Short answer
You usually do not manually type every e-Fatura expense into the declaration. Rent and other deductions may be pre-filled or considered automatically when the underlying Portal das Financas data is correct. You still need to review the values and check whether Anexo H is needed.
What is usually automatic?
Expenses linked to your NIF, such as health, education, general family expenses, and some rent data, may already be available in Portal das Financas. The declaration process can use that data, but it is only as good as the invoices, rental reporting, and household details behind it.
When does Anexo H appear?
Anexo H is connected to deductions and tax benefits. It can appear when you need to review, confirm, or declare deductions and benefits rather than only accepting automatic treatment. The exact need depends on the data in your portal and the choices offered during filing.
What should I check before submitting?
- Whether your household members are correct.
- Whether rent appears under the right person and property situation.
- Whether e-Fatura expenses were classified correctly.
- Whether any deduction or benefit is missing or duplicated.
