I'm a sole proprietor and have so far (for the first 2 years of being a sole prop) been declaring my income for the previous year and then paying the calculated tax as usual. However, I just received a notice of estimated tax payment for 2024 (予定納税) stating that they want me to pay my 2024 tax this year (rather than at the end of the financial year in 2025) in September (the estimated amount). I'm confused. Is this normal?? Thanks!!
