Tax Deduction

Categories: Tax

Taxes. Love ‘em. Hate ‘em. You can’t leave ‘em. But you can lower ‘em. Legally. By being thoughtful about how you spend your earnings.

Let’s start with the largest tax deduction in America: the home mortgage. And you. You...the dentist who makes 150 grand a year. Remember that for individuals (vs corporations), we pay a graduated or "progressive" tax rate, like…almost nothing on the first $15k we earn, then about 10 percent from $15k to $30k, and then about 20 percent from $30k to $60k, and so on. So, on the last 20 grand of earnings you make, you might pay, say, 40 percent in taxes. And yeah, we know the numbers aren’t exact. We’re just illustrating a point here.

You have a mortgage of $300,000 on a home you bought for $400,000. The mortgage costs you 6% per year in interest, or $18,000. Before you owned the home, the IRS thought of you as a 150-grand-a-year earner. But 100% of the interest on the mortgage is fully tax-deductible.

So what about that last 20 grand, i.e. the money you earned from $130k to $150k? Well, as far as the IRS is concerned, you get taxed as if you earned just 132 grand, not the 150k you actually earned. Why? Because that $18k comes right off the top of your earnings. As if you didn’t earn that money. If you’d had no deductions, on that last 20k of earnings, you’d have paid 40%, or $8,000 in taxes. But now, on that last $20k, thanks to your mortgage deduction, you only have taxable income of $2k. And yes, you pay 40% on that $2k, or 800 bucks. And you mumble, "Thank you, government, for largely splitting the cost of my mortgage with me. The American Dream is alive and well."

There are other deductions beyond home mortgages, of course, but you get the gist. From a taxpayer's perspective, deductions like those from home mortgages are a good thing, and this is how they work. Common personal deductions also include things like prepaid health care costs and the cost of feeding dependent children, i.e. those noisy things sleeping in your spare bedrooms until they're 18.

Okay, so those are personal deductions: things that individual citizens take. But what if you‘re a corporation? Well, it’s kinda easier. Think of most corporations as having a flat 30 percent tax from the first dollar they make, just to keep things simple. Participation Trophy Company, Inc. made $100 million last year and paid $30 mil in taxes. They netted $70 million after tax. The company really needs a new trophy smelting machine, because with so much demand for participation trophies of late, the old one is running…dull.

The company spends $40 million on the new machine, knowing that it’ll be worthless in 10 years, either because it wears out, or because the country gets real, or simply remembers to...have a nice day. They depreciate the $40 million in equal parts of $4 million each year over ten years, so that in the next year, when they again earn $100 million, they now get to deduct $4 million in depreciation from their smelting machine against their $100 million in earnings.

So again, as far as the IRS is concerned, they didn’t earn $100 million. They earned "only" $96 million. And they still pay their 30% tax, only now instead of being on $100 million, it’s on $96 million of earnings, or 0.3 times 96, or $28.8 million in taxes. They deducted from their taxes the $4 million in expected value decline from their smelting machine, but received essentially a credit on their taxes of $1.2 million.

So instead of that year’s depreciation costing the company 4 million bucks, it really costs them more like $2.8 million, if you ignore a bunch of other things, like the original capital cost of the machine, and what else they might have done with that money other than buy a smelting machine.

Think...corporate jet: Those G6s are surprisingly tasteful.

00:35

unquote tax rate Like almost nothing On the first fifteen

00:39

grand we earned on about ten percent from fifteen to

00:42

thirty grand And then about twenty percent from thirty to

00:47

last twenty grand of earnings you make well you might

00:50

pay say forty percent in taxes and yeah we know

00:53

the numbers own exact We're just illustrating a point Here

00:56

you have a mortgage of three hundred thousand dollars on

00:58

a home you bought for four hundred thousand dollars right

01:01

So you put a hundred grand down and borrow three

01:03

hundred The mortgage costs you six percent per year in

01:06

interest or eighteen thousand dollars to rent that three hundred

01:09

thousand before you owned the home The irs thought of

01:13

you as one hundred fifty grand a year earner but

01:16

one hundred percent of the interest on the home is

01:19

fully tax deductible So what about that last twenty grand

01:23

iii The money you earn from one hundred thirty k

01:26

to one hundred fifty k Well as faras the irs

01:29

is concerned now that you have a home you get

01:31

taxed as if you earned just one hundred thirty two

01:35

grand not one hundred fifty k actually earned Why Because

01:39

that eighteen thousand dollars in interest comes right off the

01:43

top of your earnings See there's the math right there

01:46

one hundred fifty minutes eighteen hundred thirty two taxable earnings

01:48

it's as if you didn't earn that money ever can't

01:55

all right well if you'd had no deductions on that

01:57

last twenty thousand dollars of earnings you'd have paid forty

02:00

percent or eight thousand dollars in taxes But now on

02:04

that last twenty thousand dollars thanks to your mortgage deduction

02:07

well you only have taxable income of two thousand dollars

02:11

And yes you pay forty percent on that two thousand

02:14

Or eight hundred bucks And you mumbled thank you government

02:17

for largely splitting the cost of my mortgage with me

02:20

The american dream is alive and well that's what you

02:23

say Okay And thank you jay There are other deductions

02:26

beyond home mortgages of course but well you get the

02:29

gist here of how they work from a taxpayer's perspective

02:33

Deductions like those from your home mortgages are a good

02:36

thing Common personal deductions also include things like prepaid healthcare

02:41

costs and the cost of feeding quote dependent unquote children

02:45

Aii those noisy things sleeping in your spare bedrooms until

02:49

they're eighteen Okay so those air personal deductions things that

02:52

individual citizens take But what if you're a corporation Well

02:56

in a way it's kind of easier Think of most

02:58

corporations is having a flat thirty percent tax from the

03:01

first dollar they make just keep things simple Participation trophy

03:04

company in kameda one hundred million dollars last year and

03:08

paid thirty million in taxes They netted seventy million after

03:12

tax The company really needs a new trophy smelting machine

03:16

because with so much demand for participation trophies of late

03:20

while the old one is running dullah with mediocrity the

03:24

company spends forty million box on the new machine knowing

03:27

that it will be worthless in ten years either because

03:30

it wears out or because the country gets riel or

03:33

you know simply remembers to you know have a nice

03:35

day participation trophy land Welcome to it They'd appreciate forty

03:39

million dollars in equal parts of four million box each

03:42

year over ten years so that in the next year

03:45

when they again or in one hundred million dollars well

03:47

they now get to deduct four million bucks and appreciation

03:51

from their smelting machine against their hundred million dollars in

03:55

earnings So again as faras the irs is concerned they

03:58

didn't really earn one hundred million dollars even though they

04:00

did They earned quote on ly unquote ninety six million

04:04

and yes they still pay their thirty percent tax Only

04:07

now instead of paying it on a hundred million bucks

04:09

it's paid on ninety six million of earnings or point

04:13

three times ninety six or twenty eight point eight million

04:17

in taxes they did Abducted from their taxes The four

04:21

million box expected value decline from their smelting machine Right

04:25

It goes down four million a year in value from

04:27

the forty they paid They received essentially a credit on

04:30

their taxes of one point two million dollars So instead

04:34

of that year's depreciation costing the company four million bucks

04:38

well it really cost them more like two point eight

04:41

million If you ignore a bunch of other things like

04:42

the original capital cost of the machine what else they

04:45

might have done with that money oven you know via

04:48

smelting machine Think think Corporate jet Yeah those g sixes 00:04:52.774 --> [endTime] are surprisingly tasteful
