Gig-Work Mileage and Expense Records: What to Keep

Keep a contemporaneous mileage log

For each work trip or clearly defined work segment, record the date, starting and ending odometer readings, destination or route as appropriate, and specific business purpose. Record the business miles separately from personal miles. If the trip includes both personal and work use, make the split clear rather than treating the entire trip as business. A note such as “delivery work between restaurant and customer” is more informative than “driving.”

Record odometer readings close to the time of travel rather than reconstructing an entire year later. Keep beginning- and end-of-year odometer readings or other records needed to support total annual vehicle use, along with the work entries. Preserve records that support the mileage, including platform or calendar records if relevant, but do not assume an app shift log alone replaces a mileage record.

The mileage amount for a tax return depends on the rules and method that apply to your circumstances. A record is evidence of what happened; it is not an automatic determination that a trip is deductible. Check current IRS guidance and ask a qualified tax professional if eligibility or method choices are unclear.

• Date of each trip or business segment.
• Odometer reading at the start and end, with miles calculated from those readings.
• Business purpose and destination or route detail sufficient to explain the trip.
• Business and personal miles identified separately when use is mixed.
• Supporting annual odometer and trip records retained with your tax records.

Illustrative mileage log example

The example below shows the kind of detail a record can contain. It does not determine whether the trip qualifies for a deduction, and its readings and mileage are made-up teaching figures.

Keep expense details and receipts outside the app

For each expense, record the transaction date, amount, vendor, what was purchased, and the business purpose or allocation method. Preserve the original receipt or other supporting record outside GigOptimizer. Premium includes CSV and printable downloads of manual expense entries; these are not filed tax documents. Where private storage is enabled, Premium also supports one JPEG or PNG receipt photo per expense, up to 5 MiB and 100 saved photos per account. Saved photos remain owner-viewable and removable after Premium ends. The app does not extract receipt text or import bank transactions. A typed amount or a normalized photo is not a substitute for retaining the original documentation.

Separate clearly business-related purchases from personal purchases. For mixed-use items such as a phone or vehicle, keep the basis you used to allocate the business portion and supporting records. Do not assume that choosing a category such as gas, maintenance, insurance, or supplies makes the full amount deductible.

For vehicle costs, retain records for fuel, repairs, maintenance, insurance, and other relevant costs if you use a method that requires them. Depreciation and vehicle-use records can involve additional rules. Keep business miles and total miles available to support the business-use share where needed. Keep parking and toll records too; IRS guidance discusses their treatment separately in some circumstances, but they are not a blanket exception allowing every vehicle cost to be claimed on top of mileage.

• Save receipts, invoices, statements, and other source records in a place you control.
• Enter the transaction date, amount, vendor or description, and business purpose.
• Document the allocation for items with both personal and business use.
• Keep records of vehicle costs and annual total/business mileage relevant to the method used.
• Do not discard records because an amount was entered into a tracking app.

Understand the vehicle tax-method distinction

IRS guidance distinguishes the standard mileage method from the actual expense method. They are different approaches with rules about eligibility, records, and which costs can be included. The standard rate is a tax deduction method, not a statement of the amount of cash you spent on a trip. The actual expense method considers applicable vehicle costs and business use under IRS rules. Do not add overlapping vehicle costs twice by claiming a mileage allowance and also treating the same gas, maintenance, insurance, or depreciation as additional actual vehicle deductions.

Parking fees and tolls may receive separate treatment in some cases; consult the IRS rules for the applicable year and circumstances. That limited distinction does not mean every vehicle-related payment can be stacked on top of the standard mileage method. Keep receipts and records even when you are uncertain which approach you will use, then get advice before filing if needed.

For 2026, the IRS announced a business standard mileage rate of 72.5 cents per mile. The IRS current standard mileage rates page is useful for checking the applicable rate by year, and the dated announcement states the specific 2026 figure. A rate is year-specific and must not be confused with a personal estimate of per-mile cash cost.

Illustrative expense and rate examples

Suppose a driver keeps a receipt for $48 of fuel and a separate mileage log for a work period. The $48 is an illustrative cash purchase, not automatically an allowable deduction under every method. If the driver uses a method that accounts for vehicle costs through a mileage rate, adding the same fuel as an additional vehicle deduction may overlap. A qualified tax professional can help apply the rules to the driver's facts.

At the announced 2026 rate, 100 eligible business miles multiplied by $0.725 equals an illustrative $72.50 standard-mileage calculation before considering any separate applicable items or other rules. This arithmetic does not establish that the miles are eligible, that the user may use the method, or that $72.50 is tax savings. A deduction is not the same as a reduction in tax by the same dollar amount.

Use a manual log without mistaking it for tax software

GigOptimizer lets users manually enter mileage dates, starting and ending odometer readings, purpose, and notes, and manually enter expense categories, dates, amounts, and descriptions. It does not automatically track GPS, import earnings or mileage from gig platforms, or upload receipts. Keep original receipts and supporting records somewhere outside the app.

There is an important rate limitation: the app's mileage defaults and settings use whole cents, while the IRS 2026 business rate is 72.5 cents per mile. The current setting cannot accurately represent that fractional-cent rate. Do not enter a rounded substitute and treat the result as an exact 2026 IRS calculation. Its Financial Overview also combines logged expenses and a mileage allowance, which can overlap vehicle costs; it is not an exact cash-profit worksheet or a precise tax estimate.

Free accounts can store up to 15 mileage records and 15 expense records at a time, and up to 10 shifts. These are stored-record caps, not monthly allowances; Premium has separate limits. Plan how you retain your complete supporting records independently. For a related explanation of cash margin versus tax deductions, see the guide “How to Calculate Gig-Work Profit Per Hour.”
