Greece Tax Authority Denies Retroactive ENFIA Refunds

That asymmetry is rooted in a 2016 interpretation circular, POL. 1114/2016, which accepted a legal opinion saying late supplementary declarations could be used to increase tax obligations even after the state’s right to assess had lapsed. But the same logic has not been extended to refund claims. In practice, that means taxpayers correcting old property records may win when the correction benefits the treasury and lose when it benefits them.

For households and landlords, the cash impact can be material. An overdue correction that raises ENFIA can quickly snowball because late-payment interest is applied retroactively, potentially doubling the original amount due over long periods. A refund case, by contrast, is blocked outright, even where the original assessment was based on incorrect real-estate data. That creates a policy risk for the government: it may secure near-term revenue, but at the cost of appearing inconsistent and inviting fresh legal challenges from property owners.

Investors in Greek real estate and domestic consumption should not ignore the issue. Property tax treatment feeds directly into net yields for landlords, transaction economics for buyers and sellers, and household balance sheets in a market where recurring ownership costs already shape demand. If taxpayers conclude that past filing errors can only work against them, compliance behavior may improve, but confidence in the fairness and predictability of the system may weaken.

The broader backdrop is a tax administration still trying to reconcile revenue enforcement with legal certainty. The question now is whether courts or the finance ministry eventually force a more symmetrical approach, or whether the current “two standards” framework remains in place and becomes another cost for owners already carrying a heavier tax burden.
