Taxes, investments and cash reserves

Current 1.0 tax and banking baseline

Build 3674 is the minimum reliable baseline because Build 3672 corrected the projected tax rate and 3674 repaired employee failures that could distort income.

The official 1.0 release rebalanced taxes with more deductions intended to reward annual growth. It added a ten-percent late fee, partial tax payments, and an EconoView tax area showing current debt and an estimate for the next year. Build 3672 then fixed a projection that could display the wrong tax rate and an IRS contact that appeared too early. Any screenshot or test made before that correction is unsuitable for a current projection table.

The banking overhaul removed negative interest, added daily automatic investment, more detailed investment growth reporting, and partial withdrawals without closing the whole account. Older advice to invest solely to avoid a weekly cash penalty is obsolete. Investments now compete with cash reserves, debt repayment, property, and operating expansion on risk, liquidity, and expected value rather than on avoidance of negative interest.

Hovgaard has not published a complete 1.0 deduction schedule, investment return table, or guaranteed fund performance. Difficulty and custom settings affect tax rates and other economic values. Therefore use the rate, projected liability, fund history, and transaction results shown in the current save. This guide gives formulas and controlled tests, not a promise that a specific purchase erases a fixed percentage of tax or that a fund always earns a quoted return.

Taxable result is not bank cash

Tax planning starts by separating operating profit, accounting deductions, and cash movements.

Sales bring cash and revenue together, but many other events separate them. Buying inventory reduces cash while creating stock; COGS is recognized when resources are sold or consumed. Buying equipment or property consumes cash and may affect deductions under the 1.0 system, but the exact treatment must be observed in EconoView. Borrowing adds cash without being sales revenue. Principal repayment removes cash without being an operating loss.

Use a planning bridge: estimated taxable base equals recognized taxable income minus deductions accepted by the game. Estimated tax equals taxable base times the displayed save-specific rate, subject to the game's own rounding and rules. Cash after tax equals opening cash plus operating cash flows plus financing and investment withdrawals minus purchases, capital spending, investment deposits, debt service, and tax paid. Never infer tax from the change in bank balance alone.

For example, a business earns two hundred thousand of operating profit but buys three hundred thousand of property and receives a two hundred fifty thousand loan. Cash might rise one hundred fifty thousand before other flows even though profit is only two hundred thousand. The tax projection may fall if the property is an eligible deduction, but the loan itself should not be called profit. Record each component and let the corrected EconoView projection reveal the game's treatment.

Read the EconoView tax panel

The projection is a live planning estimate, not an invoice frozen for the year.

Record three items: the tax rate displayed for the save, any amount currently owed, and the estimate for the next tax year. Add the game day and days remaining in the configured year. A growing business can make the estimate rise quickly because recent profitable days are replacing startup losses. A major eligible purchase can move it in the other direction. The number should be monitored after midnight and after material transactions.

Build 3672 fixed a wrong-rate projection. If the panel still appears inconsistent on 3674, first check difficulty, custom settings, date, and whether the figure is current debt or next-year estimate. Then reproduce on an unmodded save. The official F2 channel accepts save data but is one-way; link a Steam discussion if a response is needed.

Do not reserve only the projected amount. Forecast profit through year end, apply the displayed rate conservatively, and compare that forecast with the live estimate. A tax reserve can equal current amount owed plus projected liability through the payment date plus a buffer for faster growth. Update weekly and after opening a large business, changing factory exports, buying property, or closing a loss-making operation.

Build a rolling tax reserve

Treat tax cash as unavailable for expansion even though it remains in the bank.

A simple reserve equals currently owed tax plus projected next-year tax plus a forecast adjustment. The adjustment can be expected remaining taxable profit times the displayed rate, minus profit already reflected in the projection, plus a safety buffer. Because the projection method is not fully published, compare this manual figure with EconoView rather than claiming mathematical identity.

Worked case: EconoView estimates one hundred eighty thousand, the company expects another four hundred thousand of taxable profit, and the displayed rate is fifteen percent. If only half of that future profit appears represented, add thirty thousand for the unreflected half and twenty thousand buffer. Reserve two hundred thirty thousand. This is an illustration; replace every input with the save's values.

Keep the reserve in cash now that negative interest is gone. An investment fund can decline at the payment date, and a property may take time to sell. If cash is temporarily insufficient, 1.0 allows partial tax payments. Paying what is available reduces exposure, but verify in the current interface how the remaining balance and fee are shown. Partial payment is a relief valve, not a reason to underreserve.

