Tax preparation questions
What documents do I need for my tax appointment?
Start with last year's return, every income form you received, such as W-2s and 1099s, and records of deductible expenses. Business owners should add their profit and loss statement and balance sheet, or bank statements for the year. The checklist on this page covers the essentials.
Can you prepare both my personal and business returns?
Yes, and many owners prefer it. Business income often flows onto your personal return, so one firm preparing both keeps everything consistent. If we also keep your books, your business return starts from reconciled numbers.
I received a letter from the IRS. Can you help?
Yes. Many notices simply ask for information or point out a mismatch. We help you understand the letter, compare it with your return, gather documents and prepare a response before the deadline. Read what to do first after an IRS notice.
Can you file back taxes for years I missed?
Yes. We work out which years are needed, gather the income records for each one and prepare the returns. Getting caught up is usually better sooner than later.
How much does tax preparation cost?
It depends on your situation, so we discuss the fee during your free consultation and agree on it in writing before any work begins.
