New York → District of Columbia · Interstate 95 (New England Thruway)
What does it actually cost to drive from New York, New York, to Washington, District of Columbia? The hard numbers: 387 km (240 miles) of pavement primarily along Interstate 95 (New England Thruway), 3h 41m behind the wheel, and roughly $32.38 in fuel alone — that is 35.2 liters (9.3 gallons) of regular unleaded at a 0.92 USD/liter benchmark. Anyone leaving New York, the most populous US city and global financial capital, typically carries samples, signed proposals, or service equipment to deliver in Washington, the capital of the United States and seat of the federal government, and aims to be home the same evening. It is worth confirming whether the haul fits inside your daily hours-of-service window or whether an overnight at a midpoint hotel makes more sense. Applying the IRS standard mileage rate (2025) mileage rate of $0.43/km ($0.69/mile), the gross outbound reimbursement settles at $166.41. Attach the visit purpose, client name, and plate number to the Clara receipt so the journal entry lands directly in the business-travel expense account. For the US professional driving the 387 km (240 mi) between New York and Washington, reimbursement of $166.41 stays non-taxable to the employee when the employer follows an accountable plan under Treas. Reg. §1.62-2 and reimburses at or below the IRS standard mileage rate. US employers generally reimburse at the IRS standard mileage rate so the payment stays non-taxable to the employee under Pub. 463. Keep the IRS-compliant expense report (Form 1040 Schedule C, line 9) alongside the fuel receipt from any EIA-tracked retail station network pump used along the leg; Internal Revenue Service (IRS) examiners pull contemporaneous mileage logs first when auditing Schedule C unreimbursed business expenses, and the New York→Washington corridor must show date, business purpose, and odometer readings.
