OPM Legends Dulce, Randy Santiago and Zsa Zsa Padilla (March 11, 2019 – present) were added to the panel of judges this season. Dulce also serves as the head judge in some episodes.

Vhong Navarro, Anne Curtis, Amy Perez-Castillo, and Vice Ganda reprised their roles as hosts for the third season, with Ryan Bang, Jhong Hilario, Teddy Corpuz, and Jugs Jugueta serving as co-hosts as well as the Gong. Mariel Rodriguez-Padilla returned to fulfill her hosting duties this season.

Kim Chiu, Maja Salvador, Robi Domingo, Bela Padilla and Billy Crawford served as guest hosts in the absence of the main hosts.

Coinciding with the third year of TNT, the show unveiled three new changes in the competition.

The semifinals will take place at the end of the each quarter which will determine the two grand finalists that will take place in 2019. The two grand finalists will receive a medal and an additional ₱150,000 cash, while the remaining contenders will receive additional ₱25,000. The score will be composed of 50% coming from the judges and 50% from the text and/or online votes. A semi-finalist may be "gonged" during this stage and be eliminated from the competition.

This season, every judge will now have the power to return a losing Defending Champion from the Face-off Round using the Instant Resbak. The contestant who is given this power will then be saved and moves on to the Instant Resbak Week for a chance to participate in the rounds of the week-long grand finals (Ang Huling Tapatan). However, each judge is only entitled one save per season only (For example, if the judge uses his/her power in Quarter I, he/she can't use it again in the succeeding Quarters). Billy Crawford, Karla Estrada and Dulce did not award their Instant Resbak flags throughout the season.

The Instant Resbak Round follows the mechanics below:

• For the judges, they are not allowed to join the panel in the days that their contender will participate. They will personally coach their hand-picked contenders and watch them during the performance.
• Four contenders will face each day and two will be selected by the non-participating judges to advance to the next round.
• The top two will select one song from three songs prepared. The higher scorer will perform first. The winner will be decided by the average public and judge's score to advance to the final day.

The Instant Resbak week aired on September 2-6, 2019.

Losing semifinalists who are not gonged, and Instant Resbakers saved by the judges after the results, may still go forward to the week-long Grand Finals dubbed as "Ang Huling Tapatan" through the Ultimate Resbak Week as wildcards.[43]

All 16 Contenders will pick their songs and performed to get two slots for the Seat of Power who earned the Highest Text Votes and Judges Scores, and It will aired on the YouTube Channel of It's Showtime Online September 6, 2019, 6:00 PM.

The Ultimate Resbak started immediately after the final day of Instant Resbak Round, aired from September 7 to 14, 2019.

It uses the same format as the second season, where it follows a last man standing format.

Before the aired episodes, the semifinalists were pitted against each other to claim one of the two Seat of Powers. The Seat of Powers serves as immunity against the other contenders and gives them opportunity to select two semifinalists to pit against each other. The two contenders garnering the highest combined score from the public and judges will claim the Seat of Power. In the case where the judge's choice and the public's choice are the same person, the second placing contender for the public's choice will become the public's choice.

In the aired episodes, the two semifinalists who are in the Seat of Power picks one semifinalist each. The picked semifinalists will be pitted against each other for a chance to dethrone the semifinalists in the Seat of Powers. The winner of the first round is selected by the majority of the judges. The winner will now challenge one of the semifinalists in the Seat of Powers to go in a sing-off. The winner is based on 50% public vote and 50% judges' score. If the challenger wins, he/she dethrones the seated semifinalist. If the seated semifinalist wins, she/he remains in the Seat of Power. The remaining contenders in the Seat of Power will move forward to the week long Grand-Finals dubbed as "Ang Huling Tapatan" while the other contenders are eliminated.

Emil Sinagpulo (Luzon, Quarter II), Rose Ganda Sanz (Luzon, Quarter II), Marco Adobas (Metro Manila, Quarter III), Alliyah Cadeliña (Metro Manila, Quarter IV) and Shantal Cuizon (Luzon, Quarter IV) chose not to compete for the Ultimate Resbak due to their other priorities.

Due to the popularity of the Instant and Ultimate Resbak Rounds, the show added another phase, dubbed as Final Resbak. This will open one more slot for the Grand Finals, dubbed as "Ang Huling Tapatan".[45]

It follows the mechanics below:

• The resbakers were pitted against each other to claim the only Seat of Power. The Seat of Power serves as immunity against the other contenders. The contender garnering the highest combined score from the public will claim the Seat of Power.
• In the aired episodes, the resbaker who is in the Seat of Power picks three resbaker. The picked resbaker will be pitted against each other for a chance to dethrone the resbaker in the Seat of Power. The winner of the first round is selected by the majority of the judges.
• The winner will now challenge the resbaker in the Seat of Power to go in a sing-off. The winner is based on 50% public vote and 50% judges' score. If the challenger wins, he/she dethrones the seated resbaker. If the seated resbaker wins, she/he remains in the Seat of Power.
• The remaining contender in the Seat of Power will move forward to the week long Grand-Finals dubbed as "Ang Huling Tapatan" while the other contenders are eliminated.

Mariane Osabel from Mindanao withdrew to participate from the competition due to health problems.

After the Ultimate Resbak round, the week-long Grand Finals, dubbed as "Ang Huling Tapatan" (The Final Face-off), was originally scheduled from September 16 - 21 but was rescheduled to September 23 - 28, 2019, due to the addition of the new phase of the competition, the Final Resbak. It is the same as the previous season, but with modified results, used by voting percentages. The 13 finalists (now 12) from the 4 quarters and the resbak rounds will now compete for the title Grand Champion.[47] This is the first grand finals of the regular version without a finalist from Metro Manila, and the first one that with one contender withdrew.

Mariko Ledesma from Luzon withdrew to participate from the competition due to her personal reasons.[48][49]
