Copyright Income Tax 2026: IT Freelancers Are Back In, but the Deal Is Different

If you are a software developer working through a Belgian company — or invoicing as a self-employed dev — copyright tax just came back into your life. Here is the version you actually need.

What just changed

For three years (2023, 2024, 2025), you were not allowed to use the favourable copyright tax regime. You earned a salary or a self-employed fee, you paid full Belgian income tax on it. The Constitutional Court dismissed the challenge to that exclusion in 2024, so there is nothing to reclaim for those years.

From 1 January 2026, the regime is back for software. You can route up to 30% of your remuneration through copyright. The effective tax on that 30% is around 15–16%. The remaining 70% you pay normally.

The annual ceiling is €77,220 of copyright income for 2026. Beyond that, it gets reclassified as ordinary income. If you see €75,360 quoted somewhere, that was last year's ceiling — the 2026 figure was only published in August 2026.

The numbers, for a developer paying themselves €150,000

You keep about €18,000 more per year by using the regime. That is a real number, not a marketing number.

If you earn closer to €80,000, the gap is smaller (~€10,000). If you earn closer to €250,000, you hit the €77,220 ceiling on the copyright side — the regime caps out and the advantage flattens.

What used to be better

The "old" regime (pre-2023) allowed a flat 50% cost deduction on the first slice of copyright income. The effective rate was around 7.5% — half of what it is now. Every blog post from 2018–2022 you find online quotes that number. It no longer applies to you unless you hold an artist's certificate, which IT developers do not.

So the regime is back, but it is half as generous as it used to be. Adjust your expectations.

What you actually need to do

1. Talk to your accountant before 30 June 2026 if you want to apply the regime for the full year.
2. Sign a real copyright transfer agreement with your client (or with your own company, if you are a director). The clause must say what code/work is being transferred, when, for what scope.
3. Split your invoices into two lines: services (70%) and copyright transfer (30%). One line, not two invoices.
4. Cap yourself at 30% and €77,220. The 30% is of the total on the engagement — copyright plus the fee for the services — and only the excess gets requalified. Going over is the most common audit trigger.
5. Keep evidence that you are actually creating something. Code reviews, commit logs, design docs, original specs. If you are pure ops or pure project management, the regime does not apply — you are not creating a copyrightable work.

When the regime does not help you

• You are an employee with a flat salary your employer will not restructure. (Most won't.)
• You only do helpdesk, support, or pure ops — no original creative output.
• Your total income is under ~€50,000 — the absolute savings are modest and the administrative cost (separate contracts, fiches 281.45, slight audit risk) may not be worth it.

When it is the most important call of your year

• You are a self-employed senior dev invoicing €100k+.
• You are a founder paying yourself through a BV/SRL — combine this with VVPRbis (see VVPRbis dividends) and you get the lowest legal effective rate available in Belgium.

The one-sentence answer

If you write original code for a living and you earn more than €80,000, set up copyright before the end of June 2026. If not, ignore it.

Legal basis: Articles 17, §1, 5° and 37 CIR/WIB 92 (income from movable property, copyright). Reform vehicle: articles 74 and 75 of the Act of 15 July 2026 reforming personal income tax (Belgisch Staatsblad, 29 July 2026), which take effect on 1 January 2026 and apply to income paid or attributed from that date. No court restored anything: in judgment no. 52/2024 of 16 May 2024 the Constitutional Court dismissed the appeals brought by software developers and IT companies against the 2023 exclusion, holding it reasonably justified. The restoration is purely legislative, and 2023 through 2025 stay closed.

What 1 January 2026 does, mechanically

1. Re-inclusion of IT activities

The 2023 reform amended Art. 17, §1, 5° to require that the transferred copyright relate to a "protected work in the sense of Book XI Title 5 of the Code of Economic Law". Article 100 of that reform put income relating to computer programs outside the regime — even though Book XI Title 6 explicitly protects software — and the Constitutional Court upheld the exclusion in judgment no. 52/2024.

The 2026 amendment adds an explicit reference to software (Book XI Title 6) within the scope of qualifying works. Conditions:

• Real transfer (cession or license) of economic rights to the principal/employer.
• Written transfer agreement specifying the rights transferred, scope, duration.
• Genuine creative contribution (the "originality" test of Infopaq / Painer remains).
• For a rightholder without an arts certificate, a transfer or licence to a third party for communication to the public, public performance or reproduction.

Whether software written for a client's internal use meets that last condition is untested: the Council of State raised the point during the passage of the bill, and there is no case law or published ruling practice on the text as it applies from 2026. The statutory scope is restored; whether a given contract lands inside it remains a question of fact.

2. The 30/70 rule (unchanged structurally, tightened administratively)

Article 37, second paragraph, first indent CIR/WIB 92 requalifies copyright income as professional income to the extent that it exceeds 30% of the total remuneration — the copyright together with the remuneration for the services provided. Only the excess is requalified, not the whole amount. Under the third paragraph the cap applies only where the transfer or licence is accompanied by a service performed; copyright remuneration received later, separately from an initial remuneration that also covered the service, sits outside it. The remaining 70% must qualify and be paid as regular professional income subject to either:

• Wage tax (employee), or
• Withholding on directors' fees, or
• Self-employed taxation.

