Frequently Asked Questions
What qualifications should a tax preparer have?
At minimum, a paid tax preparer must have an IRS-issued PTIN. Look for additional credentials like Enrolled Agent (EA) status, CPA license, or completion of the IRS Annual Filing Season Program. These indicate higher levels of training and accountability.
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.
