The nomination process for the Tamil Nadu Assembly elections in 2026 officially began on Monday, with election authorities issuing detailed guidelines to ensure a smooth and transparent submission process. Candidates are allowed to use a maximum of three vehicles, which must be parked at least 100 metres from the Returning Officer’s office. Only the candidate and three accompanying persons can enter the office to submit nomination forms. The nomination window lasts eight days, but only four working days are available due to public holidays, prompting candidates to plan submissions carefully. The Election Commission of India (ECI) has introduced an online nomination submission option, although candidates must still submit physical copies in person. Each candidate must also provide a recent photograph and a sworn affidavit detailing their credentials by 3 pm on April 6, 2026, the final day for nominations. Key dates include the scrutiny of nominations on April 7, 2026, the last date to withdraw nominations on April 9, 2026, and election day on April 23, 2026. The results will be announced on May 4, 2026. With a competitive landscape featuring the DMK, AIADMK, BJP, NTK, and the debut of actor Vijay's TVK, candidates are urged to adhere strictly to the guidelines for a smooth nomination experience.
