Don't see your question? Write to us and we'll reply within one business day.
01Do you work with individuals or only with businesses?
Both. We prepare personal and family returns, and we handle accounting, payroll and taxes for businesses of all sizes.
02Can I file taxes without a Social Security number?
Yes. If you're not eligible for an SSN, you can file with an ITIN. We help you apply for or renew it with Form W-7 along with your tax return.
03I received a letter from the IRS. What should I do?
Don't ignore it, and respect the deadline it gives. Send us a copy: we review it, explain what it means and prepare the right response or payment plan.
04I have accounts in another country. Do I need to report them?
If you're a U.S. tax resident, you generally must report your worldwide income and, depending on the balances, your foreign accounts (FBAR and Form 8938). We review your case and apply credits to avoid double taxation.
05Do you work remotely?
Yes. You can visit our office or work with us by phone, video call and email, sending your documents securely.
