Brazilian income-tax deductions for self-employed professionals: the 2026 cash ledger

This guide is for a professional who earns income as a self-employed individual in Brazil. A legal entity’s expense follows the company’s accounting records and tax regime; it must not be entered automatically in the owner’s individual income-tax return.

In the Livro Caixa cash ledger, Brazil’s Federal Revenue Service—the Receita Federal—allows expenses that are necessary to earn the income and maintain its productive source, provided they are recorded and supported. Labeling an item “for professional use” does not make every expense deductible.

Who may use the Livro Caixa

A taxpayer who receives non-employment work income may record expenses from the activity. Income received from individuals or from abroad enters the monthly Carnê-Leão system. Someone who provides services only to legal entities may also keep a Livro Caixa and claim permitted expenses in the annual return.

The deductible amount is limited to the activity’s monthly income. An excess may be carried to later months of the same calendar year, but not beyond December.

What may be deductible

When necessary, customary, relevant to the activity, and documented:

• employee compensation and related charges;
• fees directly connected to the activity;
• rent for the professional premises;
• water, electricity, telephone, and consumable supplies;
• payments to third parties that are necessary operating costs;
• registration, publication, accommodation, and other costs of a conference needed for professional specialization, if not reimbursed.

For premises also used as a home, the Receita Federal allows allocation of certain expenses when professional and personal use cannot be separated, subject to its official criteria. Do not apply a percentage based only on floor area without checking the applicable rule.

What does not enter the Livro Caixa

Official guidance excludes, among other items:

• depreciation of premises, machinery, and equipment;
• lease payments;
• transportation and travel, except for the specific rule covering self-employed commercial representatives;
• personal or family expenses;
• treating the purchase of durable assets as an ordinary operating cost;
• an expense reimbursed by the customer.

A laptop, vehicle, or furniture therefore should not be “depreciated in the Livro Caixa” based on generic advice.

The cash ledger is not the list of personal deductions

Healthcare, education, dependants, alimony, and pension contributions follow their own rules in the annual return. A professional course does not automatically qualify as deductible education: the education deduction covers specified levels and forms of education and has an annual limit. PGBL pension-plan contributions may be deductible up to 12% of taxable income under the statutory conditions; VGBL contributions are not deductible.

Medicines purchased separately, non-degree courses, and vehicle costs should not be presented as general deductions without a specific legal basis.

Documents for each entry

• a valid invoice or receipt;
• payer and beneficiary identification;
• payment date and amount;
• description of the service or item;
• proof of payment;
• explanation of the link to the income;
• allocation calculation, when used.

A bank statement may prove payment but does not necessarily prove the nature or necessity of the expense.

Monthly routine

1. Record income on the date received.
2. Enter only paid and supported expenses.
3. Link each document to its business purpose.
4. Separate personal expenses.
5. Check the monthly limit and any carried excess.
6. Calculate Carnê-Leão when due.
7. Reconcile the data before filing the annual return.

Do not mix the individual and the company

If the invoice and contract belong to the company, the income and expense belong in the company’s accounting. If the individual provides the service, apply the self-employed rules. Switching documents according to the preferred tax result creates inconsistencies.

To compare the structures, read how an independent professional can reduce taxes legally. VMAHUB can review the supporting documents and separate Livro Caixa, individual income tax, and company accounting without duplicating deductions.
