Maximizing 2026 Tax Laws: Your Comprehensive Planning Guide

The 2026 tax year is shaping up to be the most consequential planning window in nearly a decade. Three major forces are converging simultaneously: the One Big Beautiful Bill Act (OBBBA) extending and expanding TCJA provisions, a historic estate and gift tax exemption cliff, and a wave of SECURE 2.0 Act provisions fully taking effect. Each creates both opportunity and risk depending on how you act — or fail to act — before year-end.

This guide covers what changed, who it affects, and the specific strategies to maximize each provision.

The One Big Beautiful Bill Act extended and in several cases enhanced the core provisions of the 2017 Tax Cuts and Jobs Act (TCJA), which were originally set to expire after 2025. Rather than allowing a broad sunset, Congress acted to make many provisions permanent or extend them through the early 2030s.

Bonus Depreciation — Restored to 100%

One of the most impactful provisions for business owners and real estate investors: bonus depreciation is restored to 100% for qualified property placed in service in 2026 and beyond.

Under the original TCJA phase-down schedule, bonus depreciation had stepped down to 40% in 2025 and was scheduled to reach 20% in 2026 before expiring entirely. The OBBBA reverses this — 100% first-year expensing is back.

What qualifies:

• Machinery and equipment with a recovery period of 20 years or less
• Qualified improvement property (QIP)
• Computer software
• Certain film, television, and live theatrical productions
• Personal property components identified in a cost segregation study

Strategy: If you have been deferring a cost segregation study waiting for clarity on bonus depreciation, 2026 is the year to act. A study completed and placed in service in 2026 can generate 100% first-year deductions on all reclassified personal property and land improvements — the maximum possible benefit.

Section 179 Expensing — Expanded Limits

The Section 179 deduction limit has been increased and indexed for inflation under the OBBBA. For 2026, the deduction limit is $1,220,000 with a phase-out beginning at $3,050,000 in total property placed in service.

Unlike bonus depreciation, Section 179 cannot create a loss — it is limited to taxable income from active business. However, it offers flexibility: you can elect the exact amount you want to deduct rather than taking an all-or-nothing approach.

Strategy for small business owners: Use Section 179 to dial in your taxable income to a specific bracket, then layer bonus depreciation on top for any remaining basis.

SALT Cap — Increased to $40,000

The $10,000 cap on the State and Local Tax (SALT) deduction — one of the most controversial TCJA provisions — has been increased to $40,000 under the OBBBA, phasing in over several years.

Who benefits most:

• High-income taxpayers in high-tax states (California, New York, New Jersey, Illinois)
• Homeowners with significant property tax bills
• Dual-income households previously capped at $10,000 combined

Important caveat: The increased SALT deduction is only available to taxpayers who itemize deductions. With the standard deduction also increased under the OBBBA, the calculus of itemizing vs. taking the standard deduction must be recalculated for 2026.

Individual Tax Rates — TCJA Brackets Made Permanent

The TCJA's reduced individual income tax rates — including the 37% top rate (down from 39.6%) and the expanded 22% and 24% brackets — are made permanent under the OBBBA. This eliminates the planning uncertainty that existed when a sunset was possible.

2026 Top Marginal Rates:

Qualified Business Income (QBI) Deduction — Extended

The 20% deduction for pass-through business income under IRC §199A — available to sole proprietors, S-corps, partnerships, and LLCs — is extended under the OBBBA. This deduction can reduce the effective tax rate on qualified business income to as low as 29.6% for taxpayers in the 37% bracket.

Key limitations that remain:

• W-2 wage and qualified property limitations apply above the threshold
• Specified service trades or businesses (SSTBs) — including law, accounting, consulting, and financial services — face phase-outs above income thresholds
• The deduction cannot exceed 20% of taxable income minus net capital gains

Strategy: S-corp owners should revisit reasonable compensation levels in light of the extended QBI deduction. Paying yourself too much in W-2 wages reduces QBI; paying too little creates payroll tax exposure. The optimal split requires modeling.

Prior to the OBBBA, the TCJA's doubled estate and gift tax exemption was scheduled to sunset after 2025, dropping from approximately $13.6 million per person back to roughly $7 million (inflation-adjusted). The OBBBA addresses this — but the details matter.

Under the OBBBA, the estate and gift tax exemption is permanently increased and indexed for inflation. For 2026, the combined federal estate and gift tax exemption is approximately $15,000,000 per individual ($30,000,000 for married couples with proper planning).

The top estate tax rate remains 40% on amounts above the exemption.

The annual gift tax exclusion — the amount you can give to any individual without using your lifetime exemption — is $19,000 per recipient in 2026 (up from $18,000 in 2024, indexed for inflation).

For a married couple using gift-splitting, this means $38,000 per recipient per year with no gift tax return required and no exemption consumed.

Irrevocable Life Insurance Trusts (ILITs)

With the exemption now permanent at elevated levels, ILITs remain valuable for keeping life insurance proceeds out of the taxable estate while providing liquidity for estate taxes or family needs.

Spousal Lifetime Access Trusts (SLATs)

A SLAT allows one spouse to make a completed gift to an irrevocable trust for the benefit of the other spouse, using the lifetime exemption while removing assets from the taxable estate. The beneficiary spouse retains access to trust distributions.

