(4) After furnishing of Form No. 49, verification in respect of the following shall be done electronically: — (a) the assessee exercising the option is an eligible assessee; (b) the transaction in respect of which the option is exercised is an eligible international transaction; and (c) the exercise of option is valid.
(5) After verification, the assessee shall be intimated within a period of two months from the end of the month in which the option for safe harbour is exercised, about the acceptance or the rejection of the option exercised, as the case may be.
(6) The option for exercise of safe harbour shall not be rejected unless the assessee is provided an opportunity to remove defects, if any, in the application filed.
(7) Where an option for safe harbour is rejected electronically, the assessee shall be provided reasons for the same.
(8) Where an option for safe harbour is accepted, the assessee shall furnish return of income in accordance with the safe harbour provisions for each of the five consecutive tax years on or before the due date specified in section 263(1)(c).
(9) The option shall not remain in force in respect of any tax year, if the assessee withdraws the option for safe harbour, by furnishing a declaration to that effect.
(10) The withdrawal of option referred to in sub-rule (9) shall not be made after the expiry of six months from the end of the first tax year.

Rule breakdown
The five-year period and first-year threshold
The valid option remains in force for five consecutive tax years. The ₹2,000 crore aggregate-operating-revenue threshold is tested for the first of those five years.
Continue checking the applicable eligible-assessee, transaction and pricing conditions; the first-year revenue test does not excuse the other requirements.
Submit Form 49 to the specified authority
For the first year, furnish complete Form 49 to the Director General of Income-tax (Systems) by the stated return due date. The notified text refers to section 263(1)(c); verify the applicable current Act date and any valid extension.
The form is electronic, using digital signature or electronic verification code. It must be certified by the CEO or chairman and managing director and verified by the person authorised under section 265.
Electronic review and the opportunity to cure defects
Eligibility of the assessee and transaction and validity of the option are checked electronically. Acceptance or rejection is to be communicated within two months from the end of the month of exercise.
The option cannot be rejected without an opportunity to remove application defects, and electronic rejection must give reasons. Retain communications and respond to defect requests.
Annual returns and the four following-year statements
For each of the five years, furnish the return in accordance with safe harbour by the stated due date. In each of the four years after the first, also furnish the statement of eligible transactions, amounts and profit margins by that year’s specified return deadline.
Build a five-year calendar: the initial option and subsequent annual statements are distinct compliance steps.
Withdrawal has a narrow time limit and lasting effect
Withdrawal is by declaration. Sub-rule (10) states that it cannot be made after six months from the end of the first tax year. Check this precise first-year limit before relying on a withdrawal plan.
Withdrawal stops the option for the year withdrawn and subsequent years, and the assessee cannot opt again until the original five-year period expires. Do not assume an annual free exit and re-entry.
Other transactions remain separately reviewable
The AO can refer international transactions other than the eligible transaction under section 166. Keep the safe-harbour transaction scope clear in the books and supporting file.
Retain underlying transfer-pricing documentation and reports required by the wider framework alongside the option and annual statements.
