Do non-residents have to pay advance tax in India?
Residence does not switch the instalment system off. What usually switches it off in practice is deduction at source: where enough tax has already been withheld on the Indian income, the instalment base is reduced and there may be nothing left to pay in-year. The problem is the income deduction never reaches — a capital gain, a receipt from a person who did not withhold, or income where the deduction taken is smaller than the tax it actually attracts. That is where a non-resident becomes liable for instalments without realising it, and interest accrues quietly until the return is prepared.
Tax was deducted at source — do I still owe instalments?
Deduction at source reduces the instalment base rather than replacing the system. You work out the tax on the whole year's income, subtract what has been deducted, and pay the balance in instalments across the year. If the deduction covers the liability, nothing more is due in-year. If it does not — because the rate applied at source is lower than your effective rate, or because some income was paid without any withholding at all — the shortfall carries interest for the period it was deferred. The common trap is income that produced a deduction certificate for part of the year only.
What happens if I miss an advance tax instalment?
Interest runs. India charges interest both for deferring an instalment and for falling short on the year as a whole, and it is computed from the instalment date rather than from the filing deadline, so it is already accruing by the time most people discover the problem. It is not a penalty in the sense of a discretionary charge to be argued about; it is arithmetic that follows automatically from the dates and the amounts. The remedy is to pay as soon as the shortfall is identified, because the charge is time-based and delay only adds to it.
How do I estimate instalments on income I cannot predict?
Estimation is the honest difficulty in this system. The working method is to set each instalment from what is actually known at that date, revise upward as the year develops rather than leaving the whole correction to the last one, and keep a written record of the estimate each instalment rested on. That record is what separates a considered estimate from a guess if the year is ever looked at, and it is nearly impossible to reconstruct afterwards. Income nobody could have foreseen, such as a gain on a sale that was not contemplated when the year began, is worth noting separately in it. Where a large receipt lands late, deal with it in the next instalment rather than leaving it to the return.
Does my foreign income count towards Indian advance tax?
It depends on residence, and that is the question to settle first. Where residence brings worldwide income into the Indian computation, the instalment base is the tax on all of it, not only on the Indian-source part, and that usually comes as a surprise in the year somebody's residence changes. The other half of the answer is what relief is available for tax paid abroad on that income, and the timing of that relief rarely lines up with the instalment dates. Both halves need working out before the first instalment, not after the year has closed.
Can foreign tax paid reduce my Indian instalments?
In principle relief for foreign tax reduces the Indian liability, and so the amount that needs paying in instalments. In practice the timing is awkward. The foreign tax may not be finally determined, or even paid, until after the Indian instalment dates have passed, so relying on it to reduce an instalment is a judgement about what the foreign return will eventually show. Where the estimate turns out low, interest follows on the shortfall. The safer approach is to estimate conservatively during the year and recover any excess through the return rather than carry interest.
Can I avoid capital gains tax on a foreign property?
Not by virtue of it being foreign — there is no exemption for that, and the "keep it offshore" advice you may have read is how people acquire penalties rather than savings. What genuinely reduces the gain is ordinary and legitimate: principal residence relief where the property qualifies and the designation is made correctly, a properly built cost base including acquisition costs and capital improvements, the timing of the disposition, the treaty rules for real property, and credit for the foreign tax paid. See principal residence and foreign property.
How many days can I spend in a country before I become tax resident?
It depends on the country, and a day count is only ever the start. Many use a threshold in a tax year, some also look at averages across several years, and some have no day test at all and decide on where your home and life are. Two countries can both conclude you are resident, which is what the treaty tie-breaker exists to settle. Counting days without checking the tie-breaker is how people end up filing as resident nowhere. See the residency tie-breaker.
