Exercise 1: Input the IRS Schedules C from the 2013–2015 income tax returns into a spreadsheet. Add percent columns to the right of the dollar columns for each year. Calculate common-sized percentages by dividing each number for that year by gross receipts for that year. Review the dollars horizontally across the three years and vertically down each year to identify any material irregularities. Review the percentages horizontally across the three years and vertically down each year to identify material irregularities. Determine if there are any material trends or significant single-year changes, such as large increases or decreases.
Input additional metrics from the individual tax returns, including income from wages and salaries, interest earned, and estimated tax payments. Review the dollars horizontally across the three years and vertically down each year to identify any irregularities. Compare estimated tax payments with total taxes owed for each year. Identify any material trends or one-time changes in these data points.
Because inventory was destroyed in a fire and not observed, estimate the ending inventory for 2013 and 2014 using the ratio of cost of goods sold to gross receipts (Method #1). To estimate the 2015 ending inventory, calculate the average of the 2013 and 2014 cost of goods sold and gross receipts and then divide the average cost of goods sold by the average gross receipts to find the ratio. Multiply this ratio by the 2015 gross receipts to estimate the 2015 cost of goods sold.
Assess how the estimated ending inventory affects the individual income tax return figures, including inventory valuation, cost of goods sold, gross profit, and net profit. Add an additional 2015 column with the estimated inventory and recalculate cost of goods sold, gross profit, and net profit accordingly. Compare the estimated ending inventory with what was reported to Sharptop Bank and Southern Appalachian Insurance to determine if there is a material discrepancy.
For extra credit (optional), estimate the 2015 ending inventory by rolling forward the physical inventory from October 31, 2015 (Method #2). Starting with the physical inventory at that date, add purchases made from November 1 through December 31, 2015, according to purchase records, to determine the inventory available for sale. Reduce this total by sales recorded in the November and December Georgia Sales and Use Tax Returns. Adjust sales to wholesale cost. Then, compare this method's estimated inventory with IRS reports.
Optionally, consult industry publications such as the RMA Annual Financial Statement Studies to compare
ratios of cost of goods sold to total revenues for convenience stores, and analyze how these ratios compare to those on the Schedule C for 2015.
This analysis will help identify irregularities, consistency over the years, and evaluate the impact of estimated inventory adjustments on the taxpayer’s reported income, ultimately supporting accurate financial assessment and potential audit considerations.

The task of assessing Schedule C data spanning three consecutive years requires a meticulous approach to data entry, analysis, and interpretation. This process not only involves inputting raw financial data into a structured spreadsheet but also entails rigorous comparative and percentage analyses to uncover irregularities or anomalies. The initial step involves entering the Schedule C data for the years 2013, 2014, and 2015, focusing on key financial metrics, including gross receipts, cost of goods sold, wages, interest earned, and tax payments. These figures form the foundational dataset for subsequent analysis.
Upon data entry, the construction of percentage columns relative to gross receipts allows for a common-sized analysis, standardizing the financial ratios across the three years. This step facilitates easier comparison and trend detection, as percentages normalize dollar amounts and highlight proportional changes over time. By examining these percentages horizontally (across years) and vertically (within each year’s categories), analysts can detect material irregularities, such as disproportionate increases or decreases that warrant further scrutiny.
A critical aspect of the review involves identifying significant trends or exceptional changes in the data. For example, a sudden spike in expenses or a sharp decline in gross profit may indicate underlying issues such as misclassification, unreported income, or financial distress. Comparing estimated tax payments to total tax liabilities establishes the accuracy of payments and helps locate discrepancies that might suggest non-compliance or reporting errors.
Since inventory was destroyed in a fire and not directly observed, an estimation process is essential. The primary method involves calculating the ratio of cost of goods sold to gross receipts for 2013 and 2014 and averaging these ratios to estimate the 2015 inventory. This approach assumes consistency in the business operations across these years. The ratio is multiplied by the 2015 gross receipts to determine an estimated cost of goods sold for 2015, which influences gross profit and net income calculations significantly.

Recalculating the 2015 figures with the estimated inventory offers insights into how inventory valuation impacts taxable income and reported profits. This adjustment allows a comparison between the initially reported figures and those derived from the estimated inventory, highlighting any significant differences. If the estimated ending inventory diverges materially from what was reported to lenders or insurers, this warrants further investigation into the accuracy of reported financials and potential misstatements.
For additional insight, the optional method involves rolling forward physical inventory from October 31, 2015, adding purchases against the remaining inventory, and deducting sales to refine the estimate. This method provides a more dynamic approach, aligning inventory levels closer to operational realities. Combining this with industry ratio comparisons, such as those from the RMA publications, offers benchmarking context, illuminating whether the business’s ratios are typical or deviate significantly from industry standards.
Overall, this comprehensive analysis aids in identifying systemic irregularities, understanding fluctuations, and assessing the reliability of reported financial data. It provides a basis for auditors and financial analysts to evaluate the financial health of the business, ensures compliance with tax reporting requirements, and supports accurate valuation and decision-making processes.
