NEW HAVEN, CT – Jose’s Tax Service – March 26, 2026

The tax deadline of April 15th is exactly twenty days away. For small business owners in New Haven, this period is often characterized by a frantic search for receipts and a deep-seated hope that the final bill isn't too high. However, hope is not a strategy. With the recent legislative changes introduced in the "One Big Beautiful Bill Act" of 2025, the landscape for small business deductions has shifted significantly for the 2026 filing season.

If you are a sole proprietor, a partner in a local firm, or an LLC owner in the Elm City, you have a limited window to implement specific strategies that can reduce your 2025 tax liability. At Jose’s Tax Service, we specialize in navigating these complex updates to ensure our clients keep more of their hard-earned revenue.

Here are seven critical last-minute tax moves you must consider before the April 15th deadline.

1. Maximize the Increased QBI Deduction!

The Qualified Business Income (QBI) deduction, also known as the Section 199A deduction, has undergone a significant expansion. Starting in 2026, pass-through business owners can now deduct 23% of their qualified business income, an increase from the previous 20% rate.

For a New Haven sole proprietor reporting $120,000 in qualified business income, this three-percent increase generates an additional $3,600 in deductions. This is a powerful tool for reducing taxable income without spending an extra dime on business expenses.

Actionable Step: Review your 2025 income statements immediately. Ensure your filing status and income thresholds allow for the full 23% deduction. If you are unsure how the phase-out limits apply to your specific New Haven business, contact us for a quick review.

2. Claim 100% Bonus Depreciation on 2025 Equipment!

Timing is everything when it comes to depreciation. Under current regulations, if you purchased qualifying business equipment after January 19, 2025, you are eligible to claim 100% first-year bonus depreciation.

This means you can fully deduct the cost of machinery, computers, office furniture, or qualifying vehicles in the year they were placed in service, rather than spreading the deduction over several years. This is a massive "front-loading" of tax benefits that can drastically lower your current tax bill.

Official Requirement: You must file IRS Form 4562, Depreciation and Amortization, with your tax return to document these claims. Failure to file this form correctly may lead to the IRS rejecting the accelerated deduction, forcing you into a multi-year depreciation schedule.

3. Utilize the Expanded Section 179 Deduction!

While bonus depreciation is powerful, Section 179 remains a cornerstone of small business tax planning. For the 2026 filing season, the Section 179 deduction limit has been increased to $2.5 million.

This provision allows you to deduct the full purchase price of qualifying equipment and software purchased or financed during the tax year. This includes heavy SUVs (over 6,000 lbs) used primarily for business. For a local contractor or delivery service in New Haven, this deduction can offset a substantial portion of the year's profits.

Note: Section 179 is generally limited to taxable business income, meaning you cannot use it to create a net loss for the year. However, any excess can often be carried forward. Review the tax-planning section of our blog for more details on asset expensing.

4. Optimize Your Home Office Deduction!

Many New Haven entrepreneurs operate from home offices. You have two choices for claiming this deduction, and choosing the wrong one could cost you money.

• The Simplified Method: You can claim $5 per square foot of your home used for business, up to 300 square feet. This results in a maximum deduction of $1,500. This method is fast and requires minimal record-keeping.
• The Actual Expense Method: This requires calculating the actual costs of your home (mortgage interest, insurance, utilities, repairs) based on the percentage of the home used for business.

With rising utility costs in Connecticut, the actual expense method often yields a higher deduction for New Haven residents. However, it requires meticulous documentation.

Instruction: Measure your workspace today. If the space is dedicated exclusively to business, calculate both methods to see which saves you more. You can find more tips on this at the small-business-learning-center.

5. Capture All Vehicle and Mileage Deductions!

If you use your personal vehicle for business: whether visiting clients in Westville or picking up supplies in Long Wharf: you must claim your mileage. For the 2025 tax year, the standard mileage rate is $0.70 per mile.

If you have not kept a consistent mileage log, you can still claim actual expenses. Gather all receipts for:

• Gasoline and oil
• Repairs and maintenance
• Tires and insurance
• Registration fees

Warning: The IRS frequently audits vehicle deductions. You must be able to prove the business purpose of your trips. If you lack a written log, start reconstruction now using your digital calendar and service records.

6. Adjust for Connecticut's SALT Deduction Changes!

Connecticut business owners have long been burdened by the $10,000 cap on State and Local Tax (SALT) deductions. However, following federal changes, this cap is largely expected to be removed or significantly altered for 2026.

This is particularly relevant for New Haven business owners who pay high property taxes and state income taxes. Review your 2025 state tax payments. You may be able to deduct a significantly higher portion of these taxes against your federal income than in previous years.

Pro-Tip: Check our news category frequently for updates on CT-specific tax legislation that could affect your final filing.

7. Deduct Professional Services and Operating Expenses!

Don't overlook the "small" things. All "ordinary and necessary" expenses for running your business are deductible. This includes:

• Professional Fees: Fees paid to Jose’s Tax Service for tax preparation and consultation are deductible business expenses.
• Marketing: Any advertising in local New Haven publications or digital ads.
• Software: Monthly subscriptions for accounting, CRM, or specialized trade software.
• Continuing Education: Classes or seminars taken to improve your skills in your current trade.

Gathering these smaller invoices can often add up to thousands of dollars in deductions that were previously hidden in your bank statements.

The Deadline is Approaching!
The IRS is strict regarding the April 15th deadline. While you can file an extension (Form 4868), an extension to file is not an extension to pay. Any taxes owed must still be paid by April 15, 2026, to avoid interest and penalties.
