Opening a joint account with parents or a spouse? Read these five rules

Representative image

A joint bank account allows two or more people to operate the same account, pool income, pay shared bills and access funds during emergencies. For couples or ageing parents and adult children, it can simplify day-to-day finances. But Indian banks offer different “modes of operation,” and choosing the wrong one can expose you to blocked access, tax confusion or disputes later. The safest approach is to decide the rules upfront rather than fixing problems after something goes wrong.

Indian banks typically offer three operating choices: “Either or Survivor,” “Joint,” and “Former or Survivor.” Either or Survivor gives both people full access to withdraw, transfer and operate independently, while Joint requires signatures from everyone for every transaction. Former or Survivor is useful when a parent wants a backup operator but does not want the second holder to transact while they are alive. Pick the mode that matches the level of trust and control you want.

Nomination is often ignored because people assume a joint account will automatically pass to the other holder. That is not always true. If both holders die or if the surviving holder cannot operate the account, having a nominee speeds up access to funds. Without a nominee, legal heirs must produce succession documents that can take months. Updating nominees is free and can be done online with most banks.

The tax department does not care whose name appears first in the account. Taxation depends on whose income was deposited. If one partner adds all the funds and the other withdraws, the interest will still be taxed in the hands of the person who earned the money. For adult siblings or friends operating a joint account, documenting who contributes what helps prevent tax notices during an assessment.

If joint holders fall out, banks freeze the account the moment one person complains in writing. This means neither person can withdraw until the dispute is resolved. Similarly, if one holder dies, the operating rules decide who can access the money. Either or Survivor allows the surviving holder full access. Joint accounts, however, freeze until legal paperwork is completed. These rules matter far more than people realise, especially for ageing parents and adult children.

You can shift from Joint to Either or Survivor or update nominees at any time, but every account holder must sign the request and some banks insist on in-person verification. It is always easier to get the structure right on day one rather than fix a poorly chosen setup later. A joint account is powerful, but only when the operating rules match the relationship and future risks you are preparing for.
