40% Depreciation

Ohhk thanks a lot Poornima Mam & saurav sir

It should charged to p&l since we usually buy only a yearly license

Yearly renewal cannot be done without buying the software initially.

Does the license agreement stipulate two sets of payment i.e., initial software purchase and yearly renewals?
if so, what part of the initial cost is attributable to usage fee for the first year. such amount must be brought to p&l. only that part which is for one time fee for obtaining software should be depreciated

Yes you're right.

If its a yearly subscripttion you can charge it P&L. You may also calculate prorata and put some amount in prepaid if required.
