One shortcoming of the articles of confederation was that it did not provide for:
equal voting rights
american independence
election of representatives
collection of taxes

Collection of taxes

Explanation:

The Articles of Confederation was the first US Constitution but had a few problems that caused the creation of the current Constitution.

One of those problems was the creation of taxes. The Articles of Confederation created a national government composed of a Congress, but the states did not want to lose power and form a strong central government, because of that the Congress had a few powers such as declare wars, appoint military officers, sign treaties, make alliances, appoint foreign ambassadors and manage relations with Indians.

But the Congress did not have the power to tax, the Congress and central power would raise money by asking the states for funds, borrowing from foreign governments or selling lands. This caused many problems because states did not fund the federal government enough, causing a weak central government and this led to the failure of a quorum to ratify the treaty that guaranteed American Independence.
