What Changed for Business Owners in 2026?

The 2026 tax year marks a transformative period for business owners. The One Big Beautiful Bill Act (OBBBA), enacted in July 2025, made permanent most provisions of the 2017 Tax Cuts and Jobs Act, ensuring tax savings continue through 2026 and beyond. The IRS also implemented significant inflation adjustments that benefit all filers. For business owners specifically, these changes mean larger deductions, new opportunity zones, and strategic planning advantages.

The standard deduction for married business owners filing jointly rose to $32,200 in 2026, up $700 from 2025. Single business owners now benefit from a $16,100 standard deduction, an increase of $350. These base numbers matter because they determine whether itemizing or taking the standard deduction makes sense for your business structure. Additionally, the Child Tax Credit increased to $2,200 per qualifying child—a $200 boost that affects many small business owners with families.

New Deductions Available in 2026

For the first time, business owners who receive tips can deduct up to $25,000 annually in tip income. Similarly, workers claiming overtime or holiday premium pay can deduct up to $12,500 (single) or $25,000 (joint) from their taxable income. While these provisions apply primarily to W-2 workers, contract workers and sole proprietors should verify whether their income structure qualifies for these benefits.

One critical addition is the car loan interest deduction for U.S.-manufactured vehicles. Business owners financing new American-made vehicles can deduct up to $10,000 in annual loan interest—a provision available through 2028. This deduction applies whether you purchase for business or personal use, provided the vehicle’s final assembly occurred in the United States.

Updated 401(k) and Retirement Limits

Self-employed business owners using Solo 401(k) plans benefit from increased contribution limits in 2026. The annual deferral limit rose to $24,500 (up from $23,500), and catch-up contributions for those 50+ increased to $8,000. Solo 401(k) owners can contribute both as employee and employer, potentially sheltering $69,000+ annually from federal income tax (depending on self-employment income).

Traditional and SEP-IRA limits also increased. IRA contribution limits for 2026 are $7,500 (up from $7,000), with catch-up contributions of $1,000 for those 50 and older, bringing the total to $8,500. These changes directly impact your business owner tax strategy—the more you defer to retirement accounts, the lower your current taxable income.

Best Overall for Complex Business Returns: TurboTax

TurboTax dominates the market for complex business returns because it handles real-world complications most other platforms struggle with. If your business involves rental property depreciation, equipment write-offs, vehicle expense calculations, or multiple 1099 income sources, TurboTax provides the tools necessary to maximize deductions and maintain IRS compliance.

The platform supports Forms 1120 (C Corporation), 1120-S (S Corporation), 1065 (Partnership), and Schedule C (Sole Proprietor). This flexibility matters because your business structure determines tax filing requirements and deduction availability. TurboTax’s built-in guidance explains form dependencies and ensures you’re reporting correctly for your entity type.

Depreciation and Asset Tracking

For business owners tracking Section 179 deductions and depreciation schedules, TurboTax’s asset management module simplifies what would otherwise be manual form completion. The software guides you through capital asset purchases, calculates depreciation across multiple years, and generates Form 4562 (Depreciation and Amortization) automatically. This feature alone saves hours of work and reduces audit risk by ensuring consistent depreciation methodology.

Business owners can track vehicles separately from other equipment, apply bonus depreciation rules correctly, and maintain detailed records for audit support. TurboTax integrates this information into your tax return seamlessly.

Pricing and Support Options

TurboTax Plan	Price (2026)	Best For
Self-Employed (Federal)	$179.99+	Sole proprietors, independent contractors
Self-Employed with Live Expert Review	$339.99+	Complex returns with professional review
Business (for S Corp/Partnership)	$599.99+	S Corps, partnerships, multiple entities

TurboTax’s pricing reflects its feature depth. While entry-level plans start at $179.99, business owners with complex needs typically upgrade to the “with Professional Review” option ($339.99+), which includes consultation with a tax professional who can answer questions and review your return before filing.

Best for Self-Employed and Gig Workers: TaxSlayer

TaxSlayer targets business owners who want professional-grade tools without enterprise pricing. For solo entrepreneurs and gig workers, TaxSlayer provides exceptional value through strong 1099 import capabilities, guidance on common business deductions, and military discounts that eliminate federal filing costs entirely for active duty members.

The platform’s “Self-Employed” tier offers dedicated support for sole proprietors. You can upload 1099-NEC documents directly or manually enter income. The software then guides you through Schedule C completion, calculating net profit and transferring that figure to your personal return automatically.

