Business tax preparation
Business tax preparation that works the way it should — accurate, on time, and coordinated with your full financial picture.
Filing your business return correctly is not optional — and it is not enough on its own. SG Inc CPA handles business tax preparation for medical practice owners, multi-entity operators, and high-income business owners who need returns that are accurate, complete, and connected to the rest of their financial plan — not just submitted by the deadline.
Serving business owners and practice owners in DFW, Texas and the Bay Area, California. Remote clients welcome.
- BUSINESS TAX PREPARATION INCLUDES
What business tax preparation includes
Business tax preparation at SG Inc CPA covers the full scope of what your entity requires — and is reviewed against your tax plan before anything is filed. These are not isolated transactions. They are coordinated filings that feed into your broader financial picture.
01
Federal and state business returns
Accurate preparation and filing of all required federal returns, plus state returns in Texas, California, and any other states where your business has a filing obligation.
02
K-1 preparation for owners
For pass-through entities — S-corps, partnerships, and multi-member LLCs — we prepare Schedule K-1s for all owners so personal returns can be filed accurately and completely.
03
Estimated tax coordination
We calculate and communicate quarterly estimated payment obligations for the business and for owners, so you are not underpaying and facing penalties or overpaying without reason.
04
Multi-state filing
If your business operates across state lines — common for clients with both DFW and Bay Area presence — we handle filing obligations in each relevant state and manage the coordination between them.
05
Extension management
We file extensions where appropriate and track deadlines across all entities, so nothing slips. Extensions are a planning tool, not a sign of disorganisation.
06
Coordination with personal returns
Business returns do not exist in isolation. We ensure what flows through to your personal return — income, deductions, credits, K-1 items — is handled consistently and completely across both filings.
07
Amended returns
If prior-year returns need correction — due to new information, a missed deduction, or a changed entity classification — we handle amended filings accurately and with full documentation.
08
Year-end close support
We work with you in the final weeks of the tax year to ensure books are closed cleanly, year-end adjustments are recorded, and the return can be prepared without a scramble.
- ENTITY TYPES WE FILE FOR
Entity types we file for
We prepare returns across all common business entity structures. If you have more than one entity, we handle them as a coordinated set — not separately invoiced filings that happen to share a client name.
Form 1120-S
S-Corporation
The most common structure for medical practice owners and high-income business owners. Pass-through taxation with salary/distribution planning implications.
Form 1120
C-Corporation
Separate corporate taxpayer. Relevant for certain holding structures, professional service corporations, and clients where double-taxation considerations are outweighed by other benefits.
Form 1065
Partnership / LLC
Multi-member LLCs and partnerships taxed as partnerships. K-1 preparation for all partners. Common in real estate joint ventures and professional group practices.
Schedule C or Form 1120-S
Single-Member LLC
Default disregarded entity treatment or S-corp election. The right filing approach depends on your compensation structure and whether an S-corp election makes sense for your income level.
Multiple returns, one plan
Multi-Entity
Clients with more than one entity — practice plus holding company, operating entity plus real estate LLC — need returns that are coordinated, not filed in isolation.
- The Coordination Difference
The coordination difference
Filing a return accurately is the baseline. What separates SG Inc CPA’s preparation work from a compliance-only service is the layer of review and coordination that happens before the return is submitted. The table below shows what that looks like in practice.
Compliance-only tax filing
- Return filed accurately — that is the whole job
- K-1s produced and sent to owners
- Estimated payments calculated at year-end
- No visibility into prior-year decisions and their impact
- State filings handled as separate obligations
- Filing complete — no further contact until next year
SG Inc CPA business tax preparation
- Return filed accurately and reviewed against your tax plan
- K-1s reviewed for consistency with owner compensation structure and QBI eligibility
- Estimated payments projected and communicated quarterly, adjusted when income shifts
- Prior-year elections and carry-forwards reviewed to inform the current return
- Multi-state filing treated as one coordinated picture, not separate invoices
- Return reviewed with you before filing; questions answered; next-year implications flagged
- Both layers are necessary
Accounting without bookkeeping is impossible — you cannot produce accurate financial statements from disorganised records. Bookkeeping without accounting is incomplete — you have clean data but no financial picture. SG Inc CPA can provide both, or work alongside your existing bookkeeper to handle the accounting layer.
