How long does an IRAS audit usually take?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A desk audit can be resolved in a few weeks if the documentation is clear. A complex field audit may take several months to a year, depending on the volume of transactions.<\/span><\/p>\n<h3><b>2. Can I ask for an extension to provide documents?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Yes. If the request is voluminous, you can write to the auditing officer to request a reasonable extension. IRAS is generally accommodating if the request is made early.<\/span><\/p>\n<h3><b>3. What records must I keep for the 5-year period?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">You must keep all source documents, including sales invoices, receipts, <\/span><b>credit notes<\/b><span style=\"font-weight: 400;\">, bank statements, and accounting ledgers. Digital copies are acceptable provided they are legible.<\/span><\/p>\n<h3><b>4. If I find a mistake during an audit, can I still use the VDP?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">No. Once IRAS has notified you of an audit, you are no longer eligible for the Voluntary Disclosure Program for the items under review.
