Questions & Answers about A declaração do Imposto de Renda inclui o rendimento tributável.

Why is it do Imposto de Renda and not de o Imposto de Renda?

Because in Portuguese, de + o normally contracts to do.

So:

• de + o = do
• de + a = da
• de + os = dos
• de + as = das

Here, o Imposto de Renda is a masculine singular noun phrase, so de o Imposto de Renda becomes do Imposto de Renda.

Why are Imposto, Renda, and tributável capitalized or not capitalized this way?

In standard Portuguese, common nouns are usually not capitalized the way they often are in English titles or official expressions.

So in normal running text, you usually write:

• imposto de renda
• rendimento tributável

You may sometimes see Imposto de Renda capitalized in official, legal, bureaucratic, or stylistic contexts, but it is not required the way a proper name would be.

A learner should know that Portuguese generally uses fewer capital letters than English.
