Guides / Undeclared rental income

I rented it out and never declared it. What now?

This is the most common first email we get, and it almost always opens with an apology. It does not need one. Thousands of foreign owners rent out an Italian property for years without filing, usually because nobody told them they had to — the platform withheld something, the agency handled the keys, and no letter ever arrived from Italy.

The useful question is not how it happened. It is: what does fixing it cost today, and what does it cost if you wait?

The mechanism: ravvedimento operoso

Italian law has a built-in route for voluntary correction, the ravvedimento operoso. You file the missing return, pay the tax, and the penalty is reduced on a sliding scale — the earlier you come forward, the smaller it is. The crucial condition: it must happen before the Agenzia delle Entrate or the municipality formally starts on you. After that, the door closes and the full penalty regime applies.

Late by up to 90 days → penalty reduced to a fraction of the minimum.
Late by up to a year → still a deep reduction.
Late by several years → the reduction shrinks, but stays far below the assessed penalty.
After an assessment notice → no reduction. Full penalty, plus interest, plus collection costs.

What a typical three-year case looks like

Consider a flat on Lake Maggiore let long-term at €12,000 a year, never declared, with IMU also unpaid, and a rendita catastale of €700.

Flat tax due (cedolare secca 21% × 3 years)€7,560
IMU due (3 years, typical 1.06% rate)≈ €3,740
Reduced penalties and interest on voluntary correctiona modest surcharge

The same three years discovered by the tax office instead carry penalties that can reach and exceed the tax itself, plus interest running from each original due date, plus the cost of defending an assessment you cannot win on the facts. The difference between the two columns is usually larger than a decade of our fee.

Three things owners get wrong at this point

Assuming nobody can see it. Rental platforms report to the Italian tax authority. Banks exchange account information automatically across the EU, the UK, Switzerland and the US. Utility contracts, tourist tax registers and municipal short-let databases all point at the same address. Arrears are found; the only variable is when.

Filing only the last year to "start clean". A single fresh return on a property with a visible rental history is a flag, not a fix. The open years stay open and now have a signpost pointing at them.

Waiting for a quiet moment. Every month of delay adds interest and pushes the penalty reduction down a step. There is no version of this that gets cheaper by waiting.

How we handle it

You send us the property details, the years involved and what was received — no names of tenants, no platform logins needed at this stage. We come back with a written figure: tax, penalties and interest per year, and our fee, before you decide anything. If you go ahead, we file the missing returns, elect the flat tax where it is still available, calculate and pay the IMU arrears, and hand you a dated record of every payment. From the following year you are simply a normal client on the €470 subscription.

It is worth saying plainly: we are not a confessional and this is not a negotiation with the tax office. It is a procedure with published rules, and it works best done early and completely.

Tell us the years, not your name

Write to us with the property, the years and roughly what was received. You get back a written assessment of what regularisation would cost — before you commit to anything.
