Cuba Tax Filing Guide 2026

Cuba's tax filing system is managed through the Oficina Nacional de Administracion Tributaria (ONAT). Individuals must file annual IIT returns by 30 April, companies by 30 June. Quarterly instalment payments are required for self-employed individuals and companies. All taxpayers must obtain a Tax Identification Number (NIT β€” Numero de Identificacion Tributaria). Penalties apply for late filing and late payment. ONAT has been modernising its systems with online filing options for registered taxpayers.

Overview β€” Tax Filing in Cuba

The Oficina Nacional de Administracion Tributaria (ONAT) administers all tax filing, payment, and compliance in Cuba. Taxpayers register with ONAT, obtain a Tax Identification Number (NIT), and file returns electronically or in person at ONAT offices. The system covers income tax (personal and corporate), Sales and Services Tax, property tax, social security contributions, and other levies. ONAT has been progressively introducing online filing through its portal, though many taxpayers still file paper returns at local ONAT offices. The tax year is the calendar year (January to December) for both individuals and companies.

Tax Identification Number (NIT)

A NIT (Numero de Identificacion Tributaria) is mandatory for all taxpayers in Cuba. Key facts:

  • Individuals use their NIT for all tax matters including filing returns, making payments, and correspondence with ONAT
  • Companies receive a separate corporate NIT upon registration
  • Self-employed individuals must obtain a NIT before starting business activities
  • The NIT is linked to the taxpayer's identity card (Carnet de Identidad) for individuals
  • Foreign investors and expatriates must obtain a NIT through the local ONAT office

Filing Deadlines

Different taxpayers have different filing deadlines in Cuba:

  • Individuals (IIT) β€” annual return by 30 April of the following year
  • Companies (CIT) β€” annual return by 30 June (or within 90 days of year-end for non-calendar year accounts)
  • Self-employed (quarterly) β€” quarterly instalment returns by 20 April, 20 July, 20 October, and 20 January
  • Sales and Services Tax β€” monthly return by the 20th of the following month
  • PAYE (employers) β€” monthly return by the 15th of the following month
  • Property tax β€” annual return by 31 March

Late filing attracts penalties of up to 50% of the tax due, plus monthly interest at the official rate.

Quarterly Instalments for Self-Employed

Self-employed individuals must pay estimated tax in quarterly instalments:

  • Q1 β€” due 20 April (25% of estimated annual tax)
  • Q2 β€” due 20 July (25% of estimated annual tax)
  • Q3 β€” due 20 October (25% of estimated annual tax)
  • Q4 β€” due 20 January (25% of estimated annual tax)

The estimated tax is based on the previous year's liability adjusted for expected changes in income. If the actual tax computed in the annual return exceeds total instalments paid, the balance is due at the time of filing. Overpayments may be refunded or credited against the next year's liability.

Penalties & Enforcement

ONAT has broad enforcement powers under Law 113/2012. Key penalties include:

  • Late filing β€” 10–50% of the tax due depending on the period of delay
  • Late payment β€” monthly interest at the official rate (typically 1–2% per month)
  • Failure to register for tax β€” fines of CUP 5,000–50,000 plus back taxes
  • Tax evasion β€” 100% penalty on evaded tax plus potential criminal prosecution
  • Failure to maintain records β€” fines up to CUP 20,000
  • Non-issuance of tax invoices β€” fines up to CUP 10,000

ONAT may freeze bank accounts, seize assets, and suspend business operations for non-compliance.

FAQs

Can I file my tax return online?

ONAT provides an online portal for registered taxpayers, though the system is still being rolled out. Many taxpayers, particularly in rural areas, still file paper returns at local ONAT offices. Online filing is expected to become mandatory in the coming years.

What records do I need to keep?

Taxpayers must keep records for at least 5 years from the end of the tax year. Records include income statements, receipts, invoices, bank statements, contracts, and asset registers.

How can I get a Tax Clearance Certificate?

A Tax Clearance Certificate (Certificado de Solvencia Fiscal) can be obtained from ONAT if all returns are filed and taxes paid. It is required for many transactions including selling property, obtaining business licences, and leaving the country for extended periods.
