TLDR: In 2026, Sleek ranks first overall for foreign founders seeking digital accounting, tax, incorporation and corporate compliance in one platform. Counto suits technology-focused SMEs that want continuous bookkeeping, financial dashboards and dedicated human support. InCorp and RSM Singapore offer broader advisory, payroll and cross-border capabilities for growing businesses. Timcole publishes useful transaction-based bookkeeping prices, while Osome offers packaged online accounting and tax services. IRAS requires companies to retain specified financial and transaction records for at least five years from the relevant Year of Assessment.
The best accounting firms in Singapore for expats in 2026 are professional service providers that combine bookkeeping, financial statements, IRAS tax compliance and clear English-language support for foreign-owned businesses. IRAS states that a company must retain source documents, accounting records, schedules, bank statements and other business transaction records for at least five years from the relevant Year of Assessment. Sleek ranks first for most foreign founders because it combines digital accounting with incorporation and corporate compliance, while Counto leads for technology-driven bookkeeping. InCorp and RSM Singapore suit businesses requiring broader regional, payroll or advisory capabilities.
How were the best accounting firms in Singapore for expats ranked?
The ranking weighs bookkeeping scope, corporate tax support, GST capability, payroll, financial reporting, software access, foreign-founder services, pricing transparency and independent review signals.
The editorial score measures suitability for an expat, freelancer or SME owner who needs recurring accounting support in Singapore. Bookkeeping quality and filing scope receive greater weight than incorporation speed because accurate records affect tax returns, management decisions and statutory reporting after the company starts operating.
Review signals use ratings and review counts visible on official firm pages or established review platforms during the August 2026 review. Public ratings change as customers add reviews, and global profiles can include experiences from several countries rather than Singapore alone.
Service descriptions come from each firm’s published Singapore pages. Prospective clients should obtain a written engagement letter because transaction limits, bookkeeping frequency, software subscriptions, tax filings and ad hoc work can sit outside a headline package.
Which accounting firms are best for expats and SMEs in Singapore?
Sleek ranks first overall, followed by Counto, InCorp, RSM Singapore and Osome for businesses seeking a combination of accounting, tax and ongoing support.
| Rank | Firm | Editorial rating | Published review signal | Best for | Core service scope | Published starting price |
|---|---|---|---|---|---|---|
| 1 | Sleek | 4.7/5 | 4.5/5 from 473 reviews shown on its official About page | Foreign founders and digital SMEs | Bookkeeping, financial reporting, corporate tax, GST, payroll, incorporation and corporate secretary | Accounting packages reported from S$75 monthly when billed annually; scope varies |
| 2 | Counto | 4.6/5 | No comparable rating and count displayed on the reviewed accounting page | Continuous digital accounting | Unlimited-transaction bookkeeping, tax filing, payments, payroll, dashboards and CFO services | Quote based on revenue or transaction volume |
| 3 | InCorp | 4.5/5 | Official site states 8,000+ Singapore business clients; no comparable star rating displayed | Growing and regional businesses | Bookkeeping, financial statements, GST, tax, payroll, XBRL, audit liaison and advisory | Custom quote |
| 4 | RSM Singapore | 4.4/5 | No comparable rating and count displayed on the reviewed service page | Complex SMEs and regional operations | Accounting outsourcing, tax, payroll, audit, advisory, systems and CFO support | Custom quote |
| 5 | Osome | 4.2/5 | Trustpilot displayed 3.3/5 from 666 reviews | Online annual compliance packages | Bookkeeping, management report, financial statements, ECI and corporate tax filing | Package-based quote |

| 7 | Hawksford | 4.0/5 | Official site states more than 1,000 Singapore incorporations; no comparable star rating displayed | International structures and market entry | Accounting, tax, incorporation, corporate services and cross-border support | Custom quote |
| 8 | 3E Accounting | 3.9/5 | Trustpilot displayed 2.6/5 from 23 reviews | One-stop corporate administration | Bookkeeping, financial statements, XBRL, corporate tax, GST, payroll and incorporation | Custom quote |

| 10 | OneStop Professional | 3.7/5 | No comparable rating and count displayed on the reviewed service material | Traditional professional support | Bookkeeping, accounting, tax planning, corporate services and audit | Custom quote |
Editorial ratings assess overall fit for the stated audience rather than professional competence in every engagement. An SME with complex transfer pricing or audit requirements can reasonably choose a lower-ranked specialist over a higher-ranked digital bookkeeping provider.