Late fees and partial-payment triage

The official ten-percent late fee makes prevention more valuable than speculative return seeking.

When the due date approaches, rank cash uses: preserve the minimum needed to keep profitable operations trading, make the tax payment, meet unavoidable debt service, and defer discretionary expansion. Compare the certain late fee with the uncertain profit from holding inventory, investments, or a new project. A guaranteed ten-percent penalty is usually a severe hurdle, but the game does not publish every timing detail, so inspect the amount due and deadline directly.

If full payment is impossible, use the new partial-payment option and record the remaining balance before and after midnight. Do not assume the fee applies only to the unpaid part or to the original bill without observing the current build. A controlled save test can settle this: save before the deadline, pay a known fraction, advance, record the fee and balance, then reload and compare with no payment.

Avoid asset seizure. An older developer reply confirms that prolonged nonpayment can lead the IRS to take assets, but old grace-period numbers may no longer apply after 1.0. Current guidance should therefore state the consequence without repeating a fixed countdown. Keep vehicles, warehouse shelves, and operating assets out of danger by paying or testing before the deadline rather than relying on Early Access timing.

Deduction testing instead of deduction folklore

Because no complete official deduction table is public, identify eligible spending through controlled before-and-after tests.

Label a save with build, difficulty, game day, displayed tax rate, current projection, and all same-day income. Save immediately before one transaction. Buy one clearly identified asset or expense, advance until the tax panel updates, and record the new projection. Reload and repeat without the purchase. The difference between branches is the observed projection effect under those conditions.

Test categories separately: employee education, equipment, vehicles, interior work, business acquisition, property, factory machinery, inventory, marketing, and investment deposits. Do not combine categories in one day. Repeat on a second day or property before calling the result stable. A current 1.0 community thread reports property as deductible and recommends buying before the tax boundary, but that is a test lead rather than a complete official rule.

Calculate implied tax effect as baseline projection minus purchase-branch projection. Implied deduction estimate equals tax effect divided by the displayed tax rate, if the rate is nonzero. This may be distorted by projection forecasting, timing, rounding, or other income, so publish it as an observation. Never write 'spending one million saves one million in tax'; a deduction, if accepted, reduces a base rather than normally returning the entire purchase price.

Investments after negative interest

The investment decision is now about portfolio purpose, risk, and liquidity rather than avoiding an idle-cash charge.

Assign every dollar to one of four jobs: near-term operating cash, tax and debt reserve, committed expansion, or long-term surplus. Only the last category belongs in a volatile investment fund. Daily auto-investing is useful for consistently sweeping a chosen surplus, but it can starve the next importer order if the amount ignores working-capital cycles.

Partial withdrawal lets the company raise cash without closing the entire position. That improves flexibility but does not eliminate market risk. The value available on the withdrawal day may be below deposits. Investment return equals ending market value plus withdrawals minus deposits divided by a time-weighted or simple capital base; for an everyday game sheet, track net contributions and gain separately rather than claiming a precise annualized return from a short period.

The original developer description said the funds were based on anonymized real-world funds with daily synchronized movement. That statement is historical design context, not a current guarantee that the same mapping or return ranges remain unchanged. Use only the detailed growth values displayed in 1.0. No player action is documented as changing a fund's market path.

Measure investment performance correctly

Account growth is not investment return when daily auto-investing continually adds new principal.

For each day record opening value, deposit, withdrawal, closing value, and net gain. A simple daily gain is closing value minus opening value minus deposits plus withdrawals. Daily return is that gain divided by capital exposed, using opening value plus a timing adjustment when deposits occur during the day. If timing is unclear, report gain dollars and avoid false precision.

Worked week: opening value one hundred thousand, seven daily deposits of five thousand, no withdrawals, closing value one hundred thirty-eight thousand. The account rose thirty-eight thousand, but thirty-five thousand came from contributions. Investment gain is three thousand, not thirty-eight thousand. A naive growth rate of thirty-eight percent is wrong. A rough simple gain on average exposed capital near one hundred seventeen thousand five hundred is about two and a half percent for the observed interval, not a promised annual rate.

Compare funds over the same dates and with the same contribution pattern. Record maximum drawdown as the largest fall from a prior peak. Compare the investment with holding cash, reducing loan principal, or funding a business using stressed expected cash flows. Debt interest avoided is more predictable; business return is controllable but operationally risky; fund return is market-driven. There is no universally best option.

