Do I have to file at home while living in Germany?
Residence decides it, and residence is a question of facts rather than of where your post arrives. The one exception is US citizenship, which carries the filing obligation with the person wherever they go. So the first thing we establish is which system still claims you.
Is there a treaty between my country and Germany?
Possibly, and the version in force for your year is the one that matters — protocols and multilateral-instrument positions change what a treaty does without changing its name. We check it against the authority rather than a summary. Where no treaty applies, domestic relief takes over.
I own property in Germany. Where is the rent taxed?
In Germany, because that is where the property sits. The complication is the base: gross-rent withholding takes no account of mortgage interest, tax or repairs, so a leveraged property can face tax on turnover. An election onto net profit, where it exists, is what fixes that — and it has its own timing.
I work from Germany for a Canadian employer — who taxes my salary?
Start with where the work is physically performed. Employment income is generally taxed where the duties are carried out, so time at a desk in Germany points at Germany even when the employer, the contract and the bank account all sit in Canada. Residence then decides what the home country still wants to see: a resident reports worldwide income and claims relief for the German tax, a non-resident usually does not. The order matters. Settle residence first, then work out which country has the first claim on each slice of the pay, then deal with relief. Doing it in any other order produces an answer that has to be unwound later.
Which deductions on my German payslip can I claim as foreign tax?
Not all of them. A German payslip carries several deductions and a home-country credit claim only works with the ones that are genuinely income tax. Church tax and social contributions are not interchangeable with the wage tax line, and each has to be characterised before it goes anywhere near a claim. Work from the annual payroll statement rather than the monthly slips, because that is where the year is set out in a form the home return can use. And claim against the German tax finally charged, not the amount withheld during the year — those are rarely the same figure.
What is church tax and why is it on my payslip?
Church tax is a levy collected through German payroll from people registered with a recognised religious community. It is administered alongside the wage tax rather than being part of it, and that distinction matters twice for a cross-border file. It is the registration rather than the salary that triggers it, so it appears on the slip of new arrivals who were not expecting it. And because it is not income tax in the ordinary sense, it should not simply be swept into the figure a home return claims relief for. We read the annual statement and separate the lines before any credit is computed.
Do I still have to file at home while working from Germany?
In most cases yes, at least for the year you leave and often well beyond it. A home filing obligation does not end because you have started working from a German address. It ends when residence changes, and residence is decided on ties rather than on days alone — where the home is, where the family lives, what has been kept open and what has been closed. Until that question has been answered on paper, the safe assumption is that the home return is still due, that the German income belongs on it, and that relief is claimed for the German tax rather than assumed.
Why is my German withholding higher than my actual tax bill?
German payroll withholds by reference to a class assigned to your circumstances rather than a computed figure for your year. It is an estimate collected monthly, and the annual assessment is what finally settles the liability. Two consequences follow for a cross-border file. Timing: a home credit is based on what Germany ultimately charges, so a claim built on withholding is often wrong and has to be corrected. Evidence: the assessment is the document that supports the claim, so the home return either waits for it or is adjusted once it arrives. Plan for whichever of those two you prefer.
Can working from Germany create a tax presence for my employer?
It can, and it is the question employers usually ask late. One person working from a German address on behalf of a company abroad raises whether the company itself has become taxable in Germany and whether it should be operating a German payroll for that person. The answer turns on what the individual actually does there, how long the arrangement runs, and what authority travels with them — the treaty tests on a fixed place of business, and on the principal role leading to the conclusion of contracts, are the usual reference points. Settle it before the second year rather than after.
Is there a limit on the foreign tax credit?
Yes, and it is the whole design. To calculate the limit you compute the US tax on your foreign-source income in that category; the credit cannot exceed it, because its purpose is to stop double taxation, not to refund another country's tax. Pay a higher rate abroad than the United States charges and the excess is not lost but deferred, becoming a carryover for a year with room. Pay a lower rate and the credit simply covers the foreign tax. See Form 1116.
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.
