Can I get back the tax deducted from my seasonal farm pay?
Often some of it, but only by filing a host-country return for the year the deductions were taken. Deduction at source is an estimate made by a payroll that assumes you work there all year. A season is not a year, so the estimate is usually too high once your actual host-country income for that year is worked out. Nothing is repaid automatically and nothing is sent to you to prompt it. Each year stands alone, so a missed year does not roll forward into the next one. Keep every pay statement the farm issues and the final summary for the season, because the return is built from those and rebuilding them later from memory is not possible.
Am I a resident of the country I work in or the one I live in?
Both can claim you, which is why the question is settled by facts rather than by choice. Most systems look at where your home is kept, where your family lives, where your possessions and bank accounts sit, and where you return when the work ends. A seasonal programme normally puts you in host-country employment from the first day, and that is a source claim on the wages. It is not the same thing as becoming resident there. Where both countries would treat you as resident, the treaty has a sequence of tie-breaking tests that decides which one gives way. That determination should be written down once and then used consistently on both returns.
My family stayed home while I worked the season, does that matter?
It matters a great deal, and it is usually the fact that decides the residence question. Where the household, the dependants and the permanent home remain in the home country, the centre of your personal and economic life has not moved, and the host country is generally left with a claim on the wages earned on its soil rather than on your worldwide income. That distinction changes what has to be reported where: the season's pay appears on both returns, but only one country taxes everything else you have. Say so on the record, with evidence of the home you kept and the family who stayed in it.
Do I get personal tax credits as a seasonal worker abroad?
Usually only in part. Personal credits and allowances are generally rationed for someone who is taxable in a country on a slice of income rather than on everything, and many systems restrict them by reference to how much of your total income for the year that country is taxing. The effect is that host-country tax on a season can be higher in proportion than a resident of that country would pay on the same wage. That is not an error to be argued away; it is how the restriction works. It also matters for the home return, because relief there is given for the tax actually and properly paid, not for what a resident would have paid.
Do I have to file in both countries if I only work one season?
Commonly yes, and for different reasons in each. The host country taxes the wages earned on its territory and has already taken deductions against them, so a return there both settles the liability and is the only route to recovering an over-deduction. The home country, if you remained resident there, taxes your income for the year including that season and then gives relief for the host-country tax. The two returns are connected: the figure the home country relieves is the one the host country finally assesses. Filing them in the wrong order, or filing only one, is what leaves the same wages taxed twice with no mechanism left to correct it.
I have worked seasons for years and never filed, what happens now?
Each year is dealt with separately, and the position is usually better than people fear, because over-deduction at source means several of those years may not carry a balance owing at all. The work is to establish for each season which country had which claim, what was actually deducted, and what the correct liability was. Older years can be closed by time limits in one country while remaining open in the other, so the sequence matters. Bring the pay statements, the season summaries and the dates of entry and departure. Where a disclosure route is appropriate, coming forward before a demand is issued is materially different from responding to one.
What happens if I have not filed for several years?
Missed years are handled as one package, not one at a time, because the route chosen for the first year determines the relief available for the rest. Each country has a disclosure or relief programme with its own conditions, and entering the right one — before the authority contacts you — is usually what keeps penalties down. Filing quietly outside a programme forfeits that protection. See catching up on missed returns.
How does a remittance actually work, and is it taxed?
A remittance is a transfer of money, not a category of income, and moving your own funds between your own accounts is not what creates tax. What can create tax is the income behind the money and the rules of the country it leaves. India, for instance, collects tax at source when a resident individual remits abroad under the Liberalised Remittance Scheme, and requires certification before certain payments leave. The transfer is the trigger for paperwork rather than for tax. See the LRS and tax collected at source.