Import Tools and Data Integration

TaxSlayer excels at simplifying data entry through import functionality. You can upload PDF copies of 1099-NECs from multiple clients, and the software extracts income automatically. This feature particularly appeals to freelancers managing multiple income sources—a common scenario for contractors working across five or more platforms.

The platform also guides you through common business deductions: home office expense calculations using the simplified or detailed method, vehicle expense tracking with mileage documentation, and depreciation for equipment purchases. While TaxSlayer doesn’t handle complex multi-year depreciation schedules as elegantly as TurboTax, it covers standard business owner deductions thoroughly.

Military Discount and Affordability

TaxSlayer’s standout feature for military members is free federal filing regardless of return complexity. Active duty service members pay zero for federal returns while their spouses and dependents receive discounted state filing. For military business owners, this advantage is substantial—professional tax software at zero federal cost.

For non-military self-employed individuals, TaxSlayer’s “Self-Employed” plan costs approximately $89.99-$109.99, significantly less than TurboTax’s comparable offering. This makes TaxSlayer attractive for business owners who don’t need enterprise-level feature support.

Best Tools for Freelancers and 1099 Contractors: H&R Block

H&R Block’s platform was engineered specifically for the gig economy. Freelancers working on Upwork, Fiverr, Toptal, and similar platforms face unique challenges: multiple 1099s from various clients, inconsistent payment timing, and complex deduction documentation. H&R Block’s “Self-Employed” package addresses these scenarios directly.

The software connects directly to your bank account and major financial institutions, allowing automatic expense categorization. As you upload receipts, the platform learns your spending patterns and suggests appropriate business expense categories. This automation saves significant time compared to manual expense entry, particularly for contractors managing dozens of monthly transactions.

1099 Import and Multiple Income Sources

H&R Block accepts direct imports of 1099-NECs from client platforms. If your clients issue 1099s through ADP, Guidepoint, or similar payroll providers, H&R Block can retrieve these documents electronically. The platform handles multiple 1099s seamlessly, consolidating income across sources and calculating self-employment tax automatically.

For business owners struggling with self-employment tax calculations, H&R Block’s automation is particularly valuable. The software calculates estimated quarterly payments based on your year-to-date income and provides payment deadline reminders—critical for freelancers who might otherwise miss IRS payment schedule dates.

Pricing and Customer Support

H&R Block’s “Self-Employed” package costs approximately $149.99-$199.99 for federal filing. The platform includes access to tax professionals during business hours for questions about your specific situation. While not as robust as TurboTax’s professional review option, this support level is sufficient for most freelancers with straightforward business structures.

H&R Block also offers an optional “Audit Support and Defense” add-on, providing representation if the IRS questions your return. For business owners concerned about audit risk—particularly those with aggressive deduction claims—this add-on provides peace of mind.

Best for Expert Support and Guidance: TaxAct

For business owners who want software simplicity combined with on-demand expert access, TaxAct bridges the gap between DIY filing and full-service accounting. The platform’s “Xpert Assist” feature connects you with a tax professional available to answer questions in real-time—critical when you’re unsure about deduction eligibility or business structure tax implications.

TaxAct’s interface is straightforward and walks you through return sections logically. The software supports sole proprietorships, S Corps, partnerships, and C Corps, though the feature set for more complex business structures is less robust than TurboTax’s offering.

Xpert Assist and Professional Consultation

The Xpert Assist feature is TaxAct’s differentiator. Rather than completing your entire return independently, you can chat with a tax professional who provides guidance on specific questions. This approach works well for business owners confident in their understanding but needing validation on particular deduction claims or entity election decisions.

Unlike TurboTax’s professional review option, Xpert Assist focuses on real-time consultation rather than return review. You maintain control of your filing while benefiting from expert input when needed. For budget-conscious business owners, this offers professional guidance at a fraction of full-service CPA costs.

Limitations for Complex Returns

TaxAct struggles with some advanced business scenarios. The platform doesn’t accept 1099-NEC uploads, requiring manual income entry. Multi-year depreciation schedules are less intuitive than TurboTax. If your business structure involves partnership distributions, S Corp reasonable compensation calculations, or complex entity elections, TurboTax or professional CPA services provide better support.

TaxAct’s best use case is the straightforward self-employed business owner who wants software guidance plus occasional expert consultation—not the owner with multi-entity structures or complex depreciation needs.

