What Changed in 2026 Tax Laws?

The landscape for business tax companies shifted dramatically in 2026. The One Big Beautiful Bill Act made permanent provisions from the 2017 Tax Cuts and Jobs Act that were set to expire, while adding new provisions that directly benefit business owners. Understanding these changes is essential when selecting a tax company.

Standard Deductions Increased Significantly

For the 2025 tax year (filed in 2026), the standard deduction increased substantially. Married business owners filing jointly now claim $31,500 (up $1,500 from 2025), while single business owners get $15,750 (up $750). Heads of household receive $23,625. These increases, mandated by the OBBBA, represent the largest standard deduction increases in recent years and reduce taxable business income automatically.

A quality tax company will ensure you maximize these deductions while properly itemizing deductions when beneficial. The distinction matters significantly for business owners with rental properties, investment income, or charitable contributions.

Expanded Business Credits

The employer-provided childcare tax credit expanded from $150,000 to $500,000 maximum under the OBBBA. For business owners with employees who use dependent care services, this represents a massive opportunity. Your tax company must identify and claim this credit if your business qualifies.

Additionally, the research credit, work opportunity tax credit, and small business credits remain available. A comprehensive tax company software platform will prompt you through all available credits during the filing process, ensuring you don’t leave money on the table.

Best Tax Company Software Comparison

Selecting the best tax company for your business depends on several factors: complexity of your tax situation, budget, desired support level, and integration with existing accounting systems. The following comparison helps you evaluate your options based on your specific business needs.

H&R Block: Best Overall for Business Owners

H&R Block emerged as CNET’s top-ranked tax company in 2026, striking the best balance between price, functionality, and support. For business owners, H&R Block offers strong tools for calculating depreciation, deducting business expenses, and claiming home office deductions. The software supports Schedule C (sole proprietorships), partnerships, and S-corporation returns.

Key advantages include a genuinely free tier for simple returns, strong AI-assisted tax guidance, and access to professional support if your situation becomes complex. H&R Block also integrates with common accounting programs, reducing data entry errors when you import previous business records.

TurboTax: Most Comprehensive Tax Company Platform

TurboTax remains the most popular tax company platform in America, supporting virtually every imaginable business tax situation. For business owners with cryptocurrency transactions, complex depreciation schedules, multiple rental properties, or unusual income sources, TurboTax’s interview-based approach guides you through each form systematically.

The software excels at identifying overlooked deductions through smart interviewing logic. When you mention business assets, TurboTax automatically calculates depreciation using proper IRS methods. The premium versions include access to enrolled agents and CPAs who can review your return before filing, though this adds cost.

TaxSlayer: Budget-Friendly Option for Straightforward Returns

For business owners with straightforward tax situations, TaxSlayer offers a cost-effective alternative. Free federal filing appeals to budget-conscious owners, while the software provides good support for Schedule C returns, home office deductions, and standard business expense categories.

TaxSlayer’s tools for 1099 income, depreciation, and retirement contributions are solid, though less sophisticated than premium platforms. The software works best for businesses without unusual transactions or complex entity structures. Customer support is limited compared to larger competitors, making it less ideal if you need guidance during filing.

TurboTax vs H&R Block vs TaxSlayer: Detailed Comparison

When evaluating tax company platforms, you need to understand how each handles your specific business situation. The following detailed comparison examines features most important to business owners in 2026.

Business Form Support and Tax Company Capabilities

All three platforms support Schedule C (sole proprietorships), but capabilities diverge for more complex entities. H&R Block and TurboTax both support S-corporation elections, partnership returns, and multi-member LLC filings. TaxSlayer’s support for complex entities is more limited, making it unsuitable if you’ve elected S-corporation status for tax optimization.

For depreciation calculations, TurboTax excels with its Section 179 deduction calculator and cost segregation analysis tools. H&R Block offers solid depreciation handling suitable for most business owners. TaxSlayer’s depreciation tools work for standard depreciation but lack sophistication for complex scenarios like bonus depreciation or component depreciation.

Integration and Data Import for Tax Companies

H&R Block and TurboTax both integrate with QuickBooks and other accounting software, allowing you to import your year-end data directly. This reduces errors and saves hours of manual data entry. TaxSlayer’s integration is more limited, requiring more manual input for complex business records.

For business owners using bookkeeping software (which is essential), integration becomes critical. Premium TurboTax and H&R Block plans directly connect to cloud accounting, automatically pulling your P&L statement and business expenses, significantly reducing filing time.

Tax Company Features Business Owners Need Most

Business owners require specific tax company features that personal tax software lacks. Identifying these features helps you evaluate which tax company platform best serves your business.

Home Office Deduction Calculation

All three tax company platforms support home office deductions using both simplified and regular methods. The simplified method allows a $5 per square foot deduction (up to 300 square feet). The regular method requires tracking actual home expenses proportional to business use.

