Charitable Giving Strategies for Big Law Attorneys: 2026 Guide

Big Law equity partners are among the most charitable professionals in the country — partly out of genuine generosity, and partly because the tax math at 37% + 13% state is so compelling. But the OBBBA changed the rules starting in 2026, and most generic charitable planning guides haven't caught up. Here's what changed, what still works, and how to sequence giving around K-1 income and NQDC distributions.

What OBBBA changed for charitable deductions in 2026

Two new limits apply to itemized charitable deductions starting with the 2026 tax year:

1. The 0.5% AGI floor

Charitable contributions are now only deductible to the extent they exceed 0.5% of your adjusted gross income.¹ For a partner with $1M AGI, the first $5,000 of giving is effectively non-deductible — it just clears the floor. For a partner with $600K AGI, the floor is $3,000. This reduces the tax efficiency of small, scattered donations but has minimal impact on donors giving meaningful amounts.

2. The 35% deduction benefit cap for 37% bracket taxpayers

If your marginal tax rate is 37%, your federal deduction benefit on itemized charitable contributions is capped at 35 cents per deductible dollar — not 37 cents.¹ For a partner with $1M+ in K-1 distributions, this 2-point spread costs approximately $200 in federal tax savings for every $10,000 donated above the floor. On a $100,000 gift (a meaningful gift for a senior partner), the cap costs $2,000 in federal savings versus pre-OBBBA rules.

What didn't change: the 60% AGI limit for cash donations and 30% limit for appreciated property are unchanged. QCDs are unchanged. And the core economics of donating appreciated securities rather than cash are fully intact — in fact, with the OBBBA cap in place, the appreciated securities advantage grows in relative importance.

Strategy 1: Donate appreciated securities — still the most powerful tool

For equity partners who've held appreciated public securities — accumulated during years of investing partnership distributions — donating appreciated stock to charity (directly or via a donor-advised fund) eliminates the embedded capital gains tax entirely while generating a full FMV deduction.²

Here's why this beats writing a check, even under the OBBBA cap:

• You get a deduction equal to FMV — the same deduction as donating cash of the same amount, subject to the 30% AGI limit and the same 0.5% floor/35% cap.
• You avoid capital gains tax on the embedded gain. At the top federal LTCG rate of 20% plus 3.8% NIIT = 23.8%, a $50,000 position bought at $20,000 has $30,000 in embedded gains and would generate $7,140 in federal tax if sold. Donate the position instead and that $7,140 stays in your pocket. State capital gains taxes (often 10-13% in NY/CA) add further savings.
• You can immediately repurchase equivalent exposure at a higher basis, reducing future capital gains liability.

One constraint: appreciated property donations are limited to 30% of AGI per year (vs. 60% for cash).² Contributions above the 30% limit may be carried forward for up to five years. Partners planning a large single-year gift should verify the limit before year-end.

Strategy 2: Donor-Advised Fund — bunching for variable K-1 income

Big Law equity partner income is variable. In a good firm year, PEP jumps $300K–$500K over the prior year. In a downturn year, distributions contract. This income variability creates a natural tax-planning opportunity: front-load charitable contributions in high-income years using a donor-advised fund (DAF).

A DAF is a charitable account — typically at Fidelity Charitable, Schwab Charitable, or Vanguard Charitable — where:

• You contribute cash or securities and take the full charitable deduction in the year of contribution (subject to limits).
• The funds are invested tax-free within the DAF.
• You recommend grants to 501(c)(3) organizations at any time — years later if you prefer.

The bunching math under OBBBA

Suppose you give $20K/year to charitable causes. Under the OBBBA 0.5% floor (with $800K AGI, floor = $4,000):

• Give $20K annually for 5 years: Each year deductible = $16,000 × 35% = $5,600. Total 5-year deduction value: $28,000.
• Bunch 5 years into one DAF contribution of $100K: Year-1 deductible = $96,000 × 35% = $33,600. The remaining 4 years you give $0 and claim the $2,000 non-itemizer deduction. Total deduction value: $33,600 — gaining $5,600 over spreading the gifts, plus the DAF's invested growth on ungranted funds.

The bunching advantage is amplified when you're in the 37% bracket in years where K-1 income spiked — say, a firm record-profit year or a year you received a partner promotion signing bonus. Use those high-income years to pre-fund 3–5 years of charitable giving in one deductible contribution, even if you continue granting the charities the smaller annual amounts they're used to receiving.

Fund the DAF with appreciated securities, not cash

The most efficient approach: contribute appreciated securities to the DAF. You get the same FMV deduction. The DAF sells the shares without paying capital gains tax (it's a 501(c)(3)). The full $50K of value — not $50K minus capital gains — is available to invest and grant. This combines the appreciated securities advantage with the bunching strategy.

Strategy 3: Qualified Charitable Distribution (QCD) — for partners approaching 70½

Partners who've built substantial traditional IRA balances — through decades of 401(k) contributions and potential rollovers — face RMDs beginning at age 73 (for those born 1951–1959) or 75 (born 1960 and later) under SECURE 2.0.³ These distributions are taxable ordinary income and can push a retirement-era partner into higher IRMAA brackets.

A Qualified Charitable Distribution (QCD) allows anyone 70½ or older to transfer up to $111,000 directly from their IRA to a qualified charity in 2026.⁴ The QCD:

• Counts toward the RMD for the year — reducing taxable distributions dollar for dollar.
• Is excluded from gross income entirely — it never flows through AGI at all, bypassing the OBBBA 0.5% floor, the 35% cap, and the 30% appreciated property limit.
• Lowers AGI, which can reduce IRMAA surcharges, increase the §199A QBI deduction phase-in range, and reduce taxation of Social Security.

For a retiring equity partner at age 72 with $1M in a traditional IRA and a $60K RMD looming: directing $50K as a QCD turns $50K of taxable income into a tax-free charitable gift. At a 37% combined marginal rate, that's $18,500 in tax avoided — all without touching the OBBBA deduction rules.

Timing giving with K-1 income and NQDC distributions

For active equity partners, the highest-value years to give are the years where income peaks. Two situations in particular:

• Record firm-profit years: PEP spiked, you're at maximum 37% marginal exposure. Pre-fund 3–5 years of giving into a DAF with appreciated securities before December 31.
• NQDC distribution years: Deferred compensation under §409A fires as ordinary income in the year elected. These distributions can add $200K–$500K+ to taxable income in a single year. Large DAF contributions in NQDC distribution years absorb income that would otherwise be taxed at 37%. Coordinate the gift size against your projected AGI — but be careful of the 60% cash / 30% appreciated assets limits. See our NQDC optimizer for distribution timing scenarios.
• Departure year: Capital account returns, NQDC distributions, and possibly consulting income converge. If you've been building up a DAF or have appreciated positions to donate, the departure year is often an optimal one. See our Leaving Big Law guide for the full income stack model.

What this requires in practice

Tax-efficient charitable giving for Big Law attorneys isn't hard mechanically — open a DAF account (takes 15 minutes), fund it with appreciated positions, and give grants as you would anyway. The complexity is in the coordination:

• Which appreciated positions to donate, and in which order, affects your portfolio basis and future capital gains exposure.
• NQDC distribution years, departure years, and spike-income years require advance planning — you can't retroactively bunch into last year's income.
• The 30% AGI limit on appreciated assets requires sizing the contribution against your projected AGI before year-end, especially in variable-income years.
• For large estates, charitable giving interacts with the $15M OBBBA exemption, SLAT structures, and the charitable deduction for estate purposes — see our estate planning guide.
