Annual Declaration Deadlines for Companies in Lithuania: What Businesses Need to Know

Every company operating in Lithuania must comply with various annual reporting and tax obligations. Missing declaration deadlines can result in penalties, interest charges, or unnecessary administrative complications. Understanding the key annual filing dates helps businesses stay compliant and avoid issues with the Lithuanian authorities.

Annual Corporate Income Tax Return

One of the most important obligations for Lithuanian companies is the submission of the annual corporate income tax return.

Companies must submit their annual profit tax declaration (PLN204 form) and pay any outstanding corporate income tax by 15 June of the following year. The declaration covers the company's financial results for the previous tax period, which is typically the calendar year.

For example, if a company's financial year ends on 31 December 2025, the annual profit tax return must generally be filed by 15 June 2026.

Submission of Annual Financial Statements

Lithuanian legal entities are required to prepare annual financial statements and submit them to the Register of Legal Entities managed by the Centre of Registers.

The annual financial statements must generally be approved by shareholders or members and submitted within 30 days after approval, but no later than 5 months after the end of the financial year for most companies.

For companies whose financial year matches the calendar year, the practical deadline is usually 31 May.

The submitted package typically includes:

• Balance sheet

• Profit and loss statement

• Explanatory notes

• Other required financial reports depending on the company's size and legal form

Annual Personal Income Declarations for Company Owners

If company shareholders, members, or directors have received dividends or other taxable payments, they may also need to submit personal income tax declarations.

The annual personal income tax return is generally due by 4 May of the following year.

This obligation applies to individuals rather than the company itself, but business owners should be aware of the deadline.

Annual Reporting for VAT-Registered Companies

Companies registered as VAT payers are generally required to submit VAT returns monthly throughout the year. Therefore, there is no separate annual VAT declaration in most cases.

However, businesses should ensure that all monthly VAT declarations have been submitted correctly and that any discrepancies are resolved before year-end reporting.

Statistical and Industry-Specific Reporting

Certain companies may have additional reporting obligations depending on their activities.

For example, some businesses may receive reporting requests from:

• Statistics Lithuania

• The Bank of Lithuania

• Environmental authorities

• Other regulatory institutions

The applicable deadlines depend on the specific reporting requirements and industry sector.

Why Meeting Deadlines Matters

Timely filing helps businesses avoid penalties, maintain good standing with Lithuanian authorities, and ensure smooth cooperation with banks, partners, and investors.

Many companies choose to work with accountants or accounting firms to monitor deadlines and prepare declarations accurately. Even small businesses with limited activity should review their annual obligations each year to ensure full compliance.

Key Annual Deadlines at a Glance

For most Lithuanian companies operating on a calendar-year basis, the main annual deadlines are:

• 4 May – Personal income tax declarations for individuals.

• 31 May – Submission of annual financial statements (in most cases).

• 15 June – Annual corporate income tax return (PLN204) and payment of profit tax.

Keeping track of these dates can help businesses avoid unnecessary penalties and maintain full compliance with Lithuanian tax and corporate regulations.
