Should I have to pay income tax on contribution to home office rent from company?
This is essentially a reimbursement of your expense. Since you can deduct the expense, the fact that the reimbursement is taxable doesn't affect you much. You deduct your home office expenses on your annual tax return using form 8829. See the IRS site for more details. If you're asking about the UK tax, there may be some other considerations, but from the US tax perspective it is (nearly) a wash.
There is no clear answer, it might be or not be. Depends a lot on your situation. 1)Yes it is taxable but as Italy has a double taxation agreement with UK, you might not have to pay. You can get a detailed guidance on the HMRC website. 2) Apply here for a certificate of residence  3)You can only claim back if Italy taxes you more than UK would. If it is less than you will have to pay the remaining portion to HMRC. You do this in the self assessment form/tax return/call up HMRC. 4)Tell the truth, explain your whole scenario and don't withheld relevant information assuming you may lower you tax by doing so. I'm a Finance major in Finland and here is how it would go here. As you loan money to the company, the company has no income, but gains an asset and a liability. When the company then uses the money to pay the bills it does have expenses that accumulate to the end of the accounting period where they have to be declared. These expenses are payed from the asset gained and has no effect to the liability. When the company then makes a profit it is taxable. How ever this taxable profit may be deducted from from a tax reserve accumulated over the last loss periods up to ten years. When the company then pays the loan back it is divided in principal and interest. The principal payment is a deduction in the company's liabilities and has no tax effect. The interest payment the again does have effect in taxes in the way of decreasing them. On your personal side giving loan has no effect. Getting the principal back has no effect. Getting interest for the loan is taxable income. When there are documents signifying the giving the loan and accounting it over the years, there should be no problem paying it back. It will depend on how much you expect to earn this way, and whether you expect the company to become profitable soon. Has the company just not made a profit yet, or has it actually made a significant loss that your invoices would just be offsetting? If you're earning over £10,000 per year then invoicing through the company is preferable. Above that level, you'd be taking money from the company as dividends after paying 20% corporation tax with no other tax to pay on your personal tax return. As a sole trader you'd be paying 20% income tax and 9% NI. (Note however that the company can only pay dividends from profits, which is a problem if there are significant losses to offset.) Below £10,000, there's little difference. Through the company, you can take a salary of £7956 per year without paying any income tax or NI. With the new £2000 discount on employers' NI you could then take salary up to £10,000 and just pay 12% employee's NI. As a sole trader, you pay 9% Class 4 NI over £7956 and a fixed £143 per year for Class 2 NI. Paying 9% rather than 12% saves you £60, but then you add the £143. In practice the company would work out more expensive at this level because you'll probably want to pay an accountant to deal with the payroll for you. Having the company repay your £2000 from the invoices doesn't really save any tax if the company will become profitable in the future. You don't pay any tax now since the money you receive isn't income, and the company doesn't pay any tax if the extra £2000 of revenue doesn't put it back in profit. However, if the company is profitable next year then it will have an extra £2000 of profit that would otherwise have been offset against this year's loss, and you do end up paying 20% corporation tax on the £2000. You could still have the company repay the loan in order to delay the tax liability, but it's not really tax free money. Loaning additional money to the company has no tax benefit, you just give the company £1000 and get your original £1000 back later. You pay no tax and neither does the company, but it was your money in the first place. Nope pay the employer back the due does not involve any tax. Just keep a record of the transaction so that its available as reference. That may become complicated depending on the State laws. In some States (California for example), LLCs are taxed on gross receipts, so you'll be paying taxes on paying money to yourself. In other States this would be a no-op since the LLC is disregarded. So you need to check your State law. I assume the LLC is not taxed as a corporation since that would be really stupid of course, but if it is then it adds the complexity of the Federal taxes on top as well (corporate entity will pay taxes on your rent, and you'll pay taxes on your dividends to get the money back). The best option would be to take that property out of the LLC (since there's no point in it anyway, if you're the tenant). It actually depends on the services provided. If you're renting through AirBnB, you're likely to provide much more services to the tenants than a traditional rental. It may raise it to a level when it is no longer a passive activity. See here, for starters: Providing substantial services.   