A freelancer offering US mortgage-related services, with TDS deducted under Section 194J and income under 5 lakhs, is seeking clarification on whether to declare income under Section 44AD or 44ADA. The issue arises because the appropriate business code (16019 - other professional services) is listed under 44AD, not 44ADA. The freelancer is considering using code 16005 (engineering & technical consultancy) which is available under 44ADA, by treating their services as technical consultancy.
