How the DGT's position has evolved
Current position
To apply tax benefits for disability, it is essential to certify a degree equal to or greater than 33 percent through a certificate or resolution from the competent body. The status of dependency or caregiver does not substitute for the certification of the degree of disability required by the IRPF (Personal Income Tax) Regulations. In joint taxation, the disability increase is applied to the full employment income of the spouse with a disability during their period of activity.
The DGT's position remains constant in requiring the certification of a degree of disability equal to or greater than 33 percent. Throughout various rulings, the administration has specified that dependency or designation as a caregiver is not equivalent to the certification of the degree of disability. It has also clarified the application of this concept in joint taxation contexts and the need to prove the pre-existence of the disability in cases of death.
Turning points
-
Clarifies that a resolution of Grade III Great Dependency does not automatically equate to a degree of disability equal to or greater than 33%.
-
Establishes that, even if the disability resolution does not declare a date prior to death, other means of proof are admitted to certify the pre-existence of the condition.
