What Are the Major Federal Tax Deductions for 2026?
Quick Answer: The 2026 tax year introduces four groundbreaking deductions: tips (up to $25,000), overtime income (up to $12,500), senior standard deduction boost ($6,000 additional), and a revolutionary increase in the SALT deduction to $40,000 through 2029.
The One Big Beautiful Bill Act (OBBBA), enacted July 4, 2025, fundamentally transforms federal tax deductions starting with the 2026 tax year. For New Hampshire residents, these changes represent extraordinary planning opportunities since they eliminate state income tax complications.
No Federal Tax on Tips and Overtime Income
Beginning January 1, 2026, service workers and employees earning tips can exclude up to $25,000 annually from federal taxable income through a direct deduction (not subject to itemization). This provision applies to married couples filing jointly or individuals in high-tip industries.
Similarly, the overtime income deduction allows workers to deduct up to $12,500 for single filers on earned overtime compensation. These deductions phase out at higher income levels but provide substantial relief for middle-income workers.
Planning consideration: If your household income includes service or overtime earnings, calculate your eligibility immediately. The phase-out thresholds begin at $75,000 modified adjusted gross income (MAGI) for individuals and $150,000 for married couples.
Enhanced Senior Standard Deduction
Taxpayers age 65 and older receive an additional standard deduction of $6,000 for 2026 (compared to previous years). For married couples where both spouses are 65 or older, this compounds to $12,000 additional deduction combined, meaning the total 2026 standard deduction reaches $43,500 for married filing jointly couples both over 65.
This deduction phases out for higher-income retirees making above $75,000 (single) or $150,000 (married filing jointly).
Pro Tip: New Hampshire retirees should immediately run tax projections comparing standard vs. itemized deductions. With the enhanced senior deduction and no state income tax burden, many will benefit significantly from claiming the full standard deduction in 2026.
| Filer Status | 2026 Standard Deduction | Age 65+ Additional | Total (Age 65+) |
|---|---|---|---|
| Single | $15,750 | $6,000 | $21,750 |
| Married Filing Jointly | $31,500 | $12,000 (both 65+) | $43,500 |
| Head of Household | $24,150 | $6,000 | $30,150 |
How Does the $40,000 SALT Deduction Help New Hampshire Earners?
Quick Answer: For 2026-2029, the state and local tax (SALT) deduction cap increased from $10,000 to $40,000, dramatically benefiting high-income NH residents who pay substantial property taxes and can now deduct these costs when itemizing.
One of the most impactful 2026 tax changes for New Hampshire high-earners is the expanded SALT deduction. This $40,000 cap applies through 2029 and includes property taxes, state income taxes (where applicable), and local taxes. New Hampshire residents gain a distinct advantage here.
Why New Hampshire Residents Benefit Disproportionately
Because New Hampshire imposes no state income tax, residents don’t “waste” SALT deduction capacity on income taxes. Instead, the full $40,000 capacity can absorb New Hampshire property taxes, which often exceed $4,000-$8,000 annually for middle-class homes.
Consider a high-net-worth NH resident earning $400,000 annually with $15,000 in combined property and local taxes. Under 2025 rules, only $10,000 was deductible. For 2026, the full $15,000 becomes deductible, creating $5,000 in additional deduction capacity worth roughly $1,850 in tax savings (at 37% marginal rate).
SALT Phase-Out Rules for 2026
The $40,000 SALT deduction includes a phase-out mechanism: taxpayers with modified adjusted gross income (MAGI) exceeding $500,000 begin losing deduction capacity. The cap reduces entirely to $10,000 for filers with MAGI above $600,000.
This means ultra-high-net-worth New Hampshire residents ($600,000+ income) revert to the $10,000 cap, while upper-middle-class professionals ($350,000-$500,000 range) can claim the full $40,000.
How Do New 2026 Self-Employment Tax Changes Impact You?
