Losses
If you have made losses in past years, i.e. you had more expenses than income, you can carry forward these losses to later years and deduct them here.
Maintenance paid
If you pay alimony and/or child support to your ex, you can deduct 80% from your income.
Maintenance paid can be deducted up to 80% if
- you have a legal obligation under the civil code (or an analogous rule abroad) or under a court order to pay maintenance to an ex, (grand)children, (grand)parents, parents-in-law or children-in-law;
- the beneficiary is destitute;
- they don’t live with you;
- you pay regularly and the sums aren’t excessive.
You need to identify the person who receives the maintenance on p. 3 of your paper tax return. The tax authorities have warned they are going to pay particular attention to payments made to beneficiaries in other countries. Depending on the double tax treaty between Belgium and the country where the beneficiary lives, you may have to deduct withholding tax and pay that to the State.
Some planning opportunities
When one parent pays maintenance, she can take an 80% deduction for her payments if the children are domiciled with the other parent. However, she gets no allowance for dependents; the other parent will be entitled to the full allowance. They both pay less taxes, €100 paid in maintenance gives a tax reduction of about €40.
