Who files Form 7004, the company or its owners?
The entity does, for its own return. Form 7004 is the automatic extension for business, partnership, trust and corporate returns, so it belongs to whichever entity is asking for more time, and each entity in a group asks for itself. Owners and partners have their own returns and their own extension routes, and one request made by the parent does not sweep up its subsidiaries or the partnerships beneath it. A frequent failure in a group is not a missed form but a missed entity: everything was extended except the one nobody had on the list.
Does Form 7004 give us more time to pay the tax?
No. The extension protects the filing, not the payment. That distinction does real damage every year, because an entity that believes it has bought itself months discovers that the liability fell due on the original timetable and only the paperwork moved. Treat the extension as separating two dates that used to feel like one: the date the return goes in, which has moved, and the date the liability has to be met, which has not. Where an entity is waiting on overseas figures, we quantify the liability well enough to meet it while the return itself is still open.
Does the extension also cover the forms that go with our return?
Not in every case, and that is the assumption worth testing before you rely on it. The extension protects the filing it was requested for; the information returns that travel alongside a business return do not all follow it automatically. So an entity can be properly extended on its main return and still be late on something that accompanied it, which is a poor outcome because the exposure on those filings does not depend on tax being owed. We list an entity's whole filing set once, mark which items the extension reaches, and keep that list with the calendar.
Our foreign parent closes its books late, can we extend every year?
Routinely, and it is one of the ordinary reasons the extension exists: entities very often need more time because a foreign parent or subsidiary closes its books on a different calendar. What we would not do is treat the extension as the whole answer. In a cross-border group the binding constraint is usually the foreign audit timetable, and that is worth mapping before the season starts rather than discovering each spring. Once the two calendars sit on one page, most groups find that some entities need the extension every year, some occasionally, and some never did.
Do we need to give a reason to get the extension?
The extension is automatic in the sense that it does not depend on persuading anyone that your reason is good enough. What it depends on is the request being made properly and in time, for the right entity and the right return. That shifts the risk from the merits to the mechanics, and the things that go wrong are mechanical: the wrong entity identified, a return type that does not match the entity, or a request made once the time it was meant to extend has already run out. We check those before lodging rather than after.
Can one Form 7004 cover every company in our group?
No. Each entity extends its own return, so a group with corporations, partnerships and a trust inside it has a set of requests to make rather than one. Groups are caught here because the group feels like a single taxpayer internally, with one finance team, one set of books and one closing timetable, while the filing population is a list of separate entities. The practical fix is a schedule of every entity, the return it files, and whether it is being extended this year, kept by the person who closes the books rather than remembered each spring.
What is a permanent establishment, and how easily do we create one?
A taxable presence in another country under the treaty — typically a fixed place of business such as an office, branch, factory or workshop, or a dependent agent habitually concluding contracts on your behalf. Some treaties add a services test measured in days. Purely preparatory or auxiliary activity is excluded, but that carve-out is narrower than it sounds: one senior employee working from home in the other country, with authority, has been enough. See business profits and permanent establishment.
I work remotely from another country for a company back home — who taxes me?
Usually the country you are physically in, because employment income is generally sourced where the work is done, with your residence country taxing it as well if you are resident there and giving credit. Three things follow: your employer may acquire withholding and social security obligations where you sit, a treaty tie-breaker may be needed if both countries call you resident, and a short trip that becomes a long stay can cross a residence threshold nobody was watching. See remote workers and digital nomads.
