Sec 201

Dear Friend Amit,

Section 220 is applicable where pursuant to an order made by the AO (under various sections such as 143(3), 147 r.w.s. 143(3), etc.) a notice of demand is issued to the assessee u/s 156 and the assessee fails to pay tax as specified in such demand within a time limit (generally 30 days) specified in such demand. Further Section 221 reads as follows:

221. ⁸[(1) When an assessee is in default or is deemed to be in default in making a payment of tax, he shall, in addition to the amount of the arrears⁹ and the amount of interest payable under sub-section (2) of section 220, be liable, by way of penalty, to pay such amount as the ¹⁰[Assessing] Officer may direct¹¹, and in the case of a continuing default, such further amount or amounts as the ¹²[Assessing] Officer may, from time to time, direct, so, however, that the total amount of penalty does not exceed the amount of tax in arrears :

This means the penalty under this section is leviable if the assessee is deemed to be in default u/s 220(4) and not u/s 201(1A).

Futher the reason for deeming the assessee in default u/s 201(1A) is not to charge penalty but to initiate recovery against the assessee under various sections of income tax act by various modes such as attachment of movable or immovable property, arrest of assessee, etc.

Hope this will clear your doubt...