If you provide substantial services   that are primarily for your tenant's convenience, such as regular   cleaning, changing linen, or maid service, you report your rental   income and expenses on Schedule C (Form 1040), Profit or Loss From   Business, or Schedule C-EZ (Form 1040), Net Profit From Business. Use   Form 1065, U.S. Return of Partnership Income, if your rental activity   is a partnership (including a partnership with your spouse unless it   is a qualified joint venture). Substantial services do not include the   furnishing of heat and light, cleaning of public areas, trash   collection, etc. For information, see Publication 334, Tax Guide for   Small Business. Also, you may have to pay self-employment tax on your   rental income using Schedule SE (Form 1040), Self-Employment Tax. For   a discussion of “substantial services,” see Real Estate Rents in   Publication 334, chapter 5 "If a country had a genuine completely flat income tax system, then it wouldn't matter who paid the tax since it doesn't depend on the employee's other income. Since not many countries run this, it doesn't really make sense for the employee to ""take the burden"" of the tax, as opposed to merely doing the administration and paying the (probable) amount of tax at payroll, leaving the employee to use their personal tax calculation to correct the payment if necessary. Your prospective employer is probably saying that your tax calculation in Singapore is so simple they can do it for you. They may or may not need to know a lot of information about you in order to do this calculation, depending what the Singapore tax authorities say. If you're not a Singapore national, they may or may not be relying on bilateral tax agreements with your country to assert that you won't have to pay any further tax on the income in your own country. It's possible they're merely asserting that you won't owe anything else in Singapore, and in fact you will have taxes to report (even if it's just reporting to your home tax authority that you've already paid the tax). Still, for a foreign worker a guarantee you won't have to deal with the local tax authority is a good thing to have even if that's all it is. Since there doesn't appear to be any specific allowance for ""tax free money"" in the Singapore tax system, it looks like what you have here is ""just"" the employer agreeing to do something that will normally result in the correct tax being paid in your behalf. This isn't uncommon, but it's also not exactly what you asked for. And in particular if you have two jobs in Singapore then they can't both be doing this, since tax is not flat. The example calculation includes varying tax rates for the first X amount of income that (I assume without checking) are per person, not per employment. Joe's answer has the link. In practice in the UK (for example), there are plenty of UK nationals working in the UK who don't need to do a full tax return and whose tax is collected entirely at source (between PAYE and deductions on bank interest and suchlike). In this sense the employer is required by law to take the responsibility for doing the admin and making the tax payments to HMRC. Note that a UK employer doesn't need to know your circumstances in detail to make the correct payroll deductions: all they need is a so-called ""tax code"", which is calculated by HMRC and communicated to the employer, and which basically encodes how much they can pay you at zero rate before the various tax rate tiers kick in. That's all the employer needs to know here for the typical employee: they don't need to know precisely what credits and liabilities resulted in the figure. However, these employers still don't offer empoyees a net salary (that is, they don't take on the tax burden), because different employees will have different tax codes, which the employer would in effect be cancelling out by offering to pay two people the same net salary regardless of their individual circumstances. The indications seem to be that the same applies in Singapore: this offer is really a net salary subject to certain assumptions (the main one being that you have no other tax liabilities in Singapore). If you're a Singapore millionaire taking that job for fun, you might find that the employer doesn't/can't take on your non-standard tax liability on this marginal income." http://www.irs.gov/publications/p936/ar02.html#en_US_2010_publink1000229891 If you still own it, you get to deduct all of it. In my taxes I did online with TaxAct, it asked if I lived there or not and it just mattered which form it filed for me.  With having tenants it was a 'business' form and I assume it would be a standard schedule A for personal.  Either way the deductions are still mine to take. Source on GOV.UK You may be able to get tax back for some of the bills you have to pay because you have to work at home on a regular basis. You can only claim for things to do with your work, eg business telephone calls or the extra cost of gas and electricity for your work area. You can’t claim for things that you use for both private and business use, eg rent or broadband access. You don’t need to provide records for claims of up to £4 per week (£18 per month). For claims over £4 per week you’ll need to provide evidence of what you’ve spent. Claims up to £2,500   You must claim using a Self Assessment tax return if you already fill one in. If you don’t already fill in a Self Assessment tax return, and your allowable expenses are under £2,500 for the tax year, fill in form P87 and send it to the address on the form. If you’ve made a successful claim in a previous tax year and your expenses are less than £1,000 (or £2,500 for professional fees and subscriptions), you