The short answer
A capital call is a demand by a fund's general partner or manager that investors contribute money they have committed, or additional money, to the entity. Syndications and private funds use them to pay for purchases, development or shortfalls, and their agreements set penalties for investors who do not pay. A DST cannot make one: in Rev. Rul. 2004-86 the trustee may not accept additional contributions of assets, including money, so a trust's reserves have to be raised at the start.

Fund filings show how calls work and what happens when an investor misses one.
A qualified opportunity fund partnership's Form 10-K for 2025 explains that a limited partner who defaults on any part of its capital commitment faces the remedies in the partnership agreement, including forfeiture of its voting rights and a substantial portion of its interest or cancellation of its undrawn commitment. Non-defaulting partners may have to contribute more, up to their own undrawn commitments, to cover the shortfall.
The same filing warns that a lender to the fund may be secured by the partners' obligations to contribute capital and could call capital from them if the fund cannot repay. A capital commitment is therefore a contingent liability, not just an investment amount.
It also flags an opportunity zone timing problem. Gain must be invested in a qualified opportunity fund within the 180-day period that begins on the date of sale under section 1400Z-2(a)(1), and the fund warns that it might not call capital within 180 days of an investor's subscription, or might call it when the investor has no eligible gain left to invest. See qualified opportunity zones.
In a worked example, a commitment is drawn in stages.
Hypothetical: you commit $1,000,000 to a development partnership. It calls $400,000 at closing and $300,000 in year two, leaving $300,000 undrawn. Each contribution adds to your basis in the partnership interest under section 722. If you cannot meet the year-two call, the agreement's default remedies apply. Run your own numbers with your CPA.
It bites when a property needs money the owners did not plan to provide.
Rev. Rul. 2004-86 bars the trustee from accepting additional contributions of assets, including money, and lets it keep only a reasonable reserve. That protects you from calls but means a trust whose costs outrun reserves cannot raise new equity; see DST repairs, reserves and no new capital and the DST springing LLC.
Tenant-in-common co-ownership sits in between. Rev. Proc. 2002-22 requires each co-owner to share all revenues and costs in proportion to its interest, and bars the other co-owners, the sponsor or the manager from advancing a co-owner's share unless the advance is recourse and lasts no more than 31 days. In practice each co-owner must fund its own share when costs arrive.
A syndication that can call capital also cannot take your exchange proceeds: a partnership interest is not real property for section 1031 under Reg. section 1.1031(a)-3(a)(5)(i). See 1031 into a syndication or LLC interest.
Related questions
Can a DST ever ask me for more money?
Under the structure in Rev. Rul. 2004-86 the trustee cannot accept additional contributions, including money. If a trust's documents convert it to another entity in a crisis, the new entity's rules govern, so read that section of the offering documents.
What happens if I miss a capital call?
The partnership agreement's default remedies apply. In the opportunity fund filing they include forfeiting voting rights and a substantial portion of your interest or having your undrawn commitment cancelled.
Does a capital call affect my tax basis?
Yes. Under section 722 the basis of a partnership interest acquired by contribution equals the money and the adjusted basis of property contributed, so each funded call adds to basis.
