Calling someone a contractor does not make the relationship independent. If a person works in your team every week, follows a manager's priorities, uses company systems and is paid for an ongoing process, the facts can point to employment even when the document says “service agreement”. The reverse mistake also happens: a business adds employee-style timekeeping and approvals to a genuinely independent project and creates obligations it did not plan for.
In my 15+ years in Estonian accounting, I have found that the safest starting point is the working model, not the hoped-for tax result. The official Tööelu comparison separates employment, authorisation and result-based service contracts by control, personal performance and the result expected. This guide turns those distinctions into a decision a founder can make before access is granted or work begins.
The working reality matters more than the contract label
An employment relationship is characterised by subordination to the employer's management and control. Practical signals include a company-set schedule, a fixed workplace or mandatory online presence, detailed instructions on how the work is done, recurring monthly remuneration, company tools and integration into the organisation. No single signal decides the case; the relationship is assessed as a whole.
The Tööelu service-contract guidance explains the consequence of an unclear mixed relationship: where the facts resemble both employment and another contract, the customer may need to prove that the parties truly agreed to independent services. A heading, invoice template or clause saying “not an employee” cannot replace evidence of real autonomy.
Start by writing down who controls the time, place and method of work; whether the person may use substitutes; whether payment is for time or an accepted result; and whether the relationship is intended to continue. Those answers usually reveal the right legal form faster than editing a contract template.
Three contract models solve different business needs
Estonian practice distinguishes an employment contract from two common agreements under the Law of Obligations Act. An authorisation agreement is suitable when an independent specialist provides a service and decides substantially how and when to perform it. A contract for services is aimed at a specific result that can be delivered and accepted.
The difference is operational. A monthly marketing coordinator working inside the company's planning cycle is not the same arrangement as an external trainer choosing the content of one seminar or a developer delivering a specified migration by an agreed date. The contract should describe that difference rather than force all three into the word “freelancer”.
| Question | Employment contract | Authorisation agreement | Contract for services |
|---|---|---|---|
| What is purchased? | Ongoing work process | Autonomous professional service | Defined result or completed work |
| Who directs the method? | Employer | Service provider | Contractor within agreed specifications |
| Is personal performance central? | Normally yes | Usually agreed for the specialist | Subcontracting may be possible unless restricted |
| Typical end point | Continues until lawfully ended | Mandate completed or agreement terminated | Result delivered and accepted |
| Statutory employee rights | Minimum wage, paid leave, working-time protection | Not automatically | Not automatically |
A service agreement is not a shortcut around payroll taxes
When an Estonian company pays a natural person directly, remuneration under an employment contract and fees under service agreements both fall within employment-income rules. The EMTA employment-income guidance says the payer must account for the applicable income tax, social tax and, in most cases, unemployment insurance and funded-pension contributions. The exact payment type and contributions depend on the recipient and agreement, so payroll setup still matters.
The person must also be entered under the correct type in the employment register before work starts; EMTA lists separate registration types for employment and Law of Obligations Act agreements in its registration instructions. Form TSD and the related payment are due by the 10th day of the month after the fee is paid. A late contract signed after the first working day does not repair a missing or incorrect registration history.
For 2026, EMTA publishes a 22% withholding income-tax rate, 33% social tax, unemployment-insurance rates of 1.6% for the individual and 0.8% for the payer, and funded-pension rates of 2%, 4% or 6% where applicable. The employment contract also carries the statutory minimum wage and leave obligations. If the supplier is a genuine company or sole proprietor issuing an invoice, the analysis changes; do not treat a natural person's service fee as that supplier invoice without checking the legal and tax status.
Three scenarios show where the line usually falls
First, an Estonian company hires a customer-support coordinator for four days a week. The manager sets shifts, provides the account, reviews daily work and expects the person to remain in the role. Even if the person prefers to send a monthly invoice, the operating model points strongly to an employment contract.
Second, a specialist is engaged to deliver one management workshop. The company agrees the audience and date, but the specialist chooses the programme and teaching method and is not part of internal reporting. An authorisation agreement can reflect that autonomous professional service.
Third, a developer undertakes to migrate a defined set of data, meet written acceptance criteria and deliver by 30 September. The company controls the required outcome and security rules but not the developer's daily schedule or method. A result-based contract for services can fit, provided the real working arrangement remains independent.
| Scenario | Decisive fact | Likely starting point |
|---|---|---|
| Recurring support role | Company directs time and daily process | Employment contract |
| Independent workshop | Specialist controls service content and method | Authorisation agreement |
| Data migration project | Measurable result is delivered and accepted | Contract for services |
Make the written contract follow the operating model
Before the start date, align the contract, employment-register entry, payroll code, access rights and manager's instructions. For employment, record the working conditions, pay, workload, place of work and other required information. For an independent service, define the scope, deliverable or mandate, acceptance, fee, expenses, confidentiality, intellectual property and termination without copying employee controls into the agreement.
Revisit the choice when the assignment changes. A three-week project can become an ongoing controlled role; an employee may also take on a genuinely separate one-off mandate. Document why the arrangement changed and update registration and payroll from the correct date instead of waiting for year-end.
For cross-border work, board-member duties or a service provider operating through another company, residence, social-security and permanent-establishment questions can change the answer. Those cases need a separate tax and legal review rather than a clause copied from a domestic template.
The most expensive mistake is to design a service contract and then manage the person exactly like an employee. If the company needs fixed availability, daily supervision and a continuing personal role, I recommend budgeting and registering employment from the start. A cleaner document cannot offset a contradictory working routine.
The reliable decision is not employee versus contractor as a label. It is controlled ongoing work versus an autonomous service or accepted result. Define the operating model, choose the matching agreement, register the correct type and connect payroll to the actual recipient before the first working day.
