What the copyright regime still allows
When you create a work and transfer or license the rights attached to it, the amount you receive is not ordinary pay. The Belgian tax authorities treat it as investment income, taxed at 15 % after a flat rate expense deduction, while your usual fees go through the progressive brackets and carry social security contributions.
The gap is wide, which is exactly why the conditions were tightened on 1 January 2023. The regime has not disappeared, but it now targets a specific profile: someone who genuinely produces a protected work and transfers the rights in writing, not someone relabelling part of their fees.
-
Separate taxation at 15 % on the part qualifying as investment income.
-
Flat rate expenses deducted before tax, with no receipts to produce.
-
Withholding tax deducted at source by whoever pays you, when they are established in Belgium.
-
No self employed social security contributions as long as the income keeps its investment classification.
Everything turns on the transfer of rights. Without a written contract identifying the work and transferring rights, there is no copyright income, only an invoice for services.
The access conditions since the reform
The law sets two conditions that must both be met, and the second one is what sinks most hastily built arrangements. First there must be a protected literary or artistic work, or the performance of a performing artist. Then you must transfer or license those rights so that they can be exploited.
That exploitation can be proven in two ways. Either you hold an arts work certificate issued by the competent commission, or you transfer your rights to a third party for communication to the public, public performance or reproduction. An internal document read by three colleagues meets neither test.
-
An original work carrying the personal stamp of its author. A standard dashboard or a copied checklist does not pass that test.
-
A written, dated transfer or licence, describing the work and the scope of the rights.
-
Genuine exploitation by the recipient, or an arts work certificate in hand.
-
A defensible split between the service part and the rights part, quantified in the contract or in an annex.
The tax office looks at the substance, not the label. A contract allocating 30 % to copyright while the work delivered is a plain service will be reclassified, with late payment interest on top.
The 2026 caps: three limits that apply together
Many freelancers only know the absolute cap and get caught out by the other two. All three apply at the same time, and the tightest one wins.
The legal amounts are base figures, indexed every year. The absolute cap starts at 37 500 € and the expense brackets at 10 000 € and 20 000 €. After indexation the cap sits well above 70 000 € and the first expense bracket hovers around 20 000 €. Take the exact figure for the year from the tax authority tables, because it moves every assessment year.
The three limits of the regime at a glance
| Limit |
What the rule says |
What happens if you exceed it |
| Absolute annual cap |
37 500 € base amount, indexed every year, well above 70 000 € today |
The excess becomes professional income, taxed progressively and subject to contributions |
| Flat rate expenses, first bracket |
50 % expenses on the first bracket, around 20 000 € after indexation |
Above that, the expense rate drops |
| Flat rate expenses, second bracket |
25 % expenses on the next bracket, up to roughly 40 000 € |
No flat rate above that, only actual documented expenses |
| Ratio to total pay |
Copyright income cannot exceed 30 % of total pay plus rights from the same client |
The excess is reclassified as remuneration |
| Average of the four previous years |
The average copyright income over the four previous taxable periods cannot exceed the absolute cap |
The regime no longer applies for the current year |
The 30 % limit is measured on everything the same client pays you. Invoice 50 000 € to one client and at most 15 000 € can qualify as copyright income, even if your annual cap is nowhere near being reached.
What it actually leaves you
Nothing beats a figure. Take a freelancer who receives 20 000 € of copyright income over the year, on top of the usual fees, and who stays within the three limits.
Half of that 20 000 € is absorbed by flat rate expenses. Only 10 000 € remains taxable, at 15 %, so 1 500 € of tax. The same 20 000 € earned as fees, for someone already taxed at 45 %, leaves noticeably less once social security contributions of more than 20 % are added to the tax bill.
Worked example: 20 000 € of copyright income in a year

The figures in the table use rounded indexed brackets to show the mechanics. Your accountant will apply the official numbers for the income year concerned.
In practice
Keep fees and rights apart, right on the invoice
The calculation fits on one line of a spreadsheet. The awkward part is the invoice: put the work and the transfer of rights on the same item and an inspection will come back to it. Novadesko keeps the two lines separate and sends the invoice in structured format.
Fourteen days free, no card needed.
Developers and IT: the door closed on code
This is the sore point, and it is better heard plainly. Computer programs are protected under a separate part of the Belgian economic law code, and the 2023 reform reserved the tax regime for literary and artistic works. In practice, source code, an application, an automation script or a business module no longer qualify.
The sector challenged the change, the Constitutional Court dismissed those appeals in 2024, and the exclusion still stands. Developers who used the regime up to 2022 got one transitional year with the caps halved, after which the measure lapsed.
That does not mean nobody in IT can claim it any more. A developer who writes a technical book, records a video course, publishes in depth articles or designs a visual identity is indeed creating a literary or graphic work. What matters is the nature of what you deliver, not the activity code of your company.