Why is Sleek the best overall accounting firm for expats?
Sleek is the best overall option for many expat founders because it combines SME accounting, corporate tax, payroll, incorporation and corporate compliance within one digital platform.
Sleek’s accounting services cover recurring bookkeeping, financial reporting and tax-ready accounts. Sleek also offers corporate tax filing, GST support, payroll and corporate secretary services, allowing a foreign founder to coordinate several Singapore obligations through one provider.
Sleek supports company incorporation for foreigners and offers related registered-office and nominee-director services. ACRA states that foreigners must engage a Corporate Service Provider to reserve a business name and register a business structure, making integrated incorporation particularly relevant to overseas founders.
Sleek states that its accounting packages start from S$75 per month when billed annually on the Annual Filing and Bookkeeping tier. Customers should confirm bookkeeping frequency, transaction limits, software access, GST work and response times because the lowest tier does not represent every operating business’s requirements.
Sleek’s official About page displayed a 4.5 rating from 473 reviews during the review. Review counts differ across Sleek pages and platforms, so clients should inspect recent accounting-specific feedback rather than relying on the aggregate score alone. Sleek SME services and Sleek accounting pricing information describe its current scope.
Why does Counto rank highly for small business accounting in Singapore?
Counto ranks highly because it combines automated bookkeeping with a dedicated team that includes a bookkeeper, Chartered Accountant, tax specialist and Customer Success Manager.
Counto’s accounting plan includes bookkeeping, unlimited transactions, tax filing and automated payments. The platform connects financial data and presents accounting, payroll and reporting information through a unified dashboard.
Counto bases pricing on business scale rather than hourly billing. Counto states that customers can use the lower of revenue-based or transaction-based pricing, but businesses should obtain a written quote for payroll, GST, catch-up bookkeeping and accounts payable support.
Counto supports Xero and QuickBooks migrations alongside its proprietary platform. Counto also states that its tax software has achieved IRAS ASR+ Tier 2 qualification.
Counto suits founders who want current financial visibility instead of annual bookkeeping performed shortly before tax filing. Counto accounting services and Counto small-business accounting explain the service model.
When is InCorp the right accounting provider?
InCorp is the right provider for businesses that need scalable accounting, tax, payroll and cross-border corporate support across Asia-Pacific markets.
InCorp provides bookkeeping, bank reconciliation, financial statements, GST registration and filing, XBRL preparation, payroll, audit liaison and accounting-system implementation. InCorp supports monthly, quarterly, semi-annual or annual reporting arrangements.
InCorp works with startups, SMEs, established corporations and multinational companies. InCorp’s regional presence can help an expat-owned business coordinate Singapore accounting with operations in other Asia-Pacific jurisdictions.
InCorp supports Xero implementation, training and data migration. A company with an internal finance employee can therefore engage InCorp for system setup or specialised compliance work without outsourcing every daily transaction.
InCorp’s official site states that the group supports more than 8,000 businesses in Singapore and 20,000 clients globally. InCorp Singapore accounting services and InCorp Global service information describe its capabilities.
Why should growing SMEs consider RSM Singapore?
Growing SMEs should consider RSM Singapore when their needs extend beyond routine bookkeeping into audit, tax structuring, systems, finance staffing or strategic advisory.
RSM Singapore provides outsourced accounting, payroll, formation, corporate compliance, tax, audit, technology and advisory services. RSM can scale services from startups to multinational corporations operating in Singapore and other markets.
RSM Singapore describes itself as the largest professional services firm outside the Big Four in Singapore. RSM Singapore also participates in the international RSM network, giving cross-border businesses access to accounting and advisory capabilities beyond Singapore.
RSM’s CFO2SME service supports budgeting, management reporting, cash-flow management, cost analysis, tax planning and financial-statement analysis. A growing company can use the service when it needs senior financial input without hiring a full-time CFO.
RSM usually requires a tailored proposal instead of publishing a low-cost standard package. RSM Singapore business solutions and RSM Singapore company information outline the available services.
Who should consider Osome for accounting and tax?
Osome suits founders who prefer a packaged online service for bookkeeping, financial statements and annual corporate tax filings.
Osome’s accounting package includes bookkeeping, a management report, preparation of Unaudited Financial Statements, preparation and filing of Estimated Chargeable Income, and corporate tax filing through Form C, Form C-S or Form C-S Lite where applicable.
