The 90-day campaign season for national candidates begins today.

Allowed to campaign starting Tuesday, 11 February are the 65 senatorial candidates and 156 party-list organizations.

Meanwhile, the 45-day campaign period for local candidates — including members of the House of Representatives and regional, provincial, city, and municipal officials — will start on 28 March.

Campaigning will pause on 17 April (Maundy Thursday) and 18 April (Good Friday).

The campaign period will end on 10 May, two days before Election Day.

Candidates for senators, House of Representatives, and local officials who do not belong to a political party can spend a maximum of P5 per registered voter.

If supported by a political party, the limit is P3 per registered voter in their constituency.

Independent candidates, on the other hand, are allowed to spend up to P5 per registered voter in their constituency.

Meanwhile, political parties are allowed to spend P5 per registered voter in the constituencies where they have official candidates. This amount is separate from the candidates' spending limits.

Candidates are prohibited from accepting campaign contributions from foreign nationals and corporations, government-owned and -controlled corporations (GOCCs), and entities funded wholly or partly by the government.

Private corporations are allowed to donate, but contributions should be accounted for and must be reported to the Comelec.

Certain sectors, such as public utilities and companies with government contracts, are prohibited from making contributions.