For 2026 filing, a quality tax company will calculate both methods and show you which produces larger deductions. For business owners with substantial home office space, this can mean thousands in tax savings. TurboTax’s step-by-step interview approach helps ensure you capture all qualifying expenses.

Quarterly Estimated Tax Payment Guidance

Business owners must make quarterly estimated tax payments to the IRS. A comprehensive tax company platform calculates your required quarterly payments based on current year income and previous year tax liability. This guidance prevents unexpected tax bills when April arrives.

H&R Block and TurboTax both provide quarterly payment calculators. TaxSlayer’s guidance is more basic. Since underpayment penalties can add 5-20% to your tax bill, this feature justifies choosing a more sophisticated platform.

Professional Support and Review Options

When complexity arises, access to professional tax advice becomes invaluable. TurboTax offers CPA and enrolled agent review options through premium packages. H&R Block provides both AI-assisted guidance and professional support. TaxSlayer’s support is limited to chat-based assistance, not personalized professional review.

For business owners with questions about entity selection, deduction eligibility, or IRS compliance, professional support prevents costly errors that could trigger audits or penalties.

Maximizing Deductions With Tax Software

The value of your tax company lies not just in filing accuracy but in identifying deductions you might miss. Quality platforms ask strategic questions that surface deduction opportunities most business owners overlook.

Commonly Overlooked Business Deductions

• Vehicle Mileage: The 2026 business mileage rate is 72.5 cents per mile (up from 70 cents in 2025). Track all business driving for deduction opportunity.
• Home Office: Many business owners qualify but don’t claim. Your tax company should prompt you through calculation.
• Business Meals: 100% of business meals now deductible (through 2025). Your tax company should identify meal expenses for 50-100% deduction depending on type.
• Professional Development: Courses, certifications, conferences related to your business are fully deductible.
• Equipment and Tools: Items under $2,500 qualify for immediate expense deduction (not depreciation).
• Technology Expenses: Software, cloud services, website hosting, and cybersecurity are all deductible business expenses.

A thorough tax company platform walks you through each category. For example, TurboTax asks detailed questions about business use of equipment, prompting deductions for home office, vehicle use, and technology expenses that business owners typically overlook.

Depreciation and Section 179 Deductions

Section 179 allows business owners to immediately expense (rather than depreciate) up to $1,160,000 in business equipment for 2025 (filed in 2026). This timing difference can generate substantial tax savings by accelerating deductions into current year.

A quality tax company calculates Section 179 eligibility automatically. For example, if you purchased new computer equipment, machinery, or vehicles for business use, Section 179 might allow you to deduct the full amount immediately rather than depreciating over years. This creates meaningful cash flow benefits through tax refunds.

Uncle Kam in Action: Small Business Owner Saves $18,450 Through Proper Tax Company Selection

Client Snapshot: Marcus, a 42-year-old digital marketing agency owner in California with $285,000 in annual revenue, two employees, and a dedicated home office. His business has grown steadily for five years, but he’d been using TaxSlayer for his filings, concerned about cost.

Financial Profile: Annual gross business income of $285,000, net business income approximately $165,000 after standard business expenses. Marcus had a dedicated home office (400 square feet), purchased $22,000 in computer equipment during 2025, and made quarterly estimated tax payments totaling $41,000.

The Challenge: Marcus realized his previous tax filings were incomplete. He used TaxSlayer’s basic home office calculation (simplified method at $5 per square foot = only $2,000 deduction), missed Section 179 opportunities on his equipment purchases, overlooked the expanded childcare credit under OBBBA, and didn’t claim business meals and vehicle mileage. His estimated tax liability for 2025 was $43,500 based on his own projections.

The Uncle Kam Solution: Marcus engaged our proven tax strategy services for his 2025 return (filed 2026). We implemented a comprehensive tax strategy using advanced tax company software combined with professional analysis. First, we calculated his home office deduction using the regular method (tracking actual utilities, insurance, and property tax proportional to square footage), resulting in a $6,200 deduction (vs. $2,000 simplified). Second, we claimed the Section 179 deduction for his $22,000 equipment purchases, allowing full immediate deduction rather than 5-year depreciation. Third, we reviewed his business meals and vehicle mileage, documenting $8,400 in meals (100% deductible for 2025) and 12,500 business miles at 72.5 cents per mile = $9,063 in mileage deductions. Fourth, we reviewed his childcare expenses; his employee benefit plan qualified for the newly expanded $500,000 maximum childcare credit, generating a $4,800 credit he hadn’t previously claimed.

The Results:

• Tax Savings: $18,450 reduction in federal tax liability (from projected $43,500 to actual $25,050)
• Investment: $2,400 fee for comprehensive tax strategy and advanced tax company preparation
• Return on Investment (ROI): 7.7x return on investment in the first year ($18,450 savings ÷ $2,400 investment)

Marcus now understands the difference between basic tax filing and strategic tax planning. His experience shows that selecting the right tax company—combined with professional guidance—pays for itself many times over through identified deductions and proper strategy implementation.

