Alabama Form 40 Instructions

The Alabama Form 40 is an income tax return for Alabama residents. Read on this article to learn more about the form and its instructions.

If you are a non-resident of Alabama or only reside in the state for a portion of the year, you must complete and submit Alabama Form 40. This is a standard tax form that you will find available on the state’s website and in many local libraries and government offices. Alabama Form 40 Instructions are straightforward. The form must be filled out and submitted to the state of Alabama with your supporting documentation.

Almost all income is subject to state tax, including salaries, wages, bonuses, commissions, interest, dividends, rents, royalties, business or professional income, Alimony, estate and trust earnings, and other types of compensation. The following types of income are excluded from state income taxes: military pay, federal unemployment compensation, social security and spousal benefits, child support and other government payments, and charitable contributions.

Married couples filing jointly must report all their income, exemptions, deductions, and credits on this form. They must sign the return even if only one of them had any income during the tax year. Nonresident military personnel stationed at a duty station within Alabama and receiving Alabama-earned income may be exempt from state income tax by claiming the total allowable personal exemption on this form. On this form, they must also claim the credit for taxes paid to a foreign country.
