Professional US Tax Return Filing With Secure Online Process

The main federal tax deadline is April 15 each year. If you need more time, you can request an extension, which gives you until October 15 to file.
Non-resident aliens filing Form 1040-NR may have different deadlines depending on whether they received wages from a U.S. employer, but most must also file by April 15.
Remember: an extension gives more time to file, not more time to pay any tax you owe.

Federal tax is the tax you pay to the U.S. federal government (IRS). It includes tax on your income, self-employment income, investment earnings, and more. This applies to both residents and non-residents who earn U.S. income.

State tax is the tax you pay to the state where you live or earn income. Not all states charge income tax, but many do (like California, New York, and Illinois).

Federal tax goes to the U.S. government, while state tax goes to your state’s government - and both may require separate filings.

Federal income tax withheld is the amount your employer deducts from your paycheck and sends to the IRS on your behalf. The calculation depends on:

1. Your income – the total wages or salary you earn.

2. Filing status – single, married, or head of household.

3. Number of allowances or dependents – entered on your W-4 form.

4. IRS tax tables – used by employers to determine the correct withholding amount.

You can also use online calculators or let US Global Startup handle it for you. We ensure the correct federal tax is withheld so your return is accurate and you receive the maximum refund.

Yes, you can pay federal taxes with a credit card through IRS-approved payment processors. Keep in mind there may be processing fees and interest if the balance is not paid in full.

Federal income tax brackets are the ranges of income taxed at different rates. The U.S. uses a progressive tax system, which means higher income is taxed at higher rates.

For example, in 2025 (for single filers):

• 10% on income up to $11,000

• 12% on income $11,001–$44,725

• 22% on income $44,726–$95,375

• 24% on income $95,376–$182,100

• 32%, 35%, and 37% on higher income levels

Before filing online, gather all documents showing your income, deductions, and tax-related information, such as:

• W-2 forms (wages from employers)

• 1099 forms (freelance, interest, dividends, or other income)

• Previous year’s tax return

• Receipts for deductible expenses (education, medical, or business expenses)

• Social Security Number or ITIN

• Bank details for direct deposit of refunds

Dispensaries in the U.S. must pay federal taxes like any business, including income tax and payroll tax. However, because cannabis is federally illegal, they cannot deduct all ordinary business expenses under IRS Section 280E, which can increase taxable income.

Despite this, dispensaries still file federal tax returns using Form 1120 or 1120-S (for corporations) or Schedule C (for sole proprietors).

Yes, a federal tax ID is another name for an Employer Identification Number (EIN). It’s issued by the IRS to identify businesses, nonprofits, and certain other entities for tax purposes.

Federal withholding tax is the portion of your paycheck that your employer automatically deducts and sends to the IRS. It helps pay your federal income tax throughout the year instead of in a lump sum at tax time.

The amount withheld depends on your income, filing status, and allowances claimed on your W-4 form.

A federal tax ID (EIN) can be retrieved if you’ve lost it. You can:

1. Check your IRS confirmation letter from when you applied.

2. Look on previous tax returns or IRS notices.

3. Call the IRS Business & Specialty Tax Line at 1-800-829-4933 (for U.S. businesses).

No, state tax does not come before federal tax. It’s recommended to file your federal tax return first, because most state returns use information from your federal return. Filing federal first ensures your state return is accurate and avoids errors.

Generally, federal tax refunds are not taxable because they are simply a return of the money you overpaid in taxes. However, if you claimed certain deductions or credits in a previous year that reduced your taxable income, part of your refund might be taxable.
