Canarian taxpayers who purchased their primary residence in 2025 or previous years can benefit from a regional tax deduction that reduces their tax burden. This fiscal advantage, which covers the acquisition, construction, renovation, or expansion of the main residence, can generate significant savings for those who meet the requirements.

The deduction percentage varies based on the taxpayer's income and age. Those with a general and savings taxable income below 26,035 euros can deduct 5% of the invested amounts. For those exceeding this threshold but remaining below 46,455 euros, the percentage is 3.5%. Individuals under 40 years old receive increased percentages, up to 5.5% and 4% respectively. The maximum base for the deduction is 6,000 euros annually per taxpayer.

The deduction is applicable to mortgage loan amortization, interest paid to the bank, and certain insurance policies that are mandatory for financing, such as life or fire insurance. It also covers amounts paid for the construction of the primary residence or direct payments to the developer. General renovations are not included in this specific deduction, but other regional incentives exist for energy efficiency or adaptations for people with disabilities.

To access this benefit, the property must be the taxpayer's primary residence for at least three years, barring exceptions. The deduction follows the conditions that were in place before the general state deduction was eliminated in 2013. If public aid has been received, the deduction base will be reduced. This regional deduction can be combined with the transitional state deduction for purchases made before 2013, provided the total sum of deductions does not exceed 15% of the regional tax liability.
