From 2 February, the fee for a standard online passport application, made from within the UK, will increase from £75.50 to £82.50 for adults and from £49 to £53.50 for children.
Postal applications, meanwhile, will increase from £85 to £93 for adults and from £58.50 to £64 for children. The proposals are yet subject to parliamentary scrutiny.
HM Passport Office said the new fees would help the Home Office "move towards a system that meets its costs through those who use it" and reduce support for passport services from general taxation.
It stressed: "The government does not make any profit from the cost of passport applications."
