Once you buy a home in Dorado, Puerto Rico law gives you 30 days to report the new ownership to the Municipal Revenue Collection Center, known as CRIM. Buyers who miss that deadline can end up responsible for bills still issued in the seller's name, with interest and surcharges added.
Buyers coming from the mainland usually assume property tax follows the purchase price. If you pay more, the reassessment brings a bigger bill. Puerto Rico's system doesn't work that way. The price you pay in Dorado has almost nothing to do with what CRIM charges. What does shape your bill is a valuation formula fixed decades ago and a handful of filings made in the weeks around closing. That's where buyers get caught.
The 30 days after the deed is signed
Article 7.052 of the Código Municipal de Puerto Rico requires anyone who acquires property, whether by purchase, gift, inheritance or any other transfer, to report the change of ownership to CRIM on CRIM's form. The deadline is 30 days after the acquisition, and it applies whether or not the deed has been presented to the Property Registry.
If you miss it, the same article makes you responsible for receipts issued in the previous owner's name. That includes receipts for tax periods after your purchase, along with their interest, surcharges and penalties. You're also responsible for any tax lien already on the property when you bought it. CRIM doesn't cancel the old receipts. It amends them to show the new owner, and the interest and surcharges already charged stay in place.
That lien goes back a long way. Under Article 7.057, the tax for the current fiscal year and the five fiscal years before it is the first lien on the property, ahead of every other lien. It doesn't need to be recorded to bind the property. In practice, up to six years of a seller's unpaid tax can follow the house to its next owner. CRIM's online municipal portal offers debt inquiries, property certifications and online filing for ownership changes.
Why the bill doesn't follow the price
The 30-day rule matters so much because the tax itself is calculated so differently. CRIM's fiscal plan describes the method. Homes are valued at replacement cost as if they had been built in 1957, the last year Puerto Rico carried out a general valuation. A house finished last year is taxed as if it had been built then, using per-square-foot construction estimates for a comparable 1957 structure. CRIM calls these unit values "Unitarios."
Land works the same way. According to the CRIM fiscal plan, land is valued on its area, its characteristics and 1957 prices, and the calculation is "agnostic to the property location." The same document notes that most mainland residential assessments rely on recent comparable sales. In Dorado, that means the location premium built into a coastal or golf-course price is not an input to the tax calculation.
The Legislative Budget Office, OPAL, worked through an example in a May 2026 fiscal report. The report says CRIM Regulation 9129-2019 uses a 10.55% factor to adjust market value down to assessed value, and the example runs like this:
- Start with a market value of $161,400. That's the Census Bureau's 2024 estimate of Puerto Rico's median home value.
- Apply the 10.55% factor to get an assessed value of about $17,028.
- Subtract the principal-residence exoneration of up to $15,000 of assessed value. That leaves $2,028 of taxable value.
The same report lists Dorado's real property tax rate at 10.6% for fiscal year 2025–2026, against an average of 10.2% across municipalities. Of each taxpayer's rate, 1.03% goes to the State Redemption Fund. Multiplying OPAL's $2,028 taxable figure by that 10.6% rate gives roughly $215 a year. That's only an illustration. An actual bill depends on CRIM's own appraisal of the specific structure and land.
The rate is a high-sounding number applied to a very small base, so it tells you little on its own. For a buyer comparing homes, the useful questions are whether a property's CRIM record matches what's actually on the ground and whether its account is clean.
Improvements CRIM has never appraised
A structure adds to a property's assessed value only once CRIM has appraised it, so anything built after the last appraisal can be missing from the account. A pool, an added wing or a converted guesthouse might not appear in the property's assessed value. When CRIM eventually appraises the improvement, it bills back.
That billing period recently got shorter. Foro Noticioso reported on January 20, 2026 that CRIM's governing board had approved a resolution cutting retroactive collection from five years to two, counted from the date the improvement is appraised. According to that report, bills for unassessed improvements now cover the current fiscal year and one year back, under Article 7.041 of the Municipal Code. Previously, CRIM could issue retroactive bills going back as far as five years from when the improvement was made.
