Becoming Tax-Domiciled in Peru
Answer
The general rule applies to you
No exception is recorded for citizens of Mexico on this topic. That is the answer, not a gap - everything below is the rule you get, unchanged.

For a foreigner the test is a single day count: more than 183 calendar days in the country in any rolling twelve months. What makes Peru different is when it bites. Status is fixed at the start of each tax year and changes only take effect from the following one, so someone who crosses 183 days in, say, August becomes domiciled from 1 January - a built-in delay that only Colombia comes near, and only where the days straddle a year boundary. Until then only Peruvian-source income is taxed.
At a glance

- More than 183 calendar days
- Counting window
- Any rolling period of twelve months
- When the status starts
- 1 January of the following tax year
- Day counting
- Physical presence, arrival and departure days both count
- Absence counting
- Day of departure and day of return do not count
- Non-domiciled charge
- Peruvian-source income only
- Nationality
- Irrelevant to the test
Requirements
- More than 183 calendar days of residence or presence in Peru in any rolling twelve-month period makes a foreign individual domiciled
- Days are counted by physical presence, including the day of arrival and the day of departure, even if you were present for only part of the day
- Status is judged as it stood at the start of each tax year; a change during the year takes effect from the following year
- Until domiciled, you are taxed only on Peruvian-source income
- Once domiciled, the charge is on worldwide income
- Domicile is lost by acquiring residence in another country and leaving, or failing that, by being absent more than 183 calendar days in any twelve months
In detail
Same number, different clock
Peru and Colombia both use 183 days in a rolling twelve months, and both ignore nationality. They differ on what happens next. Colombia starts residency from the second year where the days straddle a year boundary; Peru always defers to the following tax year, whenever the threshold is crossed. Uruguay uses a calendar-year count plus three further independent grounds - family, income share, assets - none of which Peru has for individuals. Argentina attaches residency to the immigration permit rather than to a day count, so a permanent resident is tax resident from the start.
Why the lag matters more than the threshold
Because the change only takes effect from the following tax year, the cost of crossing 183 days is predictable and can be planned around. Someone who arrives in March and stays becomes domiciled from 1 January of the next year, with roughly nine months of Peruvian-source-only taxation in between. That is the opposite of Argentina, where the expensive surprise is that the status attaches silently after twelve months of temporary permits with nothing to file and nobody to tell you.
What applies to you
Nothing changes for a citizen of Mexico
We have no rule recorded that treats your citizenship differently here, so the general rule above is the one that applies to you. That is an answer, not a gap.
What the law says
«El inciso b) del artículo 7 de la LIR establece que se consideran domiciliadas en el Perú, entre otras, las personas naturales extranjeras que hayan residido o permanecido en el país más de ciento ochenta y tres (183) días calendario durante un periodo cualquiera de doce (12) meses.»Our translation - not official
Article 7(b) of the Income Tax Law provides that foreign natural persons who have resided or remained in the country for more than one hundred and eighty-three (183) calendar days during any period of twelve (12) months are, among others, considered domiciled in Peru.
Quoted from SUNAT's own binding opinion rather than from the statute page, because SUNAT publishes the consolidated law only as a scanned PDF whose machine-read text is unreliable. This is SUNAT restating the article it administers.

«De otro lado, el artículo 8 de la LIR dispone que las personas naturales se consideran domiciliadas o no en el país según fuese su condición al principio de cada ejercicio gravable, con arreglo a lo dispuesto en el artículo 7 de la LIR. Asimismo, establece que los cambios que se produzcan en el curso de un ejercicio gravable solo producirán efectos a partir del ejercicio siguiente.»Our translation - not official
Moreover, article 8 of the Income Tax Law provides that natural persons are considered domiciled or not in the country according to their status at the beginning of each tax year, in accordance with article 7. It also provides that changes occurring in the course of a tax year take effect only from the following year.
This is the provision that gives Peru its lag. Crossing 183 days in year one produces a worldwide-income charge only from 1 January of year two.

«se toma en cuenta los días de presencia física, aunque la persona esté presente en el país sólo parte de un día, incluyendo el día de llegada y el de partida. Para el cómputo del plazo de ausencia del Perú no se toma en cuenta el día de salida del país ni el de retorno al mismo.»Our translation - not official
days of physical presence are taken into account, even if the person is present in the country for only part of a day, including the day of arrival and the day of departure. For counting a period of absence from Peru, neither the day of leaving the country nor the day of return is counted.
The two halves of this rule are deliberately asymmetric and both work against the traveller: a day in Peru counts even if it is an hour, and a day out of Peru does not count if it is the day you flew.

SUNAT's reasoning for refusing to suspend the count during the 2020 border closure. The wider point holds: the 183 days run on their own, and no event - not force majeure, not a closed border - pauses them.

Practical notes
Migration status and tax domicile are separate questions in Peru: the day count does not ask what permission you hold, and holding a residence permit does not by itself make you domiciled.
SUNAT publishes the consolidated Income Tax Law as a scanned PDF; its machine-read text contains transcription errors, so every quotation above is taken from SUNAT's own binding opinion, which is published as clean text.
We have not read the rules on proving residence in another country in order to lose Peruvian domicile, beyond SUNAT's summary that a visa or a work contract of at least a year is used for that purpose.
Nothing here covers double-taxation treaties, which can change the answer entirely for someone with a competing residence.
