With the arrival of 2026, that old question knocks on the door of many professionals: “I've received a bill from the union, do I have to pay it?”. For those who work for themselves (self-employed) or are self-employed (doctors, lawyers, engineers), the short answer is no, But the full answer involves understanding your rights and your career strategy.
Below, I've translated the “legalese” into clear, organized language to help you and your team decide with confidence.
The end of compulsory union tax
Since Labor reform of 2017, the union contribution ceased to be a compulsory tax (that automatic deduction of a day's work) and became optional.
What the law says today:
-
Prior and Express Authorization: The union can only charge you if you authorize it in writing and on an individual basis.
-
Freedom of Choice: You have the constitutional right not to join and not to pay if you feel that the organization does not represent you.
-
STF decision: The Supreme Court has already confirmed that this change is valid. In other words, no one can force you to pay “by force”.
Professional Council vs. Trade Union: don't confuse them!
This is the most common mistake. Many professionals think that because they pay the council of their category, they are in good standing with the union (or vice versa).
Payment due in 2026
For self-employed and freelance professionals who, after strategic analysis, voluntarily choose to pay their union dues, it is essential to observe the official calendar. Traditionally, the deadline for non-employed professionals to pay their union dues is the last working day of February.
Therefore, for the 2026 financial year, the deadline for optional payment will be February 27, 2026.
If payment is made after this deadline, fines and interest may be charged, as stipulated in the respective union's bylaws, as well as monetary corrections. It is recommended that professionals request the payment slip directly on the portal of the union representing their category, ensuring that the destination of the funds is correctly aligned with their professional framework.
When is it worth paying?
Although not obligatory, payment can be seen as a investment and not just a cost. Before tearing up the ticket, check if the union offers it:
-
Negotiating power: Strong unions get better conditions in collective agreements.
-
Direct Benefits: Group health plans, refresher courses, free legal assistance and agreements.
-
Political representation: Defending the category before the government and regulatory bodies.
Compliance Tip: If you are self-employed and provide services to large companies, they may require proof of union compliance in audits to avoid labor risks. Keep an eye on your contracts!

Checklist: I've been billed, now what?
Don't pay the boleto automatically. Follow these four steps:
-
Did I authorize it? Check if you have signed any documents or given your digital consent to the charge.
-
Is this my union? Check that the organization really represents your core business.
-
CPF or CNPJ? Check whether the charge is for you (individual) or your company (legal entity). The amounts and rules change.
-
What's the deadline? For those who choose to pay voluntarily in 2026, the deadline is usually last working day of february (27/02/2026).
Conclusion
In 2026, the golden rule is: The union contribution is a choice, not a tax. Overpayment is a waste of money, but the lack of representation in a strong category can also have long-term costs.
