Self employed as IT consultant and as massage therapist: Do I need 2 HST numbers?
Given your clarifying points, it sounds like you are running both businesses as one combined business. As such, you should be able to get just a single HST number and use that. However, let me please urge you to contact a professional accountant and possibly a lawyer, as it is very unusual to be performing these services without a business license, and you may be exposing yourself to civil penalties and placing your personal assets (e.g. your house) at risk. Additionally, it may be beneficial for you to run these as businesses as you can likely write off (more of) your expenses.
First off, the basics on HST/GST:   You don't need to collect HST, if you don't want to, until you hit 30k in a particular three month period (assuming you're not regularly passing $30k).  You then need to collect on the sale that takes you over $30k plus all sales after that.  See the H&R Block page on GST/HST for example: [B]usiness goes through the roof, generating more than $30,000 in one particular three-month period. In this case, the day the sale goes through that took you over that $30,000 threshold becomes the day you cease to be a small supplier. You must charge GST/HST on the sale that put you over the $30,000 limit, and on all sales after that, even if you are not yet registered. You now have 29 days to register with the government. Alternately, if you hit 30k over four three-month periods (i.e., a year), then you are exempt until the end of that fourth three-month period, after which you must register and collect HST the month after: [R]evenues in excess of $30,000 during four (or fewer) previous, consecutive three-month periods. You will be considered to be a small supplier for those four calendar three-month periods, plus the next month. Your first sale after that additional month, and all sales thereafter, will have to include GST/HST. You will have 29 days from the first day of the second month to register. However, many businesses do collect HST/GST even under that limit, in particular as it means you can collect tax refunds for your input HST/GST paid.  If you do so, then you simply register from the start, and then you don't need to worry about it.  You do need to remit those taxes collected, though.  If you don't remit, you won't be able to collect tax rebates for your input HST/GST. You decide to become a GST/HST registrant when you start your business. You expect to exceed the $30,000 threshold at some time in the near future. You also want to receive any GST/HST paid back from the government on all expenditures especially those high startup costs. And, as Grant Thornton recommends: In most cases, it’s generally a good idea to register for GST/HST as soon as your business is established. Provided that your business makes (or will make) taxable or zero-rated supplies, early registration ensures that GST/HST paid on costs incurred is recoverable since tax paid prior to registration is generally not recoverable except on the purchase of inventory, capital property and prepaid services still on hand at the time of registration. Be sure to register early because, in many situations, registering late can result in the loss of recoverable GST paid before registration. Do I get a write off for paying student loans? Maybe.  See https://www.irs.gov/publications/p970/ch04.html Generally, personal interest you pay, other than certain mortgage interest, isn't deductible on your tax return. However, if your modified adjusted gross income (MAGI) is less than $80,000 ($160,000 if filing a joint return) there is a special deduction allowed for paying interest on a student loan (also known as an education loan) used for higher education. For most taxpayers, MAGI is the adjusted gross income as figured on their federal income tax return before subtracting any deduction for student loan interest. This deduction can reduce the amount of your income subject to tax by up to $2,500.  Read the whole document to be sure, but that's the basics.   You'll have to fill out a 1040 or 1040A to claim a student loan deduction.  It won't be on the 1040EZ.  You do not have to itemize though.   What kinds of write-offs and credits are available for someone who is single and lives in an apartment with two roommates? As a practical matter, in 2016 you'll get the standard deduction for someone who is single ($6300) and the personal exemption ($4050).  It's extremely unlikely that you'll be able to deduct more by itemizing.  Most people who itemize are taking a mortgage interest deduction.  Major medical bills are another possibility, but they have to be more than 10% of your adjusted gross income (it's one of the lines on your tax return).  Assuming you rent and are reasonably healthy, you are unlikely to have enough to itemize.   The most likely additional deduction would be the one for an IRA (Individual Retirement Account).  Although you might be better off doing a Roth anyway (no tax deduction).   If you are self-employed or making more than $100,000 a year, there are additional issues.  But most people aren't.  If you filled out a W-4 and will get a W-2 back, you aren't self-employed.  Hopefully you have a rough idea of your annual income.   The first $9275 over your deductions will pay 10%.  After that, up to $37,650 you pay 15%.  The 2016 link above has a link (PDF) to the full table if you need more than that.  Note that that is the first $48,000 in income with your $10,350 in deductions. As a new (very!) small business, the IRS has lots of advice and information for you. Start at https://www.irs.gov/businesses/small-businesses-self-employed and be sure you have several pots of coffee or other appropriate aid against somnolence.  By default a single-member LLC is 'disregarded' for tax purposes (at least for Federal, and generally states follow Federal although I don't know Mass. specifically), although it does have other effects. If you go this route you simply include the business income and expenses on Schedule C as part of your individual return on 1040, and the net SE income is included along with your other income (if any) in computing your tax. TurboTax or similar software should handle this for you, although you may need a premium version that costs a little more.  