International Accounting by Jurisdictions
Estonia Accounting Services
Smart Financial Support for Europe’s Top Digital Hub
Estonia’s famous digital-first setup makes running a business incredibly smooth. If you have launched an Estonian company—especially through the e-Residency program—you need an accounting team that truly understands Estonia’s unique tax landscape.
What makes Estonian accounting different?
Estonia uses a brilliant corporate tax system where reinvested profits are taxed at 0%. You only pay a 22% corporate tax rate when you choose to take money out as dividends. This gives you a massive advantage to reinvest your cash and grow your brand, but it also means your daily bookkeeping must clearly track your saved versus paid-out profits.
Our Estonia accounting plans include:
Daily Bookkeeping: Financial records built to match exact Estonian accounting laws.
Commercial Register Filings: Smooth preparation and submission of your annual reports.
Monthly Tax Declarations: Filing your required corporate tax forms (even when you owe $0).
VAT Setup & Returns: Fast VAT registration and regular filings for your European sales.
Global Payroll Support: Accurate pay processing for your local and international team members.
E-Invoicing Tools: Setting up and managing automated digital invoicing.
Owner Transparency Filings: Handling mandatory UBO (Ultimate Beneficial Owner) declarations.
Tax Office Liaison: Speaking directly with Estonian tax authorities whenever questions pop up.
⚠️ Critical Deadline: Estonian companies must submit their annual reports by June 30th every year. We ensure your paperwork is flawless and filed on time so your business stays in perfect standing.
Лучшее для: SaaS brands, e-commerce sellers, digital agencies, and remote-first founders running a global business through Europe.
UK Accounting Services
Stay Safe with Companies House and HMRC
UK accounting follows strict standards. Staying legal means understanding Companies House rules, HMRC tax duties, and proper year-end paperwork.
What makes UK accounting different?
UK companies must file two different types of paperwork: annual accounts with Companies House (for the public record) and separate tax returns with HMRC. Because these two agencies use completely different deadlines and formats—and charge heavy fines for being late—professional accounting support is a must.
Our UK accounting plans include:
Daily Bookkeeping: Monthly management accounts to track your exact cash flow.
Annual Accounts: Statutory paperwork prepared perfectly for Companies House.
Corporate Tax Returns: Error-free CT600 tax forms submitted straight to HMRC.
Digital VAT Setup: Fast VAT registration and MTD-compliant digital tax returns.
Global Payroll Services: Complete management for your team, including PAYE, National Insurance, and real-time filings.
Construction Scheme (CIS): Full compliance tracking for building and trade industries.
Confirmation Statements: Verifying your official company details with the government on time.
Smart Tax Planning: Professional guidance for maximizing your R&D tax credit claims.
💰 Tax & Deadlines Check: UK Corporation Tax ranges from 19% to 25% depending on your profits. Companies House requires your accounts within 9 months of your year-end, while HMRC gives you 12 months for your tax return. We manage both deadlines seamlessly to protect your cash.
Лучшее для: Trading companies, consulting agencies, online e-commerce stores, and brands needing a solid UK presence for European market access.
Hong Kong Accounting Services
Maximize the Power of a Zero-Tax Setup
Hong Kong uses a famous “territorial” tax setup. This creates incredible financial opportunities, but only if your accounts are structured correctly and backed by rock-solid evidence.
What makes Hong Kong accounting different?
In Hong Kong, only profits earned locally are taxed. Money earned outside of Hong Kong is completely tax-exempt! However, proving to the government that your income is truly “offshore” requires perfect documentation—including your contracts, invoices, and daily operational files. Our systems are built to back up your tax-free claims flawlessly.
Our Hong Kong accounting plans include:
Ежемесячное ведение бухгалтерского учета: Flawless financial statements built to match local rules.
Profits Tax Returns: Expert filings equipped with official offshore tax-exemption claims.
Audit Coordination: Full preparation and management for your mandatory annual audits.
Employer Tax Returns: Complete payroll reporting and official staff filings.
Business License Renewals: Keeping your Business Registration Certificate active and legal.
Annual Returns: Filing your mandatory yearly updates with the Companies Registry.
Transfer Pricing Records: Safe legal tracking for deals made between your related corporate branches.
Substance Proofs: Gathering the exact paperwork needed to secure your tax-free offshore status.
💰 Tax & Deadlines Check: Hong Kong Profits Tax is just 8.25% on your first HKD 2 million, and 16.5% after that—but remember, this is only on money made inside Hong Kong. An independent audit is required for almost all companies, and we partner with top local CPA firms to make the process completely stress-free.
Лучшее для: E-commerce sellers, cross-border traders, holding companies, IP licensing brands, and businesses serving international clients from Asia.
Portugal Accounting Services
Favorable European Tax Rules with Certified Local Support
Portugal is one of the most popular countries in Europe for relocating entrepreneurs—especially with its famous personal tax perks. Portuguese accounting seamlessly combines standard European rules with strict local laws.
What makes Portuguese accounting different?
Portugal legally requires a locally certified accountant (Contabilista Certificado) to manage and sign off on your business finances. Every single financial entry must be submitted digitally through the government’s online tax portal, backed by incredibly strict documentation.
Our Portugal accounting plans include:
Certified Bookkeeping: Monthly records managed by licensed Portuguese accountants.

💰 Tax & Decoded Perks: The standard Portuguese corporate tax rate is 19% in 2026. However, qualifying small and medium businesses enjoy a reduced 15% rate on their first €50,000 in profits. Portugal’s booming startup scene makes it the ultimate European hub for founders wanting top-tier personal tax treatment.
Лучшее для: Relocating entrepreneurs, tech startups, digital nomads building an EU base, and brands targeting Portuguese-speaking global markets.
UAE Accounting Services
Secure Your Zero-Tax Status in a Booming Global Hub
The United Arab Emirates is a massive magnet for global founders thanks to its incredible low-tax setups. However, with the introduction of corporate tax rules and strict economic substance checks, professional accounting is now more vital than ever.
What makes UAE accounting different?
If you launch your company inside an official “Free Zone,” you can completely lock in a 0% tax status—but only if you follow specific operational rules. Businesses registered on the “Mainland” pay a 9% corporate tax on all profits that cross over AED 375,000. Proper bookkeeping is the only way to prove where your money belongs.
Our UAE accounting plans include:
Dual-Zone Bookkeeping: Monthly record-keeping for both Free Zone and Mainland companies.
Corporate Tax Registration: Setting up your tax profile and filing your required returns.
VAT Management: Complete sales tax registration and quarterly filings at the 5% standard rate.

Financial Auditing: Certified audit support for businesses that cross government sales limits.
Transfer Pricing Logs: Safe, legal tracking for deals made between your related branches.
Owner Transparency Forms: Filing mandatory Ultimate Beneficial Owner (UBO) declarations.
Local Compliance Checks: Seamless coordination with modern UAE accounting standards.
💰 Tax & Decoded Perks: While corporate tax is active in the UAE, Free Zone brands can safely enjoy a Налоговая ставка 0% by hitting qualifying conditions from day one. Additionally, VAT registration is mandatory once your sales cross AED 375,000, though many global brands register early to legally claw back their setup costs.
Лучшее для: E-commerce stores, international trading firms, remote consultants, corporate holding setups, and brands targeting Middle Eastern and African markets.
