THAT is the best post on this thread. Heed the advice!
As for deductions, let me try to make it simple, since so very many otherwise intelligent people seem to go into mental vaporlock and get confused on this, even though it's really pretty simple.
Tax deductions reduce the amount of tax you pay. They DON'T put money in your pocket. If you are at a 15% tax rate, and you find a $1,000 deduction, you reduce the tax you owe by 15% of $1,000, or $150. So if you had to spend that $1,000 anyway , and you can deduct it, great. You saved $150. But if you go out and deliberately SPEND $1,000 to get that deduction, you just spent $850 that you didn't need to spend! You paid out $1,000, and got back $150 of it.
Hey, for anybody who thinks that's a good deal, I've got a better one for you. You send ME the $1,000, and I'll send you back HALF of it! That's even better! You pay out $1,000, and get back $500! I'll take as many of those deals as I can find! No limits! Any amount! As often as you want! Call now! Operators are standing by!
Taking deductions on money you were going to spend anyway reduces your tax bill. SPENDING money unnecessarily to CREATE deductions makes you poor.
Period. Well, with one exception:
You are just above the threshold of a tax bracket. Let's say, $150 over, so your tax rate is 20%. You spend $200 on a legitimate business expense, and you drop into the 15% bracket. The tax you NOW owe is $500 less than if you did not have that deduction. You NET $300. That's good, but that takes very careful accounting and planning, and you won't know if you need to do it until you have run the numbers for the year.
The only other way that tax deductions can make money is to take items that USED to be personal expenses, and 'convert' them to deductible business expenses. This can be legitimate in some circumstances, and often gotten away with in some circumstances.
Usually is just plain fraud.
I'm always amazed at how many people think the IRS doesn't see the same scams all the time. The only thing that keeps a lot of people out of serious trouble is lack of investigative and prosecution resources.
