If X ~ B(n, p) and if n is large then x is approximately normally distributed with variance = np(1-p),Ī good rule of thumb is if np(1-p) > 5 you may want to use the normal distribution. In addition, you can use the normal distribution as an approximation to the binomial distribution and the poisson distribution. While there are exceptions and multiple factors are involved, generally speaking, married couples with a sole source of income benefit from filing jointly, while dual-income couples may suffer marriage penalties.The central limit theorem states that if you have a population with mean μ and standard deviation σ and take large random samples from a population, then the distribution of the sample will be approximately normally distributed. However, situations can and often do change, and while marriage may result in short-term tax penalties, it can potentially have long-term tax benefits. There are other conditions under which marriage results in a tax penalty. As a result of their combined incomes being subject to additional restrictions, it is possible for two married individuals with lower incomes to be disqualified from receiving tax credits they would otherwise receive.

Furthermore, having a lower joint income does not necessarily shield a couple from marriage penalties. This penalty can be significant if both individuals in the marriage have very high incomes since filing jointly can result in being subject to a higher tax bracket than the equivalent, combined income of two single people. This is referred to as the marriage penalty in the United States. In some situations, married couples end up paying more in taxes than single, otherwise equivalent, individuals. The calculator does not show results for this filing option. However, because this can be financially beneficial in only very rare cases, married couples usually opt to file jointly. Federal tax law allows assets to be transferred to a widow or widower without being subject to the federal estate tax.Īlthough married couples typically choose to file their tax returns jointly, some may choose to file them separately.

Marriage can help wealthy spouses protect their assets should they die.

Contributors must have earned income in order to contribute to IRAs, but filing jointly allows for a spousal IRA, which authorizes a non-working or stay-at-home spouse to contribute to retirement even though they didn't earn income during the year.

Filing jointly is usually better when the income disparity between spouses is high because this usually results in being placed into a lower tax bracket.

Those who fall under the married-filing-jointly category have access to these deductions, which can result in substantial tax savings.

Single filers miss out on certain tax benefits (earned income credit, education tax credits, student tax deduction for student loan interest, tuition and fees deduction, credit for the elderly and disabled, etc.).

The following are examples of some benefits that come with filing jointly: Step 2: Enter the mean, standard deviation, and data point in the input boxes. Step 1: Go to Cuemath's online normal distribution calculator. Spouses usually choose to file their taxes jointly once married. Please follow the steps below to find the probability of a value being higher or lower than a given data point using the normal distribution calculator. Benefits of Filing Jointly as Married Spouses Depending on the specific situation of the couple, dual-income married couples can experience the opposite effect, paying more in taxes than they would as single, otherwise equivalent, individuals, or as a couple with only a single income. Tax laws generally become more complicated after marriage, but marriage can present some opportunities to save additional money (compared to being single), particularly for those in single-income marriages or marriages in which there is a large difference between the income of the spouses. Normal distribution calculator (statistics) Normal distribution calculator Enter mean (average), standard deviation, cutoff points, and this normal distribution calculator will calculate the area (probability) under the normal distribution curve.
