My accountant is saying things about tax write-offs for businesses and I'm hoping someone can confirm if what she's saying is accurate, or if we need to find a new accountant. Basically what she is saying is that you cannot write off anything unless the receipt shows it was purchased for your company. For example, if you buy something for your business on Lazada using your personal account, you cannot write-off that expense for your business. You need need to set up your Lazada account to be a business account so the invoice shows your company name. The company is ran from a home office, so she says we cannot write-off a percent of our internet and electric bills, because the accounts are personal/home accounts and not business accounts. If clients come into town and we take them to lunch for a meeting, and we scan a QR code to pay using our personal banking account, we cannot write that off because it's not from a business banking account and we don't have a bill showing the company name. Is that accurate for how tax write-offs work in Thailand?