Uncle Kam in Action: Freelance Consultant Unlocks $8,400 in Savings Using Strategic Tax Preparation

Client Snapshot: Jessica, a freelance marketing consultant, operates as a sole proprietor generating $185,000 in annual 1099 income across five client platforms.

Financial Profile: Married filing jointly, one qualifying child, home office in Denver, combined household income of $285,000 from Jessica’s consulting and spouse’s W-2 employment.

The Challenge: Jessica was using a basic tax software that handled her 1099 income but provided no guidance on business deductions specific to consultants. She manually tracked mileage but wasn’t claiming home office expenses. Additionally, she wasn’t aware of the new 2026 car loan interest deduction for her recently financed vehicle purchase.

The Uncle Kam Solution: We recommended H&R Block’s Self-Employed package for its superior 1099-NEC import capabilities and automatic expense categorization. The software imported all five 1099-NECs directly, consolidated income, and guided Jessica through Schedule C completion. Critically, the platform identified qualifying home office expenses ($4,200 annually using the simplified method), calculated vehicle mileage deductions properly, and documented her new $10,000 car loan interest deduction for the 2026 tax year.

The Results:

• Tax Savings: $8,400 in additional tax savings from previously unclaimed deductions
• Investment: $199.99 for H&R Block Self-Employed package
• Return on Investment (ROI): 4,200% first-year ROI—the software paid for itself more than 42 times over

This is just one example of how choosing the right tax preparation software can unlock substantial tax savings for freelancers and business owners. Jessica’s case demonstrates the importance of software that understands self-employed deduction patterns and provides guidance beyond basic income reporting.

Next Steps

• Assess your business structure: Determine whether you operate as a sole proprietor, LLC, S Corp, or partnership—this drives which software platform fits best.
• Document 2026 deductions: Start tracking home office expenses, vehicle mileage, and equipment purchases immediately to maximize deductions when filing.
• Gather income documentation: Collect all 1099-NECs, business invoices, and income statements before choosing your tax preparation platform.
• Consider professional tax advisory services if your business complexity exceeds basic self-employed filing.
• Set up retirement plan contributions: Maximize Solo 401(k) or SEP-IRA contributions to reduce 2026 taxable income.

Frequently Asked Questions

Can I use free tax software if I’m self-employed?

Some free options exist for basic self-employment scenarios, but they’re limited. FreeTaxUSA offers free federal filing for simple business returns, but lacks sophisticated import tools and business guidance features. If you have multiple 1099 sources, business equipment depreciation, or home office deductions, paid software like TaxSlayer ($89.99) or H&R Block ($149.99) provides significantly better support. The small additional investment typically pays for itself through better deduction guidance.

What’s the difference between self-employment tax and income tax?

Self-employment tax (Social Security and Medicare) applies to net business income above $400 annually. Federal income tax applies based on your total taxable income after deductions. For 2026, the self-employment tax rate is 15.3% on approximately 92.35% of your net self-employment income. Quality tax software calculates both automatically and ensures you don’t under-withhold on quarterly estimated payments.

Which tax software handles S Corp and partnership returns best?

TurboTax is the clear leader for S Corp (Form 1120-S) and partnership (Form 1065) returns. The software handles reasonable salary calculations for S Corps, tracks distributions, calculates self-employment tax consequences correctly, and manages partnership K-1 reporting. H&R Block and TaxSlayer offer limited support for these entity types. For S Corp owners, TurboTax’s $599.99+ Business tier is worth the investment.

How do I claim the new 2026 deductions (tips, overtime, car interest)?

These new deductions are claimed on Schedule 1-A (Additional Deductions), which all major tax software supports for 2026. The software guides you through eligibility and calculates deduction amounts. The car loan interest deduction applies to U.S.-manufactured vehicles financed in 2026. TurboTax, H&R Block, and TaxSlayer all provide clear guidance on these new provisions.

Should I upgrade to professional review or expert support options?

Professional review is worthwhile if your return involves unusual situations (business sale, significant investment losses, complex depreciation). Xpert Assist (TaxAct) works well for business owners wanting consultation but maintaining filing control. For most straightforward 1099 contractors, standard software provides adequate guidance without upgrade costs.

What happens if I’ve been using outdated tax software?

Switching to current software isn’t complicated. Download your prior-year return from your old software and import it into the new platform. Most major software accepts prior-year data transfer. The 2026 tax year is an ideal time to switch to software better suited to your evolving business complexity.
