Married in 1895, Tata's husband was progressive and supported the education of his wife and daughter, hiring tutors to help her with her schooling.

When the reforms which were proposed failed to include women's suffrage, Tata and other feminists began protesting and publishing articles on the need for the vote.

Referred to the Southborough Franchise Committee to develop the electoral regulations for implementing the Montagu–Chelmsford Reforms, she wrote an article for The Times of India arguing that as some municipalities already allowed women to vote, extending the right was justified.

Compiling a report to substantiate the claim for suffrage, Tata and her daughter Mithan made two presentations to the government and traveled throughout the country to try to gain support for their cause.

She continued to work for voting rights and legislation protecting children until her husband was injured in an accident and required her care.

[11][13][14] As part of the delegation, Tata made an impassioned plea for women to be included as "people" and not prohibited from voting as if they were foreigners, children or lunatics.

[15] Suffragists prepared petitions and submitted them to legislatures and conferences[16] and published updates about the struggle in Stri Dharma, urging support for women's political empowerment as a part of the anti-colonial movement against Britain.

She wrote to influential people in a wide range of organizations to gain their support for the cause and was an active speaker at events.

[25] While in England, the Tatas spoke at various public meetings and events of British suffragists,[22] traveling to "Birkenhead, Bolton, Edinburgh, Glasgow, Harrowgate, Liverpool, Manchester and Newcastle" to gain the support of other women.

[11] They were also present for the final reading of the bill in December 1919, which included a clause that Indian provinces could enfranchise women if they chose to do so.

[2] Initially planning to stay through the end of the year, Tata and her daughter decided to remain in England when Mithan was accepted for post graduate studies at the London School of Economics.

Though not elected, Tata was proposed as a member of the international board, which was the first time Indian women could qualify for administrative positions in the organization.

[37] Much of her legacy was overshadowed by her more famous daughter,[4] but writer and activist Rita Banerji said Tata was one of the central figures in the fight for suffrage in India.
