The One Big Beautiful Bill Act (OBBBA) is one of the most sweeping tax reform proposals aimed at revitalizing the U.S. tax system for both entrepreneurs and everyday taxpayers. If you’re a startup founder or individual taxpayer navigating the evolving tax landscape, here’s what you need to know about how OBBBA could significantly impact your financial strategy.

OBBBA Benefits for Startups

Startups stand to gain significantly under OBBBA, especially through capital gains relief and business-friendly deductions.

1. QSBS Overhaul – Bigger Exemptions, Faster Payouts

The Qualified Small Business Stock (QSBS) exclusion is now tiered:

1. 50% exclusion after 3 years
2. 75% after 4 years
3. 100% after 5 years

The gain exclusion cap has increased to $15M per issuer, with strategies enabling even higher tax-free gains.

Why it matters: Early investors and founders can unlock capital gains tax savings sooner while enjoying larger exclusions than ever before.

Example:

Sarah, a founder of a biotech startup, holds QSBS shares issued in August 2025.

1. If she sells after 3 years, 50% of her $10M gain ($5M) is tax-free.
2. If she holds for 5 years, 100% of the gain ($10M) is excluded.
3. With the new $15M cap, she could potentially exclude an additional $5M compared to the old law.

2. Enhanced Startup Deductions

1. Startup expenses deductible in the first year have been raised to $30,000, cutting early tax liabilities.
2. 100% bonus depreciation and expanded Section 179 expensing allow immediate write-offs of equipment and capital expenditures.

Example:

A new SaaS company spends $25,000 on legal fees, branding, and initial software tools.

Under the old rules, only $5K was deductible.

Under OBBBA, the full $25K can be deducted in year one, lowering taxable income and freeing up cash.

3. Increased R&D Credits

1. The refundable R&D tax credit limit has risen to $750,000.
2. Streamlined filing means startups can access funds faster, crucial for cash flow.

Example:

A robotics startup spends $800K on R&D in 2025.

1. They qualify for the expanded refundable R&D credit of $750K, which can offset payroll taxes directly.
2. This reduces their monthly payroll tax burden and extends their runway.

OBBBA Tax Relief for Individuals:

OBBBA also introduces targeted tax breaks to support working Americans, families, and retirees.

1. Standard Deduction & Brackets

1. The enhanced standard deduction is now permanent.
2. The seven TCJA-era tax brackets remain, offering stability in planning.

Example:

John, a single filer earning $60K, claims the increased standard deduction.

1. His taxable income drops by roughly $15K, saving him over $2,000 compared to pre-OBBBA rates.

2. Special Deductions (2025–2028)

For a limited time, taxpayers benefit from:

1. No federal tax on tips (up to $25K) for workers earning below $150K.
2. Overtime deduction up to $12,500 ($25K for joint filers).
3. Vehicle loan interest deduction for U.S.-assembled EVs and qualified cars (up to $10K/year).

3. Boosts for Families and Seniors

1. Child Tax Credit raised to $2,200 per child, with $1,700 refundable.
2. Senior deduction of $6,000 ($12K joint) for taxpayers 65+, reducing taxable income significantly.
3. Trump Baby Bonus Account gives $1,000 for children born 2025–28, growing tax-deferred until age 18.

4. Estate & Gift Tax Opportunities

1. The estate tax exemption jumps to $15M per individual ($30M joint), creating powerful estate planning possibilities.

Example:

The Johnson family plans to pass down a $25M estate.

1. Under OBBBA, $30M is exempt for joint filers, meaning their heirs pay no estate tax.

The OBBBA is more than a tax cut, it’s a strategy tool. For startups, it accelerates capital formation and rewards innovation. For individuals, it delivers short-term relief and long-term planning opportunities.

With many provisions expiring after 2028, timing is everything. Work with a tax advisor now to ensure you maximize savings under this historic tax reform.