Osome provides digital document submission and online communication. The service model can work well for straightforward companies with organised transaction records and predictable annual compliance needs.
Osome’s Trustpilot profile displayed 3.3/5 from 666 reviews during the August 2026 review. Recent feedback included positive comments about responsive staff and timely submissions alongside complaints about delays, package scope, communication and additional costs.
Osome customers should confirm whether bookkeeping occurs monthly, quarterly or annually and whether Xero, GST, payroll, catch-up work and audit support cost extra. Osome accounting package and Osome Singapore accounting services state the core inclusions.
Why is Timcole useful for price-conscious SMEs?
Timcole is useful for price-conscious SMEs because it publishes transaction-based guidelines for monthly and annual bookkeeping.
Timcole lists monthly bookkeeping from S$200 for a non-GST company with fewer than 30 monthly transactions. The published monthly scope includes bookkeeping, document verification, bank reconciliation, a management report and cloud-accounting data entry.
Timcole lists annual accounting from S$1,600 for fewer than 120 annual transactions. The published annual scope includes bookkeeping, bank reconciliation, an annual management report, Unaudited Financial Statement compilation and simplified Form C-S work.
Timcole also provides payroll, corporate tax, GST, XBRL, incorporation and corporate secretary services. Timcole states that fees vary with transaction volume and complexity, while cloud software subscriptions and physical-document handling can sit outside the basic price.
Timcole Advisory Pte Ltd was renamed HeySara Accounting Pte Ltd effective 1 November 2024, while the Timcole website continues to publish accounting information. Timcole bookkeeping fees and HeySara accounting services provide the current service descriptions.
When does Hawksford suit a foreign-owned business?
Hawksford suits foreign-owned businesses that need Singapore accounting alongside international incorporation, corporate governance or cross-border structuring support.
Hawksford provides accounting, tax and corporate services from its Singapore office. Hawksford states that it has helped more than 1,000 businesses incorporate in Singapore.
Hawksford’s broader service model can suit an overseas group establishing a Singapore subsidiary, regional headquarters or investment structure. A small freelancer requiring only annual bookkeeping may find a digital SME package simpler and less expensive.
Hawksford publishes limited standard accounting prices, so prospective clients should request a scope separating bookkeeping, management accounts, annual financial statements, corporate tax, GST and payroll. Hawksford Singapore lists its local service categories.
What does 3E Accounting offer SMEs?
3E Accounting offers SMEs a broad one-stop scope covering bookkeeping, financial statements, tax, payroll and corporate administration.
3E Accounting provides monthly bookkeeping, financial-statement preparation, XBRL filing, corporate accounting and cloud-accounting support through Xero and QuickBooks. The firm also offers corporate tax, GST, incorporation and compliance services.

3E Accounting’s Trustpilot profile displayed 2.6/5 from 23 reviews during the August 2026 review. The limited review sample included both service feedback and complaints concerning process, communication and package requirements.
A prospective client should request named deliverables, turnaround expectations, service dependencies and offboarding terms in writing. 3E Accounting services describes its accounting scope.
When should an SME consider Bestar?
Bestar merits consideration when a business wants bookkeeping, tax, audit and broader financial advisory from a single provider.
Bestar lists bookkeeping, financial-statement compilation, income tax, audit, payroll outsourcing, corporate secretarial work, incorporation and financial advisory among its Singapore services.
Bestar can suit businesses that expect future audit, due-diligence, valuation or transaction-support needs. A simple low-transaction company should compare Bestar’s tailored quote with published SME packages from Sleek and Timcole.

Bestar Singapore and Bestar company information provide the published service scope.
Who should consider OneStop Professional?

OneStop Professional’s published service material lists bookkeeping, accounting and tax-planning capabilities. The firm also presents corporate and audit-related services for businesses requiring broader compliance support.
OneStop Professional publishes less standardised online pricing information than leading digital providers. Prospective clients should request a detailed engagement letter that defines bookkeeping frequency, transaction volume, software, financial statements, ECI, corporate tax, GST and payroll.
OneStop Professional can be a reasonable shortlist candidate for owners who value direct professional interaction over a platform-led workflow. OneStop Professional service material outlines its published capabilities.
What accounting services does an expat-owned SME usually need?
