Tracks how much foreign tax credit is usable this year and how much carries, which is where unclaimed relief hides.
Enter your figures
An estimate for planning only. Rates and thresholds used here are the assumptions stated on this page; we confirm every figure against the issuing authority for your own tax year before anything is filed.
How the estimate is built
The credit is capped by the home tax on the same income, computed by category and by country rather than in total. Unused credit carries where the rules allow it and is lost where they do not, which is why the sourcing and category work matters more than the total foreign tax paid. Tracking the carryforward is the only way to claim it later.
How to get this moving
A calculator narrows the range; it does not settle a filing. If you already have an adviser, we will tell you what they should be asking rather than replacing them.

A named reviewer on every file
Every page on this site and every file we deliver says which practitioner reviewed it — a person, not a team inbox.

Two returns built against each other by one team, so relief is claimed exactly once and nothing falls between the two systems.
The order of filing is planned, not improvised
Which return goes first decides whether relief can be claimed at all. That sequence is worked out before anything is submitted.
You deal with the person who did the work
The practitioner who prepared and reviewed your file is the one who answers the question about it.
Cross-border tax case studies
Rebuilding an unused credit position across several filed years
A client had paid foreign tax on employment income for a run of years and each return had been filed without any carryforward schedule behind it. The work was to recompute the limitation for every one of those years on its own facts, category by category, then to establish what was unused at the end of each. The engagement produced a dated carryforward schedule tied to the foreign tax documents and assessments for each year, and corrected returns where the figure had to be carried through in order for a later claim to stand.
Separating two countries of tax into two limitation baskets
The filer earned salary taxed in one country and investment income taxed in another, and both sets of foreign tax had been added together on the return. We separated the two streams, computed the limitation for each country and category, and set out why the pooled figure could not stand. The result was a revised claim with the relief attributed to the stream it belonged to, and a written note of the sourcing reasoning, so the following year could be prepared on the same basis rather than started again.
A credit claimed against the wrong category of income
Relief had been claimed in full against domestic tax on a category of income that carried none of the foreign tax in question. The review traced each payment of foreign tax back to the income it was levied on, then recast the claim into the categories that could actually absorb it. Part of the relief survived in a different basket and part became a carryforward. The engagement produced a corrected return and a schedule showing which categories still had capacity, so later years had something to work from.
Sourcing reviewed after a credit was denied on assessment
A claim was disallowed on the footing that the income was not foreign-source. We went back to the contracts, the place the work was performed and the terms under which the payer accounted for it, and set out the sourcing position in writing with the underlying documents attached. The engagement produced a documented response to the assessment and a sourcing memorandum for the arrangement as a whole, which then governed how the following year was prepared rather than leaving the question to be argued twice.
Carryforward brought into a year with enough domestic tax
A client with an established unused balance had a year in which domestic tax on the relevant category finally rose enough to absorb part of it. The work was to confirm the balance still qualified, confirm the category and country it sat in, and order the claim so that the oldest usable amount was taken first. The engagement produced a claim supported by the year-by-year schedule, and an updated balance showing what remained and in which basket it would have to be used.
A yearly schedule built for a company with a foreign branch
A business with a branch abroad had been treating foreign tax as a single annual figure in its accounts. We built the limitation working into the year-end routine instead, splitting branch income and the tax borne on it into the categories the claim has to be made in, and tying each to the foreign filings. The engagement produced a maintained schedule that carries from one year to the next, and a short written procedure so the finance team assembles the same evidence each year without prompting.
Indian Rent Collected While Resident Somewhere Else
Rent from Indian property is taxed in India and again where you live, with relief on one side only. The file gets the Indian deduction right first, then claims the credit on the home return against what was actually paid.

Most notices are proposals rather than assessments, and they carry a response window that is shorter than it looks. The engagement reads what is actually being proposed, gathers the support, and replies inside the window with the position rather than a request for time.

Performance income is taxed where earned — Regulation 105 in Canada, withholding agreements in the U.S. — with special treaty articles overriding the usual rules.
Performance income is taxed where the performance happens, and the deduction is usually taken at source on the gross fee before expenses. Recovering the difference is a filing exercise in the other country, and it only works if the tour, the residency and the withholding certificates were documented while the work was being done.
