Getting your Indian income certified for a foreign mortgage application

When a bank abroad decides how much it will lend you, it runs a debt-to-income test: it adds up the income it is willing to count, sets that against your existing debts, and lends a multiple of the difference. The catch is the phrase "willing to count". An underwriter will only include income they can independently verify, and a stack of Indian bank statements in rupees, a rent agreement and an Indian tax return are not documents their system is built to read.

A chartered accountant's certificate solves that. It restates your Indian income in a single signed statement, on letterhead, expressed clearly enough that an underwriter who has never seen an ITR can rely on it. The figure is not asserted — it is tied back to your filed return and the records behind it, so the lender is trusting a regulated professional rather than your own summary.

The piece that makes the certificate portable across borders is the UDIN. ICAI requires its members to generate a Unique Document Identification Number on certification work, and anyone — including a foreign lender's verification team — can check that number on ICAI's public portal. That is what turns an Indian document into something an overseas underwriter is prepared to accept.

If you own property in India and let it out, your tenant or the managing agent usually deducts tax at source on the rent and reports it. That deduction shows up on Form 16A and in your Form 26AS / Annual Information Statement, and the rent itself is declared under "income from house property" in your return. A rental income certificate ties all of this together.

The CA states the gross annual rent, the standard deduction and any municipal taxes and home-loan interest that reduce it, and the net figure — then names the documents that support it. Because the rent reconciles to the TDS already deducted and to your filed return, the underwriter is looking at income the Indian tax system has already seen, not a number that appeared for the application.

Many lenders want the certificate to cover the last two or three years so they can see the rent is steady rather than a one-off, which is why the CA usually certifies a multi-year picture drawn from successive returns.

If your income in India comes from a profession or a business you run there — a practice, a consultancy, a proprietorship — the lender's question is different. They want comfort that the income is real, recurring and net of expenses, because a self-employed applicant has no employer payslip to fall back on. This is where a CA borrower letter does the work that a salaried applicant's Form 16 would.

The letter sets out the nature of the business or profession, how long it has been running, the turnover and the net profit (or, for a profession, the net professional receipts) for the relevant years, and confirms that these figures agree with the income tax returns filed for those years. Where the lender's form expects it, the CA can also comment on whether the income has been stable or growing, strictly on the basis of the filed figures rather than a forecast.

The certificate is issued on letterhead with a UDIN, names the returns and financial statements relied on, and avoids the one thing underwriters distrust — an opinion about future earnings. It certifies what the records show, which is exactly what a debt-to-income calculation needs.

Aarti, an NRI living in Toronto, is buying her first home there. Her Canadian salary on its own stretches the budget, but she also owns two flats in Bengaluru that are rented out, and her broker tells her the lender may count that rental income if it is properly certified. The underwriter's checklist simply says "CA-certified proof of foreign rental income, last 2 years".

A chartered accountant pulls Aarti's last two filed returns, her Form 16A and Form 26AS showing the TDS the tenants deducted, and the lease agreements. The CA then issues one certificate setting out, for each of the two years, the gross rent, the deductions, and the net income from house property — and confirms each figure reconciles to the filed return and to the TDS reported. It goes out on the CA's letterhead with a UDIN.

When the underwriter's verification team checks the UDIN on ICAI's portal and sees the income tie back to documents the Indian tax department already holds, the rental income goes into Aarti's debt-to-income calculation without a follow-up query. Exactly how much weight a given lender gives foreign rental income — full value, or a haircut — is the lender's own policy and varies, so the certificate is built to present the figures cleanly and let the underwriter apply their rules.
