ACC-330: Federal Taxation I

A study guide to ACC-330 at SNHU, the course on US individual income tax law, the Internal Revenue Code and preparing federal returns.

Updated October 2026 · 5 min read

ACC-330 at Southern New Hampshire University is Federal Taxation I. SNHU describes it as a course on current US tax laws and the Internal Revenue Code (IRC), along with the source documents associated with federal tax returns for individuals.

Students research and apply the appropriate tax laws to specific circumstances and tax liabilities, prepare federal tax returns, and communicate tax return information to stakeholders.

Tax is a different kind of accounting. Instead of applying broad principles, you apply specific rules with thresholds, limits and exceptions, many of which change from year to year. Success depends on reading the facts carefully, finding the rule that applies and documenting how you reached your answer.

Key Concepts Explained

The Individual Tax Formula

Most individual problems follow one sequence: gross income, minus adjustments, equals adjusted gross income (AGI); minus the standard or itemized deduction (and any qualified business income deduction), equals taxable income; apply the rates; subtract credits; compare with payments.

Example (illustrative figures): Wages $62,000 plus interest $500 give gross income of $62,500. A $2,000 adjustment gives AGI of $60,500. If the applicable deduction were $14,000, taxable income would be $46,500. Tax is then computed from the rate schedule for that year and filing status, and credits reduce it dollar for dollar.

Deductions Versus Credits

A deduction reduces taxable income, so its value depends on the taxpayer's marginal rate. A credit reduces tax directly.

Example: For a taxpayer in a 22% bracket, a $1,000 deduction saves about $220 of tax; a $1,000 credit saves $1,000.

Researching the Code

Tax research means stating the issue, finding the relevant Code section and guidance, applying it to the facts and concluding. Always use the figures for the tax year in your scenario, since many amounts are indexed for inflation.

Working from Source Documents

Because SNHU's description highlights source documents, many tasks give you a set of forms and ask you to prepare the return. Start by sorting the documents: income (W-2, 1099 forms), adjustments, deductions and credits, and payments such as withholding.

Note which line or schedule each figure feeds. Then work through the return in order, checking that totals carry correctly between schedules and the main form.

Keep a short worksheet that explains any judgment calls, such as filing status or whether a dependant qualifies. This makes the return easier to review and gives you material for any client communication the assignment requires.

Client communication tasks reward the same care. Summarize the outcome first (refund or balance due and the main reasons), mention any items the client should keep records for, and avoid quoting Code sections unless the reader needs them. A short, accurate letter is better than a long technical one.

Frequently Asked Questions

What does ACC-330 cover?

SNHU describes it as current US tax law and the Internal Revenue Code for individual federal returns, including research, return preparation and communicating results.

Do I need to memorize tax figures?

Usually you need to know where to find them and how to apply them. Check your instructor's guidance for exams.

What is AGI?

Adjusted gross income: gross income minus specific adjustments. Many limits and phase-outs are based on it.

Is a credit better than a deduction?

A credit of the same amount saves more tax, because it reduces tax directly rather than taxable income.

Can you help with a tax research memo?

Yes. We prepare a model memo for your issue and explain how the authority applies.

Which course follows ACC-330?

SNHU's legacy catalog lists ACC-330 as the prerequisite for ACC-331, Federal Taxation II, which covers business entities.