Who this is for
Our business tax preparation clients are typically dealing with financial complexity that makes accuracy and coordination more important than speed or price. These are the situations where we add the most value.
Medical practice owners
S-corps, PLLCs, and professional corporations running clinical operations. Often have multiple entities, K-1 income flowing to personal returns, and significant equipment or facility spend that must be handled correctly across both the business and personal return.
Multi-entity operators
Business owners with more than one entity — operating company, holding company, real estate LLC — where returns need to be filed as a coordinated set rather than independent documents. Mis-coordination between entities is one of the most common sources of errors and missed deductions.
High-income S-corp owners
Business owners who have elected S-corp status and need their salary/distribution split, QBI deduction, and K-1 income handled correctly — and reviewed each year against their compensation structure to ensure the filing reflects their actual plan.
Real estate investors and partnerships
LLCs and partnerships holding investment properties, where Form 1065 and K-1 preparation must account for depreciation, rental income, passive activity rules, and the interaction between investment returns and personal income.
When preparation alone is not enough!
Our business tax preparation clients are typically dealing with financial complexity that makes accuracy and coordination more important than speed or price. These are the situations where we add the most value.
How to get
Started
Organise and gather
We collect your financial records, prior-year returns, and supporting documents. If your books need a year-end close, we coordinate that first so the return can be prepared cleanly.
Review and plan check
Before preparing the return, we review it against your tax plan — checking that prior-year elections, carry-forwards, compensation structure, and deduction opportunities are all reflected correctly.
Prepare and review
The return is prepared and reviewed with you before filing. You understand what is in it, why it looks the way it does, and what the key numbers mean for your next year.
File and follow through
We file on time, confirm receipt, and flag any implications for the following year. Quarterly estimated payments are updated. The loop closes — and we stay in contact.
What clients say
Not sure what your business tax situation actually looks like?
A confidential review takes 30 minutes. We assess your current returns, entity structure, and planning gaps — and give you a clear picture of whether your situation is being handled correctly and completely.
Frequently asked questions
What business entities do you file returns for?
We prepare returns for S-corporations (Form 1120-S), C-corporations (Form 1120), partnerships and multi-member LLCs (Form 1065), and single-member LLCs. For clients with multiple entities, we coordinate all returns as a set and ensure the numbers flowing between them — especially to personal returns via K-1s — are consistent and complete.
Do you handle both federal and state returns?
Yes. We prepare federal returns and state returns in Texas, California, and any other states where your business has a filing obligation. For clients with both DFW and Bay Area operations, multi-state coordination is part of the standard scope — not an add-on.
What is the difference between business tax preparation and tax planning?
Preparation looks backward — it takes the year that has ended and files an accurate return. Planning looks forward — it identifies strategies and structural decisions that reduce what you owe before the year closes. SG Inc CPA does both, and the two work best together: planning changes what the return will look like, preparation captures it correctly. If you are only getting preparation, see our tax planning page.
My books are not in great shape. Can you still prepare my return?
Yes — though disorganised books slow the process and increase the chance of errors or missed deductions. Where needed, we work with you to close out the year, clean up the records, and prepare the return from a solid foundation. If your books are consistently behind, we will also flag whether ongoing bookkeeping or accounting support makes sense as part of your setup going forward.
Can you file an extension if we need more time?
Yes. Extensions are a routine planning tool, not a signal of a problem. We track deadlines across all your entities, file extensions where appropriate, and make sure you understand the timeline and any payment obligations that apply during the extension period.
We filed with a different CPA last year. Can you still take over?
Yes. We review prior-year returns as part of onboarding to understand your history, check for elections or carry-forwards that should be reflected this year, and identify anything that may have been missed. Prior-year returns are also a useful diagnostic — if something was filed incorrectly or incompletely, we can address it with an amended return.
Do you work with clients who are not in DFW or the Bay Area?
Yes. We have offices in Plano, TX and Milpitas, CA, but business tax preparation and filing does not require in-person meetings. If your entity structure and situation are a good fit, location is not a barrier.