What still qualifies when you work in IT
| What you deliver |
Copyright income possible |
Why |
| Source code, application, script, module |
No |
A computer program falls under a separate part of the economic law code, left out of the regime since 2023 |
| Technical documentation, white paper, in depth article |
Yes, under conditions |
An original literary work, if the rights are transferred in writing and it is genuinely published |
| Recorded course, video capsule, podcast |
Yes, under conditions |
A work that reaches an audience, with a publisher or platform as the recipient of the rights |
| Interface design, illustration, brand identity |
Yes, under conditions |
A protected graphic work, with a transfer described in the contract |
| Analysis, advice and support billed by the hour |
No |
You are selling time, not a work whose rights you transfer |
If you were using this regime before 2023 and nothing in your contracts changed, have the arrangement reviewed. A correction spread over several assessment years costs far more than advice taken up front.
Three situations you actually meet
The first is a freelancer building a platform for a Brussels client. Everything invoiced is development work. Not a single euro of copyright income is possible in 2026, however the contract is drafted.
The second is a consultant advising small companies who also produces a series of video courses distributed by a publisher. The course part can fall under the regime: the work exists, it is transferred to a third party and it genuinely reaches an audience. The consulting assignment stays an ordinary service.
The third is a freelance graphic designer delivering brand identities and interface designs. She transfers exploitation rights over protected graphic works, under a contract that describes them. The regime applies, within the 30 % limit on what each client pays her.
What the solid files have in common: an invoice that clearly separates the service line from the transfer of rights line, and a contract that explains why.
Contract, form 281.45 and your tax return
Whoever pays you copyright income has precise obligations. They withhold 15 % on the amount net of flat rate expenses, pay it over to the Treasury and issue a form 281.45 in your name. So you receive an official document showing the gross amount, the expenses deducted and the tax withheld.
That withholding settles the tax for a private individual, but the income still has to appear in your personal income tax return, under investment income. If your client is established abroad, nobody withholds anything for you: declaring the amount and paying the tax is on you.
-
A transfer agreement signed before payment, never reconstructed afterwards.
-
An invoice or statement that isolates the copyright part from the rest.
-
Form 281.45 kept with your accounting records for the year.
-
The amounts reported in your return, even when the tax has already been withheld.
Keep proof of exploitation too: the link to the publication, the print run, the distribution platform. That is what shows communication to the public the day an inspector asks.
Keeping the two kinds of income apart in your books
A copyright file is won or lost on the paperwork. Two years later you still need to find which invoice covered which transfer, for which client and for which work. A spreadsheet living on a laptop will not do that.
In Novadesko you invoice the service and the transfer of rights on separate lines, each with its own description, and the agreement stays attached to the client record. Since 2026 the structured electronic invoice has been mandatory between Belgian companies: your invoices travel over the Peppol network, land straight in the client software and keep that split readable on both sides.
-
Separate invoice lines for fees and for the transfer of rights, with clear wording.
-
Sending and receiving invoices in structured format over Peppol.
-
Contracts and 281.45 forms filed in the client record.
-
A full export to your accountant when the return is due.
The more visible the split is on the invoice itself, the less you will have to explain your arrangement after the fact.
Frequently asked questions
Does the copyright income regime still exist in Belgium in 2026?
Yes. The tax regime for copyright income is still in force: separate taxation at 15 % after flat rate expenses, within an indexed annual cap. What changed on 1 January 2023 were the access conditions, which now require a protected literary or artistic work and a genuine transfer of rights.
What is the copyright income cap in Belgium for 2026?
The legal cap is a base amount of 37 500 €, indexed every year, which has pushed it above 70 000 € in recent years. Two further limits apply: copyright income cannot exceed 30 % of total pay plus rights from the same client, and the average over the four previous years cannot exceed the absolute cap.
Can a software developer still declare copyright income?
Not for code. Computer programs have been excluded since 2023, an exclusion confirmed by the Constitutional Court in 2024. A developer who writes a technical book, produces a video course or creates graphic works can still fall under the regime for those creations, provided the rights are transferred in writing and the work is genuinely exploited.
How is tax on copyright income calculated?
Flat rate expenses are deducted from the gross amount first: 50 % on the first indexed bracket, 25 % on the next one. The balance is taxed at 15 % as investment income. On 20 000 € gross, around 10 000 € remains taxable, which comes to 1 500 € of tax.
Do you pay social security contributions on copyright income?
As long as the income keeps its investment classification and stays within the caps, it is not part of the base used for self employed social security contributions. As soon as part of it is reclassified as professional income, it joins that year's income and feeds the contribution base, on top of progressive taxation.
Who withholds the 15 % tax?
The Belgian payer, meaning the company or publisher paying you. They withhold the tax, pay it over to the administration and give you a form 281.45. If your client is established abroad, nothing is withheld and you have to report the amount yourself in your personal income tax return.
What is the risk if the split is considered excessive?
The part deemed excessive is reclassified as remuneration or profit. It then goes through the progressive brackets, carries social security contributions, and a tax increase plus late payment interest may follow. That is why a cautious split backed by a solid contract beats an ambitious percentage you cannot defend.
How do you prove a transfer of rights during an audit?
With three items: a written agreement signed before payment describing the work and the scope of the rights, an invoice that isolates the transfer line, and evidence of real exploitation such as a link to the publication or a copy of the book. The chronology counts as much as the content.
