IVA and the lodging tax: roughly 20% combined
Mexico charges 16 percent IVA on accommodation services, and the State of Guanajuato adds a 4 percent lodging tax, the Impuesto sobre Hospedaje, web-verified through Guanajuato state sources. On a USD 25,000 headline the two together add about USD 5,000 to the rental line, the heaviest tax layer in this cluster. A registered operator collects and remits both; an owner-direct rental outside the system may quote a rate that excludes one or both, so the all-in figures will not match unless you ask.
Private chef and staff: often included, dinners billed at cost
The San Miguel luxury tier is staff-heavy and much of it sits in the headline: a daily housekeeper, a cook for breakfast and lunch, and a gardener for the courtyards. A private chef for dinners runs USD 200 to USD 450 per service plus food at cost, with food landing at USD 25 to USD 60 per head, the local produce and the town’s deep culinary scene keeping it well below the US or Europe. A week of five chef dinners for ten runs USD 2,500 to USD 5,500 all in.
Car and driver: USD 120 to USD 220 per day
A private car with driver runs USD 120 to USD 220 for a full day, the practical way to move a group given the cobblestoned Centro and scarce parking. Most casonas in the historic center have no on-site parking at all, so a driver is closer to a necessity than a luxury for anyone staying centrally. Airport transfers from QRO or BJX run USD 130 to USD 260 each way.
Events and weddings: USD 3,000 to USD 30,000+ on top
San Miguel is one of Mexico’s leading wedding and celebration towns, and many casonas and fincas are built for events. A private chef dinner for a crowd, a mixologist and bar service, mariachi or a band, and event staff can add USD 3,000 to USD 30,000 and well beyond on a celebration week. If the trip is a wedding or a milestone, price the event programme as its own budget, not a line on the villa.
Gratuities: 10 to 15% of staff cost, USD 10 to USD 20 per staff per day
A cash gratuity of USD 10 to USD 20 per staff member per day, pooled and handed to the property manager on departure, is the practice at this tier. On a fully staffed casona with four or five resident staff that is USD 280 to USD 700 across a week, modest against the rental and genuinely valued.
