Hedge Fund Manager or RIA: LLC or S Corp After Soroban?

Why separate the management fee from the GP’s carry?

The management company earns service fees; the general partner, or GP, may receive fund partnership profits called carry. Their tax treatment can differ; see investment-management rules and partnership profits interests.

An LLC is a legal entity, while partnership or S corporation status describes its tax treatment. An eligible LLC can elect S corporation taxation without replacing the LLC with a state-law corporation. See the IRS election instructions.

Partnership treatment lets the GP use qualifying profits interests and flexible partnership allocations. An S corporation cannot issue a partnership profits interest in itself; its shares have identical distribution and liquidation rights. The GP can remain a partnership when the fee company elects S status.

Holding carry through an S corporation does not remove the three-year holding-period rule; see carried interest and the three-year rule and the corporate-exception regulation.

How do a partnership LLC and an S corporation compare?

A partnership offers flexible ownership and profit sharing. An S corporation separates salary from remaining business income, but changes ownership restrictions and local taxes.

For PTET coverage and residence tests, see New York’s calculations, City PTET rules and PTET elections. For MCTMT, compare partner earnings with employer payroll.

For this year’s K-1 box 14, see self-employment tax for fund managers after Soroban.

Public Law 119-21 made QBI permanent; see IRS Publication 334. Investment management is a specified service business: above the applicable taxable-income phase-in range, its income does not qualify for QBI under either structure. Electing S status does not remove that limit. See the specified-service regulation, fund-management QBI eligibility and QBI calculations.

What salary must portfolio managers receive, and what can that save?

An S corporation must pay working portfolio managers reasonable compensation for their services before treating owner payments as distributions; use the owner salary guide and the IRS compensation rules.

For owners whose proposed salary reaches the Social Security wage base of $184,500, the saving is mostly Medicare tax: 2.9%, plus 0.9% Additional Medicare tax above the personal threshold. See SSA, self-employment tax rates and Additional Medicare rules.

If salary also exceeds that threshold and the fee profit would otherwise bear self-employment tax, estimate the Medicare reduction as (2.9% + 0.9%) × (92.35% of the owner's partnership profit share − proposed salary). The factor comes from Schedule SE. This is before employer payroll deductions and other income-tax effects.

Salary bears employer and employee Medicare tax. Include other wages, payroll costs and deductions in the full model; another employer's wages do not automatically eliminate the company's employer Social Security cost (Publication 15). S pass-through income is not self-employment income, but owners report it even if retained (Form 1120-S instructions).

Does New York City GCT cost more than UBT?

New York City can outweigh the federal employment-tax benefit. A federal S corporation is, in general, subject to GCT, and the City does not recognize the New York State S election. See NYC Finance.

GCT starts with the largest result from four bases. For an ordinary management company, the comparison is:

See the City rate schedule and NYC-3L instructions. Subsidiary capital can add a separate tax of 0.075%. These figures use the latest annual City instructions; check exceptions, short-year rules and filing-year updates.

A taxable partnership management company instead pays UBT at 4%. Payments for partners’ services are not ordinary salary deductions for UBT. The services allowance is limited to the smaller of 20% of the relevant net income or $10,000 per active partner; the partnership also has a $5,000 full-year specific exemption. See NYC-204 instructions.

Can each partner own their interest through an S corporation?

A management partnership can have S corporations as partners: the individual owner receives salary and S pass-through income, which is not self-employment income. Partnership allocations remain available, but each corporation adds payroll and returns. See Publication 541 and 1120-S instructions.

Each corporation receives the management partnership’s federal K-1 and, where required, New York corporate-partner K-1, pays reasonable owner salary, and issues shareholder K-1s. See CT-3-S and 1120-S instructions. Review contracts and transfers before assigning a personal partnership interest to a corporation.

A corporate partner cannot pass New York PTET credits to its owners. The management partnership excludes income flowing to an S corporation. Each eligible New York S corporation must elect separately for its shareholders’ qualifying income, including partnership income after deductible salaries; wages are excluded. Each corporation opts in annually online by March 15 if it wants PTET; see New York’s PTET FAQ and PTET election steps.

An S corporation partner taxable under City GCT adds that tax while the management partnership continues paying UBT. Model the corporate partner’s available UBT-paid credit on Form NYC-9.7 rather than simply adding both taxes at their full rates; the NYC-3L instructions limit that credit to the income-based calculations. The individual owner loses IT-219 because the corporation is now the partner. A company-wide S election ends UBT and that credit; see IT-219 instructions.

Can an S corporation split fee profits unevenly or admit a new partner?

An S corporation cannot allocate fee profits independently of share ownership. All outstanding shares must confer identical distribution and liquidation rights, although voting rights can differ. See the one-class-of-stock regulation.

Reasonable salaries or bonuses can compensate different work. Equal shareholders still need identical contractual rights to residual profits. Review any agreement that assigns profit by strategy, client book or negotiated annual sharing before electing.

Stock given for services generally creates taxable pay equal to value at vesting minus any amount paid (section 83 regulation); a qualifying partnership profits interest generally is not taxed at grant. For unvested stock, the recipient can elect taxation at transfer on Form 15620 or a compliant section 83(b) statement within 30 days after transfer; see Form 15620 and becoming a fund-manager partner. Check eligibility before any transfer.

Which foreign partners, trusts or holding LLCs block the election?

A nonresident alien, a partnership or an ordinary corporate shareholder generally blocks the management company’s S election. Canadian nationality or living abroad alone does not answer the question; determine each owner’s US tax status. For the general eligibility rules, see whether to elect S status and IRS requirements.

