AI image by LocalRankTax in Singapore touches most businesses and many individuals, from annual company filings and GST returns to cross-border questions. This page lists six firms that publish tax advisory or tax filing services on their own websites and also state an accounting-profession credential there, such as a public accounting registration or professional body membership. Tax advice is a professional-services matter rather than a licensed financial product, so this is a directory, not advice on any tax position. Entries are grouped editorially, not ranked, and every description is attributed to the firm. Two firms, BDO and 3E Accounting, also appear on our wider accounting firms list; here the focus is tax. Always confirm current terms with the firm.
1. BDO Singapore
BDO's Singapore site states that BDO LLP is an accounting limited liability partnership registered in Singapore and part of the international BDO network. Its tax section lists corporate tax advisory, personal tax advisory, goods and services tax, transfer pricing, private client services, and tax audit and investigation support, plus pages on migration solutions and crypto-asset tax reporting. The corporate tax page describes cross-border structuring support, guidance on mergers and reorganisations, and transfer pricing documentation. Its personal tax page describes support for employers and for employees working across borders. This is a larger network firm, so its published scope leans towards businesses with international dealings. It also appears on our accounting firms list, where the focus is wider. Check current terms on its website.
2. Lee & Hew Public Accounting Corporation
Lee & Hew's site presents the firm as an audit and accounting practice for small and medium-sized enterprises and corporate clients. It lists recognitions including registration with ACRA as a public accountant and as a filing agent, and displays an affiliation with the Institute of Singapore Chartered Accountants. A dedicated tax services page says it offers taxation advisory and compliance support to help businesses manage their tax obligations in Singapore, and its navigation points to areas such as corporate and personal tax planning, GST, withholding tax and transfer pricing. The firm describes its approach as end-to-end for company tax needs. The site publishes general enquiry contacts and weekday office hours. Confirm the scope of any engagement, and its current terms, with the firm directly.

3. Echtual PAC
Echtual describes itself on its website as an ACRA-registered public accounting corporation in Singapore serving small and medium-sized enterprises and the subsidiaries of multinational groups. Its site also displays a Chartered Accountant of Singapore credential and an ISCA membership milestone badge. The tax and compliance page describes work on corporate income tax computations and returns, Estimated Chargeable Income submissions, GST returns and registration questions, and responding to queries from the tax authority, alongside accounts compilation and XBRL filing for submission to ACRA. The page concentrates on company obligations rather than individual tax, so individuals should ask the firm what it covers. Echtual lists an office in the Suntec area and a contact form. Check current services and terms with the firm.

4. 3E Accounting
3E Accounting describes itself as a full-service accounting and corporate services provider and states on its site that it is a member of ISCA, ACCA and SIATP. Its tax pages list corporate income tax, personal income tax, GST and transfer pricing, and explain in general terms how Singapore company tax and start-up exemptions work. The firm also offers company incorporation, bookkeeping, payroll and corporate secretarial services, so tax is one part of a broader package for owners who want one provider. It says it has offices in Malaysia, Hong Kong and Indonesia as well as Singapore. Because the site mixes educational material with service descriptions, read its examples as general information rather than advice for your situation. It also appears on our accounting firms list.
5. Chartsworth
Chartsworth's site says its team are Chartered Accountants of Singapore who follow the ISCA Code of Professional Conduct and Ethics, and that team members also hold Singapore Chartered Tax Professionals membership. The site displays ISCA, SCTP and ACRA logos. Its tax services page describes four areas: corporate income tax compliance, GST registration and quarterly return filing, tax advisory on how a business strategy may affect its tax profile, and personal tax matters aimed at property owners and foreign investors with rental income. The firm also lists accounting, corporate secretarial and incorporation work. Its published pricing is a snapshot that may change, so ask for a current quotation. Contact details are on its website, including a contact page and a phone line.

6. IRIS Corporate Services
IRIS Corporate Services presents itself as a practitioner-led accounting, tax and corporate secretarial firm in Singapore, saying that senior qualified professionals oversee its engagements. Its site lists credentials including Chartered Accountant of Singapore, ACCA and Accredited Tax Advisor status for income tax and GST, and says it is an ACRA BizFile registered agent and an IRAS tax filing agent. Tax services listed include corporate income tax advisory and filing, GST registration and compliance, transfer pricing, correspondence and dispute handling with IRAS, and structuring around tax incentives. It is a smaller firm, so a reader can expect to deal with its founder-level team. The site publishes a phone number and an office address. Confirm what is in scope, and the terms, with the firm.
How to choose
- Start with the firm's credentials, as the firm itself states them. Look for a public accounting registration, membership of a professional body such as ISCA, CPA Australia or ACCA, or an accredited tax practitioner designation. Ask the firm to explain what each credential means for the work it would do for you.
- Match the service to your situation. Individuals, owner-managed companies, groups with overseas affiliates and GST-registered businesses each need different support. Read each firm's service pages closely, and ask directly whether it handles your category, rather than assuming a broad accounting firm covers every kind of tax.
- Understand the scope and the fee structure in writing before you engage anyone. Ask whether filing, advice and dealing with the tax authority are included or charged separately, how changes are billed, and who prepares and who reviews the work. Keep a copy of the engagement terms for your records.
- Be cautious about promises. No adviser can guarantee a tax outcome, and tax rules and filing deadlines change. Treat any marketing language about savings as a claim to question, and check current rules and deadlines on the Inland Revenue Authority of Singapore website. Ask how the firm would respond if a past filing were questioned.
- Check how the firm handles your records and your questions. Ask who your day-to-day contact will be, how you share documents securely, how quickly it responds, and what happens if the tax authority raises a query. Check what the firm will do if it discovers an error.
