Natural persons are regarded to be residents or non-residents for taxation purposes.
Non-residents have a limited tax liability in Estonia, only the Estonian-source income is taxed.
Income tax is withheld upon payment of taxable income. The general income tax rate is the same (20% in 2018) for resident and non-resident persons. Income tax withheld in accordance with the rates specified in the Estonian Income Tax Act or in tax treaties is, for a non-resident recipient, the final income tax on income from Estonian sources.
In Estonia, the tax incentives or exemptions arising from conventions for the avoidance of double taxation (hereinafter tax treaty) can be applied only if the recipient of the payment has certified her or his residence status to the withholding agent. The certificate of residency shall be submitted to a service bureau of the Estonian Tax and Customs Board not later than at the moment of filing the tax return. The document need not be submitted if valid data on the recipient of income and the residency of the recipient of income have been entered in the register of taxable persons.
You may use Form TM 3 for certifying the recipient of income and the residency of the recipient or a relevant form issued by the competent tax authority of your country. The certificates are valid 36 months upon legal persons and 12 months upon natural persons as recipients of income.
In case the income tax on the payments made to the taxpayer has been withheld at higher rate than prescribed in tax treaty, the beneficial owner of the income or his representative has the right to apply to the Estonian tax authority within three years after the due date for payment of the tax for a refund of the overpaid tax amount.
In order to get back the overpaid income tax amount, the application on Form TM 3 for a refund of the Estonian income tax withheld at source has to be submitted to the service bureau of the Estonian Tax and Customs Board in Tallinn (Lõõtsa 8a, 15176 Tallinn, Estonia, e-mail address: firstname.lastname@example.org).
A freeform application will be accepted, but it must include taxpayer's bank account number and information about amounts of payments and tax withheld in Estonia. Upon the refund of overpaid tax to a taxpayer by transferring the amount to the taxpayer’s bank account located in a foreign state, the costs of transferring the refunded amount shall be covered by the taxpayer.
A duplicate of a certificate issued on income derived and taxes paid to a taxpayer in Estonia would be eligible to enclose. In order to facilitate refunding process a taxpayer should inform the tax authorities about when did the payments and taxation take place in Estonia.
Thus, non-residents generally do not have to file income tax returns (depending on the type of income, they might have to, for example in case of taxable gain from transfer of properties and from business income).
Generally, non-residents may not claim for tax deductions and allowances available to residents and income tax shall be withheld from the gross amount, without permission of any deductions like basic exemption.
Unemployment insurance premiums withheld pursuant to clause 42 (1) 1) of the Unemployment Insurance Act from a payment made to a natural person are deducted form payment before calculation of the income tax to be withheld in accordance with § 41 of the Estonian Income Tax Act.
The deduction shall be calculated at the moment of payment already. The amount of income tax thus calculated will be regarded to be final tax. There is no need to submit income tax return to get the abovementioned deduction.
Although non-residents generally may not claim tax deductions, the deductions provided for resident natural persons in chapter 4 of the Estonian Income Tax Act can be made from the income subject to taxation in case a person, who is a resident natural person of another Contracting Party to the EEA (European Economic Area) Agreement, who submits an income tax return of resident natural person (§ 311 of the Income Tax Act).
Thus, the deductions from the Estonian taxable income have been made available for a non-resident natural person as prescribed in § 311 of the Income Tax Act. But the deductions could not be done at the time of withholding the income tax; it can be done once a calendar year only. A non-resident has an opportunity to file income tax return for a resident natural person not later than by 31 March of the following year in order to get the overpaid amount refunded.
The income tax return shall be filled in with the Estonian taxable income and the income tax withheld. Taxable income received from the resident country abroad shall also be filled in to provide the possibility to calculate the basic allowance amount of the Estonian taxable income of the person. Income of non-residents gained from foreign states is not taxable in Estonia.
Thus, the Estonian Tax and Customs Board shall refund the overpaid Estonian income tax to non-resident natural persons post factum once a year according to the filed income tax returns of resident natural persons.
