Written for Mexico. This analysis applies to Mexican federal tax law — ISR (income tax), IVA (VAT) and SAT rules — and cites Mexican statutes. Amounts are in Mexican pesos (MXN).
"Should I buy or lease the car through the company?" is probably the most repeated tax question among Mexican business owners — and the only serious answer is arithmetic, because the law put different caps on each route and the result depends on the car's price. Here are the two complete regimes, the head-to-head numbers, and each one's traps.
Route 1 — Buying: investment capped at $175K
A purchased automobile is an investment deductible at 25% a year… on an original amount capped at $175,000 (combustion) or $250,000 (electric and hybrid) — caps under art. 36-II of the LISR (the income tax law), stable for years now (high-to-moderate confidence on the exact figure in force; verifiable in the current text). A $700K car deducts as if it cost $175K: ~$43,750 a year for four years, and the rest is non-deductible consumption. IVA follows the same proportion: you credit only the part of the IVA corresponding to the deductible amount (in the example, 25% of the IVA paid). The corollary that stings: on expensive cars, buying "through the company" deducts a small fraction — the real benefit is in the associated expenses, which are deductible in a proportion tied to the car's deductibility: fuel (paid through banking channels — cash for fuel is non-deductible by design), maintenance, insurance, tenencia (annual ownership tax).
Route 2 — Operating lease: rent capped at $200 a day
An operating lease (the lessor owns it and you pay to use it) deducts the rent up to $200 a day per vehicle (~$6,083 a month, ~$73,000 a year) — $285 a day for electric/hybrid (art. 28-XIII; same validity note). A $15,000-a-month rent deducts $6,083 and the rest doesn't — with creditable IVA in an equivalent proportion. Its advantages lie outside the cap: no capital tied up, fleet renewal, and the simple accounting of a recurring expense. The vocabulary trap that costs audits: a FINANCE lease is not this — a finance lease (with a purchase option set as the goal) is treated as an acquisition: you fall into Route 1 with its investment caps, not the $200 a day. Commercial "leasing" contracts mix legal forms — the correct classification of the contract IS the strategy.
The head-to-head arithmetic and the verdict by range
Maximum annual deduction: buying = $43,750/year (4 years, total $175K); leasing = ~$73,000/year every year, endlessly. The resulting ranges: a car up to ~$175-250K: buying wins or ties — you deduct 100% of the value and the asset is yours; a car from $400K to $1M+: the operating lease deducts more pesos per year ($73K vs. $43.7K) and forever — it dominates for tax purposes, and financially you pay for it (the implicit cost of leasing exists: compare rates, not just deductions); electric/hybrid: both caps rise ($250K / $285 a day) — the deliberate tax nudge that moves the balance up one segment. And the mother of all requirements, hanging over the entire analysis: strict indispensability — the vehicle must have a real relationship with the activity; the "company" sports car that lives at the partner's house is, on top of being a rejectable deduction, presumed income / a deemed dividend to the partner for the personal use of corporate assets. Labels: deducting the real operating vehicle through either of the two routes — safe; the family's personal fleet parked in the company — textbook red zone, visible from the balance sheet.
Renewing a car (or a fleet) this year?
The comparison with your numbers takes half an hour: the vehicle's price, your effective rate, the financing cost of leasing vs. your cost of capital, proportional IVA and the treatment of the associated expenses. For fleets, the right design (a buy/lease mix by unit type, a policy of bank-channeled expenses) is worth several points of total cost.

Frequently asked questions
Can I deduct 100% if the car is a 'utility' vehicle or pickup?
Cargo units and certain vehicles not considered 'automobiles' for these purposes escape the caps (they deduct their full amount at their category's rate) — that's why work pickups are the tax darlings of business owners. The technical boundary (what qualifies as an automobile vs. a cargo truck) is defined and verified per unit; it isn't a dealership's marketing label.
And if I use my personal car for the business — is anything deductible?
If you are an individual with business activity, your vehicle assigned to the activity falls under the rules with its caps and proportion of use. In a company, the clean scheme for a team member's car is different (work tools, or leasing the employee's vehicle to the company with its own treatment). What doesn't work: 'business' fuel and maintenance on a car that's in no scheme at all — the classic orphan deduction.
Is the $200-a-day cap per vehicle or per contract?
Per vehicle, per day. A fleet of 10 units = 10 caps. And the cap applies to a PURE (operating) lease — if your contract is a finance lease, your limit is the investment one ($175K/$250K) via the acquisition mechanics. Two contracts with the same monthly payment can deduct completely different amounts: read them with a tax magnifying glass before signing.
Is an electric car worth it just for the higher caps?
The tax side adds up ($250K of investment or $285 a day, plus the charging-station deduction incentive when it applies), but it's one factor among several: total cost of ownership, real use, infrastructure. The mistake would be buying it 'for the deduction' — the insight is that, if you were already torn between two options, the tax system is visibly pushing toward the plug.
