Regardless of the industry you're in, every business needs a way for customers to contact them. With an office of one, you may be able to get away with using just your local number, but as your business grows it's likely that your local number will no longer cut it and it will make sense to get an 800 number.
Yet there's a limit to how much you can put into an IRA every year. The limit on traditional IRA contributions for the 2018 tax year will be $5,500 for those younger than age 50, and $6,500 for those who are 50 or older. That's the same limit that's been in place for five years. If you make less than that amount from earned income from a job or self-employment, then your contribution is limited to your earned income.
There are no income limits for Traditional IRAs,2 however there are income limits for tax deductible contributions. There are income limits for Roth IRAs. As a single filer, you can make a full contribution to a Roth IRA if your modified adjusted gross income is less than $118,000 in 2017. If your modified adjusted gross income is more than $118,000 but less than $133,000, a partial contribution is allowed in 2017. If you are married and filing jointly, you can make a full contribution to a Roth IRA if your modified adjusted gross income is less than $186,000 in 2017.