Quick Answer: For 2026, self-employed professionals pay 15.3% in combined self-employment tax (12.4% Social Security + 2.9% Medicare) on net business income up to the $184,500 Social Security wage base, then 2.9% Medicare-only tax on earnings above that threshold.
New Hampshire’s self-employed and 1099-contractor population faces critical 2026 planning decisions. While federal self-employment tax rates remain constant at 15.3%, new federal deductions (tips, overtime) and expanded tax strategy opportunities change how to optimize net income.
Quarterly estimated tax payments become essential in 2026. Self-employed professionals should calculate adjusted net income, apply the 92.35% net earnings multiplier, and divide by four quarters to determine quarterly payment amounts due April 15, June 15, September 15, and January 15.
Pro Tip: Self-employed contractors should use our Self-Employment Tax Calculator to determine 2026 quarterly payment obligations based on YTD net income. Underpayment penalties kick in if quarterly payments fall short by $1,000+ annually.
Maximizing Deductions to Reduce SE Tax Burden
Every dollar of business deduction reduces self-employment tax by approximately 15.3%. This means maximizing home office deductions, equipment depreciation, professional liability insurance, and contract labor costs becomes a tax-efficiency strategy.
For 2026, consider accelerating depreciation schedules for equipment purchased before year-end using Section 179 expensing rules. A $50,000 equipment purchase can generate $7,650 in immediate self-employment tax savings if properly structured.
What Tax Planning Strategies Should Business Owners Use?
Free Tax Write-Off FinderQuick Answer: Business owners should leverage the reinstated R&D expensing rules, maximize qualified business income (QBI) deductions at 20%, consider strategic entity structuring, and coordinate timing of distributions and salary payments to optimize 2026 federal tax liability.
New Hampshire business owners benefit enormously from the absence of state income tax when implementing strategic tax planning. This frees resources for federal optimization without state-level complications.
Research & Development (R&D) Expensing Changes
The 2026 tax year reintroduces immediate deductions for domestic research and development costs under OBBBA. Previously, businesses had to amortize R&D costs over 15 years. Now, qualifying businesses can immediately deduct domestic R&D expenses or elect to capitalize and amortize over 60 months.
This change particularly benefits technology companies, software developers, manufacturers, and professional service firms conducting innovation activities. A business with $100,000 in qualifying R&D costs could generate $37,000 in federal tax savings (at 37% marginal rate).
Qualified Business Income (QBI) Deduction Optimization
Business owners can deduct up to 20% of qualified business income under Section 199A. For 2026, this provision remains unchanged and available to S-Corps, LLCs, and sole proprietors. Effective entity structuring determines whether you qualify.
A business generating $200,000 in qualified business income can claim a $40,000 deduction annually, reducing taxable income to $160,000. Over 10 years, this strategy compounds to over $400,000 in cumulative deductions assuming consistent income.
| Business Owner Profile | Estimated 2026 Tax Savings Strategy | Estimated Impact |
|---|---|---|
| Service-Based Solo ($75K income) | QBI deduction + Home office maximize | $3,700 savings |
| Tech/Software ($250K income) | R&D expensing + QBI deduction | $22,200 savings |
| Manufacturing ($500K income) | Section 179 expensing + R&D | $54,600 savings |
Should You Open a 2026 Trump Account for Your Children?
Quick Answer: Yes—if you have newborns born 2025-2028, they qualify for a one-time $1,000 federal pilot contribution to a tax-advantaged Trump account beginning July 4, 2026. This gift grows tax-free until age 18.
Trump accounts represent a new long-term retirement savings vehicle for children under 18. The OBBBA established this mechanism, with IRS regulations finalized March 6, 2026. Each eligible newborn receives a one-time $1,000 federal contribution if parents elect by December 31 of the year the child turns 17.
Parents can add additional contributions (from after-tax dollars or employer/nonprofit contributions up to $5,000 annually). Investments must track U.S. equity index funds or ETFs. The account converts to traditional IRA treatment after the child reaches age 18.
