Business Tax Returns Prepared With Accuracy and Care
Business tax preparation covers the federal and state returns filed by an entity rather than an individual. ATDS prepares returns for S-Corporations, C-Corporations, partnerships, nonprofits, and estates and trusts. We organize your financial information, prepare the correct return for your entity type, and review it with you in plain language before anything is filed.

Who Business Tax Preparation Is For
ATDS serves a wide range of clients. Here are some of the people this service is built for.
Common Needs We Address
Every situation is different. Here are some of the needs ATDS regularly helps clients resolve.
Filing the correct return for your entity type
Each entity files a different return. We confirm which form applies to your business and prepare it correctly so nothing is filed on the wrong form.
Coordinating business and owner returns
Business income often flows through to an owner's individual return. We prepare both so they line up and nothing is reported twice or missed.
Staying current on filing deadlines
Business deadlines differ from individual deadlines and vary by entity type. We track the dates that apply to you so returns are filed on time.
Prior-year and late business returns
If your business is behind on filing, ATDS prepares prior-year business returns to help you get current.
Business Return Types ATDS Prepares
Different entities file different returns. This comparison shows the return types ATDS prepares so you can see which one applies to your organization.
| Entity Type | Return | Who It Is For | What to Know |
|---|---|---|---|
| S-Corporation | Form 1120-S | Small to mid-size businesses that elected S-Corp status | Income and losses pass through to shareholders, who report them on their individual returns. The S-Corp itself generally does not pay federal income tax. |
| C-Corporation | Form 1120 | Corporations taxed as separate entities | The corporation pays tax on its own income at the corporate level, and shareholders may also be taxed on dividends they receive. |
| Partnership | Form 1065 | General and limited partnerships, and multi-member LLCs taxed as partnerships | The partnership files an information return and issues Schedule K-1s to partners, who report their share on their own returns. |
| Nonprofit | Form 990 | Tax-exempt organizations and 501(c)(3) charities | Nonprofits file an annual information return. The specific Form 990 version depends on the organization's size and gross receipts. |
| Estate and Trust | Form 1041 | Executors, trustees, and fiduciaries managing an estate or trust | Estates and trusts report income, deductions, and distributions, and beneficiaries may receive a Schedule K-1 for their share. |
