Fundacao Tenis is registered in Brazil. While general charitable donations are not directly deductible for individuals, donations to certain government-approved funds (such as those for children's rights or elderly welfare) may qualify for deductions of up to 6% of your income tax due.

Fundacao Tenis is a Brazilian private foundation (fundação privada) - a non-membership legal entity created by the founder(s) endowing it with assets dedicated to a specific charitable, religious, cultural, educational, scientific, or moral purpose. Foundations are governed under articles 62-69 of the Civil Code and are subject to permanent oversight by the local Ministério Público (public prosecutor's office). Fundações are the second-most common legal form for Brazilian nonprofits. Unlike associações, they have no members and require permanent oversight by the local Ministério Público to ensure the founder's specified purpose continues to be served. It is registered with the Receita Federal under the Cadastro Nacional da Pessoa Jurídica (CNPJ), with CNPJ 05022246/0001-88.

You can verify Fundacao Tenis's legal status in three ways. First, look up the Receita Federal CNPJ record directly: https://solucoes.receita.fazenda.gov.br/Servicos/cnpjreva/Cnpjreva_Solicitacao.asp and enter CNPJ 05022246/0001-88. The result page shows the official razão social, legal form (natureza jurídica), registered address, primary economic activity (CNAE), and current status (ativa / suspensa / baixada). Second, search the Mapa das OSCs maintained by IPEA (https://mapaosc.ipea.gov.br/) using either the name or the CNPJ 05022246000188. Mapa OSC aggregates Receita data plus public-sector partnerships and employment counts for over 800,000 Brazilian civil-society organisations. Third, ask the organisation for its most recent estatuto social (bylaws, registered with the local cartório de registro civil de pessoas jurídicas) and its most recent prestação de contas (annual financial report) - legitimate Brazilian nonprofits will share these on request. If the CNPJ is active, the Mapa OSC record matches, and the estatuto / financial report are available, the organisation is legitimate.

Contact Fundacao Tenis directly for current donation methods. Brazilian charities overwhelmingly use Pix - Brazil's instant central-bank payment system, free for individuals and accepted by every retail bank. Pix payments settle in seconds using the recipient's CPF/CNPJ, email, phone or random key (chave Pix) and are the default donation channel for most Brazilian nonprofits. Other common channels: boleto bancário (printable payment slip), TED / DOC bank transfer to the organisation's conta corrente, PicPay, Mercado Pago, PagSeguro, and credit card via Brazilian fundraising platforms such as Vakinha, Benfeitoria, Catarse, Kickante, and Sympla. International donors can give via PayPal, GoFundMe, or international wire transfer (SWIFT). For tax-deductible giving under IRPF (income tax), donations must be channelled through specific funds - FUMCAD / Fundo da Criança e do Adolescente, Fundo do Idoso, and incentive laws for culture (Lei Rouanet), sports (Lei de Incentivo ao Esporte) and health (Pronon, Pronas/PCD); donations to most other charities are NOT deductible from Brazilian income tax. Always confirm the recipient's CNPJ and current Receita status before sending funds.
