Max out 401(k) and HSA
- Tax planners in 2026 are steering high earners first to plain-vanilla shelters: max workplace retirement plans and health savings accounts before trying residency moves, private-placement insurance, or other bespoke structures. - The hard numbers changed this year: the Internal Revenue Service set the 2026 401(k) deferral limit at $24,500 and the 2026 health savings account cap at $4,400 single or $8,750 family. - More aggressive ideas still carry filing and audit risk, especially Puerto Rico residency and expatriation moves that trigger Form 8898 or Form 8854 and strict residency tests.

For 2026, the simplest tax advice for high earners is still the first advice: fill up the 401(k) and the health savings account before chasing exotic shelters. (irs.gov 1) (irs.gov 2) The Internal Revenue Service raised the employee deferral limit for 401(k), 403(b), most 457 plans, and the federal Thrift Savings Plan to $24,500 for 2026, up from $23,500 in 2025. Workers age 50 and older can generally add an $8,000 catch-up, bringing the total to $32,500. (irs.gov) The 2026 health savings account limit is $4,400 for self-only coverage and $8,750 for family coverage, with a separate $1,000 catch-up for people 55 and older. Those accounts are available only with qualifying high-deductible health plans. (irs.gov) That ordering matters because both accounts are written directly into the tax code, payroll systems, and annual Internal Revenue Service inflation adjustments. They do not depend on proving a move, defending an appraisal, or sustaining a novel legal position in an audit. (irs.gov 1) (irs.gov 2) After those basics, donor-advised funds are one of the more common timing tools. Internal Revenue Service Publication 526 says a donor-advised fund is an account where the donor can advise how money is invested or distributed, while claiming a deduction subject to the usual charitable-contribution rules. (irs.gov) That makes donor-advised funds useful for bunching gifts into one tax year, especially after a bonus, stock sale, or other spike in income. The deduction timing can move faster than the grants to working charities, which may go out over several years. (irs.gov) Residency strategies are a different category. The Internal Revenue Service says territory tax treatment turns on whether a person is a bona fide resident under Internal Revenue Code Section 937, and people who begin or end that status may have to file Form 8898. (irs.gov 1) (irs.gov 2) Puerto Rico gets the most attention, but the Internal Revenue Service rules are narrower than social-media pitches suggest. Publication 570 says sourcing rules, physical presence tests, and filing obligations determine whether income is excluded from a U.S. return or still taxed federally. (irs.gov) (irs.gov) Leaving the U.S. tax system altogether is narrower still. The Internal Revenue Service says people who expatriate after June 4, 2004 use Form 8854, and covered expatriates can face an exit-tax regime tied to worldwide assets and compliance tests. (irs.gov) The through line is less glamorous than the online sales pitch. In 2026, the cleanest tax savings still start with the annual limits the Internal Revenue Service already published, and the riskier moves start where extra forms and residency tests begin.
