How we help Nashua individuals and small businesses
NH Tax Advisors is led by Chris Brown, a federally licensed Enrolled Agent. Nashua sits right on the Massachusetts line, and most of our clients here earn a Boston-area or Merrimack Valley paycheck, so the Massachusetts commuter return is the one we prepare most here. We also prepare individual, family, self-employed, and small business returns, and get people caught up when they have fallen behind on filing.

Why Nashua taxpayers choose NH Tax Advisors
If you live in Nashua and work in Massachusetts, there is a good chance you are overpaying and would never know it from your pay stub. Your employer withholds Massachusetts tax on your whole paycheck, including the days you worked from home on this side of the line. Massachusetts is owed nothing for those New Hampshire days, but the tax only comes back if someone apportions your wages to the days you were actually in the state, and that step is easy to skip. So the overpayment just repeats, year after year.
That is the return we do most in Nashua. We apportion your wages to your real day count, file the nonresident return so the money comes back to you, and read the prior year or two to see how long it has been happening and what else got missed. When a question comes up in the fall, you reach the same person who did the return, not a stranger who has never seen your file.

How we work with Nashua individuals and families
Most Nashua households we work with have at least one paycheck coming from across the state line, so we start there and then widen out. We look back at the last year or two you filed to see whether the Massachusetts wages were apportioned or just taxed in full, prepare this year's federal and Massachusetts returns the right way, and set your withholding so you are not handing the state money you will only get back a year later. When the return is ready we walk you through it in plain language, so you know what you are signing and why.
How we work with Nashua businesses
A lot of Nashua's small operators run alongside a regular job: a contractor or landscaper, a stylist or trainer, someone with steady 1099 work on the side. We start with how the money actually comes in, go back through prior returns for expenses that were missed or misclassified, and prepare your Schedule C with the mileage, home office, phone, and equipment sorted out. We set your self-employment tax and quarterly estimates so April does not blindside you, and if you grow to where New Hampshire's Business Profits Tax or Business Enterprise Tax applies, we flag it before the state does.
How we work with Nashua rental property owners
If you rent out property around Nashua or across the river in Hudson, we report the income and expenses on Schedule E and set the depreciation up right, which is the piece most often missed on a rental. We keep repairs apart from improvements, carry the passive losses forward so they are there when you can use them, and take on the setups people ask about, a two-family, a converted apartment, or a place rented by the week. If the property is in another state, we file there too and keep the credit straight so the same income is not taxed twice. And when we take over a return where depreciation was skipped early, correcting it often puts money back in your pocket.
What we handle for Nashua clients
Some people reach us by searching for the best or top tax preparer in Nashua or the nearest accountant; others just want one specific problem off their plate and do not much care about the title. A fair number are sent by a bookkeeper, which makes sense, since keeping the books and filing the return are two different jobs. Here is the work we do, and who each part is for.
Massachusetts commuter returns
The core of Nashua work. Massachusetts taxes the days you actually worked in the state, not your whole salary, so a commuter who works any days from home is usually owed money the employer withheld anyway. We apportion the wages by day count and file the nonresident return so it comes back to you.
Self-employed and 1099 income
A Schedule C built on a genuine look at your costs, mileage and home office included, plus the self-employment tax that surprises everyone in their first year on their own. We set the quarterly estimates so next April is not a scramble.
Small business and LLC taxes
Single-member LLCs and sole proprietors, including Section 179 on equipment, the 1099-NEC filings for people you pay, and a SEP-IRA to shelter part of the profit. We keep an eye on the New Hampshire Business Profits and Enterprise Tax thresholds so they never sneak up on you.
Individual and family tax returns
Your federal return and every state return that rides along with it, prepared and then explained before you sign. Most of our clients come back each year, so the history behind the numbers is already on file with us.
Back taxes and unfiled returns
A single missed year or a run of them, often a Massachusetts year a commuter never realized they owed. We work out what actually has to be filed, file it, and head off the substitute return the IRS will otherwise file for you. Without the lecture.
IRS notices and payment plans
We read what the notice really says, tell you whether it is even correct, and answer it. If the balance is more than you can pay at once, we set up an installment agreement or check whether First Time Abatement can take the penalties off.
Retirement income and Roth conversions
Pensions, Social Security, 401(k) and IRA withdrawals, and required minimum distributions, each with its own rules. We set the withholding so April is calm and map how much to convert to a Roth before it costs you a bracket or a Medicare surcharge.
