As a self-employed individual, you are required to pay
1099 tax on any income you earn if it exceeds $400 a year. As the American tax system works on a “pay as you go” basis, this tax payment might be split over four quarters if you think you’ll owe the IRS over $1,000.
You can use a
quarterly tax payment calculator to check whether you’ll need to make estimated quarterly payments. But sometimes, deadlines are forgotten or you’re just not able to get the money together. So with the help of a
tax penalty calculator, you can calculate your tax penalties and get back on track.
Now, to calculate the home office tax deduction, the IRS gives you two options. The first option is the newer,
simplified method that requires minimal calculation. To claim this, you just need to total the square footage of your home office and multiply it by $5.
So, a 170 square feet square home office gets a $850 deduction. However, a big office doesn’t necessarily mean a bigger deduction. The IRS caps the claim at 300 square feet or $1,500. If you’re using this method, you can just report the deduction on
Schedule C (part of
Form 1040).
The other option is the standard home office deduction which involves a lot more calculations. You’ll first need to total all your home office expenses and multiply it by your business use percentage.
If your home office is 100 square feet, and you live in an apartment that is 1,500 square feet, that’s an approximate business use percentage of 6.67% (100/1,500 x 100). You can then deduct the business-related portion of other expenses related to your office like
mortgage interest, utilities and furniture.
