Tax surprises compress runway.
A $74,000 advance tax payment due next quarter is not in your bank balance calculation. But it will reduce your available cash and shorten your runway. RunwayCal surfaces these obligations in your True Cash Position so you see the impact today, not the day it is due. Whether you operate in India, the US, Canada, the UK, the EU, or Australia, RunwayCal provides country-specific obligation types and filing calendars so you never miss a deadline. Every obligation feeds directly into your True Cash Position, reducing your available cash and adjusting your runway automatically.
What happens without tax obligation tracking
You miss a GST filing deadline and face penalties that compound on top of the original obligation. Late filing fees, interest charges, and potential audit triggers turn a manageable tax payment into a financial and administrative burden that drains founder time and cash simultaneously.
You report runway to your board without accounting for upcoming tax payments. A $74,000 advance tax obligation due in 60 days isn't reflected in your runway calculation, so your board makes strategic decisions based on numbers that will drop significantly when the payment comes due.
You discover a $50,000 advance tax obligation the week before it is due. Without a tax calendar connected to your financial model, obligations surface as emergencies instead of planned expenses. RunwayCal prefills obligation dates from country-specific calendars so you see them months in advance.
Country-specific calendars with smart estimation.
Track obligations across India, US, Canada, UK, EU, and Australia. RunwayCal estimates amounts from your existing revenue data and marks overdue items daily.
Tax tracking connected to your financial model
Country-specific tax calendars
Select your jurisdiction and RunwayCal prefills your tax calendar with the relevant obligation types and due dates. India: GST monthly and quarterly, TDS monthly, advance tax quarterly. US: estimated quarterly payments, state withholding. Canada, UK, EU, and Australia each have their own calendar templates. You don't need to research filing deadlines manually. The calendar shows every upcoming obligation with the amount, due date, and status.
Obligation types and smart estimation
RunwayCal supports GST, TDS, estimated quarterly payments, state withholding, advance tax, and custom obligation types. For standard obligations, the system estimates amounts from your existing revenue and payroll data. You review every estimate before it enters your financial model. Override the amount if your accountant provides a different figure. The estimation saves time on initial setup while keeping you in control of the final numbers.
Mark as paid, track what's outstanding
When you pay a tax obligation, mark it as paid in RunwayCal. The deduction is removed from your True Cash Position and the obligation moves to your paid history. Outstanding obligations remain as deductions, keeping your available cash number accurate. Daily monitoring checks due dates and automatically marks overdue obligations so nothing slips through. The paid versus outstanding distinction gives you a clear view of your tax liability at any point in time.
Connection to True Cash Position
Every unpaid tax obligation reduces your True Cash Position. This means your runway calculation already accounts for upcoming tax payments. When you tell your board you have 8 months of runway, that number reflects the $74,000 in tax obligations due over the next two quarters. No separate mental math, no forgotten liabilities. The connection is automatic: add a tax obligation and watch your True Cash Position and runway adjust in real time.
Multi-jurisdiction support
Operating across multiple countries? Each jurisdiction has its own obligation calendar with the correct filing dates and types. Track Indian GST alongside US estimated quarterly payments and UK VAT obligations. All obligations from all jurisdictions feed into one True Cash Position number. Multi-location businesses see entity-level tax tracking alongside their consolidated view. Your global tax exposure is visible in one place.
Tax deadlines should never be a surprise.
