If only one parent is alive, can I claim just one dependent deduction?

Detailed explanation

Dependent deduction is calculated by actual number of supported relatives—single-parent scenarios are common. Provide relationship proof for the living parent; no deduction for a deceased parent is needed. Remittance proof should target the living parent you support. Do not fabricate information for deceased parents. Elderly dependent deduction depends on the living parent's age. This tool supports one or two parent estimates. The tax office reviews relationship authenticity.
