Ecuador’s SRI opens another September window to update expenses and adjust income tax

September will give Ecuadorian employees another opportunity to revise the information used to calculate their 2026 income-tax withholdings. The window applies when projected expenses, income or family dependents differ from the figures submitted earlier in the year.

The Internal Revenue Service, known as the SRI, allows workers to provide a new form to their employer in June and/or September under Resolution NAC-DGERCGC23-00000020. The update does not require every employee to file again. It is intended for people whose circumstances have changed.

A worker may have higher health, housing or education costs than originally expected. Salary or other income may also have changed, as may the number of people qualifying as family dependents. Employers can then recalculate future monthly withholdings, with the effect appearing in later payroll payments.

The rules cover projected spending on food, education, arts and culture, health, clothing, housing and domestic tourism at registered establishments. For 2026, taxpayers may also include food and health expenses for pets, as well as interest on unsecured loans known as quirografarios.

Family dependents can include parents, a spouse or domestic partner, and children up to age 21 or children with disabilities of any age, subject to legal conditions. The same person cannot serve as a dependent for more than one taxpayer. The September opportunity follows an earlier June window described on June 12, 2026.
