Tax center
The official IRS and Maryland pages our clients ask for most, in one place — refund status, payments, transcripts, forms and the filing dates that matter.
Federal tools
All links go to irs.gov. Anything asking for your details on another domain is not the IRS.
Where's my refund?
Refund status for the current and two prior years. You need your Social Security number, filing status and the exact refund amount.

Calendar-year filers. Every date below moves to the next business day when it lands on a weekend or a federal holiday.
| Date | What is due | Who |
|---|---|---|
| January 15 | Fourth-quarter estimated tax payment for the prior year | Individuals, owners taking distributions |
| January 31 | W-2s to employees, 1099-NEC to contractors and to the IRS | Any business that paid wages or contractors |
| March 15 | Form 1065 and Form 1120-S returns, or an extension | Partnerships, multi-member LLCs, S-corporations |
| April 15 | Form 1040 and Form 1120 returns, first-quarter estimate, IRA contributions | Individuals, sole proprietors, C-corporations |
| April 15 | Maryland annual report and personal property return | Maryland entities |
| June 15 | Second-quarter estimated tax payment | Individuals, owners |

| October 15 | Extended Form 1040 and Form 1120 returns | Individuals, C-corporations |
An extension is not a payment plan. It moves the filing date and nothing else — interest and the late-payment penalty run from the original due date. If money is the problem, file on time anyway and ask us about an installment agreement: late filing and late payment are two separate penalties.
Dates and rules on this page are general information for calendar-year filers, not advice for your situation, and the IRS occasionally shifts deadlines for disaster areas. Confirm your own dates with us — contact the office.
Questions about deadlines and notices
Q When are business and individual tax returns due?
Partnership and S-corporation returns on March 15, C-corporation and individual returns on April 15, extending six months to September 15 and October 15 respectively — each moving to the next business day when it falls on a weekend or federal holiday.
Q Does an extension give me more time to pay?
No. It moves the filing deadline only. Interest and the late-payment penalty run from the original due date, which is why we estimate and pay with the extension instead of waiting for the finished return.
Q How do I check my refund?
Federal refunds through the IRS Where's My Refund tool, which needs your Social Security number, filing status and the exact refund amount; Maryland refunds through the Comptroller of Maryland site. Both are linked above.
Q I received an IRS notice. What should I do first?
Do not ignore it, and do not pay it before it has been read — notices carry response deadlines and some of them are simply wrong. Send us the letter and the return it refers to; we can respond and, if needed, represent you before the IRS.
