El cálculo es bastante directo. Se toma la base imponible (el valor del vehículo) y se aplica una The calculation is pretty straightforward. You take the taxable base — basically the vehicle's value — and slap a straightforward 1% rate on it. But there's always a minimum you can't go under: no matter what, the tax won't be less than 1.5% of the UIT (that's the Unidad Impositiva Tributaria) that's in force on January 1 of the year you're paying for.
For 2026, the government (through the MEF) fixed the UIT at S/ 5,500 — you can double-check that on the official SUNAT or MEF websites if you want. So the smallest amount anyone ends up paying is roughly S/ 82.50 (yeah, just 1.5% of 5,500 — simple multiplication). Some municipalities tweak the final number a couple of soles up or down because of their rounding habits, but S/ 82.50 is the ballpark figure pretty much everyone sees as the real minimum.
The municipality uses the higher of:
The MEF updates this table every year, factoring in make, model, version, year of manufacture, and sometimes adjustments for age.
Taxable Base for the Vehicle Tax
The taxable base is essentially the commercial value of the vehicle at registration: brand, model, year, version—everything that sets its real price. The 1% rate applies to that, but always respecting the legal minimum. You can hop over to the MEF website and check their latest reference table for vehicle values, or — if you’re in Lima — just use the SAT’s online calculator. Either way, it’ll give you a spot-on idea of exactly how much you’ll end up owing.
For first-time declarations or changes, they might ask for more, but regular payments are straightforward with these.
Most places now let you do it fully online through their portals or apps (like the SAT's Virtual Agency), or at authorized banks, municipal cashiers, or agents. You can pay in full (often due by late February/March) or split into up to four quarterly installments.
Daily late interest starts piling up on the debt.
You’ll get slapped with fines right away — for not declaring on time or just straight-up not paying.
Then the municipality can kick things up a notch with coercive collection: they might garnish your accounts, put liens on stuff, or go after whatever they can legally touch.
But honestly, the absolute worst part? You won’t be able to sell or transfer the car without major headaches. The debt pops up right there in the SUNARP registry, and no buyer in their right mind is going to take it on until you’ve cleared every last sol. It basically freezes the car until you sort it out.
Bottom line: ignoring it gets expensive and creates unnecessary stress.
The best approach? Just make it a habit to check once a year—take a quick look at the latest MEF reference table and your municipality’s website, declare if you need to, and pay right away. That keeps everything running smoothly and spares you those unpleasant surprises down the line.
If you’re not sure exactly how much you owe for your specific plate or model, don’t guess—head straight to the SAT (if you’re in Lima) or your local municipal office. They’ll run the numbers for you and give you the precise amount.
