Taxation 2026 — What changes, what stays… and what disappears
By Kadir Duran / Bruxelles Korner
8 November 2025

The Arizona government has locked down nearly all tax advantages for the next five years. After a brief period of indexation under the Vivaldi coalition, Finance Minister Jan Jambon has once again frozen fiscal ceilings from 2025 to 2030 and is even scrapping several schemes deemed “inefficient.”

Bottom line:
If you want to lower your 2026 tax bill, you need to act before 31 December 2025, and you need to know which amounts will remain frozen until 2030.

✅ What is frozen until 2030

Most tax ceilings stay locked at their 2024 levels. Key examples:

Pension Savings

Two systems remain:

30% tax reduction up to €1,050 (max €315)
25% tax reduction between €1,050–€1,350 (max €337.50)

The classic trap remains:
A payment between €1,051 and €1,259 gives a smaller tax benefit than staying at €1,050

Smart move:
Stay at €1,050 or go straight to €1,260–€1,350.
From 2026 onwards, the ceilings are frozen. A merger of the two systems is being considered, but nothing is confirmed.

Long-Term Savings (life insurance)

Ceiling frozen at €2,450
Max tax benefit: €735 (30%)
Without the freeze, it would have risen to €2,530

Interest on Savings Accounts

Exemption maintained at €1,020
Beyond that → 15% withholding tax

Service Vouchers (Titres-services)

Highly regional differences:

Wallonia

Price: €10.40 → €11.40 → €12.40
Tax reduction: €0.90 on first 150 vouchers
Max benefit: €135 (or €270 for couples)

Brussels

Price: €10.20
Tax reduction: 15% on 172 vouchers
Max benefit: €263.16 (or €526.32 for couples)

Flanders

Price: €10 / €11
No tax reduction since 2025

ALE / Local Employment Cheques

Ceiling: €1,850

Wallonia: 30% reduction (max €555)
Brussels: 15% (max €277.50)
Flanders: No reduction

Childcare Expenses

Tax reduction: 45% up to €16.90 per day
Net gain: €7.60/day/child
Single parents: up to 75% depending on income

Donations

The Arizona government cuts the deduction:

Before: 45%
Now: 30%

A €40 donation now yields €12 in tax benefit (vs €18 previously).

Roof insulation (Wallonia only)

Reduction: 30%
Ceiling: €4,020
Conditions: building 5+ years old; contractor required; minimum insulation standards

CPTI (Supplementary pension for self-employed individuals)

Reduction: 30% (+ municipal surcharge)
Example: €1,000 contribution → €300 tax benefit
Must respect the 80% rule (combined pension limits)

Renovation of a dwelling rented through an AIS (Wallonia)

Minimum investment: €14,610
Mandatory AIS rental: 9 years
Tax reduction: 5% per year, max €1,510/year
(No advantage in Flanders since 2019; none in Brussels since 2016)

❌ What disappears completely

The federal government is eliminating several tax reductions considered “too costly” or rarely used:

Tax reduction for household employees → abolished
Tax reduction for adoption expenses → removed
Tax reduction for legal expenses insurance → scrapped
Reduction for light electric vehicles (tricycles, quadricycles) → gone
Reduction for capital losses in PRICAF private entities → eliminated

In short: a fiscal system under anesthesia

The federal budget clearly bets on stability — or rather, rigidity.

Taxpayers now face:
✅ multi-year frozen ceilings
✅ widening regional discrepancies
✅ several abolished deductions
✅ and one remaining lever: optimising tax-deductible expenses before 31 December 2025

Belgium is not raising taxes…
But it is quietly reducing almost every way to lower them.
