Many angels invest in their own name, because the main tax benefits for startup stock, QSBS and Section 1244 losses, work most simply for individuals. An LLC taxed as a partnership can pass QSBS through and suits people pooling money. A C corporation loses QSBS. Retirement accounts swap those benefits for tax deferral or tax-free growth.
What are the main ways to hold angel investments?
There are fewer real options than the internet suggests, and each one changes how the tax rules for startup stock apply to you.
In your own name, alone or jointly with a spouse.
A single-member LLC. For income tax, the IRS ignores it by default and treats its assets as yours.
A multi-member LLC or limited partnership taxed as a partnership, which files its own return and sends each owner a K-1.
An S corporation, also a pass-through entity, with tighter rules on who can own it.
A C corporation, which pays its own tax.
A retirement account, such as a self-directed IRA, a Roth IRA or a solo 401(k), through a custodian that allows private stock.
A trust, usually as part of estate planning.
Investing through someone else's syndicate SPV is a different thing: you own an interest in their LLC rather than choosing your own structure. How that works is in the guide to angel investing syndication.
This guide explains how each option interacts with the rules. It is not advice for your situation; a tax adviser who knows your finances should make that call.
How does each structure treat QSBS?
Qualified small business stock (QSBS) under Section 1202 is the largest tax benefit in angel investing. It lets a non-corporate holder exclude gain on stock bought at original issuance from a qualifying C corporation. For stock issued after July 4, 2025, the One Big Beautiful Bill Act allows a 50% exclusion after three years, 75% after four and 100% after five, with a per-company cap of $15 million or ten times your basis, whichever is greater. Older stock needs five years and has a cap of $10 million or ten times basis. The full rules are in the guide to angel investing tax benefits.
Structure changes who gets that exclusion:
In your own name: the simplest case. You buy at original issuance and the holding period is yours.
Single-member LLC: because the LLC is disregarded for income tax, it is generally treated as if you held the stock yourself.
Partnership or S corporation: Section 1202(g) of the Internal Revenue Code passes the exclusion through to owners, but only to those who held their interest when the entity bought the stock and kept it the whole time, and only up to their interest at that date. IRS Publication 550 applies the same rule to pass-through entities (partnerships, S corporations and regulated investment companies) for the related Section 1045 rollover: you benefit only if you held your interest for the entire period the entity held the stock.
C corporation: Section 1202 only applies to taxpayers other than corporations, so stock held by your C corporation gets no exclusion, and profits paid out to you are taxed a second time.
Retirement account: gains are already deferred or, in a Roth, tax-free, so QSBS adds nothing.
Trusts: a non-grantor trust is a separate taxpayer with its own cap, which is why estate planners use them. The rules are complex and include anti-abuse provisions; this is specialist territory.
One trap catches people who restructure later. Only certain transfers keep QSBS status, such as gifts, inheritance and distributions from a partnership to its partners. Contributing stock you already own to a multi-member LLC is not one of them, so moving existing positions into a new entity can cost you the exclusion.
How does each structure treat losses?
Most angel checks lose money, so loss treatment matters as much as gain treatment.
Capital losses offset capital gains, and individuals can deduct up to $3,000 a year of net capital loss against ordinary income, carrying the rest forward. Section 1244 does better for qualifying stock: according to IRS Publication 550, an original owner can deduct up to $50,000 a year as an ordinary loss, or $100,000 on a joint return. The same publication says the stock must be issued to the person taking the loss; through a partnership, you must have been a partner when the stock was issued and remained one, and stock the partnership distributes to you loses ordinary-loss treatment.
A C corporation can't use Section 1244 at all, and losses inside a retirement account can't be deducted.
Does an LLC protect you from liability as an angel?
Less than people expect. As a minority shareholder in a corporation, your exposure is generally limited to what you invested; a failed startup's creditors don't come after its passive shareholders. An LLC adds little to that for a portfolio of passive stakes. It matters more if several people invest together and want clear rules between them, or if you run an investing activity with contracts and obligations of its own. A board seat creates duties of its own, which an LLC doesn't remove; that is what directors and officers insurance is for.
What an entity costs to run
Formation and annual fees. These vary by state. California, for example, charges LLCs an $800 minimum annual tax.
Separate tax returns. A multi-member LLC files a partnership return and issues K-1s every year.
Separate banking and books, which some investors want anyway.
Paperwork on every deal. Each SAFE, cap table entry and know-your-customer check goes in the entity's name.
Accredited status. An entity is accredited if it has more than $5 million in assets and was not formed to make the specific investment, or if every equity owner is accredited, which usually covers an LLC owned by accredited people.
If you're still sizing your first checks, how much money you need to start angel investing comes before any of this. For the founder-side version of this question, see how to choose the right legal structure for a startup. More guides are in the angel investing section.
Where each structure tends to fit
Personal ownership is the default for one person writing checks: the simplest QSBS and Section 1244 treatment and no extra filings.
A single-member LLC suits someone who wants investing kept separate on paper, with tax results that generally track personal ownership.
A multi-member LLC or LP suits family members, partners or a small group pooling money under one set of rules, at the cost of a partnership return.
Trusts belong in an estate plan drawn up with a specialist.
A C corporation rarely fits startup stock, because it forfeits QSBS.
A retirement account suits money that is already there, with care around prohibited transactions and the loss of any deduction for failures.
Frequently Asked Questions
Q:Does investing through an LLC protect me if a startup fails?
Usually it changes little. As a passive minority shareholder, your loss is generally limited to what you invested whether or not you use an LLC. An LLC helps more with organizing shared money and record-keeping than with liability.
Q:Can I get QSBS if I invest through an LLC?
A single-member LLC is generally treated as you for income tax. A multi-member LLC taxed as a partnership can pass QSBS through to members who held their interest when it bought the stock, under Section 1202(g). An LLC that elected to be taxed as a C corporation cannot.
Q:Can I use my IRA for angel investments?
Some custodians allow private startup stock in a self-directed IRA. Gains grow tax-deferred, or tax-free in a Roth, but losses can't be deducted, QSBS doesn't apply, and prohibited-transaction rules bar deals that benefit you or close family directly.
Q:Is an LP better than an LLC for angel investing?
For most small groups an LLC is simpler and works the same way for tax. Limited partnerships are more common for formal funds with a general partner and passive limited partners. Both are pass-through entities when taxed as partnerships.
Q:Can I move my existing angel investments into an LLC later?
You can, but it may cost you. Contributing stock to a multi-member LLC is not one of the transfers that keeps QSBS status, and stock later distributed back to you from a partnership loses Section 1244 treatment. Get tax advice before moving positions you already hold.
