The One Big Beautiful Bill Act was signed in July 2025, and most of what it changed for small business owners is retroactive to January 1, 2025, so it lands on the return filed in 2026. The standard deduction for tax year 2025 rose to $15,750 for single filers, $31,500 for married filing jointly, and $23,625 for head of household, above the $15,000 / $30,000 / $22,500 the IRS had previously announced, and it is now permanent. The Section 199A qualified business income deduction, which had been scheduled to expire after 2025, is permanent at 20%, with wider phase-in ranges for specified service businesses and a minimum deduction for active business income. Bonus depreciation returned to 100% and is permanent for qualifying property placed in service after January 19, 2025, replacing the 40% step-down that applied under prior law. Section 179 expensing rose to a $2.5 million limit with the phaseout beginning at $4 million of property placed in service, effective for property placed in service after December 31, 2024. Section 179 cannot create a net operating loss while bonus depreciation can, so the choice between them matters in a heavy-purchase, light-income year. The business interest limitation reverts to an EBITDA basis from 2025, letting more interest through. Two new deductions are temporary and run for tax years 2025 through 2028: up to $25,000 of qualified tips, and up to $12,500 of qualified overtime ($25,000 for joint filers), both phasing out above $150,000 of modified adjusted gross income ($300,000 joint), with the self-employed tips deduction capped at net income from the business where the tips were earned. Neither exempts the income from payroll tax. The Form 1099-NEC and 1099-MISC filing threshold rose from $600 to $2,000, but only for payments made after December 31, 2025, so 1099s filed in early 2026 for 2025 payments still use the $600 threshold. The Form 1099-K threshold is permanently restored to $20,000 and 200 transactions. A higher reporting threshold does not make income tax-free: self-employment tax still applies once net earnings reach $400. Because Florida has no state income tax, every one of these changes is a federal-only effect.
