## Mark to Market Taxation

Mark to Market Taxation is a regulatory accounting method used to value financial assets or liabilities at their current market price at the end of each reporting period. In the context of trading, this means that even if you have not sold an asset, you are taxed as if you had sold it at the current fair market value on the last day of the tax year.

This approach is common for active traders and certain financial instruments to ensure that taxable income reflects current market reality rather than just realized gains. By adjusting the book value of holdings to match market prices, tax authorities capture unrealized gains or losses.

This prevents investors from indefinitely deferring taxes by holding onto profitable assets. For cryptocurrency and derivatives, this can create liquidity challenges because a trader may owe taxes on gains that exist only on paper.

It essentially forces a periodic settlement of tax obligations based on fluctuating valuations.
