Late-payment interest and unpaid invoices

Last checked against the sources 19 October 2026 · Published 15 October 2026

In short: If a payment is late, the creditor may claim late-payment interest (viivis) from the debtor from the moment the obligation fell due until it is properly performed () [1]. The statutory rate is the interest rate set out in § 94 of the Law of Obligations Act (võlaõigusseadus, VÕS) plus eight per cent per year () [1]. A business debtor may also be charged a debt-collection fee of 40 euros ( and 4) [2]; a consumer only within the limits set by law ( and 2) [3].

When does late-payment interest start to run?

Interest runs from the moment the obligation fell due until it is properly performed () [1]. Unless the contract provides otherwise, the creditor may demand performance once the due date or the period for performance has passed () [4].

If no due date or payment period was agreed in a reciprocal contract, the payment falls due at the latest 30 days after the invoice or a similar payment request reached the debtor () [5], and interest runs from that time () [1]. In other cases where the time of payment is not fixed, for example a claim for damages, interest runs from when the creditor notified the debtor of the claim or filed an action or an application for an expedited payment order () [1].

A debtor who concluded the contract in the course of business or professional activity may not rely on an agreed payment term longer than 60 days from receipt of the invoice or another event listed in –3, unless the contract expressly provides otherwise and this is not grossly unfair to the creditor in the circumstances () [5]. If the debtor is a person referred to in § 5 lg 2 of the Public Procurement Act, an agreed payment term longer than 60 days is void () [5].

The debtor does not have to pay late-payment interest for the time during which it could not perform because the creditor delayed accepting performance, or during which it lawfully refused to perform its obligation () [1].

How high is late-payment interest?

The interest rate under is, for each half-year, the most recent interest rate applied by the European Central Bank to its main refinancing operations before 1 January and 1 July of each year () [6]; Eesti Pank arranges its timely publication in Ametlikud Teadaanded () [6]. Eight per cent per year is added to it () [1]. For a long delay it is therefore worth checking the rate for each half-year separately. If the damage caused by the delay exceeds the late-payment interest, compensation for the damage exceeding it may be claimed if there is a claim for damages () [1].

If the contract provides for a higher interest rate than the statutory late-payment rate, the contractual interest rate is the late-payment rate () [1]. According to the Supreme Court, also allows the parties to agree on a late-payment rate higher than the statutory one; however, late-payment interest is compensation calculated as a percentage of the amount owed, and a charge for each day of delay agreed in a residential lease, which did not depend on the amount of unpaid rent, was an agreement on a contractual penalty, which is void in a residential lease (RK 2-15-8794/42) [7]. Under a consumer credit agreement, however, late-payment interest higher than the rate laid down in may not be claimed from the consumer for late payments () [8].

The law also sets limits:

  • No interest on interest. Late-payment interest may not be charged for late payment of interest, including late-payment interest; an agreement to the debtor's detriment is void () [1]. According to the Supreme Court, this ban cannot be artificially avoided, for example by extending the payment term; the parties may, however, agree on interest (not late-payment interest) on interest and late-payment interest that have fallen due (RK 3-2-1-175-14) [9]. The ban does not limit the right to claim compensation for damage caused by late payment of interest () [1].
  • Reduction. A person obliged to pay late-payment interest may ask for it to be reduced under () [1]: a court may reduce an unreasonably large amount to a reasonable one, but a reduction cannot be requested after payment ( and 3) [10].
  • Business debtor. A debtor acting in a business or professional capacity may not rely on an agreement restricting the right to late-payment interest if it is grossly unfair to the creditor in the circumstances () [1]; an agreement excluding late-payment interest from such a debtor is void () [1].

Can you charge for reminders and debt collection?

Business debtor. If the creditor may claim late-payment interest, it may claim compensation for debt-collection costs of 40 euros () [2]. This does not apply to a consumer debtor () [2].

Consumer debtor, where the creditor acts in a business or professional capacity () [3]:

  • while the contract is in force, for each obligation that has fallen due, a fee of up to 5 euros may be charged for one reminder letter only, and only if at least one free reminder was sent to the consumer first; the amount increases by 5 euros for each joint and several debtor or provider of security () [3];
  • after the contract has ended, up to 30 euros in total if the claim is up to 500 euros, up to 40 euros if the claim is over 500 euros and up to 1000 euros, and up to 50 euros if the claim is over 1000 euros; for the first paid reminder letter up to 15, 20 or 25 euros respectively and up to 5 euros for each of the next two letters, plus the same for each joint and several debtor or provider of security () [3];
  • after the contract has ended, the first paid reminder letter may be sent no earlier than seven days after the contract ended, and the second and third no earlier than seven days after the previous letter was sent () [3];
  • damage above these amounts may be claimed only in exceptional circumstances, in particular where the collection steps were exceptionally complex () [3];
  • an agreement to the consumer's detriment is void () [3].

How do you recover the debt through the courts?