The transfer agreement must specify the breakdown. The tax authority's audit playbook is to challenge the 30/70 split where there is no clear allocation of working time / creative output.

The transitional percentages of article 551, §1 (50% for assessment year 2024, 40% for assessment year 2025) have expired. For income year 2026 the figure is 30%, with no transitional relief.

3. €77,220 ceiling for income year 2026

The absolute annual ceiling is €77,220 for income year 2026 (assessment year 2027): the €37,500 base amount of article 37 CIR/WIB 92, indexed at the coefficient 2.0592 fixed in the FPS Finance indexation notice for assessment year 2027 (Belgisch Staatsblad, 12 August 2026). The same €77,220 is the first tranche taxed at the separate 15% rate and the first tranche subject to the 15% withholding tax. Every euro above the ceiling is automatically reclassified as professional income — there is no escape via prolongation, deferral, or staggering.

Watch the year label. €75,360 is the assessment year 2026 figure — income year 2025, coefficient 2.0096 — and it is still circulating in commentary written before the AY 2027 notice appeared on 12 August 2026. Quoted too low it costs the client money; quoted too high, the excess comes back requalified.

The four-year average is a second, separate gate. The final limb of article 37, second paragraph conditions the movable-income qualification on the average gross copyright and neighbouring-rights income of the four preceding taxable periods — measured before the 30% and €37,500 limits, excluding where relevant the period in which the activity started — not exceeding the same indexed ceiling. Exceed that average and the income does not keep its movable character at all: it is professional income in full.

4. The cost deduction collapse

This is the silent change.

• Pre-2023: flat deduction of 50% on the first €17,090, 25% on €17,090–€34,170, 0% above (indexed amounts). Effective tax: 15% × 50% = 7.5% on the first slice.
• 2023–2025: flat deductions retained for the (then-narrowed) qualifying population.
• 2026 onwards: the brackets still exist and are indexed — 50% up to €20,590, 25% from €20,590 to €41,180, nothing above, a maximum lump sum of €15,442.50 — but articles 10 to 12 of the Programme Act of 30 May 2026 reserve them for holders of a "Kunstwerkattest" / "Attestation du travail des arts" under article 7 of the Act of 16 December 2022, or of the "plus" certificate of the Royal Decree of 13 March 2023. The "starter" certificate is expressly excluded. Without one, the taxable base is the gross copyright income. The restriction runs from 1 January 2026, except for the withholding tax itself, which follows it only for income paid or attributed from 11 June 2026.

Effective tax rate on copyright income for non-certified taxpayers (i.e., 99% of IT freelancers): 15% movable withholding + crisis contribution + communal additional taxes ≈ 15.5–16% of gross.

This is still significantly below the marginal personal income tax rate (50% + social security + communal). The optimisation is real. But the headline 7.5% rate is gone.

5. Real cost deduction as fallback

Where the taxpayer can substantiate actual costs related to the creation of the work (specialised software licences, hardware, professional training in the creative competence, attributable office overhead), those costs remain deductible against the copyright income. In practice: keep invoices, maintain a separate creative-activity cost ledger, allocate office space on a square-metre basis.

The FOD has signalled tighter audits on real-cost claims that exceed the abolished flat-rate equivalent — i.e., claims significantly above 25–50%.

6. Social security implications

Copyright remuneration remains outside the scope of social security contributions under the conditions of the 2008 / 2024 INASTI–ONSS / RSZ regulations. This was the largest economic advantage of the regime and is preserved. A €100 copyright fee carries no social charge; a €100 director's fee carries ~22% (RSZ employer + employee equivalent for managers under specific assimilation rules) and personal contribution.

This means even with the lost flat deduction, the comparative advantage versus regular remuneration remains 30+ percentage points, depending on activity and structure.

7. Contract & invoicing checklist

For each IT freelancer / consultant client invoking the regime:

1. Master Services Agreement with explicit IP clause: rights transferred, retained, licensed back.
2. Per-engagement statement of work identifying the deliverable as a protected work (code module, design, technical documentation in copyrightable form).
3. Invoice line-item separation: e.g., "Services — €70" and "Cession of copyright — €30" referencing the contract.
4. 30% cap monitored monthly: cumulative copyright over the year cannot exceed 30% of cumulative gross. Re-balance in Q4 if needed.
5. Withholding tax (Pr.M.): 15% withheld by the debtor on the copyright line; declared via the Bedrijfsvoorheffing / Précompte mobilier mechanism. Reported on the 281.45 fiche.
6. Personal tax return: copyright income reported in box VII / Cadre VII; cross-checked against the 281.45.

8. Audit risk markers

• Allocation entirely concentrated on copyright early in the year (suggests retroactive labelling).
• 30% cap reached on a non-creative role (pure ops, pure devops).
• No documented deliverable identifiable as a "work".
• Identical 30/70 split across many engagements without per-deliverable rationale.

Reasonable position: document originality and creative effort per deliverable. The 30% is a ceiling, not a default.
