Incorporation, accounting, tax, and CFO advisory under a single provider, so nothing falls through the cracks between service providers.
Every Singapore-incorporated company must maintain proper accounting records and file annual returns with ACRA and tax returns with IRAS, regardless of size. While companies can technically self-file, most engage an accounting and tax service provider to ensure accuracy and avoid penalties.
An accountant prepares your books and financial statements. A registered tax agent is specifically authorized to file and correspond with IRAS on your company’s behalf, which is required for certain tax matters and simplifies communication with the tax authority.
GST registration is mandatory once your company’s taxable turnover exceeds S$1 million in a 12-month period, though companies below this threshold can register voluntarily if it benefits their business.
Yes — this is a core part of our service. IBS manages all Singapore-side accounting, tax filing, and IRAS/ACRA correspondence, while our India liaison team coordinates directly with founders and finance teams based in overseas, so you don’t need to manage the process remotely on your own.
Late filings with ACRA or IRAS can result in penalties, and repeated non-compliance can escalate to further enforcement action. An accounting and tax agent helps track and meet these deadlines proactively as part of ongoing service.
Bookkeeping is typically included as the foundation of any accounting package, since accurate financial statements and tax filings depend on properly maintained books.
