A registered freelancer can claim ITC only to the extent goods/services are used in the course or furtherance of business, subject to invoice, receipt, supplier-payment, return and blocked-credit rules. Personal use must be excluded.

Legal or Computational Framework

Governing rule

Section 16 creates entitlement; section 17 restricts personal/exempt use and blocks specified credits. Claiming depreciation on the GST component of capital goods prevents ITC on that component.

For the connected rule, example or next step, see GST ITC on Laptops, Mobiles and Office Equipment: Practical Guide for Indian SMEs.

Correct calculation method

Verify GST invoice/GSTIN; identify business use; exclude blocked credits; allocate common inputs; reconcile GSTR-2B; reverse personal/exempt proportion and 180-day non-payment where applicable.

Step-by-step workflow

Verify GST invoice/GSTIN.
identify business use.
exclude blocked credits.
allocate common inputs.
reconcile GSTR-2B.
reverse personal/exempt proportion and 180-day non-payment where applicable.

Worked example

Broadband GST ₹1,800 with documented 70% business use supports ₹1,260 provisional business allocation, subject to invoice and return conditions.

The example is an illustration, not a substitute for the taxpayer's facts. A change in status, period, payment mode, document, city, asset, relationship or scheme can change the result.

Why generic pages get this wrong

Search pages often state a rate or limit without identifying the governing base. The calculation must distinguish gross receipt from taxable profit, tax from TDS, a deduction from an exemption, salary from business income, and an accounting entry from the tax treatment.

Decision matrix

Decision point	Required treatment
Legal year	Use the Act, rules and notification effective for the income or transaction period
Taxpayer category	Confirm residence, age, entity, employee/business status and regime
Calculation base	Use the statutory definition rather than CTC, net bank receipt or accounting label
Ceiling or rate	Apply actual-amount, percentage, shared, lifetime and gross-income limits in sequence
Documentation	Link every input to an invoice, statement, contract, certificate or official record
Final output	Show tax, surcharge, cess, interest and TDS/TCS credits separately