The same article described CRIM's effort to register structures that appear in its digital cadastre but have no identified owner and no assessment. CRIM labels these "John Doe" properties, has already assigned them taxable values, and is working with municipalities to identify who owns them. Javier García Cintrón, CRIM's interim director, asked property owners to find their property on the cadastral map and contact the agency's call center at 787-625-2746 if the owner field reads "John Doe." CRIM is also writing to owners of single parcels that hold several homes, which the agency calls "semilleros." Those owners are told to pay for the additional structures or to register each home separately.
When a Dorado home has been renovated or expanded over the years, any gap between its CRIM record and the house itself is a possible future bill. The two-year cap limits its size but doesn't make it go away.
The exoneration has to be filed
The principal-residence exoneration does a lot of work in OPAL's example. It removed about $15,000 of a roughly $17,000 assessment. Under Article 7.035 of the Code, as OPAL summarizes it, the exoneration covers up to $15,000 of assessed value. That's a reduction in taxable value, not $15,000 of tax. The Code limits it to one home per owner.
The exoneration doesn't transfer with the house. CRIM's AS-38 application form asks for proof of ownership and possession, such as the deed, plus a CRIM debt certificate covering all categories. The owner has to live in the home, or have qualifying family members live there without paying rent. The form's printed deadlines are January 31 of the year before the fiscal year you're applying for when the property already has a tax history, and 30 days after the sale for a home built for sale and assessed in the builder's name. The form is marked as revised in April 2018, so confirm the current deadlines with CRIM before you rely on them. The CRIM portal also accepts exoneration filings online.
New construction is the case to watch in Dorado, whether it's a residence finished by a builder or a home on a newly sold homesite. The 30-day owner-change notice and the 30-day exoneration window for a builder-assessed home run at the same time, starting the day you close.
Where the rules fall around a closing
This is general information about how Puerto Rico's property tax rules work. It isn't legal, tax or financial advice, so confirm your own situation with a Puerto Rico attorney, an accountant or CRIM directly.
In the order they come up, the rules above attach to a purchase like this:
- Before signing, the seller's open balance is what counts, because the tax lien covers the current year and the five years before it. CRIM issues debt certificates and property certifications through its portal.
- The CRIM record shows which structures have been appraised. Pools, additions and secondary structures that aren't on it can be billed later, now for up to two years.
- Within 30 days of the acquisition, Article 7.052 requires the ownership change to be reported to CRIM.
- For a principal residence, the AS-38 form asks for the deed and a debt certificate. A home bought from a builder has a printed 30-day window after the sale.
- Under Article 7.052, CRIM amends existing receipts rather than canceling them, so filing records matter later.
If a parcel has been divided, the Code allows CRIM, on written request, to split the tax, costs and interest among the new portions according to their value. Each owner is then responsible for the share assigned to their portion.
FAQ
Will my CRIM bill go up because I paid more than the last owner? Purchase price isn't part of CRIM's method. Assessments rest on 1957 replacement cost for structures and 1957 values for land. Changes to the property itself, such as a newly appraised improvement, are what move the assessment.
Is there an amnesty for back taxes on a property I'm buying? Not as of this writing. Senate Bill 1497 was filed on September 29, 2026, and was referred to committee on October 1, according to the legislature's SUTRA record. News is my Business reported that the bill would create a 90-day window in which paying the full principal of past-year property taxes would waive the accumulated interest, surcharges and penalties. To qualify, taxpayers would need to be current on the current year's tax or pay it along with the old debt. The bill is still pending and is not law.
Is Dorado's rate higher than other municipalities'? OPAL's May 2026 report lists Dorado at 10.6% for fiscal year 2025–2026. The average across municipalities is 10.2%, and neighboring Vega Alta is at 8.7% and Toa Baja at 11.8%. Because that rate applies to a 1957-based assessment, the condition of a home's CRIM record usually matters more than the rate itself.
When we represent a Dorado sale, the CRIM file gets the same attention as the inspection report: the debt certificate, the assessed structures and the filings that have to happen after closing.
