After a motor vehicle accident, the legal paperwork is only one part of the financial story. Many people later realize that accident-related income changes, reimbursements, or settlement timing can affect their tax filing. For readers comparing options, the key question is not just whether a firm handles injury claims—it’s whether you’ll be able to organize tax-relevant records and ask the right IRS-related questions at the right time.
William Mattar Accident Lawyers lists an office/intake location at 500 N Broadway Suite 161-C, Jericho, NY 11753 and can be reached by phone at (516) 444-4444. Public listings also show a 5.0 rating from 75 reviewers. If you’re weighing whether to contact them, here’s a decision guide centered on tax preparation realities (not a generic personal injury overview).
Start with the tax impact you’re actually worried about
Before you contact any injury attorney, write down what tax issue you’re anticipating. Common triggers include changes to wages, reimbursement for losses, or the timing of settlement proceeds. When you call or submit forms, try to describe your situation in tax-related terms: did your income stop, resume, or change? Were you paid for expenses that could be treated differently for tax purposes? Are you trying to understand how an IRS filing might need supporting documentation?
Use the filing deadline as your organizing deadline
If your accident occurred in a prior tax year or near year-end, ask yourself whether you’re preparing returns with incomplete documentation. A firm you choose should help you think in terms of record-keeping, especially around documentation that later supports your tax return, deductible treatment of expenses, or questions you may have about deduction and reporting.
Confirm how the firm helps you connect claim records to tax paperwork
In real life, “tax help” can mean different things. Some firms support you by helping you gather and label claim documents that you’ll need when filing, while others may focus on the injury claim process itself. The practical goal is that your settlement timeline and supporting records are clear enough to give your CPA or tax preparer something coherent.
For William Mattar, the public contact page emphasizes intake and accident claim support, including a call line that says it is open 24/7, with contact at (516) 444-4444 and a form-based intake process. Use that access to ask one targeted question early: what documents do they typically help clients preserve that may matter later for IRS-related filing questions?
Ask how they handle documentation that matters months later
Many tax problems aren’t created on the day of the accident—they’re created later, when records are missing or scattered. When you talk to the intake team, don’t only ask about case strategy. Ask about documentation habits:
- Do they provide a clear record checklist you can keep for your return preparation?
- How do they capture key dates that affect reporting timing?
- What happens if you need a paper trail for income changes, reimbursements, or expense categories?
Your goal is to avoid discovering, during tax filing season, that you can’t explain the “why” behind income or expense changes. If the response is vague, that’s not automatically a deal-breaker—but it is a signal to be more proactive with your own record collection.
Verify fit for your Long Island (Jericho) situation
Because William Mattar lists a Jericho address on its public contact page, it may be a practical option if you’re in the Long Island area and want a local intake point while your claim moves forward. But location should be only one factor. The deeper fit questions are: Are you comfortable discussing tax-related record concerns with intake? Do you have a CPA or tax preparer you can involve, and can the attorney’s office coordinate around documentation needs?
As a final step, look up their official contact page and confirm current intake information, including the phone number and address. Then prepare a short note for your first call that specifically mentions tax, IRS filing timing, and what documents you think you’ll need for your return.

Choosing a personal injury firm is about the whole claim—not just the settlement. If you anticipate tax questions, use your first contact to confirm how they support record clarity and IRS-related filing readiness. That’s the most practical way to reduce surprises when it’s time to file your return.
