Lithuania GPM (individual activity annual income tax)

Lithuania: self-employed (individual activity) annual income tax return (GPM311) and payment, due 1 May

Gemini candidate audit (2026-09-08), confidence: likely. VMI's own forms listing confirms GPM311 is a real annual declaration form for individual-activity income tax. 1 May 2027 falls on a Saturday and is also a public holiday in Lithuania, so the practical deadline for that year is expected to shift to the next business day -- verify the exact date each year via VMI.
