Possible tax on Brazil’s tax-exempt bonds divides investors
Brazil is again debating taxes on tax-exempt investments as the next government looks for ways to reduce the budget deficit.
The debate includes infrastructure debentures, bonds used to help finance long-term projects, which currently offer tax advantages to investors.
Some fund managers say reduced tax exemptions could make bonds already issued more attractive, while others warn that taxing the bonds could weaken project financing.
The market is substantial: the outstanding value of these bonds is R$571 billion, and infrastructure funds hold R$346.5 billion in assets.
A similar proposal in 2025 would have taxed new issues, but it expired after being withdrawn from the lower house’s agenda; investors then rushed to buy bonds, and average spreads fell by 0.60 percentage points.
No final tax decision is described, and managers say the impact would depend on which investments were taxed and whether the rules applied to existing bonds.
A renewed debate over taxing Brazil’s tax-exempt investments has divided fund managers over the impact on infrastructure debentures.
Some managers say reduced tax exemptions could make already-issued bonds more valuable and attractive to investors.
Others warn that ending the exemption could weaken financing for long-term infrastructure projects.
Riza Asset puts the stock of incentivized debentures at R$571 billion this year and infrastructure funds’ assets at R$346.5 billion.

Market impact
Managers who see an opportunity
Reduced exemptions could make existing infrastructure debentures more attractive and support their performance.
Managers who warn of harm
Ending the exemption could undermine a key selling point for the bonds and funds.
Infrastructure funding
Managers who see an opportunity
Infrastructure debentures could benefit if taxes apply only to shorter-term tax-exempt bank bonds.
Managers who warn of harm
Investors could shift away from infrastructure bonds and funds, weakening financing for projects.
Provisional Measure 1,303 was issued, proposing a 5% income tax on returns from new issues of incentivized bonds.
The measure expired after being removed from the Chamber of Deputies’ agenda.
Discussion of possible taxes on exempt investments returned earlier than Ricardo Ara had expected.

What people are saying
There is a lot being said about creating an IOF tax on exempt assets or imposing a tax, but it is not known whether this would apply to the primary market or also to the secondary market.
In our view, this trend, combined with the valuation of infrastructure debentures, makes this segment the most attractive part of the credit market right now.
If money stops flowing into debentures and infrastructure funds, the consequence for the country will be drastic if other channels do not emerge.
The exemption always adds a few percentage points to the investor’s yield compared with NTN-Bs.