Investment income and capital gains
Brokerage 1099s with the cost-basis adjustments that trip up the software, capital gains and losses, and the carryforwards that get dropped when a return changes hands. If you sold company stock, we reconcile the basis so you are not taxed twice on it.
Rental property
Schedule E income and expenses, depreciation set up the right way, and repairs kept separate from improvements. Passive losses get tracked so they are waiting when you need them, and a rental where depreciation was missed early is usually worth correcting.
Amended returns
A return already filed that came out wrong, whether you did it or someone else did. We find what was missed, amend it, and chase the refund if one is owed.
What New Hampshire taxes, and what it doesn't
New Hampshire does not tax the wages you earn and has no sales tax, so your Nashua paycheck carries no state return the way it would almost anywhere else. That is exactly why the Massachusetts side matters so much here: Nashua sits a few minutes from the line, and for most working households the only state income tax in the picture is the Massachusetts one, on the days worked across it.
One older detail matters only if you are cleaning up past returns. New Hampshire used to tax interest and dividends on the DP-10, and that tax was repealed starting with 2025. It still applied through 2024, so a back-year filing or an amended 2024 return may carry a little New Hampshire tax on investment income. From 2025 forward, the form is gone.
You don't have to be in Nashua to work with us
The office is a short drive north in Bedford (ZIP 03110), open by appointment whenever you would rather sit down, but most of our Nashua clients never make the trip. Your documents come to us through a secure portal instead of loose email, we go through the finished return with you by phone or video, and you sign electronically. Someone off Main Street in 03060, out by Pheasant Lane, or over in the Broad Street neighborhoods gets the same attention, and the same care with their information, as a client sitting across the desk. We work the same way with clients in Hudson, Hollis, Litchfield, Brookline, Milford, and Pelham, and up toward Merrimack and Manchester.
Frequently asked questions
How do I choose a good tax preparer in Nashua?
Start with the credential. An Enrolled Agent or a CPA can represent you before the IRS; a preparer without one has limited standing the day a notice arrives. In a border city like Nashua, ask whether they actually know the Massachusetts commuter return, because the day-count apportionment is where a commuter overpays or gets money back, and plenty of preparers still hand that part off or file it on paper. Ask whether you can reach them after April, since a lot of questions land in the summer and fall. And be wary of anyone who sets the fee as a share of your refund or promises a bigger refund than the next person before seeing a single document.
I used to commute to Massachusetts but now work from home in Nashua. Did my taxes change?
Yes, and usually in your favor. Massachusetts taxes the income you earn on days you physically work in the state. When you commuted five days a week, most of your wages were Massachusetts-source. Now that you work from home in Nashua, the days at your kitchen table are New Hampshire days, which Massachusetts does not tax. If your employer is still withholding Massachusetts tax on your whole paycheck, you are likely owed money back, and we recover it by apportioning the wages to your real day count on the nonresident return.
My spouse and I both work in Massachusetts. Do we file one nonresident return or two?
You file a joint federal return and then sort out Massachusetts based on how you file there, which is not always the same choice. When both spouses have Massachusetts wages, the day-count apportionment has to be done for each of you separately, since your in-state days are almost never identical. We prepare both apportionments together so neither of you is guessing at your own piece, and so neither one of you overpays because the employer withheld on days worked at home in Nashua.
Should I hire a tax professional, or can I just use tax software?
Software is fine for a straightforward W-2 return with nothing unusual. It starts to cost you once real life shows up: a Massachusetts commuter return, a side business, stock that vested, a rental, a year you did not file. Software will let you enter all of it and will not tell you what you got wrong, and the mistakes on exactly those items are the ones the software cannot see. What you are paying a professional for is someone who catches what the program never flags and who is still there when a letter shows up in September.
I have a year or two I never filed. Where do I start?
You start by not panicking, because this is more common than people think and it is fixable. We pull your IRS records to see what the IRS already has on you, work out which years actually have to be filed, and prepare them so you are back in good standing before the IRS files a substitute return on your behalf, which almost always overstates what you owe. If there is a balance, we set up an installment plan or look at penalty relief. It is done quietly, and nobody is going to make you feel worse about it.

“I had a great experience working with Chris Brown. He was incredibly easy to work with and always very reachable. He would respond within minutes or at most a few hours whenever I had a question.”
