Question 2

How is self-employment tax calculated?

Accepted Answer

Self-employment tax is 15.3% (12.4% Social Security + 2.9% Medicare) applied to 92.35% of your net earnings. The Social Security portion applies only up to the 2026 wage base of $184,500 (from SSA.gov). An additional 0.9% Medicare tax applies on SE income above $200,000. Half of SE tax is deductible. The worksheet also adds your entered marginal income tax rate to estimate total quarterly payments.

Question 3

What are the 2026 estimated tax due dates?

Accepted Answer

Q1: April 15, 2026. Q2: June 15, 2026. Q3: September 15, 2026. Q4: January 15, 2027. These are the standard IRS Form 1040-ES quarterly payment dates.

Question 4

Can I import bank and credit card CSV files?

Accepted Answer

Yes. The CSV import wizard auto-maps columns from common US bank exports (Chase, Bank of America, Wells Fargo, etc.). It detects duplicates by matching date + amount + description, and applies your auto-categorization rules to assign Schedule C categories automatically.

Accepted Answer

The app uses the IRS simplified method: $5 per square foot of dedicated home office space, up to 300 square feet, for a maximum deduction of $1,500. Enter your office size in Settings and the deduction appears on Schedule C Line 30.
