Called up share capital is the portion of a company’s issued shares that the board of directors has formally demanded shareholders pay. Under the UK Companies Act 2006, Section 547, it equals the total of calls made on shares, plus any amounts paid up without being called, plus any amounts due on a specified future date under the terms of allotment.1Legislation.gov.uk. Companies Act 2006, Section 547 – Called-Up Share Capital It is the figure that matters when a company has issued shares on a partially paid basis, collecting some money upfront and reserving the right to demand the rest later.
How It Fits With Issued, Uncalled, and Paid-Up Capital
Share capital sits in layers, and called up capital is one of them. Confusing the layers is the main reason the term causes trouble, so it helps to see them side by side.
- Issued capital is the total nominal value of shares actually allotted to shareholders. A company may be able to issue millions of shares but have only placed a fraction.
- Called up capital is the portion of that issued capital the company has formally demanded payment for. If shares were issued at £10 each but only £6 per share has been called, called up capital is £6 per share.
- Uncalled capital is the remainder the company has not yet asked for. In the example above, £4 per share stays uncalled, acting as a reserve the board can tap later.
- Paid-up capital is the cash actually received for the amounts called. If some shareholders have not paid what they owe, paid-up capital will be lower than called up capital.
The gap between called up and paid-up is “calls in arrears”: money shareholders legally owe but have not handed over. A company that calls up £500,000 and receives only £450,000 has £50,000 in arrears. That £50,000 is a receivable on the company’s books and a debt the shareholder must settle.2Investopedia.

Why Companies Call Capital in Stages
Demanding full payment on day one is the simplest route, and most companies take it. Partially paid shares still serve a real purpose. A company raising a large sum may not need all the cash immediately, and collecting it in stages avoids sitting on idle money while locking in investors’ commitments. This is common in mining, infrastructure, and other capital-intensive industries where spending unfolds over years.
Partially paid shares also lower the entry barrier for investors. Someone who cannot commit £100,000 upfront might comfortably commit £25,000 now with the understanding that more will follow. The company, meanwhile, has contractual access to the remaining £75,000 whenever the board decides to call it. The arrangement works like a credit facility backed by shareholders rather than banks.
The uncalled portion also shows up to creditors as a financial cushion. Shareholders carry outstanding obligations the company can convert into cash without the time and cost of a new share offering, because the shares are already issued and the obligation already exists.
How a Call Actually Works
Making a call is a formal legal process, not a casual request. The company’s articles of association and the original terms of allotment govern how it must be done.
The process starts with a board resolution. Directors specify how much per share is being called and set the payment deadline. The amount does not have to cover the entire unpaid balance; the board can call any portion, and it can make multiple calls over time as funding needs arise.
Once the resolution passes, the company issues a formal call notice to every shareholder holding partially paid shares. The notice turns what was a conditional future obligation into an enforceable debt. Model articles typically require at least 14 days’ notice before payment is due. The notice must state the amount due, the payment deadline, and where and how to pay.
One rule governs fairness: calls must be uniform across all shares of the same class. If the board calls £3 per share, every shareholder in that class owes £3 per share. The board cannot single out individuals for selective calls. Breaking the uniformity principle can invalidate the entire call and open the company to challenges from affected shareholders.
How Called Up Capital Appears on the Balance Sheet
Called up share capital shapes the equity section of the financial statements. The standard presentation starts with the total called up share capital, then deducts any calls in arrears to arrive at paid-up capital. Readers get an honest picture: the company has a legal right to the full called up amount, but only the paid-up portion represents cash in hand.
Calls in arrears appear either as a direct deduction from called up capital on the face of the balance sheet or as a disclosure in the notes. Companies cannot bury the figure. If £50,000 of called capital is unpaid, that fact must be visible, because it is both a risk (shareholders might default) and an asset (the company holds a legally enforceable receivable).
What Happens When a Shareholder Doesn’t Pay
A shareholder who misses a call payment is in default, and the consequences escalate in stages. Articles of association usually spell out the exact process.
Interest on Overdue Amounts
The company can charge interest on the unpaid amount from the date it was due until the date it is actually paid. The rate depends on what the articles or the original terms of allotment specify. If neither sets a rate, a default statutory rate applies. Under the Indian Companies Act 2013 (Table F), this default caps at 10% per annum. UK model articles historically set this at 5% per annum. The board typically has discretion to waive interest in part or in full.
Lien on Shares
The company holds a lien on the defaulting shareholder’s partially paid shares. The lien gives the company a legal right to retain those shares as security for the unpaid debt. While it is in effect, the shareholder generally cannot transfer or sell the shares. The lien remains until the shareholder clears the outstanding balance plus any accrued interest.
Forfeiture
Forfeiture is the most severe remedy. If a shareholder still has not paid after repeated demands, the board can pass a resolution to cancel the shares entirely. The typical process requires a final warning notice, often with a minimum 14-day deadline, making clear that the shares will be forfeited if payment is not received. The Companies Act 2006 recognizes forfeiture of shares for failure to pay any sum payable on them as a valid reduction in a company’s share capital.3Legislation.gov.uk. Companies Act 2006, Part 18 – Acquisition by Limited Company of Its Own Shares
Once shares are forfeited, the shareholder’s name comes off the register of members. Any money previously paid toward those shares is lost; the company keeps it and typically transfers it to a forfeited shares account. The forfeited shares can then be reissued to new investors, often at a discount to their original price, though they cannot be reissued at less than the amount remaining unpaid on them. A former shareholder may still be liable for outstanding calls and interest, though this residual liability usually covers only the gap between what was owed and what the company recovers on reissue.
Not the Same as a Private Equity Capital Call
Called up share capital is sometimes confused with the “capital calls” common in private equity and venture capital funds. The mechanics look similar, since both involve demanding money that investors previously committed, but the legal structures differ.
Called up share capital operates within corporate law. Shareholders own partially paid shares in a company, and the board makes calls under the articles of association. The shareholder’s obligation attaches to specific shares, and the consequences of non-payment are governed by corporate statutes.
Capital calls in private equity operate under partnership or fund agreements. Limited partners commit a total amount to a fund, and the general partner draws down that commitment over time as investment opportunities arise. Consequences of failing to meet a capital call depend on the limited partnership agreement rather than corporate law, and they often include dilution of the defaulting partner’s interest, forced sale of their stake, or loss of their existing investment. The underlying relationship is a partnership interest, not share ownership.
Where the Concept Applies
Called up share capital shows up most often in the UK and Commonwealth countries, where corporate law has long accommodated partially paid shares. The UK Companies Act 2006 provides the statutory framework, including the definition in Section 547.
In the United States, partially paid shares are uncommon. The Model Business Corporations Act, which forms the basis of corporate law in most states, generally treats shares as fully paid and nonassessable once issued, meaning the company cannot come back later and demand more money. Some older state statutes and specific industries still permit assessable stock, but for most U.S. corporations the concept simply does not apply. Indian, Australian, and South African corporate law all accommodate partially paid shares and use terminology similar to the UK framework.
If you come across called up share capital in a set of financial statements, check where the company is incorporated. The specific rules on calls, interest, and forfeiture will depend on that jurisdiction’s corporate statute and the company’s own articles of association.
