The Income Tax campaign in Bizkaia, which begins on April 15, can seem like a cumbersome process for many taxpayers. However, Bizkaia's tax system offers a wide range of deductions and benefits that can reduce the final tax bill, particularly for groups such as tenants.

It is important to note that the draft tax return many residents will receive does not automatically include certain deductions, such as those for rent. Therefore, it is crucial to carefully review the tax authority's proposal before accepting it, to ensure all applicable deductions are included.

Tenants wishing to deduct the rent for their primary residence can apply a general deduction of 20% of the amounts paid, with an annual limit of 1,600 euros. This deduction increases to 35% (with a limit of 2,800 euros) for individuals under 36 years old, large or single-parent families, and people with disabilities.