Auto-invest amount and cash-flow guardrails

Automate only the minimum surplus expected after a conservative operating cycle.

Calculate safe daily auto-invest as the lower of average daily free cash flow and stressed daily free cash flow, minus a replenishment margin. Free cash flow here means operating cash after routine orders, payroll, rent, marketing, debt service, and tax accrual. If the stressed figure is negative, disable auto-invest until reserves recover.

Example: normal daily free cash flow is twelve thousand, but the worst comparable week averages five thousand. Upcoming supplier variability requires two thousand per day of extra margin. Safe auto-invest is at most three thousand. Setting twelve thousand would transfer the entire normal surplus and force withdrawals whenever a weak day occurs. Frequent forced withdrawals defeat the purpose and may crystallize a loss.

Audit weekly. Compare auto-invest deposits with actual gain, emergency withdrawals, missed purchases, and minimum cash. Lower the amount when a rival attacks, a factory ramp begins, taxes approach, or a large property offer is outstanding. Raise it only after the operating reserve remains above target for a complete cycle. Automation is a rule, not a substitute for forecasting.

Tax-aware capital allocation

A deduction can improve timing, but it cannot rescue a bad asset or an underfunded operation.

Compare alternatives on after-tax cash and strategic value. For an equipment purchase, include incremental operating contribution, purchase cash, observed projection reduction, resale value, and implementation delay. For property, include rent saved, rental income, occupancy ramp, strategic control, sale liquidity, and observed deduction. For investments, include uncertain gain, drawdown, and liquidity. For debt repayment, include interest avoided and reduced cash flexibility.

Worked comparison: a two-hundred-thousand machine is expected to add twelve thousand contribution per day after ten setup days. A property costs two million, saves two thousand daily rent, earns one thousand rent at stabilized occupancy, and provides site control. An investment has no guaranteed return. A tax effect should be measured but kept separate. Even a large property deduction may not overcome years of low operating yield if the company needs productive capacity now.

Use net present thinking without pretending the game follows real-world tax law. Payback days equal net purchase cash after observed tax effect divided by daily incremental cash benefit. Stress the benefit and include ramp delay. Choose projects that remain solvent before the deduction arrives. Never spend solely to reduce taxes: if a one-dollar purchase reduces tax by only the displayed rate fraction, most of the dollar still leaves the company.

Property purchase near the tax boundary

Timing matters because occupancy and tax effects do not necessarily begin on the same schedule.

A property bought for deduction must still be funded in cash. Before purchase, preserve the tax amount currently owed and enough operating cash for accepted orders. Record the projection immediately before and after the property transaction. Community 1.0 observations report property deductions, but official notes only promise more deductions generally, so the test is essential.

Rental pricing has a seven-day countdown before the new rent applies, according to an April 2026 developer reply. Occupancy then changes over time, with lower rent the primary driver and neighborhood factors also involved. Therefore a property bought just before tax year end may show a projection effect before it reaches stabilized rent. Do not use stabilized rental income to justify near-term tax liquidity.

Create a timeline: offer and purchase date, tax boundary, price-change effective date, expected occupancy observation dates, and earliest prudent sale date. Compare the tax projection branch with a control save. If buying the building would force a late tax balance, the ten-percent fee can overwhelm the benefit. The sequence must preserve solvency first, then optimize deductions.

Tax and investment sensitivity analysis

Stress rates, profit growth, deduction effect, market return, and withdrawal timing together.

Build a matrix with projected operating profit, displayed tax rate, observed deductions, fund return, and cash deadline. Tax estimate equals positive modeled taxable base times rate. Investment ending value equals opening investment plus deposits minus withdrawals plus modeled gain. Closing liquidity subtracts tax and operating commitments. Use zero or negative investment return in the downside rather than a guaranteed positive assumption.

Example: taxable profit one million, observed deduction two hundred thousand, and rate fifteen percent gives modeled tax one hundred twenty thousand. If the deduction proves half as effective, tax becomes one hundred thirty-five thousand. If profit grows twenty percent while deduction stays fixed, tax becomes one hundred fifty thousand. A fund holding the tax reserve that falls ten percent can create an additional shortfall even though the tax model is correct.