An expat-owned SME usually needs bookkeeping, annual accounts and corporate tax support, while GST, payroll, XBRL and audit depend on its activities and reporting position.
| Service | Purpose | Typical frequency | Questions for the firm |
|---|---|---|---|
| Bookkeeping | Records income, costs, assets, liabilities and bank activity | Monthly, quarterly or annually | How many transactions, accounts and currencies are included? |
| Bank reconciliation | Matches accounting entries with bank records | Monthly or quarterly | Does the firm investigate unmatched transactions? |
| Management accounts | Shows profit, financial position and cash movement | Monthly or quarterly | Are commentary, budgets and comparisons included? |
| Unaudited Financial Statements | Supports annual reporting and tax work | Annually | Are directors’ statements and required notes included? |
| Estimated Chargeable Income | Reports estimated taxable profit to IRAS | Annually, subject to applicable filing rules | Does the fee include tax computation and submission? |
| Corporate tax return | Files Form C, Form C-S or Form C-S Lite where eligible | Annually | Does the firm answer follow-up questions from IRAS? |
| GST | Covers registration, transaction coding and GST returns | Commonly quarterly after registration | Are GST reconciliation and filing included? |
| Payroll | Calculates salaries and prepares payroll records | Monthly | Are payslips, IR8A, IR21, CPF and levy work included where applicable? |
| XBRL | Converts financial statements for applicable ACRA filing | Annually where required | Does the quote include validation and correction of errors? |
| Audit | Provides an independent statutory audit where required | Annually where applicable | Which registered Public Accounting Entity signs the report? |
A service labelled “annual accounting” can mean year-end bookkeeping performed once each year. Businesses that need current cash-flow information should specify monthly close dates and management reports.
What is the difference between bookkeeping, accounting and audit?
Bookkeeping records transactions, accounting converts records into reports and tax filings, and audit independently examines financial statements.
| Function | Main work | Regulatory distinction |
|---|---|---|
| Bookkeeping | Records invoices, receipts, payments, journals and bank transactions | ACRA states that a provider does not need PAE registration solely for non-public accountancy services such as bookkeeping or tax advice |
| Accounting | Reconciles records, prepares financial statements and supports management or tax reporting | Qualifications and service scope vary by provider and engagement |
| Tax compliance | Prepares ECI, corporate income tax, GST and related submissions | The company remains responsible for complete and accurate information supplied for filing |
| Audit | Independently examines and reports on financial statements | ACRA states that Public Accounting Entities must register under the Accountants Act 2004 to provide public accountancy services |
A bookkeeping brand should not be assumed to be a statutory audit firm. An SME requiring an audit should verify the Public Accounting Entity and public accountant through ACRA.
How much do accounting services cost in Singapore?
Small business accounting in Singapore can range from a low-cost annual package to several thousand dollars each month, depending on transaction volume and complexity.
| Cost driver | Lower-complexity profile | Higher-complexity profile |
|---|---|---|
| Transaction volume | Fewer than 120 annual transactions | Hundreds or thousands of monthly transactions |
| Bank and payment accounts | One Singapore-dollar bank account | Multiple banks, gateways and foreign currencies |
| Bookkeeping cadence | Annual or quarterly bookkeeping | Monthly close with management reporting |
| Revenue model | Simple services and bank payments | Inventory, subscriptions, e-commerce or project accounting |
| Tax scope | ECI and Form C-S | Form C, transfer pricing, incentives or cross-border tax |
| GST | Non-registered business | GST registration, quarterly returns and reconciliations |
| Payroll | No employees | Local and foreign employees, benefits and tax clearance |
| Historical condition | Clean opening balances | Catch-up bookkeeping and prior-year corrections |
| Reporting | Basic Unaudited Financial Statements | Consolidation, XBRL, audit support or investor reporting |
Sleek reports entry accounting packages from S$75 monthly when billed annually, while Timcole publishes monthly bookkeeping from S$200 and annual accounting from S$1,600 for its lowest transaction bands. Headline prices are not directly comparable because inclusions differ.
How should an expat choose an accountant in Singapore?
An expat should choose an accountant by defining the required deliverables, checking credentials, comparing written scopes and testing communication before signing a long contract.
- List the business activities. Record monthly transaction volume, bank accounts, currencies, employees, inventory, payment gateways and overseas transactions.
- Define the reporting frequency. Choose annual compliance, quarterly reporting or a monthly close with management accounts.
