The IUSI (Impuesto Unico Sobre Inmuebles) in Antigua Guatemala follows the same national rates as the rest of the country under Decreto 15-98. What’s specific to Antigua is who handles collection (the Municipality of Antigua Guatemala via its Catastro Municipal), where to pay (pagos.muniantigua.gob.gt or the Palacio del Noble Ayuntamiento), and the owner profile — Antigua has one of the highest concentrations of diaspora Guatemalans and foreign residents in the country, so the municipality is set up to handle remote payments and English-language inquiries.
Summary: Rates 0.2% to 0.9% of fiscal value per Decreto 15-98 (national). Quarterly or annual payments. Online portal pagos.muniantigua.gob.gt accepts international cards. Office: Catastro Municipal at the Palacio del Noble Ayuntamiento (4a. Calle Oriente y 4a. Av. Norte). Phone PBX 1552. Antigua has high diaspora ownership — the municipality is comfortable with remote payments.
IUSI Rates in Antigua (Decreto 15-98)
Rates are identical across the entire republic. Antigua does not apply an additional arbitrio on top of the IUSI. What varies is the fiscal value assigned by the Catastro Municipal to each property — and in Antigua, fiscal values for restored colonial properties in the historic center tend to be more up-to-date than the national average.
| Fiscal value bracket | Rate | Category |
|---|---|---|
| Q0 - Q2,000 | EXEMPT | No payment |
| Q2,001 - Q20,000 | 2 per millar (0.2%) | Low bracket |
| Q20,001 - Q70,000 | 6 per millar (0.6%) | Mid bracket |
| Q70,001 and above | 9 per millar (0.9%) | High bracket |
The rate is progressive by bracket — only the value within each bracket pays that bracket’s rate, not the entire value at the top rate. See the full legal breakdown in the national IUSI guide.
Example: Restored colonial home in central Antigua
A restored colonial home near the Parque Central with a fiscal value of Q800,000 (a common cadastral value for renovated downtown properties):
- Q0-Q2,000: exempt → Q0
- Q2,001-Q20,000 (Q18,000): 0.2% = Q36
- Q20,001-Q70,000 (Q50,000): 0.6% = Q300
- Q70,001-Q800,000 (Q730,000): 0.9% = Q6,570
- Annual IUSI = Q6,906 → quarterly payment approximately Q1,726.50 (~$220 USD)
For context: a comparable restored property in the USA might generate $8,000-$15,000 in annual property tax. Guatemala’s IUSI is one of the lowest property tax regimes in the Americas. Use the IUSI Calculator 2026 to calculate with any fiscal value.
Where to Pay the IUSI in Antigua Guatemala
The Municipality of Antigua Guatemala offers three channels:

The Muni Antigua payment portal accepts credit and debit cards, including international cards. You’ll need your matricula fiscal (cadastral ID) or numero de finca to identify the property. If you live abroad (USA, Canada, Europe), this is the most practical channel.

Diaspora: Owners in the USA and Other Countries
Antigua has a high concentration of owners who don’t live in Guatemala — Guatemalan diaspora, retirees from the USA and Canada, European investors. The Muni Antigua is set up for remote payments:
| Situation | What to do |
|---|---|
| I live in the USA and own a home in Antigua | Use pagos.muniantigua.gob.gt with an international credit card. You can pay the full year at once. |
| I don’t want to use a card — I’d rather have a relative pay | Authorize a relative in Antigua via notarized power of attorney. They’ll need the matricula fiscal and DPI. |
| I inherited a property and don’t know what’s owed in back IUSI | Request an IUSI statement of account from the Catastro Municipal with the finca number. Inherited debts roll over to the new owner. |
| I want to hire a gestor | Antigua has gestores known to the muni who charge Q100-300 per quarter to handle IUSI + Boleto de Ornato. Ask for a referral at the Catastro. |
| I want to know the real fiscal value of my property before selling | Request a constancia de valor catastral (cadastral value certificate) from the Catastro. Takes 5-15 days and costs Q50-200. |
CNPAG: Historic Center Conservation (Separate from IUSI)
Antigua Guatemala is a UNESCO World Heritage Site (declared 1979). That means in addition to municipal IUSI, any structural modification, facade work, paint color change, or anything visible from public streets requires approval from the CNPAG (Consejo Nacional para la Proteccion de la Antigua Guatemala). The CNPAG is NOT an additional tax on top of the IUSI — it’s a separate licensing and permits framework.
If you’re going to build, renovate, or change the facade of a property in Antigua’s casco urbano, you need:
- Municipal construction license — Muni Antigua
- CNPAG opinion — Consejo Nacional para la Proteccion de la Antigua Guatemala
- Current IUSI solvencia — from the Catastro Municipal
Without all three, the work is illegal and risks shutdown plus fines.
