Tax Preparation & Filing

Business Tax Preparation

Partnership, S corporation and C corporation tax returns prepared accurately and on time, with K-1s delivered to owners.

Overview

How BATS handles business tax preparation

Business returns carry deadlines that arrive before the personal ones and penalties that add up per owner, per month. We prepare returns for LLCs, partnerships, S corporations and C corporations, reconcile them to your books and deliver K-1s early enough for owners to file their own returns on time.

We work with clients in all 50 states and Washington, D.C., so state-specific rules are covered whether you are in one state or several.

  • S corporations filing Form 1120-S

The process

How it works, step by step

  1. Books review

    We review your year-end trial balance and flag anything that needs correcting before the return.

  2. Adjustments

    We record tax adjustments for depreciation, meals, owner compensation and other book-tax differences.

  3. Owner review

    Owners see the draft return and their K-1 figures before filing.

  4. File and distribute

    We e-file the return and send K-1s to every owner.

Questions

Business Tax Preparation FAQs

11 answers to the questions clients ask us most. Don't see yours? Ask us directly.

Ask a question

When are business returns due?

Partnership and S corporation returns are generally due March 15 for calendar-year businesses, and C corporation returns April 15. Extensions are available, and we file them when books are not ready.

My books are a mess. Can you still help?

Yes. We often clean up the books first (see our QuickBooks cleanup service) and then prepare the return from corrected numbers.

Do you handle state franchise taxes?

Yes. Many states charge franchise, gross-receipts or minimum taxes on businesses regardless of profit, and we include those filings.

What is a K-1?

A Schedule K-1 reports each owner's share of income, deductions and credits from a partnership, S corporation, estate or trust. Owners use it to complete their personal returns, which is why we deliver K-1s as early as possible.

What happens if a partnership or S corporation return is late?

The IRS charges a penalty for each partner or shareholder for each month the return is late, up to 12 months, so even a small business can face a large bill. Filing an extension on time avoids it.

Are business meals deductible?

Business meals are generally 50% deductible when they are properly documented. Entertainment, such as event tickets, is generally not deductible.

Does a single-member LLC file its own return?

By default no. A single-member LLC is disregarded for federal tax and reports on the owner's return. A multi-member LLC files Form 1065 unless it elects to be taxed as a corporation.

What is a pass-through entity tax election?

Many states let partnerships and S corporations pay state income tax at the entity level, which can help owners work around the federal cap on state and local tax deductions. We check whether your state offers it and whether it saves you money.

How much does tax preparation cost?

Fees depend on the forms involved, the number of states and how organised your records are. After a short consultation we give you a written quote before any work starts.

Is my information secure?

Yes. Documents are exchanged through an encrypted client portal, and we follow a written information security plan as the FTC Safeguards Rule requires of tax preparers.

Can you prepare returns for prior years?

Yes. We prepare current and past-year federal and state returns, which is useful if you are catching up or amending.