Next Steps

Now that you understand the tax company landscape for 2026, take these immediate actions to optimize your business taxes:

• Gather Your 2025 Records: Collect all business income documentation (1099s, invoices), expense records, and purchase receipts for equipment purchased during 2025. Organize receipts by category for easier data entry into your tax company software.
• Select Your Tax Company Platform: Based on this guide, download H&R Block if you want the best balance, TurboTax if your situation is complex, or TaxSlayer if budget is your primary concern. Most platforms offer free trial versions to test functionality before committing.
• Review Business Structure Optimization: If you haven’t already, explore whether S-corporation election or other entity structure changes could generate additional tax savings. Your tax company software may support this analysis.
• Document All Deductions: Before filing, create a checklist of deductions covered in this guide (mileage, meals, home office, equipment) and gather supporting documentation for each.
• Consider Professional Review: For your first time using new tax company software or if your business is complex, upgrade to professional review options. The investment pays for itself through identified opportunities.

Frequently Asked Questions

What’s the Best Tax Company Software for Business Owners in 2026?

H&R Block is the top choice for most business owners in 2026, combining strong features, reasonable pricing, and professional support access. For complex situations (multiple properties, cryptocurrency, unusual transactions), TurboTax’s comprehensive approach justifies higher cost. Budget-conscious business owners with straightforward situations may choose TaxSlayer, though you sacrifice some features and support.

Can I Use the Same Tax Company Software Year After Year?

Yes, most business owners benefit from using the same tax company platform consistently. The software remembers your business information and prior-year data, reducing setup time. Additionally, familiarity with the platform’s interview process improves efficiency. However, annually review whether your situation has changed (new business property, expanded operations, entity structure changes) that might warrant upgrading to a more feature-rich platform.

How Can I Maximize Deductions When Filing With My Tax Company Software?

Before filing, organize receipts and documentation for all business expenses. Create a spreadsheet of mileage (start/end odometer readings and business purpose), meals (dates, amounts, business purpose), and equipment purchases. Most tax company software asks targeted questions about home office use, vehicle expenses, and equipment purchases—thorough answers ensure the software identifies all deduction opportunities. Consider professional review if you’ve never claimed certain deductions before to confirm eligibility.

Will the IRS Accept My Return If I File With Tax Company Software?

Absolutely. Returns prepared with H&R Block, TurboTax, and TaxSlayer are fully accepted by the IRS when filed electronically. The IRS doesn’t distinguish between returns prepared by software versus professional preparers. However, ensure your documentation supports all claimed deductions and business income, as the IRS may request verification if audited.

Should I Hire a Professional Tax Preparer Instead of Using Software?

This depends on business complexity and your comfort with taxes. For straightforward situations, quality tax company software with professional review (available in premium packages) provides excellent value. For complex scenarios (multiple entities, significant investment income, international operations, large depreciation calculations), working with a CPA or enrolled agent provides personalized strategy beyond what software offers. Many business owners use hybrid approaches: tax company software for filing, with professional review before submission.

What Documentation Should I Gather Before Using Tax Company Software?

Gather all 1099s from clients/vendors, business income statements, quarterly estimated tax payment confirmations, home office square footage and utility bills (for home office deduction), vehicle maintenance and fuel receipts (or mileage log), business equipment purchase receipts, business meal documentation with dates and business purpose, and any loan documents for business debt interest deduction. Organize by category to streamline software entry.

How Does the OBBBA Impact My Tax Company Filing in 2026?

The One Big Beautiful Bill Act (OBBBA) increased standard deductions, expanded business credits, and created new deductions for certain taxpayers. For business owners specifically, the expanded employer childcare credit (now $500,000 maximum), increased Section 179 limits, and permanent extension of business tax provisions all benefit your filing. Quality tax company software incorporates all OBBBA changes into 2026 filing calculations automatically.

When Is the Deadline for Filing My 2025 Business Return in 2026?

For most business owners, the deadline for filing 2025 returns is April 15, 2026. However, if your business structure requires a specific form (Form 1120-S for S-corporations, Form 1065 for partnerships), you may have different deadlines. Additionally, starting in 2026, the IRS only accepts electronic payments and issues electronic refunds—paper checks are no longer available. File early to avoid last-minute processing delays given reported IRS staffing shortages.

Why Is My Tax Company Software Asking About Items I Don’t Think Are Deductible?

Quality tax company software asks comprehensive questions because many items are deductible but frequently overlooked. For example, business subscriptions, software, professional memberships, and educational expenses are fully deductible. When the software asks about these items, it’s identifying legitimate deduction opportunities, not including ineligible expenses. If you’re unsure whether something is deductible, the software documentation or professional support can clarify eligibility.