may be able to make your claim by phone. Claims over £2,500   You must claim using a Self Assessment tax return. how much taxes would I pay on my income from the rent they would pay me? The same as on any other income. California doesn't have any special taxes for rental/passive income. Bothe CA and the Federal tax laws do have special treatment, but it is for losses from rental. Income is considered unearned regular income and is taxed at regular brackets. Would I be able to deduct the cost of the mortgage from the rental income? The cost of mortgage, yes. I.e.: the interest you pay. Similarly you can deduct any other expense needed to maintain the property. This is assuming you're renting it out at FMV. If not, would I pay the ordinary income tax on that income? In particular, would I pay CA income tax on it, even though the property would be in WA? Yes. Don't know how WA taxes rental income, but since you are a California tax resident - you will definitely be taxed by California on this, as part of your worldwide income. According to the government website, the answer appears to be no in terms of personal income. However you may want to anyway to start creating RRSP contribution room as well as possibly qualify for GST/HST credit. If your business is registered you are going to be required to file a tax return for it (and if it is a sole proprietorship then you would be required to file a T1 regardless). When all is said and done, it seems that it's probably better to file rather than not file; even if you pay no income tax at least you are sure you won't receive a nasty letter from Revenue Canada in the future :) avoid corporation tax There aren't many avenues to save on corporation tax legally. The best option you can try is paying into a generous pension for yourself, which will save some corporation tax. Buying a house You can claim deduction for the mortgage payments, but profits on selling the house will require paying capital gains tax on the profit. You can rent it out, this will be decided between your mortgage provider and your company, but the rent will go towards as income.  Buying a car Not worth it. You will have to pay Class 1A NI contribution for benefits in kind. Any sane accountant will ask you to buy the car yourself and expense the mileage. Any income generated from the cash you have is taxable. Even the interest being paid on your money is taxable. "After reviewing the tax treaty between New Zealand and Australia, I think the issue is whether or not you have an interest in a ""permanent establishment"" in Australia where you do business.  The bank is not relevant as it is merely the vehicle by which you collect payment and would only come into the picture if you had an income bearing account (which you have indicated you do not). Even if you work out of the offices of the Australian company, you do not have a financial interest in their offices and as such, would pay taxes on the income in New Zealand (see documentation below). https://www.ato.gov.au/business/international-tax-for-business/foreign-residents-doing-business-in-australia/tax-on-income-and-capital-gains/#permanentestablishment" "In the UK it all comes down to what HMRC will allow you to charge without taxing you on the ""rent profit"" and not hitting capital gain tax when you sell the house, it may not all count as your ""main home"" if some is rented out.   (http://www.accountingweb.co.uk/ is a good place to ask this type of questions in the uk)" When evaluating a refinance, it all comes down to the payback. Refinancing costs money in closing costs. There are different reasons for refinancing, and they all have different methods for calculating payback.  One reason to finance is to get a lower interest rate. When determining the payback time, you calculate how long it would take to recover your closing costs with the amount you save in interest. For example, if the closing costs are $2,000, your payback time is 2 years if it takes 2 years to save that amount in interest with the new interest rate vs. the old one. The longer you hold the mortgage after you refinance, the more money you save in interest with the new rate. Generally, it doesn't pay to refinance to a lower rate right before you sell, because you aren't holding the mortgage long enough to see the interest savings. You seem to be 3 years away from selling, so you might be able to see some savings here in the next three years.  A second reason people refinance is to lower their monthly payment if they are having trouble paying it. I see you are considering switching from a 15 year to a 30 year; is one of your goals to reduce your monthly payment? By refinancing to a 30 year, you'll be paying a lot of interest in your first few years of payments, extending the payback time of your lower interest rate.  A third reason people refinance is to pull cash out of their equity. This applies to you as well. Since you are planning on using it to remodel the home you are trying to sell, you have to ask yourself if the renovations you are planning will payoff in the increased sale price of your home. Often, renovations don't increase the value of their home as much as they cost. You do renovations because you will enjoy living in the renovated home, and you get some of your money back when you sell. But sometimes you can increase the value of your home by enough to cover the cost of the renovation. Talk to a real estate agent in your area to get their advice on how much the renovations you are talking about will increase the value of your home.
