Navigating the complexities of Goods and Services Tax requires both technical understanding and ongoing regulatory vigilance. CASTP provides comprehensive GST compliance and advisory services, from registration and monthly filings to dispute resolution and representation before tax authorities.
We help businesses reduce GST risk, claim accurate input tax credits, and maintain clean compliance records throughout the year.


Effective tax management goes beyond filing returns — it demands strategic planning, precise compliance, and proactive advisory. CASTP offers structured direct taxation services covering individual, corporate, and trust entities, ensuring optimal tax outcomes within the framework of Indian law.
Our team stays current with amendments to the Income Tax Act, enabling us to provide timely, accurate, and commercially viable tax guidance.
Sound financial decision-making begins with accurate records. Our accounting and bookkeeping services ensure your books are maintained to the highest standard — giving management real-time visibility into financial performance and keeping businesses audit-ready at all times.
We work with businesses across sectors, providing both on-site and remote bookkeeping support tailored to your operational rhythm and reporting requirements.


Regulatory compliance is no longer optional, it is a fundamental business requirement. CASTP provides end-to-end statutory compliance support, ensuring your business meets all legal obligations under the Companies Act, ROC regulations, FEMA, and applicable labour laws.
We monitor compliance calendars, file statutory returns on time, and proactively alert clients to legislative changes that may affect their business.
Beyond compliance, businesses need structured financial thinking to grow sustainably. CASTP offers practical financial consultancy services, from business planning and cash flow analysis to financial restructuring and transaction support, helping decision-makers navigate complexity with clarity.
Our consultancy approach is grounded in real-world business understanding, not just theoretical frameworks. We speak the language of your balance sheet and your boardroom.