Caution: The "reciprocal trust doctrine" can unwind SLATs if both spouses create substantially identical trusts for each other. Proper structuring with different trustees, different terms, and staggered timing is essential.

Grantor Retained Annuity Trusts (GRATs)

GRATs allow you to transfer appreciation out of your estate at minimal gift tax cost. You transfer assets to the trust, receive an annuity for a fixed term, and any growth above the IRS hurdle rate (the §7520 rate) passes to beneficiaries gift-tax-free.

In a higher interest rate environment, GRATs require stronger asset performance to succeed — but they remain a core tool for transferring appreciating assets like closely held business interests or real estate.

Business Succession Planning

For business owners, the elevated exemption creates a window to transfer business interests at current valuations. Valuation discounts for lack of control and lack of marketability — typically 20–40% for minority interests in closely held entities — can significantly reduce the taxable value of transferred interests.

The SECURE 2.0 Act of 2022 staggered its provisions across multiple years. Several significant rules are now fully in effect for 2026.

Beginning in 2025 and continuing in 2026, individuals aged 60, 61, 62, or 63 are eligible for a "super catch-up" contribution to employer-sponsored retirement plans (401(k), 403(b), SIMPLE IRA).

2026 Contribution Limits:

Strategy: If you are between 60 and 63, this is your highest-contribution window. Maximize it — particularly in a pre-tax 401(k) if you expect to be in a lower bracket in retirement, or in a Roth 401(k) if you expect rates to rise.

For employees earning more than $145,000 in the prior year (indexed for inflation), catch-up contributions to employer plans must be made to a Roth account (after-tax). This provision, delayed from its original 2024 effective date, is now in effect.

Impact: High earners lose the pre-tax benefit on catch-up contributions. However, Roth contributions grow tax-free and are not subject to required minimum distributions — a long-term planning advantage.

The RMD starting age is now 73 (increased from 72 under the original SECURE Act). For individuals who turned 73 in 2025 or later, RMDs must begin by April 1 of the following year.

Roth 401(k) RMDs Eliminated: Beginning in 2024 and continuing in 2026, Roth accounts in employer plans are no longer subject to RMDs during the owner's lifetime — aligning them with Roth IRAs. This is a significant planning change for those who prefer to let Roth assets compound.

The annual limit for Qualified Charitable Distributions from IRAs directly to charity has been increased to $108,000 in 2026 (indexed for inflation). QCDs count toward your RMD, reduce your adjusted gross income (unlike a standard charitable deduction), and can reduce Medicare premium surcharges (IRMAA).

Strategy for retirees: If you are charitably inclined and subject to RMDs, a QCD is almost always more tax-efficient than taking the distribution and then donating — particularly if you take the standard deduction and would not otherwise benefit from itemizing charitable contributions.

SECURE 2.0 significantly enhanced the tax credits available to small businesses that establish new retirement plans:

• Startup credit: Up to $5,000 per year for 3 years (100% of startup costs for employers with ≤50 employees)
• Employer contribution credit: An additional credit of up to $1,000 per employee for employer contributions in the first five years of a new plan
• Auto-enrollment credit: $500 per year for 3 years for plans that include automatic enrollment

Strategy for small business owners: If you do not have a retirement plan in place, 2026 is an exceptionally low-cost year to establish one. The credits can offset nearly the entire cost of setup and administration in the early years.

1. Review entity structure — Is your S-corp reasonable compensation optimized for the QBI deduction?
2. Accelerate equipment purchases — 100% bonus depreciation is back; place qualifying property in service before December 31
3. Establish or maximize a retirement plan — Solo 401(k), SEP-IRA, or defined benefit plan depending on income level
4. Recalculate SALT — With the cap at $40,000, itemizing may now be more advantageous than the standard deduction
5. Consider a cost segregation study — If you own commercial or residential rental property, 2026 is the optimal year

1. Commission a cost segregation study now — 100% bonus depreciation on reclassified assets is the highest-value play in 2026
2. Evaluate STR vs. LTR classification — See our STR vs. LTR analysis for how IRC §469 affects your loss deductibility
3. Review 1031 exchange pipeline — Identify replacement properties before year-end to defer gain recognition
4. Check depreciation recapture exposure — If you are considering a sale, model the §1245 and §1250 recapture against the current 25% unrecaptured §1250 rate

1. Maximize super catch-up contributions if you are between ages 60–63
2. Model Roth conversion opportunities — With rates permanent, the calculus is clearer; convert in lower-income years
3. Review estate plan — The $15M exemption is now permanent, but your documents may still reference outdated thresholds or strategies designed for a sunset that did not happen
4. Harvest capital losses — Offset capital gains before year-end; wash sale rules apply
5. Evaluate QCDs if you are subject to RMDs and charitably inclined — reduces AGI more efficiently than a standard deduction

Most of these strategies require action before December 31, 2026. Bonus depreciation requires property to be placed in service. Retirement plan contributions have funding deadlines. Gift tax annual exclusions reset on January 1. Estate planning documents take time to draft and execute properly.

The taxpayers who benefit most from a favorable tax environment are the ones who plan proactively — not the ones who call in April.
