How it works
Do as much yourself as you like. We do the rest.
We do the bookkeeping
Your accountant checks everything, matches bank payments to invoices and files tax returns on time. We only ask when we really need to.
You see the result
Turnover, outstanding invoices and upcoming taxes are visible in the client portal straight away, not only at the end of the month.

About us
35 years. The same family. New tools.
Simar was founded on 14 August 1991, six days before Estonia restored its independence. Back then, companies were entered in the enterprise register. After the Commercial Code came into force, Simar was re-registered in the Commercial Register in 1998. We have kept accounts in kroons and euros, on paper and in the cloud. Now we have built our own client portal, because we wanted our clients to see their figures as clearly as we do.

Three things we promise every client
1
Deadlines are met
Tax returns are filed before the 10th and 20th, the annual report before 30 June. Our clients don't need to pay interest on late tax.
2
Figures you can understand
Turnover, profit, taxes and balances are always visible in the client portal. We explain what the figures mean, rather than just sending a file.
3
You have your own accountant
A dedicated person who knows your company, answers the phone and e-mails, and meets you in Nõmme when needed.
How getting started works
Switching accountants takes one meeting on your part
The most common reason companies don't switch accountants is fear of a mess. Here is how the takeover works with us.
30 minutes · free
1. Introductory call
We talk about the size of your business and your line of work. Within three working days we send you a written quote.
One meeting or online
2. Contract and access
Authorisations in e-MTA and the Commercial Register, receiving e-invoices and setting up the flow of bank statements.
We do it
3. Takeover
We take over the database, balances and unfinished periods from your previous accountant ourselves. We tell you honestly if something is out of order.
At the end of the first month
4. Client portal and first report
We open the client portal for you and go through turnover, expenses, taxes and balances together. From then on everything runs as routine.

Annual report 2025: what to keep in mind before 30 June
The deadline for the annual report is 30 June. If it is late, the Commercial Register may impose a fine and, after a longer delay, start deletion proceedings.

Before preparing the report, we reconcile balances with banks, customers and suppliers, take stock of inventory and fixed assets, and review transactions with board members and shareholders. Micro and small companies have a shorter report, but small companies are also required to include a management report. If reports have not been filed for several years, all missing years must be filed. We can help in these cases too.
The standard VAT rate is 24 percent
From 1 July 2025, the standard VAT rate is 24%. Prices in long-term contracts and orders should be reviewed.

Special attention is needed for prepayment invoices issued before the change where the goods or services were delivered after it, and for ongoing contracts where the price was agreed including VAT. Different transition rules apply to businesses using cash-based VAT accounting. The income tax rate has been 22% since 2025, and the reduced 14% rate on regularly paid dividends has been abolished.
Frequently asked questions
Can I create invoices myself?
Yes. You create a sales invoice in the client portal in a couple of minutes, and it goes to your customer as a PDF and an e-invoice. You approve purchase invoices in the same place. If you prefer, we can continue to do the invoices for you. Access is personal, and data is stored in the European Union.
Do I have to do anything myself?
Very little. Send your invoices and expense documents, and let us know about payroll changes once a month. We handle the tax returns, reports and communication with the tax authority.
How does switching accountants work?
For you, it is one meeting and one signature. We take over the database, balances and unfinished tax returns from your previous accountant.
How quickly can I start?
Within a week of signing the contract. The easiest is to switch at the start of a month or quarter.
What happens if I am late with my tax returns?
We restore your accounts and file the missing returns. Interest is 0.06% per day, so it pays to start right away.
Do you serve e-residents and work in English?
Yes. Meetings online, documents digitally, communication in English.
How do I send documents?
The most convenient way is to create the sales invoice yourself in the client portal, or have purchase invoices sent as e-invoices, which reach us automatically. E-mail, a phone photo of a receipt, or paper brought to our office on Rännaku pst work too.
Do you also do just the annual report?
Yes. If you have kept the books yourself during the year, we prepare and file the annual report as a separate service. We review the balances first and tell you if anything needs correcting.
Do you also advise on tax matters?
Yes. Short questions, such as whether an expense can be booked or how dividends are taxed, are included in the service. More extensive advice, such as a company reorganisation or a tax audit, is agreed separately.
How long is the contract and how do I end it?
The contract is open-ended with no minimum term. It can be terminated with one month's notice, and we hand over all data properly.
Let's talk about your accounting.
