On August 3, thousands of Brazilian businesses began issuing invoices showing the new IBS and CBS taxes. Landlords were not included — yet. Their date is December 1, 2026, and there are fewer than four months left.
What happened
Joint Act RFB/CGIBS No. 4 of July 30, 2026, published in the Diário Oficial da União on July 31 (Edition 143, Section 1, page 25), set the official schedule for mandatory electronic invoicing with IBS and CBS.
Article 1, item III, subparagraph (g) is the one that matters to anyone with rental property:
"(g) for leases of movable property and for leases, onerous assignments, and rentals of real property, except for the supplies referred to in subparagraph (d): December 1, 2026"
And item XVIII, for sales:
"XVIII — Electronic Invoice for the Sale of Real Property (NF-e ABI), model 77: December 1, 2026."
For businesses electing Simples Nacional, Brazil's simplified regime for small companies, § 1 postpones everything to January 1, 2027.
The technical read
The first thing to understand is that 2026 is a year of documentary obligation, not payment. This year's test rates — IBS at 0.1% (Article 343 of LC 214/2025) and CBS at 0.9% (Article 346) — come with an express waiver. Article 348, § 1 of the same law provides:
"Payment of IBS and CBS relating to taxable events occurring in the period indicated in the caput is waived for taxpayers who comply with the ancillary obligations set forth in the legislation."
The reading is direct: issue the invoice correctly and you owe nothing in 2026. Fail to issue it and you lose the waiver. It is a rehearsal with consequences.
The second is that the NFS-e has no single date. Joint Act No. 4 split item III into eight subparagraphs across two dates: services generally subject to municipal ISS begin October 1, 2026 (subparagraph d); real property rentals, condominium fees, intangibles, and everything else begin December 1. Confusing the two is an easy mistake and an expensive one.
The third is operational, and it is where the deadline bites. Issuing rental invoices requires registration in the national environment, adaptation of billing systems, a decision about who issues when a property manager is involved, and revision of lease agreements — which typically say nothing about invoicing, because they never needed to. Four months is enough for anyone starting now, and tight for anyone starting in October.
One clarification. Several analyses published in July reported that the obligation for rentals began August 1 or August 3, 2026. That is not what Joint Act No. 4 says. The August 3 dates apply to NF-e, NFC-e, CT-e, BP-e, and MDF-e. Real property rentals are December 1.
If you are a non-resident landlord, this reaches you through your Brazilian tax registration. Brazil does not exempt foreign owners from these obligations; it requires them to be met through a Brazilian tax identification number (CPF or CNPJ) and, in practice, a resident attorney-in-fact holding a power of attorney. If your Brazilian rental income is collected by a property manager, the question of who issues the invoice needs to be settled in writing before December.
Who this affects
- Family holding companies earning rental income
- Individuals classified as regular-regime taxpayers — which requires, cumulatively, rental income above R$ 240,000 in the prior year and more than three distinct properties (Article 251, § 1, I of LC 214/2025)
- Anyone leasing commercial property to a business that will need the input credit
- Condominium associations, as to their fees, also December 1
- Anyone planning to sell property from December onward, under the new NF-e ABI
- Non-resident owners of Brazilian rental property
What to do, and by when
- Determine whether you are a regular-regime taxpayer. An individual qualifies only by meeting both tests in Article 251, § 1, I — income and property count. Fail either one and you are outside.
- Note the anti-fragmentation rule. Article 251, § 2, II provides that if rental income exceeds the threshold by 20%, the individual becomes a taxpayer in the current year, not merely the following one.
- Register for NFS-e issuance and test the workflow before December, not during it.
- Revise lease agreements, specifying who issues the document, within what deadline, and how the rent responds to the tax.
- Align with the property manager, if there is one. Responsibility for issuance needs to be in writing.
The cost of doing nothing
Losing the payment waiver of Article 348, § 1 by failing to meet an ancillary obligation — and entering 2027, when the tax becomes genuinely payable, with an untested system.
Background for readers outside Brazil
Four things make the rest of this document legible.
ITCMD is Brazil's inheritance and gift tax. It is a state tax, not a federal one — each of Brazil's 26 states and the Federal District sets its own rate and rules, within a federal ceiling currently fixed at 8% by the Senate. There is no lifetime exemption comparable to the U.S. federal estate tax exclusion. The tax falls on the recipient, not the estate.
Brazil is in the middle of the largest tax overhaul in its modern history. Constitutional Amendment 132/2023 replaced five consumption taxes with two value-added taxes — IBS (state and municipal) and CBS (federal). The transition runs from 2026 through 2033. 2026 is a test year: invoices must carry the new taxes, but the tax itself is generally not collected.
Two Complementary Laws govern all of this. Lei Complementar 214/2025 created the IBS and CBS. Lei Complementar 227/2026, enacted January 13, 2026 and published January 14, 2026, created the national rules for ITCMD and amended parts of LC 214/2025. A Complementary Law sets binding national standards; states then legislate within them.
A holding familiar is a Brazilian holding company — usually a sociedade limitada, the closest analogue to a U.S. LLC — used to hold family real estate and operating businesses and to organize succession. Its ownership units are called quotas. It is the single most common estate-planning vehicle in Brazil, and three of the five pieces below concern it directly.

Verification record
All provisions were verified against the official text published by the Presidency of Brazil and the Diário Oficial da União on August 6, 2026. Verification corrected six statements circulating in secondary analyses:
- LC 227/2026 was enacted January 13, 2026 and published January 14, 2026 (republished January 15, corrected January 23).
- The gift aggregation rule is in Article 155, not Article 157, which addresses taxpayers.
- Mandatory electronic invoicing for real property rentals is December 1, 2026, not August 1 or 3, 2026.
- CBS does not reach its full rate in 2027: Article 347 of LC 214/2025 provides a 0.1 percentage point reduction for 2027–2028.
- 26.5% is not a rate — it is a review trigger under Article 475, § 11. Reference rates will be fixed by Senate resolution under Article 349.
- Residential rentals of up to 90 days carry a 40% reduction, not 70%, and lose the social reducer (Articles 253 and 281, against 260 and 261).
State caveat: progressive ITCMD rates depend on state legislation. São Paulo still applies the flat 4% rate of State Law 10.705/2000, with a bill pending to introduce progressivity.
