DTAA + 15CA/15CB + Form 10F & 67: Pay Tax Once, Not Twice
Treaty beats domestic law — claim the lower rate with TRC + e-filed 10F. Outward remittance above ₹5L taxable needs 15CB (CA certificate). Foreign tax credit needs Form 67 by ITR due date. NRO repatriation: $1M/year.
DTAA claim checklist (lower TDS / refund)
- TRC (Tax Residency Certificate) from your country of residence + Form 10F e-filed on the Indian portal — both mandatory for treaty rates.
- Without documents, payers deduct at 20%+ (206AA) — claim the treaty rate later via ITR + TRC/10F.
- Treaty rates differ per country/article (commonly 10–25%) — check the specific DTAA + confirm with your payer/CA.
- Form 67 by the ITR due date — miss it and foreign tax credit (FTC) is routinely denied.
15CA vs 15CB (outward remittance)
| Situation | What to file |
|---|---|
| Taxable remittance ≤ ₹5L aggregate/FY | 15CA (Part A) only — no CA certificate needed |
| Taxable remittance > ₹5L aggregate/FY | 15CA (Part C) + 15CB from a CA first |
| Exempt categories (Rule 37BB list) | No 15CA/CB at all (bank may still ask — that's bank policy) |
| NRO repatriation (up to $1M/year) | Same 15CA/CB compliance + source-of-funds proof |
