Dormant Companies: What You Still Have to File Even With Zero Invoicing

Many self-employed professionals and company directors assume that once a limited company stops invoicing, stops buying, and has no real activity, it’s enough to just “leave it parked” with no further paperwork. It’s one of the most common — and most expensive — mistakes we see day to day at the firm: a dormant company remains, for all legal and tax purposes, a living company until it is formally dissolved and liquidated before a notary and the Companies Registry. And that means obligations that don’t disappear simply because turnover is zero.

What Obligations Remain Even With No Invoicing

Filing a dormancy declaration with the Tax Agency (via the relevant census form) reduces some of the burden, but not all of it. Two obligations remain mandatory regardless of turnover:

The Corporate Tax return (Modelo 200). Every limited company, whether or not it is registered as active, must file Modelo 200 for as long as it hasn’t been formally wound up. Even if the result is zero or negative, it still has to be declared. It’s due within twenty-five calendar days after the six months following the close of the financial year — which for most companies coincides with the calendar year. Failing to file it doesn’t get you off the hook: it just triggers notices, surcharges, and, over time, penalties that pile up year after year.

Filing annual accounts with the Companies Registry. Preparing the accounts, approving them at a shareholders’ meeting, and filing them (balance sheet, profit and loss account, notes, and any other required documents) is mandatory for any limited company, dormant or not. The ordinary general meeting must be held within the first months of the year following the close of the financial year to approve the previous year’s accounts, and the filing must follow shortly after. A dormant company with blank accounts (assets, liabilities, and results all at zero) still has to file them — “nothing to report” isn’t a valid administrative shortcut.

The Real Risks of Just Letting It Die

Not filing Modelo 200 or annual accounts for several years running doesn’t make the company dissolve on its own. In practice, what actually happens is this. The Companies Registry can close the company’s registry file for repeated failure to file accounts, which then blocks almost any subsequent filing — from changing a director to the dissolution itself. The Tax Agency, for its part, can start a precautionary or ex officio deregistration procedure in the entities index, with knock-on effects on the tax ID and the associated bank accounts. And on paper, the penalties for not filing Corporate Tax on time keep accruing year after year, since they don’t lapse while the obligation is still alive.

What’s more, as long as the company formally exists, the director retains their duty of care. If losses pile up, there’s a legal obligation to call a meeting to dissolve the company or reduce capital once net equity falls below half of share capital; ignoring that can lead to the director’s personal liability for the company’s subsequent debts. “Abandoning” a company is never free — it ends up costing more than winding it up properly.

How to Properly Dissolve and Liquidate a Dormant Company

If the company has no activity and isn’t going to have any, the right path is formal dissolution and liquidation: a dissolution resolution at the general meeting, appointment of a liquidator (usually the director themself), settlement of the company’s assets and liabilities (if any remain), a notarised deed of extinction, and cancellation of the registry entries at the Companies Registry, along with the corresponding deregistration from the Tax Agency’s census. Only once the extinction is registered do the formal obligations actually stop. Until then, every year that passes adds one more pending filing to the pile.

At Zythos Business we support self-employed professionals and small businesses both with day-to-day bookkeeping and at these transition points: assessing whether it’s really worth keeping a dormant company going, bringing it up to date with the Tax Agency and the Registry if filings have fallen behind, or handling an orderly dissolution and liquidation from start to finish. The difference between sorting it out in time and letting it drift is usually measured in penalties avoided, not paperwork saved.
