The threshold for means of subsistence used to determine whether a child qualifies as a dependent is increased to €12,000 and is now uniform across all categories (indexed for tax year 2026; base amount €5,265). Doctoral grants will also be considered to determine whether a child can be dependent.
Children who earn professional income that parents deduct as a business expense cannot be considered as dependent. This is also the case they would earn a living wage.
The following tax benefits will be abolished from 1 January 2025 (unless otherwise stated):
- Reduction for remuneration paid to a domestic servant

The amounts of the following tax reductions or deductions will be frozen from 2025 until tax year 2030:
- The exempted first tranche of:
- interest income on savings account
- dividend income
- interest income received from a company with a social purpose
- interest income received from loans through crowdfunding platform
- The maximum amount of federal long-term savings
- The maximum amount linked to the acquisition of employer’s shares
- The maximum amount linked to the gifts.
It was also the intention to freeze the indexation of the tax reduction for pension savings, but this will be postponed to assessment year 2027. Consequently, the following maxima apply for income year 2025: - up to 1.050 EUR resulting in a tax relief of 30%
- up to 1.350 EUR resulting in a tax relief of 25%
- The maximum amount of the commuting costs (using a means of transport other than common public transport/transport organized by the employer) that can be reimbursed by the employer tax-free will not be indexed
- Finally, it was decided that the maximum amount of the tax credit for dependent children will no longer be indexed. Consequently the credit remains capped at EUR 550 per child
Gifts
- In addition to the freezing of the maximum amount, the tax benefit will be reduced from 45% to 30% as from assessment year 2026
Alimony Payments
Currently, alimony payments are 80% deductible from the net income of the payer. The deductibility will be gradually reduced
- to 70% for alimony payments paid as from 1 January 2025
- further to 60% for alimony payments as from 1 January 2026
- and to 50% for alimony payments from 1 January 2027
The taxability of the alimony payment in hand of the recipient will be reduced in the same way.
In addition, alimony payments paid to a resident taxpayer of a country outside of EEA or Switzerland will no longer be tax deductible for the payer. The recipient will no longer be taxed on the received payments in Belgium.

Tax relief for pensions
- As a result of the increase in tax-free allowances, the tax relief for the highest pensions will be reduced as from assessment year 2027
- The general tax reduction for pensions, where the level of joint taxable income will determine whether a reduction will still apply namely:
- Joint taxable income ≤ EUR 14,800 (basic amount): no change to the phasing-out scheme
- Joint taxable income > EUR 36,535 (basic amount): no tax reduction
- If joint taxable income is between the above limits: linear reduction of the reduction to EUR 0.
Tax reduction unemployment income
- Basic reduction will be reduced to a quarter, while additional and supplementary reductions will be eliminated entirely
- Will be implemented from assessment year 2027 through assessment year 2029
- Reduced basic reduction also disappears from assessment year 2030
- Exception for "real" single parents, basic reduction will be only reduced to half
- Unemployment benefits with company supplement will continue to be treated as "other replacement income" which does allow for the reduction.
- The exception for unemployment benefits with company allowance will be abolished as of tax year 2027 onwards
Marital quotient
Married couples and legal cohabitants filing a joint return can apply the marital quotient. The marital quotient allows that for tax calculation purposes, maximum 30% of the professional income of one partner is transferred to the other partner with an absolute maximum of EUR 13,460 for assessment year 2026 in case one of the partners has no or only very limited professional income.
This favourable regime will be gradually phased out however a distinction will be made between :
- Pensioners (both spouses/legal cohabitants partners who have reached the legal retirement age on 1 January of the assessment year ) : phase out over a longer period, with a complete abolition from assessment year 2046. During this entire period, the 30% rate will be maintained, but the maximum amount will be lowered.
- Other taxpayers: the marital quotient will be halved by assessment year 2030.
From assessment year 2027, the maximum amounts will no longer be indexed.
However, note that the personal tax-free allowance that cannot be completely utilized by one of the partners can still be transferred to the other partner. Hence, the impact of the elimination of the marital quotient remains limited.
