You wanted a list of deductions. The list is not where the money is. Almost everything that legitimately lowers a bill gets decided while the year is still open, in how the business is organized and how money moves through it. Here is the honest shape of it, and then twenty minutes to find out which of it applies to you.
The levers are the same handful a planner walks every year: how the business is organized, how the owner takes money out of it, what is put away for retirement and through which vehicle, whether a large purchase or a chunk of income can sit in one year instead of the next, and whether the books are clean enough to defend any of it later. Which of those apply to you is settled by your own return and by the year you are standing in, which is why no article can answer it for you. Twenty minutes, no charge. Steven Palmieri reads last year's return and your current books, names the levers that sat open and went unused, and tells you which ones are still open right now. Elsewhere that plan is sold as a $15,000 project. Here it comes with the work. Fill this in and pick a time.
None of that is exotic and none of it is a loophole. The reason it never happened to you is duller than that, and it is worth being annoyed about.
Your filer met the numbers months after the last decision that could have changed them. The levers had closed on their own by then, quietly, and nobody mentioned it. Nothing was hidden from you. It was simply never anybody's job to look early, and looking early is the whole job of the twenty minutes.
The cheap way to a smaller number is to hire whoever charges least and lets through what should not go through. That holds up until a letter arrives, and the person who typed the return is not the one who has to sit with it. You are. Book the twenty minutes and hear where you actually stand instead.
Any real move has to survive a question asked a year or two later, and the answer to it lives in your bookkeeping. When the books get rebuilt once a year out of a bank feed and a folder of receipts, there is nothing under the position to stand on. You get a straight verdict on that in the same call.
Not honestly. The categories above are most of the map, but which of them applies to you is settled by how the entity is set up, how you are paid, what retirement structure exists, and what the numbers did this year. A generic list is how owners end up claiming something they never qualified for and paying for it later with interest. Twenty minutes with your actual return is the short honest route.
Nobody can promise that before reading the return, and anybody promising it on a landing page is selling you something. Some years there is real room. Some years the earlier choices already used it up, and the honest answer is that the work belongs to the year ahead and starts now. You will hear which one you are in on the call.
That depends on the month and on which lever. Some close at the end of the year, some close the moment payroll is set, and a few can still move after the calendar turns. Working out which doors are still open is most of what you leave the call with, so take the earlier slot rather than the later one.
Steven Palmieri, reading your return himself rather than handing it to a seasonal preparer. The practice does fractional finance leadership, monthly bookkeeping and tax filing, and no audit or attestation work. If a lender ever wants audited statements you will be told plainly that a different kind of firm does that piece. Ask him whatever you like in the twenty minutes.
Last year's business return, the personal one if there is a personal one, and whatever access you have to the current books. Read only access is fine. Keep the paperwork from when the entity was set up nearby if you can lay hands on it. If you can find none of it, pick a time anyway and bring what you remember.
