Quick answer
Labs are equipment-heavy businesses — so depreciation, full expense claims, GST treatment and advance tax are the levers. Here's how.
Diagnostic and imaging equipment is expensive, and depreciation on it is one of your largest deductions. Some life-saving medical equipment attracts a higher depreciation rate. Claiming depreciation correctly each year significantly reduces taxable profit in an equipment-heavy business.
Lab turnover and equipment usually take you beyond presumptive, so keep books and deduct premises rent, technician and staff salaries, reagents and consumables, maintenance contracts, electricity, and financing interest on equipment. These are substantial and directly reduce taxable income.
Because depreciation starts once an asset is put to use, the timing of major equipment purchases affects your deduction. Planning significant capital purchases with the financial year-end in mind can bring forward depreciation benefits where it suits the business.
Diagnostic services have specific GST treatment, and you deduct TDS on certain payments. Getting GST registration and rates right, and handling your own TDS obligations, keeps you compliant and your expenses fully allowable.
On your personal return, use 80C, the Rs 50,000 NPS and 80D health insurance in the old regime. With no TDS on business income, pay advance tax in the four instalments if your tax exceeds Rs 10,000, to avoid 234B/234C interest.
Mainly through depreciation on expensive equipment and claiming all running costs — rent, staff, reagents, maintenance and financing interest — on actual books, which substantially reduces taxable profit.
General equipment attracts the standard rate, while some life-saving medical equipment qualifies for a higher depreciation rate. Claiming it correctly each year is a lab's largest deduction.
Usually books — lab turnover and equipment typically exceed the presumptive limits , and actual depreciation and expense claims produce lower taxable income than a flat rate.
