Your expenses reduce IVA and IRS. FIZ works out the deductions.

It reduces the IVA payable in the quarterly declaration. If it exceeds the IVA on sales, the excess is carried forward as an IVA credit to later periods. You can request a cash refund of this credit in the declaration when it exceeds 3,000 €, when it stays above 250 € for 12 months, or when you stop trading or switch to the IVA exemption (from 25 €).

An IVA deduction applies to the IVA on business purchases and goes into the quarterly IVA declaration. Personal IRS deductions, such as health and education, reduce income tax in the annual declaration. The two have different rules and limits.

They are rules for different taxes. Under the simplified IRS regime, tax is charged only on a share of what you invoice, set by law: for example, 75% for professional services. With the Article 53 IVA exemption, you do not charge IVA on sales. You can be in the simplified IRS regime and the normal IVA regime at the same time, with periodic declarations and IVA deductions.

Business invoices on e‑Fatura, the rent for your business premises and the salaries you pay, plus a fixed amount the law already allows for, or your Seg. Social contributions if they are higher. The rule applies to services with a 75% or 35% coefficient: together, these expenses must reach 15% of what you invoice for those services.

If the total is below 15%, the difference is added to your taxable income. In the tax reserve, FIZ adds the fixed amount to your business invoices from e‑Fatura and shows how much is left to reach 15%.

By the end of February of the following year; if that day falls on a weekend, the deadline moves to the next working day. Until you say whether an invoice is for your business, it stays pending in e‑Fatura and counts neither for personal IRS deductions nor for business expenses under the 15% rule. FIZ sends the expense type to e‑Fatura as soon as you confirm it.

A valid invoice with your NIF and the required details. The bank record shows the payment, and the invoice is the document that gives the right to deduct.

For example, an invoice from a foreign supplier. Forward it to the @fiz.co address FIZ gives you or upload it as PDF, PNG or JPG. In the normal IVA regime, FIZ includes it in the IVA declaration.

Passenger cars, fuel, meals, accommodation and hospitality expenses are excluded or partly deductible. For example, IVA on diesel for a passenger car is 50% deductible.

In the declaration for the quarter when you receive the invoice or a later one, within 4 years. Under the IVA de caixa regime, where IVA follows payments rather than invoices, the date you pay the invoice counts.

Based on the category, FIZ applies the share of IVA the law allows you to deduct for that type of expense, for example 50% for diesel for a passenger car. For personal expenses, the e‑Fatura category, such as health or education, sets the IRS deduction.

Health expenses with 6% IVA or exempt from IVA, and purchases at 23% with a medical prescription. The part you paid counts, without the amount reimbursed by the SNS or insurance. The health limit is 1,000 € a year per household, within the overall limits.

With the Article 53 exemption, you do not charge IVA on sales, and the IVA on purchases stays a cost, with no deduction. For services bought from foreign suppliers under autoliquidação (the buyer declares the IVA instead of the supplier), the IVA is declared and paid in Portugal, with no deduction. Goods bought in other EU countries follow their own rules, linked to the yearly purchase amount.

Yes, under the simplified IRS regime. FIZ prepares the quarterly Seg. Social declaration and, under the normal IVA regime, the quarterly IVA declaration, and submits them with one click from you. The annual IRS declaration is a separate service: FIZ submits it when you confirm it by paying for the service. With contabilidade organizada (full accounts kept by a certified accountant), that accountant handles the declarations.
