2026 IRS Inflation Adjustments: What Tax Pros Need to Know Now

The IRS dropped the 2026 inflation adjustments in May, and they're worth your immediate attention. Tax brackets are moving higher, standard deductions are jumping, and capital gains thresholds are shifting. This isn't optional reading — it's the foundation for planning the next 6–8 months of client conversations.

The Numbers That Matter

Standard Deductions (up across the board):

• Married Filing Jointly: $32,200 (up from $29,200 in 2025)
• Single: $16,100 (up from $14,600)
• Head of Household: $24,150 (up from $21,900)
• Age 65+: Additional amounts for all filing statuses

This 2–3% bump covers inflation. For your clients, it means itemized deductions have to clear a higher hurdle to make sense. Review client deduction stacks now — some who itemized in 2025 might fall back to the standard deduction in 2026.

Tax Brackets — Everyone Moves Up: Marginal rates stay the same (10%, 12%, 22%, 24%, 32%, 35%, 37%), but the thresholds shift higher. A filer who paid 24% on income above a certain threshold in 2025 might not hit that bracket until higher income in 2026. Run the numbers for your high-income clients — some planning opportunities might have opened up.

Capital Gains — New Long-Term Thresholds: Long-term capital gains rates (0%, 15%, 20%) are tied to income thresholds. Those thresholds adjusted for inflation. The 15% bracket now kicks in at higher income levels than 2025. Clients sitting on appreciated assets should reassess sale timing.

Estate Tax Exemption: $15 Million: The federal estate tax exemption climbed to $15 million per person (from $13.61 million). For estates near this threshold, it's planning season. Portability elections, strategic gifting, and trust reviews are back on the menu for clients with net worth in the $25M+ range.

Retirement Contribution Limits & Credits:

• 401(k) contributions: $24,500 (up from $23,500)
• IRA contributions: $7,000 (unchanged from recent years, but dependent contributions limit increased)
• EITC: $8,231 max (up from $7,430)
• Adoption credit: $17,670 (up from $16,810)

Translation: More room to shelter income for clients running solo practices or small firms. More value in EITC planning for certain business structures.

What This Means For Your Firm

1. Refresh Your Planning Conversations (Now) Don't wait until October. The old brackets are obsolete. Pull together your client list for 2026 projected income, and run scenarios. What changes? Who benefits from deferring or accelerating income? Which clients should be thinking about charitable contributions, loss harvesting, or retirement plan changes?

2. Reassess Itemization Strategies The higher standard deduction floors out more taxpayers. If a client was itemizing by a narrow margin in 2025, they might not itemize in 2026 — which changes state and local tax (SALT) planning, charitable bunching, and mortgage interest deductions.

3. Capital Gains Planning Heats Up Higher thresholds open new windows. A client selling an investment property or business stake might now be able to pack two years of transactions into a single favorable bracket. Conversely, clients with passive gains in portfolio accounts need to review expected gains in 2026.

4. Estate & High-Net-Worth Clients The $15M exemption is breathing room, but it's not forever. If you're advising anyone with serious assets, now is the time to talk portability elections, annual exclusion gifting strategies, and whether irrevocable trusts or dynasty structures make sense. The window is open — it may not stay that way.

Action Items for Your Workflow

• Update your tax return templates — plug in 2026 brackets, standard deductions, and phase-out thresholds. Test them with a few 2026 projections.
• Flag clients for outreach — those with itemized deductions near the new thresholds, high earners, business owners with capital gains, and estates over $10M net worth.
• Review prior-year returns — any client you amended in 2025 (especially for estimated tax shortfalls or NOL carryforwards) needs a checkup for 2026 impact.
• Document your planning strategy — if you recommend bunching charitable gifts or deferring gain into 2026 for a better bracket, write it down now. Protects you and the client.

The Bottom Line

2026 adjustments aren't earth-shattering, but they're not negligible. Collectively, they open planning doors that didn't exist in 2025. Tax pros who digest these numbers this month and act on them with clients will stand out — everyone else will scramble in Q4 when it's too late.

Read the full IRS guidance (Revenue Procedure 2025-32) if you need specifics on earned income credits, AMT thresholds, or contributions limits. The official numbers are authoritative. Everything else is interpretation — and that's where your value lives.

Start with three conversations this week. Pick your most engaged clients and walk them through the numbers. You'll spot planning opportunities they didn't know existed.
