Small Business Tax Tips for 2026
Running a small business comes with important tax responsibilities. Understanding your federal tax obligations can help you stay compliant, maximize deductions, and avoid costly penalties. Whether you’re a sole proprietor, independent contractor, or employer, here’s what you should know for the 2026 tax year.
Know Which Federal Taxes Apply
Most small businesses are responsible for one or more of these federal taxes:
- Income Tax – Most businesses must report annual business income. Partnerships generally file an information return, while profits pass through to the owners.
- Self-Employment Tax – Sole proprietors and independent contractors generally pay self-employment tax if net earnings are $400 or more.
- Employment Taxes – Businesses with employees must generally withhold federal income tax, Social Security, and Medicare taxes, and pay federal unemployment (FUTA) tax.
- Excise Taxes – Certain industries, products, services, and activities may also be subject to federal excise taxes.
Important 2026 Tax Updates
Several IRS updates may affect small business owners in 2026:
- Business mileage rate: 72.5 cents per mile.
- Social Security wage base for self-employment tax: $184,500.
- 1099 reporting threshold: Increased to $2,000 for certain reportable payments made after 2025.
- Qualified Business Income (QBI) deduction: Made permanent with updated income thresholds.
- Excess Business Loss limitation: Permanently extended, with Form 461 required when applicable.
Keep Accurate Business Records
Good recordkeeping is one of the best ways to reduce errors and maximize deductions.
Maintain documentation for:
- Business income
- Receipts and expenses
- Mileage logs
- Payroll records
- Contractor payments
- Equipment and asset purchases
- Estimated tax payments
It’s also a good practice to keep separate business bank accounts and credit cards to simplify bookkeeping and support your deductions.
Understand Business Deductions
Ordinary and necessary business expenses are generally deductible. Common deductions include:
- Office expenses
- Business travel
- Rent for business property
- Employee wages
- Professional services
- Business insurance
Assets expected to last longer than one year generally must be depreciated, although Section 179 and bonus depreciation may allow faster cost recovery in qualifying situations.
Don’t Miss Estimated Tax Payments
Sole proprietors, partners, and many S corporation shareholders generally must make quarterly estimated tax payments if they expect to owe at least $1,000 after withholding and credits.
Typical due dates are:
- April 15
- June 15
- September 15
- January 15 of the following year
The IRS encourages electronic payments through Direct Pay, EFTPS, debit or credit card, or electronic funds withdrawal.
Payroll Compliance Matters
If your business has employees, payroll compliance should be a top priority. This includes:
- Obtaining employee tax information
- Proper worker classification
- Withholding and depositing payroll taxes
- Filing employment tax returns
- Issuing Forms W-2 on time
Incorrectly classifying employees as independent contractors can result in significant payroll tax liabilities and penalties.