For a child born in 2026 with parents who contribute $1,000 annually until age 18 (18 contributions), and assuming 7% annual investment growth, the account balance reaches approximately $42,000 by age 18—all tax-free growth.
Uncle Kam in Action: Real Tax Savings for New Hampshire Professionals
Client Profile: Sarah, a 52-year-old independent marketing consultant in Manchester, NH, earning $180,000 annually through her 1099 contracting business. Married filing jointly with spouse earning $85,000 W-2 income. Combined household income: $265,000.
2025 Tax Liability: Sarah paid $52,300 in combined federal income and self-employment taxes. Her SALT deduction was capped at $10,000 (property taxes $11,500), limiting her deduction capacity.
2026 Uncle Kam Strategy: Implemented four tax-optimization tactics: (1) Restructured Sarah’s 1099 business as an S-Corp to optimize salary vs. distribution split, reducing self-employment tax by $8,400 annually; (2) Maximized QBI deduction by documenting business income at $140,000 (after reasonable salary), generating $28,000 QBI deduction; (3) Expanded SALT deduction to $40,000 (from $10,000), capturing additional $9,500 in property tax deductions; (4) Accelerated equipment purchases for 2026, claiming $15,000 Section 179 expensing.
2026 Results: Sarah’s federal tax liability dropped to $38,100—a $14,200 annual savings. Investment in professional tax consulting ($2,500 fee) delivered a 5.6x return on investment. She’s now on track to deploy these savings into retirement planning and business growth.
This case illustrates why New Hampshire business owners benefit from comprehensive tax advisory services. The state’s absence of income tax means more federal optimization opportunities than neighboring states.

Frequently Asked Questions
Will New Hampshire Ever Implement a State Income Tax?
As of March 2026, New Hampshire remains one of only nine states with no income tax. While occasional proposals surface, constitutional amendments would be required, making broad implementation unlikely in the foreseeable future. NH residents should continue leveraging this advantage for federal optimization.
How Does the $40,000 SALT Deduction Phase-Out Work Exactly?
For 2026, the SALT deduction permits up to $40,000 in deductions for modified adjusted gross income (MAGI) up to $500,000. Between $500,000-$600,000 MAGI, the deduction phases out proportionally. Above $600,000 MAGI, the cap reverts to $10,000. This phase-out applies through 2029.
Can Self-Employed Professionals Deduct Home Office Expenses in 2026?
Yes. Self-employed professionals can claim home office deductions using either the simplified method ($5 per square foot, up to 300 sq ft = $1,500 max) or actual expense method. The 2026 home office deduction remains deductible on Schedule C, reducing self-employment tax liability.
What’s the Deadline for Opening a Trump Account for My 2026 Newborn?
Trump account elections must be filed using Form 4547 by December 31 of the year the eligible child turns 17. For children born in 2026, parents have until December 31, 2043 to make the election. However, contributions cannot be made before July 4, 2026.
Should I Convert to an S-Corp Before Year-End 2026?
S-Corp conversion timing is critical. If you convert during 2026, you must file tax returns under both structures, complicating compliance. Consider conversion for 2027 tax year (filing in 2028) to capture full-year benefits. Consult a tax specialist before converting.
Are IRA Contribution Limits Higher in 2026?
Yes. For 2026, individual retirement account (IRA) contribution limits increase to $7,500 (compared to $7,000 in 2025) for filers under age 50. Those age 50+ can contribute $8,500 ($7,500 + $1,000 catch-up). Contribution deadlines are typically April 15 following the tax year.
How Are Trump Accounts Taxed When the Child Reaches Age 18?
At age 18, Trump accounts convert to traditional IRA treatment. All earnings become taxable upon distribution. Distributions taken before age 59.5 are subject to 10% early withdrawal penalties unless an exception applies. The account structure changes from growth-phase (tax-free until 18) to distribution-phase (taxable distributions).
