Lawyers, dietitians, psychologists, architects, engineers, translators — very different professions, but the same accounting and tax framework applies to all of them: self-employed professional status. This guide brings together the core obligations that come with that status, and the mistakes we see most often.

## Who Counts as a Self-Employed Professional?

Activity based primarily on personal expertise, knowledge and effort rather than capital, carried out independently rather than under an employer, is classified as self-employment. Lawyers, dietitians, psychologists, architects, engineers, translators, doctors and accountants are typical examples. These professions can be practiced directly as a self-employed professional — with a tax registration certificate — rather than through a sole proprietorship structure.

## When Should a Self-Employment Receipt Be Issued?

Self-employment income is recognized on a cash basis — income arises not when you provide the service, but when you actually collect payment, and a self-employment receipt is issued and the income declared at that point. This differs from the accrual logic behind standard invoicing, and it offers a real cash-flow planning advantage: you don't owe tax on money you haven't received yet.

## How Does Withholding Work?

When a self-employed professional issues a receipt for services provided to a company (or to certain individuals), the payer withholds income tax at a set rate when making the payment, and remits it to the tax office. The self-employed professional then credits this withheld amount against the tax calculated on their annual income tax return. For services provided directly to end consumers, no withholding applies — the full amount, including VAT, is collected.

## VAT Obligations

VAT is calculated separately on the service fee shown on a self-employment receipt and declared through periodic VAT returns. Some self-employed activities may qualify for VAT exemptions — for example, certain healthcare services — and this needs to be assessed based on the specific activity.

## Deductible Expenses for Self-Employed Professionals

- Office/practice rent, electricity, internet and phone costs
- Professional liability insurance and chamber/association membership dues
- Professional publications, conferences, seminars and certification costs
- The documented portion of work-related vehicle and travel expenses

## Common Mistakes

- Recording income as soon as a contract is signed, before payment is actually collected
- Forgetting to credit withheld tax against the annual return, effectively paying tax twice on the same income
- Deducting personal and professional expenses together without separating them
