Do the optimisation tips apply to my current tax return?

No, the optimisation amounts suggested are based on the tax return you have already created on taxx.lu. As the tax year is over, it is no longer possible to add new expenses or deductions for this period. In other words, these optimisations cannot reduce your tax already calculated for the past year.

These amounts are intended to give you an idea of what you could have saved if you had applied certain tax optimisations during the year.

However, you can use these tips for future tax years. If your situation remains similar, the amount of savings should be comparable.
