2026 Tax Changes for Business Owners: What You Need to Know Before Tax Season

Tax rules in the United States are constantly evolving, and 2026 brings several important changes that business owners should understand before preparing their next tax return.

The One Big Beautiful Bill Act (OBBBA), enacted in 2025, changed or extended several federal tax provisions that affect businesses, business owners, independent contractors, and investors. In addition, the IRS has released new inflation-adjusted amounts and guidance for the 2026 tax year.

For business owners, the key is not simply knowing that the rules changed. It's understanding how those changes may affect deductions, depreciation, reporting, estimated taxes, and overall tax planning.

In this guide, we'll cover the most important 2026 tax changes for business owners and what you should review before tax season.

What Is Changing for Business Owners in 2026?

Some of the most relevant changes include:

• Changes to depreciation rules;

• Updates affecting the Qualified Business Income (QBI) deduction;

• Changes to business information reporting thresholds;

• Updated mileage rates;

• Permanent treatment of excess business loss limitations;

• Inflation adjustments affecting tax brackets and other tax provisions;

• New rules and guidance resulting from the OBBBA.

  
  

Not every change applies to every business. Your company's structure, income, expenses, industry, and tax classification all matter.

1. 100% Bonus Depreciation Is Back

One of the most significant changes for businesses is the return of 100% additional first-year depreciation for qualifying property.

Under the OBBBA, eligible depreciable property acquired after January 19, 2025 may qualify for a permanent 100% additional first-year depreciation deduction, subject to the applicable rules. The IRS issued guidance on this provision in 2026.

This can be particularly relevant for businesses investing in:

• Equipment;

• Machinery;

• Computers;

• Certain vehicles;

• Business technology;

• Other qualifying depreciable property.

  
  

Why does this matter?

Instead of recovering the cost of qualifying assets over several years, a business may be able to deduct the full eligible amount in the year the property is placed in service.

This can create significant tax-planning opportunities for businesses making substantial investments.

However, not every purchase automatically qualifies, so the asset, acquisition date, and business use must be evaluated.

2. QBI Deduction Continues to Be Important

The Qualified Business Income (QBI) deduction under Section 199A remains an important tax planning tool for many pass-through business owners.

This deduction can potentially allow eligible owners of businesses such as:

• LLCs;

• Sole proprietorships;

• Partnerships;

• S Corporations;

  
  

to deduct up to 20% of qualified business income, subject to the applicable rules and limitations.

The OBBBA also modified certain QBI rules for future tax years, including making the deduction permanent and changing some phase-in and eligibility provisions.

Because QBI calculations can become complicated at higher income levels and for certain specified service businesses, proper tax planning is important.

3. The Business Reporting Threshold Increased

Another important change concerns information reporting for certain payments made in the course of a trade or business.

For payments made after December 31, 2025, the reporting threshold under Section 6041 increased from $600 to $2,000.

That means certain payments to vendors or service providers may not require information reporting until the $2,000 threshold is reached, subject to the applicable rules.

The threshold is scheduled to be indexed for inflation for calendar years after 2026.

Important:

This change does not mean businesses can stop keeping records of payments.

You should continue maintaining accurate:

• Vendor records;

• Invoices;

• Receipts;

• Contracts;

• Payment records;

• Bookkeeping documentation.

  
  

Good bookkeeping remains essential even when an information-reporting threshold changes.

4. The 2026 Business Mileage Rate Increased

If you use a vehicle for business purposes, the IRS standard mileage rate is an important number to know.

For 2026, the standard business mileage rate is 72.5 cents per mile.

This may be relevant to business owners and self-employed individuals who use their personal vehicles for qualifying business activities.

Examples can include:

• Visiting clients;

• Traveling between business locations;

• Attending business meetings;

• Traveling to qualifying business events.

  
  

It's important to maintain adequate mileage records, including the date, destination, business purpose, and miles driven.

5. Excess Business Loss Limitations Are Now Permanent

The OBBBA also made the excess business loss limitation permanent.

This rule can limit the amount of business losses that certain noncorporate taxpayers can use to offset other income.

