Frequently Asked Questions
U.S. income tax rates vary depending on the state in which the corporation is incorporated, and generally range from about 8% to 21%. U.S. corporations must file their financial statements by April 15 following the end of their fiscal year (generally January 1 to December 31).
The IRS automatically sends mail to the address recorded on the filed tax return. If a client changes their registered agent or registered-agent address without informing the provider, the return is filed and signed with the old address, and the new agent will never receive the IRS mail. Clients must always notify the provider of any registered-agent or address change before filing.
The IRS does not issue a standalone 'tax payment certificate.' Records can normally be obtained by calling the IRS, or by pulling e-filed records if a director holds a U.S. tax ID (SSN/ITIN). In special cases the client can write to the IRS to request a status/compliance letter; IRS processing typically takes around 3 months.
The standard U.S. LLC accounting/tax-filing product applies to LLCs with two or more members. A single-member LLC is treated as a disregarded entity (like a sole proprietorship) and is not regarded as separate from its owner for U.S. tax purposes, which raises more complex personal income tax, foreign-source income, and withholding tax issues. Single-member LLC tax filing is therefore not currently offered.
Form 1125-E must be filed when the corporation's total receipts are USD 500,000 or more for the tax year.
Before dissolution a U.S. company must complete the full tax return for its final full calendar/fiscal year of operation plus a short-year return covering the period up to the dissolution date. The final full-year return is generally due by April 15 of the following year; missing that deadline may incur additional penalties. Annual report/registration obligations may need to be handled separately.
U.S. federal tax owed to the IRS can be paid electronically through the EFTPS system (Electronic Federal Tax Payment System) at eftps.gov, or by mailing a check to the IRS.
The Texas WebFile RT or XT number is printed on the filing notice that the Texas Comptroller's office mails to the taxpayer. The company's Texas taxpayer number is also required for state filing.
Generally no. When a seller relies entirely on Amazon and the marketplace settings are configured correctly, Amazon automatically collects and remits sales tax as a marketplace facilitator, so a separate sales tax filing service is usually not required. This should always be confirmed against the seller's actual setup.
After Form 8832 is mailed to the IRS, the client should monitor their registered agent for an IRS response and notify the provider as soon as one is received. Separately, for an LLC intended to be taxed as a C-Corp, it must be confirmed before filing whether the LLC was already approved for C-Corp tax treatment in the prior year; if not, the C-Corp election must be filed again, and prior-year filing information is required.
The IRS sends mail and notifications to the address/registered agent recorded on the company's filings. If the client uses their own registered agent rather than the provider's, IRS correspondence goes directly to that agent and the provider will not see it. It is recommended that the client transfer the registered agent to the provider so all government mail passes through the provider and tax issues are caught immediately. Clients keeping their own agent should actively monitor it for IRS correspondence.
