Frequently Asked Questions

What qualifications should a tax preparer have?

How much does tax preparation cost?

Simple individual returns (W-2 income only) typically cost $100-$300. Returns with itemized deductions, self-employment income, or rental properties can cost $300-$800 or more. Always ask for a fee estimate upfront before committing.

What documents do I need to bring to my tax preparer?

Bring all W-2s, 1099 forms, records of deductible expenses, last year's tax return, Social Security numbers for all family members, bank account information for direct deposit, and any IRS correspondence you have received.
