pooled this way. Each RDA investor gets their own individually numbered CDC account, tied to their CNIC or NICOP, not a blind slice of a custodian’s combined position. The fund trustee model remains the clearest example of genuine omnibus holding on the PSX; the common thread across pooled setups elsewhere is the same trade-off, reduced paperwork and cost in exchange for handing day-to-day control, and sometimes visibility, to whoever operates the pooled account.
Comparing the three structures
| Structure | Who operates it | Who’s named at CDC | Can trade on PSX directly | If the intermediary fails |
|---|---|---|---|---|
| Sub-account | Your broker (CDC Participant) | You, under the broker’s participant code | Yes, that’s its purpose | Holdings are recorded separately from the broker’s house account, but you’re relying on that segregation holding up |
| Investor Account (IAS) | You, by written instruction | You, directly | No, a broker is still required to place trades | Custody sits with CDC itself, independent of any single broker’s solvency |
| Omnibus / pooled account (e.g. mutual fund) | The fund trustee or custodian | The trustee or custodian, not you | No, you buy units, not the underlying shares | You hold a claim on the fund, governed by trust and SECP fund regulations, not a direct security |
Individual, joint, or company: whose name is actually on the account
Separate from who holds custody is a second question: whose name sits on the account as the legal owner. CDC’s own account opening forms offer individuals a choice between operating the account singly, jointly with named co-holders, or under an “either or survivor” mandate, alongside options for a body corporate to open an account in the company’s name with authorised signatories and a board resolution on file.
The “either or survivor” mandate does the same practical job that JTWROS, joint tenancy with right of survivorship, does in a US brokerage account: either holder can operate the account alone, and the survivor keeps operating it after the other’s death. But it isn’t a precise legal match. JTWROS is a common-law property concept where the surviving owner automatically takes full title to the whole account, bypassing probate entirely. “Either or survivor” mandates, as interpreted in courts across the region for equivalent bank accounts, work more as an operating instruction: they let the institution discharge itself by dealing with the survivor, without necessarily overriding succession law. The deceased holder’s share can still be subject to a claim from other legal heirs under Pakistani inheritance rules, whether that’s Islamic succession law for Muslim account holders or the Succession Act for others, even after the survivor has been operating the account. Anyone opening a joint CDC account expecting it to behave exactly like a US JTWROS account, an automatic full transfer that sidesteps inheritance shares entirely, should confirm the point with a lawyer rather than assume it.
A company account is the more straightforward option of the three. Any private limited company registered with SECP can open its own sub-account or Investor Account, operated by whichever directors or officers the board authorises, backed by the corporate documentation CDC requires for body corporate accounts. That opens up a fourth ownership model worth a closer look: holding your personal portfolio through a company you set up for that purpose, rather than in your own name.
Does routing your portfolio through a company actually save tax in Pakistan?
In the UK, a personal investment company (a private company set up purely to hold shares, funds, and other investments) is a well-worn tax planning tool: profits can sit and compound inside the company at corporate rates, with income tax only triggered when money is actually extracted. It’s tempting to assume the same structure pays off on the PSX. It mostly doesn’t, and the reason comes down to a change in how Pakistan taxes listed securities.
Since the Finance Act 2024, capital gains on listed securities acquired on or after 1 July 2024 are taxed at a flat 15% for anyone on the Active Taxpayer List, whether that’s an individual or a company. Before that change, individuals benefited from a holding-period slab that could fall all the way to 0% after six years, an incentive that rewarded patient, direct personal ownership. That gap has closed. A filer company and a filer individual now pay exactly the same 15% on a share sale.
Dividend income tells a similar story: Section 150 withholding is 15% for filers and 30% for non-filers, and that rate applies whether the shareholder receiving the dividend is a person or a company. The difference shows up one step later. For an individual, that 15% withholding is usually the end of the tax story on that income. For a company, the dividend lands as corporate income, and if the company then wants to pass that cash to you personally, it has to declare a dividend of its own, triggering a second round of Section 150 withholding on the way out.
A worked example makes the drag concrete. Say your personal portfolio and a company you set up both realise a PKR 1,000,000 gain on shares bought after 1 July 2024, and both are active filers. Held personally, you pay 15% CGT, PKR 150,000, and keep PKR 850,000 with nothing further owed to move that money into your own account. Held through the company, the company also pays 15% CGT on the same gain, leaving PKR 850,000 inside the company. To get that cash into your own pocket, the company pays it out as a dividend, and another 15% withholding applies: PKR 127,500 withheld, leaving you with PKR 722,500. Two legitimate 15% rates stack into an effective 27.75% by the time the money actually reaches you, on top of the annual cost of keeping a private limited company compliant with SECP, a statutory audit, and a separate corporate tax return.
That math flips if you never plan to extract the money. Gains and dividends left inside the company to be reinvested only face the second tax layer whenever they’re eventually paid out, so a company wrapper can still make sense as a long-term holding vehicle for capital nobody intends to touch for years. It can also make sense for reasons that have nothing to do with tax: pooling several family members’ capital under one governed entity instead of scattered individual holdings, keeping a defined shareholding structure that transfers by a straightforward share sale rather than triggering succession claims on individual securities, or separating investment assets from an individual’s other personal liabilities. In Pakistan, a personal investment company is closer to an estate-planning and governance tool than a tax shortcut.
Checking which one you actually have
If you’ve been investing through a brokerage app and have never filled out a separate IAS form, you almost certainly hold a sub-account rather than an Investor Account. You can confirm your account type and number, and see your holdings independent of any single broker’s app, through the CDC Access portal at cdcaccess.com.pk, which consolidates your electronic and physical portfolio across whichever participants you deal with. It’s worth checking before you add significant new capital, particularly if you’re deciding between staying with a sub-account for convenience or moving to an Investor Account for the extra layer of direct control.
Frequently asked questions
Is my broker sub-account safe if my broker shuts down?
Sub-account holdings are recorded separately from your broker’s own proprietary account on CDC’s books, which is designed to keep your shares distinguishable from the firm’s assets. That’s a real safeguard, but it isn’t the same as removing your broker from the equation entirely, which is what an Investor Account does. For deeper context on what happens when a company you’ve invested in, as opposed to your broker, runs into serious trouble, see our guide to what happens to your shares if a company goes bankrupt, a related but separate risk.
Can I convert a sub-account into an Investor Account?
Yes. You open the Investor Account directly with CDC, then submit a request to transfer your existing holdings across from your sub-account. The reverse transfer, moving shares from an Investor Account into a sub-account, is also possible if you decide direct custody isn’t for you.
Do I still need a broker if I open a CDC Investor Account?
Yes. An Investor Account gives you direct custody of your shares, not trading access. You still need to appoint a TREC holder to execute buy and sell orders on the PSX; the shares just settle into your own account instead of the broker’s sub-account structure.
Does buying a mutual fund make me a shareholder of the companies it holds?
No. You own units in the fund, and the fund’s trustee owns the underlying shares in one pooled CDC account. You get the economic exposure and, depending on the fund, a share of dividends passed through as fund distributions, but you don’t appear as a shareholder of the individual listed companies and you don’t get direct voting rights in them.
What’s a sensible starting point for a new PSX investor?
For most people opening their first account, a sub-account through a regulated brokerage is the practical starting point, since it’s simpler to set up and comes bundled with trading access. If you’re just getting oriented on how the exchange and brokers fit together before opening anything, our explainer on how a stock exchange works and our step-by-step guide for overseas Pakistanis opening an account are good places to start before deciding whether a direct Investor Account is worth the extra step.
