Frequently Asked Questions
What documents do I send Acpedia each month?
Purchase and sales tax invoices, receipts, bank statements for every account, payroll documents, and withholding tax documents. If a month has no transactions, post “no documents this month” in the group so we can close the period.
What happens if I send documents late?
We still file on time using the information available, then adjust the following month. If the missing documents affect the tax payable, an additional filing may be required, along with surcharges and penalties under the law.
What are the penalties for late filing?
It depends on the return. Generally there is a criminal fine for the late filing itself, plus a surcharge calculated on the tax payable. We always confirm the exact amount with you before proceeding.
Can I get copies of past financial statements or tax returns?
Yes. Tell us the year and document type in the LINE group and we will send the files within one to two business days.
Can I switch accounting software mid-year?
Yes, though switching at the start of a financial year keeps opening balances and tax reports continuous. If a mid-year switch is necessary, we plan the opening balances before you go live on the new system.
How do I reach you outside office hours?
Leave a message in the LINE group at any time and we will reply during the next business hours. For anything urgent close to a filing deadline, start your message with “ด่วน-ยื่นภาษี”.