Required QSST and ESBT elections use the 16-day-and-2-month period starting with the stock transfer; for a trust holding stock before the company elects S status, it starts with the S effective date if the company elects that year, or the filing date if it elects for the following year. Use Form 2553 Part III where applicable or a compliant election statement; a missed required election can invalidate or terminate S status. See the trust rules and late-election relief.

Partner-owned S corporations can own a management partnership. They generally cannot be shareholders of an S corporation management company.

How and by when can a partnership switch for next year?

An eligible management LLC generally elects S taxation and corporate classification on Form 2553, signed by an officer with all required shareholder consents. New York generally requires CT-6 signed by an authorized person and every required shareholder; see IRS instructions and New York instructions.

Weekend and legal-holiday deadlines move to the next business day. Without CT-6, unless S status is mandated or relief is granted, New York taxes the company as a C corporation: the company pays corporate franchise tax, resident owners pay tax on distributions, and New York PTET is unavailable (State rules). Tax Law § 660(b)(5) permits reasonable-cause late-election relief; CT-6 instructions also describe validation following federal relief.

For a non-calendar year, Form 2553 is ordinarily due within 2 months and 15 days after the year begins. New York can mandate S treatment if qualifying investment income exceeds 50% of federal gross income, including specified items from partnerships; management service fees alone do not establish that test. See CT-3-S instructions.

A qualifying conversion is usually tax-free, but assumed debt above the adjusted basis of transferred assets can create gain, subject to exceptions; see changing business structure, IRS Publication 542 and the liability rules.

Returning to partnership taxation can involve a taxable deemed liquidation; the classification regulation generally bars another classification election for 60 months after an existing LLC changes classification. Losing S eligibility, such as through an ineligible share transfer, leaves corporate classification in place: the company becomes a C corporation. Without IRS consent, S reelection generally waits until the fifth tax year after the first tax year in which termination took effect (1120-S instructions); inadvertent termination relief may apply. If the deadline was missed, use late S election relief.

What extra returns and costs come with S status?

S status usually adds owner payroll, corporate returns and payroll administration. A company-wide election replaces the management partnership return; partner-level elections keep that return and add separate corporate returns.

See IRS S corporation filings, New York CT-3-S and City GCT forms. For general election and administration costs, see whether to elect S status.

The federal late Form 1120-S penalty can apply even when the corporation owes no income tax: $260 per shareholder per month or part of a month, up to 12 months, absent reasonable cause. The current filing-year amount comes from Revenue Procedure 2025-32, section 4.56; the return instructions explain the penalty mechanics. New York also charges $50 per shareholder per month or part-month, up to 5 months, for a late or incomplete CT-3-S (CT-6 instructions).

Officers or others responsible for withheld payroll taxes who willfully fail to pay them can personally owe 100% of the unpaid trust-fund taxes under IRC § 6672 (Publication 15). Assessment generally has a 3 years limit from the later of filing or the succeeding April 15; unfiled returns have no limit. Collection generally lasts 10 years after assessment, subject to extensions and suspensions (IRS manual).

Under either structure, eligible owners can personally owe their share of unpaid New York PTET. Managing or controlling owners and the election maker can owe the entire tax (Tax Law § 866(c)). Collection generally ends 20 years after a warrant could first be filed; a warrant generally must be filed within 6 years after assessment, subject to statutory exceptions (§ 174-b).

Does the same choice apply to an RIA managing separate accounts?

An investment adviser managing separate accounts uses the same comparison for its fee business. Without a fund partnership allocation, there is no GP carry structure; contractual performance fees remain service-fee income. The investment-management regulation covers fees for asset management and investment advice.

Example

Assume three active New York City resident owners with equal shares and an annual management-fee profit of $3,000,000 before owner compensation and City business tax. All amounts are illustrative US dollars. All business income is allocated to the City, and there are no other adjustments or credits in the entity-level comparison.

Assume the capital and minimum-tax bases are smaller and there is no subsidiary capital. On these simplified inputs, GCT exceeds UBT by $14,150 before considering federal employment taxes or owner-level credits. The calculation follows NYC-204 and NYC-3L.

If each owner's City taxable income is at least $142,000 and their City tax liability allows the full credit, IT-219 credits total $27,278 (23% × $118,600). The City gap then becomes $41,428 ($132,750 − ($118,600 − $27,278)); see IT-219.

Assume each owner also exceeds the Additional Medicare threshold under both structures. Before business-tax deductions, the Medicare reduction is $48,279: 3.8% × ($3,000,000 × 92.35% − $1,500,000). Deducting UBT from partnership profit reduces that estimate to about $44,117: 3.8% × (($3,000,000 − $118,600) × 92.35% − $1,500,000). These isolated comparisons do not decide the election.

The full model must include employer payroll taxes and deductions, PTET, State taxes and MCTMT on partner earnings or payroll. The assumed salaries do not establish reasonable pay.

Different for you?

• The management business operates in New York City: request a model of salaries and New York State and City taxes through hedge fund tax services. Gather the operating agreement, fee and carry split, payroll, last NYC-204, owner residence details and any corporate returns.
• The company is outside New York City: compare your state’s taxes on each structure. California, for example, taxes S corporations at 1.5% of California net income; see whether to elect S status.
• An owner lives abroad: verify shareholder eligibility and withholding through a company with a foreign co-owner; use hedge fund tax services before changing the ownership structure.
• An owner lives in Canada: start with Canadian ownership of a US LLC, and obtain a coordinated ownership review through hedge fund tax services.
• An existing partnership has debt, uneven allocations or incoming partners: review changing business structure and use hedge fund tax services before filing an election. Gather asset tax basis, liabilities and proposed ownership terms.
• The real question is a C corporation: use LLC or C corporation for that separate comparison.
• The election deadline has passed: use late S corporation election relief.
