Estimated Tax Worksheet - could it be any more complicated? (Don't Answer That)

Ok, going by the estimated tax worksheet, perhaps I owe a different amount for this quarter.

1. Adjusted gross income you expect in 2008:

(Adjusted gross income. Use your 2007 tax return and instructions as a guide to figuring out the adjusted gross income you expect in 2008. see Expected AGI -- Line 1 in chapter 2 of Pub. 505 -- "Your expected AGI for 2008 (line 1) is your expected total income minus your expected adjustments to income")

Let's just say $66,000 and forget any adjustments I might take.

2. Estimated total of itemized deductions: no idea

3. Subtract Line 2 from Line 1: $66,000

4. Exceptions: Multiply $3,500 by the number of personal exceptions = $0?

5. Subtract line 4 from line 3 = $66,000

6. Tax =
Figure your tax on amount on line 5 by using the 2008 Tax Rate Schedules on page 5. *If you have qualified dividends or a net capital gain, or expect to claim the foreign earned income exclusion or housing exlucsion, see "pub 505" to figure the tax.

  • 10% on income between $0 and $8,025
  • 15% on the income between $8,025 and $32,550; plus $802.50
  • 25% on the income between $32,550 and $78,850; plus $4,481.25 = $12843.755
  • 28% on the income between $78,850 and $164,550; plus $16,056.25
  • 33% on the income between $164,550 and $357,700; plus $40,052.25
  • 35% on the income over $357,700; plus $103,791.75
7. Alternative minimum tax from Form 6251: (this AMT confuses me to no end so for now I'm going to pretend it doesn't exist and hope it doesn't effect me.

What is the AMT? The AMT came into being with the Tax Reform Act of 1969. Its purpose was to target a small number of high-income taxpayers who could claim so many deductions they owed little or no income tax. A growing number of middle-income taxpayers are discovering they are subject to the AMT.

8. Add lines 6 & 7. Add to this amount any other taxes you expect to include in the total on Form 1040, line 44, or Form 1040A, line 28 = $12843.755

9. Credits (not not include any income tax withholding on this line): huh?

10. Subtract line 9 from line 8. If zero or less, enter 0 = $12843.755.

11. Self employment tax. Estimate of 2008 net earnings from self employment. (if $102,00 or less, multiply the amount by 15.3% -- Caution: If you also have wages subject to
social security tax, see Pub. 505 to figure the amount to enter) = $10,098

12. Other taxes (see instructions below): let's just say none.

13a. Add lines 10 through 12: $10,098
b. earned income credit (forms 4136, 8801 (line 27) and 8885) - None (you have to earn less than $17k for this.)
c. total 2008 estimated tax. Subtract line 13b from line 13a. If zero or less, enter 0 = $22,941.755

14a. multiply line 13c by 90% (unless you're a farmer or a fisherman, then it's 66.5%) = $20,647.58
b. enter the tax shown on your 2007 tax return (110% of that amount if you are not a farmer or a fisherman, and the adjusted gross income shown on that return is $150k or more) = no idea yet
c. required annual payment ot avoid a penalty. Enter the smaller of line 14a or 14b = $20,647.58

15. Income tax withheld and estimated to be withheld during 2008: none.

16a. subtract line 15 from line 14c:
Is the result zero or less?
Yes -- stop here. you don't have to pay anything.
No - go to line 16b...

16b: subtract line 15 from line 13c
is the result less than $1000
yes - stop. no money needed.
no - go to line 17 to figure your required payment

17. if the first payment you are required to make is due april 15, enter 1/4 of line 16a:
$20,647.58 / 4 = $5161.89

(but this doesn't at all include state taxes. I wonder if there is a separate quarterly estimated tax payment for that.)
