Accounting in Iceland is shaped by a short list of firms that audit most of the country’s listed companies, banks and municipalities, plus a long tail of smaller bookkeeping offices that handle VAT, payroll and annual accounts for small and mid sized businesses. Compliance is frequent: according to Iceland Revenue and Customs (Skatturinn), the standard VAT rate is 24%, the reduced rate is 11%, and most businesses file every two months, with payment due one month and five days after each period ends.
For foreign owned companies the practical questions are who can register a branch or subsidiary, run Icelandic payroll with pension fund and union filings, and produce accounts that satisfy both Skatturinn and a parent company abroad. The firms below include the Big Four Icelandic member firms, mid tier audit practices with international network membership, and specialist bookkeeping and payroll providers.
For this list we checked each company on its own website for an Iceland office address, accounting, audit or bookkeeping as a core service and named client work. No company paid to be included, and the order reflects our judgement of strength and fit. For more Iceland lists and guides, visit our Iceland hub.

Sigurbergsson as managing and international practice partner.
The firm’s own site lists four service areas: financial advisory, tax advisory, accounting and financial statements, and audit. As part of the Grant Thornton International network it can coordinate with member firms abroad on group audits and cross border tax.
Grant Thornton suits mid sized Icelandic companies and foreign groups that want a partner led firm with an international network but a smaller team than the Big Four.

It reports more than 800 clients and over 10,000 completed projects. Its team includes account managers, a payroll department and accredited bookkeepers.
Fastland suits Icelandic small businesses and foreign founders with a local company who want a dedicated account manager rather than an audit firm. Its site is in Icelandic only, so check English support before signing.

Services include bookkeeping, payroll and year end closing with tax returns, tax advice on business structures, company formation and dissolution and disputes with the tax authorities, financial statements under Icelandic and international standards, and audit, due diligence and internal control reviews.

Íslenskir endurskoðendur (Icelandic Auditors) is based at Bæjarhraun 8, 220 Hafnarfjörður, and has auditors working in different parts of Iceland. It positions itself as an alternative option for auditing Icelandic companies of different sizes.
News on its site records an audit contract with the Association of Municipalities in Suðurnes, won through a tender, and membership of a Ríkiskaup framework agreement for audit services alongside 11 other Icelandic firms. The site has an English section.
Íslenskir endurskoðendur suits municipalities, regional companies and mid sized firms that want a domestic audit partner outside the large international networks.
Bóklega is a bookkeeping and tax advisory office at Sundaborg 5, 104 Reykjavík, serving small and medium sized businesses in the capital area.
Its bookkeeping service covers bank entries and reconciliations, VAT returns, payroll and financial reports. Annual accounts work includes preparation and filing with Skatturinn and compliance checks. Advisory services cover operations, tax planning, company formation and choosing an accounting system. Bóklega names contractors, startups, shops, restaurants and consultants as typical clients, and says a bookkeeper reviews entries and is responsible for decisions.
Bóklega suits new companies and small foreign owned startups in Reykjavík that need affordable, hands on bookkeeping. The site offers an English language link.
Larger companies above the statutory thresholds and listed companies need an external auditor, which is where KPMG, Deloitte, PwC, Grant Thornton, Enor, DFK and Íslenskir endurskoðendur come in. Many small private companies only need bookkeeping, VAT, payroll and annual accounts, which offices such as Fastland, Virtus and Bóklega handle. Some firms do both.
Icelandic is the language of filings and most firm websites, but international firms and those with foreign clients usually work in English. Enor, Virtus and DFK all describe services for foreign parties. Ask for the name of the English speaking account manager and whether monthly reports can be delivered in English.
A foreign company can register a branch or form an Icelandic subsidiary. Skatturinn”s branch registration guidance asks for an Icelandic address, a branch manager, a recent certificate of registration and the parent’s latest annual accounts, with processing generally taking two to three weeks. An accountant can prepare the forms and register the business for VAT and payroll.
Standard VAT periods are two months long, with payment due one month and five days after each period. Businesses with taxable sales of ISK 2 million or less in a twelve month period are exempt from VAT registration. Payroll is filed monthly, including withholding tax and contributions to pension funds and unions, so pick a firm with a reliable payroll team.
Fees are quoted in ISK, usually as a monthly bookkeeping fee plus hourly rates for annual accounts, tax and audit. Ask for a fixed monthly price covering VAT returns and payroll for a set number of employees, and a separate quote for year end work so there are no surprises.
Iceland’s accounting market splits into international audit firms, mid tier practices and focused bookkeeping offices. KPMG, Deloitte and PwC offer the deepest audit and advisory benches, Enor, Grant Thornton and DFK combine audit with international networks, and Virtus, Fastland and Bóklega cover day to day bookkeeping and payroll.
Foreign owned companies should prioritise firms that already handle foreign entity registration and Icelandic payroll in English, then confirm who will sign the accounts, how VAT periods are managed and what the monthly ISK fee includes.
