03Why choose us

Anyone can file a return.

The difference isn't the software — every office has the same software. It's who reads your file, how fast they get back to you, and whether they're still there when a letter arrives in the fall.

08FAQ

Questions we
hear weekly.

If yours isn't here, just ask. We answer questions before you're a client too.

  • For most individuals: a photo ID, Social Security cards or ITIN letters for everyone on the return, all W-2s and 1099s, mortgage interest (1098) and property tax statements, tuition (1098-T) and student loan interest, child-care provider details, and last year's return if you have it. Businesses should also bring profit-and-loss and balance-sheet reports, payroll records, asset purchases and any 1099s issued. Not sure? Book a free consultation and we'll send you a checklist built for your exact situation — you'll never guess.