The applicable threshold is adjusted for inflation for tax years beginning after 2025.

This can be particularly important for entrepreneurs who experience substantial business losses, especially when they have significant income from other sources.

A large business loss does not necessarily mean that the entire amount can immediately reduce your taxable income.

6. 2026 Tax Brackets and Standard Deduction Amounts Changed

Although these are individual tax provisions, they can be extremely important for business owners because many LLC owners and other pass-through business owners report business income on their personal tax returns.

For tax year 2026, the standard deduction is:

• $16,100 for single filers;

• $32,200 for married couples filing jointly;

• $24,150 for heads of household.

  
  

The federal individual tax rates remain:

10%, 12%, 22%, 24%, 32%, 35%, and 37%. 

For 2026, the top 37% rate begins above:

• $640,600 for single taxpayers;

• $768,700 for married couples filing jointly.

  
  

These numbers matter when planning owner compensation, distributions, estimated taxes, and other strategies.

7. Self-Employment Taxes Also Matter

If you operate your business as a sole proprietor, independent contractor, or another structure subject to self-employment tax, the Social Security portion of self-employment tax has a wage base limit.

For 2026, the maximum amount of net earnings subject to the Social Security portion of self-employment tax is $184,500.

This can be particularly relevant when planning income, estimated payments, and business structure.

8. Tax Planning Should Start Before Tax Season

One of the biggest mistakes business owners make is waiting until tax season to think about taxes.

By the time you're preparing your Tax Return, many planning opportunities for the previous year may already be gone.

Instead, consider reviewing your business throughout the year.

Some areas to analyze include:

• Business expenses;

• Equipment purchases;

• Depreciation;

• Payroll;

• Owner compensation;

• Estimated tax payments;

• QBI eligibility;

• Business structure;

• Retirement contributions;

• Vehicle use;

• Cash flow.

  
  

Tax planning is proactive. Tax preparation is reactive.

The best results often come from doing both.

9. Your Business Structure Still Matters

The tax impact of your business can vary significantly depending on how it is structured.

For example, an:

• LLC;

• S Corporation;

• C Corporation;

• Sole Proprietorship;

• Partnership

  
  

may have very different tax treatment.

For this reason, business owners should periodically evaluate whether their current structure continues to make sense as their business grows.

However, changing your tax election or entity structure should never be based solely on the idea of “paying less tax.”

You also need to consider payroll, compliance, administrative costs, state taxes, reasonable compensation requirements, and the overall economics of the business.

10. Bookkeeping Is More Important Than Ever

With changing tax rules, accurate bookkeeping becomes even more important.

Your accounting records should allow you to clearly identify:

• Revenue;

• Business expenses;

• Payroll;

• Contractor payments;

• Equipment purchases;

• Vehicle expenses;

• Owner distributions;

• Loans;

• Business assets.

  
  

Good Bookkeeping provides the foundation for accurate Tax Returns and better tax planning.

It also makes it easier to identify legitimate deductions and prepare the documentation needed to support them.

What Should Business Owners Do Before Tax Season?

Before your Tax Return is prepared, consider reviewing the following checklist:

✅ Reconcile all business bank accounts;

✅ Review your income and expenses;

✅ Organize receipts and invoices;

✅ Review contractor payments;

✅ Verify Payroll records;

✅ Review equipment and asset purchases;

✅ Calculate business mileage;

✅ Check estimated tax payments;

✅ Review your business structure;

✅ Evaluate available deductions and tax strategies;

✅ Make sure required federal and state filings are up to date.

The earlier you organize this information, the easier it becomes to identify potential tax planning opportunities.

What Are the Most Common Mistakes Business Owners Make?

Some of the biggest mistakes include:

❌ Waiting until tax season to start planning;

❌ Mixing personal and business expenses;

❌ Failing to document business expenses;

❌ Ignoring estimated tax payments;

❌ Missing Annual Report or other compliance deadlines;

❌ Assuming every expense is deductible;

❌ Classifying workers incorrectly;

❌ Making large purchases without considering the tax treatment;

❌ Choosing a business structure without proper tax analysis.

Tax mistakes can become expensive very quickly.
