Missouri Tax Services

Tax Services in Missouri for Individuals & Businesses

Need help preparing your Missouri taxes, filing a business return, catching up on back taxes, or planning for your next tax year? BCHP Tax provides tax preparation and tax support for individuals, families, self-employed taxpayers, and businesses.

What tax services are available in Missouri?

Missouri tax services can include individual and business tax preparation, federal and Missouri income tax returns, 1099 and self-employed tax filing, LLC and S-Corp tax support, prior-year returns, amended returns, tax planning, and help with tax notices or unfiled returns.

Missouri taxpayers can have different filing requirements depending on residency, income sources, business structure, and other circumstances. We help organize those details so your tax return is prepared around your actual situation.

Get Started With Missouri Tax Services

Missouri Tax Services We Provide

Tax preparation is not the same for every taxpayer. A W-2 employee, independent contractor, real estate investor, and business owner can have very different reporting and tax-planning needs.

Individual Tax Preparation

Preparation and review of personal federal and Missouri income tax returns for individuals and families.

Self-Employed & 1099 Taxes

Tax preparation for freelancers, independent contractors, consultants, gig workers, and other self-employed taxpayers.

Small Business Tax Services

Tax support for small-business owners who need help preparing returns, organizing records, and planning for tax obligations.

LLC Tax Services

Support for LLC owners based on how the business is classified and taxed for federal and Missouri purposes.

S-Corp Tax Preparation

Tax preparation and planning support for S-Corporation owners, including business and owner-level tax considerations.

Partnership Tax Services

Support for partnerships and businesses that pass income through to their partners.

Back Taxes & Prior-Year Returns

Help organizing and preparing missing or prior-year tax returns when you need to get your filings back on track.

Tax Planning

Year-round planning to help you understand potential tax consequences before major financial or business decisions.

Why Missouri Tax Preparation Is Different

Missouri has its own income tax rules and filing requirements. Your Missouri return is not simply a copy of your federal return.

Your filing situation can also change depending on whether you are a Missouri resident, part-year resident, or nonresident with Missouri-source income.

Missouri Residents

Missouri residents generally report income according to Missouri’s individual income tax rules and applicable federal information.

Part-Year Residents

If you moved into or out of Missouri during the tax year, your filing situation may require special consideration for the period you were a resident and the income connected to Missouri.

Missouri Nonresidents

Living outside Missouri does not automatically eliminate Missouri tax obligations. Missouri-source income may create a state filing requirement.

Out-of-State Income

Missouri residents who earn income from another state may need to account for that income and applicable credits or adjustments when preparing their Missouri return.

Individual Tax Preparation in Missouri

Individual tax preparation involves more than entering numbers into a tax form. Your filing status, income, deductions, credits, dependents, investments, and other financial circumstances can all affect your return.

We can help with tax situations involving:

  • W-2 employment income
  • 1099 income
  • Self-employment income
  • Multiple sources of income
  • Dependents and family-related tax situations
  • Investment income
  • Retirement income
  • Rental income
  • Prior-year returns
  • Amended returns
  • Missouri and federal tax filing
  • Applicable deductions and credits

Tax Services for Self-Employed & 1099 Workers

Freelancers, contractors, consultants, and gig workers often have more complicated tax situations than employees who receive only W-2 wages.

Your tax preparation may need to account for business income, deductible expenses, estimated payments, and self-employment tax.

Self-employed tax support can include:

  • 1099 income reporting
  • Schedule C income and expenses
  • Business expense organization
  • Estimated tax planning
  • Self-employment tax considerations
  • Home-office expenses where applicable
  • Business-use vehicle expenses where applicable
  • Quarterly tax planning
  • Federal and Missouri tax filing

Small Business Tax Services in Missouri

Business taxes can involve more than preparing an annual return. Your business structure, accounting records, income, expenses, estimated payments, payroll, and state obligations can all matter.

We provide tax support for business owners dealing with:

Sole Proprietorships

Business income and expenses generally flow through to the owner’s individual tax return.

LLCs

LLC tax treatment depends on how the entity is classified for federal tax purposes and the applicable Missouri rules.

S-Corporations

S-Corp owners may need coordinated business and personal tax preparation.

Partnerships

Partnerships generally involve business-level reporting and the allocation of income to partners.

Missouri business tax matters:

Missouri’s Department of Revenue provides different filing requirements for different business structures. For example, a Missouri sole proprietorship generally reports business income through the owner’s individual return, while an LLC taxed as a partnership can involve a Missouri partnership return and partner-level reporting.

Missouri LLC Tax Services

An LLC does not automatically have one single tax treatment. How the LLC is taxed can depend on its federal classification.

Missouri follows federal classification rules for LLCs in important areas. That means business owners should understand how their LLC is classified before assuming which return they need to file.

We can help Missouri business owners understand the tax preparation requirements associated with their LLC structure and coordinate the applicable business and individual filings.

Moved to Missouri or Out of Missouri?

Moving between states can create additional tax questions. Your filing requirements can depend on when you moved, where you lived during the year, where you worked, and where your income was sourced.

Common situations include:

  • Moving into Missouri during the tax year
  • Moving out of Missouri during the tax year
  • Working in Missouri while living in another state
  • Missouri residents earning income in another state
  • Remote workers with multi-state income
  • Business owners operating across state lines
  • People with Missouri-source income who live elsewhere

Multi-state tax situations should be reviewed based on the applicable tax year and the source of the income rather than relying on a general assumption about residency.

Back Taxes and Unfiled Returns in Missouri

If you have missed one or more tax returns, the problem can become more complicated when penalties, interest, notices, or multiple filing years are involved.

We can help you organize the information needed to address prior-year and unfiled returns.

Back-tax situations may involve:

  • One or more unfiled tax returns
  • Prior-year individual returns
  • Prior-year business returns
  • Missing W-2 or 1099 forms
  • Unorganized business records
  • Outstanding tax balances
  • IRS correspondence
  • Missouri Department of Revenue notices

The correct approach depends on your filing history and the specific tax years involved. We recommend reviewing the situation before deciding which returns need to be prepared.

IRS & Missouri Tax Notice Help

A letter from the IRS or Missouri Department of Revenue does not necessarily mean that you owe the amount shown or that the issue cannot be resolved. The correct response depends on the type of notice, tax year, and information requested.

If you receive a tax notice, keep the complete notice and any attachments. Do not ignore correspondence simply because you disagree with the amount.

We can help you understand the tax information involved and determine what documentation or professional assistance may be appropriate.

Missouri Tax Planning

Tax planning should not begin only after the year has ended. Planning throughout the year can help you understand potential tax consequences before making major financial decisions.

Tax planning may be useful when you:

  • Start a new business
  • Change your business structure
  • Become self-employed
  • Receive significant 1099 income
  • Buy or sell property
  • Receive investment income
  • Retire
  • Move between states
  • Expect a significant change in income
  • Want to better understand estimated tax payments

What Documents Do You Need for Missouri Tax Preparation?

The documents required depend on your income and tax situation. Preparing your records before your appointment can make the process faster and help reduce missing information.

Tax situation Documents that may be needed
W-2 employee W-2 forms, prior-year return, dependent information, and records supporting applicable deductions or credits.
Self-employed 1099 forms, business income records, expense records, mileage or vehicle records where applicable, and prior returns.
Business owner Business income and expense records, entity information, prior business returns, payroll records, and applicable tax documents.
Investor Brokerage statements, investment income information, capital gain or loss records, and related tax forms.

Back taxes Prior tax returns, available income documents, IRS or Missouri notices, and records for the affected tax years.
