For Regular Tax purposes you are allowed a deduction for all state income taxes that you pay. If you are stuck in the Alternative Minimum Tax, however, you are allowed no deduction for state income taxes. This problem affects almost 100 percent of all individuals paying the Alternative Minimum Tax, so it is something that you definitely need to look into. This also represents one of the easiest AMT planning opportunities that you can do something about.
Overview
Every state that has an income tax requires that you pay your tax throughout the year. This can be done either through withholding from your paycheck if you are an employee, or through quarterly estimated payments if you are self-employed, retired, or have not adjusted your withholding to cover the additional taxes you will owe on your investment income.
Two key rules that apply to all states
1 – No state requires you to pay in 100% of your state tax liability – the required percentage generally is 80% or 90%. If you don’t pay in this required amount you may be subject to an underpayment penalty, which usually is calculated in a manner similar to interest.
2 – If you make quarterly estimated tax payments, the fourth quarter payment is generally due on January 15 – for example, January 15, 2011 for the fourth quarter installment of your 2010 taxes. This is the way the IRS works, and most states follow this pattern.
How to do this simple tax planning
The AMT-saving strategy here is to focus on the control you have over the payment of this last 10 or 20 percent you will owe, or, if applicable, your fourth quarter installment. Since you have the choice of paying this portion of your state income taxes in December or in January, the simple act of when you write out the check will have a direct impact on the AMT you will pay. As mentioned above, you get no benefit from a state income tax deduction in a year you are in the AMT. By putting more of your state income taxes paid in a year you are not in the Alternative Minimum Tax, you will achieve real tax savings.
Example
Assume that you are in the AMT in 2010, your total 2010 state taxes are $15,000, you will not be in the AMT in 2011, and your Regular Tax bracket is 35%. If you could defer paying $1,500 of your 2010 state income tax until January, this would save you over $500. If you could defer $3,000, your savings would be over $1,000. Note that even if you end in the AMT again next year, continuing to execute this strategy will mean that you will achieve this Regular Tax benefit in the first year that you are not in the AMT.
If you are certain that you will not be in the AMT next year, consideration might be given to delaying payment of more than the allowable percentage, even if it means incurring an underpayment penalty. The underpayment penalty for many states is at an interest rate of around 6% – incurring this small penalty obviously still will result in a lot more tax-savings cash in your pocket when you think about the Federal tax savings of up to 35%.
What you’ll need
If you do decide to pursue a state income tax strategy, first you will need to check the rules for making estimated payments for the state in which you live. All states have the necessary forms and related instructions that you will need available on their web sites.
The three key forms are each state’s equivalent of the following IRS forms:
- Form W-4, Employee’s Withholding Allowance Certificate – This can be filed at any time with your employer to adjust your withholding up or down.
- Form 1040-ES, Estimated Tax for Individuals – This is used to make quarterly estimated tax payments if you are self-employed or retired, or if you have not adjusted your withholding for the additional taxes due on your investment income.
- Form 2210, Underpayment of Estimated Tax by Individuals – This is used to determine whether you have paid in the required percentage. By reading the instructions you will see what your state’s required minimum pay-in percentage is.
Conclusion
Look at the potential cash benefit to you, as seen in the example above, from making this small investment of your time.
