M&A Tax Lawyers in 2026: Rising Demand, Local Benches

M&A tax lawyers lateral hiring is rising, and it is staying at home. Sartori & Partners data show that 180 lawyers whose focus is corporate and M&A tax joined a new firm in the 12 months to October 2026, and that only 12.0% of them changed city along the way. Across the tax practice the figure was 21.1%, and across the whole lateral market 20.5%. On the settled year, hiring in the specialty rose 22.6%, from 155 to 190 moves. More hires are being made, and a smaller share of the lawyers who do move are prepared to relocate for the seat. For a firm that needs transaction tax capacity, the practical market is the bench already sitting in its own city.

The gap is wide for a specialty that sits inside the tax practice. The corporate and M&A tax share of city changers sits 9.1 points under the tax practice and 8.5 points under the market. The measure counts only moves where both the old and the new city are known, so it describes how lawyers move, not how many. Nor is this a one-year accident. Over 3 years, 15.5% of M&A tax movers changed city, against 22.6% in tax and 21.6% in the market. Set against those 3-year levels, the latest 12 months read 3.5 points lower for the specialty, 1.5 points lower for tax and 1.1 points lower for the market. The specialty was already local, and it has become more so.

There is a plain reason in the work. A tax lawyer who structures acquisitions sits inside the deal teams, sponsors and corporate clients of one city, and that network rarely survives a relocation intact. For the hiring firm, a relocation pitch starts at a disadvantage, and a search that counts on candidates moving in from another city will run long. Build the long list from the city where the seat sits.

In the Sartori & Partners lateral database, corporate and M&A tax hiring rose 22.6% over the settled 12 months to September 2026, from 155 to 190 moves. Tax hiring as a whole rose 23.8%, from 592 to 733. Hiring across the market rose 9.0%, from 13,128 to 14,305. The specialty moves with its practice, and both run well ahead of the market. Calendar years point the same way: 158 M&A tax lawyers had moved in 2026 by the end of October, already past the full 2025 count of 155.

Partner hiring needs more care. Settled partner arrivals in the specialty went from 68 to 87, a gap that chance alone can produce on counts this small, so the partner count held flat (+27.9%) by our noise test. The firm-level reading is plain all the same: more hires are being drawn from a pool that, as the first section showed, does not travel. That means more rival offers on each candidate, so a firm that delays a search meets stiffer competition, not a deeper bench.

Location counts for more in a specialty that stays put. New York took 16.7% of corporate and M&A tax lateral moves in the 12 months, an index of 113 against the market's city mix. London took 11.1%, an index of 120. Tax as a whole reads below the market in both cities, at 93 in New York and 94 in London, so the pull of the two financial centers is specific to deal tax work. Over 3 years London carried 15.6% of M&A tax moves, New York 12.2%, Paris 7.0% and Washington, DC 4.8%.

Put the two findings together and the map is clear. The deepest benches sit in New York and London, and corporate tax movers seldom change city. A firm with an established tax group in either city should recruit there first, where most candidates already work. A firm building a transaction tax seat in a third city should plan around a local hire, or a local associate it trains into the role, rather than a partner imported from one of the two centers.

Firms of 1,000+ lawyers took 58.3% of corporate and M&A tax hires, against 49.9% across tax and 53.6% across the market. Firms under 150 lawyers took 4.4%, against 10.1% in tax. Hiring is concentrated as well: the top 10 hirers took 28.9% of M&A tax laterals, against 16.4% in tax and 12.9% in the market, and at partner level the top 10 took 35.7%, against 20.3% in tax. White & Case, CMS and DLA Piper head the 12-month list, each in the 6-10 band of individual hires.

The deal record explains the pull of large platforms. Sartori & Partners deal records hold 119 dated deals with corporate and M&A tax work over 3 years. M&A was the deal type on 45.4% of them, and financial sponsors were a client industry on 23.5%. Sponsor work repeats with the same funds and deal teams, which binds a tax lawyer to a city and a platform. A firm bidding for a sponsor-side tax lawyer competes with the large hirers on this list and with the candidate's local client ties at the same time.

Partners were 46.7% of corporate and M&A tax laterals in the 12 months, against 37.9% across tax and 27.7% in the market. Associates were 42.2%, against 48.5% in tax. Few arrive with a title step: 13.9% joined at a higher title than the one they left, against 15.5% in tax and 12.9% in the market. Firms also make these partners themselves: in the same records, 51 corporate and M&A tax lawyers were promoted to partner from June 2025 to May 2026, the latest window in which promotions are confirmed. The median promotion came 10.0 years after the first year of practice, and the middle half took between 8.0 years and 12.0 years.

The candidate profile follows. A firm that needs deal tax capacity this year is hiring a sitting partner, in most cases in the city where it wants the seat and with clients tied to that city. A firm that can wait a decade can grow its own, but the associate share of movers is lower here than in tax, so the junior pool is thinner too.

Start local. With only 12.0% of corporate and M&A tax laterals changing city, the candidates for a seat are, in most cases, already working in that city. Recruit in New York and London first if the seat can sit there; the indexes of 113 and 120 mark the deepest benches. Expect competition from a small group of large platforms, which took 28.9% of the specialty's hires through their top 10. Demand is visible on the open market too: on the data date, law-firm career pages listed 243 open roles in corporate and M&A tax. Move early: a delayed search meets the same local pool with more bidders on it. Where the seat must sit in a third city, budget for a longer search, consider a local associate with deal exposure, and plan to train that lawyer into the role rather than wait for a partner to relocate.
