⌛Time it takes to read this article: < 1 minutesLast updated: May 29, 2015 at 12:09 AM Today, I submitted my 2014 tax return (blue) to the Hiratsuka Tax Office. Until three years ago, I was filing as a corporation (limited company), so it was difficult to submit because there were so many documents. However, starting the following year, by switching to filing as a sole proprietor, the documents to be submitted became simpler, and all I had to do was submit financial statements and blue tax returns using PC accounting software, making tax work much easier. If you were a corporation, you would have to pay at least 70,000 yen in corporate inhabitant tax even if your business was in the red, and you were also required to take inventory and report assets, which was quite troublesome. If you are opening a small business, I recommend filing a blue tax return as a sole proprietorship rather than as a corporation. Although it is white, there is no special deduction of 650,000 yen for blue tax returns, so it is clearly a loss. On the other hand, if you choose blue, you will be required to submit financial statements, but if you know a little about accounting and can use accounting software, I think it would be easier to choose blue over white.
