Understanding the 2018 Income Tax Brackets and Regulations
Following President Trump's signing of the Tax Cuts and Jobs Act of 2017 on December 22, 2017, notable changes impacted the tax landscape for 2018. The IRS released updated tax rate schedules reflecting these modifications. Taxpayers must familiarize themselves with the 2018 tax brackets and deduction adjustments when preparing their returns. It's important to differentiate between the tax year 2017–2018 and 2018–2019 filings, as each year’s rules differ. Taxable income excludes certain sources like inheritances and gifts, focusing primarily on earned income for taxation.
While the number of tax brackets remains at seven, the rates have shifted to 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Individuals and households need to reference the 2018 tax rate tables to determine their liability. For single filers, income brackets start at $0 and go up to over $500,000, with corresponding tax rates. Standard deduction amounts have also increased, with singles claiming $12,000 and married couples $24,000, reducing taxable income and potentially lowering tax burdens.
Married couples filing jointly and surviving spouses have brackets spanning from $0 to over $600,000, with rates following the same structure. Heads of households face similar brackets, with an $18,000 standard deduction. Filing separately retains similar tax structures, but with higher thresholds for the top rate and a $12,000 standard deduction. The removal of personal exemptions and the cap on state and local tax deductions at $10,000 are key changes. Mortgage interest deductions remain, but the loan limit has decreased from $1 million to $750,000.
The increase in standard deductions and your ability to maximize tax-advantaged accounts can lead to significant savings. Be aware of eligibility for additional deductions based on age or disability, and plan accordingly to optimize your tax benefits.
