Renta 2026: key dates, deductions, and tips for couples
Starting April 8, the 2026 tax season is about to kick off, giving you nearly three months to settle accounts with the taxman and correct any discrepancies between the income tax paid and what's owed based on your earnings. Couples, in particular, need to double-check their options for saving extra cash.

Couples' tax filing: joint or individual?
For married couples, the choice between filing jointly or individually is crucial, with two key numbers to keep in mind: 3,400 euros and 8,900 euros. If one spouse earns less than 3,400 euros annually, it makes sense to file jointly, as the joint declaration comes with a 5,500 euro non-taxable benefit, plus a 3,400 euro deduction. This totals 8,900 euros in untaxed income.
Additionally, families with children can claim deductions ranging from 2,400 to 4,500 euros per child, depending on age and number of dependents. These deductions are automatically applied if your information is up to date.
It's recommended to both estimate and compare your tax liabilities under both joint and individual filing scenarios before making a decision. With the main filing deadline set for June 30, but no penalties for early submission, the sooner you file, the better.
Mark these key dates:
