What Our Tax Preparation Covers

  • Individual Income Tax Returns

    Filing as an employee, retiree, or investor brings its own quirks. We prepare accurate personal returns, review every income source, and apply the deductions and credits that fit your situation, so you keep more of what you have honestly earned each year.

  • Business and Corporate Return Filing

    Companies of every structure face different filing rules and shifting deadlines. We prepare accurate returns for partnerships, S corporations, C corporations, and sole proprietors, aligning each filing with current regulations while capturing the legitimate deductions that lower what your operation owes each year.

  • Multi State Tax Filing

    Earning income across state lines creates layered obligations that trip up many honest filers. We sort out residency questions, allocate income correctly, and file each required state return, sparing you the confusion of overlapping rules and duplicated tax charged on the same dollars.

  • Prior Year and Amended Returns

    Missed a filing deadline or spotted an error only after submitting your return? We reconstruct records, prepare overdue returns, and file amendments that correct earlier mistakes, helping you resolve back issues cleanly and get with the tax authorities before penalties grow any larger.

  • Self Employed and Freelancer Filing

    Independent income means tracking expenses, quarterly estimates, and self employment obligations that most regular employees never face. We organize your numbers, claim eligible business write offs, and prepare returns that reflect the true cost of running your operation, reporting everything and for you.

  • Electronic Filing and Refund Tracking

    Paper filing slows everything down and quietly invites avoidable errors. We submit your completed return for faster processing, confirm official acceptance, and help you track any refund, so you know where things stand from initial submission through the final deposit into your account.

Questions about your taxes rarely wait politely for April to arrive. We stay reachable long after filing season ends, answering notices, explaining changes, and guiding your decisions whenever they surface, so you're never left guessing about how a single choice affects your taxes.

Frequently Asked Questions

  • How long should I keep my tax records?

    Generally, hold onto your returns and supporting documents for at least three years. Keep them six years if you significantly underreported income, and indefinitely if you never filed or filed a fraudulent return. We carefully help you organize everything you should retain.

  • What happens if I do not file my taxes on time?

    Filing late or not at all triggers penalties and interest, and there is no time limit on how long the authorities can pursue an unfiled return. We help you file every missing return promptly and get you back into full, good standing quickly.

  • How far back can the IRS audit my return?

    The IRS usually reviews returns from the past three years, though it can reach back six years when income is substantially underreported and indefinitely for unfiled or fraudulent returns. We carefully prepare accurate, well documented filings that stand up to that scrutiny.

  • Can a return be amended after it has already been filed?

    Yes. If you discover a mistake or missing information after filing, an amended return corrects it, adjusting income, deductions, or credits. We reliably prepare the amendment carefully and thoroughly file it promptly, limiting interest and penalties while restoring your record to full compliance.

  • What is the difference between a CPA and a regular tax preparer?

    A CPA is a licensed professional who can represent you before the IRS and carefully handle complex situations, while many preparers cannot. At William Diker, CPA in New York, New York, you gain that full credential, depth, and accountability on every return.

  • Do I still need to file if I earned very little income?

    Possibly not, but filing anyway is often wise. Even with low income, you may qualify for refundable credits or a refund of withheld tax. We carefully review your situation and reliably file when it genuinely benefits you, so nothing valuable goes unclaimed.

  • What paperwork should I gather before my return is prepared?

    Collect income forms like W2s and 1099s, records of deductible expenses, prior year returns, and receipts tied to credits. Once you share them, we carefully review everything closely, confirm accuracy, and reliably capture each deduction and credit that applies to your situation.

  • How do I choose a trustworthy tax preparer?

    Look for proper credentials, a verifiable track record, year round availability, and someone who signs your return. With 45+ years serving New York, New York, William Diker, CPA offers the experience and accountability that separate a dependable professional from a seasonal storefront.
