ITR form suggestion

Since you have only salary income during the year but wish to continue reporting the brought-forward business losses, you should file ITR-2. ITR-1 cannot be used as it does not provide for reporting carried-forward losses. The brought-forward business loss cannot be set off against salary income and can be adjusted only against eligible business income arising within the permissible carry-forward period of 8 assessment years.

The right ITR form is determined by the nature of the income and the taxpayer's position, rather than the quantity of income.

ITR-1 (Sahaj): For resident individuals with salary/pension income, income from house property, and other sources, subject to the prescribed conditions. 

ITR-2: For individuals/HUFs with capital gains, multiple house properties, foreign assets/income, etc., but no business or professional income. 

ITR-3: For individuals/HUFs with business or professional income, including freelancing, consultancy, commission, brokerage, or proprietorship bus

ITR-4 (Sugam): For qualified taxpayers who choose presumptive taxation under sections 44AD, 44ADA, or 44AE, subject to eligibility requirements.
Please provide your income sources (salary, capital gains, business/professional income, home property income, etc.), residence status, and if you want presumptive taxes. Based on these facts, the suitable ITR form may be appropriately recommended.