A claim for a specific sum of money arising from a private-law relationship is decided by the court on application in expedited payment order proceedings () [11]; these are not available if the claim, including principal and ancillary claims, exceeds 8000 euros () [11]. They do not cover ancillary claims, such as late-payment interest, to the extent that these exceed the principal claim () [11]. They do not apply to a claim under a consumer contract if the late-payment rate agreed with the consumer exceeds three times the statutory rate () [11]. From 01.01.2027, when a claim under a consumer credit agreement is dealt with in expedited payment order proceedings, the creditor may claim only repayment of the principal of the credit granted to the consumer together with interest at the rate laid down in or late-payment interest at the rate laid down in the second sentence of , if these are not higher than the interest or late-payment rate agreed earlier () [12].

The application must show the principal and ancillary claims separately and, where late-payment interest is claimed, its rate and the period for which it is calculated () [13]. From 01.01.2027, for a claim under a consumer credit agreement the application must say so, give a detailed overview of the drawdown of the credit and of the payments under the agreement and a comparative calculation of all the consumer's payments towards principal, interest and late-payment interest, attach the agreement on which the claim is based, including the payment schedule, and state the annual percentage rate of charge () [14]. The state fee is three per cent of the claim, but not less than 65 euros () [15]. In an action, late-payment interest may be claimed so that the court awards it as a fixed sum up to the judgment and thereafter as a percentage of the principal claim () [16].

The limitation period for a claim arising from a transaction is three years () [17]; for a claim for agreed payment it starts at the end of the year in which the claim fell due () [18]. Limitation is interrupted and starts again if the debtor acknowledges the claim, for example by paying part of it ( and 2) [19].

What the law says

  • „Rahalise kohustuse täitmisega viivitamise korral võib võlausaldaja nõuda võlgnikult viivitusintressi (viivis), arvates kohustuse sissenõutavaks muutumisest kuni kohase täitmiseni.“ [1] (translation: in the event of delay in performing a monetary obligation, the creditor may claim late-payment interest from the debtor from the moment the obligation falls due until it is properly performed; ) – the right to interest follows from the law.
  • „Viivise määraks loetakse käesoleva seaduse §-s 94 sätestatud intressimäär, millele lisandub kaheksa protsenti aastas.“ [1] (translation: the late-payment rate is the interest rate set out in § 94 of this Act plus eight per cent per year; ) – this is the statutory annual rate.
  • „Viivist ei ole lubatud nõuda intressi, sealhulgas viivise, ega muu raha kasutamise tasu maksmisega viivitamise korral.“ [1] (translation: late-payment interest may not be charged for late payment of interest, including late-payment interest, or of any other charge for the use of money; ) – no interest on accrued interest.
  • „Kui võlausaldaja võib nõuda viivist, võib ta nõuda võlgnikult võla sissenõudmiskulude hüvitamist summas 40 eurot.“ [2] (translation: if the creditor may claim late-payment interest, it may claim compensation for debt-collection costs of 40 euros from the debtor; ) – this applies to a business debtor.

What to do

  1. Find the due date in the contract or invoice; if there is none, the payment falls due at the latest 30 days after the invoice reached the debtor () [5].
  2. Calculate interest on the amount owed from the due date until payment () [1], using the rate for each half-year () [6], and do not charge interest on interest () [1].
  3. Send a reminder and give a reasonable additional period for payment () [20]; during that period you may claim late-payment interest () [20]. Send a consumer at least one free reminder before a paid one () [3].
  4. Claim the 40-euro debt-collection fee from a business debtor () [2].
  5. If the debt is still unpaid, apply for an expedited payment order for a claim of up to 8000 euros () [11]; for a larger claim, file an action.
  6. Keep an eye on the limitation period (; ) [17] [18].

Frequently asked questions

Does the contract need a late-interest clause?

No. In the event of delay in paying money, the creditor may claim late-payment interest under the law (; ) [1] [21].

Can the 40-euro fee be charged to a private individual?

Not if they are a consumer: does not apply to a consumer debtor () [2]. Collection costs may be claimed from a consumer only within the limits of ( and 2) [3].

What does a partial payment cover first?

If, in addition to the principal monetary obligation, the debtor must pay costs and interest, the payment is deemed to cover first the costs, then interest that has already fallen due, and finally the principal obligation () [22]. The debtor may not set a different order without the creditor's consent () [22]. Under a consumer credit agreement the order is different: if a payment the consumer made under the agreement is not enough to perform all obligations that have fallen due, it is applied first to the costs of collecting the debt, second to the principal owed, third to interest and fourth to other obligations () [8]; this does not apply if the consumer pays under an enforcement instrument drawn up for recovering interest as the principal claim () [8]. From 01.01.2027, when a claim under a consumer credit agreement is dealt with in expedited payment order proceedings, all payments the consumer made in that obligation are applied first to the principal debt, second to interest and third to late-payment interest, to the extent laid down in () [12]; in that case the order laid down in does not apply () [23].

What if the agreed late-payment interest is very high?

The person obliged to pay it may ask for it to be reduced () [1]; a court may reduce an unreasonably large amount to a reasonable one () [10].
