Lithuania: monthly income tax declaration (GPM313) due by the 15th
Every month, due by the 15th. · Only applies to months in which the company paid salary, board member fees or other GPM-reportable income; a month with no such payments needs no GPM313. The 15th is the filing deadline; the tax payment deadline within the month depends on when the payment itself was made (by the 15th for payments up to the 15th, by month-end for later payments).
What changes
Employers and other payers of income subject to Lithuanian personal income tax (GPM), such as salary, board member fees, or other GPM-withholdable payments, must submit the monthly declaration GPM313 to VMI by the 15th day of the month following the month of payment. The tax withheld must itself be paid on a schedule tied to the payment date within the month, not uniformly on the 15th.
Who is affected
Every Lithuania-registered company that pays salary, board member remuneration or other GPM-reportable income in a given month, including a single-person UAB/MB paying its own director/board member fee; a month with no such payments needs no GPM313.
