Not filing or paying taxes on time can lead to penalties. Late payments may incur penalties of up to 25% of the outstanding tax amount.
Interest on unpaid taxes is charged at the federal short-term rate plus 3%.
There are also penalties for failure to pay estimated taxes if payments are underpaid or late.
These are broad recommendations, and individual situations may differ. Consulting with a tax professional or the Alabama Department of Revenue can help ensure compliance and provide personalized guidance based on individual or business needs.
