Incentivized debentures and tax exemption rule
Law 12.431/2011 created the debêntures incentivadas: corporate bonds issued to fund infrastructure projects in Brazil (energy, sanitation, transport, logistics, telecom) once the relevant ministry signs off. What sets them apart is the full income tax exemption (IR) for individuals (PF) resident in Brazil. There's no regressive table (22.5%→15%) and no IOF after 30 days. Maturities usually run 5 to 10 years, and most issues track IPCA+ a spread (say, IPCA + 6.5% a.a.), though a few are prefixed. CRI and CRA (real estate and agribusiness certificates) carry a comparable PF exemption under Law 12.024/2009 and 11.033/2004. Example: a 7% a.a. coupon over 1,080 days for an individual returns ~21.4% gross with zero IR. A CDB at 110% of a 10% CDI would look bigger on paper, but 15% of it goes to IR.
Applications
Individual investors (PF) reach for these when building a tax-efficient fixed-income sleeve. They sit next to LCI/LCA (also IR-exempt, but with shorter terms and FGC coverage up to R$ 250k) as an alternative, and on the issuer side they're a way to raise long-term infrastructure capital where demand tends to be strong. You'll see them often in pension and long-horizon portfolios, since the inflation-linked leg (IPCA+) protects purchasing power.
FAQ
Is the IR exemption only for individuals? Yes. Legal entities (PJ) pay 15% IR on gains. The exemption is reserved for PF residents.
Is there FGC coverage? No. The Credit Guarantee Fund (FGC) does not cover debentures, so the credit risk rests with the issuer. Look at the rating before buying (AAA–A is investment grade).
What about liquidity? You can trade them on B3's secondary market, but the spreads can get wide. If you want predictable returns, plan on holding to maturity.
How does IPCA+ work? The coupon pays inflation (IPCA) plus a real spread, so your purchasing power stays protected for the whole holding period.

Breakeven Tax Rate (Tax-Free vs Taxable)
Computes the breakeven tax rate between a tax-free bond and a taxable one: the rate at which the after-tax return of the two becomes equal, t* = 1 − (tax-free yield / taxable yield). Above that rate, the tax-free bond (like a municipal) pays off more; below it, the taxable one is worth it even after tax. It's the calculation that decides between the two based on your tax bracket. Enter the yields of the tax-free and taxable bonds.

Tesouro Prefixado Bond Yield Calculator
Computes gross yield of a Brazilian Tesouro Prefixado bond from invested amount, annual contracted rate and years to maturity.
Realized Yield with Reinvestment
Computes the realized compound (horizon) yield of a bond held to maturity, taking into account the actual reinvestment rate of the coupons. Unlike YTM, which assumes coupons earn the bond's own rate, this calculation uses the rate you can actually get when reinvesting — hence the concept of reinvestment risk. It adds the future value of reinvested coupons to the principal and returns the annualized yield (BEY and effective annual). Enter the face, the coupon per period, the reinvestment rate, the periods, the purchase price and the periods per year.
LCI/LCA Calculator (no IR)
Simulate LCI (real estate) or LCA (agribusiness): % of CDI, term. Since IR-exempt, net = gross. Compares to equivalent CDB.
