DDTC

What DDTC does

DDTC is an Indonesian research-based tax consulting firm founded in 2007 and headquartered in Jakarta, with a secondary office in Surabaya. The firm delivers professional tax services covering consultation, compliance, litigation, and transfer pricing primarily to corporate clients operating in Indonesia's domestic and international tax landscape. Founded by Darussalam and Danny Septriadi, DDTC positions itself as a knowledge-driven institution rather than a traditional advisory practice, with Darussalam serving as Managing Partner and also chairing Atpetsi, the Indonesian university tax center association.

The company's product portfolio consists of six interconnected platforms: DDTC Consulting (core advisory services), DDTC Fiscal Research & Advisory (policy analysis and strategic recommendations), DDTC Academy (online professional training and courses), DDTCNews (tax news and analysis portal), Perpajakan DDTC (subscription-based web tax database aggregating central regulations, tax court decisions, P3B treaties, and consolidated tax law), and DDTC Library (a digital and physical library of more than 4,700 tax publications described as the most comprehensive in Indonesia). The technology stack is primarily content management and information delivery, with no disclosed AI/ML capabilities, APIs, or third-party integrations.

DDTC generates revenue through a combination of professional services fees (consulting, fiscal research, training) and recurring subscription revenue (Perpajakan DDTC database access), with no publicly disclosed pricing. Distribution is direct-to-enterprise for consulting and self-serve online for academy, database, and library products. The firm has established education cooperation agreements with 24 Indonesian universities, embedding it in the academic talent pipeline. It holds International Tax Review Top Tier Firm recognition for World Tax 2026 along with multiple category awards (Transfer Pricing Firm of the Year 2024, Tax Disputes 2024, Pro Bono 2022) and has received formal recognition from Indonesia's Directorate General of Taxes (DJP) at both headquarters and regional office levels.
