Understanding Share Capital in Companies

Every company that raises money by selling shares operates within a very specific numerical ladder. Before it sells a single share, the law makes it declare a ceiling on how much it can ever raise. After that, every rupee it actually collects moves through a series of clearly defined stages. This ladder is called share capital, and understanding its layers is one of the first building blocks of corporate accounting. Once you see how these categories connect, financial statements, company registration documents, and even news about companies “raising capital” start making a lot more sense.

What is share capital 🔗

Share capital is the money a company raises by issuing shares to investors in exchange for ownership. It is the primary source of long-term, owned funds for a company, as opposed to borrowed funds like loans or debentures. When you buy a share, you are not lending the company money that it must repay with interest; you are buying a small piece of ownership, and your return depends on the company’s performance.

What makes share capital tricky for most students is that it is not a single number. A company’s balance sheet does not show “share capital” as one flat figure. Instead, it breaks the concept into several nested categories, each narrower than the one before it. Think of it as a set of concentric circles: the outermost circle is the absolute legal maximum, and each inner circle represents a smaller, more concrete amount that has actually moved from investors to the company.

The layered structure of share capital 🔗

The Companies Act, 2013 recognises share capital in several distinct senses, and each one represents a progressively smaller subset of the category before it, moving from what a company is legally allowed to raise down to what it has actually collected in cash.

Authorised capital 🔗

Authorised capital, also called nominal or registered capital, is the maximum amount of share capital a company is permitted to raise, as fixed in its Memorandum of Association. Under Section 2(8) of the Companies Act, 2013, it is defined as the capital authorised by the memorandum to be the maximum amount of share capital a company can have. A company cannot issue shares beyond this limit under any circumstances. If it needs to raise more funds through equity later, it must first go through a formal legal process to increase this ceiling.

For instance, if a company sets its authorised capital at ₹10,00,000 divided into shares of ₹10 each, it can never issue more than 1,00,000 shares unless it amends its memorandum and increases this limit through a shareholder resolution and a filing with the Registrar of Companies.

Issued capital 🔗

Issued capital is the portion of authorised capital that a company actually offers to investors at a given point in time. A company rarely issues its entire authorised capital in one go; it usually issues shares in tranches as its funding needs grow. The part of authorised capital that has not yet been offered is called unissued capital, and it remains available for future issues. Issued capital is always a part of authorised capital and can never exceed it.

Subscribed capital 🔗

Subscribed capital is the part of issued capital that investors actually agree to take up and pay for. When a company offers shares to the public, demand can vary. A well-regarded company might receive applications for more shares than it offered, a situation called oversubscription. A less popular offer might attract fewer applications than the shares available, called undersubscription. Whatever portion of the issued shares investors formally apply for and are allotted becomes the subscribed capital, and it is always equal to or less than issued capital.

Called-up capital 🔗

Companies rarely ask shareholders to pay the full face value of a share immediately. Instead, they often collect the amount in instalments, known as calls: for example, on application, on allotment, and on one or more subsequent calls. Called-up capital is the part of the subscribed capital that the company has formally demanded from shareholders so far. According to Section 2(15) of the Companies Act, 2013, called-up capital means the part of the capital that has been called for payment. If a company calls ₹5 on each of 10,000 shares with a face value of ₹10, its called-up capital on those shares is ₹50,000, even though the face value is higher.

Paid-up capital 🔗

Paid-up capital is the amount shareholders have actually paid against the calls made on them. In an ideal scenario, called-up capital and paid-up capital are identical, but in practice, some shareholders delay or default on payment. The unpaid portion is recorded separately as calls-in-arrears. So paid-up capital is calculated as called-up capital minus calls-in-arrears. This is the figure that represents real cash the company has received and can actually deploy for its operations, which is why paid-up capital is often considered the most important number of the lot for practical purposes.

It is worth noting that private companies in India no longer face a statutory minimum paid-up capital requirement. This requirement, once fixed at ₹1,00,000 for private companies, was removed by the Companies (Amendment) Act, 2015, giving founders more flexibility when structuring a new company.

Uncalled capital 🔗

Uncalled capital is the portion of subscribed capital that the company has not yet asked shareholders to pay. Shareholders remain liable to pay this amount whenever the company decides to make a future call. It essentially represents a reserve of committed but not-yet-collected funds sitting with the shareholders rather than the company.

Reserve capital 🔗

Reserve capital is a special category carved out of uncalled capital. A company may pass a special resolution declaring that a specific portion of its uncalled capital will not be called up during the company’s normal life, and will only be demanded from shareholders if the company goes into liquidation. This acts as a safety cushion for creditors, ensuring there is an additional pool of money shareholders are legally bound to contribute if the company winds up and its regular assets are not enough to pay off liabilities.

Seeing the hierarchy together 🔗

Because each category sits inside the one before it, it helps to see the relationship laid out clearly:

Reading this table top to bottom is essentially reading the life cycle of a company’s equity funding, from a legal permission on paper to actual cash sitting in the company’s bank account.

Share capital and the Memorandum of Association 🔗

None of this hierarchy exists informally. Every company with a share capital must state its authorised capital clearly in the capital clause of its Memorandum of Association, one of the six mandatory clauses required under Section 4 of the Companies Act, 2013. This clause specifies the total amount of capital the company can raise and how it is divided into shares of a fixed face value.

Because this clause sets a hard legal ceiling, a company cannot simply decide one day to issue more shares than its memorandum allows. It must first pass an ordinary resolution in a general meeting to alter the capital clause, and then file the change with the Registrar of Companies. This is exactly why start-ups often set their authorised capital slightly higher than their immediate funding needs. It gives them room to issue more shares later, for example to bring in new investors or create an employee stock option pool, without going through the amendment process again in the near term.

Why this distinction actually matters 🔗

These categories are not just examination terminology. They show up constantly in real financial decisions. When a bank or investor evaluates a company, paid-up capital tells them how much money has genuinely entered the business, while authorised capital only tells them the theoretical ceiling. A company with a large authorised capital but a small paid-up capital has simply left itself room to grow, not necessarily raised a large sum already.

Similarly, paid-up share capital is presented in financial statements after deducting calls-in-arrears from the subscribed capital, which is why the paid-up capital figure on a balance sheet is the most accurate snapshot of a company’s actual equity funding at any point. Understanding this hierarchy also helps you read company registration documents, prospectuses, and even news reports about companies raising fresh capital with far more clarity.

What do you think? If you were advising a new company on setting its authorised capital, would you recommend keeping it close to the immediate funding need, or setting it noticeably higher to leave room for future fundraising? And why might a company choose to keep a portion of its capital as reserve capital instead of simply calling it up earlier?
