Is There a 183-Day Rule in Paraguay?

Where the number people quote comes from

Two figures circulate in this market and neither of them is a Paraguayan tax residency threshold for individuals.

183 days. This is the standard test in residence-based systems, and it appears in the domestic law of most of the countries our clients are leaving. It is not in Ley N° 6380/2019 as a test for individuals. People import it because it is the number they are used to.

120 days. This figure is repeated confidently by providers selling Paraguayan residency. It appears to derive from Ley N° 125/1991 Article 152, which concerns domicilio rather than fiscal residence. We have not verified that it operates as a residence test for individuals, and we will not assert either that it does or that no presence at all is required. If someone quotes it to you as settled law, ask them for the article and read it.

What the tax authority actually asks for

Resolución General N° 65/2020 sets out the requirements for the Certificado de Residencia Fiscal, and they are documentary rather than arithmetic:

Nowhere in that list is a number of days. What is there is your entry and exit record. The procedural detail, timing and validity are on the tax residency certificate page.

Why the migration record matters more than a rule of thumb

A day-count rule, where one exists, gives you a bright line to plan against. Paraguay's regime instead gives the authority discretion exercised on evidence, and the evidence is your actual movement record.

Consider two applicants. One spent 40 days in Paraguay in the fiscal year, has a lease, a family living in Asunción, a local bank account and a RUC with filings up to date. The other spent 200 days in Paraguay but entered and left through six countries, has no address, no RUC and no filings. There is no published rule that decides between them, and no honest adviser can tell you in advance how the file will be read. What we can tell you is that the file will contain both sets of facts.

The two questions people are actually asking

"How long do I have to stay to keep my residency?"

This is an immigration question, not a tax one, and it is answered by the migration authority rather than the tax authority. It is also the question with the more concrete answer: residency status carries its own conditions, its own renewal windows and its own consequences for prolonged absence, all of which sit under Ley N° 6984/2022. Start at the residency guide and, if you hold temporary residency, at the three-month conversion window, which is a genuinely hard deadline.

"How long do I have to stay to stop being taxed at home?"

This is a question for the country you left, and its answer is in that country's statute. The United Kingdom uses the Statutory Residence Test, which combines day counts with a ties test and is described in the UK leavers page. The United States taxes citizens regardless of days, which is covered in the US citizens page. Most European systems use a 183-day test alongside a centre-of-vital-interests test that can override it.

Notice that in every one of those cases the number you need is set abroad. Paraguay's silence is not the obstacle. Your home country's rule is the thing to plan against.

A practical way to hold this

1. Count days anyway. Keep a contemporaneous record of entries and exits for every country, not just Paraguay. It is cheap now and expensive to reconstruct.
2. Build facts, not just days. A lease, a cédula, a bank account, a RUC and filings are the things a file is made of.
3. Do not spend to a number nobody published. Structuring your year around "120 days" gives you the cost of the presence without the certainty you were buying.
4. Ask your home country's rule first. That is the binding constraint in almost every case we see.
