What makes welders & skilled trades different from an ordinary filing?
Skilled trades frequently work through short host-country contracts where the treaty employment exemption is available only if the employer and cost-bearing conditions are satisfied — which subcontracting arrangements usually break. An ordinary preparer applies the general rule and stops there, which is how the relief in the specific provision goes unclaimed.
Can you work with my existing accountant?
That is how most of these engagements run. They keep the domestic file, we take the cross-border piece, and the boundary is agreed in writing so nothing is done twice or missed.
I work through a labour agency abroad — who withholds my tax?
Often nobody does, and that is the problem rather than the relief it looks like. The agency may be your employer of record at home while the site operator abroad bears the cost of your labour through the contract price. The treaty exemption for short employment abroad depends on both the employer condition and the cost-bearing condition being satisfied, and an agency chain usually breaks at least one of them. Once it breaks, the host country has a claim on the days you physically worked there, whether or not anyone deducted anything at source. The work is to establish which country the exemption fails in, file there, and claim relief at home rather than wait for a demand to arrive.
Does the treaty exemption still apply if I am subcontracted?
Usually not, or not on the terms you are expecting. The exemption is written for a worker sent abroad briefly by an employer at home, where the remuneration is not borne by anyone in the host country. Subcontracting inserts a party at the site who is effectively paying for your labour, and the cost then sits where you are working. When that happens the days you spent on site are taxable there from the first one, however short the contract was. It is worth reading the chain of contracts before the job starts, because the outcome is decided by paperwork you can still change at that point and cannot change afterwards.
Two countries taxed the same weeks of my work, can that be fixed?
Yes, and it is fixed by deciding which country had the right to tax those weeks rather than by splitting them down the middle. Overlapping contracts produce double taxation because each side looks only at its own days and its own payer. The order of work is to settle residence, then source each block of days to the place the work was physically performed, then claim credit in the residence country for tax properly paid in the other. Where a return has already gone in on the wrong basis, an amendment on one side is generally quicker and cheaper than arguing the point on both.
Why are my tool and travel deductions refused every single year?
Commonly because the claim is made in the country that has no taxing right over the income the spend relates to, or because nothing in the file connects the spend to a particular site. Trades expenses are allowed against the income they were incurred to earn, so a tool bought for a host-country contract belongs against host-country earnings. Records decide it: dated receipts, the contract they relate to, and travel dates that match the site log or the rotation roster. Claims reconstructed a year later, with no site record behind them, are the ones that get struck out first.
Do overlapping site contracts change where I am taxed?
They change the arithmetic rather than the rule. Each contract is looked at on its own terms — who employed you, who bore the cost, how many days you were physically in the country — and the answers can differ between two jobs that ran at the same time. One contract may qualify for the treaty employment exemption while the other fails the cost-bearing condition. That is not a contradiction, and a return that treats the year as a single block usually gets it wrong in both directions. Split the year by contract first, then by days on site, and file each country on the part it can actually tax.
Nobody withheld anything on my overseas site work, what now?
Treat it as an obligation rather than a windfall. Where the agency chain has broken the treaty exemption, the host country was entitled to tax those days, and no deduction at source does not remove the liability. It removes the only evidence you would have had that something was paid. Bring the years forward yourself: source the days, file where the right to tax sits, and claim the credit at home for the year the foreign tax is charged. Doing it in that order avoids paying twice while the two returns are corrected, which is the usual outcome when only one side is put right.
Do I have to file in both countries?
Frequently yes, and the two filings do different jobs. The country where the income arises taxes it at source; the country where you are resident taxes your worldwide income and then gives credit for the tax already paid. Filing only one side is what leaves relief unclaimed — the credit has to be asked for on a return. We prepare both sides so the numbers agree. See dual filing.
Is double taxation legal?
Yes. Nothing prevents two countries from taxing the same income under their own domestic law — each is exercising its own jurisdiction. What treaties and credit systems do is relieve the outcome rather than prohibit the charge, and relief is generally something you must claim on a return or a form, not something applied automatically. Miss the claim and the double charge stands. Double taxation explains the mechanism.
