The income should be reported by the individual or business that provided the service and earned the income. If the 1099 is in your name, you could ask the issuing Company to change to the S-Corp if that is who earned the income. In the future, have a written agreement between your S-Corp and the Company you are providing service. Also, provide them with a Form W9, so they know where to report the 1099 income at year end.

Generally, the transfer of tangible personal property is the trigger for a sales tax event. In this case, it may be necessary to review the various aspects of a typical transaction to determine if any portion thereof would be subject to sales tax. However, generally speaking, receipts from the sale “Marketing”, "Media Placement Services" and "Web Site Networks" are not subject to State or local sales and compensating use taxes provided your organization does not sell or otherwise transfer any tangible personal property to its clients in conjunction with these activities or perform any services otherwise taxable under Section 1105(c) of the Tax Law in conjunction with these activities. (See, Advertising Agencies, Technical Services Bureau Memorandum, June 10, 1983, TSB-M-83(16)S.

First I'm lot a tax attorney or even know anything about Malaysian tax law. I'm however a person that has moved around a lot and have encounter this situation before. You will must likely have to declare your US income in your home country. However some local tax laws allow for a deduction of foreign tax paid at source. I have not found a US tax treaty between US and Malysia but you should contact a local tax attorney or the tax agency there and ask if they allow deductions or exemptions for foreign tax paid at source. If they do, you would declare your income and deduct the amount of tax already paid to the US. You may or may not still be liable for additional tax on that income. Again it depends on local tax rates and policies. It's never a good idea to hide income from your tax agency though.

Doesnt matter for Federal Income Taxes, Only State Income Taxes. You will have to report the income in the State where you generate the income and reside. So report the income in California. But, If you do conduct business in Montana then you would have to complete a Non-Resident Tax Return.

Yes you should be reporting the capital contributions. Under the old Form 5472 rules, it's true that only items that impacted taxable income would be reportable transactions. So, a capital contribution by you to the corporation would not be reportable, unless the equity contribution was somehow below or above a fair value contribution in exchange for services that you might provide for the corporation - essentially an imputed reportable transactions. When the IRS changed the Form 5472 rules to require non-U.S. owned single member LLC's, they expanded the reportable transaction definition to include virtually everything. The term “transaction” is defined in Treas. Regs. Section 1.482-1(i)(7) to include any sale, assignment, lease, license, loan, advance, contribution or other transfer of any interest in or a right to use any property or money, as well as the performance of any services for the benefit of, or on behalf of, another taxpayer. So, for example, contributions and distributions would be considered reportable transactions with respect to such entities. These amounts can be reported on Lines 12 and 25 with an explanatory footnote that clarities the amounts are capital contributions and not amounts that impact taxable income.
