Morning: Small Business Tax Tips (New Haven): Vehicle Mileage Deductions : Track 2026 Trips Correctly With the New IRS Rates

New Haven, Connecticut : Jose's Tax Service : September 4, 2026

The Internal Revenue Service (IRS) has changed the 2026 business standard mileage rate for the second half of the year. New Haven small business owners should separate vehicle records at the July 1 rate-change date.

The business rate is 72.5 cents per mile for January 1 through June 30, 2026. It is 76 cents per mile for July 1 through December 31, 2026.

This distinction matters for contractors, delivery operators, sales professionals, property managers, home-service businesses, consultants, and other owners who drive between job sites, suppliers, customers, and offices throughout New Haven County.

Apply the Correct 2026 IRS Rate!

Under IRS Notice 2026-10, the original 2026 rates were:

The IRS later issued Announcement 2026-11, published in Internal Revenue Bulletin 2026-29 on July 13, 2026. The revised rates apply beginning July 1, 2026:

The charitable rate remains fixed by Internal Revenue Code (IRC) §170(i). The revised medical and moving rates do not change the underlying eligibility rules. Moving mileage is generally limited to qualifying members of the Armed Forces and other specifically eligible taxpayers.

Review the IRS Standard Mileage Rates page before finalizing a return or reimbursement policy.

Calculate the Two 2026 Periods Separately!

Do not apply one annual rate to all 2026 business miles.

For example:

1. Record 4,000 business miles from January through June.
2. Multiply 4,000 miles by $0.725.
3. The first-period deduction is $2,900.
4. Record 3,000 business miles from July through December.
5. Multiply 3,000 miles by $0.76.
6. The second-period deduction is $2,280.
7. The combined mileage deduction is $5,180, before any separately deductible parking or toll expenses.

The IRS Announcement addresses deductible transportation expenses paid or incurred on or after July 1 and mileage allowances paid after that date for qualifying expenses. Maintain records that identify both the trip date and the related expense or reimbursement date.

September reminder: Reconcile January–June mileage now. Do not wait until December to reconstruct the first six months.

Separate Business Use From Personal Use!

A vehicle deduction is available only for qualifying business use. Personal driving must be excluded.

Business trips may include:

• Driving from one job site to another.
• Visiting a client or customer.
• Traveling to a business meeting away from your regular workplace.
• Driving to a supplier, warehouse, or trade location.
• Picking up materials or equipment.
• Making business deliveries.
• Traveling between a qualifying home office and another work location in the same trade or business.

Regular commuting is generally personal. The cost of driving from your home to your main or regular place of work is not deductible, regardless of distance.

For example, driving from your home to your regular New Haven office is generally commuting. Driving from that office to a customer in Hamden, a supplier in West Haven, or a job site in Branford may qualify as business transportation when the trip has a documented business purpose.

Do not treat a business phone call, client conversation, tools in the vehicle, or advertising graphics on the vehicle as proof that commuting became deductible. The underlying route and work-location facts control.

Review the transportation guidance in IRS Publication 463, Travel, Gift, and Car Expenses.

Choose Between Standard Mileage and Actual Expenses!

Business owners generally calculate vehicle deductions under one of two methods.

1. Standard mileage rate

Multiply qualifying business miles by the applicable IRS rate.

The standard mileage rate generally includes vehicle operating costs such as:

• Gasoline.
• Oil.
• Repairs and maintenance.
• Insurance.
• Registration fees.
• Depreciation or lease-related vehicle costs.

When the standard mileage method is used, these operating costs generally cannot also be deducted separately.

Parking fees and tolls related to business use may be deducted separately. Parking at a client meeting, tolls incurred on business travel, and similar charges should be recorded independently. Parking at your regular place of work remains a commuting expense.

2. Actual expense method

Under the actual expense method, calculate the business share of eligible vehicle costs. These may include:

• Fuel and oil.
• Repairs and tires.
• Insurance.
• Registration and license fees.
• Lease payments.
• Depreciation.
• Business-related interest where permitted.
• Business parking and tolls.

Divide business miles by total miles for the year. Apply the resulting business-use percentage to eligible costs. Personal costs must remain excluded.

Review first-year election rules

For an owned vehicle, the standard mileage method generally must be selected in the first year the vehicle is available for business use if you want the flexibility to use that method later. A later switch to actual expenses may be allowed, subject to depreciation rules.

