Why Sirus Infotech

Global compliance is not nine spreadsheets and five accountants. It's one system.

Every country has its own filings, its own deadlines, its own tax forms. The mistake most growing businesses make is hiring a different firm in each country — five disconnected vendors, five invoices, five timezones, no accountability. We built Sirus to fix exactly that.

One Engagement, Six Countries

Single MSA, single invoice, single Engagement Manager. You stop chasing five vendors across five timezones — we coordinate the underlying country teams.

Compliance Calendar Dashboard

Every filing across every jurisdiction in one dashboard with statutory and internal deadlines, status, and weekly review. Nothing falls through the cracks.

Local Specialists, Senior-Reviewed

Country experts who know HKFRS, FRS 102, UK GAAP, US GAAP, IFRS — every file reviewed by a senior partner before it leaves our office.

Direct-Service Jurisdictions

We needed a Delaware C-Corp, a Singapore Pte Ltd, and ongoing books in both — done in parallel. Sirus delivered all three in 7 weeks, with one Engagement Manager I could WhatsApp anytime. Saved us a fortune in coordination overhead.

UK Limited + UAE FZ-LLC + ongoing VAT in both. The Compliance Calendar dashboard is genuinely the best thing I've seen — every deadline visible months in advance. We've not missed a single filing in 18 months.

Honest, transparent and senior-led. They flagged a permanent-establishment risk in the UAE that our previous accountant had completely missed. Restructured cleanly and saved us a meaningful amount in corporate tax.

FAQ

Cross-border questions, answered straight.

Country-specific FAQs are on each country page. Below are the questions clients ask us about multi-jurisdiction setups and global compliance.

What does global tax compliance mean for a multi-jurisdiction business?
Global tax compliance is the discipline of meeting every tax, statutory and corporate reporting obligation in every country where your business has a legal presence, employees, customers or revenue. For a typical Indian SME going global, this can include corporate income tax in the home country, VAT or GST in the trading country, payroll taxes wherever staff are employed, withholding tax on cross-border payments, transfer pricing documentation between group entities, and statutory filings (annual return, financial statements, beneficial owner registers) in each jurisdiction. Sirus Infotech provides this end-to-end across the UK, USA, UAE, Singapore, Hong Kong and India under a single engagement letter and a single point of contact.
In which countries does Sirus Infotech provide tax registration and compliance services?
We provide direct services in India, the United Kingdom, the United States, the United Arab Emirates, Singapore and Hong Kong. Service lines include company incorporation, bookkeeping & accounting, VAT / GST / sales-tax registration, payroll, company secretarial work, statutory annual filings and audit liaison. Through our affiliate network we also support clients in Canada, Australia, Mauritius, Cayman Islands, the Netherlands and Germany on a project basis.
How do you coordinate filings across multiple countries without things falling through the cracks?
Every multi-country client gets a Compliance Calendar — a single dashboard listing every filing across every jurisdiction, with statutory due date, internal due date (always 7 days earlier), responsible team member and current status. The calendar is reviewed every Monday with the client lead. Reminders fire 30, 14 and 7 days before each deadline. We also assign a dedicated Engagement Manager who is the single point of contact across all countries — you don't deal with five different teams in five different time zones.
Can you set up entities in multiple countries simultaneously?
Yes — and parallel formation is often the most efficient approach. A typical scenario is an Indian founder who needs a Delaware C-Corp, a UAE FZ-LLC and a Singapore Pte Ltd at the same time for fundraising, customer billing and APAC sales respectively. We coordinate all three formations on parallel timelines, handle the cross-shareholding structure if a holding company is involved, and ensure that bank account opening, tax registrations and accounting setups are aligned. A typical three-country parallel setup completes in 6 to 10 weeks.
What is the difference between BEPS, Pillar Two and CRS — and which apply to my business?
BEPS (Base Erosion and Profit Shifting) is the OECD's framework against tax avoidance through artificial profit shifting — it underpins transfer pricing rules. Pillar Two is the OECD's 15 percent global minimum tax that applies to multinational groups with consolidated revenue above EUR 750 million (so most SMEs are out of scope). CRS (Common Reporting Standard) is the automatic exchange of financial-account information between tax authorities — your bank reports your account to your tax authority. For most SMEs, BEPS-aligned transfer pricing and CRS reporting are the relevant items; Pillar Two becomes relevant only at the large-group level. We assess your specific exposure during onboarding.
How do you handle transfer pricing when our group has entities in multiple countries?
We follow the OECD Transfer Pricing Guidelines and the country-specific local-file requirements (India Form 3CEB, UK CbC report, UAE TP disclosures, Singapore TP documentation, USA Section 482, Hong Kong DIPN 59). For each related-party transaction — management fees, royalties, intercompany loans, cost-sharing — we benchmark using accepted databases and prepare a contemporaneous TP documentation pack. For SME groups we offer a streamlined TP package; for larger groups we coordinate with specialist TP partners.
Do you provide a single point of contact for multi-country engagements?
Yes — this is one of the most important things we do differently. Every multi-country client is assigned an Engagement Manager who owns the relationship across every jurisdiction. You email or WhatsApp one person, and they coordinate the underlying country teams. You never have to chase a UK accountant separately from a US bookkeeper separately from a UAE secretary. One engagement letter, one invoice, one point of accountability.
What is your turnaround time for new country registrations?
Typical turnaround: USA Delaware / Wyoming LLC or C-Corp — 5 to 10 working days from KYC to certificate. UK Limited Company — 1 to 3 working days via Companies House. UAE Mainland or Free Zone LLC — 7 to 21 working days depending on emirate and free zone. Singapore Private Limited — 1 to 5 working days via ACRA. Hong Kong Limited Company — 5 to 7 working days via Companies Registry. India Private Limited — 10 to 14 working days via MCA. Bank account opening typically adds 2 to 6 weeks depending on jurisdiction and KYC profile.
Do you provide ongoing compliance after the initial registration is complete?
Yes — registration is just day one. We provide ongoing monthly bookkeeping, quarterly VAT / GST / sales-tax filings, annual financial statements, statutory annual returns, payroll, transfer pricing documentation and audit support for every country we register an entity in. Most clients sign an annual retainer covering all jurisdictions, billed in monthly instalments. There is no obligation to take ongoing services after registration, but more than 80 percent of our incorporation clients do.
How do you ensure data security when handling sensitive cross-border financial data?
All client data is stored on encrypted cloud infrastructure with role-based access control. We sign a Non-Disclosure Agreement (NDA) before onboarding and operate under India's DPDP Act 2023, the UK / EU GDPR, Singapore's PDPA, Hong Kong's PDPO and the UAE's PDPL where applicable to client data. Bank statements, KYC documents and tax filings are exchanged only via password-protected portals — never plain email. Two-factor authentication is mandatory for every team member. Annual third-party security audits are performed on our infrastructure.