You can 'elect' to have the LLC taxed as a corporation by filing form 8832, see https://www.irs.gov/businesses/small-businesses-self-employed/limited-liability-company-llc . In principle you are supposed to do this when the entity is 'formed', but in practice AIUI if you do it by the end of the year they won't care at all, and if you do it after the end of the year but before or with your first affected return you qualify for automatic 'relief'. However, deciding how to divide the business income/profits into 'reasonable pay' to yourself versus 'dividends' is more complicated, and filling out corporation tax returns in addition to your individual return (which is still required) is more work, in addition to the work and cost of filing and reporting the LLC itself to your state of choice. Unless/until you make something like $50k-100k a year this probably isn't worth it. 1099 Reporting. Stripe qualifies as a 'payment network' and under a recent law payment networks must annually report to IRS (and copy to you) on form 1099-K if your account exceeds certain thresholds; see https://support.stripe.com/questions/will-i-receive-a-1099-k-and-what-do-i-do-with-it  . Note you are still legally required to report and pay tax on your SE income even if you aren't covered by 1099-K (or other) reporting. Self-employment tax. As a self-employed person (if the LLC is disregarded) you have to pay 'SE' tax that is effectively equivalent to the 'FICA' taxes that would be paid by your employer and you as an employee combined. This is 12.4% for Social Security unless/until your total earned income exceeds a cap (for 2017 $127,200, adjusted yearly for inflation), and 2.9% for Medicare with no limit (plus 'Additional Medicare' tax if you exceed a higher threshold and it isn't 'repealed and replaced'). If the LLC elects corporation status it has to pay you reasonable wages for your services, and withhold+pay FICA on those wages like any other employer. Estimated payments. You are required to pay most of your individual income tax, and SE tax if applicable, during the year (generally 90% of your tax or your tax minus $1,000 whichever is less). Most wage-earners don't notice this because it happens automatically through payroll withholding, but as self-employed you are responsible for making sufficient and timely estimated payments, and will owe a penalty if you don't. However, since this is your first year you may have a 'safe harbor'; if you also have income from an employer (reported on W-2, with withholding) and that withholding is sufficent to pay last year's tax, then you are exempt from the 'underpayment' penalty for this year.  If you elect corporation status then the corporation (which is really just you) must always make timely payments of withheld amounts, according to one of several different schedules that may apply depending on the amounts; I believe it also must make estimated payments for its own liability, if any, but I'm not familiar with that part.

First the ""profit distribution"" issue with Bob's S-Corp which is in fact tax evasion and will probably trigger a very nasty audit. Generally, if you're the sole employee of your own S-Corp, and the whole S-Corp income is from your own personal services, as defined by the IRS - there's no profit there. All the net income from such a S-Corp is subject to SE tax, either through payroll or through your K-1. Claiming anything else would be lying and IRS is notorious for going after people doing that. Second - the reclassification issue. The reason employers classify employees as contractors is to avoid payroll taxes (which the IRS gets through Bob's S-Corp, so it doesn't care) and providing benefits (that is Bob's problem, not the IRS). So in the scenario above, the IRS wouldn't care whose employee Bob is since Bob's S-Corp would have to pay all the same payroll taxes. The reclassification is an issue when employees are abused. See examples of Fedex drivers, where they're classified as contractors and are not getting any benefits, spend their own money on the truck and maintenance, etc. The employees are the ones who sued for reclassification, but in this case the IRS would be interested as well since a huge chunk of payroll taxes was not paid (driver's net is after car maintenance and payments, not before as it would be if he was salaried). So in your scenario reclassification is not as much a concern to Bob as his tax evasion scheme claiming earnings from performing personal services as ""profits from S-Corp"". A precedent to look at, as I mentioned elsewhere, would be the Watson v Commissioner case." "Disclaimer: My answer is based on US tax law, but I assume Australian situation would be similar. The IRS would not be likely to believe your statement that ""I wouldn't have gone to the country if it wasn't for the conference.""  A two-week vacation, with a two-day conference in there, certainly looks like you threw in the conference in order to deduct vacation expenses.  At the very least, you would need a good reason why this conference is necessary to your business. If you can give that reason, it would then depend on the specifics of Australian law.  The vacation is clearly not just incidental to the trip. The registration for the conference is always claimable as a business expense." Not as you suggest. Since you are sole prop, you are taxed on a cash basis. Within reason, you can prepay vendors - so temp to hire through an agency might appear more attractive than direct hire. But there needs to be a justification other than avoidance of taxes. So pre-paying 100k on 12/25 would look fishy as fuck. Plus your quality of candidate will suffer if you need anything other than low skill labor.  Look at your other fully deductible expenses - anything you can prepay-prepay. For example, I set my liability insurance renewal January 15 to provide optionality. But it just shifts one year into another .. Means fuckall if you are in the same marginal bracket next year.  The IRS has also relaxed depreciation on office technology. Computers are now fully deductible rather than being capitalized.  @ 500k revenue you should have a CPA and legal counsel. Simply incorporating isn't tax magic. The purpose is to limit yourersonal liability, not a tax shelter - but shitty things happen once you have employees, don't create the potential for a disgruntled employee lawsuit put your shelter at risk of court judgment.  That said, assuming you aren't dumping a hypothetical on the Internet, congrats - for all the headaches, having employees is the ultimate leverage .. it's like a xerox machine for your labor (including loss of fidelity with each copy) .. Source Sole trader   If you start working for yourself, you’re classed as a self-employed sole trader - even if you’ve not yet told HM Revenue and Customs (HMRC). As a sole trader, you run your own business as an individual. You can keep all your business’s profits after you’ve paid tax on them. You can employ staff. ‘Sole trader’ means you’re responsible for the business, not that you have to work alone.You’re personally responsible for any losses your business makes. Tax responsibilities   You must: You’re personally responsible for any losses your business makes. This is one condition which you would need to have a look. If you do some shoddy work and your client wants to recover the losses they can come after your personal money or property. LLPs have the same probelm too. And you pay NI and income tax on all of your profits.  If you have a partner then both can take out the profits of a limited company, if both are directors. The tax hit will be less as compared to a single person.
