Invoicing for freelancers and consultants

Moving to the standard VAT regime is a major milestone for any consultant or freelancer in Portugal. It means your turnover has gone beyond the exemption thresholds, or that your cost structure makes VAT deduction worthwhile. But with this shift comes greater tax responsibility, and getting your invoicing right becomes critical to avoid penalties from the Autoridade Tributária e Aduaneira (AT).

Managing invoicing under the standard regime isn’t just about meeting tight deadlines. It also requires tools that ensure automatic SAF-T file submission and correct VAT settlement. Moloni ON is the ideal tech partner here, simplifying complex processes so you can focus on what really matters: your work and your professional freedom.

Key Takeaways

• Certified software is mandatory: Under the standard regime, you must use invoicing software certified by the Tax Authority, such as Moloni ON, to issue all sales documents.
• VAT charging and deduction: You must charge VAT on invoices (usually 23%) and can deduct VAT on business expenses, which is a competitive advantage if you have significant costs.
• SAF-T(PT) submission: The SAF-T(PT) file must be sent to the AT by the 5th day of the following month after issuing invoices. Moloni ON automates this for you.
• Withholding tax: If you provide services to companies (legal entities), you must apply IRS withholding tax (usually 25%) when invoicing.
• Tax calendar: Being in the standard regime means submitting periodic VAT returns (monthly or quarterly), requiring stricter accounting discipline.

What changes when you move to the standard VAT regime?

If you were previously exempt under Article 53 of the VAT Code (CIVA), entering the standard regime changes the game completely. The main difference is that you effectively become a tax collector for the State. Every time you invoice a consultancy service, you must add VAT at the applicable rate (23% in mainland Portugal).

But it’s not all obligations. The big upside is tax neutrality. In the standard regime, the VAT you pay on business expenses (computers, software like Moloni ON, office supplies or marketing services) can be recovered. If your costs are significant, this regime can actually be more financially beneficial than exemption.

It also boosts your professional image. Being in the standard regime signals to the market that your turnover is solid (typically above €15,000 per year under current rules) or that you’ve chosen a more transparent and professional financial setup.

How to issue an invoice correctly in Moloni ON

Issuing an invoice is not just entering a value into a digital document. In the standard regime, there are mandatory elements that, if missing, may invalidate the invoice before the AT. With Moloni ON, the invoice structure is already preconfigured to comply with VAT law.

Essential elements include:

1. Party identification: Full name, tax address and taxpayer number (NIF) of both supplier and client.
2. Sequential numbering: Moloni ON ensures there are no gaps in invoice numbering.
3. Issue date and service date: Crucial for tax calculation.
4. Service description: Clear explanation of what was delivered (e.g. “Marketing Strategy Consultancy – April 2026”).
5. Tax base and rates: Clear breakdown of net amount, VAT rate applied, and tax amount.

In Moloni ON, you can set up custom document templates that keep your branding while ensuring all legal fields are filled automatically and without manual errors.

What about withholding tax for freelancers?

This is a classic question. If you’re a freelancer or consultant and your client is a company with organised accounting, you must apply IRS withholding tax on your invoice. This means your client retains a percentage of your payment (usually 25% for Category B income) and pays it directly to the State on your behalf.

In Moloni ON, setting up withholding tax is very straightforward. When creating an invoice, you select the retention rate and the software automatically calculates your net amount.

Keep in mind: if your annual income is below €15,000, you may be exempt, but once you exceed that threshold, withholding becomes mandatory.

How SAF-T communication works and why it matters

The SAF-T(PT) file (Standard Audit File for Tax purposes) is a digital summary of all your invoicing activity. In Portugal, it must be submitted to the Tax Authority by the 5th day of the following month.

Missing this deadline can lead to significant fines. Moloni ON solves this in two ways:

• Manual export: You can download the file and submit it via the Tax Authority portal;
• Automatic submission: You can configure the software to send data directly to the AT via webservice. This is the “smart lazy” option (our favourite), ensuring you never miss a deadline and your data stays fully synced.

Can I deduct expenses as a consultant under the standard regime?

Yes and this is the big win compared to the exemption. Under the standard regime, VAT stops being a cost and becomes a credit.

Imagine you buy a new laptop for €1,000 + VAT (€230). Under the exemption, your real cost is €1,230. Under the standard regime, the €230 VAT is deductible in your VAT return. In practice, the State either refunds it or offsets it against the VAT you collect from clients.

Common deductible expenses for consultants include:

• Office or coworking space rent;
• Software subscriptions (like Moloni ON);
• IT equipment and office furniture;
• Telecom services (internet and business mobile);
• Travel and accommodation (subject to specific limits).

How Moloni ON helps you manage VAT deadlines

Cash flow management is one of the biggest challenges in the standard regime. You receive payments including VAT, but that VAT isn’t yours — you must set it aside for the State.

Moloni ON provides reporting tools that let you see, at any time, how much VAT you’ve charged and how much you’ve deducted. This real-time visibility prevents nasty surprises when your accountant sends you the tax payment slip. Through intuitive dashboards, you can forecast cash flow and ensure you always have liquidity to meet tax obligations without stress.

What are the penalties for invoicing without certified software?

Many freelancers start out using Word or Excel templates. In Portugal, that’s illegal for anyone required to use certified invoicing software. Using non-certified programs can result in heavy fines and may trigger deep tax audits.

Using Moloni ON removes that risk entirely. As cloud-based certified software, it is always up to date with the latest legal changes. If the AT updates rules tomorrow, the software updates automatically. No installations, no extra update fees.

Tips for smooth, professional invoicing

To keep your business organised and maintain a trustworthy image with clients, follow these best practices:

• Invoice immediately after delivering the service: improves cash flow and avoids forgetfulness;
• Automate recurring contracts: if you work on retainers, let Moloni ON generate invoices automatically each month;
• Double-check client details: NIF or address errors mean cancellations and extra admin work;
• Keep expense receipts: to deduct VAT, you need valid invoices with your NIF properly recorded.

Moving to the standard VAT regime and using Moloni ON is a real step up in your career. With the right tools and a clear understanding of your obligations, bureaucracy stops being a burden and becomes just another manageable part of your professional routine.