- Identify mandatory work. Confirm corporate tax, GST, payroll, XBRL, audit and corporate-secretarial requirements.
- Check the legal provider. Verify the contracting entity, ACRA registration and Corporate Service Provider status when corporate services form part of the engagement.
- Verify audit credentials separately. Confirm the registered Public Accounting Entity and public accountant when statutory audit services are required.
- Request an itemised quote. Separate bookkeeping, financial statements, ECI, tax returns, GST, payroll, software and government fees.
- Test communication. Ask a technical question and assess the clarity, response time and identity of the person who will manage the account.
- Review exclusions and limits. Check transaction bands, bank-account limits, foreign currencies, catch-up work and amendment fees.
- Check data ownership. Confirm access to ledgers, documents, software subscriptions and exports during and after the engagement.
- Review offboarding terms. Establish the notice period, handover format, outstanding-work process and document-return timeline.
What records must a Singapore company keep?
IRAS requires a company to maintain proper financial transaction records and retain specified documents for at least five years from the relevant Year of Assessment.
IRAS identifies source documents, accounting records, schedules, bank statements and other records connected with the company’s transactions as records that must be retained. The requirement continues even when an outsourced accounting firm stores or processes the information.
GST-registered businesses must keep proper business and accounting records for at least five years to support GST declarations. Records include sales documents, purchase invoices, expense receipts, bank statements, general ledgers and financial statements.
The company should retain direct access to its source documents and accounting exports. Outsourcing bookkeeping transfers the work to a provider, but outsourcing does not transfer the company’s responsibility for complete records. IRAS record-keeping requirements provide the official rules.
What should foreign founders know before starting a Singapore business?
Foreign founders must use a Corporate Service Provider to reserve a business name and register a Singapore business structure.
ACRA states that foreigners must engage a Corporate Service Provider to reserve a name and register a business structure. Foreign founders must also meet the applicable local-residency requirements.
FIN holders should check with the pass issuer, such as MOM or ICA, before registering a business or accepting a role. ACRA states that Employment Pass holders must first seek a Letter of Consent from MOM when the stated situation requires it.
An accounting firm can support incorporation and bookkeeping without controlling work-pass eligibility. A foreign founder should treat business registration, immigration permission and personal tax residence as related but separate questions. ACRA requirements and eligibility explain the rules for foreigners.
Which firm suits different expat and SME profiles?
Different business profiles produce different rankings because transaction volume, reporting needs and cross-border complexity determine the right accounting model.
Example 1: A foreign founder launching a consulting company. Sleek can suit a founder who needs incorporation, corporate secretary, annual bookkeeping and tax compliance through one digital provider.
Example 2: A technology SME seeking monthly visibility. Counto can suit a company that wants continuous bookkeeping, automated payments, financial dashboards and access to a dedicated accounting team.
Example 3: A regional company opening a Singapore subsidiary. InCorp or Hawksford can suit a group that needs local accounts alongside regional corporate, payroll and market-entry support.
Example 4: A growing SME preparing for financing. RSM Singapore can suit a company requiring management reporting, cash-flow planning, tax advice and CFO-level support.
Example 5: A small local company with predictable transactions. Timcole can suit an owner who values published transaction bands and can organise records according to the package requirements.
Example 6: A straightforward company seeking online annual compliance. Osome can suit an organised business after the owner confirms bookkeeping frequency, package exclusions and response expectations in writing.
Example 7: A business requiring audit and advisory. RSM Singapore or Bestar can suit a company after the contracting Public Accounting Entity and audit scope are verified.
What warning signs should an SME check before signing?
An SME should investigate vague deliverables, unclear bookkeeping frequency, inaccessible accounting data, undocumented add-on fees and uncertain responsibility for filing deadlines.
A proposal that says “accounting and tax” without naming the included reports can hide important exclusions. The engagement letter should identify bookkeeping, reconciliations, financial statements, ECI, corporate tax forms, GST, XBRL and payroll separately.
A provider that retains exclusive control of the ledger can make switching difficult. The client should hold administrator or export access to accounting data and copies of every source document.
A low annual price can exclude catch-up work, foreign currencies, payment gateways, additional bank accounts or tax questions. The client should obtain a rate card for work outside the recurring package.
A provider can prepare and submit filings, but directors retain responsibility for company information and governance. Company officers should review financial statements and tax computations before approving submission.