Define action thresholds. If projected tax exceeds cash reserve by more than one week's stressed free cash flow, stop auto-invest and discretionary purchases. If a fund drawdown would force late payment, withdraw the tax portion early. If a deduction purchase only works under the most optimistic tax effect and asset return, reject it. Re-run after each major business launch and property acquisition.

Audit sheet and reproducible 1.0 tests

A combined ledger provides evidence for deductions, returns, partial payments, and liquidity decisions.

The daily sheet needs day, build, difficulty, opening cash, operating profit, inventory cash purchases, capital purchases by category, debt flows, tax projection, current tax owed, tax payments, investment opening value, deposits, withdrawals, market gain, closing value, and closing cash. Add notes for patches, rivals, outages, and mods. Use formulas rather than manually overwriting totals.

For deduction tests, branch one save into control and transaction cases. For late-fee tests, branch before the deadline and compare full, partial, and no payment, without risking the main save. For investments, use equal opening value and dates, then compare auto-invest with manual deposits while separating contributions from gains. Version every result as '1.0 Build 3674' and state all custom settings.

At each year end, archive the final projection, actual bill, deductions tested, fee if any, and payment date. Compare projection error with prior years. Update reserve policy rather than asserting that the game uses a fixed formula. If a test conflicts with official notes, reproduce unmodded and submit F2 with a linked discussion. This method remains useful after a patch because the same protocol can identify what changed.

Year-end close, investment liquidation, and audit controls

A structured close converts the live projection into a funded payment and separates tax savings from wealth transfers.

Begin twenty game days before the boundary, or earlier when the configured year is short. Freeze a copy of the EconoView projection, current amount owed, displayed rate, cash, investment value, accepted orders, debt payments, and all planned capital purchases. Forecast each remaining day using conservative operating profit and cash timing. The close calendar should name the last safe date for an investment withdrawal, importer order, property offer, and optional expansion.

Reconcile profit to cash. Start with business operating profit, add back recognized COGS that was paid in earlier periods only for the cash bridge, subtract current inventory purchases, capital acquisitions, principal repayments, investment deposits, and tax payments, then add loans, asset sales, and investment withdrawals. This bridge does not change taxable profit; it explains why enough accounting profit can coexist with inadequate payment cash.

Prepare a deduction register. For every material purchase record category, item or address, amount, transaction day, projection immediately before, projection after the panel updates, displayed rate, control-save result, and confidence. Separate an official fact, such as the release adding more deductions, from an observed test, such as one property lowering one save's projection. Never merge several purchases and claim each caused the entire movement.

Prepare an investment liquidation ladder. Cash and near-term operating reserves are first. Funds intended for tax within the horizon are scheduled for partial withdrawal before the deadline. Long-term positions remain invested only when the remaining cash fully covers tax and operations. If two funds must be sold, compare current unrealized gain or loss, but do not delay a certain liability in pursuit of a recovery that the game does not guarantee.

Worked close: cash is three hundred thousand, current tax owed is one hundred thousand, next-year projection is two hundred twenty thousand, accepted orders are eighty thousand, and ten days of fixed obligations are seventy thousand. The minimum protected amount is four hundred seventy thousand before buffer, so the company has a one hundred seventy thousand shortfall. A fund worth five hundred thousand can supply that amount through partial withdrawal while leaving three hundred thirty thousand invested. A new two-hundred-thousand property purchase is not funded unless another source replaces its cash use.

Run sensitivity cases. If remaining profit is twenty percent above plan, recalculate tax at the displayed rate. If an expected deduction has only half the observed effect, increase the reserve. If an investment falls ten percent before withdrawal, test whether payment remains possible. If a rival attack lowers receipts, preserve tax and essential operations before marketing escalation. The close passes only when the combined downside avoids late fees without stopping profitable core stores.

After the payment, verify EconoView shows the correct remaining liability. Record partial payments separately and capture any fee. Do not assume the absence of an objective means a bill was paid when the panel says otherwise; Build 3672 corrected IRS timing, but a reproducible discrepancy still deserves an unmodded F2 report. Archive screenshots, save copy, and ledger totals so the next year starts from evidence.

Review performance after year end. Investment gain is ending value plus withdrawals minus deposits and opening value. Tax forecast error is actual bill minus the last pre-boundary projection, adjusted for transactions after that snapshot. Deduction test error compares the observed projected reduction with the actual bill difference when a clean comparison is possible. Use these errors to widen or narrow next year's reserve buffer rather than inventing a permanent rate table from one cycle.
