1. The real-time tax forecast

Go to TaxForecast. You'll see a live view of your projected federal + state liability for the current tax year, recalculated every time a transaction is classified, a deduction is added, or income is recognized.

A typical forecast breakdown:

Gross revenue (YTD)$420,000
Deductible expenses-$186,000
Net business income$234,000
Solo 401(k) contribution-$31,000
Health insurance-$14,400
Adjusted gross income$188,600
Federal income tax (est.)$38,742
Self-employment tax$22,044
State tax (FL)$0
Total projected liability$60,786

The forecast updates within seconds of any change. Add a new deduction — watch total liability drop. Categorize a new income source — watch it rise. This is the feedback loop that makes tax planning actually happen throughout the year instead of at filing time.

Entity vs consolidated: Each entity has its own forecast. Consolidated view (Pro+) rolls up multi-entity P&L into a single personal tax forecast for K-1 holders, S-Corp owners, and pass-through partners.

2. The deduction simulator

The simulator lets you model the tax impact of a purchase, expense, or contribution before you make it. Open TaxSimulator, and plug in:

You'll see the incremental tax change immediately — "This purchase lowers your 2026 federal liability by $14,280 and pushes $3,500 of state liability into 2027." Compare up to 4 scenarios side-by-side.

Pro tier required. The deduction simulator is available on Pro, Family Office, Partner, and Enterprise. Free and Starter see the basic forecast without the what-if modeling.

3. §179 & §280F depreciation

HaraPro tracks depreciation automatically for every capitalizable asset — computers, vehicles, office furniture, equipment — with full compliance for §179 expensing, bonus depreciation, and the §280F luxury-auto limits.

Add an asset via AssetsNew asset. Enter:

HaraPro then calculates current-year deduction, future-year schedule, and flags any §280F limits or recapture risk. At tax time, this feeds directly into Schedule C, Form 4562, or Form 2106.

4. Retirement plans

For self-employed owners, the right retirement plan can shelter $30K–$300K+ per year. HaraPro models:

Open RetirementModel plans and HaraPro will show you max contribution limits and projected tax savings for each plan type, based on your income. If you have an existing plan, enter its details and contributions will flow into the forecast automatically.

Heads up: DB and Cash Balance plans require an actuary to set up and administer. HaraPro models the economics but doesn't replace an actuary. We can refer you to qualified TPAs on request.

5. Quarterly estimates

Self-employed and S-Corp owners must pay estimated taxes quarterly (April 15, June 15, September 15, January 15). Under-paying triggers IRS penalties.

Open TaxEstimates. HaraPro shows your projected liability for the year, how much you've already paid (via W-2 withholding, 1099 withholding, and prior quarterly payments), and how much you owe for each remaining quarter.

HaraPro uses both the safe harbor method (100% of prior year, 110% if AGI > $150K) and the annualized income method — and tells you which is cheaper for your situation this quarter.

6. Tax calendar & alerts

The Tax Calendar shows every federal and state deadline relevant to your entity mix:

You get email alerts 14 and 3 days before each deadline. Custom alerts can be added.

7. IRS forms generation

Pro+ tiers can generate filled IRS forms directly from HaraPro. Go to TaxForms. Pick a form and HaraPro pre-fills from your bookkeeping data:

Generated PDFs are saved automatically to File Vault under the entity + tax year, so your filing record is preserved forever with version history.

Important: These forms are intended to give you and your CPA a clear picture of expected filings. They are not filed electronically with the IRS from HaraPro. Your CPA should review and e-file through their authorized software. See the CPA export package →
