2025 Tax Law Changed a Lot — Does Your Return Reflect It?

Recent federal legislation changed real rules that affect individual returns: tip income, overtime pay, the standard deduction, and several credits. Software updates the forms. It doesn't always catch what's changed for you specifically.

Frequently Asked Questions

Why should I use a CPA instead of tax software or a national chain?

Every return at Mercer Flanagan is prepared and reviewed by a licensed CPA who meets with you personally — not a seasonal preparer, a call center, or software left to interpret your situation alone. This matters most once your return includes self-employed income, rental property, investments, or multi-state filings.

I'm behind on filing past tax returns. Can you help?

Yes. We regularly help clients catch up on multiple years of late federal and state returns, and filing several years together is often less expensive per return than filing them one at a time. We also review IRS compliance and penalty exposure as part of the process.

Do you handle rental property and investment income on individual returns?

Yes. Rental income, passive activity loss rules, investment accounts, and K-1s from partnerships or S-Corps are all areas we handle regularly on individual returns, along with sale of property or investments when they occur.

I work in DC or live in one state and work in another. Does that complicate my taxes?

It can, depending on your specific situation, since multi-state and DC commuter filings involve residency rules and reciprocity agreements that vary by jurisdiction. We review this as part of your return to make sure withholding and filings are set up correctly.

Are you available for tax questions outside of tax season?

Yes. We provide year-round access for tax questions, life event planning such as marriage, divorce, or inheritance, and quarterly estimated tax guidance — not just during filing season.
