BRASILIA, Jan 12 (Reuters) - Brazilian Finance Minister Fernando Haddad announced on Thursday a package of measures to increase revenue and cut spending in order to reduce an estimated primary deficit of 232 billion reais ($46 billion) in this year's budget.

Among the measures are changes to rules about how companies can generate tax credits with the ICMS state tax, which is expected to increase federal revenues by 30 billion reais this year.

Haddad also announced a tax debt renegotiation program, providing for discounted fines and interest on installments, which could boost government revenues by 50 billion reais in 2023. (Reporting by Marcela Ayres Editing by Chris Reese)