For a leased vehicle, the standard mileage method generally must be used for the entire lease period once selected.

The standard mileage method is generally unavailable when:

• Five or more vehicles are used for business at the same time.
• Accelerated depreciation, the Modified Accelerated Cost Recovery System (MACRS), or a §179 deduction was claimed for the vehicle.
• A special depreciation allowance was claimed.
• Actual vehicle expenses were previously used for a leased vehicle after 1997.

Vehicles that are alternated rather than used simultaneously may be treated differently. Review fleet operations carefully. A business with five vans used by employees at the same time generally must use the actual expense method for the fleet.

Document Every Business Trip!

The IRS expects adequate records. Estimates and unsupported annual totals may be challenged.

For each trip, record:

1. Date of travel.
2. Starting and ending location.
3. Business destination.
4. Business purpose.
5. Beginning odometer reading.
6. Ending odometer reading.
7. Trip miles.
8. Vehicle identification.
9. Parking fees and tolls, if applicable.

A compliant entry should state more than “business.” Use a specific description such as:

September 4, 2026 : New Haven to Milford supplier : purchased materials for Elm Street installation : odometer 42,180 to 42,206 : 26 business miles.

Keep invoices, delivery confirmations, appointment records, purchase receipts, and toll statements with the mileage log. Those documents can corroborate the date, destination, and business purpose.

Start This September Tracking Routine!

Implement the following procedure immediately:

1. Record the current odometer reading. Date the entry September 4, 2026.
2. Create separate rate columns. Label one column “January 1–June 30” and another “July 1–December 31.”
3. Log each trip at or near the time of travel. Do not rely on memory.
4. Classify the trip before entering the miles. Mark it business, commuting, personal, medical, or charitable.
5. Reconcile the log every Friday. Compare mileage entries with calendars, invoices, fuel records, and customer appointments.
6. Store receipts electronically. Use a secure folder or client portal with monthly subfolders.
7. Separate parking and tolls. These expenses should not be buried in the mileage total.
8. Review the method before filing. Compare the standard mileage result with actual expenses if both methods are available.
9. Give the complete file to your tax professional. Include the vehicle purchase or lease documents and prior-year depreciation information.

A weekly review is more reliable than a year-end reconstruction. It also identifies personal and commuting miles before they are mistakenly included in the deduction.

Report Vehicle Information Correctly!

Self-employed owners generally report vehicle expenses through the applicable business return, such as Schedule C (Form 1040), Profit or Loss From Business (Sole Proprietorship). Vehicle information and depreciation details may also require Form 4562, Depreciation and Amortization (Including Information on Listed Property).

Form 4562 is used to:

• Claim depreciation and amortization.
• Make a §179 election when permitted.
• Provide information about the business and investment use of automobiles and other listed property.

Keep the vehicle’s date placed in service, total mileage, business mileage, commuting mileage, personal mileage, and business-use percentage available for preparation.

Connecticut note

Federal and Connecticut reporting may not produce identical results in every business structure. Connecticut treatment can depend on the taxpayer’s entity, income classification, depreciation treatment, and state adjustment rules.

Do not assume that a federal vehicle deduction automatically carries to the Connecticut return in the same form. Maintain the federal mileage log and actual-expense records for state review. Ask a qualified tax professional to evaluate the Connecticut filing treatment for your sole proprietorship, partnership, S corporation, C corporation, or limited liability company (LLC).

Protect the Deduction Before Year-End!

The July 1 rate change creates a straightforward administrative requirement: preserve the dates and mileage for every business trip.

For New Haven owners, that means documenting local travel across:

• New Haven and the surrounding municipalities.
• I-91 and I-95 business routes.
• Job sites throughout New Haven County.
• Supplier and warehouse visits.
• Client meetings and deliveries.
• Business parking and toll activity.

A precise record supports accurate tax preparation, financial reporting, employee reimbursement, and year-end tax planning. Incomplete documentation can reduce the allowable deduction, delay preparation, or lead to questions during an examination.

The IRS mileage rate is an optional method. It is not automatically the best method for every vehicle or business. Review the records, compare the methods, and apply the rate that matches the qualifying use and applicable rules.

Deadline reminder: Review September mileage records before the September 15, 2026 federal estimated-tax payment deadline if quarterly payments apply to your business. If you extended your 2025 individual federal return, the filing deadline is generally October 15, 2026. These filing and payment deadlines are separate from the requirement to maintain accurate 2026 vehicle records.
