The 2025 tax season begins January 1st, 2026 and the deadline for initial tax return filing, paying taxes due, and if needed, filing extensions is April 15th, 2026 for all states. The deadline for filing tax returns on extension is October 15th, 2026. See the calendars on our Home page for our specific timing deadlines.

It depends. If you have a complex tax situation or your situation has become complex over the previous year, a meeting to discuss the details will be beneficial. If you have filed with us previously and don’t have questions or new changes, it is probably not necessary to schedule a meeting. Many questions can be addressed by emailing Doug or your accountant.

Yes, we would like you to return a signed copy of the engagement letter which you should receive digitally or in the mail at the beginning of tax season. You can return it to us via email, uploading to SmartVault, or mailing it.

Yes! It is very common to not receive all your documents (especially K-1s and investment reports) before it is time to begin submitting them to us. We can begin working once we receive a majority of your documents as long as you provide the rest when you receive it.

We use SmartVault, a secure file management software to receive, store, and send files. You should have received an invitation to create an account when you started working with our firm. Access the login page here. If you never made an account, call our office and we will set you up.

Once you’re logged in, click on View Files and Folders on the lefthand sidebar to upload, then click the link with your name, then the TY23 folder, then Client Source Documents. The blue Upload File button is on the top right of the screen. Check our tutorial here for a detailed guide with pictures.

SmartVault has several helpful tutorials for users. Click the links below.

Email info@dougjmursteincpa.com and provide the email you would like to add to your portal. We will send an invitation to that address to set up an account.

We receive automatic notifications when clients add documents to their SmartVault portal, so we should be alerted and add you to the queue from there. However, uploads to previous tax year folders are not always visible to our accountants. If you are worried that you may have uploaded to the wrong folder or just want to double check, feel free to email info@dougjmursteincpa.com and we will confirm your uploads on our end.

Our accountants prepare returns based on when clients initially submit their documents, so it may take them some time to reach your return in their queue. Keep an eye on your email inbox for a message from them regarding open items (additional information or documentation they need from you to complete preparation). You should also upload any amended or additional documents you might receive later on.

It depends on several factors. Our accountants prepare returns based on when clients initially submit their documents, so it may take them some time to reach your return in their queue. The earlier you submit all your documents, the faster your return should be completed (provided there are no major delays in the process). Delays in answering your accountant’s questions and addressing open items can cause delays in preparation. Please see the calendars on our Home page for this year’s specific dates. We will consider requests to expedite a return, but it is ultimately up to your accountant’s discretion.

• If you have questions about which documents to submit; your open items; changes to information you have already submitted; or estimated payments, email your assigned accountant. You will receive an email from your accountant with open items once they begin preparing your return. If you are not sure who your accountant is you can call our office.

• If you have a question about SmartVault; paying your invoice; making an appointment; or paper copies, email info@dougjmursteincpa.com. You can also use this email if you are not sure who your assigned accountant is.

• If you have a question about notices from the IRS; tax planning; edits to you return; amendments; or are a prospective client, email doug@dougjmursteincpa.com

Call our office (617.505.4121) when you get to our building and we will be happy to come downstairs to meet you.

This year we need to receive the majority documents by February 21st if you want to file by the April deadline (see the calendars on the Home page for dates). If we do not receive your documents by this date we cannot guarantee that your return will be filed before the April deadline and we will likely file your return later on extension. The deadline to submit documents for analysis for tax returns that will be put on extension is March 26th this year.

Form 8879 provides your authorization for our firm to electronically file (eFile) your return. Some states require a separate authorization form to file their residents’ state returns (Massachusetts is one of these and requires Form 8453). Without your signature(s) we cannot eFile your return for you.

Yes— Email info@dougjmursteincpa.com and we will provide a copy of the filing status history from our tax software after you receive your completed returns.

Your invoice is uploaded to the Client Final Tax Returns folder in your SmartVault portal. When your tax return is completed, you will receive an email with a direct link to this folder. If you request a paper copy of your return, your invoice will also be included in this folder.

We can accept payment via

• The online payment page

• A check made out to Doug J. Murstein CPA & Associates

• A completed credit card information form which you can upload to your SmartVault portal

• A call to the office to give your credit card information over the phone. Our number is 617.505.4121 and we are usually in the office from 9-5 on weekdays

Providing financial information for the purpose of filing your tax return does not grant us permission to perform any transactions with that information. We also don’t have the ability to make direct withdrawals from bank accounts even if provided information. Sending a check or submitting credit card details gives us permission and the ability to charge your account while verifying that you approve your invoice.

Individual income tax returns are due on April 15th or the first business day after if the 15th lands on a weekend or holiday. However, the IRS allows taxpayers an automatic six-month extension to file your taxes every year, as long as you complete Form 4868. It is important to note that if you obtain an extension to file, you must still pay your income tax in full by the April deadline. This is because the extension is an extension to file and not an extension to pay. The extension is guaranteed for everyone and there is no penalty or additional fee for requesting one. Common reasons for requesting an extension include a lack of organization, missing information, unanticipated events, or tax planning issues.

See the IRS website for guidance on paying your federal taxes.

State depts of revenue each have their own websites. Massachusetts residents can use MassTaxConnect. If you live in another state, Googling [your state here] + department of revenue should bring you to the appropriate site. If you’re having trouble finding your state’s website, email info@dougjmursteincpa.com and we will help you locate your payment options.

While we can set up an automatic withdrawal from the bank account you provide us, that is typically the extent of our interaction with the IRS regarding your payments. The IRS/state depts of revenue do not notify taxpayers when their payments are processed. However, your IRS account that is linked to your SSN will show you a history of your payments. Learn more about setting up and IRS account. Your bank statement will also show the withdrawal.

State depts of revenue each have their own websites. Massachusetts residents can use MassTaxConnect. If you pay taxes in another state, see this page to find your equivalent website. If you’re having trouble, email info@dougjmursteincpa.com and we will help you locate your payment options.

Estimated taxes are taxes paid to the IRS on earnings which have not had withholdings on them. For example, a self-employed freelancer should make estimated payments on their earnings to reduce liability when taxes are due (think of it like levying a payroll tax on yourself). The IRS assesses an underpayment of estimated tax payment penalty when the tax liability exceeds 10% of the current year tax. There are safe harbor provisions that can be used to reduce or eliminate this, the primary one being paying in amounts equal to or 110% of the prior year’s actual tax. This means that paying estimates will help you avoid penalties and reduce your liability.

See this page for links to each IRS and state website to pay your estimates online.
