Built for owner-operators.
Tax services for small business owners who'd rather run the business than chase receipts. Records go into one secure vault, and your consultant asks the questions so you don't have to remember them.
Planning before the deadline.
Quarterly planning consultations look at profit, owner pay and estimated payments, so what you owe in the spring is a number you've already seen.
Which business return do you file?
The form depends on how your business is taxed, not only what it's called. A single-member LLC, for instance, is usually reported on your own return.
| Business type | Return | Due (calendar year) | Extension |
|---|---|---|---|
| Sole proprietor or single-member LLC | Schedule C with Form 1040 | April 15 | 6 months (Form 4868) |
| Partnership or multi-member LLC | Form 1065 and K-1s | March 15 | 6 months (Form 7004) |
| S corporation | Form 1120-S and K-1s | March 15 | 6 months (Form 7004) |
| C corporation | Form 1120 | April 15 | 6 months (Form 7004) |
Weekends and holidays move a due date to the next business day. Dates are from IRS Publication 509.
Is this the right fit for your business?
A good fit if you: own an LLC, S corporation, partnership or a Schedule C business that's growing; earn income in more than one state; want someone to look at your numbers during the year; or just received an IRS letter.
Not the right fit if you: need full-time bookkeeping or payroll processing from the same firm. We focus on the tax side and will work alongside your bookkeeper. Searching for accounting and tax services for small business often means both, so it's better to ask us before assuming.
LLC vs S-corp: what changes at tax time
An LLC taxed as an S-corp can save self-employment tax on profit taken as distributions, but you have to pay yourself a reasonable salary, run payroll and file a separate return. As a rough rule of thumb, owners start looking at the election once net profit is solidly above what a reasonable salary would be. It varies.
To switch, Form 2553 is generally due within two months and 15 days of the start of the year you want it to apply.
If you searched for premium tax & business services llc, here's the short version of what we'd do first: look at your profit, your owner pay and your state, then tell you whether the election saves money or just adds paperwork.
What to gather for business tax filing
A profit and loss statement and balance sheet, bank and card statements, payroll reports, 1099s you issued and received, K-1s, asset purchases, a mileage log and last year's returns. If your books are messy, send them anyway. A document checklist covers the rest, and your consultant will say what's missing.
What business tax services cost
Business returns are quoted per return because entity type, number of states and the state of your books change the work. Our Business plan includes up to three states, LLC and S-corp filings, quarterly planning, IRS audit support and a dedicated consultant. See pricing for what each plan includes, or ask for a quote.
Business tax services FAQs
What types of business tax returns do you prepare?
Sole proprietor returns (Schedule C), single-member and multi-member LLCs, partnerships, S corporations and C corporations, plus the owner's personal return that sits alongside them. If you have more than one entity, mention it in your first message and we'll quote accordingly. Our multi-state tax filing service covers businesses with income in other states.
Do small businesses need a CPA or tax preparer?
There's no rule that you need a CPA. Anyone with a PTIN can prepare a return for pay, and the IRS suggests asking about credentials first. What matters is whether they've handled your entity type. Once you have partners, payroll or several states, an experienced preparer is cheaper than fixing an error later.
What documents do I need for business tax filing?
Profit and loss, balance sheet, bank statements, payroll reports, 1099s, K-1s, asset purchases and last year's returns. A mileage log helps if you drive for work. Upload everything to your secure folder, not by email. Use the document checklist to track what's in.
What does your business tax package include?
Our Business plan covers LLC and S-corp filings, up to three states, quarterly planning consultations, IRS audit support and a dedicated consultant. It's quoted per return so the price fits the work. If you'd like to see how it compares with the other plans, our pricing page lays them out side by side.
LLC vs S-corp: which is better for taxes?
Neither is better by default. An S-corp can lower self-employment tax once profit is high enough, but it adds payroll, a reasonable salary and a separate return. For many owners, a plain LLC stays simpler and cheaper. We run your numbers both ways before suggesting a change, and our tax planning & consulting service can help you decide.
When are business tax returns due?
For calendar-year businesses, partnerships and S corporations file by March 15, while C corporations and Schedule C filers file by April 15. Extensions give six months to file but not to pay. If a date lands on a weekend or holiday, it moves to the next business day. See the IRS calendar on our home page.
