Your first ninety days abroad: the financial things that have deadlines
Most relocation checklists are about logistics. Shipping, schools, the visa, somewhere to live, a phone number that works. Almost none of them mention that several financial decisions have a clock on them, and that a few get permanently more expensive the longer you leave them.
Why the first ninety days specifically
This page is the short list of things with deadlines. The full financial picture takes longer and can wait. What follows is only the parts where waiting costs money.
Three reasons, and none of them is urgency for its own sake.
Some paperwork is easier to obtain while you are still recently departed. Employers, banks and pension administrators respond faster to somebody whose file is current than to somebody who left four years ago.
Some elections have windows attached. Tax authorities, pension schemes and employer share plans all have moments where a choice is available and later is not.
And some costs rise with delay by design. Buying back missed pension contributions is the clearest example, and it is covered below.
Tell the country you left, and establish where you are now
Notifying the country you left is the item people skip, because leaving feels like an ending.
Most countries have a process for telling the tax authority that you have gone. Doing it starts the clock on your non-residency and creates the record you will need later. Not doing it leaves you looking, on paper, like somebody who never left.
That matters more than it sounds. Years afterwards, when somebody asks you to demonstrate when your residency ended, the evidence is either in a filing or it is in your memory. Only one of those is useful.
There is often a second, separate step covering the tax year of departure itself. That year is usually split, and it usually needs its own treatment.
Establish where you are now resident
Arriving somewhere does not automatically make you tax resident there, and the rules differ everywhere.
The practical question in the first ninety days is what evidence you are creating, rather than what your final position will be. Days present, where your home is, where your family lives and where your economic life sits are all things that get assessed later against records made now.
Two habits are worth starting immediately. Keep a record of your travel days from the beginning rather than reconstructing it in year three. And keep the documents that establish where you live, because you will be asked for them by a bank, an employer or a tax authority within eighteen months.
The record you cannot rebuild
Travel days, departure filings and address evidence are trivial to keep from day one and difficult to reconstruct in year three. Start the file in week one.
Check what your pension allows, and what it costs to wait
This is the one with the clearest arithmetic and the clearest penalty for delay.
Many home-country pension systems allow somebody who has moved abroad to keep contributing voluntarily, and doing so is often the cheapest return available anywhere in an expat finances.
The British case is the most concrete and it shows the shape of the problem. Voluntary National Insurance contributions can fill gaps in a record. In the 2026/27 tax year, Class 2 costs GBP 3.65 a week and Class 3 costs GBP 18.40 a week, against a full new State Pension of GBP 241.30 a week.
Here is the part that has a clock on it. If you pay for the previous tax year on Class 2, or the previous two tax years on Class 3, you pay the rate that applied to those years. For any earlier year, you pay the current rate. Rates rise. So a gap left unfilled quietly gets more expensive, and it does so on a schedule rather than gradually.
The equivalent question exists for Dutch, French, German and Australian schemes, with different mechanics and different windows. The instruction is the same: find out what yours allows, in the first months, while your record is fresh.
Share plans, banking and insurance
Read your employer share plan documents properly
If part of your pay arrives as stock, moving country usually changes something about it.
Dealing windows and blackout periods may differ under a new entity. Some plans treat relocation as a trigger for accelerated vesting or forfeiture of unvested awards. Some require a fresh election within a defined period after the move.
None of that is discoverable later. It is in the plan documents, and the time to read them is now rather than at the first vest after the move. Two questions are worth answering immediately. What happens to your unvested awards because of this move, and what changes about when you are allowed to sell.
Check what your bank does about a foreign address
Home-country banks and brokerages frequently restrict or close accounts held by non-residents. Some do it quietly and some do it with notice.
The account itself is rarely the problem. Closure often forces a sale at a moment you did not choose, and it can leave you without a home-country payment route at a point when you still need one. Find out what your existing providers do about a foreign address before you update it with them. That order matters.
Check whether your insurance still covers you
Life cover, income protection and critical illness policies often contain residency or travel conditions. A policy bought at home may not respond in the same way for somebody who now lives in another country. This one is usually quick to check and occasionally serious. It belongs in the first ninety days because the consequence of getting it wrong falls on somebody else.
Collect the documents while collecting them is easy
This costs an afternoon and saves a great deal later.
Get statements for every pension, investment account and policy you hold, dated around your departure. Get written confirmation of your leaving date from your employer. Keep the tenancy agreement or purchase document for wherever you now live, and the registration paperwork from the local authority.
The reason is unglamorous. Every one of those documents will be asked for by somebody within a few years, usually a bank, a tax authority or an adviser establishing your position. Obtaining them while your file is current takes days. Obtaining them in year six takes months, and occasionally proves impossible where a provider has merged, closed or lost the record.
The afternoon that pays for itself
Departure-dated statements, an employer leaving confirmation, your new tenancy or purchase document, and local registration paperwork. Days to gather now. Months, or impossible, in year six.

The financial items with a deadline attached when you move country, what each one costs if you wait, and the things that deliberately do not need doing yet.
What does not need to happen in ninety days
An equally useful list, because urgency applied to the wrong things is its own cost.
You do not need to restructure your investments immediately. Structure matters, but it is rarely time-critical in the first quarter, and decisions made before your residency position is settled tend to get made twice.
You do not need to move your pension. Transfers are permanent, and permanence deserves more than three months of context.
You do not need a new will in the first ninety days, unless your circumstances changed materially with the move. It needs review, and review can happen once the rest is settled.
You do not need to appoint anybody. Establishing the position comes first.
The order, in one paragraph
Notify the country you left. Start keeping records where you now live. Find out what your pension allows and what it costs. Read the share plan documents. Check the bank and the insurance. Collect the documents. Then stop, and let the rest wait until your residency position is actually settled.
Questions people ask in the first months
I have just moved. What is genuinely urgent?
Notifying the tax authority in the country you left, starting your day records, and finding out whether your pension contributions can continue. Everything else can wait a quarter.
Do I have to tell my old country I have moved?
Most countries have a process for it. Doing it establishes the record that supports your non-residency later, and reconstructing that evidence years afterwards is considerably harder.
Is it worth paying voluntary pension contributions from abroad?
Frequently, yes. The British case has an unusually clear return, and the cost rises for older gaps once they fall outside the recent-year window. The equivalent question is worth asking for every home-country scheme.
Should I move my investments straight away?
Usually not in the first ninety days. Structure decisions made before the residency position is settled often have to be revisited.
Will my bank close my account because I have moved?
Some providers restrict or close accounts held by non-residents. Check what yours does before you update your address, because a forced closure can trigger a sale at a time you did not choose.
What happens to my unvested shares when I relocate?
It depends entirely on the plan. Some treat relocation as a vesting or forfeiture trigger, some require a fresh election within a window. The answer is in the documents.
Work out which deadlines actually apply to you
A session covers your departure filing, your pension options and their cost, anything in your share plan triggered by the move, and what can safely wait. Thirty minutes is usually enough to separate the urgent from the merely important.
