Good to Know
The rate presets are a commonly-cited convenience starting point, not this year's actual published IRS rate — always verify the current standard mileage rate before using this for an actual tax return or reimbursement request.

Calculating a Deduction From Miles Driven and the Per-Mile Rate
The standard mileage rate method estimates a tax deduction or reimbursement by multiplying
miles driven by a set per-mile rate — an alternative to tracking and deducting actual vehicle
expenses like gas, maintenance, and depreciation. Enter the miles driven and a rate per mile to
see the total deduction or reimbursement amount.
The IRS publishes a different standard mileage rate for each of three purposes — business,
medical or moving, and charitable driving — and updates them at least annually (sometimes
mid-year). The rate presets here are a commonly-cited convenience starting point, not this
year’s actual published rate — always check the IRS’s current published rate (linked above)
before using this for an actual tax return or reimbursement request.
Key Factors to Consider
Commuting miles are never deductible under any method. Your regular drive from home to a
regular workplace doesn’t count as business mileage — only driving beyond a normal commute (to a
client site, a second job location, or between work locations during the day) qualifies.
Choosing standard mileage vs. actual expenses is a real election with rules of its own. If
you deduct actual expenses (gas, maintenance, depreciation) for a vehicle in the first year you
use it for business, you generally can’t switch to the standard mileage rate for that same
vehicle in a later year — worth understanding the tradeoff before choosing a method the first
time you use a vehicle for business.
The IRS requires contemporaneous mileage records regardless of which method you use — a date,
the miles driven, and the business purpose for each trip. An estimate without documentation is a
real audit risk even if the math itself is correct.
Useful to Know
Most W-2 employees can no longer deduct unreimbursed mileage on their federal tax return.
Since the 2018 tax law changes, the miscellaneous itemized deduction for unreimbursed employee
business expenses is generally unavailable to most employees — this affects regular W-2 workers
who drive for work but aren’t reimbursed by their employer. The standard mileage deduction is
mainly relevant to the self-employed, along with a narrower set of exceptions (Armed Forces
reservists, qualified performing artists, and fee-basis government officials, among others). If
you’re a regular employee wondering whether you can deduct your own unreimbursed work mileage, the
honest answer for most people is no — check with a tax professional about whether you fall into
one of the narrow exceptions.
The Formula
Deduction/Reimbursement=Miles Driven×Rate Per Mile
Worked Example
Driving 1,000 miles for business at a rate of $0.76 per mile:
Deduction/reimbursement: 1,000×$0.76=$760.
Calcular una Deducción a Partir de las Millas Recorridas y la Tarifa por Milla
El método de la tasa estándar por milla estima una deducción fiscal o un reembolso multiplicando
las millas recorridas por una tasa fija por milla — una alternativa a llevar un registro y deducir
los gastos reales del vehículo, como gasolina, mantenimiento y depreciación. Ingresa las millas
recorridas y una tasa por milla para ver el monto total de la deducción o el reembolso.
El IRS publica una tasa estándar por milla distinta para cada uno de tres propósitos — negocios,
médico o de mudanza, y caritativo — y las actualiza al menos una vez al año (a veces a mitad de
año). Las tasas predeterminadas aquí son un punto de partida de referencia comúnmente citado, no
la tasa real publicada para este año — siempre verifica la tasa actual publicada por el IRS
(enlazada arriba) antes de usar esto para una declaración de impuestos o solicitud de reembolso
real.
Factores Clave a Considerar
Las millas de desplazamiento nunca son deducibles bajo ningún método. Tu recorrido regular
de casa a un lugar de trabajo habitual no cuenta como millaje de negocios — solo conducir más
allá de un desplazamiento normal (a la sede de un cliente, la ubicación de un segundo empleo, o
entre lugares de trabajo durante el día) califica.
Elegir entre la tasa estándar por milla y los gastos reales es una elección real con sus propias
reglas. Si deduces gastos reales (gasolina, mantenimiento, depreciación) para un vehículo en el
primer año que lo usas para negocios, generalmente no puedes cambiar a la tasa estándar por milla
para ese mismo vehículo en un año posterior — vale la pena entender esta disyuntiva antes de
elegir un método la primera vez que usas un vehículo para negocios.
El IRS requiere registros de millaje contemporáneos sin importar qué método uses — una fecha,
las millas recorridas, y el propósito de negocios de cada viaje. Una estimación sin documentación
es un riesgo real de auditoría incluso si las matemáticas en sí son correctas.
Útil Saber
La mayoría de los empleados con formulario W-2 ya no pueden deducir el millaje no reembolsado en
su declaración de impuestos federal. Desde los cambios en la ley fiscal de 2018, la deducción
detallada miscelánea por gastos de negocios de empleados no reembolsados generalmente no está
disponible para la mayoría de los empleados — esto afecta a los trabajadores regulares con W-2 que
conducen por trabajo pero no son reembolsados por su empleador. La deducción estándar por millaje
es relevante principalmente para los trabajadores independientes, junto con un conjunto más
estrecho de excepciones (reservistas de las Fuerzas Armadas, artistas intérpretes calificados, y
funcionarios gubernamentales a comisión, entre otros). Si eres un empleado regular preguntándote si
puedes deducir tu propio millaje de trabajo no reembolsado, la respuesta honesta para la mayoría de
las personas es no — consulta con un profesional de impuestos sobre si caes en una de estas
excepciones limitadas.
La fórmula
Deduccioˊn/Reembolso=Millas recorridas×Tarifa por milla
Ejemplo resuelto
Conduciendo 1,000 millas para negocios a una tarifa de $0.76 por milla:
It's a simplified way to deduct vehicle costs for business, medical/moving, or charitable driving — multiplying miles driven by a set per-mile rate — as an alternative to tracking and deducting actual expenses (gas, maintenance, depreciation, insurance).
Why does the rate differ by purpose?
The IRS publishes three separate standard mileage rates — business, medical or moving, and charitable — each reflecting different underlying cost assumptions and, for charitable driving, a rate set by statute rather than IRS calculation.
How often does the rate change?
The IRS typically updates its standard mileage rates once a year, though it has occasionally adjusted them mid-year in response to fuel price changes. Always check the current published rate rather than relying on last year's figure.
Can I deduct my commute to work?
No -- commuting miles (your regular drive from home to a regular workplace) are never deductible under any method. Only business-purpose driving beyond a normal commute qualifies.
Can regular employees deduct unreimbursed mileage on their taxes?
Generally, no. Since the 2018 tax law changes, most W-2 employees can no longer deduct unreimbursed employee business expenses, including mileage. This deduction is mainly relevant to the self-employed, with narrow exceptions for groups like Armed Forces reservists and qualified performing artists.
Does this account for parking fees and tolls?
No -- parking fees and tolls related to business travel are generally deductible separately, in addition to the standard mileage rate deduction, since the per-mile rate is meant to cover ongoing operating costs like gas, maintenance, and depreciation, not separate trip-specific fees. Keep receipts for these separately from your mileage log.
