 Most of this information comes from the tax guide for small business for individuals who use Schedule C Publication 334 tax year 2022. You can find on the IRS website, irs.gov, irs.gov. Looking at the income tax formula, we're focused online, one that being income. Remembering that the first half of the income tax formula is in essence an income statement, although it's just an outline, a scaffolding, many other forms and schedules flowing into these line items. For example, with the income line we're focused on now, we're thinking about the Schedule C, another schedule, which is in essence an income statement in and of itself having income minus expenses or business deductions than net income, what flows through here to the income line item in our income tax formula. This formula representing the form 1040, this is the first page of the form 1040 where we would be focusing in on line eight, other income from Schedule One. The income would flow through the Schedule C to Schedule One to here to line eight on page one of the 1040. Here is a Schedule C profit or loss from business where we would have income minus expenses, the net income flowing to Schedule One, flowing the page one of the 1040. Okay, identification numbers. As we know, the IRS knows us not by name, but by number. So we need to have one of those things. So this section explains three types of taxpayer identification numbers. We got the TINs, who needs them, when to use them, and how to get them. So social security numbers, the SSN, this is the major obviously number for individuals. Now the individual social security number, if you have one, could be used for filing obviously the form 1040 and possibly for your business as well. But even if you don't have any employees, you may still want to get another number, which might be an EIN number. One reason you might want to do that is because if you work for other businesses, then you might have to provide those other businesses with your identification information so they can issue you not a W2, but a 1099. And you don't wanna have to issue or give them your social security number. So you might then wanna set up an EIN number in that instance, which is fairly easy to do and we might touch on in a second here in a bit more. So generally you use an SSN social security number or TIN. You must put this number on each of your individual income tax forms, such as the form 1040 and its schedules. To apply for an SSN social security number, use form SS-5 application for a social security card. This form is available at Social Security Administration, the SSA offices, or by calling 800-772-1213. So that is a separate institution. Of course it's a federally federal government institution, but sometimes people think that all federal government institutions are like the same or that all governments are the same, like the federal government versus the state and local government. And although they could exchange information, you have to part of the art of dealing with the government is go into the right place to do the right thing. So if we wanna get the social security number, which we will need to tell the IRS who we are, we've gotta go to the Social Security Administration and deal with them at the SSA. So it is also available from the SSA website, which you can go to ssa.gov forward slash forms forward slash SS-5. Individual taxpayer identification number, otherwise known as an ITIN, the IRS will issue an ITIN if you are a non-resident or resident alien and you do not have and are not eligible to get an SSN, a social security number. So the social security number for individual reporting is basically the default number that you would put on the 1040, but if you don't have the social security number of social security numbers, the IRS still wants to know who you are and they still wanna get a piece of your income if it's subject to income. So then you've got the fallback number for individual taxpayers being the ITIN. So the ITIN will expire for any taxpayer who does not file a federal income tax return or who has not included as a dependent on the return of another taxpayer for three consecutive years. It's a temporary thing. You gotta keep it in constant update. So in general, if you need to obtain an ITIN, you must attach form W7 application for IRS individual taxpayer identification number with your signature, original completed tax return and any other required documentation and mail them to the address in the instructions for form W7. So you can take a look at the IRS website, get the instructions for the W7 if you need more information on that. Exceptions are covered in the instructions. So if you must include another person's SSN, social security number on your return and that person does not have and cannot get an SSN, enter that person's ITIN. Another person on your 1040, for example, could be a spouse, could be a dependent. So the application is also available in Spanish, Spanish, the form is available at irs.gov forward slash form W7 caution and ITIN is for tax use only. It does not entitle the holder to social security benefits or change the holder's employment or immigration status. Immigration. So the IRS needs that number to process the income tax return. One of the problems if you're working in a situation where you don't have a social security number or access to social security benefits is one of the issues. Are you gonna be subject to paying social security taxes in a situation where you're not gonna get the benefits of the social security benefits after the age of retirement? But we won't dive into that.
